Title: Spring loaded radial piston pump - has piston cross bore to outlet port, and piston rotation prevented by ring on eccentric in piston slot
Inventor: GLOCK WILFRIED DIPL ING
IPC: F04B7/04
Filed: 1975-12-19
Abstract: Radial piston pump has a number of cylinders (10) with pistons (3) arranged in a common plane, the pistons being driven by an eccentric (2) against a spring (8) whereby the medium is drawn in through cross bores (7) in the pistons during the suction stroke and moved into a common pressure line (12) via valves (11) during the delivery stroke. Each piston is connected with the valve via a direct duct (6) to the cylinder which duct lines up with the cross bore(s) (7) when the piston is in its TDC region.

Title: Hydraulic pipe coupling connected under pressure - has load and supply end valves held together by hydraulic force
Inventor: FISCHER WALTER DIPL ING
IPC: F16L29/04
Filed: 1976-09-23
Abstract: The coupling for hydraulic pipes is connected in pressurised state. Each coupling half has a spring loaded hydraulically loaded valve. The valve heads are contacted on coupling and the load end valve is pushed around the pressurised valve on the load side pipe end. The connection prevents pressure surges and fluctuations, without need for additional operation after the coupling halves had been connected. The hydraulic pressure loaded surfaces exert force in the closing direction of the pressurised fluid supply end valve which is greater than those for exerting force in opposite direction. The cross section of the pressurised fluid supply end valve is greater than that of the load side valve (4).

Title: Heating wire applicator for glass panes - with wire coating jar and sticky tape fixing
Inventor: FRANK DIETER
IPC: H05B3/84
Filed: 1976-11-17
Abstract: Panes with an embedded aerial wire or heating element wire, e.g. for the rear window of a motor car, are produced by applying to the pane parallel wires, coated with a binder. Immediately following the application, the wire is held by a self-adhesive strip which is removed again when the binder has become hard. Plain panes can thus be converted to heated panes without requiring expensive machinery. The original unheated pane need not be discarded.

Title: Automatic tube assembly line - uses model built up from random lengths positioned so that joints to be welded lie in desired areas
Inventor: GUREVITSCH VLADIMIR ZACHAROVIT
IPC: G01B7/04
Filed: 1976-11-23
Abstract: A tube assembly model (I) is first manufactured which has exactly the same length as the tube lengths which are to be manufactured. On the model, those regions over which no joints are allowed are marked. A second model (II) is then built up from random lengths of tubes in random sequence.

Title: Frozen meat cube cutting machine - with cutter discs on drum having alternate protruding and re=entrant teeth
Inventor: HAGER JUERGEN DIPL KFM DR
IPC: B26D3/22
Filed: 1977-05-04
Abstract: The cutter drum is equipped with different types of cutters which alternate in the axial direction.

An ultrasonic device (3) is located on the end of the air jet tube (1) near the air jet (C) and almost parallel to it. This device emits a pulse which is received and reflected at the point of use (B). A receiver installation (10, 11) emits a signal proportional to the pulse to the timing device (4, 5). In this way, the position of the hands which forms the point (B), determines the temperature of the air jet.
Patent DE-2730603-A1 (DE)
Title: Paste filling and closing system - saves time by not braking closing mechanism to complete stand still in filling period
Inventor: NIEDECKER HERBERT DIPL ING
IPC: A22C11/00
Filed: 1977-07-07
Abstract: A continuous filling and closing system for pastes, such as sausage meat, in tubular packages applies a brake to the closing mechanism drive after a sheath has been released for the filling of the next sausage. During a filling operation, the drive of the closing mechanism at the given size of the portion is braked only to a level where it does not come to a complete standstill. This saves the time required to accelerate the closing mechanism drive to its full working speed. More time is available for filling operations so that the machine has a higher productivity.

Title: Document shredding machine - has driving assembly with elastic element to protect motor against overload
Inventor: GOLDHAMMER ALBERT DIPL ING
IPC: B02C18/24
Filed: 1977-10-29
Abstract: The shredding machine is fitted with a device which ensures a controlled reversing rotation of the counter rotating cutters when excessive bulk reaches the cutting gap. The counter rotating cutters are driven from an electric motor by a chain drive. The sprocket (4) is keyed on the shaft (9) working together with pin (10) and inserted elastic element (11). During the normal operation the elastic element is in a compressed state. When the electric motor becomes overloaded due to excessive paper bulk, the compression of the elastic element increases and it exerts pressure in direction contrary to the normal rotation and the electric motor starts rotating in opposite direction.
