Title: Conductive metal strip forming machine - has wire formed between saddle and anvil which are ultrasonically vibrated at different frequencies in inert atmos.
Inventor: TYAVLOVSKY MICHAIL DOMINIKOVIT
IPC: B21C37/02
Filed: 1977-04-15
Abstract: The metal strip is made from a metal wire, ultrasonic vibrations being imposed on the system and propagated at an angle to the longitudinal axis of the wire. The ultrasonic energy is used to prevent the welding of the metal to the tool under vacuum conditions or in inert medium and of high temperatures. The metal wire (3), the saddle (1) and the anvil (2) are placed in an inert medium relative to the metal of the wire, saddle and the anvil material. Subsequently wire is heated to the temperature of plastic deformation of the wire metal. Additionally the ultrasonic vibrations are imposed simultaneously to the saddle and the anvil. The frequencies of the vibrations imparted to the anvil are higher than those imparted to the saddle.

Title: Flexible fast xerographic photoreceptor - having aluminium-aluminium selenide and photoconductive layers on nickel or copper substrate
Inventor: LING CHESTER H K
IPC: G03G5/08

In an example, the photoreceptor was produced by depositing Al on a Ni (plated) strip, mesh or matrix in vacuo in an oxygen-free atmos., pref. in an inert gas, followed by a Se (alloy) layer from a Se vapour cloud contg. high energy (inert gas) ions.
Patent DE-2740821-A1 (DE)
Title: Swashplate type hydraulic pump or motor - has pressure cylinders and sleeve on shaft to equalise axial forces on bearings
Inventor: STUMPMEIER FRITZ ING GRAD
IPC: F04B1/20
Filed: 1977-09-10
Abstract: The machine has a shaft with an endplate which carries the ends of pistons. The pistons reciprocate in cylinders in a drum which is inclined at an angle to the shaft. The shaft is carried in two roller bearings which take both radial and axial thrust. The angle at which the rollers are inclined is the same for both bearings. Cylinders which receive fluid pressure exert an axial force on the housing ring of the drive side bearing. This is transmitted by a sleeve on the shaft to the piston end bearing and equalises the axial forces on the two bearings.
Patent DE-2746719-A1 (DE)
Title: Power generator extracting energy from flowing water - has spring-mounted frame with ratchet arms at rear to turn pinion
Inventor: DOGAN ALI
IPC: F03B17/06
Filed: 1977-10-18
Abstract: The upper and lower sides (16) of a frame are held to a fixed base (10) by springs (12). The front of the frame is formed by pivotted flaps (18, 20) which are held closed by springs (26, 28) from the base. Water impinging on the flaps moves the whole frame back. After a sufficient movement the springs (26, 28) holding the flaps closed are relaxed so that the pressure of water opens the flaps. This allows the main springs (12) to pull the frame forward again. The back (34) of the frame carries two rods (36, 38) which have ratchet teeth (64, 70). These turn a ratchet pinion (46) on the output shaft (44).

Filed: 1977-11-14
Abstract: The system produces and fits a cover of thin metal foil onto e.g. a can, by stamping a disc out of a plate and then shaping it by a drawing punch. The shape cover (6a) is inserted by the punch (10) in the can (1) to a depth corresponding to the final position in the latter, after which the punch exerts a pressure in the outwards direction on the portion of the cover protruding above the edge of the can. Finally a pressure can be exerted on the outwards-bent edge of the cover in the axial direction of the can.

Title: Safety system for fluid pipe - has solenoid valve closed by signal from sensor detecting uncontrolled fluid leakage
Inventor: PREISER FRIEDRICH DIPL ING
IPC: F16K21/16
Filed: 1978-02-17
Abstract: The electrically-controlled protection equipment is for pipes, hoses etc. delivering electrically-conductive liq. media to user units. If liquid discharge becomes uncontrolled, this is detected and the flow shut off. A solenoid valve is mounted in the fixed part of the pipe upstream of the hose leading to the consumer unit. Leaking fluid strikes a detector under the latter, and which deenergises the solenoid valve via an amplifier, shutting off the flow.

Title: Transversal filter for echo compensator - has delay register and coefficient register for telephone subscriber's circuit in digital TDM system
Inventor: LECHNER ROBERT DIPL ING
IPC: H03H17/02
Filed: 1978-12-08
Abstract: The transversal filter has a shift register delay chain and a coefficient shift register determining the filter's weighting coefficients. The register stage contents are averaged with the echo of a test pulse and then written back into the register in the adjustment mode of the filter. In the compensation operating mode of the filter the contents of the coefficient register are moved out in the opposite direction and multiplied step by step with the contents of the data shift register. The resulting products are passed to an adder that produces the filter's output. The coefficients are not continuously adapted but only adapted during the adjustment mode, which alternates with the operation mode.
