Title: Cam-controlled coding switch
Inventor: THEN GEBHARD
IPC: H01H19/62
Filed: 1983-03-03
Abstract: The invention describes a cam-controlled coding switch which is equipped with a stepping switching mechanism. With the aid of a rotor of the stepping switching mechanism, which is connected to at least one cam plate, contact elements which are sprung by means of the cam plate interact with fixed-position contacts in the sense of alternately opening or closing. In order now to be able to produce the coding switch easily and cost-effectively it is proposed to fix the rotor, which is produced from plastic, with its sleeve-shaped projection by means of flanging in a printed circuit, such that it can rotate. In this case, the contact elements are inserted into openings in the printed circuit board and are soldered to the associated conductor tracks, the free ends of the contact elements interacting with the pin-shaped, fixed-position contacts.

Patent DE-3334172-A1 (DE)
Title: Method of correcting continuation addresses
Inventor: MAIER REINHARD
IPC: G06F7/24
Filed: 1983-09-21
Abstract: Memories of data processing installations are often organised in such a way that the elements (EL1, EL2...EL5) of a first memory (SP1) contain continuation addresses which refer to elements (EM1, EM2...EM5) of a second memory (SP2). If the content of this second memory is resorted, the continuation addresses are no longer correct and have to be corrected. For this purpose, the elements (EM1, EM2...EM5) of the memory (SP2) include an additional field (FL3), into which reference addresses are entered during any resorting. These reference addresses indicate into which element the information has been transferred during resorting. A search operation is therefore not required and, with the aid of the reference addresses, the continuation addresses can be corrected. The invention is used in data processing installations.

Title: Device for applying the sand coating to tennis courts
Inventor: ARZT ALWIN
IPC: E01C19/20
Filed: 1984-02-25
Abstract: A device for applying the sand coating to tennis courts is proposed, the sand being arranged in a downwardly tapering storage container with a trough-shaped extension on a self-propelled vehicle. The sand falls through one or more openings onto at least one rotating scattering plate and is thrown radially outwards. For supplying the sand from the trough-shaped extension to the storage container and the outlet openings, there is provided in the likewise tapering part of the extension an essentially horizontally arranged worm conveyor. In order to prevent clumping and compacting of the sand, the storage container and its extension have a depth which is small in comparison to its width. To reduce the width of the vehicle, the wheels are arranged essentially inside the lateral limit line of the storage container. As a result, the vehicle remains movable and can easily be brought through narrow openings onto the tennis court.
