Patent DE-2461266-A1 (DE)
Title: Wire coil winding machine - with toggle clamped pinch rolls
Inventor: SUTER ROLF
IPC: B21F3/00
Filed: 1974-12-23
Abstract: Wire coiling machine with pairs of pinch rolls arranged in front of the coiling head. Each pair consists of one roll assembly which is rigidly mounted in bearings in the machine frame and the other roll assembly is movably mounted and pressed against the fixed roll. The force clamping the two pinch rolls together is applied through a toggle. The movable roll is pendulum mounted in the machine frame and the toggle mechanism connects with this displaceable bearing assembly through an adjusting screw and disc spring arrangement.

Title: Injection moulding of hollow bodies - using three-part injection mould
Inventor: BOEHME KLAUS-DIETER DIPL ING
IPC: B29C45/00
Filed: 1975-01-15
Abstract: In the injection moulding of hollow bodies by producing two individual shells and subsequently joining these together (a) two separate shells are produced in a three-part injection mould, the central part forming with each outer part a cavity for producing one shell (b) the three parts of the injection moulding tool are subsequently separated from one another, the central part is removed and the two outer parts are brought together again (c) the two shells are combined to form a hollow body, an annular mould cavity being formed at the contact seam of the shells, (d) a thermoplastic moulding material is injected into the cavity to join the two shells together and (e) the mould is then opened and the finished hollow body removed. Eliminates the manual operations normally required for joining the individual shells together, so that a completely mechanised and programmed moulding process can be achieved.

Title: Variable geometry bent plate parabolic cylindrical mirror - has devices by means of which elastic line of mirrored plate may be continuously varied
Inventor: KLEINWAECHTER JUERGEN
IPC: F24S23/74
Filed: 1975-02-07
Abstract: A bent plate parabolic cylindrical mirror having variable geometry used e.g. in solar power generation plant, is constructed such that the elastic line of a mirrored flexible plate may be varied by a continuously adjustable pressure or tension devices in the form of pressure rods or tensioning wires having attachment points which may be moved around the mirror.

Title: Spike for snow tyre - with flanges about shaft to grip in tread and hard metal insert
Inventor: PULKKINEN JUKKA
IPC: B60C11/16
Filed: 1975-02-26

Title: Change-over valve for milk pasteurisation plant - can be thoroughly cleaned without dismantling or removing
Inventor: TUCHENHAGEN OTTO
IPC: F16K1/44
Filed: 1975-04-16
Abstract: Milk pasteurising equipment includes a changeover valve in which milk from the heater flows into the inlet (Z) and out through the port (U) to circulate back to the heater. When the required pastreurisation temperature is reached, compressed air admitted through the port (1) acts on the cylinder (2) to push the valve (4) off its seat (5) and press it onto the seat (7) to close the outlet (9). Further travel of the piston then pushes the valve (6) off its seat (8) and then pushes the seat (10) downwards to shut off the connection between inlet (Z) and outlet (U). The heated milk then flows out through the port (D). The construction of the valve facilitates cleasning without the need to remove the valve or dismantle it.
Patent DE-2520428-A1 (DE)
Title: Advance unit for packaged goods - uses engaging pressure rail to control advance speed through foil shrinking tunnel
Inventor: BECK HANS
IPC: B65B53/06
Filed: 1975-05-07
Abstract: The advance unit consists of a continuous rod chain conveyor and is for transportation of foil-wrapped goods through a shrinking tunnel. A pressure rail (21-23) is positioned alongside the feed path. The rail is fastened to the frame, so as to be displaceable normal to the surface of the advancE. The rail may be pressed against the rods (17) of the conveyor, so that during advance, the rods roll-off the rail. This automatically adjusts the effective advance speed of the transported goods (3) in the area determined by the length of the rail, relative to the advance speed of the rods. The rail is pressed onto the rods from above to reduce the speed and from below to increase the speed.

Inventor: JAECKLIN ANDRE DR
IPC: H01L21/261
Filed: 1976-02-02
Abstract: The production of a semiconductor device and an avalanche transition time diode consists of several zones with different concentrations of doped impurities.

Title: Hydraulic tractor brakes with single wheel control - has fail safe interlock for manual braking through balancing valve on servo loss
Inventor: REITZ WERNER
IPC: B60T13/16
Filed: 1976-07-07
Abstract: The hydraulic tractor brakes have separate master brake pistons and master control valve through which the rear wheels are separately braked, as well as any trailer brakes. Servo brake fluid is supplied by a pump to a distribution valve through which any hydraulically powered accessory can be supplied when the brakes are open. The master cylinders, when operated separately, operate on a balancing piston in the control valve to block the fluid flow to one of the rear wheels. In the event of servo failure a balancing control valve prevents the separate operation of the rear brakes and uses the full manual effort on the mater brake cylinders for manual braking of both rear wheels. The master brake cylinders and the master control valve can be mounted in separate locations for a compact layout.
