Title: Automatic distributor valve controlling oil supply - has spool valve actuated by inlet pressure to apportion pump output between first and second user
Inventor: SCHUMANN GUENTHER DIPL ING
IPC: F15B13/02
Filed: 1990-01-31
Abstract: The valve automatically controls the supply of hydraulic oil to two users, one requiring a steady flow rate and the other a high flow rate intermittently. Oil is supplied from a pump which can be switched from low to high output. The inlet (9), steady user outlet (5) and intermittent user outlet (10) all open into a chamber (14) of the bore (2) in the valve body (1). Sliding in the bore is a spool (12) urged to the left by a spring (13) and having an extension ending in a throttle valve at the outlet (5). When the pump is switched to high output, the pressure in the chamber (14) rises and forces the spool to the right. This uncovers the aperture (11) so that oil cna flow to the user outlet (10). At the same time, the throttle valve is seated so that only just the right amount of oil can continue to flow through small throttle aperture (7`) to a user outlet (5). If the pump is returned to low output, the pressure int he chamber (14) drops and th the spool moves to the left, closing off outlet (10) and opening the throttle to outlet (5). ADVANTAGE - Simple, low-cost system.

Abstract: Support rings (1) are mounted on the wheel rim via a locking nut (3), artificially widening the rim.  They are very stiff axially, resisting tyre side wall pressure, but deform radially when driving over obstructions and in case of a flat tyre.  Cavities (2) in the ring structure aid this function. Upon release of contact pressure the rings return almost to their original position. The weight of the ring is kept low by the use of plastics, alloys and composites for mfr. USE/ADVANTAGE - Wheel rim widening system on vehicle gives improved driving stability and steering precision.  Requires no external system change.

Patent DE-4042303-A1 (DE)
Inventor: SAUER KLAUS DR
IPC: H04L12/403
Filed: 1990-12-31
Abstract: 2.1 The competition for access by stations connected to a bus system should occur independently of the transmission of information and at the same time as this transmission. Before the beginning of the transmission of information items, the order in which the stations are allowed to transmit should already be defined. This is intended to save time when there are many requests. 2.2 In the stations (S1 - Sn), transmitting sequence memories are provided in which the addresses of stations (S1 - Sn) with access authorisation are successively stored. These are used for forming transmission queues. When a station detects its own address when reading out the transmitting sequence memory it can begin to transmit the information. 2.3 Since the competition for access occurs independently of the transmission of information, time can be saved particularly in the case where there are many requests because the transmission of information and the competition for access can occur at the same time. <IMAGE>

Title: Protection of connectors against penetration of flux during soldering - by applying a foil of an adhesive to the underside of the connector and then melting the adhesive to seal gaps between pins and housing
Inventor: FRIEDRICH ANNEGRET DIPL ING
IPC: H01R43/02
Filed: 1991-05-27
Abstract: The sealing of connectors against penetration of flux is carried out by applying a foil of a, pref. thermoplastic pref. of polyimide 0.1-1.0 mm thick, adhesive to the underside of the connector, thereby penetrating the foil with the terminals, and then melting the foil material. After cooling down the adhesive adheres to the underside of the connector and fils up any gaps between the terminals and the housing. Also claimed is the use of a tool with which the foil can be applied. Pref. the tool (8) is made of plastic or metal and contains a cavity (9) with holes (12) in the bottom (10) into which the terminals of the connector fit. The foil is placed on the bottom plane (10), which may have a recess (13) in it with a depth equal to or less than the thickness of the foil, to locate the foil better. The connector can then be placed into the tool whereby the terminals penetrate the foil, and removed taking the foil with it. Holes (11) are provided to allow access to the connector after insertion. USE/ADVANTAGE - Reduces the penetration of flux into the connector and improves the quality of the connector contacts and the yield of the soldering process. The process is used in PCB mfr.
