Title: Embossed plastics film varnished before embossing - gives appearance of leather with structured structured surface
Inventor: MESSNER JAKOB
IPC: B44F9/12
Filed: 1973-07-21
Abstract: The varnishing is effected with a non-thermoplastics lacquer or one which has a higher softening range than the matrix. The claimed treatment results in pleasing high-gloss surface, even in the case of vacuum-embossed articles where the distortion of the micropores in the film, caused by the shaping process, often gives an undesirable matte surface. The plastic has the appearance of leather.

Title: Electric motor with speed reducer - has armature mounted for rotation to permanent magnets armature shaft
Inventor: CIFUENTES LUIS
IPC: H02K7/08
Filed: 1973-12-03
Abstract: The electric motor has a metal casing in which two permanent field magnets are secured. The armature is mounted by journals in sintered bushes, for rotation relative to the magnets on a shaft having a screw threaded portion for meshing with a toothed wheel. A stop of plastics material engages the end face of the shaft of the armature when the motor is operating, the stop having a hexagonal cross section shank force fitted into the casing which serves to prevent rotation of the stop, and therefore acts to support the armature when it is rotating. The motor further includes a stop device in the form of a blade being operated to short circuit the armature when the operating switch of the motor is in the stop position.

Title: Power control for X-ray tube cathode heaters - ensures constant resistor output power regardless of supply voltage variations
Inventor: OCHMANN RUDOLF DIPL ING
IPC: G05F1/66
Filed: 1974-04-25
Abstract: The circuit controls the power output from a resistor through the width of the resistor supply pulses. A measuring device converts the parameters controlling resistor output into electrical signals which are multiplied and the resulting signal (Uq) fed to an integrating circuit. When the integrated signal (UI) reaches a set point (UR) in a comparator, a signal (Uk) is generated to disconnect the feed pulse (U1) from a pulse generator. The integrating circuit integrates the signal (Uq) issuing from the multiplier after the start of the pulse disconnection signal (Uk) and stores it to form a starting value for the integrated result signal (UI) on the appearance of the next feed pulse (U1).
