Patent DE-3806003-A1 (DE)
Title: Waveguide coupling-out pin (rod) for a domestic microwave appliance
Inventor: BEIFUSS WOLFGANG DIPL ING
IPC: H05B6/72
Filed: 1988-02-25
Abstract: The invention relates to a waveguide coupling-out pin which injects the microwave energy from a waveguide into a cooking space. The waveguide coupling-out pin is characterised in that it has a low-reflection coupling-pin geometry which is matched in a microwave-specific manner and consists of a coupling pin, a coupling-pin neck and a coupling-pin cylinder, and in that, taking into account maximum microwave-energy injection into the cooking space, the waveguide coupling-out pin which is suitable to accommodate an additional microwave-emission device is guided into the cooking space at the centre of the waveguide, the coupling pin being arranged approximately at up to half the height of the waveguide. <IMAGE>
Patent DE-3806157-A1 (DE)
Title: Heat-exchanging ventilation wall system
Inventor: WEBER HILAR
IPC: F24F5/00
Filed: 1988-02-26
Abstract: The innovation relates to a heat-exchanging ventilation wall system which affords considerable advantages in connection with traditionally constructed external walls of old and new buildings in respect of room-air improvement, energy saving and maintenance of the value of the building. This is achieved in that heat-exchange elements according to the innovation are fitted between a room-side wall cladding and a core wall, behind which heat-exchange elements an additional air gap is situated. Room exhaust air flows in them from the inside outwards and supply air from the outside inwards. On the way to the room, the supply air absorbs room-air heat exchanged in the air gap, inflowing transmission heat and some of the temporarily stored facade heat and transports these with it into the room. In addition, the rear warming of the wall covering with exhaust-air heat also contributes to energy saving. The moisture condensate produced during the exchange of the exhaust-air heat to the supply air within the heat exchanger is captured at the bottom of the heat exchanger in a manner which does not involve damage. By the heating of the supply air in the air gap, the latter can additionally absorb moisture from the core wall, as a result of which the wall structure remains permanently dry.
Patent DE-3807020-A1 (DE)
Title: Liquid crystal display having clock-controlled disconnection
Inventor: BERNECKER OTTO DR
IPC: G09G3/36
Filed: 1988-03-04
Abstract: Liquid crystal displays are driven by a driver circuit, usually using a multiplex method. For generating the driver signals a multiplicity of different voltage levels is necessary which are generated by voltage multiplier circuits. The driver circuit and the voltage multiplier circuit are connected to a clock generator to ensure, inter alia, a regular polarity change-over at the electrodes of the liquid crystal display. To protect the liquid crystals from being loaded with a direct current, for example in the case of a failure of the clock generator, according to the invention there is provided a means which switches off the driver stage when the difference between the basis voltage level and a voltage level generated by the voltage multiplier circuit falls below a predetermined value.

Title: Ultrasonic tomography device
Inventor: NEWERLA KLAUS
IPC: G01S15/89
Filed: 1988-08-01
Abstract: For producing a tomographic ultrasonic sectional image a plurality of B scans have to be superposed which were obtained from different angular directions. These different aspect angles are implemented by means of a plurality of linear ultrasonic transducer arrays (2i) which are arranged around an object under examination (6) along an arc (4) of a circle and are driven one after the other with respect to time. Before the superposition can take place the B scans which are present in each case in relative coordinates (xi, yi) have to be recalculated (converted) into the stationary coordinate system (x, y) of a monitor (10). According to the invention, an analog calculation circuit (20) is provided for this coordinate transformation and a monitor (10) having separate inputs for brightness (z) and to the horizontal (line) deflection (x) and vertical deflection (y) is provided for the graphical representation. As a result, the time needed for calculating the coordinate transformation becomes virtually negligible and the real-time graphical presentation of tomographic ultrasonic sectional images becomes possible on a monitor (18). <IMAGE>

Patent DE-3903066-A1 (DE)
Inventor: GRIFFITH SCOTT I
IPC: G06F12/08
Filed: 1989-02-02
Abstract: An improved memory architecture includes a processor (CPU) 30 coupled over a bus 33 to a plurality of dynamic random access memory (DRAM) banks 32, 34. A cache memory 36, 38 is coupled between each of the DRAM banks and the bus. Each cache includes a static memory for data which is a subset of the data in its respective DRAM. An address provided by the CPU is composed of a base address and tag address. A bus interface controller (BC) within each cache compares the base address and ignores it if it falls outside the range of addresses stored within its DRAM. If it fails within the range, and the processor is executing a READ operation, the tag address is compared to a plurality of tags representing data in the cache. If a match occurs, then cache control logic initiates a READ cycle to the cache and provides the data to the CPU. In the event no match is found, the logic initiates a DRAM access cycle. A tag address within the cache is then randomly chosen and the data read from the DRAM is provided to the processor and stored in the cache at the location of the randomly chosen tag. The previous data corresponding to the randomly chosen tag is stored in the DRAM if a modify bit indicates that it represents updated data not previously stored in the DRAM. Similar operations are provided in the case of a WRITE processor command, whereby data to be written is stored in the cache and a randomly chosen tag address is deleted and the DRAM updated if required. <IMAGE>

Title: Device for frictionally driving an object, in particular a drum
Inventor: GERLACH KAY DIPL ING
IPC: F16H13/04
Filed: 1989-02-22
Abstract: Device for frictionally driving an object, in particular a drum (10).   Devices of this type, namely so-called friction wheel drives, by nature permit only a limited power transmission. Moreover, positional deviations of the object to be driven influence the driving properties. The invention is concerned with eliminating this disadvantage and permitting greater driving forces. According to the invention, the device has a contact wheel (18) which is assigned to a driving wheel (17) and is coupled to the driving wheel (17) in such a way that it exerts on the driving wheel (17) a reaction force directed against the object (drum 10) to be driven. The device is particularly suitable as a friction wheel drive for rotating drums (10) with fixed pivot (11) or floating mounting. <IMAGE>

Patent DE-3913180-A1 (DE)
Inventor: NAKAHATA MINORU
IPC: G08B21/00
Filed: 1989-04-21
Abstract: Variation of a line current resulting from malfunction such as short-circuit or ground fault is detected and when the current exceeds a predetermined value, an indicator 21, 22 indicates "malfunction". The indication is maintained with latch relays 23, 30 and a capacitor 50 is charged. When the terminal voltage of the capacitor 50 exceeds the Zener voltage of a Zener diode 54 connecting the capacitor with the base of a transistor 55 for activating a reset relay 64, base current for the transistor is supplied from the capacitor 50 through the Zener diode. When the malfunction is restored, the indicator is reset by activation of the reset relay 64, and the Zener diode 54 is short-circuited by one of the contacts 64-3 of the reset relay. Base current is supplied via the contact even when the voltage on capacitor 50 falls below the Zener voltage. A thyristor may be used instead of contacts 64-3. <IMAGE>
