Patent DE-3439789-A1 (DE)
Inventor: BLOMBERG LOTHAR
IPC: H04B3/56
Filed: 1984-10-31
Abstract: In a mains-type house-line or house-communication system operating by the dialogue method, the number of connectable transmission/receiving sets should be as large as possible. This can be achieved if the receiving circuit of a transmission/receiving set requires only a small part of the transmission power emitted. According to the invention, in synchronisation with the switching of the transmission from transmission to reception and vice-versa, a switching is effected of the coupling impedance linked with the mains line. This is designed is such a way that a lower-ohm transmission output impedance and a higher-ohm receiving input impedance is produced. The circuit arrangement developed for implementation of the process is so designed that a repeater (Ü1) couples both a transmission circuit (1) and also a reception circuit (2) to the leads of a network. Connected in series with the secondary winding (W2) of the repeater (Ü1) is a controllable switch (T3) which is short-circuited during the transmission mode and thus is low-ohmic, and during the receiving mode is open and thus high-ohmic.

Patent DE-3512112-A1 (DE)
Title: Spring tackle block
Inventor: HEINEMANN ALBERT
IPC: B66D3/18
Filed: 1985-04-03
Abstract: A spring tackle block (1) with rope tackle which can be unwound from a rope drum (5) against the force of a spiral leaf spring (6) contains a shaft (4) on which the rope drum (5) is rotatably mounted and on which the spring (6) acts with its inner end (6a). The outer end (6b) of the spring (6) acts on the rope drum (5). The carrying force of the spring tackle block (1) can be changed at the shaft (4) by rotating the shaft (4) and thus changing the preloading of the spring (6). In order to at the same time prevent an excessive tension force on the spring (6) or excessive relaxation of the spring (6), the spring (6) is connected to the shaft drive via at least one free-wheel effective in one direction of rotation, namely a slip clutch (9) and/or a free-wheel (11). Consequently, when a maximum permissible force is reached when changing the tension force of the spring (6), an increase in the action of force on the spring is prevented. <IMAGE>

Title: Contact arrangement having contacts between which soft, permanently elastic, non-conductive material is located in order to produce restoring forces and for protection of the contact zones against environmental influences, and which contacts penetrate this material during operation
Inventor: LAZIC CORNELIA
IPC: H01H1/64
Filed: 1985-08-13
Abstract: In order to produce a contact arrangement which is protected against environmental influences, a plurality of contact parts are arranged at a short distance from a contact surface and are connected by means of a conductive layer. The intermediate space between the contact parts and the contact surface is filled with an insulating layer consisting of permanently elastic, soft, non-conductive material which is penetrated by the contact parts during operation of the contact arrangement. If the conductive layer is produced in expedient form as a resistance layer and is provided with current connections, the contact device can also be used as a voltage or current control. The contact parts need be arranged only in special cases and can otherwise be distributed in an uncontrolled manner over the contact surface. The shapes of the contact parts can also be irregular. For example, metal chips or metal powder of suitable grain size can be used. The contact arrangement is completed by a force-transmitting element, in the form of film, and, if required, by a force-distributing element.

Patent DE-3540173-A1 (DE)
Title: Method for generating basic keys for the encrypted transmission of information
Inventor: KETTERLING HANS-PETER DIPL ING
IPC: H04K1/00
Filed: 1985-11-13
Abstract: A method is proposed which serves to generate basic keys for the encrypted transmission of information. The method is intended to offer a certain security against unauthorised decryption during the transmission of information. For this purpose, the basic keys are derived through mathematical combination from an invariable individual code word of the respective transmitter and an invariable individual code word of the receiver which is sought by the transmitter. Since the transmitter normally always establishes contact with different receivers, the basic keys will differ in every new transmission from the previous basic key. In a radiotelephone network, the code words preferably correspond to the two or more digit telephone numbers of calling and called radio stations.
