Patent DE-2329562-A1 (DE)
Title: Selector for stepper switches - has spring loaded split contact block which allows two selectors to rotate
Inventor: HEINZ RUDOLF
IPC: H01H9/00

Title: Explosive compaction of metal and ceramic powders, fibres and foils - in which capsule contg. the mixt. drops into explosive
Inventor: PRUEMMER ROLF DR ING
IPC: C04B35/76
Filed: 1974-07-31
Abstract: Ceramic- or metallic- matls. and mixts. are explosively compacted by heating the matl. in a capsule and then subjecting to an explosion triggered by an impact igniter or an electrical contact, etc.; the speed at which the capsule is fed into the explosive device precluding any heat transfer to the explosive in the bried lapse of time occurring between insertion of the capsule and detonation. The heated powder may be in a vacuum or inert gas and the resulting compact may be sintered. Mixts. may be used which only react at high temp. and press. produced by the explosion. Fibres and metal foil may be included. Compacts are mfd. from soft metal powder, e.g. Al, or hard powders such as heat-resisting alloys. or mixts. which form cermets. Fibres can be embedded in powder or wrapped in metal foils; a bar of metal or ceramic may be used in place of powder.
Patent DE-2438195-A1 (DE)
Title: Reduced cost of liquid fuel-gas evaporation - by using evaporated cool as to a refrigerator and then fuel for a ship
Inventor: BRAEUTIGAM MAX
IPC: F17C13/00
Filed: 1974-08-08
Abstract: The system is especially for the transport of liquefied natural gas in ships. Containers for the gas are kept in an atmosphere of nitrogen inside a heat-insulated chamber. Before being burnt, as fuel, any escaping gas is passed through a heat exchanger in a refrigeration circuit contg. nitrogen that bathes the natural gas containers in their heat-insulated chamber. By cooling the nitrogen, the evaporation of the liquefied natural gas is reduced, or even controlled to match the ship's fuel requirement. Any leakage of nitrogen from the refrigeration circuit is made good from a reserve of liq. nitrogen, which in its turn is replenished by extracting nitrogen from the air.

Title: Current supply system for crane - has two multiple cable drums one rotating but with cable around both
Inventor: KROPIK ERNST
IPC: B66C13/14
Filed: 1974-09-26
Abstract: The current supply system, for a crane, has two vertical axis multiple drums above the crane's cog mechanism for the supply cable. One multiple drum is mounted unrotatably to the crane mechanism and the second multiple drum can rotate about its axis and is mounted on a crosspiece. The cable is placed under tension so that the length of cable unwound from the non-rotating drum is taken-up by the rotating drum. The advantage of this arrangement of cable drums lies in its simplicity, few components and compactness especially in respect of height e.g. by normal universal stripper about 600 mm can be saved. More revolutions of the tiny beam can also be attained.

Title: Ring valve for reciprocating compressor or pump - has sealing element of rounded or streamlined cross-section
Inventor: KRAMER CARL PROF DR ING
IPC: F04B39/10
Filed: 1974-10-02
Abstract: The valve seat (12) has inlet passages (5) formed from a series of concentric slots intersected by radial ribs. The outer edges (16) of the slots are bevelled and the neck (8) of the slot is rounded and there is a gradual increase in radial width across the thickness of the valve seat. The sealing elements are in the form of rings (16) with a circular cross-section. The absence of sharp edges and the provision of an airflow passage without 90 deg. turns reduces the pressure of the air when flowing through the valve. The rings (16) may also have elliptical cross-sections and be retained by coil springs or leaf springs.
