Title: Hydraulic pressure-control arrangement, in particular for power shift gears of motor vehicles
Inventor: LOEFFLER ALFONS
IPC: F16H61/00
Filed: 1988-03-26
Abstract: A hydraulic pressure-control arrangement, in particular for power shift gears of motor vehicles, contains a pressure-medium pump (1) and a main pressure valve for the pressure control in at least one high-pressure consumer (6), which is connected to a pressure line (3) between the pressure-medium pump (1) and the main pressure valve. The main pressure valve is designed as a pressure-relief valve. The function of a second pressure-relief valve is integrated in the main pressure valve. By two compression springs (17, 18) connected in parallel, of which one compression spring (18) is captivated, two pressure limit values of different magnitude can be set in the pressure line (3) by a valve piston (21). <IMAGE>

Title: Device for connecting a liquid-crystal display element to a flexible cable
Inventor: TOMOFUJI MAKOTO
IPC: G09F9/35
Filed: 1988-04-18
Abstract: In a device for connecting a liquid-crystal display element to a flexible cable which leads to an external device, continuous openings are provided in the flexible cable in the region between the connecting electrodes and having a pre-specified separation from one another, these openings extending in the longitudinal direction transversely to the end of the lower glass carrier wafer, when the cable is mounted on the lower glass carrier wafer. The resin serving for the connection then spreads out over the upper surface of the cable close to the upper glass carrier wafer, also over the end surface of the latter, flows over the openings to the rearside of the cable, spreads out over the undersurface of the cable close to the end of the lower glass carrier wafer and over the end surface of the latter. The resin can thus spread out not only over the upper and lower surfaces of the flexible cable, but also over the respective end of the surfaces of the upper and lower glass carrier wafers and, indeed, advantageously by means of only one operation using the resin.

Title: Piston roller bearing for absorption of the radial forces on axial flow rotary engines
IPC: F01B31/04
Filed: 1988-09-22
Abstract: The centrifugal forces occurring in the double pistons (7) rotating about the engine centre axis (2) are absorbed by roller bearings (12) in accordance with Figs. 1, 2 and 3. The double pistons (7) rotating about the engine centre axis (2) roll on the cam track (5) fixed to the engine housing (1). At the centre, that is at the centre of gravity, the said pistons have a rod head (11), which is screwed into the bushing (14). The inward end of the rod head (11) facing the engine shaft (6) has a pin (13) pressed in, on which 2 roller bearings (12) are fixed on either side. On the engine shaft (6) facing each cylinder liner (4) a pair of brackets (10) is arranged, on the inside of which the roller bearings (12) can be supported against centrifugal forces of the double pistons (7). On the pairs of brackets (10) the inside of the rolling surface for the roller bearings (12) is as long as the stroke of the double pistons (7). The double pistons (7), rotating on the pitch circle (3) and moved axially in the cylinder liners (4), are guided on the cam track (5) by the rollers (8) so that, for one revolution about the engine centre axis (2), they run through a full working cycle of 4 strokes on a sinusoidal cam centre line (9). <IMAGE>

Patent DE-3916711-A1 (DE)
Inventor: DEBUS KLAUS D DIPL ING
IPC: B60C11/16
Filed: 1989-05-23
Abstract: Broad tyres have one or more deep longitudinal grooves (12) penetrating as far as beneath the belt region (2) inside the tyre with the aid of novel bridging components (5). Drainage is maintained even at the starting limit and increases overall economy. It is possible with this deep-groove technology to build anti-aquaplaning tyres, including racing and aircraft tyres and also better ''M+S'' (snow) tyres. A special embodiment makes the pneumatic insertion and removal of aids to traction like spikes, etc., a simple matter. This permits the manufacture of completely novel M+S or all-year tyres. Additional steps permit the use of three-ply tyres. Special designs make it possible to use them as or in emergency running gear. Besides tyres, air-sprung bearing rollers for cable cars and lifts can use this deep-groove principle.

Title: Cleaning and prepn. of hoed crops - by continuous process in which part of process water is constantly removed and replaced by similar quantity of fresh water
Inventor: GERLACH KAY DIPL ING
IPC: B03B9/00
Filed: 1989-06-08
Abstract: In a conventional batch process for prepn. of hoed crops, the crops pass through a water-filled channel to a sepn. unit, where fine particles are removed. All the water used is collected in a large separator and after removal of the solid particles is returned to the channel. An improved continuous process is described in which part of the water is constantly exchanged for new water. The process water does not have to spend time in a separator therefore a continuous process using less water is realised. USE/ADVANTAGE - For cleaning and prepg. potatoes, carrots, celery, onions and similar vegetables. Solid matter is easily removed from the vegetables, the process is continuous and uses less water.

Abstract: A cutting tool (10) has a basic body (11) in which at least one cutting tip (14) is arranged in such a way that it can be adjusted and fixed in position. An eccentric (25) rotationally adjustable about its longitudinal axis (26) sits in the basic body (11). The eccentric (25) bears against the cutting tip (14) and supports it with regard to the basic body (11). The eccentric (25) is in turn held in such a way as to be adjustable transversely to its longitudinal axis (26). The eccentric (25) is supported on the basic body (11) by means of two supporting bodies (32, 33). One supporting body (33) supports the eccentric (25) at an end area, while at an axial distance therefrom the other supporting body (32) with an eccentric part (40) thereon can make a swivel adjustment to the eccentric (25). Thus, in addition to a radial and/or axial adjustment of the cutting tip (14), the taper of the cutting tool (10) can also be changed. <IMAGE>

Title: Thyristor with high barrier effect in blocking direction - has P-emitter lateral dimensions for its location within thyristor central region
Inventor: SCHULZE HANS-JOACHIM DR
IPC: H01L29/08
Filed: 1989-09-28
Abstract: In order to increase the barrier capacity of the thyristor in the blocking direction, the p-emitter (4) is limited to a central section (LBz) of the thyristor. It forms a  continuous layer, while the edge termination (10) of the pn-junction (7) lies between the p-(2) and n-base (3) in the  thyristor edge region (LBr). The region is laterally outside the central region. Alternately, the p-emitter can extend laterally over the entire surface of the thyristor, when a stop zone (11) of the n-base is provided. The zone has different doping profiles in both regions such that the intersection point concentration at its pn-junction to the p-emitter is higher in the lateral edge region than in  the central one. ADVANTAGE - Simple structuring for barrier tendency attaining.
