Abstract: FIELD: storage of foodstuff. SUBSTANCE: refrigerator has condenser communicating through one liquid piping and throttling valve with evaporator connected to inlet chamber of steam jet and through other liquid piping and intermediate vessel, with steam generator connected to steam-jet operating nozzle. Condenser communicates with steam-jet diffuser through steam piping. Volume of intermediate vessel corresponds to that of steam generator; the former is at their elevation than the latter. Their spaces communicate through piping in upper and lower zones. Cold generation method of steam-jet refrigerator involves liquefaction of refrigerant vapors in condenser, throttling of one flow, liquid supply to evaporator, its boiling with heat transfer from cooled volume. Other flow of liquid is passed from condenser through intermediate vessel to steam generator wherein liquid is brought to boiling temperature to generate high-temperature energy carrier (steam) that goes to steam-jet operating nozzle and provides for inflow of low-temperature refrigerant vapor from evaporator. Refrigerant vapor goes to condenser. Liquid is fed to steam generator, energy-carrying steam is produced and fed to steam jet in three stages. EFFECT: enlarged functional capabilities. 3 cl, 1 dwg

Truncated surfaces of pyramids form a space where inner punches are installed in contact with inner surfaces of outer punches through insulating spacers. Side surfaces of inner punches form gaps where deformable inserts are disposed, whereas inner surfaces of inner punches form compression chamber with disposed therein deformable container made of heat and electric insulating material with inner cavity for receiving material to be processed, height to width ratio of the compression chamber lying in the range 1.03 to 1.4. Inside the shell, there are means to overlap gaps between side surfaces of outer punches, which are electrically insulated from the latter. Arrangements are also available providing heating and measuring circuits and therefore automation of the overall process, arrangements for cooling outer and inner punches, and means for convenient removal and installation of deformable container with material.

Abstract: Изобретение относится к использованию в производстве фасонных профилей высокой точности малой площади поперечного сечения (до 100 мм 2 ). Фасонные профили высокой точности (ФПВТ) относятся к новым видам эффективного металлопроката, применение которых в приборостроении и точном машиностроении обеспечивает повышение коэффициента использования металла до 0,90-0,95. Существующие технологии производства ФПВТ с малой площадью поперечного сечения (до 100 мм 2 ) включают в себя большое число чередующихся операций холодной пластической деформации, термической обработки (рекристаллизационного отжига) и подготовительных к деформации операций. Многоцикличность технологии повышает себестоимость профилей, в ряде случаев ухудшает качество продукции, возрастает глубина обезуглероженного слоя, снижается уровень механических свойств. Совместное использование скоростных способов нагрева, горячей пластической деформации и регламентированного охлаждения во многом позволяют устранить эти недостатки и расширить возможности производства указанных профилей.
