Title: Device for clearing of drilling fluid
Inventor: MAL TSEV V A
IPC: E21B21/06
Filed: 1996-01-09
Granted: 1998-06-27
Abstract: FIELD: bore-hole drilling machinery and equipment. SUBSTANCE: this is intended for removing sludge from drilling fluid. Device is made in the form of body with charging and discharging holes, spiral-type auger, and driving motor. Spiral auger is made with toothed rim rigidly connected to auger. Body is connected by resilient link with supporting disk which interacts with toothed rim through supporting balls. Lower surface of toothed rim provides wavy trajectory for movement of supporting rollers which are secured on body. Upper surface of blade having triangle in its cross-section and pipe of spiral-type auger have tapered holes. At switching on driving motor, toothed rim and auger start rotating. Due to interaction of supporting rollers and wavy trajectory of rotating toothed rim, generated are vertical oscillations of auger which reduce cohesive forces between solid particles and clay drilling fluid, and this leads to more effective separation of sludge from drilling fluid. At rotation of auger due to inertial forces, sludge under effect of reduced cohesive force between it and clay drilling fluid is intensively moving towards inner wall of body and thus it is further moved upwards by spiral-type blades up to discharge hole. At same time, cleared drilling fluid passes through tapered holes in vertical pipe and blades for flowing down. Application of aforesaid device improves drilling fluid clearing efficiency and adds to increase of bore-hole drilling speed. EFFECT: higher efficiency. 4 dwg

Title: Current transducer
Inventor: SHAROMET O N
IPC: G01R19/22

Granted: 1999-09-27
Abstract: FIELD: measurement technology. SUBSTANCE: transducer has current divider built up of several parallel-connected conductors of which one carries wound core connected to inputs of measuring signal processing circuit, its outputs functioning as transducer data signal outputs. Transducer has at least two of above-mentioned parallel- connected conductors passed separately through holes of second magnetically soft core so that magnetic fluxes induced in mentioned second core by two portions of current being measured flowing in two respective conductors are opposing and compensating each other. Generator of linearly varying periodic current incorporated in transducer builds up linearly varying magnetic field in first magnetic core which is superposed on magnetic field excited by part of measured current and reverses its polarity from one saturation state to other and vice versa. Reversing polarity of first core induces voltage pulses in its winding; prior to do so, these pulses are passed through high-voltage filter and arrive at input of threshold device with hysteresis transfer characteristic; duration-to-space ratio of pulse train built up across output of the latter is just the information signal of transducer. EFFECT: improved design of transducer capable of measuring AC and DC current. 5 cl, 3 dwg
