IPC: H05B6/02
Filed: 1948-09-06
Abstract: 642,292. Induction heating. STIVIN, J. Sept. 6, 1948, No. 23401. Convention date, Sept. 5, 1947. [Class 39(iii)] In order to obtain concentrated heating at a point or small area 16 of the surface of a workpiece 11, the secondary 14 of the transformer 15 is connected to a straight conductor 13 forming the heating conductor. Relative rotation is provided between the heating conductor 13 and workpiece 11 about an axis 17 causing all points of the surface of the workpiece to traverse underneath the heating conductor except the point 16 which remains beneath it throughout the rotation and is thereby heated to a higher temperature than the remainder. In addition to the relative rotation a linear component of travel may be given to either the heating conductor or workpiece in order to weld or cut along a line 12. In a further example, Fig. 14, die plates 81 are rotated between a wheel 82 and an arcuate surface 83, the heating conductor 84 being arranged to follow the path of the centre of the die plates, thereby effecting a concentrated heating of the central or cutting portions of the die plates without hardening the remainder.

Title: Signal processing circuitry
IPC: G01S3/80
Filed: 1973-05-18
Abstract: 1433244 Wave-energy position finding FRANCE ARMED FORCES MINISTER OF 18 May 1973 [18 May 1972] 23930/73 Heading H4D In a wave-energy system (o.g. a sonar or radar system) noise and interference reduction is accomplished by feeding the input signal via a narrow band filter to a first threshold device 30 which converts the filter output into logic "1" signals when that threshold is exceeded, the logic "1" signals are converted to continuous pulses, and the continuous pulses gate clock pulses which are integrated and then passed to a second threshold device 43 which issues an output signal when the second threshold is exceeded. In one embodiment the first threshold level is made partly dependent on the integrated output of half-wave rectifier 15 and partly dependent on an adjustable D.C. 23. The gating pulses are produced by a circuit 60 which comprises monostable trigger circuits and an OR gate, Fig. 5a (not shown), and its output feeds a processor 40 incorporating a clocked store 41, an integrator 42 and a circuit 43 which issues a signal if its (adjustable) threshold is exceeded by the output of integrator 42. Automatic gain control amplifier 13 reduces input signal variations to 40 dB from 80 dB. The invention may be applied to pulsed-FM sonar, and reduction of Doppler effect is achieved in a further embodiment by relating the clock frequency to the received echo.
