Patent DE-3041594-A1 (DE)
Title: Washing machine with self-cleaning liquor filtration system - in which liquor is pumped upwards through high-level filter
Inventor: KOOS DIETRICH DIPL ING
IPC: B01D29/00
Filed: 1980-11-04
Abstract: A washing machine has a liquor circulation system in which the liquor is pumped upwards through a filter chamber which is above the liquor level in the machine tub, and across the middle of which lies a horizontal filter element. During washing, the circulating pump works intermittently whereby, in the intervals, the liquor in the chambers drains backwards through the filter to dislodge the soil trapped in the filter. The filter may comprise a felt pad held between two mesh screens, or it may consist of a stack of metallic screens of decreasing mesh size. This is a comparatively simple and inexpensive arrangement which improves the washing efficiency and gives economies in power and water consumption.

Title: Generating adjustable, phase-fixed thyristor ignition pulses - comparing max. values of sawtooth voltage flanks with reference voltage
Inventor: GODE DIETER DIPL ING
IPC: H02M1/08
Filed: 1980-12-27
Abstract: The ignition pulses are generated for a grid control set of a polyphase rectifier or inverter with thyristors. The pulses are generated by smoothing the synchronisation mains voltage and generating rectangular pulses corresponding to the frequency of the smoothed mains voltage. Time-linear rising sawtooth voltages are generated, with starting points derived from the rising flanks of the rectangular pulses. A control voltage is compared with the flanks of the sawtooth voltages for deriving of ignition pulses from intersection points of the control voltage with the flanks. The max. values of the flanks of all time-linear rising sawtooth voltage are compared with a single reference voltage. When the latter has been exceeded the sawtooth voltages are reduced to its value, while they are raised to this value when being below the reference voltage.

Title: Forcing frame/forcing house with increased collector effect
Inventor: VETTER HARALD DIPL ING
IPC: A01G9/24
Filed: 1981-04-13
Abstract: The forcing frame/forcing house, according to the invention, with increased collector effect comprises an advantageously heat-insulated box-type framework. A specially shaped acrylic-glass cupola is mounted on said box-type framework. Other cupola materials may also be used. Owing to the special geometry of the cupola, an essentially increased heat supply to the crops in the forcing frame is made possible in conjunction with a reflector which is advantageously adjusted such that the rays of the sun in the spring light the front part of the forcing frame. At the same time, a function element of a latent heat store can be mounted in the cupola in front of the reflector. A roller blind or slats of a slatted blind (if appropriate, thermally/automatically controlled) may be additionally installed beneath the cupola. Owing to the configuration according to the invention, in particular that of the glass cupola of the forcing frame/forcing house, an increase in the temperature in general is achieved, the possibility of installing a latent heat store is produced and measures for protection against the sun are expediently configured. <IMAGE>

Title: Process and apparatus for reducing the content of noxious gases in flue gases by means of atomising absorption
Inventor: KRAGH OLE TEGLHUS
IPC: B01D53/68
Filed: 1981-10-28
Abstract: The invention relates to a process for reducing the content of noxious gases in flue gases by means of atomising absorption, a flue gas being treated in a reaction chamber, which has a flue gas inlet, a distributor centrally located in the chamber and a flue gas outlet, by means of atomisation of a reagent in an aqueous solution or suspension, and the solution or suspension being atomised preferably in the upper, central part of the chamber. To improve the reaction conditions in the reaction chamber, a part of the flue gas is by-passed from the flue gas inlet around the flue gas distributor and blown into the chamber against or along the inside of the walls thereof. In this way, a zone of warm and dry flue gas is formed along the inside of the chamber wall, and this makes it possible to run a central zone of the chamber at a temperature close to the dew point.
Patent DE-3145372-A1 (DE)
Title: Thread-forming device for use in combination with a punching operation
Inventor: HERRMANN WALTER
IPC: B23G3/00
Filed: 1981-11-14
Abstract: The invention relates to a device for producing threads by a punching operation, the tap being inserted before the start of a rotary movement into a core hole provided with recesses corresponding to the cutting lands of the tap. During the subsequent rotation of the tap by one pitch, difficulties arise at the start of the return rotary movement on account of the risk of chips being forced into the thread by the tap. By limiting the rotary travel approximately to the length of the thread-carrying part remaining between two recesses in the core hole, the tap is prevented from coming out of the newly formed thread and the difficulties upon re-insertion are avoided. <IMAGE>

