Patent DE-3119177-A1 (DE)
Title: Seat belt
Inventor: ERNST HANS-HELLMUT ING GRAD
IPC: B60R22/12
Filed: 1981-05-14
Abstract: The invention relates to the special design of a seat belt for reducing injuries caused by accidents in the abdominal and pelvic region of the occupants. Under unfavourable belt-wearing conditions (belt geometry, belt slack), the lap belt can slip upwards into the abdominal cavity in an accident and cause internal injuries. A remedy for this problem is provided according to the invention by virtue of the fact that the belt-webbing section (2) located, when the belt is not being worn, between the lower securing point (6) and the deflection fitting (5) is wider than the rest of the belt webbing (3) leading from the deflection fitting (5) to the retractor (11). By virtue of the wider belt webbing, on the one hand there is a greater probability of the belt webbing following a favourable line over the iliac bones which can withstand loads well and, on the other hand, in the unfavourable case of the belt webbing slipping upwards there is a lower specific loading for the abdominal cavity. <IMAGE>

Title: Arrangement for supplying antenna voltages, which are unbalanced and balanced with respect to earth, of different frequency ranges to an unbalanced output
Inventor: WENDEL WOLFGANG DIPL ING
IPC: H03H7/46
Filed: 1981-10-14
Abstract: The invention relates to an arrangement for supplying voltages of various frequency ranges, which are unbalanced and balanced with respect to earth, to an unbalanced output, preferably for broadcast reception at low, medium, high and very high frequencies with a resonant transformer which exhibits at the base of the antenna, which is unbalanced with respect to earth, a winding having at least one tap for the unbalanced output, preferably for connecting the inner conductor of a coaxial cable. In this arrangement, the invention consists in that a further winding tap is connected to one half of an open dipole, the other half of which is connected to an additional winding which is connected to earth at the other end and which is wound in parallel with a part winding of the resonant transformer. The part winding with the parallel additional winding is a familiar balancing element which transfers the balanced dipole voltage without attenuation to the unbalanced output. The transformation ratio of the unbalanced voltages remains unchanged in the low, medium and high frequency ranges. It is advantageous if all windings are tightly coupled to one another on a ring core having high permeability and the least possible losses. The arrangement according to the invention can also be used in a simple manner in a dipole which is mounted set up insulated on the unbalanced antenna. Its lower part consists of a tube through which the balanced feed line with a characteristic impedance of 75 ohms is conducted from the arrangement according to the invention at the lower end of the tube to the open dipole.

Title: Displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C1/02
Filed: 1981-10-20
Abstract: The invention relates to a displacement machine for compressible media with at least one displacement chamber (4, 5) formed in the manner of a spirally running slot and arranged in a fixed housing (2, 3) and with a likewise spirally formed strip or tongue-like displacement element (8, 9) assigned to each displacement chamber, which element is mounted on a disc-shaped rotor (6) which can be driven eccentrically in relation to the housing in such a way that in operation each of its points performs a circular movement limited by the peripheral walls of the displacement chamber, and the curvature of which is so designed in relation to that of the displacement chamber that it almost touches the inner and outer peripheral walls of the displacement chamber on at least one sealing line continuously progressing during operation, and with devices (31, 32) for sealing off the axial and radial gaps formed between the fixed housing and the rotor. In order to obtain an effective seal between the individual working chambers formed in the housing, it is proposed to provide a selectively applied roughness to one of each of the faces of the components to be mutually sealed off, the tips of which are plastically deformable or abradable when the machine is run in. It is also advantageous if a band-shaped sheet metal strip is provided as backing for the roughness. <IMAGE>
Patent DE-3142181-A1 (DE)
Title: Sequential changeover contact system
Inventor: SEEGER GUNTER A ING GRAD
IPC: H01H50/54
Filed: 1981-10-21
Abstract: The invention relates to a sequential changeover contact system having two contact pairs one of which is closed in the quiescent state and the other of which is open in the quiescent state. When this sequential changeover contact system is operated it is intended that the opening contact should not be lifted until the closing contact has already come to rest on its mating contact. The invention is based on the object of constructing such a contact system so that the operating movement of the armature of the magnet unit of so-called small relays is adequate to effect the necessary large contact movement which finally ensures the desired large contact separation in the quiescent position. This object is achieved according to the invention in that the two contact pairs are arranged in a row which inherently extends at right angles to the longitudinal axis of the magnet unit. In consequence, it is possible to use not only the relatively short contact springs as in the past, and hence a relatively large contact movement, but the contact separation in the quiescent position is larger than in the past. <IMAGE>

Title: Method and device for manufacturing a car wheel of a specific type
Inventor: WIPPERFUERTH DIETER
IPC: B23B39/20
Filed: 1982-09-11
Abstract: The method for manufacturing a car wheel of a specific type in accordance with the German Patent Application P 3216566.8 is simplified in that, in order to adapt the central bore (9) of the wheel body, an inset ring (11) is clipped into precisely this central bore (9); therefore the drilling of the central bore (9) can be dispensed with. For this purpose, the inset ring (11) has in particular a dividing gap (16), by means of which it is given a specific resilient effect. Since the central bore no longer has to be drilled, the wheel body can be clamped into the central bore (9) by means of an expanding mandrel for the purpose of finishing. Only the hole circle for the wheel bolts has to be produced then during finishing. <IMAGE>

Title: Two-material combination slide bearing (combination bearing)
Inventor: WEBER WOLFGANG DIPL ING
IPC: F16C33/04
Filed: 1983-06-21
Abstract: The manufacture of thick-walled slide bearings from a combination of two materials, for example as self-lubricating solid-lubricant bearings, was hitherto only carried out to a limited extent since the introduction of the corresponding pockets and grooves was only possible mechanically, involving considerable outlay. According to the present invention, these grooves can be formed during casting, extrusion moulding and extrusion by appropriate shaping of the moulds and cores (mandrels). The blanks thus obtained, which predominantly should be tubes, can then be centrifugally cast with the second material, for example lubricant or white metal, the pockets and grooves filling with the second material. The further mechanical processing is then carried out by lathe-turning in a known manner.
