Title: Ball valve
Inventor: JAEKEL HORST DIPL ING
IPC: F16K5/06
Filed: 1987-01-23
Abstract: A description is given of a ball valve with at least one inlet and one outlet for a fluid medium. The said ball valve has a spherical plug (7) which is rotatably mounted in a housing (15) and is connected to an operating element (8) passed out of the ball valve. Annular pistons (22, 23) are arranged adjacent to the spherical plug, upstream and downstream of the latter, along the flow path of the medium. To support the spherical plug concentrically with respect to its axis of rotation, bearing flanges (9, 18) are provided coaxially to the said axis. A seal is provided between the annular piston and the spherical plug both on the inlet and on the outlet side. The annular pistons hold the spherical plug in a defined position in the direction of its axis of rotation. Sealing between the annular pistons and the spherical plug is preferably achieved by means of compressed graphite rings (26, 27) which press the annular pistons against the spherical plug. <IMAGE>

Title: Fuel injection pump for internal combustion engines
Inventor: RIESENBERG KLAUS DIPL ING DR
IPC: F02M59/36
Filed: 1987-01-31
Abstract: In order to reduce the combustion noise from a diesel internal combustion engine, the injection period in a fuel injection pump is extended in that at low speed and low fuel delivery the start of fuel delivery is controlled. In order to obtain a short injection period at full load or high engine speed, the end of fuel delivery is controlled. For this purpose, the pump piston (14) has two control bores (24, 25), arranged at a distance from one another, which are covered by a control slide valve (26), are axially displaceable on the pump piston (14) and are closed or exposed in the course of the pump piston stroke according to the position of the control slide valve (26). The control slide valve (26) is adjusted from start of delivery control to end of delivery control between two injections. <IMAGE>

Title: Holding-down device
IPC: B23Q3/00
Filed: 1987-10-03
Abstract: A drive unit (4) with a spiral drill bit (2) is fastened on its annular plate (5) which can be raised and lowered with respect to the longitudinal axis (15) and a holding-down device (6) is guided resiliently, in parallel with the vertical. The holding-down device (8) is supported on the workpiece (1) via plate springs (18) by means of support balls (25) and forms a holding-down housing (20) with a rotationally symmetrical machining space (23) which is closed all round and surrounds the drill bit centrically. Said machining space (23) has at the bottom a blowing annular channel (29) with slot-shaped blowing nozzles (27) and, thereabove, an annular suction nozzle (28). In this arrangement the blowing medium is blown centrically obliquely downwards and inwards onto the workpiece and bit and is completely taken up by a stronger suction flow, entraining the swarf. The drill bit and workpiece are thus reliably cooled and cleaned in the engagement region and all swarf is immediately conveyed outwards and in the process cooled itself. <IMAGE>

Abstract: The cylinder head, with a common gas-reversing valve for the inlet and outlet of an internal combustion engine and the control of the gases by an asynchronous rotary valve, is completely new in its design. It is exclusively for 4-stroke engines. The special features of this head lie   1. in the virtually pressure-free area of the gases at the asynchronous rotary valve, 2. in the thermal balance of the hot outlet gases and of the cold inlet gases which act on the asynchronous rotary valve and the hollow valve, 3. in the angular velocity of the asynchronous rotary valve during the gas reversal, which is at the maximum, 4. in the prevention of an exhaust gas return by the asynchronous rotary valve during the gas reversal, 5. in the twist movement of the inlet gases which is forcibly formed,   6. in the advantages of the toothed-belt drives for the asynchronous rotary valve,   7. in the development of the hollow valve,   8. in the possible omission of the spur gear box, 9. in the incorporation of the injector for diesel engines into the cylinder head, 10. in the great gas passage cross-sections available for the optimum breathing of the engine.   Lastly, it is to be mentioned that this cylinder head is intended to increase the charging of an internal combustion engine up to the possible hollow valve capacity.

Title: Process for fabricating solar cells from amorphous silicon having enhanced sensitivity to blue
Inventor: KARG FRANZ DR RER NAT
IPC: H01L31/075
Filed: 1987-12-16
Abstract: In order to enhance the sensitivity to blue and thus the efficiency of pin or nip solar cells made of amorphous, hydrogenised silicon on transparent substrates (1), the dopant carry-over due to the previously deposited p or n layer (3) is compensated for, during the deposition of the i layer (4) in the glow discharge plasma by a dopant of the opposite conductivity type. In the case of pin solar cells, the boron profile inevitably occurring in the i layer (4) is compensated for by a parallel phosphorus doping profile. <IMAGE>
Patent DE-3812233-A1 (DE)
Title: Water valve
Inventor: OTT WILFRIED
IPC: F16K31/50
Filed: 1988-04-13
Abstract: In water valves, there is the risk that the valve seat and/or the tapered valve plug will be squeezed and therefore damaged if the valve spindle operating the tapered valve plug is overtightened. To avoid the squeezing of the seal in the valve seat or in the tapered valve plug, an anti-rotation safeguard can be provided. In the case of correct operation of the water valve, this allows the stroke motion of the tapered valve plug without hindrance but, if the valve is closed with too much force, the anti-rotation safeguard is released and ensures that the tapered valve plug cannot come down any further onto the valve seat. The reliability of the anti-rotation safeguard is achieved by the fact that it is designed as a flexible spline system. The low dimensional tolerances required for particular reliability and long-term stability are achieved by virtue of the fact that the housing, on the one hand, and the tapered valve plug together with a valve piston, on the other hand, are of integral construction. This also considerably reduces the outlay involved in manufacture and assembly.

Title: Container, in particular for small attachment parts
Inventor: MUNZ WALFRIED W
IPC: B65D5/44
Filed: 1988-06-30
Abstract: The container (10) has a cuboid bottom part (11) and a hinged covering lid (12) which is attached to the linked side wall (16) via a hinge (13) and whose front wall (20) covers the front side wall (17) of the bottom part (11) of the container over a large area. Triangular wall parts (48.1, 48.2) and reinforcement webs (45.1, 45.2) serve to reinforce the lid (12) and engage over the end side walls (18.1, 18.2) from the outside whilst exposing a window (61) in the end side wall (18.1). Furthermore, a free area (54.1) remains free so that an easily visible label can be attached. A reinforcement and securing edge strip (32) is fastened to the front side wall (17) by folding towards the outside and partial bonding-on in its fixed region (32.3). It is overlapped by an edge strip (34) of the lid, such that the cut edges (56.1, 56.2) form an opening securement which automatically becomes effective when the lid (12) is closed. This can be overcome for opening by pressing a finger through the gripping cutout (40). <IMAGE>
