Patent DE-3640758-A1 (DE)
Title: Brake slip control device
Inventor: SCHORN MICHAEL
IPC: B60T8/32
Filed: 1986-11-28
Abstract: In a brake slip control for a vehicle brake system with a brake booster (11), the brake pedal (22) has hitherto been hydraulically returned into a certain position by a return sleeve (39) carrying a sleeve seal (44) at the onset of slip control, in order to ensure a brake pedal reserve travel in the event of a failure during the slip control. The start of return has hitherto made itself evident by a disturbing kick-back on the brake pedal followed by a further damped return. The rapid return movement of the return sleeve until the cup seal (44) acting as non-return valve closes is to be regarded as the cause of the kick-back. In order to prevent this kick-back on the brake pedal it is now proposed that by the time control commences and the sleeve seal comes to rest (closes) the return sleeve be brought into a position in which it has no contact with the booster piston and thereby the brake pedal. Only once the sleeve seal is applied and the further return is damped does the return sleeve strike the booster piston in order to return this and the brake pedal. <IMAGE>
Patent DE-3641289-A1 (DE)
Inventor: KNOPF ALOIS DR
IPC: H01Q15/14
Filed: 1986-12-03
Abstract: A process (2) for camouflaging the inlets (1) of power units of aircraft and the like against detection by radar is disclosed. To reduce the global radar cross-section of the aircraft as a whole, the openings of the power unit inlets (1) are subdivided by appropriate radar-reflecting, air-permeable structures into several cells (3) or channels with smaller openings, which on the one hand owing to their dimensions do not allow the incident electromagnetic waves to penetrate into the power unit inlet (1) but reflect them as on a conductive plane, and which on the other hand oppose a minimum friction drag to the air stream.

Title: Collection and transport container for used batteries and used accumulators
Inventor: PRAUTZSCH HERBERT
IPC: B65F1/02
Filed: 1987-01-07
Abstract: A collection and transport container, consisting primarily of a special steel trough, for used batteries and used accumulators has a trough lining, made of acid-resistant and shock-absorbing material, which can consist, in particular, of plastic sheeting or wooden planks in order both to insulate the trough against residual currents and to protect it from shocks occurring when the batteries or accumulators are thrown in. In containers having a pivoting flap at one end face, an oblique threshold plate, merging into the remaining trough bottom parallel to the pivoting plate, and a seal interacting with the door-side edge of said threshold plate are advantageously provided. The undesired escape of liquids leaking from batteries or accumulators is thus prevented.

Title: Dung-transporting system for removing manure from barns
IPC: A01K1/01
Filed: 1987-01-14
Abstract: Dung-transporting system for removing manure from barns in batches via a rectilinear excrement channel which leads out of the barn into the open. It was known, in a cuboidal pressure chamber, at the outlet of which there is formed a dung deposit, to compact the manure, transported into said chamber, by means of the front slide, which is of lower height than the chamber. The disadvantage with this is the high force and energy outlay for the slide movement as well as the low degree of compaction despite said high outlay. The object was thus to provide a system (see 1) such that the dung deposit contains highly compacted manure, and as low an energy outlay as possible is required. For this purpose, the invention proposes to construct the pressure chamber (16) from a rear compaction portion (16.1), which tapers towards the front, and a front, cylindrical compression portion (16.2), this being the known pressure chamber with a reduced cross-sectional surface; to adapt, in outline and in area, the thrust surface of the front slide, configured as a pressing flap (40') which can be received by the compression portion (16.2), and the clear cross-sectional surface of the compression portion (16.2) to one another; and to allow the forwards displacement of the pressing flap (40') [lacuna] to pass one into the other at least as far as the transition (16.3) of the two chamber portions (16.1 and 16.2). The advantage of this is that, by virtue of the initially gradual and ultimately strong compaction of the manure, which has been transported into the pressure chamber (16), by means of a small-surface-area ...

Title: Energy exchanger
Inventor: KELLER JAKOB DR
IPC: F04F13/00
Filed: 1987-02-21
Abstract: The pressure-generating element of the energy exchanger is an energy exchanger runner (17) with a central centrifugal blade ring as the compressor section (19) and turbine blade rings (18', 18'') provided on its sides. A part of the gas serving as the working fluid, usually air, that enters the turbine blade rings (18', 18'') at a pressure p2 is compressed after the rings in the compressor section to a pressure p3 > p2. The remaining part of the gas, that has expanded in the turbine section to a pressure p1, leaves the energy exchanger through the outlet ducts (5, 6). In conjunction with an air-cushion bearing (10) fed by the high-pressure gas duct (25) and a contact-free centrifugal sealing device (26 to 30; 32 to 36), such an energy exchanger operates with great efficiency. <IMAGE>

Title: Three-position directional valve
Inventor: STOLL KURT
IPC: F16K31/126
Filed: 1987-03-07
Abstract: What is proposed is a three-position directional valve with a first valve member (17) which can be controlled by an actuating member (22, 23), is arranged in a valve housing (16) and is held in a first switching position by the force of a first spring (10), all the valve connections (A, P, R) being separated from one another in a second switching position of the valve. The valve connections (A, P, R) are connected to a valve chamber (27) via channels (12, 13, 14), a first of these channels (14) extending in the first valve member (17). In the second switching position of the valve, the mouth of the first channel (14) on the first valve member (17) comes into sealing bearing contact with a second valve member (30) which is held by a second sparing (11) in a position closing at least a second of these channels (13) relative to the valve chamber (27). In a third valve position, the second valve member (30) is held by the first valve member (17) in a position in which the second channel (13) is opened. With a separate setting of their spring force, two springs (10, 11) are each assigned a setting member (34, 35) limiting the maximum spring length. As a result of the simple method of the separate setting of the spring forces, the two switching points can be set independently of one another in virtually any way, so that a highly variable switching hysteresis can be predetermined. <IMAGE>

Title: Arrangement of rotatable levers in sensors which are activated by being sensitive to acceleration, of safety belt retractors
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/34
Filed: 1988-03-14
Abstract: In the case of automatic retractors which are installed at an angle, the problem is that axial force components, which have to be laterally supported, act on the sensor levers owing to the forces H resulting from inclination. When the levers are activated, a hinderance is posed by frictional moments which cause the responsiveness of the sensors to increase disproportionately. To remedy this problem, it is proposed that the downwardly inclined bearing neck 15 of the sensor levers 2 take the form of conical points or round heads, so that support is provided at points along the pivot axis A. The distance 4 provided for this in the design ensures that no disadvantageous frictional moments are produced and that the responsiveness of the lock initiation system of the automatic retracting device can be maintained within the prescribed standards. <IMAGE>

Title: Suction nozzle for turning down end papers
Inventor: THRANDORF HANS-PETER
IPC: B42C5/00
Filed: 1988-06-07
Abstract: The invention relates to a suction nozzle for turning down end papers for use in the gluing of end papers within an adhesive binding machine. Suction nozzles (4) are pivotably arranged on both sides of the book block transportation system (3), and their pivoting movement takes place under clock control. The clock control is set to the front edge of the end paper. If this deviates from the front edge of the book block, a pivoting movement of the suction nozzles (4) together with the end papers (2) does not take place until the suction nozzle apertures (7) are covered by the end papers (2). The effect of this is to prevent projecting contents sheets of the book block (1) from being picked up by suction, which would result in rejects. <IMAGE>
