Patent DE-3205843-A1 (DE)
Title: Venting device for a compressed-air cylinder
Inventor: LECHNER ANTON DR DIPL-ING
IPC: F15B21/044
Filed: 1982-02-18
Abstract: In a venting device for a compressed-air cylinder, the piston (3) of the compressed-air cylinder is guided in an axially movable manner on the piston rod (5), the movement of the piston (3) being limited at one end by a stop ring (17) and at the opposite end by a locking ring (19). The restoring spring (7) of the compressed-air cylinder acts on the piston (3) in such a way that the piston is axially displaced on the piston rod either by the action of the restoring spring or, on the other side, by the admission of pressure in the primary space (31) and in the process comes to bear against the stop ring (17) in a sealing manner when a predetermined pressure is reached in the primary space. For sealing purposes, the piston (3) carries an O-ring (23) at the end face facing the stop ring. If this O-ring lifts from the stop ring upon appropriate axial displacement of the piston, a connection is immediately made between the primary space and the secondary space in such a way that, when the piston is displaced in such a way as to increase its volume, the secondary space is adequately vented in order to prevent a vacuum from arising. <IMAGE>
Patent DE-3214021-A1 (DE)
Title: Device for generating and representing three-dimensional images
Inventor: KELLER TONY WERNER
IPC: G02B30/25
Filed: 1982-04-16
Abstract: In order to generate and represent three-dimensional images, the images recorded at differential viewing angles are generated in a temporally alternating fashion and represented in a common image plane. The separation of the two images, which must be fed to the eyes of the viewer on two different channels, in order to give him the impression of space, is performed by electro-optic valves, arranged in these channels, and a switching device which acts to block or release the electro-optic valves of the channels in a synchronous manner relative to the alternating representation of the two images. The electro-optic valves can, in particular, be formed from LCD layers which can be brought alternately into transparent and opaque states by applying appropriate control signals. However, it is also conceivable to use polarisers whose direction of polarisation can be varied and which interact with fixed polarisers. A preferred application of this device is in connection with colour television systems which operate with line interlacing. In this case, the different images are then each assigned a field.

Patent DE-3228718-A1 (DE)
Title: Refillable pencil with automatic lead propulsion
Inventor: BUTKA KEMAL
IPC: B43K21/033
Filed: 1982-07-31
Abstract: A refillable pencil with automatic lead propulsion, especially suited for thin leads, contains a lead guide (2) which is coaxially displaceable in a housing (7, 10), projects partially therefrom downwards and completely encloses the projecting lead part (1) as far as the tip (2c). In the interior of the housing, an elastomeric ring (3, 13) in frictional contact with the inner wall of the housing encloses the lead (1) above the lead guide, with slight adhesive friction. It transmits the writing pressure from the writing tip (2c) to a pincer (8) which, even with slight compression of the elastomeric piece (3, 13), closes around the lead (1), retains it and so permits writing. Each time that the writing pressure is relieved (end of word), the lead guide together with the pincer drops downwards, the pincer immediately opening because the pressure on its underside is abruptly discontinued since the flanges (13a, 13b) of the elastomeric ring, because of the latter's friction against the inner wall of the housing, cannot be released as rapidly as the lead guide (2) falls downwards. <IMAGE>
