    Opis:
    An advanced, solvent-less resin based Combustible Cartridge Case (CCC), designed to resolve the inherent problems of shrinkage and limited mechanical strength associated with the gelatinisation of nitrocellulose, has already been developed. The felt-moulded components contain thermoplastic polyvinyl acetate (PVAc) resin as the binder and the enhanced mechanical strength is achieved by carrying out hot compaction of dry felts at an elevated temperature (105 ± 2 °C). Presently, resin based technology is adopted for tank gun ammunition and also for the developed modular CCCs, i.e. the Modular Combustible Case (MCC) for different types of artillery gun ammunition. However, during exhaustive trials conducted with the resin based CCCs in 120 mm tank gun ammunition at three temperatures, i.e. -10, 27 and 55 °C, severe geometrical deformation was noticed when the rounds were conditioned at 55 °C for 24 h., adversely affecting the loading of rounds into the gun chamber. This was attributed to the combined effects of softening of the resin at that temperature and the load of the projectile/ shell (14.4 kg) experienced by the CCC region during conditioning of the round in the horizontal mode. In order to resolve this problem of deformation, PVAc resin was required to be modified. The PVAc resin was modified to the form of a nanocomposite. PVAc nano composite was prepared by dispersing organically modified nano clay, i.e. Cloisite 30B, into the resin before making the CCCs. The nanocomposite of PVAc resin was characterized by FTIR, DMA, softening point measurement etc. The results showed a remarkable improvement in the glass transition temperature (Tg) and in the softening temperature of the modified PVAc resin. This modified PVAc resin was used to prepare CCCs. Furthermore, these CCCs were coated with hexamethylene diisocyanate (HMDI) on the inner and the outer surfaces. The isocyanate coating becomes crosslinked in the matrix, thereby improving the softening point as well as the mechanical properties of the CCCs. These modified CCCs were repeatedly tested at 55 and 60 °C for 24 h. After testing, it was found that no deformation had taken place and the assembled rounds were easily loaded into the gun chamber. The use of the PVAc nanocomposite in the preparation of resin based CCCs, followed by isocyanate coating, is an effective means of achieving the required improvement in structural integrity of the resin CCCs at elevated temperatures.

    Opis:
    Tens of millions of printers are sold each year, including copiers and multifunction devices. Each printer needs an ink or toner cartridge, depending on the type of printer. This is where the problems arise that anyone who owns such a device has encountered – the price and availability of cartridges. A set of original cartridges for the printer we bought can sometimes cost more than the printer itself. On the other hand, it is not always possible to buy cheaper replacement consumables. This is often due to the fact that the manufacturer of the printer has implemented a Digital Rights Management (DRM) protection in the chip connected to the cartridge. Bypassing such protection is not trivial, and when a way to do so is learned, it is not disclosed because of the commercial value of such knowledge. The goal of this paper is to determine if it is possible to find out for ourselves how selected DRM protections work by using reverse engineering, and to develop a way to reset these protections so that we are not tied to the price and availability of consumables on the market, as we can remanufacture our cartridges ourselves, which is especially important in the context of the Right to Repair.

    Opis:
    Bath gray water organoleptically did not appear to be significantly contaminated liquid. However, in order to re-use them, they need proper treatment. When recirculated in a household, they cannot pose a threat to human life. Based on their appearance, it seems that the solution to the problem is the use of cartridges filter. The article presents the results of the filtration of gray water from the bath through the filtration system with a housing double stage polypropylene-carbon filter FCCA-STO and to determine the impact of individual filter layers on wastewater treatment, tests were carried out on a single polypropylene FCPS10 and carbon FCCA filtration cartridge. The aim of the study was to determine the suitability of the selected housing filter cartridges for the treatment of bathing gray water for their reuse. For the tests were used natural bathing gray water from a two-family building inhabited by seven people. Wastewater were fed to the filter with a constant flow rate of 0.1 dm3·s–1. The assessment of the work of the filters based on parameters such as: COD, BOD5, suspension, dry residue, decay and turbidity. The conducted tests have shown a slight improvement in most of the quality parameters of gray water after filtration through selected housing cartridge filters. Only for turbidity, the reduction in the value of the pollution indicator was noticeable. The cartridge filters used in tests, acted like ordinary mechanical filtration cartridges. For the considered gray water, the use of analyzed cartridge filters can only be used for their initial purification.

