Title: Internal telephone system - using four wire connection in which call between two extensions also blocks any other from listening in
Inventor: HEPPNER MANFRED
IPC: H04M9/00
Filed: 1980-09-30
Abstract: The private multiple extension telephone system employs a central exchange as a control and power supply unit. Two cores of the connecting cable are used for both power and speech, the remaining two cores for signalling and also for interlocking. When the speech circuits are energised, which follows the selection of an extension and subsequent acceptance by that extension of the call, a lock-out relay picks up which blocks are being used by the participating extensions to avoid selection by a third party. This can be achieved by transistor switching of power supplies in conjunction with electromagnetically operated relays in the speech circuit.

Title: Resistance heating bar for hot sealing thermoplastics foil - has varying cross section to give uniform temp. distribution
Inventor: TESCH WOLFGANG
IPC: B29C65/22
Filed: 1980-11-04
Abstract: A resistance-heated bar for the hot-sealing of thermoplastics foil in packaging, optionally combined with cutting of the sealed foil, has a cross-section which varies along its length. Preferably, the variation in cross-section is achieved by grinding or milling away certain zones (3) particularly towards the end of the bar, where the resultant grooves may be wder or deeper. The preferred removed zones of material are on the rear face of the bar, opposite to the sealing edge (14). The electrical conductors supplying the bar are pref. of constant cross-section. For the hot-sealing of plastics foil either as a direct wrapping to a package or article, or for joining together the ends of wrapping bands. In a bar of constant cross-section there is always a tendency for excessive heating near the centre. By varying the cross-section in the above manner a more uniform temperature distribution along the bar is acheved, with consequent improved sealing acton and also reducton in the cooling times between successive sealing operatons.

Title: Anti-dazzle headlight system for motor vehicles
Inventor: BRUHN WERNER
IPC: B60Q1/00
Filed: 1981-01-22
Abstract: System in which the dazzling from motor vehicle headlights is controlled electronically by means of a special camera in such a way that only the space above the light sources of oncoming motor vehicles remains excluded from the illumination. The light-sensitive layer of the camera and a disc which is projected forwards by the headlight are divided up into vertical strips which are assigned to one another. Small panels which are located one next to the other in vertical fashion form with their narrow sides the light-sensitive layer of the camera and contain the required circuits. A direct current control controls the displaceable transparency threshold of strip-shaped optoelectrical cells on the projection disc so that above each light source in the region of the headlights a rectangular shadow whose width and height are controlled is produced. The light of the headlight which is not utilised for projection forms the far side parts of the region of illumination of the headlights. Projection disc and lamp can be replaced by a projected light source which is divided up into corresponding strips. If required, the light source can be switched off in rapid succession for imperceptibly short times whilst the camera receives the control signals.

Title: Level switch
Inventor: KOY GUENTHER
IPC: E03F5/22
Filed: 1981-03-14
Abstract: Level switches are used to allow switching operations such as the switching on and off of a pump as a function of the level of a liquid. For this purpose, the level switches have a switching element which is moved by the liquid. In order to guarantee operating points which remain accurate even after a prolonged period in use, the switching element is formed by a diaphragm (22) which is at the bottom end of a hollow cylinder (16) and forms the lower closure of said cylinder (16). Running through the hollow cylinder (16) is a switching linkage (34) which is connected to the diaphragm (22), follows its movement and operates a microswitch (42) for the triggering of the switching operation. Thus only the diaphragm (22) and the tube (16) are exposed to the liquid, while the switching linkage (34) and the switch (42) can be arranged in a completely protected manner. The cylinder (16) can be mounted precisely in a fixed manner, thus ensuring that the diaphragm (22) at the bottom end of the cylinder (16) responds at a precise liquid level when the said liquid rises and presses against the diaphragm (22). The effects which any contaminants in the liquid could have on the operating point are largely eliminated. <IMAGE>
