Patent DE-3226902-A1 (DE)
Title: Window or door having an antechamber seal
Inventor: HABICHT SIEGFRIED
IPC: E06B7/23
Filed: 1982-07-17
Abstract: The window or the door is equipped with an antechamber seal, by which the chamber between the blind frame and the casement or leaf frame is divided into two spaces. The antechamber seal, which is fixed in a C-shaped or U-shaped anchoring groove of the blind frame, is made up of angular seal corner pieces and of seal profiles, which are fitted between the seal corner pieces. The butt connection between the legs of the seal corner pieces and the seal profiles is made without using an adhesive. The legs of the seal corner pieces have butt straps which are offset laterally with respect to the end faces of the legs and protrude beyond the end faces, so that these butt straps overlap the ends of the seal profiles fitted between the seal corner pieces. This overlapping may be arranged in such a way that a frictional connection is produced between the butt straps of the seal corner pieces and the ends of the seal profiles arranged between the seal corner pieces.

Title: Device for actuating the flushing of a WC installation
Inventor: GLAUSER KURT
IPC: E03D13/00
Filed: 1982-07-27
Abstract: Two electrodes (10, 11) are arranged on the trap (3) of a WC installation (1, 2, 3, 4). The electrodes are connected to a control apparatus (9) which actuates a solenoid valve (7) to trigger respective ends of the flushing operation. The electrodes (10, 11) form a variable capacitor of an oscillatory circuit in the control apparatus (9). When the water in the trap (3) is contaminated, the dielectric of the capacitor (10, 11) changes, resulting in a shift of the frequency of the square wave generator in the control apparatus (9). At a given, adjustable threshold, the flushing operation is triggered and after a likewise preselectable delay time the flushing operation is ended again. The device has the advantage that the trap cannot be contaminated due to corrosion of the electrodes, and can thus be used in all common trap types. <IMAGE>

Title: Suspension device, especially for optical-fibre cables, and an insulating body therefor
Inventor: LEITSCH FRANZ
IPC: H02G7/05
Filed: 1982-11-12
Abstract: A suspension device (39) which is used for guiding especially optical-fibre cables (42), has a guide part (40), for example in the form of a steel spiral, through which the optical fibre cable (42) is passed. The guide part (40) is attached to heavy-current pylons by means of an attachment part (41).

Title: Typewriter or similar office machine having an ink jet printing mechanism
Inventor: MARTENS HORST
IPC: B41J2/19
Filed: 1983-10-28
Abstract: In typewriters or similar office machines having an ink jet printing mechanism, it is necessary to change an empty ink reservoir for a full one (23). During this exchange operation and while there is no ink reservoir (23) present in the receiving device (37) of the machine, the pulse generators ejecting the droplets of ink from the spray head must be prevented from being charged. Only in this way can suction of air into the pump chamber and other interferences be avoided. According to the invention, the printing operation of the machine is guaranteed by a lever linkage (41), by means of which the carriage (9) with the spray head (33) can be engaged in the positon of rest arranged outside the printing area and the mains switch (67) can be actuated. This lever linkage (41) with an on/off switch button (43) can be blocked by a blocking member (85) on the receiving device (37) for the ink reservoir (23) in such a way that the mains switch (67) can only be switched on when the ink reservoir (23) has been inserted correctly. Additionally, the ink reservoir (23) can only be removed when the machine is switched off. As a result, interferences in the printing operation are reliably avoided. <IMAGE>

Title: Ground-working appliance having a large working width for mounting on a tractor
Inventor: BOHNENKAMP WILFRIED DIPL ING
IPC: A01B49/02
Filed: 1983-11-10
Abstract: The appliance frame (1), on which the ground-working implements are located, is coupled by means of a transverse axle (14) to the lower links of the three-point linkage of a cutter. The transverse axle (14) is horizontally movable to a limited extent in relation to the appliance frame in apertures (13). Under low tensile forces, such as occur during transport, the transverse axle (14) is drawn by means of springs (21) towards the rear edges (13b) of the slots (13). Under high tensile forces, such as occur during ground-working, the springs (21) are further tensioned and the transverse axle comes to bear against the slot edges (13a). This type of movability of the transverse axle ensures some articulation between the transverse axle (14) and the appliance frame (1), so that the appliance is suitable particularly also for coupling to an articulated tractor. <IMAGE>

Title: Method of producing a glass pipe suitable for ampoule and flask production
Inventor: RITT HANS GEORG DR
IPC: C03B23/09
Filed: 1983-11-15
Abstract: In a method of producing a glass pipe which is suitable for the production of ampoules and tubular flasks, a length of pipe is initially separated from a continuous line of glass and then one of the two open ends is softened and drawn out, by means of a force acting in the axial direction, until the pipe collapses and a first base is formed. Then a small aperture is made in the pipe wall or in the pipe base and the second, open end is closed by a second base which is produced by the same method as the first base. Finally, this small aperture is sealed by a film. These pipe lengths produced in this manner are in a far cleaner state than the tubes produced by conventional methods for the production of ampoules and flasks.

Title: Release pin device for a parachute harness release mechanism
Inventor: NAAB CARL W
IPC: B64D17/32
Filed: 1984-05-05
Abstract: An improved parachute harness release mechanism, which can be operated by water, has a removable sleeve which is arranged between the spaced-apart sections of a yoke. A suspension strap is wound around the sleeve. The sleeve has a hole, and a piston and a cylindrical pin in the normal condition bridge over the gap between the ends of the sleeve and the corresponding, aligned openings in the first section and second section of the yoke, which are at a distance from one another. An explosive charge which is mounted on the piston end is detonated by a water-operated measurement device and drives the piston completely into the sleeve. This then pushes the cylindrical pin out of its bridging-over position. A novel release pin arrangement is also used, which contains not only the cylindrical pin but also a first supporting element which is arranged in the second aligned opening of the yoke. This supporting element has a cavity. Said cavity can hold the cylindrical pin. Furthermore, devices are proposed which hold back the cylindrical pin in the normal condition. Said devices hold the cylindrical pin in a bridging-over position in the normal condition, one part of the cylindrical pin being arranged in the hole in the sleeve and another part of the pin being arranged in the cavity in the supporting element.
