Abstract: In a display, a screen RAM contains a memory location for each pixel. A mapping RAM contains a number of values corresponding to the display intensity range. The mapping RAM is substantially smaller than the screen RAM. A change in the input-output intensity characteristic requires only a change to affected values in the mapping RAM without changing the greater number of locations in the screen RAM corresponding to those affected values.

Abstract: Eyeglass lenses for persons suffering from severe ametropia. The lenses have a convexly shaped object-side front surface (4) and an eye-side rear surface (3) which is aspherically corrected in the central region (6) which comprises at least the main field of view. From this region the rear surface passes into a region in which its meridional inclination approaches the inclination of the front surface. The entire rear surface of the lens is continuously differentiable twice. Such a lens has an appearance which is fully satisfactory esthetically and makes it possible to keep the overall magnification of the system consisting of the eye and the eyeglass lens closer to 1 than in the case of previously known lenses. Aberrations are optimally corrected within a sufficiently large region, and no disturbing discontinuities in the fields of view occur.

Abstract: A production control system is provided, especially for use in a works environment, in which a microsequencer controlled by a Z80 microcomputer board (MUXC) performs continuous high-speed scanning of a multiplicity of operator input devices (OIDs) located at the work stations of individual human operatives. The microsequencer is essentially a single-level pipelined microprocessor communicating with the OIDs via channels and sub-channels, each OID being connected to a respective sub-channel by a single twisted- pair cable. The cable lines are maintained at 24 volts d.c. to supply power to the OID, and the OID, which has a card-reader for reading bar code on cards or tickets passed through it by the operative, transmits data to its sub-channel, and hence the microprocessor, over the same cable by shorting out the two cable lines for short and long pulse periods. The microsequencer checks the validity of each read and responds to the OID to indicate a good read or otherwise - this response is sent in a morse-type code to audio and visual responders in the OID by temporarily reversing the polarity of the same two lines of the communicating cable. The Z80 microcomputer loads microcode into the microsequencer and thereafter supervises the scanning and data- reception and checking functions. Good reads are stored in short-term storage in the MUXC and can be transmitted to up-date the data base of a host minicomputer. Serial link communication between the MUXC and the host computer is via channels incorporating adapters having optical isolating devices to ensure compatibility and satisfactory transmission over distances in a factory environment.

Abstract: A preloaded electrical connecting device (10) for use with closely spaced elongated conductors (64) which lie essentially in the same plane is disclosed. The device (10) is comprised of an insulated housing (12) having a plurality of contact terminal receiving cavities (22) therein and having one or more electrical contact terminals (26) therein. The terminal (26) is a flat one piece stamped sheet metal member having elongated connector means (27) at one end. The connecting means has first and second jaw members (32,34) and a throat portion (36). The jaw members (32, 34) have spaced apart free ends (38, 40). In the assembled device, a portion of the free end (38) of the first jaw member (32) extends outwardly from the housing (12). Upon placing the conductor (64) between the first and second jaw members (32,34) and applying a deforming force to the free end (38) of the first jaw member (32), the portion (38) is moved into the housing (12) until the end (38) is flush with the housing (12). As the jaw portion is moved into the housing, the jaw member (32) is moved into clamping engagement with the conductor (64) and the second jaw member (34).

Abstract: In a filter having a housing with an inflow and an outflow for a medium which is to be filtered, a filter insert which subdivides the interior of the housing into two part spaces, of which the first communicates with the inflow and the second with the outflow, and a displaceably mounted valve body to which medium from the first part space on the one hand and medium from the second part space on the other hand can be admitted and which is displaceable out of an initial position against the action of a resilient force accumulator when a defined differential pressure of the media in the two part spaces is exceeded, it is proposed, in order to prevent an unduly high differential pressure between the first and second part spaces, to assign to the valve body a valve seat which is located in the flow path from the second part space to the outflow, and to lift the valve body in the initial position off the valve seat, whereas it is moved against the latter when the differential pressure of the media in the two part spaces increases. <IMAGE>

Abstract: In the method for heating room air, in particular for apartment dwellings, using a heat source which consumes fossil fuels, a water heat accumulator and a heat exchanger device in the waste gas flow of the heat source, an outgoing air heat exchanger being superposed above the heat exchanger, for the room air, and the outside air to be heated being conducted first through the outgoing air heat exchanger and then through the waste gas heat exchanger and being heated in two stages, a further energy optimisation is to be achieved. This is achieved in that the outgoing air, after leaving the first heat exchanger for the outside air, is fed into the combustion chamber of the heat source and, with the waste gas from the heat source, is supplied to the second heat exchanger for the outside air and is carried off as discharge air together with these waste gases. <IMAGE>
