Patent DE-3818668-A1 (DE)
Title: Rotation-prevention means for screws
IPC: F16B39/34
Filed: 1988-06-01
Abstract: The invention proposes a rotation-prevention means for screws, in particular for clamping and adjusting screws in reamers, which prevents inadvertent loosening of a screw, even under the influence of high forces and strong vibrations. For this purpose, at least one elastic element (6) is introduced into the body (2), in which the screw is inserted, such that it enters into frictional engagement with the screw. The elastic element (6) is inserted into a bore which runs essentially parallel to the through-passage hole (1) in the body (2) and intersects the circumference line of a cutout (4) for the screw head. It can also be introduced into a bore (53) which has been made in the base of the cutout (4). Bores (54, 55), which intersect the side wall of the cutout (4) or the transition region between side wall and base of the cutout (4), are also possible. Depending on the case in hand, one or more bores for elastic elements (6) are provided. <IMAGE>

Title: Method and device for non-live remote control of a switch in an electrical circuit, and an electrical plug connector for this purpose
Inventor: WASCHEK BERND
IPC: H01H33/42
Filed: 1988-07-18
Abstract: The invention creates a contact pair (70, 80; 71, 81), for example a plug connection consisting of a plug and socket, in the case of which that contact (81), for example the plug socket, which is on the supply side is also live only when the contact is made, that is to say, for example, the plug (70) has been inserted into the socket (80). This is achieved by the insertion process (S) enabling light to flow in an optical fibre (4). In this case, light (2) is continuously applied to the optical fibre (4, 6) from one side (8). Making it possible for the light to flow allows the light to act via a second part (14) of the optical fibre (4) on a light-sensitive switch (22) so that the switch closes. The switch is connected between the electrical power source (24) and the contact (81) on the supply side. When the (plug) connection is released, the light flow is interrupted and the switch (22) isolates the plug socket from the electrical power source. <IMAGE>

Title: Method of manufacturing precisely plane-parallel bricks
Inventor: RIMMELE RAIMUND
IPC: B28B11/08
Filed: 1988-12-23
Abstract: A method of manufacturing bricks with precisely plane-parallel outer surfaces for masonry construction is rationalised by the dried unfired bricks being surface-ground and only fired subsequently. Diamond-coated or corundum-coated grinding rings in particular are suitable as grinding tools. However, a corresponding working with hard metal-coated milling rings is also advantageous. In order to avoid changes in shape during firing, argillaceous clays or correspondingly low-vibration clays are used.