Patent DE-3203477-A1 (DE)
Title: Gas water heater with ignition flame not constantly burning
Inventor: CARDALO HARALD
IPC: F23N5/08
Filed: 1982-02-03
Abstract: Water heating (gas combustion) is controlled, as hitherto, by a diaphragm. For operation of the two gas valves and also the piezo igniter, a special ignition rod is required. At the beginning of the heating process the ignition rod rises, actuates the piezo igniter, opens the ignition valve and closes the circuit between photocells and electromagnets by means of a microswitch, thereby giving rise to the ignition flame. The luminosity due to the ignition flame is received by two photocells mounted on the burner and is converted into electrical voltage. This current is conducted via a microswitch to the two electromagnets mounted on the main valve, which open the latter. After the heating process has ended, the ignition rod is lowered and closes the ignition gas valve, and the microswitch interrupts the circuit again. The main gas valve is thereby closed. No uncombusted gas can flow out in the event of failure of the piezo igniter.
Patent DE-3204530-A1 (DE)
Title: Worm gearing
Inventor: JUNG HEINZ
IPC: F16H55/22
Filed: 1982-02-10
Abstract: The worm (3) is flexible and comprises a coil, the individual windings of which are interlocked by the formation of raised parts and recesses on the strand-shaped structure from which the coil is wound. On the inside of its curvature, measured at half the height of the worm threads, the worm (3) has a radius (rS) which is greater than the outer radius (rR) of the worm wheel (2), measured at half the height of the worm wheel teeth. In comparison with a worm gearing in which the curvature of the worm is matched exactly to the curvature of the worm wheel, this gives the advantage that the alternating stresses in the material of the coil are reduced. Several worm threads are nevertheless simultaneously in engagement with the worm wheel, with the result that the advantage of a reduction in the specific loading of the worm threads in comparison with a rigid, straight worm is maintained. <IMAGE>
Patent DE-3206042-A1 (DE)
Title: Automatic safety gas heating device
IPC: F23N1/08
Filed: 1982-02-19
Abstract: A valve rod of a gas heating device actuates not only a microswitch but also a disc valve. A pilot burner and a main burner are controlled separately from one another by individual magnet-actuated valves which are connected in series. The disc valve is provided upstream of the pilot burner and between two magnet-actuated valves in order to afford protection against a faulty switch-on position of the microswitch. According to the presence of the pilot flame, a sensor commands an electric control plate to continue or to interrupt the spark generation of an ignition device and also to open or to close the solenoid valve for supply of gas to the main burner. In this manner, the problem of poisoning, which is caused either by malfunction of the microswitch or failure of the valve actuation, can be eliminated. <IMAGE>

Title: Method for regulating a sorption heat pump
Inventor: KANTNER ALEXANDER DR
IPC: F25B30/04
Filed: 1982-02-25
Abstract: The present invention relates to a method for regulating a sorption heat pump with an expeller, condenser, throttle member, evaporator and consumer, in which the pressure or the temperature in the high-pressure part of the sorption heat pump is provided as regulating variable. To take account of influences from the area of the environmental energy in the evaporator, it is expedient also to take account of the heat content, according to temperature and throughput, of the environmental energy source acting on the evaporator. To achieve this aim, it is envisaged that the temperature of the heat source acting on the evaporator is detected as an additional measurable variable, and that the throughput of coolant vapour through the evaporator is adjusted with a change of the temperature of the heat source feeding the evaporator.