    Opis:
    Water is one of the humans’ basic needs that are essential in daily lives. The water use related to the production of the food processing industry must at least meet the quality standards required for drinking water. The Production process water is obtained from the artesian well that has been treated with a physical treatment process. The microbiological examination result of total Coliform is 8.6 MPN/100 ml meaning that it does not meet the quality standard requirements, which is 0 MPN/100 ml (The Minister of Health Regulation Number 492 of 2010, concerning Drinking Water Quality Requirements), it is necessary to treat the production process water using a Melt Blown Filter (MBF) and UV-C rays. The purpose of this study was to determine the differences in the variation of the 1, 3, and 5-micron of Melt Blown Filter cartridge 10” in reducing the amount of total Coliform, as well as the water hardness and their effect on disinfection using UV-C rays. The type of research used is experimental research with a pretest-posttest without control research design. There is a reduction in the average total Coliform after the treatment using a Melt Blown Filter, with a result of 1, 3, and 5-micron as 2.95 MPN /100ml, 3.61 MPB/100 ml, and 7.31 MPN/100 ml with a percentage reduction of 100%, 94.5%, and 82.4%, respectively. The average total Coliform using the Melt Blown Filter equipped with the UV-C rays treatment resulted in a reduction of 1, 3, and 5-micron as 2.95 MPN/100 ml, 3.95 MPN/100 ml, 8.88 MPN/100 ml respectively, with a reduction percentage of 100%, for each treatment. The data analysis for total coliform using the One-Way ANOVA test resulted in a pvalue of 0.001, the effective variation obtained is 1-micron MBF equipped with UV-C rays. The analysis of results pertaining to the water hardness data showed that the use of Melt Blown Filter could not reduce water hardness, but the UV-C rays could still be used accordingly. The data analysis for water hardness was performed using KruskalWallis with a p-value of 0.820, meaning that there are no differences in Melt Blown Filter variation on the results of total water hardness value.

    Opis:
    Thermal and economic conditions that have to be satisfied by heat exchangers in heat and power generation cause that analysis of the influence of the working medium flowing in heating cartridge pipes is essential for designers. It follows from the state of the heating cartridge after its many-year operation. Because of strength issues that affect design and thermal solutions, it is important to evaluate the influence of heat exchanger working conditions on the possibility of its stability loss. One of the most important elements of heat exchangers are perforated bottoms – perforated plates of significant thickness in which heating cartridge pipes are mounted. For designers of heat exchangers, the definition of loading and analysis of all possible types of failure is of special importance. The paper is a continuation of the conducted investigations on heat exchangers where the calculations of elastic stability of perforated bottoms with pipes inside were developed for inelastic regions.

    Opis:
    In an armament system an electro-explosive device (EED) essentially converts electrical energy into heat which further initiates the explosive train with its accompanying temperature rise. The first function of an EED in a power cartridge is to provide adequate electrical current to cause ignition of the highly sensitive explosive i.e. lead styphnate. The electrical current accomplishes ignition by heating the bulb of lead styphnate which produces enough heat to cause the booster to ignite. The booster which is in the immediate vicinity augments the ignition of the propellant further. The igniter must be held firmly in place with the booster in the tube. Understanding of the initiation of explosives using a bridge wire in EEDs is important for engineers, designers and scientists to develop new theories. In this research article, theoretical and experimental work has been reported pertaining to bridge wire devices in power cartridges for water-jet applications. The objective of the present research work is to use lumped parameter analysis of a bridge wire in an electro explosive device of a power cartridge for water-jet application. A lumped parameter theory is proposed for the analysis of EEDs. A time constant of 3.35 s has been determined using the lumped parameters. The Biot number is less than 0.1 indicating that transient phenomenon is applied.

    Breakdown of rolling stock axle-boxes if not detected in due time may cause a rail accident or disaster. At present, a lot of advanced technologies, modern equipment and devices, which “recognizes” faulty axle-boxes when the train is in motion, have been implemented. However, the timely identification of breakdown of rolling stock axle-boxes still is an acute problem, the initial stage of damage emergence being especially problematic. Presently, rolling stock axle-box breakdown is determined according to the higher than permissible temperature of the axle-box body. The article provides statistical data of dangerously heated axle-boxes, determined train delay durations, the number of delayed trains by danger level, and dependence of damage on the season. After systematization of data on axle-box damage and heating temperatures of broken axle-boxes, heating tendencies of axle-boxes of freight wagons are described. Finally, basic conclusions are given.

