    摘要： 972,566. Removing metal by fusion. TELDIX LUFTFAHRT-AUSRUSTUNGS G.m.b.H. Dec. 14, 1962 [Dec. 14, 1961], No. 47291/62. Heading B3V. [Also in Divisions G1, H1 and H3] A process for dynamically balancing a rotating or oscillating body 1 such as a gyroscope, crank-shaft or pendulum, comprises determining the size and position of the imbalance whilst the body is being rotated or oscillated, and eroding away the imbalance material by means of a focused beam 8 until the imbalance reaches the desired approximation to zero. The beam may be an electron beam produced by a source 9a and focused by a system 9b. A control device 6 which receives imbalance signals from the bearings 2, 2 1 controls a pulse generator 7 which determines the pulsing and intensity of the beam, and also a beam-deflecting system 9. Alternatively, the point of impingement 11 of the beam may be fixed and the bed 3 moved axially. In another embodiment, Fig. 3, the rotating body 1 is eroded by a light beam 42 emitted from a laser crystal 40 focused by a lens 41. A computing and control device 6a which receives signals from vibration sensers 27, 27 1 controls through switch 35 the supply of energy from source 7a to a lamp 36 used for optical pumping. At optional time intervals short light flashes are produced by lamp 39 controlled through switch 38 to provoke a strong laser beam. The lamp 39 may be omitted and the lamp 36 used with longer pulses to produce the laser beam. Axial movement of the body 1 on runners 29 or optical deflection of the laser beam is also controlled by device 6a. Two separate beams may be used to produce erosion in two balancing planes. Control systems are described for both the electron beam, Fig. 2 (not shown), and the laser beam apparatus, Fig. 6 (not shown).
