Patent FR-2503057-A1 (FR)
Inventor: QUEVEAU GERARD
IPC: B60J7/053
Filed: 1981-04-07
Abstract: The invention relates to the opening system for sliding roofs, said system containing a slide which is connected to the sliding plate during displacement and runs on a fixed guide rail and contains a rotary crank which drives a pressure-resistant toothed belt which itself drives a sliding device. The problem consists in permitting a double movement sequence, firstly vertically then horizontally, in which case as little friction as possible occurs. In accordance with the invention, a screw is provided which is connected to the sliding plate and to a nut which is connected vertically to the sliding device, and a rotation blocking device for this nut and a wing and a tappet as blocking device of this screw-nut structure with respect to the guide rail, the toothed belt finally containing a device for driving the nut in rotation and in a sliding movement. The invention is used in particular on the sliding roof of motor vehicles.

Title: Magnetic tape cassette for e.g. video recorder - has hub carrying tape braked to prevent slack in tape when cassette is removed from recorder
Inventor: TSUBAKI HISANORI
IPC: G11B23/087
Filed: 1981-06-04
Abstract: In a magnetic tape cassette the hub carrying the magnetic tape is braked to prevent the tape from slackening when the cassette is taken off a recorder. The hub is of double structure comprising an outer flangeless hub (12) carrying the magnetic tape and coupled to an inner hub (6) which is axially movable within the outer hub, the inner hub having a shaft portion (7) and a peripheral portion (10), the underside of which has radial gear teeth. In the dismounted condition of the cassette, the gear-toothed portion (10) is thrust into engagement with a gear-toothed part (5) of the cassette casing by spring (15), thereby applying a braking force to the outer hub (12) through the inner hub (6). When the cassette is positioned on a recorder, the inner hub (6) is moved within the outer hub by the drive shaft (8), against the bias of the spring (15), to disengage the two gear-toothed parts.
