Title: Narrow width electric terminal - has control mechanism or dolly and spring clip in wiring plane to reduce dimensions
Inventor: MARQUARDT ERICH ING GRAD
IPC: H01R4/48
Filed: 1975-03-15
Abstract: The terminal is for use with electric sockets, switches and small electrical appliances and has a narrow shape to reduce space requirements that is sufficient to provide a secure fixture for the inserted holder and thus to ensure against inadvertent withdrawal of the holder.

Title: Acoustic vibration generator for liquid current - has cylindrical rotor with closed ends and inlet for liquid
Inventor: WARLAMOW WLADIMIR MATWEEWITSCH
IPC: B01F11/02
Filed: 1975-05-12
Abstract: A hollow cylindrical stator in the working chamber has a series of orifices in its side, and accommodates a coaxial rotor coupled to the drive and with orifices in its side one whole number more than those in the stator. Whenever the two sets of orifices coincide, liquid arriving in the rotor passes into the chamber. The rotor is a cylinder with closed ends, one having an opening for the passage of liquid to its interior. The size of the orifices in rotor and stator is determined by a formula taking account of rotor angular velocity and external radius, and the speed of propagation of sound into the liquid.

Title: Pipe fittings for channel sheets - made by roll bonding and expanding two sheets which are then cut to make the individual fittings
Inventor: STEINBERG FRIEDHELM
IPC: B21C37/14
Filed: 1976-04-14
Abstract: Connector and pipe fittings for channel sheets, where the fittings are made by cutting channel sheets contg. several interconnected fittings of the same or different pattern. The fittings are pref. made by selectively coating one metal sheet with a material which prevents welding in those zones which will form a cavity or pipe. This sheet is then covered by a second sheet and hot or cold working employed to join the two sheets, e.g. by roll bonding, in those areas which can weld together. The non-welded zones are expanded to form pipes, and the channel sheet is cut as required. In an example, two Al sheets are bonded together in some areas, and the unwelded zones are blown outwards to make channels used as heat exchangers in refrigerators. The invention is designed to make pipe elbows, T-junctions, Y-junctions, and similar pipe fittings employed to connect two channel sheets together, or to connect a pipe to a channel sheet.

Title: Ringless spinning equipment - has integrated air-tight assembly for air channel and spinning chamber with allowance for chamber movement
Inventor: RABINOWITSCH GEB EISENSTADT RO
IPC: D01H4/36
Filed: 1976-06-18
Abstract: The spinning equipment uses an eddying airstream to carry the fibres in a whirling and twisting path, to develop a yarn by ringless spinning. The spinning chamber, the air channel and the air collector form a complete hermetically sealed system. Part of the air channel is formed by a sleeve which is hermetically sealed to the spinning chamber and is airtight while sliding axially as the spinning chamber position is moved, the remainde r of the air channel being flexible to accommodate this movement. The design allows movement of the component parts without destroying the airtight seals, simplifying the service of the equipment.
