Title: Programmed HF channel selection for vehicle radio stations - minimises same channel interference and includes relay stations with memory bank with inhibiting circuits
Inventor: BRAAK DIRK JOHAN DIPL ING
IPC: H04B7/26
Filed: 1979-09-13
Abstract: The vehicle radio communication system uses a number of HF transmission channels in a regional system comprising a multiplicity of operating zones each having its transmitter/ receiver relaying station. Since it is always possible experimentally to ascertain which of the zones are particularly prone to overlap when communication occurs in them on the same channel and/or on a particular frequency within the choices available, the vehicle equipment or the various relay stations are fitted with a memory bank associated with inhibiting circuits which prevent an operator from using a certain communication channels when neighbouring zones happen to use these channels, and which at the same time frees other channels for selection. This system, therefore, reduces same-channel interference to a minimum.

Title: Device for punctiform measurement of the distance of the boundary surfaces of objects, in particular those in human and veterinary medicine
Inventor: BLUECHER UWE DIPL ING
IPC: A61B5/107
Filed: 1981-01-27
Abstract: The invention relates to a device for punctiform measurement of the distance of the boundary surfaces of objects, in particular those in human or veterinary medicine. Its object is to construct such a device so that it requires for the purpose of accurate measurement of the punctiform separation of the boundary surfaces only two probes but no permanent field, the aim being for the measurement results to be invariant with respect to possible rotary and tilting movements of the probes relative to one another. Furthermore, the device according to the invention is also intended to provide a reliable display of distances greater than the distances so far capable of display by means of other electric or electromechanical devices. This object is achieved by a receiver probe which is to be mounted on a boundary surface and each of whose magnetic dipoles contains in the form of three inductors aligned to be mutually perpendicular, the inductors of the receiver probe generating corresponding voltages, the level of which serves as a measure of the boundary surface distance and is evaluated via a programmed computer and displayed. <IMAGE>

Title: Bicycle light system
IPC: B62J6/00
Filed: 1981-02-21
Abstract: The invention relates to a bicycle light system with preferably two galvanic elements and cells which are connected in series and which output an electrical voltage to at least one load. In order to extend the service life of the elements or cells whilst simultaneously maintaining a predetermined minimum value, it is proposed that when the voltage which is output and/or the current flowing across the load drops below at least one predetermined minimum value, at least one further element or cell is connected in series with the aforesaid elements or cells. For this purpose, it is advantageous to provide a reference unit and a control unit in order to carry out the indicated connection into the circuit by means of suitable switching means. If discrete electronic components are used, a Zener diode is advantageously provided as a reference and control unit. The electronics may of course also be realised using integrated circuit technology or also by means of microprocessors. By means of a special switching electronics, the dropping below the predetermined minimum value can also be indicated by a signal. In addition, the switching over to a generator, in particular a bicycle dynamo, is proposed. <IMAGE>

Title: Element for supporting floor panels or the like
Inventor: GERHARD LUTZ
IPC: E04F15/024
Filed: 1981-03-19
Abstract: The cross-shaped element for supporting purposes is provided in order to prop up, for example, large-surface-area floor panels at their borders. The supporting element (14) comprises two cross-type beams (16, 18) which are designed with channels (20, 22) on their upper side. These channels (20, 22) are closed off at their ends by walls (24, 26) and are provided with lips (28, 30) on the longitudinal borders. The panels (10, 12) rest on these lips, which consist, for example, of rubber, as a result of which the channels (20, 22) are sealed. In the centre of the supporting element there is provided a pipe cross (32) which has a small pipe (34) in its centre. Through this small pipe, which extends upwards in the joint (36) beween the panels (10, 12), rigid foam (40) can be pressed into the channels (20, 22), which foam is distributed uniformly, by the pipe cross (52), in the supporting element. After the rigid foam has hardened, the panels are supported on the resulting, more or less flexible buffers. Consequently, the panels are mounted in a manner which is favourable in terms of statics and, moreover, good sound insulation is achieved between panels and underlying floor surface on which the supporting element rests by means of its underside provided with hollow webs. <IMAGE>
