Title: Improvements in cutting mechanism for cigarette making machines
IPC: A24C5/28
Filed: 1930-04-14
Abstract: 353,492. Grinding-machine cutters in situ. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) April 14, 1930, No. 11747. [Class 60.] In a cutting mechanism an orbitally moving frame supports both a rotary cutting blade and a co-operating ledger plate and by its movement it periodically brings the ledger plate into a supporting position for the cigarette rod, the cutting blade being rotated m such relation to the orbital movement of the frame that it cuts across the rod at the same time as it is supported by the ledger plate.

Patent GB-669486-A (GB)
Title: Self-quench superregenerative amplifier
IPC: H03D11/02
Filed: 1949-05-03
Abstract: 669,486. Super - regenerative circuits. HAZELTINE CORPORATION. May 3,1949 [May 22, 1948], No. 11806/49. Class 40 (v). A super-regenerative amplifier has a selfquench system comprising an auxiliary resonant circuit, which is caused to oscillate to control the main oscillation build-up but which is damped by the amplifier valve during the saturation period to quench the auxiliary oscillations. As shown, the amplifier comprises an oscillatory circuit 14, 15, 16 into which the signals received by an aerial 35 are induced and connected to a valve to form a Colpitts oscillator. Quenching is effected by an auxiliary resonant circuit comprising an inductor 22 connected by a R.F. choke 23 to the anode, and a capacitor 19. During the saturation period which lasts for about 10-15 per cent of the quench cycle the capacitor discharges rapidly through the valve and the anode current falls to a low value (as shown at t1 in Fig. 2a) at which the signal frequency oscillations are quenched. The capacitor then recharges in an oscillatory manner through the inductor 22, the anode voltage rising to a value of nearly twice the supply voltage producing a rapid oscillation build-up in the main tuned circuits and thus permitting a high quench frequency to be used. The self-quench frequency may be varied by adjusting the variable resistors 36 and 26 causing the position of the commencement of the saturation period to vary, three possible positions being shown at t<SP>1</SP>3, t3 and t<SP>11</SP>3. A long time constant circuit 26, 27 (as described in Specification 646,331) is provided for stabilizing the mean grid current and thus the mean quench frequency and if the commencement of the saturation period is arranged to occur at t3 this circuit is particularly effective since, for example, an increase of signal strength moves the commencing point to the left, increasing the anode voltage and thus increasing the saturation period. This tends to produce a greater increase in mean grid current than would otherwise occur and so increases the control exercised. The auxiliary resonant circuit may alternatively be connected in the cathode or grid leads, Fig. 4 (not shown), and may have a resonant frequency between one-tenth and ten times the quench frequency, typical quench waveforms being shown at P, Q and R (Fig. 2a). In order to ensure that the quenching cycle starts under all conditions of switching on, a resistor 24 is connected in series with the anode lead, the time constant of this resistor and capacitor 19 being about one-fifth of the period of a quench cycle. This circuit may be supplemented by an R.C. network connected in the grid or cathode circuits having a time constant approximately equal to the saturation period (Fig. 3, not shown). Specification 657,239 also is referred to.
