Title: Method of magnetoelectric alloying metal surfaces
Inventor: SHULEV GENNADIJ S
IPC: B23H9/00
Filed: 1991-05-06
Granted: 1994-07-30
Abstract: FIELD: improving wear resistance of metals. SUBSTANCE: a mixture of ferropowder and nitrogen is conveyed to alloying zone. Prior to entering the alloying zone the mixture is passed through alternating magnetic field and electric discharge zone. The action of alternating magnetic field ensures activation of the surface of powder and saturation with nitrogen. Nitrogen is disintegrated into atoms under the action of electric discharge. As a result, only atomic nitrogen and saturated activated powder are conveyed to the alloying zone whereby the workpiece surface is activated with atomic nitrogen. The process of alloying proceeds when the workpiece surface is exposed to electric discharges and magnetic field accompanied by vigorous chemical reactions thanks to activation of powder and workpiece. EFFECT: enhanced efficiency of the method. 1 dwg

Granted: 1995-08-20
Abstract: FIELD: radiolocation. SUBSTANCE: high-frequency pulse sequences are formed with carrier frequency F 0  and then radiated into the air at the region of guard area; moving object is irradiated by the signals when entering guard area. Low-frequency pulse sequence signals are received with carrier frequency F 0  and high-frequency pulse sequences are received after being reflected from moving objects; the latters have Doppler frequency addition to carrier frequency F 0 +F D . Signals after being received, are transformed by means of mixing, and useful signal is selected from mixture spectrum. Then high-frequency pulse envelop signal is formed, and videopulse signal in sequence is amplified. Videopulse envelope signal is formed after that. Then signals with difference Doppler frequency F D  are formed and frequency selected according to specific transmission frequency. Doppler frequency useful signal is determined from object moving at the guard area, from the changes in signal value sign. After videopulse signal sequence is formed and preamplified, the videopulses are attenuated in sequence (automatic or manual) under control, till useful pulse difference Doppler frequency videosignal is formed after being frequency selected. EFFECT: improved reliability; improved precision. 4 cl, 5 dwg
