Title: Hydraulic brake system with ABS and wheelspin control - isolates brakes by switching valve with integral pressure relief valve
Inventor: WETZEL GERHARD DIPL ING
IPC: B60T8/48
Filed: 1991-04-13
Abstract: The wheel brakes are separated from the master brake cylinder (14) by a switching valve (45). A hydraulic pump (38) on the wheel brake side of the valve provides the control pressure, excess pressure being ducted back to the master cylinder reservoir (15) via a relief valve. Both valves are integrated into a single control slider for a compact layout. The single slider action ensures that the valve elements of the relief valve move a significant distance between inactive and active positions. This ensures that the valve seatings are flushed and do not dry. ADVANTAGE - Compact lay-out; self cleaning valve action.

Patent DE-4130055-A1 (DE)
Inventor: HOBELSBERGER JOSEF
IPC: B44C1/22
Filed: 1991-09-10
Abstract: A pair of ice bodies each have a planar surface which are warmed to melt the surface. Then at least one of the surfaces is provided with a cavity engendered by the application of a dimension controlled heat source, suitably by engraving with a heated relief formed die-like tool having a metal engraving element of a given design. The engraving element is warmed above the ice melting temperature and brought into contact with a planar surface of the surface of the ice body so that the element melts away portions of the ice body in the area of the element and the melt water is simultaneously removed by gravity, a vacuum or by a blast of cold air. When the desired engraving depth has been attained, the planar surfaces of the ice bodies to be mated are wetted by warming and are pressed together and if needed, cooled to freeze the interface producing an assembled ice body with an internal engraving and a transparent seam. Both bodies can be engraved in mirror image fashion with the engravings aligned and mated to form a single engraving in the composite body. The engraving brilliantly stands out from its surroundings in a drink medium because of the different light refractive indices.

Title: Packet oriented transmission for digitally coded speech information - using counter to control read out of buffer memory for temporary storage of transmitted information packets.
Inventor: DIETER GEORG DIPL ING
IPC: H04J3/06
Filed: 1991-09-30
Abstract: The method involves forming digitally coded speech information to be transmitted into packets using speech pause information. The transmitted speech information packets received from the transmission system (UES) are stored temporarily in a buffer memory (PA), from which they are read out depending on the momentary value held in an associated counter (ZA). The latter is synchronised with the transmitted information packets and the packet propagation time variations. Pref. a difference value is provided between the momentary count of a reception counter (EZ) and the running number of each packet, upon its reception by the buffer memory. A mean value is formed from the successive difference values used to set the value of the counter controlling read out of the buffer memory. ADVANTAGES - Ensures correct sequence of transmitted information packets.

Title: Abrasive water jet gun - has wet sand feed pipe with opening through which surrounding air is drawn to mix with sand and reduce viscosity, thereby improving jet efficiency
Inventor: SCHMIDT WILHELM
IPC: B05B7/14
Filed: 1992-03-23
Abstract: The gun has a cylindrical body (12) with a chamber (10). A nozzle (14) at the inlet end of the chamber admits water at high pressure and at the outlet end is an exit nozzle for the sand and water mixt jet.

Title: Paper web shear force valve determn. - uses signals for speed and web tension on either side of a clamping point to give a valve correlated to web width
Inventor: GOETTSCHING LOTHAR PROF DR ING
IPC: G01L5/10
Filed: 1992-06-30
Abstract: To determine the value of a shearing force on a web, related to its width, without damage to the paper, signals are registered showing the web speed and draw tension on the web before a clamping point and after it. The signals are processed electronically to give a value for the lateral breaking load. The signals are pref. registered at two guide rollers, before and after the web clamping point. To establish the absolute breaking force, the index value is multiplied by a correlation factor set onece only for a papermaking or finishing machine by comparison with static shear tests. The index value signals are registered simultaneously to give a series of values for a breaking force value. The evaluation unit can transmit an index value signal to a process control unit connected to it. USE/ADVANTAGE - Used for setting an index number correlating to the paper breaking force related to its width in a papermaking or paper finishing machine to show the speed at which a printing press can be operated without web breaks for packaging machinery. The operation gives an index number for the paper material established without damage to the web.
