Title: Apparatus for cutting longitudinally extending workpieces
IPC: B23D57/00
Filed: 1975-03-05
Abstract: 1488190 Sawing GEORG FISCHER AG 5 March 1975 [7 March 1974] 9228/75 Heading B5L [Also in Division B3] Apparatus for cutting pipes &c. of various diameters comprises a stationary chuck 2 for holding the workpiece, a coaxial housing 1 which supports a motor driven cutting tool, e.g. saw 7, for radial adjustment by means of cooperating eccentric rings 3, 6 and for orbital travel about the workpiece to be cut. With a pipe 9 clamped in the chuck 2 and projecting through the housing 1 the cutting tool support ring 6 together with saw 7 and motor 8 is rotated from a rest position in contact with a fixed stop 13 on bearing ring 3 until a drive pin 12 on the ring 6 comes into contact with an adjustably set stop 11 on bearing ring 3, this initial movement bringing the tool to its required radial position; thereafter the rings 3 and 6 rotate together about the central axis of the apparatus to cause the cutting tool 7 to move in a cutting path orbitally around the pipe 9. Reverse movement brings the ring 3 to its basic position in which a spring loaded slide and roller detent mechanism 10, Fig. 5, retains the ring relative to the housing 1 while the cutting tool support ring 6 can then be brought to its rest position against stop 13. A marked scale 41 is provided for the adjustable stop 11, the markings corresponding to pipe diameters of pipes to be cut.

Abstract: 609,970. Frequency modulation. PHILIPS LAMPS, Ltd. March 27, 1946, No. 9419. Convention date, Sept. 17, 1941. [Class 40 (v)] Linear control of a valve reactance is effected by rectifying the oscillatory current flowing through the valve and feeding back the rectifier voltage to the valve grid in phase opposition to the modulating voltage. In the F.M. transmitter, Fig. 1, a valve generator 1 has its tuned circuit connected across the reactance valve 2, the grid of which is excited by a quadrature voltage derived from the normal phasing network. The modulating source 9 is connected between grid and cathode of the valve 2. A small coil 3 in the anode circuit is coupled to a tuned circuit 5 feeding a rectifier 7, the load resistance of which is in series with the source 9 to give a negative feed-back and to ensure linearity of modulation. Current flowing in the coil 3 due to the anode-earth capacity of the valve 2 is balanced in its effect on the circuit 5 by an oppositely-coupled coil 4 in series with an equal capacity 6. In a modified circuit, Fig. 2, the quadrature voltage from the phasing network is applied to the grid of the valve 2, is amplified therein, and is transferred through condenser 11 to the grid of a reactance valve 12 which has its anode and cathode connected across the oscillator tuned circuit. Negative feed-back is provided from the valve 2 as in Fig. 1. The modulating voltage may be applied in parallel to the grids of both valves 2, 12.
