Inventor: DENZLER HEINRICH
IPC: G01K1/08
Filed: 1978-11-27
Abstract: A thermometer is supplied in the two-part sleeve. The latter additionally serves to make it even easier to read the thermometer. For this purpose one sleeve part (3) is provided with at least one lens (4) in such a way as to facilitate seeing through from outside onto the thermometer located in the sleeve, doing so in conjunction with a magnified thermometer scale. The sleeve part (3) accommodating the lens (4) can consist of a transparent plastic, the lens also consisting of this plastic material and being of one piece with the sleeve part.

Title: Projector film feed control - has stepping motor to step film through projector with continuous motor drive over sound track pick=up
Inventor: RIEGER THEO ING GRAD
IPC: G03B21/43
Filed: 1979-04-02
Abstract: The stepping motor is used for synchronised transport of film through a projector in such a way as to minimise associated noise. The transport system uses a continuous drive motor (1) to feed the film from the reel and over the sound track pick up (3) at a constant rate. Indexing of the film at a rate of up to 24 frames per second through the camera lens system (5) is achieved by intermittent motion of a friction wheel drive (8). The film indexing is provided by a stepping motor (4) driven by a pulse generator circuit. A sensor (7) monitors continuous film transport speed to ensure that the stepping actionis synchronised to the continuous drive motor.

Inventor: BERNEY JEAN-CLAUDE
IPC: G04C17/00
Filed: 1979-06-22
Abstract: An electronic watch comprising a device for controlling and driving the day of the month disc, wherein the wheel train supplies the energy necessary for moving the day of the month disc, but does not determine the instant of the jump, which may be initiated at any moment by an electrical signal, independently of the position of the wheel train. The device comprises a mechanism driven by the wheel train and arranged so as to disengage when the moving bodies of the wheel train, controlling the display, turn continuously in clockwise direction and to re-engage when said moving bodies turn in anti-clockwise direction. A control circuit determines, in a portion of the driving cycle in an anti-clockwise direction of rotation with a rapid rate, the jump of the display disc of the day of the month mechanism.

Title: Separate volume control for loudspeakers in vehicle - has parallel load resistor and double wiper potentiometer across each speaker unit for constant impedance non-interacting adjustment
Inventor: WELLHAUSEN HEINZ DIPL ING
IPC: H04R3/12
Filed: 1979-09-13
Abstract: Each loudspeaker unit can be independently adjusted for volume without interracting with other units and whilst maintaining a constant impedance. Each loudspeaker unit (2) presents the loudspeaker (8) impedance to the amplifier at its output terminals (4,9). The unit (2) contains a double wiper potentiometer (5,6) for volume adjustment and has a load resistor (11) in parallel with the speaker unit (8). The load resistor (11) and the speaker (8) are connected to opposite ends of the double wiper volume control (6), the load resistor being part of the double wiper volume control potentiometer (6). The volume of each loudspeaker unit can therefore be adjusted whilst the unit still dissipates the same power by altering the distribution between speaker (8) and load resistor (11) plus potentiometer (6). The equipment is intended for individual adjustment of speakers in motor vehicles.

Title: Multi-step thermoplastic vinyl aromatic cpd. copolymerisation - initiated by dissociating radical and heat in first step and by heat in second step
Inventor: WINGLER FRANK DIPL CHEM DR
IPC: C08F12/00
Filed: 1980-07-16
Abstract: Thermoplastically workable copolymers are produced by a multi-step process. In 1st step, a mixt. contg. vinyl aromatics and further monomers is copolymerised continuously in a flooded, ideally mixed-through tank reactor. In 2nd step, continuous copolymerisation is continued in a 60-85 vol% filled reactor. Novelty consists in initiating polymerisation in 1st step with an initiator dissociating into radicals and having half-life 1/20 of the average dwelling time at the prevailing polymerisation temp. The heat of polymerisation is abstracted through the cold-charged monomers and through the reactor wall. In 1st step, 50-100 mol.% of the monomer conversion is initiated by the initiator and 0-50 mol% by heat. In 2nd step, monomer conversion is initiated by heat and heat-abstraction is achieved by vapour-cooling. The copolymers can be injection-moulded, deep drawn or pressed to articles such as dishes, armatures, household articles, internal car fittings, boat-building, optics and electronics, and also worked to foils and containers for packing food and pharmaceuticals.
