Abstract: The disclosed isostat for treating materials comprises a hermetic container connected to a gas supply means, an induction heater and an open-top working chamber that are arranged therein, the chamber being mounted above the heater and designed for placing the article to be treated and the working medium therein. The working chamber is made in the form of a vessel with double walls and a bottom therebetween, the inner wall of the vessel defines a reaction chamber, the bottom of which is located above the heater higher than the bottom between the walls of the vessel, the bottom between the walls is located lower than the exposure zone of the heater, and the isostat is provided with a heat-insulating chamber, the wall of which is located in the space between the walls of the vessel with a gap between the open lower butt of the heat-insulating chamber and the bottom between the walls of the vessel, and with a gap between the closed butt thereof and the upper open butt of the reaction chamber.

Abstract: The invention relates to the field of powder metallurgy, in particular to the design of autoclaves for manufacturing of composite materials by treatment of workpieces of discrete materials, mostly powders, at high pressures and temperatures.

Abstract: The invention relates to the equipment for high-pressure, high-temperature treatment of materials in liquid and enables to broaden the technological capabilities of an isostatic press. The isostatic press for treatment of materials in liquid comprises a multi-cylinder pressure vessel forming a hermetically sealed working chamber connected to a gas source. The open-top container for liquid is placed in the working chamber in such a way that a gap is created between the inner wall of the pressure vessel and the outer wall of the container. The container with the liquid and the treated material is placed on an electrically insulated heater which, in its turn, is mounted on a protective magnetic block.

Abstract: A system for controlling the temperature of the interior of a vehicle, e.g., a railway carriage, comprising a refrigerant circuit (18) having an evaporator (21) through which air is passed to outlets (24) to the interior of the vehicle. A condenser (25) of the refrigerant circuit (18) is cooled by liquid-containing pipes which extend over the entire height of the vehicle to a liquid/air heat exchanger (19). The refrigerant unit is arranged in or on the roof of the vehicle and heat exchanger (19) is arranged on or under the floor of the vehicle, or vice versa.
