Patent DE-4319495-A1 (DE)
Title: Hydraulic steering servo, for vehicle, with variable reaction force - has flow control by=pass channel to regulate flow-rate and control reaction force to steering.
Inventor: HAGE KYOSUKE
IPC: B62D6/02
Filed: 1993-06-11
Abstract: The servo steering system has a servo pump (10) linked to a servo unit (3) via a flow restriction (12) and a control valve in the steering unit. The flow restriction is bridged by a bypass channel (51) with a flow control valve (15) and a spring loaded pressure control valve (2) and a sump (18). The sump is fed via a solenoid valve with the valve opening related to the vehicle speed etc.. This controls the fluid pressure w.r.t. vehicle speed and hence the steering reaction. The fluid is ducted to the sump when the steering force is low and is blocked for higher pressures. ADVANTAGE - Simplified servo action, less fluid waste, improved steering reaction.

Title: Rotor unit for axial flow turbo-engine - with constant profile variation of fluid passage between rotor core and outer jacket
Inventor: ARTINANO ANTONIO
IPC: F04D29/18
Filed: 1993-06-18
Abstract: The rotor unit has an inner rotor (12'), extending across a set axial length, and consisting of a rotor core (13) with blades (14). The inner rotor acts with an external jacket (16), the axial length of which is at least the same as that of the inner rotor. The rotor core and the external jacket together form a passage profile for a flow. The flow varies continuously from intake end (22) to discharge end (16). Constant axial acceleration of the fluid, and formation of corresponding pressure gradients take place in the flow. The blades, which are connected to the core in the area of fluid passage, have a constantly varying angle of incidence to produce a constant angular acceleration of the fluid. USE/ADVANTAGE - Rotor unit for axial flow turbo-engine guarantees constant function of pressure and fluid course under varying conditions.

Title: Commercial freight vehicle tailgate platform hoist
Inventor: WILD ROLF
IPC: B60P1/44
Filed: 1994-08-30
Abstract: The tailgate is lifted and lowered using servo-powered arms (14) with the servo control via a conventional control panel (18) on the side of the truck. Foot operated buttons (24) on one side of the tailgate platform raise and lower the system. For safety the foot operated controls have priority over the hand operated controls. Both controls are linked by a processor (16). The priority of the foot controls extends over the next operation e.g. if the tailgate is raised via the foot controls the priority for the foot controls remains until the tailgate is fully lowered again. In the event of a cable break for the foot controls a failsafe control switches control to the hand controls. Acoustic signals provide a clear indication that particular controls have been correctly operated.

Patent DE-4445177-A1 (DE)
Inventor: KIRSTEN MARIO DIPL ING
IPC: C23C16/52
Filed: 1994-12-17
Abstract: The invention concerns a process for preparing micromechanical components having free-standing microstructures or membranes which are under a predetermined mechanical stress. According to the process a sacrificial layer is first applied to a substrate, a polysilicon layer is applied to the sacrificial layer by vapour phase deposition, and finally at least part of the sacrificial layer is removed again. The process is distinguished in that the type of layer stress on the polysilicon layer depends on the processing pressure selected during deposition, the amount of layer stress being adjusted by the process temperature selected. The process pressure in each case is above the pressure range set for low pressure chemical vapour deposition reactors. In this way free-standing structures can in particular be produced such that they can be reproduced with specific tensile stress.
