Patent DE-3122326-A1 (DE)
Title: Optical connector
Inventor: WOLPERT GERHARD ING GRAD
IPC: G02B6/38
Filed: 1981-06-05
Abstract: For the purpose of axial flush alignment of two ferrules (3, 9) which in each case contain the centrally fixed end of an optical fibre, use is made in the optical connector of a guide socket (jack) (7) consisting of plastic. At least three strips (14) projecting at equal angular spacings relative to one another are arranged in the guide socket (7). The strips (14) have guide surfaces (15) of concave shape, which extend over the entire socket length and form a circular cutout, interrupted by slots (16), for the ferrules (3, 9), which are round in cross-section and somewhat larger in diameter. The guide socket (7) is an injection-moulded part produced from polyamide reinforced with glass beads and provided at least at one end with run-in bevels (17) for the ferrules (3, 9). The radially symmetrically acting centring property is achieved either by the shaping of the socket member or by an appropriately elastic design of the strips (14), which have a cross-section which is hollow in the interior and is either essentially annular or in the shape of a circular segment. <IMAGE>

Title: Method for reducing the induced drag of a lift-generating wing and a device for carrying it out
Inventor: BRIX WOLFGANG DIPL ING
IPC: B64C23/06
Filed: 1981-07-10
Abstract: In the case of a method for reducing the induced drag of a lift-generating wing (aerofoil) which causes free angles on the wing, the vortex flow is disturbed in a deliberate manner in that additional bodies are arranged on the wing in the region where the vortices are created. At the same time, artificial vortices are produced at discrete points on the wing with the aid of the additional bodies, the rotation direction of which vortices is in each case in the opposite direction to that of the free vortex located at the same position along the span. Their vortex intensities are in this case controlled such that they are at least approximately the same as that of the free vortex at the same point along the span. A device is used for carrying out the method, in the case of which device vortex generators in the form of flow apparatuses having an air throughput are arranged on the wing, which flow apparatuses in each case have a spin-generating, adjustable air-guidance system in their interior. <IMAGE>

Patent DE-3140327-A1 (DE)
Title: Motor vehicle with pneumatic central locking system
Inventor: ANDRES RUDOLF
IPC: E05B65/38
Filed: 1981-10-10
Abstract: The invention relates to a motor vehicle with a pneumatic central locking system for the doors and at least the boot lid. Arranged in the feed line to the pneumatic working element of the closing mechanism of the boot lid is a delay device which is effective only for locking, so that, within a particular period of time after the driver's door has been locked, the boot lid can still be opened without key actuation. In central locking systems having single-chamber working elements and only one working line system which receives its different types of pressure from a dual-pressure pump driven as required and selectively generating a vacuum or overpressure, the delay device is formed from two parallel channel portions each containing a non-return valve which block relative to one another in opposite directions. One of the channel portions, specifically that which is open under a pressure load having a locking effect, contains, as seen from the working element to the dual-pressure pump, first a throttle, then a pressure accumulator and then the non-return valve opening in the direction of flow of the type of pressure having a locking effect. Arranged in the other channel portion is a special type of non-return valve which opens on one side in the direction of flow of the type of pressure having an unlocking effect, but which blocks both directions of flow for the other type of pressure. The switching elements of the delay device are appropriately integrated to form a compact constructional unit.

Patent DE-3215964-A1 (DE)
Title: Direction finding arrangement
Inventor: MOENICH GERHARD DR ING
IPC: G01S3/32
Filed: 1982-04-29
Abstract: An antenna arrangement having at least two directional patterns which have a null in a predetermined direction and have a different characteristic in the remaining area, supplies two bearing voltages corresponding to the reception via these directional patterns, from which the associated bearing angle is determined by a level comparison. The bearing error is improved within a wide angular range by aligning the null of the patterns with backscattering noise sources in the vicinity of the direction finding antenna. A conventional antenna arrangement of two intersecting double frames is advantageously used, sum and difference voltage being formed with each double frame and one of the two difference voltages being compared with the sum voltage which does not contain any components of the backscatterer.

Title: Head support for motor vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1982-12-15
Abstract: In a head support for motor vehicle seats, the head upholstery carrier is connected to the head upholstery carrier rods arranged in the seat backrest by means of an inclination adjustment arrangement. Each inclination adjustment arrangement has a circular cylindrical holding part which is attached to the head upholstery carrier rod and is engaged around by a plastic shell whose essentially parallel attachment legs are tensioned with respect to one another by an attachment element, such as a screw, rivet or the like, which penetrates them. With the present invention, the locking force which is applied by the attachment element and acts on the attachment legs is to be applied to the inclination adjustment arrangement in such a way that this locking force is transferred in an essentially uniform way to the attachment legs of the plastic shell even in the case of relatively large temperature fluctuations. In accordance with the invention, on or adjacent to the outside of each attachment leg a rigid plate-shaped component is provided assigned either to the attachment leg itself and/or to the head upholstery carrier wall bordering it on the outside. This rigid plate-shaped component extends with its lower region at least as far as the free end of the attachment leg and touches or intersects with its upper region a tangent which is aligned parallel to the longitudinal axis of the attachment element and laid on the inner circular contour of the open seam tube-shaped region of the holding shell.
