Title: Peel-off self-adhesive workpiece-protective film made of plastic
Inventor: DOERING ERICH
IPC: C09J7/22
Filed: 1981-08-18
Abstract: A peel-off self-adhesive workpiece-protective film made of plastic will normally have on its bottom surface a uniform coat of a pressure-sensitive adhesive. To facilitate peeling off, it is proposed to allow the coat of adhesive to become effective only in selected regions. This can be done by applying the adhesive merely in the form of longitudinal or transverse stripes or in spots. It can also be applied uniformly and covered up (masked) in such a way as to leave stripes or spots uncovered. It is finally possible to use an uncoated protective film which has either been provided in the envisaged adhesive areas with perforations and on top of these with self-adhesive tapes, so that their uniform adhesive coating becomes effective on a workpiece to be protected only through the perforations, or has had adhered, to its bottom surface, self-adhesive tapes which each have on their top surface a coat of self-adhesive in the form of spots or the like.

Patent DE-3143473-A1 (DE)
Title: Single-tube shock absorber exercising self-regulation on both sides
Inventor: FAEHRMANN KURT
IPC: F16F9/512
Filed: 1981-11-03
Abstract: The invention relates to a single-tube shock absorber which can be used for liquid or gas for damping, having the following components in the piston (3): a piston valve plate (3b) and a restriction plate with a reducing cone (8), which control the pressure and suction flow via the valve limiting insert (6a), and a compensating piston (7a) installed in the bottom part. The object on which the invention is based is to amplify the damping (drawing C) and is achieved by virtue of the fact that when the piston (3) moves - either upwards or downwards - a pulse is initiated in the components situated in the interior: the piston valve plate (3b) controls the volume of the piston rod (6) synchronously with its surface volume and the valve limiting insert (6a) regulates the flow during the high-pressure process with its restriction openings (4), the restriction plate with the reducing cone (8) and its helical spring. The reducing cones (8) are seated on a restriction plate and are pressed firmly into the restriction opening (4) by a helical spring under the restriction plate (8). After overcoming the resistance of this helical spring, the gas or liquid can push the reducing cones (8) out of their seat in the restriction openings (4) and flow from working space A to working space B is possible. During low pressure, the piston valve plate (3b) is pressed out of its seat by the valve limiting insert (6a) and, as a result, flow from working space B to working space A is possible. During this procedure too, there is slight damping.

Title: Spiral motor
Inventor: SPEER ANTON DIPL ING
IPC: F03G1/00
Filed: 1982-05-10
Abstract: A spiral motor is a device with steel bending sheet or steel bending strip specially formed for the purpose, which is bent and tensioned according to a corresponding spiral function r = f( phi ) and in which energy thereby produced is converted into an open system of forces and, acting with constantly resulting torque, causes a persistent rotation about the centre of rotation of the rotary disc of the spiral motor. A spiral motor has a long life, does not need any explosive and combustible fuels, as a result of which no environmental pollution is produced, either, and whilst operating it is quieter than electric motors. Its overall volume is approximately equal to that of a conventional motor of the same kilowatt power. It is suitable for motor vehicles of all types and in industry, the aviation industry for aircraft and in electricity generating stations for driving electric generators for generating current. There is therefore no need of this ballast with explosive and combustible fuels in the tanks, which conventional motors require. Such spiral motors are independent of any fuel consumption and afford a very long operating life. <IMAGE>

Title: Cutting device for safety belts
Inventor: NETTO ROLF
IPC: B60R22/32
Filed: 1982-06-16
Abstract: In a cutting device for safety belts in vehicles, a severing handle with a blade for severing the belt is arranged in the region of the belt deflection clip arranged at the side of the shoulder. The blade support is provided on the sleeve-like web of this deflection clip, an essentially pocket-like reception device for the at least partial enclosure and displaceable guidance of the severing handle being arranged on the said web. The broad side surface of the severing handle, which predominantly takes the form of a flat flap, is parallel to the broad walls of the sleeve-like deflection clip section, and the blade is released from the blank of the flap and bent out of its plane. As a result of this, injuries inflicted by the cutting device itself are avoided, as the latter has virtually no projecting parts and is integrated into the deflection clip in an optimum fashion.
