Patent DE-3411261-A1 (DE)
Title: Hydraulic, two-stage actuating arrangement for a servomotor
Inventor: POLACEK BOHUMIL DIPL ING
IPC: B62D5/22
Filed: 1984-03-27
Abstract: The subject matter of the invention is a hydraulic, two-stage control arrangement for a servomotor. The control arrangement is intended in particular for vehicle steering and is fed together with a further hydraulic motor from a common hydraulic pump. All functions, namely the flow control, the flow intensification and the braking of the negative load, are ensured by a small number of components at relatively small pressure losses through the fluid choking and with maximum operating reliability. According to the invention, these advantages are obtained by the spool valve, the flow intensifier and the chokes being designed as a simple spool unit with simple short passages. <IMAGE>
Patent DE-3418384-A1 (DE)
Title: Devices for speed-independent delivery regulation combined with energy recovery in constant-delivery pumps - especially in lubricating-oil pumps
Inventor: INGELHEIM PETER GRAF VON
IPC: F04C15/06
Filed: 1984-05-17
Abstract: According to the invention, either pressure-limiting valves making use of the injector effect and thus increasing the suction-side pump pressure are incorporated in such a way as to result in a high benefit/cost relation, or special pressure-limiting valves are incorporated in such a way that their jet pressure increases the torque at the pump. Another possibility is to recover energy with the aid of a Segner wheel.
Patent DE-3418654-A1 (DE)
Title: Electromagnet for a valve
Inventor: BARTHOLOMAEUS REINER DIPL ING
IPC: H01F7/16
Filed: 1984-05-18
Abstract: In an electromagnet for a valve, the armature space under the pressure of the fluid is closed off relative to the winding of the electromagnet in the air gap by a pressure-tight seal which consists of a flange-like component and sealing rings. This improves the pressure-tight seal and higher internal pressures can be sealed off without hydraulic forces acting on the winding. <IMAGE>

Title: Beet cleaner
Inventor: LANG WINFRIED
IPC: A23N12/00
Filed: 1984-07-06
Abstract: The beet cleaner is used in agriculture when the beets have been mechanically dug up, but before they have been laid in. Its object is to clean off leaves and earth adhering to the beets in the wet and dry condition, in a gentle and thorough manner. The beets tipped into the feeding hopper are transported towards the vertically adjustable slide and subjected to preliminary cleaning by the supporting rods of the endless conveyor which circulate underneath the beet and are arranged noncontinuously, the beets permitted to pass underneath the vertically adjustable slide being fed in a metered fashion to the rapidly rotating cleaning roller and pressed against the latter. Leaves and earth adhering to the beets are removed by the rotation of the cleaning roller, and the beets are simultaneously moved by the shape and arrangement of the cleaning roller, transversely to the conveying direction of the endless conveyor, to the feeding chute. From the feeding chute, the beets are fed into the storage space, either directly or via a conveyor belt arranged downstream.

Title: Display device for the oil replacement intervals in internal-combustion engines
Inventor: ZABLER ERICH DIPL ING DR
IPC: B60R16/02
Filed: 1984-08-21
Abstract: A display for the oil replacement intervals in internal-combustion engines is proposed, two surfaces (11, 12) which form a capacitor (10) being provided in the oil circuit of the internal-combustion engine and/or the transmission of the internal-combustion engine, between which surfaces (11, 12) the oil forms the dielectric. In order to detect the equivalent resistance, an AC voltage source (18) having a frequency of preferably 200 Hz is connected to this capacitor (10). The equivalent resistance, or a variable derived therefrom, is supplied to a display device as a measure of the aging of the oil or of the oil quality. In this way, the oil condition can be determined very exactly, and longer service intervals can be achieved by avoiding unnecessary oil replacements. <IMAGE>

Title: Process for welding preformed plastics connection sockets to the associated free ends of plastic pipes
IPC: B29C65/20
Filed: 1984-09-15
Abstract: The invention relates to a process for welding preformed plastics connection sockets to the ends of plastics pipes. The clear width of the connection socket corresponds to the outer diameter of the plastics pipe and the connection socket is pushed onto the free end of the plastics pipe. According to the invention, in a first operation the connection socket is fused from the outside in a surrounding manner in an annular circumferential groove by the supply of heat. In this operation the fused region is extended as far as into that surface of the plastics pipe which is associated with the circumferential groove. In a subsequent second operation, the partial regions of the connecting socket which are separated at least partly by the circumferential groove are welded in the region of the fusion by axial compression with the simultaneous elimination of the circumferential groove. In this manner a liquid-tight and gas-tight connection between the connection socket and the plastics pipe is obtained.

Title: Drop-forging with asymmetric precavities
Inventor: SULC MILOSLAV DIPL ING
IPC: B21J5/02
Filed: 1984-12-05
Abstract: The subject-matter of our invention is the reduction of the excess material used by an amount  DELTA V', this being achieved by the use of so-called asymmetric precavities. The use of these asymmetric cavities ensures uniform volume distribution of the material used in the cavity. With asymmetric cavities, it is possible in the most favourable case to save approximately half of the excess material used hitherto, making up about 10 to 20% of the total weight (e.g. in the production of crankshafts).

Title: Method for producing colour pictures
Inventor: MEINTZ HELMA
IPC: H04N1/46
Filed: 1985-07-22
Abstract: The invention relates to a method for producing a colour picture, in which a colour negative is produced from a colour original, and the colour picture is exposed from the colour negative in a copier or printer onto a colour print material. The colour original is decomposed into colour values pixel by pixel, and the colour negative for the copier is exposed, using an electronic colour recorder controlled by the colour values, pixel by pixel and row-wise onto the colour print material provided for producing the colour pictures. The method has the advantage that the customary production of a colour intermediate negative for the copier is eliminated, and that the setting parameters for the colour recorder can be matched during the exposure of the colour negative in an optimum way to the properties of the colour print material, of the printer and of the developing process.

Title: Apparatus for lining tunnel tubes or galleries with pumped or air-placed concrete
Inventor: KITTLASS KLAUS
IPC: E21D11/10
Filed: 1985-08-28
Abstract: In an apparatus for lining tunnel tubes or galleries with pumped or air-placed concrete by means of a reciprocating-piston concrete pump, the concrete placement funnel is closed with a cover plate to which a suction line with a suction unit is coupled. Here, via a preloading container which can be coupled to and uncoupled from the suction line, the concrete can be received in a remote concrete mixing plant and, after coupling to the suction line, can be discharged to the funnel. Thus in the case of a stationary concrete pump recourse can be had to simple means for advancing the concrete; in particular no extensions of concrete-feed lines are necessary. <IMAGE>
