Patent DE-3314062-A1 (DE)
Title: Lock angle plate with stabilising plate
IPC: E05B15/02
Filed: 1983-04-19
Abstract: The lock angle plate with stabilising plate for wooden frames is provided especially for burglar-proof doors, in which high compressive stresses acting on the lock angle plate (2) by way of the door leaf (24) are presupposed. A high load-bearing capacity of the lock angle plate (2) is achieved in that the leg has passing through it fastening elements in the form of screws (14), (14') which penetrate into threaded bores (4), (4') in the stabilising plate (1), anchoring themselves there, after the stabilising plate (1) is fastened to the surface (16') of the wooden frame (16) by means of wood screws (13). The high load-bearing capacity of the lock angle plate (2) is achieved in that the axis of the passage bore is as near as possible to the leg surface (7'). This prevents the leg (5) of the lock angle plate (2) from bending when the lock plate is subjected to a load. All the bores and recesses both in the stabilising plate and in the lock angle plate are so designed that left-handed and right-handed doors can be equally equipped. <IMAGE>

Patent DE-3400951-A1 (DE)
Inventor: KRATT ALFRED DIPL ING
IPC: F02D31/00
Filed: 1984-01-13
Abstract: Method and device for regulating the rotation speed of an internal combustion engine of which the idle filling regulation comprises a PID-regulation device (10). To make up for a rotation speed decrease respectively a sudden rise thereof when an important load is involved or disappears, the integration level of the PID device in the idle filling is increased or decreased skip-wise preferably by an amount which is specific of the load value. The action on the integrator level takes place only during the switching and leads to the direct correction of the load skip effect by immediate and corresponding modification of the regulation signal. Said signal preferably acts through an actuation device (19) such as a twin winding rotary device (20), on a by-pass of a butterfly valve.

Patent DE-3416838-A1 (DE)
Title: Pocket lamp
Inventor: HUERTH GUNDOLF
IPC: F21L4/00
Filed: 1984-05-07
Abstract: The invention relates to a battery-powered pocket lamp of conventional design having an electric switch. In order for the switch no longer to have to be found, it is constructed in the form of an electromagnetic switch that is mounted in the interior of the housing. This switch consists of a hollow cylinder made from electrically non-conductive material, and its two ends are sealed by means of flat, disc-shaped permanent magnets. Arranged in a longitudinally displaceable fashion in the hollow cylinder is a cylindrical soft-iron core having a play between the permanent magnets. Spring contact pieces are fastened on the inside to the end of the hollow cylinder that points in the direction of illumination and run near the wall at a spacing from one another. If the permanent magnet is moved in the frontal direction by a blow on the housing of the pocket lamp and if the permanent magnet adheres to the soft-iron core located there, the spring contact pieces are simultaneously brought into contact with one another and the pocket lamp is switched on. For switching-off purposes, the soft-iron core is released by a blow on the opposite side. It then adheres to the other permanent magnet. The circuit to the incandescent lamp is then broken.

Patent DE-3426983-A1 (DE)
Title: Working cylinder with rolling seal for the high-pressure and low-pressure range
Inventor: NEUHAUS HERMANN ING GRAD
IPC: F16J3/06
Filed: 1984-07-21
Abstract: 1.) Designation of the invention: working cylinder with rolling seal for the high-pressure and low-pressure range. 2.) Technical field: hydraulics, pneumatics, vacuum technology and their sealing technology. 3.) Technical problem: in working cylinders with low piston speeds, relatively high leakage losses develop in the case of the previous sealing technology, which leakage losses allow the hydraulic or pneumatic efficiency to drop to a considerable extent. 4.) Solution to the problem: the gap between piston and cylinder and on the other hand between cylinder and piston rod is sealed off leak-free by a rolling seal. The cylinder with rolling seal consists essentially of a rolling seal and the piston with the piston rod. The rolling seal in turn consists of a foil and a number of spring wires which are uniformly distributed over the periphery of the rolling seal. The cylinder and the piston or the piston rod contain guide grooves in the direction of movement of the piston for guiding the spring wires, which surround the outer periphery of the foil as viewed in the direction of movement of the piston. The rolling-up and unrolling of the rolling seal is effected by the reciprocating movement of the piston. During the rolling-up, the foil of the rolling seal is transferred from its outside diameter to the inside diameter. <IMAGE>
