Title: Interference method for measuring phase shift of light waves
Inventor: TELESHEVSKIJ VLADIMIR I
IPC: G01B21/00
Filed: 1991-06-28
Granted: 1994-11-30
Abstract: FIELD: measurement technology. SUBSTANCE: method involves division of radiation of laser 1 incident onto acoustooptic modulator 2 by reference and measuring fluxes of different optical frequencies. Measuring flux is passed to measuring channel of interferometer 4. Reflected radiation is spatially aligned with reference flux radiation and sent to photodetector 6 whose output signal goes to input of measuring circuit and then to acoustooptical modulator 2. The reversal of polarity of measuring circuit conversion factor at extreme phase shift of light waves provides for elimination of time-limited discrete frequency processes in acoustooptic modulator 2 (frequency hopping) and to shape instead of them low-duration logical information pulses. Changing absolute value of measuring circuit conversion factor enables shaping of pulse-to-pulse spatial period of desired value. EFFECT: improved speed of response due to improved processing speed of measuring data; enlarged functional capabilities of laser heterodyne method of displacement measurements. 2 cl, 4 dwg

Abstract: FIELD: mechanical engineering; friction units. SUBSTANCE: antifriction bearing has outer and inner races, balls and seals preventing leaking out of lubricant. Anodes secured on inner wall of seals are dielectrically insulated from bearing body and are made of metal or alloy containing required additions. Used as lubricant is current conducting ion-forming liquid.

Friction of bearing parts leading to their wear is activating action contributing to electrochemical settling of material of anode onto surfaces of bearing liable to wear. Required service life of bearing and friction coefficient can be provided by changing the content of ion-forming liquid, geometrical shape and dimensions of anode and its composition.

Filed: 1995-02-17
Granted: 1996-07-25
Abstract: The valve has a body with a bore (11), and connections (B,P,T) for the fluid which is to be controlled by a sliding element (20) inside the body. The element has at least two throttles (21), each having a throttle surface (22) formed by an external curved surface which tapers from one end. The bore has sleeves (30) with internal curved surfaces in order to act as seats for the throttles. In a partly open state, a channel is formed between each throttle surface and its corresponding seat surface, whose flow cross-section depends on the position of the slide. The cross-section increases as the slide moves towards the open position, and reduces as the slide moves towards the closed position. Each sleeve has a stop which is acted upon by a spring in order to force the sleeve against the slide.
