Title: Pivot support for e.g. TV camera - has holder pivoted to frame in turn pivoted to fixed main part and with position locking screw
Inventor: NAKAMURA TOYOSAKU
IPC: F16M11/10
Filed: 1978-11-13
Abstract: The support has a main part (A) with a pivoted frame (B) mounted on it. A holder (C) is pivoted to the pivoted frame.

Patent DE-2944517-A1 (DE)
Title: Incandescent-plug control for diesel engine - has bimetal switch with heater controlling current supplied to plug
Inventor: BELL LON E
IPC: F02N19/04
Filed: 1979-11-03
Abstract: The control regulates the temp. of incandescent plugs by cyclically passing current from a battery to the plugs. A first bimetal element is heated by a first resistance heater and operates a first switch as it moves. The switch disconnects the first heater's current and breaks the circuit between battery and incandescent plug. The heater and the plug are switched on and off simultaneously and in the same direction. The heater and the pluq heat-up and cool-down together at rates that are roughly proportional. The bimetal element is in thermal contact with the engine so that it is subjected to the same thermal conditions as the pluq.

Patent DE-2950978-A1 (DE)
Inventor: PROFOS DIPL-EL-ING ETH
IPC: H02M5/297
Filed: 1979-12-18
Abstract: The externally-controlled flyback converter converts a low frequency supply voltage into a higher carrier-frequency voltage which can be modulated, to be precise such that the latter can be supplied to the low-frequency voltage network again. The flyback converter is used, for example, as a transmitter for information items using the power supply network as a transmission channel and consists of a required-value transmitter (14, 15, 16), two current transformers/voltage converters (10, 11) with an adder (13), a switched-mode regulator (12), a polarity reversing element (18) with a changeover switch (17), two controllable semiconductor switches (2, 3) each having a control amplifier (23, 24) operating in the push-pull mode, two commutation aids (21, 22), a coil (1) having a centre tap (4), a polarity detector (19) and two low-pass filters (8, 20). The switched-mode regulator (12) keeps the sum of the two transistor currents (I1, I2) approximately constant, so that the low-frequency voltage (U1) emits energy to the first coil element (5) during the first switching phase for a longer period than it receives energy back from the second coil element (6) during the second switching phase, and thus compensates for the energy losses in the flyback converter. <IMAGE>

Inventor: RETTIG RUDOLF
IPC: C05F17/02
Filed: 1980-04-19
Abstract: A compost bin with bottom extn. of mature compost holds the domestic refuse and garden rubbish in a cylindrical shell, open at both ends. It is supported on four legs, high enough to push a wheelbarrow under it. The open bottom is surrounded by a double ring, leading an axial gap, wide enough to push through a number of freely movable horizontal tubes. The first layer can be stopped from falling through the grate formed by the tubes by a layer of newspapers. This is a simple way of extracting mature compost from the bottom. The lateral shifting of two tubes to discharge compost requires little manual effort.

Title: Carburettor with accelerating pump - has additional air inlet with automatic valve to maintain fuel air ratio during acceleration
Inventor: ACOSTA ASTUDILLO
IPC: F02M3/10
Filed: 1980-06-27
Abstract: The carburetter body (4) has a bore (3) into which the slow running adjusting screw (1) is threaded. The slow running jet (6) opens into the bore which in turn opens (7) into the carburetter inlet (2). The needle end (8) of the adjusting screw has a bore (12) which communicates (9,18) with outside air. The bore is closed by a spring loaded non return ball valve (10) within the screw. When the accelerator is depressed suddenly and the accelerating pump is activated, the increased air flow through the main passage produces a pressure drop which opens the non return valve (10) and increases the air flow to balance the fuel from the accelerating pump.

Title: Logic state analyser with select comparator and trigger store - detects input bit combination and stores in fast intermediate register
Inventor: BERKA JEAN-CLAUDE DIPL ING
IPC: G06F11/25
Filed: 1980-12-24
Abstract: The logic state analyzer has a very wide and programmable trigger selection for complicated sequential logic networks and microprocessors and stores selected words for further tests. It achieves this in a cycle comprising three phases: in the first the input bit-combination is detected and stored in a fast intermediate register, in the second phase the 'enter'- decision is made and the third is the 'write' phase. A line adaptor and data input unit are linked via a selector to the intermediate register which, in turn, is connected to a store area and trigger stores which pass information to the select- comparator.

Title: Electronic counter in BCD 8421 code
Inventor: MERKLE PAUL
IPC: H03K23/56
Filed: 1981-01-03
Abstract: The electronic counter according to the subject matter of the invention is an electronic counting circuit which, in the switched-on state, counts current pulses (voltage pulses). Due to the circumstance that the counting result is indicated as a decimal number, such a counting circuit consists of subsections (decades) which indicate the corresponding digit (decimal digit) for their decimal place. This counter is a binary-decimal counter because its decades count in accordance with the binary weighting system from 1 to 10. To display the result number consisting of decimal digits, a decoding circuit is also additionally required for each decade, which circuits indicate the binary-coded decade storage values as decimal digits. Figure 1 shows one decade of the up counter and Figure 2 shows one decade of the down counter. Each decade consists of four dual flip flops, which are not shown doubled in Figures 1 and 2. The flip flops are activated synchronously. <IMAGE>
