Title: Excrement disposal from medium-sized animal stalls - without pollution by extracting air and washing excrement with activated sludge
Inventor: ASENDORF ERICH DR
IPC: B01D47/02
Filed: 1978-02-22
Abstract: Whilst the air to be vented is being deodorised, the run-off from the floor of small to medium-sized animal rearing stalls, is converted into manure without environmental pollution. In the first of three operations, the air is extracted from the stall, and before going to atmos. it is washed with water contg. activated sludge in a reaction tube in an activating tank. The run-off from the stall is mixed in the reaction tube with the water contg. sludge and is fed with it back to the activating tank. After the activated sludge has been sped. the clarified water is let off to the drains. Finally the stabilised excess sludge i stored for use as long-term fertiliser. Used in undertakings with stalls contg. up to fifty animals, as are found on the outskirts of townships. The units can be installed compactly and work highly efficiently.
Patent DE-2807999-A1 (DE)
Title: Short circuit protection for transistor inverter - uses current rise limiting choke shunted by diode for separate suppression control
Inventor: BEINHOLD GEORG
IPC: H02H7/122
Filed: 1978-02-23
Abstract: A choke (1) is in series with one line of the supply from a low impedance dc supply to the transistor inverter (WR). This choke is shunted by a diode (n) arranged to conduct in the opposite direction to the supply. The choke limits the rate of rise of fault current whilst the diode suppresses voltage transients due to choke in normal operation. A shunt (a) provides a signal for a control circuit (k) which limits transistor conduction to a preset max. current (I). Galvanic separation (o) is provided in the base connection to the transistor.
Patent DE-2810988-A1 (DE)
Title: Built-up tube drawing die - enables worn parts formed as laminations and segments to be renovated and reused
Inventor: WASSEN JOHANN ING GRAD
IPC: B21C3/14
Filed: 1978-03-10
Abstract: Tube drawing die is composed of a number of laminations with tapered bores. The angle of the taper is the same for all the laminations which are so arranged that all the bores form a common conical surface. The laminations which give the tube its final outside dia. are made of hard metal whilst the other laminations can be of lower grade material. The other laminations can be renovated by re-boring and then used in a different position inside the housing. This feature reduces the amt. of expensive material in the die.

Title: Capacitive blood pressure meter with frequency transducer - has capacitor with parallel plates connected to moving parts
Inventor: BRAMM GUENTHER DIPL ING
IPC: G01L9/12
Filed: 1978-12-12
Abstract: A pressure measurement device, esp for blood, has a pressure sensor in which the position of a first part undergoes a reversible position change w.r.t. a second part during a pressure change. It enables larger adjustments of the device or its evaluation section without sacrificing accuracy. A pressure to frequency transducer contains an RC oscillator with a triggered threshold controlled charge-discharge circuit. The RC element contains a measurement air capacitor with plane parallel electrodes (33, 34). The electrodes (33, 34) are coupled to respective moving parts (27, 28) so that when the parts move w.r.t each other the electrodes move w.r.t each other along their common surface normal direction. The capacitance variation causes a frequency variation used to control an indicator.

Title: Multistage phase demodulation system - has filter converting phase modulation into frequency modulation whose amplitude indicates phase
Inventor: BROOK KEITH REGINALD
IPC: H03H11/12
Filed: 1978-12-18
Abstract: The phase demodulation system has a filter with a specified amplitude/frequency response and arranged so that a frequency modulated signal is derived from the received phase modulated signal from whose amplitude the phase modulation can be obtained directly. The filter consists of a number of stages. One stage is passive low-pass filter whilst the other active high-pass filters. The advantage lies in avoiding large amount of l.f. noise produced in systems that are noticeably sensitive to frequencies lying below the threshold frequency.

Title: Control circuit for three=phase asynchronous motor - stops, starts and brakes motor using only two pairs of antiparallel thyristors
Inventor: SCHOLZ HORST ING GRAD
IPC: H02P3/24
Filed: 1978-12-21
Abstract: The control circuit has two make contacts connected via logic to the inputs of a second control part. The first output of the second control part is connected to the gate of a thyristor in a two-thyristor switch which acts as a braking thyristor. The second output of the second control part is connected to the gate of a thyristor that is in antiseries with the braking thyristor and is assigned as a free-wheeling diode (free-wheeling thyristor) to two stator windings of the motor. The second control part is used for the controlled braking of the motor. The outputs of the second control part, like the outputs of the first control part (on/off switching), are d.c. decoupled from the gates of their respective thyristors.

Title: Swivel seat for train - has lateral movement to secure swivel in locking wedges
Inventor: KOCH LUDWIG
IPC: B60N2/06
Filed: 1979-01-08
Abstract: A swivel mounting for train seats enables passengers to face in either direction. It has the seat frame linked to the support frame by two sets of parallel levers which swing the seat laterally against securing wedges and prevent rattling. The lateral swing also involves a downward action which locks the frames together. The seat is operated by pulling to one side to disengage the wedges and lift it on the levers. The swivel action is then free to turn the seat. On releasing the seat it drops onto the wedges by its weight. A spring loaded locking catch can also be included.

Title: Multifunction alarm unit operated from mains supply - has separate sensors connected by multicore cable, and has alarm cancelling switch
Inventor: GREISINGER ELISABETH
IPC: H02G3/00
Filed: 1979-03-08
Abstract: The alarm unit is intended for connection directly to the mains supply. It comprises an isolating transformer to give reqd. power supplies, an electronic alarm circuit, audible or visible alarm signal, and an alarm cancelling switch. Incoming signals enter through a polarised multipin plug which is also used for power supplies to remote detectors. It may be advantageous to use marshalling boxes for the remote detector leads. The remote detectors may be used to monitor gas leakage, fire, or be part of an intruder alarm. The central unit may also contain a relay for initiating action in response to an alarm, or for giving additional remote indication. The proposed unit allows operation of a number of functions from one central point employing mains power instead of batteries.

Patent DE-2930040-A1 (DE)
Title: Fault correction for integrated A-D converters - uses three-step conversion of three analogue reference voltages of different polarity, applied to converter input
Inventor: SPIESBERGER GERHARD DIPL ING
IPC: H03M1/00
Filed: 1979-07-24
Abstract: Three steps are used for conversion of three analog reference voltages (O1-Un,Up), applied to the input of an A/D converter. At least two of these voltage differ from zero and are of different polarity. These voltages are converted into digital values. The latter are stored in intermediate memories. A computer provides digital fault values (x,yp,yn) from the preset rated values of the three voltages and the digital values from the conversion. At least one fault value serves as measuring voltage (US), supplied to the input of the A/D converter, using the computer for correction of the digital conversion result. One reference voltage may be obtained by short circuiting the input terminals of an integrating amplifier (I). If the process is used in a dual-slope system, the second and third reference voltages are those used for reverse integration.

Title: Hamburger meat slices - prepared from chopped pork, scalded in shaped cases and fried before consumption
Inventor: GRIMM MANFRED
IPC: A23L13/60
Filed: 1979-11-15
Abstract: Meat shapes for use as instant snacks between split rolls are prepared from chopped lean pork which is seasoned and filled into cylindrical cases before scalding. The cases for the chopped meat can be made of natural or synthetic gut of a diameter to suit the desired finished Hamburger. After scalding the filled cases can be dispatched to the eating places where the skin is removed and the slices are cut just before the frying operation. If the mean is not to be fried immediately, it can be stored in ordinary refrigerators. The scalding kills all germs so that the meat need not be stored by deep freezing. No additional spice is needed prior to consumption.
