Title: Hydraulically actuated braking device, particularly for spot-type disc brakes
Inventor: WEIDENWEBER MICHAEL
IPC: F16D65/84
Filed: 1989-01-31
Abstract: The invention proposes a hydraulically actuated braking device, particularly for spot-type disc brakes, with a piston (10) which is arranged in a housing bore (2) and the piston end of which that points in the actuating direction and projects from the housing bore (2) engages on a friction lining (1) interacting with a brake disc (12), with a heat shield (3) that can be mounted at the end of the piston on the circumferential surface of the piston, and with a flexible folding sleeve (9) which is secured behind the heat shield (3), the first end section (13) of which is secured on the circumference of the piston (10) and the second end section (14) of which is likewise secured with a cylindrical part, the face (2) of the heat shield (3) facing away from the brake lining (1) having properties associated with low thermal conductivity and/or heat radiation and the face (4) of the heat shield (3) facing the brake lining (1) having properties associated with good heat radiation. Heat shields hitherto used have the disadvantage that, when the material is heated up, radiated heat is released on all sides and, as a result, particularly in the case of inadequate air ventilation of the brake, the heat radiation leads to premature damage to the adjoining temperature-sensitive folding sleeve. The heat shield arranged and designed in accordance with the invention lowers the thermal stress and thus increases the functional reliability of the folding sleeve. <IMAGE>
Patent DE-3907320-A1 (DE)
Inventor: YAMAMOTO HIROHARU
IPC: G01S15/89
Filed: 1989-03-07
Abstract: In an ultrasonic diagnostic apparatus for effecting sector scanning by reciprocating an ultrasonic vibrator in a toward direction and a reverse direction via a transmission mechanism and for providing an ultrasonic picture image in synchronism with an output signal from an encoder for detecting the position of the ultrasonic vibrator, distortion is caused by a positional shift of the ultrasonic virator due to backlash of the transmission mechanism in moving the ultrasonic vibrator in the forward and reverse directions. The method comprises the steps of generating an ultrasonic scan signal during the movement of the ultrasonic vibrator in the forward and reverse directions, adding a backlash correction signal to the ultrasonic scan signal to produce a picture signal corresponding to the ultrasonic plcture image, and adjusting the magnitude of the backlash correction signal such that the picture signal is compensated for the amount of backlash of the transmission mechanism. <IMAGE>
Patent DE-3920169-A1 (DE)
Inventor: FILBERT DIETER PROF DR ING
IPC: G01M11/00
Filed: 1989-06-16
Abstract: A light pulse is applied to a light-waveguide (10) for the purposes of examining the latter; signals back-scattered owing to its damping profile (Rayleigh reflection) and from interference points (12) (Fresnel reflection) are taken via an optical divider (18) to an optical receiver (22), the electric output signal of which is amplified and transmitted via a low-pass filter to the rest of the signal processing system. Owing to the wide dynamic range of the back-scattered signals and to the fact that the signal back-scattered through Rayleigh reflection lies below the natural noise of the optical receiver (22), contradictory requirements are made of the limit frequency of the low-pass filter, which can thus constitute only an unsatisfactory compromise. The device of the invention comprises a signal-tuned filter (26) preferably consisting of a surface-wave convolver (26); it thus has a considerably better signal to noise ratio and an imaging error on the occurence of Fresnel reflections which is precisely limited in time. Application: investigation of light-waveguides.

Filed: 1989-09-25
Abstract: A liquid counter in the form of a hydrometric vane or turbine flowmeter comprises two interconnected measurement wheels (55, 56) installed in tandem in the direction of flow. Control paddles (73, 74) arranged on both sides of the wheels influence the flow to, and away from the measurement wheels (55, 56). The control paddles are controlled, via a gearing, by means of a closure plate (31) arranged centrally on a bearing body for the measurement wheels (55, 56) and guided in the bearing body. The entire liquid counter (10) is therefore symmetrical about a plane of symmetry perpendicular to the direction of flow, and therefore both incorporation of the measurement wheels and adjustment of the liquid counter are simplified. In addition, no seals are required.
