Title: Reversing device
Inventor: BRANDENBURGER WALTER ING
IPC: F15B11/15
Filed: 1985-01-23
Granted: 1986-03-13
Abstract: The invention relates to a reversing device for a double-acting piston/cylinder unit, in particular for hydraulic reversible ploughs, with a control piston and an auxiliary piston arranged inside the control piston for obtaining a small effective area. The control piston of a known construction has such a small overlap between the feed and the control space effecting the reversing that considerable leakages flow into the control space and have to be drawn off via comparatively large restrictors. This results in considerable flow losses during full pressurising of the control space. To avoid this phenomenon, the small auxiliary piston, according to the invention, is provided with a control edge which opens the connection to the control space after a certain stroke of the control piston. The control piston itself has a large overlap so that the leakage remains slight.

Title: Warhead
Inventor: HESSBERG HELMUT DR
IPC: F42B12/22
Filed: 1985-12-11
Granted: 1987-07-02
Abstract: In the case of a warhead, a thin-walled lining (3) is provided between the casing (1) and the explosive charge (2) in order to break the casing (1) up into fragments of specific mass. The lining (3) consists of a multiplicity of webs (6) which have a cross-section shaped like a house. When the explosive charge (2) detonates, a cutting jet (13) which breaks up the casing (1) is formed from the ridged roof (9) of the webs (6). The detonation wave (12) thus no longer runs into any cohesive casing (1) but into separate plates which it accelerates individually as fragments of the desired size. <IMAGE>

Title: Double-disc labyrinth face seal
Inventor: FEY JOSEF
IPC: F16J15/44
Filed: 1987-03-18
Granted: 1988-09-22
Abstract: Double-disc labyrinth face seals 1 of this kind are used to seal off grease-lubricated bearings with axial play, such as those in wheel set bearing arrangements of rail vehicles. The procedure has hitherto been to have the individual double-disc rings 2 rest with a clamping force against the bearing housing 3, the grooves 4 in the seal carrier 5 being of a width which takes into account the axial play of the bearing arrangement. In order to avoid a situation where, under extreme operating conditions such as, for example, very low temperatures, the lubricating grease overcomes the holding torque of the double-disc rings 2, brought about by their clamping force, due to its viscosity and thus takes them along in rotation, in which case they cut into the mating surface 6, the double-disc rings 2 are fitted under a very low prestress and are a sliding fit with the mating surfaces 6. <IMAGE>

Patent DE-3827439-C1 (DE)
IPC: B65H26/08
Filed: 1988-08-12
Granted: 1989-10-12
Abstract: Coils are wound/unwound using an expandable mandrel 2, the coil diameter being monitored to control mandrel expansion. By using an expansion force setting corresponding to the current outer coil diameter overloads are avoided and wear is significantly reduced. As described, a microprocessor 10 determines the initial expansion pressure and determines the required coiling tension from parameters such as coil weight and strip width. A computer 9 maintains the required tension by controlling a mandrel drive motor 8. The coil diameter is monitored by computer 9 and transmitted to the microprocessor 10 to control mandrel expansion pressure by means of a valve 11. <IMAGE>

Title: Recycling amine from sand moulding process - by progressively increasing pH of used gases in solution and removing amine by gravity separation
IPC: B22C9/12
Filed: 1992-07-18
Granted: 1993-09-16
Abstract: Recycling amine used in sand moulding as a hardening catalyst comprises collecting the gas mixture which has passed through the sand moulding to be hardened and dehydrating the aqueous mixt. by adding a strong alkali which renders the amine less soluble in water. By gravity separation the dehydrated amine is separated from the lead solution and distilled to remove residual processing contaminant.

Title: Inclination sensor for a vehicle
Inventor: WETZEL GUIDO DIPL ING
IPC: G01C9/20
Filed: 1993-06-21
Granted: 1994-10-13
Abstract: The invention relates to an inclination sensor for a vehicle, consisting of a transparent and symmetrically designed vessel which is fixed to the vehicle, the symmetry axis of which vessel is directed parallel to the main axis of the vehicle. The vessel is designed as a hollow body and partly filled with an at least approximately light-transmitting liquid. A light barrier arrangement made up of a central phototransmitter and radially arranged photodetectors monitors the surface level of the liquid. In order to improve the response performance, the upper surface of the hollow body has a recess, so that the vessel is divided into a trough and into a rising vessel. The displacement effect due to the indentation being immersed in the liquid during inclination and the capillary action of a narrow rising vessel contribute to improvement of the response performance.
