Patent DE-2512197-A1 (DE)
Title: Differential steering control for battery driven vehicle - has impulse powered DC motors of variable pulse length for cornering
Inventor: DIETRICH BERNHARD
IPC: B60L15/20
Filed: 1975-03-20
Abstract: The battery driven, non-rail vehicle has two drive wheels powered by impulse driven D.C. motors. In order to prevent the inside wheel dragging on cornering, with the power fully removed from that wheel, the control circuit is improved by a steering linked impulse modulation circuit. This reduces the lengths of the impulses on the inside wheel in relation to the steering lock. A smooth traction drive is then ensured during cornering. When the steering lock exceeds a set amount the drive on the inside wheel is reversed for added effect.

Title: Tension control unit esp. for tape recorders - with compensation of vibrations caused by interaction of motor, tape and sensor
Inventor: PIOTROWSKI KARL-HEINZ ING GRAD
IPC: G11B15/43
Filed: 1975-07-23
Abstract: A magnetic tape tensioning unit for a tape recorder has a sensor (2, 9) to detect the tension between feed and take-up spools using a pressure cell or a resilient element. The braking or pulling effect of the spools is then increased or decreased depending on the tension, whereby forces due to tension are converted into an electrical signal to control a drive motor or a brake. The signals result from an exchange of vibrational energy between tape, motor and sensor, and are fed to the motor via a control unit so that the motor torque counteracts the vibrations of the sensor. The signals detected are enhanced by an operational amplifier.

Title: Cross country ski with plastics running surface - has fluted central area with inclined pattern hindering reverse motion
Inventor: SCHNURRENBERGER HERMANN
IPC: A63C7/06
Filed: 1976-03-12
Abstract: The cross country ski is provided with a polyethylene running surface which is polished in the normal way with a fine grain polisher. In the centre of the ski is an area of relatively coarse fluting across the ski. This fluting forms an aid for the skier while climbing inclines, by helping to stop the ski slipping backwards. The fluting can be made courser from each end to the centre. The fluting can be straight across the ski or in fish bone formation. This provides a ski which has a good sliding quality yet has a good grip while climbing on wet or dry snow or hard and icy snow.

Title: Thermal movement roller support for steam generator - of pressurised water reactor yields under excessive forces caused by rollers jamming
Inventor: HARAND ELMAR
IPC: F22B37/24
Filed: 1976-05-18
Abstract: The parent patent describes a movable support for a steam generator, intended to accommodate thermal movements, esp. for use with a pressurised water reactor, where a straight, horizontal pipe connects the reactor pressure vessel to the steam generator vessel. The steam generator is mounted, pref. by means of rollers, on a baseplate at an inclination determined by the ratio of the different in level between the reactor and pressure vessel supports and the length of the pipe. In this addition, the support is capable of yielding under forces exceeding those occurring in normal operation and resulting from the weight supported and the inclination of the roller plane. If a defect should occur in the support system, e.g. if the rollers should break, then the inclined plane is capable of yielding so that excessively high resistance forces are not applied, resulting in overstressing of the plant components.
