Patent DE-3036124-A1 (DE)
Title: Heat pump heat recovery open circuit - uses expansion valves and compressors to recycle steam to higher temp. chamber in multichamber system
Inventor: BRAY STEVEN CHRISTOPHER
IPC: F25B30/00
Filed: 1980-09-25
Abstract: The heat recovery circuit includes a system of pairs of mixing chambers, e.g. two pairs (1,4). The two pairs are formed by three chambers (2,3,5) operating at successively lower temperatures. Steam entering the highest temperature chamber (2) through an expansion valve (13) is separated into steam and water, and the steam is treated by a compressor (17). The liquid is discharged through a connecting line (8) and another expansion valve (9) into the next chamber (3) operating at a lower temperature. Due to the expansion, the steam obtained is treated by a second compressor (11) to give superheated steam, which is fed through a line (10) back to the first chamber to be passed to the first compressor. The remaining fluid can be recycled, and similarly, steam can be passed to the third chamber (5) with a further compressor (11) for further expansion and compression, recycling the steam, and separating the water, which is finally discharged from the lowest temperature chamber (5) by a pump (20).

Title: Arrangement for controlling the program of a data processing system with stored microprogram
Inventor: FISCHER DIETER DR ING
IPC: G06F9/22
Filed: 1981-06-16
Abstract: The proposed arrangement of the assemblies and signal paths of a microprogram controller is intended for microprogram-controlled arithmetic units in data processing systems. It brings advantages, particularly in such systems, to calculating the higher mathematical functions via a series expansion as polynomials with constant coefficients. It is the object of the invention to create such an arrangement which eliminates the defects of known technical solutions with little technical complexity. It should be possible to insert this arrangement easily into existing arrangements for controlling the program of a data processing system with stored microprogram for calculating mathematical expressions having at least one constant. According to the invention, the object is achieved by the fact that outputs of the control unit which are intended for this purpose or are temporarily not needed and are switched to multiple use by the control unit are connected via a connection according to the invention and a multiplexer controlled by the control unit either via the data input register or directly to the arithmetic-logic unit and the signals of this connection are processed as data in the arithmetic-logic unit.

Title: Passive electrooptical display device having a reflector
Inventor: GLAUBITZ WERNER
IPC: G02F1/13357
Filed: 1981-08-18
Abstract: It is proposed to configure the supplementary illumination of a display in the following way: located upstream of the actual display cell is a light-conducting film (13) which extends parallel to the plane of the cell and is composed of alternately juxtaposed lamellae (14) and intermediate layers (16). In common with the intermediate layers, the lamellae consist of light-transmitting materials of varying refractive index, and the interfaces (17) between these strips are inclined to the plane of the cell. On one of its narrow sides, the film receives artificial light which upon passing through the light-conducting film (13) on each of the abovementioned interfaces (17) is partially refracted and partially reflected - towards the cell. Since the light beams are somewhat attenuated at each interface, the reflected component should increase with each reflection given a particularly uniform illumination of the display field. The proposed solution is preferably applied in liquid crystal displays, and is always useful when there is a requirement for a compact display which can also be read off effectively from oblique directions. <IMAGE>
