Title: Seal for shaft passing through housing wall - has back=up bellows operating when main bellows fails
Inventor: KATZENSTEINER JOSEF ROMAN
IPC: F16J15/3256
Filed: 1991-06-05
Abstract: The first main flexible but rotationally secured bellows (14) are mounted between the wall (2) and shaft (1). The second backup bellows (15) connects the outer edge (17) to the inner edge (20) of the first bellows (14). In order to avoid inflation of the hollow cavity and thus to increase the service life at least a cavity (23) between the two bellows (14,15) contains a viscous fluid with low heat expansion. This fluid only boils above a maximum operating temperature and only solidifies below a lowest operating temp. USE/ADVANTAGE - Sealing system for shaft with backup bellows. The second bellows remains completely sealed for a certain time.

Title: Surface acoustic wave resonator mfr. for precise resonator  frequency - involves forming identical reflector structures, and short-circuiting selected structures to control centre frequency
Inventor: FLEISCHMANN BERND

Firstly, identical reflector structures are mfd. and then at least one reflector structure is short circuited for the reduction of the centre frequency. For increasing the centre frequency, a short circuit in at least one reflector structure is removed. Pref. the short circuit, or its removal, is carried out in reflector structures outside the interdigital converters in the resonator. Alternatively, the short circuit steps may be carried out in reflector structures within the resonator interdigital converters. ADVANTAGE - Simple technical process for very small tolerances.

Title: ABS system for motorbikes - has master cylinder connected to wheel cylinder via three valves, hydraulic pump and high/low pressure reservoir
Inventor: STEMMER FRANK
IPC: B60T8/42
Filed: 1992-06-04
Abstract: An ABS system, especially for motorbikes, has a hydraulic engine-driven pump to generate brake fluid pressure, several valves and a high/flow pressure reservoir with pistons at either end. The reservoir is connected to the wheel cylinder and in parallel with the pump. The pistons of the two reservoir chambers can move with respect to each other, the movement being detected by an inductive displacement sensor. The output from this sensor then determines the setting of the three valves, one connecting the wheel cylinder to the master cylinder and two in the reservoir-pump circuit. The first of these valves is closed during the ABS regime. A second example uses a fourth valve for the pressure build-up process. ADVANTAGE - Smooth regulation of braking.

Patent DE-4226548-A1 (DE)
Inventor: WENDEL FRIEDRICH
IPC: H02K37/16
Filed: 1992-08-11
Abstract: In a prior art actuator the stator is either made in two parts or the exciting winding must be fitted directly on the stator, involving a laborious production process. The novel actuator is intended to provide simple and economical production with good setting properties. The sheet metal laminations (6) forming the stator (3) of the actuator (1) have weakened points in the region of the poles formed by either cut-outs (41) or cuts (42). An induction core (4) with a winding (5) is inserted into a yoke formed on the stator (3) so that a magnetic field can be induced in the stator (3). The alternating combination of sheet metal laminations having cuts (42) and cut-outs (41) makes it possible to optimise the torque/angle of rotation characteristic of the actuator (1) in favourable manufacturing conditions. The actuator for adjusting the angle of rotation of a setting device is used, for example, to control the opening cross-section of a line conveying a medium in internal combustion engines for idling speed control.