В настоящее время внедрено много передовых (прогрессивных) технологий, современного оборудования и приспособлений, которые «распознают» неисправную буксу во время движения поезда. Но, несмотря на это своевременное, обнаружение неисправности буксы остается острой проблемой, особенно в начальной стадии повреждения. В настоящее время повреждения букс подвижного состава определяются по температуре нагревания корпуса буксы. В статье предоставлены статистические данные о буксах, нагревающихся до опасного предела, установлена продолжительность задержек поездов, количество задержанных поездов по уровням (категориям) опасности и зависимость нагрева букс от времени года. Тенденции нагрева букс грузовых вагонов описаны на основе систематизации данных о неисправностях букс и температуры их нагрева. В конце предоставлены выводы.

    Opis:
    This paper discusses the design analysis of closed vessel (CV) for power cartridge application in water-jet disruptor. In this article, various design theories are presented in which the vessel is subjected to internal pressure. CV is a kind of pressure vessel utilized to evaluate the performance of power cartridge used for water-jet application. It is a test vessel which generates pressure - time profile by burning the propellant. Energy derived from burning of the propellant of power cartridge aids in neutralizing Improvised Devices (IED's). This energy creates high water-jet plume in the disruptor. In order to evaluate various performance parameters of the cartridge, CV design plays a vital role in the research and development activities, including, development, life trials, production, lot proof trials and life extension / life revision trials. CV is one of the methodologies / techniques from which energy generated is measured in terms of the maximum pressure (Pmax) and the time to maximum pressure (TPmax). This paper also discusses about various design aspects using the finite element method (FEM) and their comparative results with different design theories. In the light of these theoretical, numerical, and experimental works, it was recommended that octahedral stress theory or van Mises theory should be used for vessel design. This satisfies the designer requirements. FEM analysis tool helps in reducing time & development cost.

    Opis:
    Power cartridges are gas generators utilised to drive a liquid projectile for disruption of suspect improvised explosive devices (IED’s). The purpose of a water-jet disruptor is to destroy the suspected IED. A novel method was devised for pressure measurement at the exit of the cartridge for launching liquid projectile. An experimental test set-up was designed and fabricated for measurement of projectile velocity and the propellant gas pressure in a velocity test rig (VTR). In these experiments, double base propellants having different physical and chemical properties were utilised to drive the solid projectile. This projectile was made of nylon material. This projectile velocity measurement is an important parameter in the armament field. An experimental study is the unique design feature. It is responsible for the measurement of pressure at the exit of the cartridge and the projectile velocity at the muzzle end of the barrel. The projectile velocity was measured using high speed photography. The pressure was measured using a pressure sensor. The maximum projectile velocities for spherical ball powder and NGB 051 propellants have been experimentally measured as 384.23 m/s and 418.32 m/s, respectively. Experimentally the maximum pressures for spherical ball powder and NGB 051 propellants have been evaluated as 50.12 MPa and 63 MPa respectively from data gathered by the acquisition system. The standard deviation between the experimental and theoretical values for the projectile velocity varied from 12.57 to 13.88 for spherical ball powder whereas it was 5.33 to 7.09 for NGB 051 propellant. The percentage error between the experimental and the theoretical values of the projectile velocity was less than 10 for both propellants.

    Opis:
    The aim of this study was to verify the criteria for selecting pleated filter partitions used in passenger car engine filters. The paper presents the problem of optimizing pleated air filters in the direction of minimizing pressure drop, which is the source of engine energy losses. Two criteria for selection of a paper filter partition for specific operating conditions of the filter and the engine are presented: criterion of permissible separation speed and criterion of permissible pressure drop. The actual filtration area of 44 paper pleated filter elements used in passenger cars and the air stream flowing through the filter were determined, which made it possible to calculate separation speed. In 62% of the analyzed filter inserts, the calculated separation speeds are within the speed range recommended by the constructors, ʋFmax = 0.06-0.12 m/s. Exceeding permissible separation speed ʋFmax = 0.12 m/s was found mainly in supercharged engines. Negative effects of engine operation with an air filter with too small separation area are presented, in the form of increased pressure drop and energy loss of the engine as well as shorter car mileage to reach permissible pressure drop.
