Patent DE-2314889-A1 (DE)
Title: Tyre cord preparation process - has cutting blade to sever wefts from a woven leaving warps
Inventor: LEON DIPL-ING GOERENS ROBERT
IPC: B29C70/20
Filed: 1973-03-26
Abstract: The system is designed to reduce a woven fabric of warps held in place by weak wefts, to the warps alone, the cutting blade severing the wefts which are then led off as loops, with a support unit for the warps to pass through a rubber coating station for use as tyre cord material. This allows the use of easily manufactured woven fabrics for conversion to warps, without introducing weak points where the wefts cross the warps.

Patent DE-2351046-A1 (DE)
Title: Permanent magnet arrangement giving mechanical energy - employing repulsion effects and shunting magnets
Inventor: SCHATZ BERTHOLD
IPC: H02K53/00
Filed: 1973-10-11
Abstract: The main magnet is fixed in space and can be approached, in an attraction sense, by two auxiliary magnets, which may be fixed to a non-magnetic rotating disc structure. When the main and auxiliary magnets are in line the work magnet, which may also be on a revolving non-magnetic disc, is brought close to the main one. The work magnet is polarised to repell the main magnet, but, with an auxiliary magnets in position its flux is shunted and no repulsion takes place. When the auxiliary magnets are removed, for example by rotating their mounting disc, mutual repulsion drives the work magnet and liberates mechanical energy. The disc on which the work magnet is mounted can thus be made to rotate. Several magnets may be used.

At the opposite ends on the cutters to the flat, cutting ends, are bent ends which are inserted into holes in the disc and point backwards in the direction of rotation. The sprung cutters can be screwed, riveted or otherwise attached, with check nut.

Patent DE-2358676-A1 (DE)
Title: Control monitor for marine generators - monitors excitation currents and reactive loadings of all parallel generators for fault cut-out
Inventor: FRERICHS HEINO
IPC: H02H7/06
Filed: 1973-11-24
Abstract: The monitor, for regulators of parallel-operating generators on board ships, drilling rigs etc., compares the excitation currents and the reactive load distribution of all the generators supplying the network at any moment. Any detected deviations in magnitude and direction of these monitored quantities causes the generator coupled to the faulty regulator to be switched off. A d.c. voltage proportional to the excitation current is obtained from each generator and used to form a mean value for all generators. This mean value is compared in an AND logic with a reference value. For the reactive loads a voltages proportional to generator currents and voltages are added vectorially and likewise passed to the AND logic.

Patent DE-2362642-A1 (DE)
Title: Electronically controlled DC machine - has star and delta-coupled armature windings to avoid anti-parallel thyristor control
Inventor: SCHADE WALTER DR
IPC: H02K29/00
Filed: 1973-12-17
Abstract: The electronically controlled D.C. machine has a drum armature whose winding construction contains both a star coupled winding and a delta coupled winding so that no anti-parallel control is necessary. The armature winding is, therefore, divided into two mutually insulated, but inductively coupled windings, thereby giving the advantages of both star and delta coupled windings. Using these two winding types together means that the anti-parallel control thyristors etc. are not needed since the star coupled windings neutral point acts as the D.C. pulse input or return line. The starting voltages may be taken up at the connecting points by the delta coupled windings.

Patent DE-2404015-A1 (DE)
Title: Transistor push-pull output stage for differential amplifier - has two complementary transistors free from static current
Inventor: FREULING MARTIN
IPC: H03F1/32
Filed: 1974-01-29
Abstract: The amplifier output is connected to the transistor bases. A resistor is provided between the transistor emitters and bases. It bypasses control paths of the transistors and makes possible a feedback to the amplifier inverting input. The circuit can be extended by a further stage to form a Darlington circuit. The two stages have transistors with the same current gain, and the second stage has a similar resistor between emitters and bases, making possible a feedback to the amplifier inverting input. The exponential function of the current voltage characteristic of the control line of the output stage transistors ensures that the acceptance of current by the latter gradually climbs without gap jumps.

Title: Chipboard from cakes of thermosetting resin impregnated chips - by mixing and controlling heating in enclosed space
Inventor: PFEIFFER HEINRICH
IPC: B27N3/18
Filed: 1974-03-01
Abstract: Chipboards, made from cakes composed of thermosetting resin-impregnated chips, are finished in a press so that chip mixing and cake preheating are carried out in an enclosed space and teh preheating to the thermosetting temp. following mixing is carried out such that the temp. is reached at that pt. in the press at which the pressure has its max. value. Thermosetting temp. is above 100 degrees C. Controlled preheating of the cake permits redn. of the max. pressing pressure and pressing time. In stage presses, this pt. is attained between the press platens at the time when the cake reaches its predetermined thickness. In continuously operating presses the pt. is reached at the nip of the press. Pref. the temp. of the chips and the resin are maintained at a constant value in the chips spreading station and the rate of throughput of the mixt. is controlled by measuring the temp. of the cake just before its inlet into the press nip.

Title: Measurement amplifier for analogue test results - has differential input stage followed by amplifying stage controlling evaluation device
Inventor: GRAETSCH WILFRIED
IPC: H03G3/02
Filed: 1974-06-08
Abstract: The input stage gain of the measurement amplifier can be set in several steps from off to maximum gain. The output is connected to the constant gain second stage through a voltage divider consisting of a potentiometer and several fixed resistors, followed by an impedance transformer. The input stage's own input is connected to frame through an adjustable voltage divider suppressing push push operation.

IPC: F16H47/08
Filed: 1974-08-20
Abstract: There is a hydrodynamic torque converter with the pump wheel connected to the input shaft of the gearing and the turbine wheel providing the output drive. Pressure operated brakes control the converter guide wheels by contra rotation or simple braking of the mechanical gearing.

This patent describes in detail the control for the three systems. Each has a master valve connected to a pressure source and a control mechanism with several positions. This controls the ratio of input to output shaft speed. In the first positional the systems are separate; in the second position for forward or reverse one of the brakes for the gears is applied and in the third position for forward or reverse engages the change gear. Below a specified figure for the ratio of input to output speed, contra rotation is used. Above this figure simple rotation is used.
