Patent DE-3108517-A1 (DE)
Title: Plastic sealing cap
Inventor: HEINLEIN HANS
IPC: B65D41/34
Filed: 1981-03-06
Abstract: In the case of a plastic sealing cap (1) which is provided with an inside thread (2) and has a sealing ring (7), which is shaped by a torus, for bottles, in order to prevent axial displacement of the sealing ring, due, for example to gas pressure exerted by the contents of the bottle, provision has been made for at least two webs (10, 13) to be arranged in an annular groove (14), the said webs (10, 13) being integral with the sealing cap (1). The advantages of the solution according to the invention are that the sealing effect to be achieved between the sealing ring (7) and the container is not impaired as a result of the necessary elastic deformation of the outer wall. <IMAGE>

Title: Roll changing apparatus for rolling mills
Inventor: AKITA SHINJI
IPC: B21B31/08
Filed: 1981-10-20
Abstract: The invention relates to a roll changing apparatus for rolling mills, by means of which seamless steel tubes or the like can be produced. The apparatus has a pair of guide girders (5a, 5b), which are arranged on a supporting block (3) and can be moved parallel to one another, a multiplicity of roll carriages (1a, 1b, ..., 1q), each of which has a set of roll rollers (13a, 14a), and a device for moving the roll carriages, in which two or more roll carriages are in each case arranged on the guide girders (5a, 5b) and at least one of the roll carriages (1a, ..., 1q) can be moved forwards on the respective guide girder (5a or 5b respectively) to form a rolling mill. If the roll carriages are to be changed, the roll carriages (1a, ..., 1q) which have been moved forwards are moved backwards on the guide girders and the other roll carriages (1b, ..., 1p) are then moved forwards in order in this way to achieve an automatic changeover of the roll carriages within a short time. <IMAGE>
Patent DE-3141877-A1 (DE)
Title: Vehicle wheel
Inventor: LOEPER BERND
IPC: B60C17/04
Filed: 1981-10-22
Abstract: In a vehicle wheel consisting of a single-part rim and tubeless tyre, the tyre beads are equipped with a bead toe which is located, viewed from the transverse centre of the tyre, on the outside of the bead and engages in an annular rim groove which forms part of a bead bed which also comprises a rim shoulder on which the other part of a tyre bead rests. The external groove wall of the annular grooves of the rim forms the inner wall part of the rim flanges whose outer edge is at a greater radial distance from the rim axis than the rim shoulder. The part of the rim casing located between the rim shoulders protrudes beyond said shoulders in the radial direction. As a result, the rim can be constructed without a drop centre and the part of the rim casing located between the rim shoulders can be constructed as a support ring with good emergency running properties. In addition, the arrangement of the annular rim grooves directly next to the rim flanges permits the outer profile of the rim to be simplified and the tyre to be pulled on advantageously and supported reliably with lateral forces acting effectively on said tyre.

In the region of the jaw of the forceps the gripping arms are equipped with teeth. The lower lever ends carry a locking device which can be blocked in different positions and prevents pivoting of the levers in its locked position. Finger loops are provided at the lower lever ends.
Patent DE-3147543-A1 (DE)
Title: Extendible drawbar
Inventor: LA FORCE EGON DIPL ING
IPC: B60D1/155
Filed: 1981-12-01
Abstract: A trailer for a lorry has an extendible drawbar (28) whose extension length can be controlled automatically by means of a control mechanism as a function of the steering angle of the drawbar. Said steering mechanism is composed of a rotary disc (48) which is mounted concentrically with respect to the bogie and is coupled with gearing to the latter in order to produce rotation in the opposite direction, and of a linkage element (54) which extends from a counter bearing (52) on the disc (48) to a bearing point (58) on the drawbar (28). When the drawbar (28) rotates, the counter bearing (52) migrates on an orbit in the opposite direction and the linkage element (54) forces the drawbar to experience a corresponding extension movement. Preferably, the extension length of the drawbar reaches its maximum at a steering angle of approximately 30-45 DEG  and then becomes smaller again. <IMAGE>

Filed: 1982-02-11
Abstract: A drying device for pulverulent or granular pharmaceutical material is proposed. This drying device has a container (1) which includes a vibrating bottom (11) which receives the product to be dried. As a result of the vibratory movement of the bottom (11), the product to be dried is continuously conveyed from an inlet opening (3) to an outlet opening (5) of the container (1).

Title: Method of producing a rolling-bearing unit
Inventor: BRANDENSTEIN MANFRED
IPC: F16C33/64
Filed: 1982-08-10
Abstract: In a method of producing a rolling-bearing unit which has track rings concentric to one another and having tracks for the rolling bodies, fastening lugs or the like, projecting radially on at least one track ring, are provided for fastening adjacent parts to this track ring, and the track ring is hardened in the area of the tracks. To avoid distortion during the hardening and the disadvantages associated with this, the track ring is first of all produced as a basic body with an outside diameter which corresponds to the radial extent of the fastening lugs, notches being impressed along the desired final outer contour of the track ring at both end faces of the basic body. The basic body provided with the notches is hardened in the area of the tracks, and, after the hardening, the areas of the basic body which are located radially outside the notches between the fastening lugs are broken away.
Patent DE-3233832-A1 (DE)
Title: Oil-fired gas turbine with oil-air mixture injection
Inventor: ZIMMERMANN HANS GEORG ING GRAD
IPC: F02C7/236
Filed: 1982-09-11
Abstract: The efficiency of combustion in combustion chambers of gas turbines will be improved to nearly 100% and pollutant emissions in the exhaust gas reduced by virtue of the fact that, instead of oil injection, an oil-air mist is injected into the combustion chambers by means of a pressurised-oil pump and an atomiser nozzle. Rotary piston mixture compressors are used to produce the mist. The intake air for the mixture compressor(s) is taken from the delivery flow of the turbine compressor, with the state P2 and T2 (Figure 1 (4)), and a small portion, e.g. 5%, from the quantity delivered by the turbine compressor. An oil metering pump assigned in each case to one mixture compressor delivers the quantity of combustion oil required for the particular power of the turbine into the intake flow of the mixture compressor. The mist formed in the mixture compressor, in the state P3 and T3, flows into a pressure chamber. In the case of turbines having a plurality of combustion chambers - for example an aircraft engine - the pressure chamber is designed as an annular manifold (Figure 1 (3)) and can be supplied by one or more mixture compressors. The injection nozzles (Figure 1 (6)) are connected to the pressure chamber (manifold). <IMAGE>
