Title: Passive joystick for aircraft
Inventor: NEUDOERFFER BERND
IPC: B64C13/04
Filed: 1997-05-09
Abstract: The joystick produces setback force by movement from a starting position by spring components, with damping of a backward movement of the joystick in a starting position. The damping devices (44) have a non-linear damping characteristic line. They provide relatively small damping for large movements of the joystick (10) and relatively large damping for small movements of the joystick. They have an symmetrical characteristic line in relation to the starting position. The damping devices contain a cylinder (46) with a damping medium, forming a throttle (56), in which a damping body (60) coupled with the joystick has a variable cross-section over its length, which with the throttle of the cylinder forms a stroke-dependent throttle cross-section. The throttle is formed by a cylinder ring (56) in the central area of the cylinder (46).

Patent DE-19732373-A1 (DE)
Title: Car door lock
Inventor: SAJFERT DRAGO
IPC: E05B83/36
Filed: 1997-07-28
Abstract: The lock is secured against triggering during assembly by an additional spring (8) which holds the release lever (2) at rest until automatically disconnected from the lever when the lever is first operated. The additional spring is more powerful than the lever spring (4) and is joined to the lever by a hooked spring end (9) which slidably engages the release-directed rear (10) of the lever from behind. The hook is guided along a slotted link (12) running along the lever movement, so that when the lever is swivelled once, one of the spring force components loading the spring stands normal to the rack (13) of the slotted link. At its end near to the release setting, the link has an undercut portion (14) so the spring hook engages this when first activated and in this way leaves the release lever under the load of the first spring (4) only.
Patent DE-19732661-A1 (DE)
Title: Control system for hydraulic suspension bearing in motor vehicles
Inventor: YOON YOUNG-WHAN
IPC: F16F13/14
Filed: 1997-07-29
Abstract: A control system for a hydraulic suspension bearing on a car has a unit to pass hydraulic pressure to the bearing (40) that is located on a chassis-sided contact part of a lower arm (4) of the suspension. A valve controls the pressure in the hydraulic chambers formed in the suspension bearing. An electronic control unit passes an electrical signal to this valve that depends on the travelling state of the car. The coefficient of elasticity of the bearing is adjusted corresponding to the magnitude and the frequency of the car's vibrations. The pressure in the hydraulic chambers is adjusted corresponding to the travelling state in order to take care of the desired steering stability and forward travel stability when an operating fault occurs in the car.

Title: Tire with internal flat-running support
Inventor: GLINZ MICHAEL
IPC: B60C17/06
Filed: 1997-10-15
Abstract: The support system (2) comprises three parts. An annular shell (3) is mounted on two annular ring supports (4, 5).

The frame and outer section (1, 2) are clipped together, cut to length and assembled as the frame. Not until glazing are they separated. Afterwards they are clipped together again.
Patent DE-19757258-A1 (DE)
Inventor: WIENAND KARLHEINZ DR
IPC: G01K7/18
Filed: 1997-12-23
Abstract: The invention relates to a temperature dependent multiplier resistor of a temperature sensor which is connected in series to a reference resistor, whereby a constant applied current passes through said series connection. A connection endpoint located between both resistors is connected to the N-input of a first countercoupled operational amplifier whose P-input is supplied with a direct voltage tapped by a voltage divider. When the temperature increases in the area of the multiplier resistor, the potential increases on the output of the first operational amplifier which is connected to the multiplier resistor. The operational amplifier supplies the applied constant current while the potential on the output of the operational amplifier decreases as the temperature falls. The temperature dependent voltage signal released on the operational amplifier is delivered to the P-input of a series connected second operational amplifier in a subtractor connection. The output of the second operational amplifier is connected to a measuring device for measuring the voltage which is characteristic of the temperature. In a preferred design, the multiplier resistor made of platinum or a platinum based alloy is directly deposited on a substrate made of ceramic (Al2O3) thus forming a thin-layer element. The reference resistor and the micromodule are additionally placed on the surface of the thin-layer element. The temperature sensor has a compact structure due to an evaluation circuit which is configured as a micromodule, and can be used up to temperatures of approximately 300 DEG C.

Abstract: A device for controlling a gas shuttle valve for internal combustion engines, comprising an axially displaceable valve member (5) with a sealing surface (7) that enables it to co-operate with a valve seat (8) fixed to the housing. The valve member has a piston (9) on the end that is far from the combustion chamber. Two hydraulic working areas are axially separated by the piston. A lower working area (11) close to the combustion chamber acts upon the valve member (5) in the direction of closing and an upper working area far from combustion chamber (15) acts upon it in the direction of opening. The lower working area (11) is permanently connected to a high pressure source and the upper working area can be alternately filled with high pressure and discharged by means of a high pressure feed line (23) containing an electric control valve (27) and a discharge line (33) containing an electric control valve (27). The electric control valve (35) closes the high pressure feed line (23) into the upper working area (15) at zero current, while the control valve (35) in the discharge line (33) is opened at zero current.
Patent DE-19826960-A1 (DE)
Inventor: WIEBE ULRICH
IPC: G02B6/25
Filed: 1998-06-17
Abstract: The present invention relates to a method for dividing a light guide (6) made of non-rigid, light-conducting material, wherein said light guide (6) is bent and cut with a blade (23) starting from its convex side towards the concave one. Since the light guide (6) is bent during the cutting process, the areas of the light guide (6) which are already partially cut are separated from the blade so that said blade cannot alter them anymore as it progresses through the light guide (6). It is thus possible to obtain substantially smooth cutting surfaces in light guides of this type.
