Patent DE-3824918-A1 (DE)
Title: Fluid reservoir with at least one partition wall, especially for brake systems with brake reservoir warning device
Inventor: GOEHRING FRANK
IPC: B60T17/22
Filed: 1988-07-22
Abstract: The invention relates to a brake fluid reservoir and has the object of simply reducing the variation of the fluid level due to lateral forces. The said forces may result due to centrifugal forces when braking or from an inclination of the reservoir. The invention is in principle achieved by the provision of one or more partition walls, partially allowing the fluid to pass in a vertical direction through suitable openings, which partition walls are inserted into the reservoir essentially in a horizontal direction. The openings may also be distributed over the partition walls, for example by using a porous sintered metal as material. The invention is especially suitable for brake fluid reservoirs provided with warning devices, so that these cannot be triggered inopportunely. The invention affords particular advantages in brake systems with slip control, in which the warning device is automatically switched off in response to a supposed loss of brake fluid. <IMAGE>

Title: Clamping device for a ski
Inventor: LEITINGER WALTER
IPC: A63C11/14
Filed: 1988-11-17
Abstract: The conventional clamping devices for skis are constructed on the principle of the vice, with a fixed clamping part and a movable clamping part. The latter is set by means of a screw rod in accordance with the width or thickness of the ski and then tightened. Such devices are not suitable, for example, for clamping snow-sport equipment with oblique lateral cheeks or relatively large width. The new clamping device is intended, inter alia, for universal use in these cases also. The adjustable clamping part is mounted to be pivotable about a vertical axis and is so shaped that the distance D between its clamping surface and corresponding clamping surface of the stationary clamping part decreases constantly during the pivot movement. Furthermore, the adjustable clamping part or both clamping parts may bear suction cups. The clamping device permits rapid and reliable clamping of snow-sport equipment of all types for service and repair purposes.

Title: Actuator for a throttle butterfly of an internal combustion engine
Inventor: BAUR ULRICH DR
IPC: F02D11/10
Filed: 1989-02-25
Abstract: The invention relates to an actuator for a throttle butterfly (5) of an internal combustion engine, particularly for adjusting the throttle butterfly over part of its range of adjustment, in which a throttle-butterfly shaft (2) pivotably mounted in a throttle body (1) is connected to the throttle butterfly. The proposal according to the invention is that the actuator should have, running around the throttle body, a return (6) composed of magnetic material, which is provided with one or more excitation windings (7), and that a permanent magnet (11) or a magnetic short-circuit should be attached to or integrated into the throttle butterfly, the said short circuit having poles (N, S) associated with the return. The actuator is distinguished by its particularly simple constructional configuration, operates with little wear and takes up only a little space. Due to the optimum efficiency of the actuator in the region of small deflection angles of the throttle butterfly, the adjusting device according to the invention is particularly suitable for controlling the idle-speed range of the internal combustion engine. A further development of the invention envisages that the part-load and full-load range of the internal combustion engine should be controlled by means of a separate actuator, for example by means of a Bowden cable. <IMAGE>

Filed: 1990-01-15
Abstract: A harvester comprises a ground-tracking cutting mechanism which is fastened to a height-adjustable conveyor shaft to be pendulating. The reaching of limits of the range of pendulation is signalled by an initiator assembly which comprises two initiators (20S, 20H) and is associated with a shaft height initiator (26). The shaft height initiator checks the shaft movement and activates the two initiators (20S, 20H) of the initiator assembly by means of a logic circuit (27). The logic circuit (27) is followed by a two-channel switching amplifier (28) and two electromagnetic valves (33, 34) for raising and lowering of the conveyor shaft. The outputs of the initiators (20S, 20H, 26), manual control keys (29, 30) connected with the inputs of the switching amplifier (28), and a switch (31) blocking the signals of the initiators (20S, 20H) of the initiator assembly, are connected to the inputs of the logic circuit (27). After switching-on of the height control system and lowering of the conveyor shaft through brief actuation of one of the keys (30), the movement of the shaft is controlled by the signals of the two initiators (20S, 20H) only after they have been activated by the shaft height initiator (26) in the working range. <IMAGE>

Inventor: FARACE LOUIS PASQUAL
IPC: G01P15/125
Filed: 1990-05-14
Abstract: A double integrating silicon acceleration sensor which is solid state and micromachined measures the acceleration of an object and determines the distance travelled by that object through its trajectory. The sensor comprises a hermetically sealed container. The cavity within the container is divided by a flexible silicon diaphragm 12 into two separate cavities, one shallow 24 and the other deep 26. The two cavities are filled with a fluid which is relatively incompressible over the range of operating pressure. The fluid can only transfer between the two cavities through an orifice 18. Two capacitor plates form a capacitor within the shallow cavity. One of the plates 16 is secured adjacent to and opposite of the first plate 14 within the shallow cavity. Further capacitor plates 42, 44 within the deep cavity may also be provided. The flexible diaphragm has semi-spherical dimples, in a hexagonal close pack pattern in at least one face. When the accelerometer experiences an acceleration, the diaphragm deflects into the deep cavity forcing fluid from the deep cavity into the shallow cavity. The gap between the two capacitor plates increases causing a change in the total capacitance. This capacitance value is exactly proportional to the distance travelled by the object for constant acceleration, and is approximately proportional to the distance travelled for other acceleration pulses. When capacitor plates are also located in the deep cavity, a differential capacitance results. <IMAGE>
