Filed: 1986-01-24
Abstract: A pneumatic vehicle tire for trucks, especially for the drive axles thereof. In the region of the edges of the tread, the tire has circumferential rows of blocks separated by grooves that open freely to the sides. Provided to both sides of the laterally outwardly disposed rows of blocks is a practically cylindrical surface. In order to increase the capacity of the shoulder regions of the tire to withstand dynamic stresses, and also in order to increase the support surface of the tire upon soft ground, the base of the aforementioned grooves merges in a stepless manner with the lateral cylindrical surfaces. Advantageously, the laterally outwardly disposed edges of those blocks that form the edges of the tread merge with steep side surfaces that are disposed perpendicular to the cylindrical surfaces.

Patent DE-3605943-A1 (DE)
Title: Apparatus and method for discharging heavy material
Inventor: TIMMERMANN HELMUT
IPC: B03B5/24
Filed: 1986-02-25
Abstract: A closure member (8), which projects from above in a wedge-shaped manner into the passage opening (3) in the jig bed (1) of a jig washer, permits, by means of its long control path or because of the long control time, a very good discharge control of the heavy material. The mechanical construction is considerably simplified. No material accumulated in a shaft for alternating the jig water vibrations is necessary above the closure member, especially when the heavy material falls into a chamber having a reduced jig water amplitude. The squinch formation, which hitherto has not always been avoidable even with a shaft, no longer occurs; the discharge of light material is certainly avoided with this discharge apparatus. Depending on the position of the discharge member in the jig bed, the heavy material is discharged on one side or both sides of the closure member. <IMAGE>

Title: Plastic component of the tailgate (boot lid) of a motor vehicle
Inventor: BAUER KARL DR ING
IPC: B62D35/00
Filed: 1986-03-20
Abstract: The invention relates to a plastic component of the tailgate, in particular of a motor car, which is produced by an injection moulding process or by a glass-fibre lamination process. If, in the case of such a plastic component, an additional, closed-off storage space was hitherto necessary, additional components had to be positioned and assembled for delimiting the storage space, the outlay being disproportionately high, in particular in the case of series production on the conveyor belt. It is now provided according to the invention for the plastic component to be designed integrally with a container lid made of the same plastic material and for the container lid to be connected to the plastic component by means of a hinge co-formed during the production and for the container lid to be foldable about the hinge after its production and then to delimit the closed-off storage space.
Patent DE-3611301-A1 (DE)
Inventor: EIZENHOEFER ALFONS DR ING
IPC: H04W48/12
Filed: 1986-04-04
Abstract: In prior cellular radio transmission systems a base radio station (BS) periodically transmits references identifying control channels associated with such base radio station, references identifying control channels of adjoining base stations, and references identifying a substitute control channel. The invention reduces the number of references which must be transmitted by a base station, which is of particular advantage in an integrated services cellular radio transmission system. A transmission channel of each base station is assigned as a simplex message transmission channel (COCH) in which a given base station (BS) transmits to the mobile stations (MS) information describing the structure of the control channels (CCH). Such information includes references (NC) to message transmission channels of adjoining base stations and references (CC) to one or more control channels assigned to the given base station. Since the message transmission channels are at a higher level in the hierarchy of references than the control channels, access by several different kinds of subscriber sets and different services can be provided by transmitting a relatively small number of references.

Title: Starting crank for the hand-starting of internal combustion engines
Inventor: KOENIG FRITZ DR
IPC: F02N1/02
Filed: 1986-07-23
Abstract: A crank arm (14) is pivotably mounted on a starting shaft (10). The drive connection is made by way of a coil spring (32), connected to the crank arm (14), which spring tightens on the starting shaft (10) if its other end (36) is held fast by a mechanism (42) on the starting shaft (10). This occurs when the starting shaft (10) is turned in the starting direction (arrow). If the starting shaft (10) starts in the opposite direction or a compression surge cannot be overcome by the torque applied, the coupling between the mechanism (42) and the starting shaft (10) is released by a relative movement between the starting shaft (10) with mechanism (42) and a casing (12) pivotably mounted on the starting shaft (10). <IMAGE>

Title: Device for setting the slack in a safety belt which is wound up automatically
Inventor: SCHOLZ HANSJUERGEN DIPL ING
IPC: B60R22/19
Filed: 1986-09-04
Abstract: A device for setting the slack in a safety belt which is wound up automatically in motor vehicles has two clamping jaws which are situated on opposite sides of the belt and a clamping jaw drive for clamping the belt and for moving the belt a predetermined distance in the direction in which the belt is pulled out. To obtain a robust belt clamping action with a high degree of acceptance of tensile forces, the clamping jaws are held so as to be longitudinally displaceable in guides which are parallel to the direction in which the belt is pulled out and have a predetermined length. One of the clamping jaws takes the form of a two-armed lever, one arm of which interacts with the other clamping jaw to clamp the belt, and with the other arm of which there engages the clamping jaw drive with a driving direction which is parallel to the clamping jaw guides.
Patent DE-3632394-A1 (DE)
Title: Method and device for constructing a noise protection element
Inventor: HAERTLING FRANZ DIPL ING
IPC: E01F8/00
Filed: 1986-09-24
Abstract: The invention relates to a noise protection element comprising a layer of sound-absorbing lightweight concrete, e.g. no-fines concrete, which faces the source of noise and is provided with profiles, and a layer, supporting said layer, of normal concrete with dense texture. According to the invention, such different concrete layers can for the first time be cast in the green state onto one another in immediate succession, the two layers subjected to vibrating movements of the casting mould forming a virtually inseparable unit. The method is carried out with the aid of a casting mould whose cover is in the shape of a grating. Before the mould cover is placed on, the constructional concrete of dense texture is poured in; immediately thereafter, the mould cover is fitted, and the lightweight concrete follows through the open spaces between the grating bars. Since the grating bars have a substantially V-shaped profile, and to be precise with the rounded V tip pointing towards the bottom of the casting mould, the cast-in lightweight concrete is continuously pushed firmly against the profile sides under the vibrating pressure when the concrete level rises, and no air cavities can form.
