Patent DE-2947151-A1 (DE)
Title: Cool air blower for oven switchgear compartment - has two temp. sensitive switches controlling speed during heating and cooling phases of oven
Inventor: NITZINGER KARL
IPC: H05B3/00
Filed: 1979-11-22
Abstract: The main oven switch (8) closes the power supply circuit to a series resistor (14) and the blower drive motor (M). A first temperature sensitive switch (16) shunts the switch (8) and cuts in at 50 deg.C. The motor runs then at a speed of 1500 rev/min. At a temperature of 55-60 deg.C, a second similar switch (17) shunts the resistor and the motor runs at its full speed of 2300 rev/min. The circuitry for the drive of the blower is based on running the motor at different speeds by one or two temperature sensitive switches, depending on whether the oven is used for normal baking duties or for a pyrolytic self-cleaning cycle. This effectively reduces the noise emitted by the blower to a minimum and saves energy by a step-by-step speed control during both the heating and the cooling cycle.

Title: Demodulator for quadrature modulated and digitalised colour TV signal - has filter for removing residual colour carrier when picture moves
Inventor: STENGER LUDWIG DR ING
IPC: H04N9/78
Filed: 1980-02-28
Abstract: The circuit for demodulating a quadrature modulated and digitalised colour television signal has an inter frame comb filter with a delay section (1) having a delay time of at least one image element. This is between an adding stage (2) for the luminance channel and a subtracting stage (3) for the chrominance channel. An intraframe comb filter has a delay device (5) with a delay time of at least one line. A detector gives a switching signal for inter frame and intraframe demodulation when the image moves. This has a subtracting stage (6) for an intraframe comb filter for the luminance channel, which separates the residual colour carrier when the image moves. A bandpass (8) filters out this residual colour carrier. An envelope curve modulator has a gate pulse generator (9) for converting this residual colour carrier from inter frame to intraframe demodulation.

Patent DE-3032376-A1 (DE)
Title: Superconductive transmission line - with insulating or non conductive tubes and thin metallic films for electrostatic power transmission
Inventor: HANSCHMANN HORST
IPC: H01B12/00
Filed: 1980-08-28
Abstract: Conductive wires and cable for transmission lines are produced from non-conductors and insulators by applying to a non-conductive wire (glass fibre) or to a metal tube with a vacuum deposited silicon layer which has superconductive properties, an insulating layer (ceramic lacquer) which is coated by an electrolytically applied metal film. Another insulating (plastic) layer follows. A band generator supplies a high tension via capacitors to the transmission line and drives the electrons to the cable surface. A coolant circulates through the cable, if tubular, to take advantage of the superconductivity. This saves metals such as copper which are in short supply and are costly and reduces the energy losses due to the Joule effect in transmission lines. Based on an electrostatic enfluence machine where electrons are induced on an insulating glass disc, the new cables consist of insulators such as two tubes which have thin metallic coatings. The inner tube can be an insulating layer over a thin copper or aluminium wire or tube. Electronic control systems keep the positive and negative charges of the outer tube constant. Moderately low temperatures suffice to produce full superconductivity and compensate for losses due to the Joule effect.
Patent DE-3033350-A1 (DE)
Inventor: BERNEY JEAN-CLAUDE
IPC: H02P8/02
Filed: 1980-09-04
Abstract: An electronic timepiece comprises a stepping motor driven by alternating square wave pulses, and a detector circuit for detecting the non-rotation condition of the rotor. The detector circuit is responsive to motor load current and looks for the presence of points A, B or C in the load current waveform curve 3 Fig. 1 which indicates normal rotatable condition. If the rotor has missed a step or the load is excessive such that these points are not detected, the load current being as waveforms curves 1, 2 Fig. 1, the detector circuit output is used to progressively adjust drive pulse duration accordingly as in Fig. 7 arrangement, or to make up for lost steps as in Fig. 6 arrangement. The detector circuit comprises an amplifier 24 including MOS transistors 1, 2 (eg as in Fig. 2) and a capacitor 3. Voltage applied to the amplifier is proportional to and has the same waveform as the motor drive current. <IMAGE>

