Opis:
The results of the research on the development dynamics of passenger car fires as presented in this study resemble those given in articles [3] and [4]. The following conclusions can be drawn from the analysis of its results: 1. The dynamics of a car fire development mainly depends on ventilation. 2. It is difficult to start a fire in a tightly closed car. 3. The maximum temperature of a car fire in each experiment exceeded 1,000°C (by not more than several dozen °C). 4. Under the engine cover, plastic elements are damaged, while parts from an aluminium alloy partly melt. 5. After the fire damages window panes or the car is opened the temperature inside the vehicle grows very fast to more than 1000°C. This takes 2 to 5 minutes. 6. In the course of the fire, dangerous phenomena take place, posing risks for persons near the car, such as e.g. the breakup of servos. 7. A passenger car fire can last for more than an hour.

Opis:
The paper presents the most important events in the history of the development of the thermovision usage in Fire Services in Poland. The first attempts to use the thermal imaging cameras in fire protection in Poland and in the world have been described. Firefighting and Rescue Units were first equipped with thermal cameras for tactical operations in 1997. In the following years the Fire Service Units were continuously provided with more thermal equipment. Attempts have been made to use infrared pyrometers to detect fires. The paper also presents the current state of thermal imaging cameras equipment in Fire Services and information how the cameras are used. In order to present the usage of cameras in the actions of Fire Services, the statistics on thermal devices contribution in actions in the selected poviat has been drawn up. The data are presented in Table 1 and Table 2. The final conclusions show the directions for development of the thermovision usage in fire protection and rescue actions.

Opis:
The paper refers to earlier publications of the author, on identification of properties of thermomechanical, chemically hardened core/mold sands. In that earlier period, first version of the original DMA apparatus, produced by a Polish company Multiserw-Morek, was used. The Hot Distortion (HD) study results, published by the author in 2008, referred to phenomena accompanying a thermal shock in real conditions of thermal interaction of a liquid alloy on a mold, in reference to a shock possible to obtain in laboratory conditions, without use of liquid alloy as a heat source, with analysis of solutions applied in the DMA apparatus. This paper presents author’s observations on testing a new, innovative version of the LRu-DMA apparatus, containing a module allowing the Hot Distortion (HD) study. Temperature of specimens achieved in the case of the gas burner heating reaches values definitely above 800°C on the heated side and 610°C on the other side. Using an electric radiator, with maximal temperature of 900°C allows obtaining temperatures in between 225-300°C.
