Title: Stepper motor for driving printing head - has magnetic means for axially displacing rotor in desired direction
Inventor: HUMBS ROLF DIPL ING
IPC: H02K37/04
Filed: 1974-09-27
Abstract: The motor typically forms part of the drive for a typing mechanism, for example in a teleprinter. The rotor (52) differs in core length from the stator (3) and is carried in bearings which allow axial movement (h). Coils are provided on the stator to produce the necessary step rotation and also the axial thrust, when required, to place the desired letter in position for printing. Means may be provided, for example a spring, to return the rotor to a defined position. By arranging the printing mechanism in this manner the weight of the parts which have to be moved along the line of print is reduced.

Title: Slip frequency optimising regulator for vehicle async. AC linear motor - uses slip frequency and force changes to optimise slip for greatest force
Inventor: ANSGAR JOHN DIPL ING
IPC: H02P23/08
Filed: 1974-12-20
Abstract: The slip frequency optimising regulator for a vehicle asynchronous alternating current linear motor driven from inverter, makes use of the analog product of changes in the slip frequency and changes in the force to set the slip frequency to an optimum. A pulse signal determines the switch-over between the motor and generator operation in dependent on certain time conditions and without speed measuring. The advantage lies in reducing the amount of measuring circuit elements and in ensuring that the greatest possible force is achieved for any given current.

Title: Thermoelectric measurement of brake lining temperature - using a duct in the lining for transducer mounting
Inventor: FABER EKKEHARD VON DIPL ING
IPC: G01K13/04
Filed: 1975-01-30
Abstract: The method is for measuring the temperature near a moving surface, particularly in a drum of disc brake, in which the thermoelectric element is mounted in a duct, so that accurate results are achieved. The transducer was formly embedded in the lining. In the new system a duct (8) perpendicular to the lining (6) face and right through the lining, carries the thermoelectric transducer (9) at the interface of the lining and brake disc. A lead (14) carries the signal away through the back of the lining. Because of the presence of the transducer right at the interface, improved accuracy is obtained.

Title: Machine for continuous drying and/or joining of veneer - utilises heat energy by passing veneer strip between heat controlled elements above and below it
Inventor: MARTIN JEAN-MARIE MICHEL
IPC: F26B13/02
Filed: 1975-06-20
Abstract: Arrangement for the continuous drying of pared or cut veneer between heat conducting conveyor belts in the direction of the grain or vertical to it. The machine consists of two metal conveyor belts and running on rollers. The belts must be thin and of a construction that allows air and steam to pass through. Below the first belt is an insulating plate, and a heating plate, which receives heating or cooling medium through pipes or flexible tubes. Above the second conveyor belt, are one or more heated gliding shoes, which by their weight push on the belt, which for better control of process heat in the elements can be varied from hot in the centre to cooler at the end. The two conveyor belts between which the veneer is transported can run at the same or at variable speeds to each other. In another arrangement the veneer may run through a series of conveyor belts.

Title: Improvement method for control circuit response - relates to input variable variations and to disturbances and is esp. for rectifiers
Inventor: STEMMLER HERBERT DIPL ING DR
IPC: H02M7/155
Filed: 1975-07-10
Abstract: Harmonics of the control variable at the rectifier output are at first represented in the form of a corresponding voltage by measuring the total voltage at the rectifier output. Difference between this voltage and control voltage at the rectifier input is produced by a subtractor circuit. The control voltage corresponds to the fundamental of the rectifier output voltage, so that the difference voltage corresponds to the harmonics in the output voltage. A computer circuit, which simulates the relation between voltage and current, separates the harmonics in the rectifier output current, and this current is subtracted from the total current by a further subtractor circuit, so that the resultant current is nearly completely free from harmonics.

Title: Tipping control for trailerRR - with height adjustable rear tipping axis and single central ram under frame
Inventor: HOFFMANN HEINZ
IPC: B60P1/16
Filed: 1975-08-21
Abstract: The tipping surface of the trailer is mounted on a rigid support frame which has a vertical, telescopic ram under its centre, with the ram pivotted on the chassis. The load surface is set low on the chassis so that it can be loaded manually. The rear of the surface is hinged on detachable pivots at the ends of vertically adjustable posts. To tip the load onto a heap, the rear posts are released and the front edge of the surface secured on front pivots. The ram is operated to swing the surface upwards about the front axis, thus extending the rear posts. These are then locked in the raised position and the front pivots released so that the surface can be tipped over the raised rear axis. The trailer can also be tipped over either edge by suitable choice of fixed and released pivots.