Title: Trickling filter for sewage clarification - adding oxygen to circulating air and discharging min. of waste air
Inventor: RUDOLPH KARL-ULRICH DIPL ING D
IPC: C02F3/00
Filed: 1980-09-06
Abstract: Sewage is clarified in a trickling filter bed from which only a small pt. of the rising air is discharged to atmos. The major part is circulated after oxygen has been added to it to compensate for its consumption in the reaction space. A control unit automatically adjusts the discharge and the oxygen addn. (as a function of the readings of an oxygen probe). This keeps the amt. of air discharged to the environment (and thereby the bad odours) to a min.

Title: Process for the thermal treatment of fine granular material, especially for producing cement clinker
Inventor: DEUSSNER HERBERT DIPL ING DR
IPC: F27D99/00
Filed: 1981-01-12
Abstract: The proposed process for the thermal treatment of fine granular material, especially for producing cement clinker from raw material is carried out in stages, by means of a preheating stage, a calcining stage, a sintering stage and a cooling stage, heat being supplied from any type of fuel, i.e. heat is supplied from gaseous, liquid or solid fuels both in the calcining stage and in the sintering stage. In a process of this type it is proposed to subdivide the calcining stage into a precalcining stage and into an after-calcining stage, the precalcining stage being heated by the off-gases of the sintering stage and the after-calcining stage being heated by fuel combustion of the gaseous, liquid or solid fuels by means of air. The hot off-gases of the sintering stage are admixed with a reductant and/or a catalyst for the thermal-chemical reaction with nitrose constituents contained in the off-gases, the admixture of the reductant and/or the catalyst being effected between the sintering stage and the precalcining stage. By means of thermal equilibrium decomposition, the nitrogen oxides contained in the off-gases of the sintering stage are considerably reduced, and at the same time said off-gases can be employed, in order to utilise their full exergy, in the preheating and precalcination of the finely granular material employed, for example of the cement raw materials.
Patent DE-3102756-A1 (DE)
Title: Apparatus for the straightening of warped or curved boards
Inventor: VETTER GUENTHER
IPC: E04F21/00
Filed: 1981-01-28
Abstract: The apparatus for the straightening of warped or curved boards, for example of wooden door leaves, is arranged countersunk in the board. It consists of two tension members, for example metal bands, which extend in grooves arranged offset relative to the mid-plane of the board, are fastened at one end to the board and at the other end are drive-connected to a threaded sleeve. The two threaded sleeves, of which one is provided with a right-hand thread and the other with a left-hand thread, are screwed onto a screw having a right-hand and a left-hand thread. As a result of the rotation of the screw in one direction, the threaded sleeves are brought nearer to one another, one tension member being tensioned and the other slackened. In contrast, when the screw is rotated in the other direction, the tension member tensioned in the first direction of rotation is slackened, and vice versa. The board can thus be brought into alignment in its plane simply by the rotation of the screw.

Title: Control device for controlling the transmission ratio of a transmission for a motor vehicle
Inventor: OGUMA TOMIO
IPC: F16H61/02
Filed: 1981-05-14
Abstract: The transmission ratio of a variable speed transmission unit for a motor vehicle is controlled by means of a control device which comprises a hydraulic control servo. The control servo includes a servo drive, which is operated by a line pressure and adjusts the transmission, and a piston slide valve, which is acted upon at one of its ends by a signal pressure, which varies as a function both of a pressure dependent on the throttle opening and of a pressure dependent on the vehicle speed and is applied so as to oppose a spring. The piston slide valve forms a control valve for the pressure medium pressure applied to the servo drive and operating the latter. When the signal pressure on the piston slide valve varies, the servo drive is operated or displaced in a direction such that the transmission ratio is increased or reduced. The signal pressure is generated by a compensating valve as a function of a pressure corresponding to the throttle opening and a pressure, for example the governor pressure, corresponding to the vehicle speed.
