Patent DE-3210077-A1 (DE)
Title: Radiotelephone system
Inventor: DALLMANN HORST
IPC: H04W74/00
Filed: 1982-03-19
Abstract: A radiotelephone system is proposed with a plurality of fixed (13 to 16) and a plurality of mobile transceiver stations (11), where the fixed stations (13 to 16) are connected via a mobile switching centre (25) to the telephone network (26). The mobile stations (11) have an automatic cyclic scanning device for the radio channels (K1 to K4) to search for calls. When a call is made to a mobile station (11), stop signals are transmitted via all fixed stations (13 to 16) or channels (K1 to K4) for the scanning devices of the mobile stations (11), in each case followed by selective call signals for a mobile station (11). If a radio link is then established, preferably following the transmission of an acknowledgement signal by the called mobile station, pilot tones are transmitted via all the free radio channels for their identification by the remaining mobile stations, which tones are stored in the mobile stations (11). As a result, a specific mobile station is reached quickly and reliably on the one hand and on the other hand a call is prevented in the inverse case from being unsuccessfully set up from a mobile station (11) on an occupied channel. The hardware cost of this arrangement is kept very low due to multiple use of circuits. <IMAGE>

Title: Process and apparatus for concentration and filtration of suspensions
Inventor: SEKOULOV IVAN PROF DR ING
IPC: B01D24/08
Filed: 1982-04-20
Abstract: In the concentration and separation of suspended matter from liquids, in particular in waste water technology, long filter times with low pressure drops and effective back washing are desirable. For this purpose, an apparatus is proposed according to the "cross-flow" principle of filtration, in which the filter surface is constructed vertically; a cross flow to the filter flow is produced by aeration or mechanically. In addition, concentrated suspensions are eliminated from the system from the filter prechamber in a part-stream, considerably easing the back washing. <IMAGE>

Abstract: The invention relates to a driving shield with a working chamber which is sealed off to the rear in the shield front part by a transverse wall and is defined to the front towards the heading face by a scraping disc and in which the scraping disc, for peeling off the in-situ earth material at the heading face, is arranged in such a way as to be rotatable in both directions in a supporting liquid under pressure and from which the excavated earth material, partly mixed with the supporting liquid, can be fed via a feed hopper to a screw conveyor, the rear discharge of which is arranged outside the working chamber. In order to be able to dispense with an expensive separating plant for separating the supporting liquid and earth material and to achieve energy-saving removal of the earth material to be deposited on a dump in a simple manner, the discharge of the screw conveyor is arranged in a second shield chamber which is sealed off from the rear part of the shield by a chamber wall and to which compressed air is admitted which regulates the pressure of the supporting liquid in the working chamber. In the shield chamber, the earth material mixed with supporting liquid is fed to a screening device in which the supporting liquid is separated to the greatest extent and is also fed to a pump arranged at the base of the shield chamber and leading with its pressure line into the working chamber. The earth material, still only slightly mixed with supporting liquid and therefore having a pasty consistency, is ... to a compactor worm ... Original abstract incomplete.

Patent DE-3434813-A1 (DE)
Title: Thermoelectric oscillation generator
Inventor: KICK THOMAS H
IPC: H02K35/02
Filed: 1984-09-22
Abstract: Conventional methods for converting heat energy into electrical energy, which thus do not fall into the field of semiconductor technology, require a considerable cost in the mechanical field. This cost can, however, be considerably reduced by limiting to linear movements; this results in an economical and cost-effective construction. With respect to the environmentally friendly utilisation of heat energy at relatively low temperatures, for example solar energy, the method of operation of the thermoelectric oscillation generator is based on the known operating principles of closed hot-air machines. However, in order to control the frequency and to optimise the efficiency, an electromagnetically controlled regulator is, however, used instead of the otherwise usual displacement device.
Patent DE-3435421-A1 (DE)
Title: Decorative frame having a plurality of flat frame elements joined together
Inventor: HAUSCHOPP NORBERT
IPC: A47G1/06
Filed: 1984-09-27
Abstract: The invention relates to a decorative frame for framing one or more illustrative or three-dimensional objects. The essence of the invention lies in the fact that the decorative frame consists of a multiplicity of frame elements which can be pivoted towards one another in a plane which is common to all frame elements. This results in the advantage that framed areas of different size and shape can be formed. Since the individual frame elements are of board-type construction, they can be used on both sides. While one side of the frame can be provided with symbols and lettering which refers to the framed object, the other side of the frame has receiving devices for drinking vessels. As a result of the special construction of the joints, an articulated board with substantially stiff joints can be formed from the frame. <IMAGE>
