Title: Bag filter for gas streams - with bottom entry and lower bag row more widely spaced than upper
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/02
Filed: 1973-12-11
Abstract: Bag filter for gas streams consists of a series of filter bags mounted above a collection hopper in which is an elongated entry port for air.

Title: Machine for making longitudinally grooved pins - separates pins from continuous wire by circumferential notching before axially pressing
Inventor: SICHELSCHMIDT KARL
IPC: B21H7/18
Filed: 1974-02-22
Abstract: The machine produces pins with longitudinal pressed grooves from a continuous coil of wire. The required length of wire is separated from the free end of the wire by radial notching. The separated pin is subsequently notched longitudinally over its whole length by pressing. The clamping arrangement for the end of the wire acts simultaneously as the notching device. This arrangement has a clamping sleeve with conical head whose longitudinal slots accommodate notching tools which may have different slopes and interrupted notching edges. Better tolerances can be achieved in this machine owing to separate pressing of each pin.

Title: Single crystals of bismuth rare-earth garnets - lead-free bismuth gadolinium iron garnets with high faraday effect
Inventor: ITO SHINICHI
IPC: C30B9/06
Filed: 1974-04-18
Abstract: A mixt. of oxides is used in the desired proportions, except that more bismuth oxide or boric oxide is used than the theoretical amt. required to form the single crystal; the mixt. is melted and cooled at a rate of 0.1-10 degrees C./hour to 950 degrees C., then cooled to room temp. Alternatively, the melt temp. can be reduced below the saturation temp. and a garnet inoculant used. Bismuth doped, rare-earth-iron garnet single crystals can be crystallised from their own melts within area (ABCD) of a pseudo-ternary diagram where B2O3 can be used in place of Bi2O3 up to concn. of 0.5 mol. per mol. of Bi2O3.

Title: Modulus of elasticity determination - from stress-strain increment ratios on tensile tester and computer
Inventor: VOLL HUBERT PAUL
IPC: G01N3/02
Filed: 1974-05-21
Abstract: The modulus of elasticity of metals is determined by determining with the aid of a tensile test rig and a computer the ratios of the increments of the stress to strain, its maximum value, and those ratios which differ by no more than 1% from the max. The gradient of the elastic line is plotted from them as a function of the stress. This is a rapid and accurate way of determining automatically the modulus of elasticity independent of the kind of metal, of the temp. and of the speed with which the tensile test is carried out.

Title: Arrgmt. for controlling output of hot gas piston engines - by varying the mean pressure of gases in the engine
Inventor: HUEBSCHMANN KARL-WOLFGANG DIPL
IPC: F02G1/05
Filed: 1974-08-27
Abstract: The arrangement consists of an accumulator and a compressor for the gas used in the engine. The outlet of the compressor and the accumulator can be connected to the engine to increase the pressure of the working gases. The compressor inlet and the accumulator can be connected to the machine to reduce the pressures. Two three-way valves allow the gases to flow as follows: To increase the pressure, two flows from the outlet of the accumulator to the engine, one directly and one through the compressor. To maintain the pressure steady, one flow from the compressor outlet to the accumulator and from the accumulator back to the compressor. To reduce the pressure, two flows from the working chambers of the engine, one from one chamber direct to the accumulator and the other via the compressor to the accumulator, both paths being open at the same time.

Title: Equaliser for signals with quantised amplitudes - is for distortions on the average smaller than half the quantisation step
Inventor: HORVATH STEPHAN
IPC: H04L25/03
Filed: 1975-01-24
Abstract: The equaliser comprises an adjustable scanning filter for signal distortion compensation, which converts the input signals by addition, subtraction and multiplication operations and delivers the compensated signals to its output. A decision circuit is connected to the filter output, allocating each input signal to the next quantisation step and delivering a corresponding quantised signal. Its output is connected to the equaliser output. A difference forming element, is connected to the filter and decision circuit outputs, which forms an error signal depending on the differences between the filter output signal and the corresponding quantised signal delivered by the decision circuit. A device receiving this error signal and adjusts the filter accordingly. The scanning filter splits the computing operations in a number of elementary operations, each corresponding to a basic operation, with their relations arranged in two groups.

Title: Control circuit for DC motors in film cameras - avoids overshoot and sluggish response by using load-dependent feedback and brake
Inventor: FLANDORFER ROBERT
IPC: H02P7/288
Filed: 1975-04-26
Abstract: The control circuit is for dc motors that set a film camera's aperture and avoids the problems of overshoot and sluggish response in existing circuits by employing load-dependent feedback and providing a braking device for the motor. The brake may be mechanical (or given braking moment), or electrical. If electrical, it may be formed by the low dynamic internal resistance of the bridge that drives the dc motor, or by a shunt circuit in parallel with the motor, or by the feedback circuit itself. The input variable to the control circuit consists of the output of a photosensitive resistor.
