Patent DE-3928739-A1 (DE)
Inventor: BLACKBURN GODFREY ROLF
IPC: B61C9/52
Filed: 1989-08-30
Abstract: A single reduction spiral bevel gearbox for a high speed electric railway locomotive needs effective lubrication at both high and low speeds. The gearbox includes a casing (10), an input shaft (15) journalled in the casing and carrying a spiral bevel pinion (19), and an output shaft (16) journalled in the casing and carrying a spiral bevel wheel (26) in mesh with the pinion. A first lubrication system for low speeds comprises an apertured machined shroud (44) fitting closely around the lower periphery of the bevel wheel which flings oil from the shroud into troughs (50) whence it is ducted to the bearings of the shafts. A second lubrication system for high speeds comprises twin vane-pumps on a common shaft driven by the output shaft, which pumps supply oil through parallel duplicated hydraulic circuits to the bearings of the input and output shafts and to nozzles (73) for spraying the pinion teeth. Both systems remain operational at all speeds. <IMAGE>

Title: Adjusting angular position of seat backrest - involves bush with steep angle screw thread operated by vehicle driver
Inventor: WERNER HEINZ
IPC: B60N2/22
Filed: 1990-02-03
Abstract: The seat of a motor vehicle has a backrest which can be adjusted for angular position. The base of the seat has two side plates (10) with attached bosses (15). Each boss (15) has an external screw thread with a stepp leading angle and can be a multi-start thread. Each boss (15) engages a screw thread in a bush (28) which is welded to a plate (11) fastened to one side of the back rest. A hadnwheel (20) is mounted on a shaft (16) which can rotate in the boss (15) but is prevented from axially. The shaft (16) has a self-locking screw thread (23) which engages a screw thread in a plate (26) fixed to the bush (28). As the handwheel (20) is rotated the shaft (16) is screwed further into the plate (26) driving the boss (15) into the bush (28) and so causing relative rotation between boss (15) and bush (28). At the same time the shaft (13) produces the same effect on the other side of the backrest. The backrest is thus swung through an angle relative to the seat base. USE - Motor vehicle seat with adjustment system.

Title: Tensioner device for chain or belt drives - uses engine oil pressure to reduce mechanical tension spring force
Inventor: FEUCHT HANS JUERGEN DIPL ING
IPC: F02B67/06
Filed: 1991-01-10

Title: Evaporator for anaesthetic - has interlocked filler and out-flow valves so that when one valve is open other is closed
Inventor: FALB WOLFGANG
IPC: A61M16/18
Filed: 1991-03-15
Abstract: An apparatus for evaporating an anaesthetic consists of an evaporator vessel which is equipped with a filler device (4) and a flow control device, which is actuated by a handwheel (3). The filler device (4) is equipped with a valve which can be opened by rotating the cam (6) which pushes the locking rod (8) upwards. The locking rod (8) engages a recess (9) in the handwheel (3) and so prevents it from being operated whilst the evaporator is being filled. In order to permit the flow of anaesthetic out of the evaporator the cam (6) must be rotated to the closed position of the filler valve before locking rod (8) can be disengaged from the handwheel (3) to allow the outflow valve to be opened. USE/ADVANTAGE - Evaporator for anaesthetic. The filler valve can only be opened when the outflow valve is closed and vice-versa.

Title: Load controller for quantity controlled IC engine - has electronic slip-monitor to operate extra set of valves in induction manifold
Inventor: MEIER KURT
IPC: F02D9/02
Filed: 1991-03-22
Abstract: The throttle valve (6) in the intake circuit to the multi-cylinder engine is supplemented by a set of slide valves (10,11), either linear or rotating, one per cylinder.
