Patent DE-2344269-A1 (DE)
Title: Combined heat pump and refrigerator - has gas circuit with isothermal expansion and compressor for preheating
Inventor: EIGNER OTTO
IPC: F25B29/00
Filed: 1973-09-01
Abstract: The gas heat pump can be used also as a refrigerator and a heating system. The system has a compressor for adiabatic compression of air in which the air is heated. This hot air can be used directly for heating of rooms. The air can also be used for producing hot water and it flows into the heating system which contains an insulated water tank. The air is then passed into the heating system in the container whose water is also heated. Subsequently the air which is at high pressure is passed through a heat exchanger for preheating the counterflowing cold air which arrives from the expansion engine. The condensation heat of the refrigerant vapour is transmitted through the walls of a precooled pipe to the expanding air. This air is passed into a receiver tank and from there to the compressor.

Title: Large pressings removed from press after ejection - using conveyor made of magnetised rods carried by two chains
Inventor: JUNGINGER GEORG
IPC: B21D43/12
Filed: 1973-12-07
Abstract: The rapid removal of a pressing out of the line of sheet travel during the continuous mfr. of large components is achieved by arranging that when the upper ram travels upwards, ejectors push the pressing downwards onto a conveyor belt moving at 90 degrees to the direction of the sheet, the belt being provided with cavities through which the dies can operate. The novelty is that the conveyor belt consists of two endless chains in which the links are joined by rods to form a transport surface. The rods are pref. made of a permanent magnet material or from a material which can be magnetised in the usual way. The method prevents a cushion of air forming between the large pressing and the conveyor belt; this cushion is most undesirable because it precludes rapid removal of the pressing and thus reduces the number of press strokes possible in a given time.

Title: Hollow charge protection for armoured vehicles - uses steel plates with integral layers of high melting temp. material
IPC: F41H5/007
Filed: 1974-03-12
Abstract: The protective arrangement against hollow charges for armoured fighting vehicles makes use of high melting temperature, low density materials. Alternatively the material can have a high evaporation temperature. This material neutralises the high temperature penetrating the metal core of the hollow charge by absorbing its energy. The steel armour plates have hollow recesses which accommodate, for example, pressed graphite. This material is of low weight and absorbs large quantities of thermal energy and hence greatly reduces the penetrating power of the hollow charge core. The use of lightweight material reduces the need for additional steel plate thickness which may have an adverse effect on the armoured vehicle design.
