Patent DE-1913158-B2 (DE)
Title: Microwave receiver with compensated backward mixing - includes local oscillator supplying IF mixer diode and parametric step-up mixer
IPC: H03D9/06
Filed: 1969-03-14
Abstract: The microwave receiver consists of an antenna (1) passing the received signal to a diode mixer (2), whose IF output is passed on to the If amplifier (3) and sampled by a directional coupler (7) for passing back to a pumped parametric step-up mixer (5). The local oscillator (4) supplies both the IF mixer diode and, via a phase shifter (6), the step-up mixer. The mixed IF and local oscillator signal is passed to the IF mixer. The advantage of this arrangement of mixing lies in its increasing sensitivity and reducing noise by compensating for the input mixer's losses due to increased backward mixing.
Patent DE-1957535-B2 (DE)
Title: DC voltage comparator using high gain operational amplifier - has memory function given by simple resistor as positive feedback element
IPC: G01R19/22
Filed: 1969-11-15
Abstract: A d. c. voltage comparator consists of a high-gain operational amplifier with inverting and non-inverting inputs for the voltages being compared. The comparator output voltage depends on the magnitude and sense of the difference between the input voltages. The comparator has inverse feedback networks in each direction which depend on specific voltage difference thresholds and give a zone of high sensitivity for differences below this threshold and a zone of low sensitivity for differences above the threshold. A positive feedback network effective only in the zone of high sensitivity has a degree of positive feedback that is negligibly small compared with the degree of negative feedback in the zone of low sensitivity. The positive feedback network may be a simple resistor between the output and the non-inverting input of the amplifier.
Patent DE-2048499-B2 (DE)
Title: Radio transceiver-microphone combination for theatre - receives UHF radio control signals to alter LF signal amplitude and prevent distortion
IPC: H03G1/02
Filed: 1970-10-02
Abstract: The combination handles a wide dynamic range signal without LF distortion occurring in the microphone's transmitter and without the signal to noise ratio becoming smaller. The microphone also has a receiver for UHF radio control signals which are used to adjust the amplitude of the LF signals being sent by the microphone's transmitter. The amplitude adjusting device consists of a gain-controlled LF amplifier stage whose gain-control input is connected to the output of the receiver. A-ternatively, the device may be a controlled voltage divider, one of whose resistors is a transistor driven by the receiver.

IPC: H02P27/02
Filed: 1990-01-22
Abstract: In the case of controlling AC voltage converters by means of phase control by semiconductor valves (6), the triggering signals must, on the one hand, be sufficiently long to ensure reliable triggering and, on the other hand, sufficiently short to avoid an overload of triggering amplifiers (12). The invention therefore provides for the use of triggering signals (ZZ) with a variable time length, which end at least approximately when the current flowing in the triggered phase increases again. Devices for carrying out the method are also specified.

Abstract: A protective layer of BaSO4 or BaSO4 mixed with SiO2 is applied in suspension to the inner surface of the glass discharge tube or envelope of a gas discharge lamp of the metal vapour type. The protective layer prevents contact, e.g., of mercury in the discharge chamber with amalgam-forming substances present in the glass surface of the lamp discharge tube. In addition, the crystals of the protective layer re-reflect shortwave ultraviolet radiation back to the layer of luminescent substance, thereby to generate visible light and increasing the efficiency of the lamp. The protective layer results in a marked decrease in the hitherto accepted reduction in the lamp luminance in relation to lamp burning time.

Abstract: PROBLEM TO BE SOLVED: To unify temperature distribution in a refrigerating chamber by a method wherein the supplying amount of cold air to the fore surface side of a refrigerator and that to the rear surface side of the same are controlled independently. SOLUTION: A part of cold air in a cold air supplying duct for back surface (cold air duct for back surface) flows into an arrow sign direction through a cold air communicating duct 38 for side surface and is sent out of a side surface cold air outlet port near a door pocket 27, then, enters into a cold air supplying duct 30 for door, which is attached to the inner plate of a refrigerator door. The cold air is sent out of a cold air outlet port 31, on the side surface of a refrigerator door rack unit 32 provided in the cold air supplying duct 30 for door into receiving spaces for the door pocket 27 or respective door rack units 32 to cool foods in the receiving spaces of the door pocket 27 from the side surfaces of the same.  On the other hand, a cold air supplying duct for side surface is extended to the vicinity of the refrigerator door whereby the cold air can be supplied from a cooler chamber into a cold air supplying duct for side surface and the cold air supplying duct 30 for door whereby the new provision of a cold air communicating duct for side surface is not necessitated and the number of parts can be reduced.

Abstract: An adaptive filter suitable for speech analysis which is constructable on a silicon chip. The filter has a single multiplier and a single adder in series together with appropriate registers or memories so that the output of the adder is either looped back to the adder itself or alternatively is looped, after a delay, to the multiplier so as to perform the operations of an all-zero digital lattice filter in computing a moving average, employing linear predictive coding. Another register provides the multiplier with the constant values typically associated with lattice filter coefficients. Preferably the multiplier is an M-stage pipeline multiplier so as to reduce the area necessary for its incorporation on a silicon chip. The filter accepts digital samples of the voice input and outputs a compressed data representation of the input.
