Title: Improvements in or relating to conveyers
IPC: B65G47/29
Filed: 1952-06-12
Abstract: 744,359. Conveyers. LONDON BRICK CO., Ltd., and HERSEE, E. D. June 12, 1953 [June 12, 1952], No. 14857/52. Class 78 (1). The angular relationship of an article to a conveyer on which it travels is changed by transferring it from a first conveyer to a second conveyer at the desired angle relative to the first by means causing the article to be propelled forwards and upwards so as to leave the first conveyer and jump on to the second. As shown, bricks 2 from a number of forming presses (not shown) pass in lines on conveyers 3 to a collecting conveyer 1 over which each conveyer 3 projects a different amount to deposit the bricks in spaced rows. Conveyer 1, e.g. a roller conveyer, feeds the bricks to a section 4 provided with conical rollers 5 and guide 6 for transferring the bricks to a transverse conveyer 10. The spindles 5a, Fig. 4, of the rollers 5 project inwardly and are equipped with rollers 7 frictionally engaging a driving wheel 8. Conveyer 10, e.g. an endless belt 12, is provided with guides 11 for directing the articles in rows where they accumulate in contacting relationship against a stop 16, Fig. 3, positioned between three idling rollers 14 and a driven roller 15 on one side, and two rollers 17 driven at high speed on the other side. Upon release of stop 16 through cam means (not shown) the first brick in each row is caused to accelerate quickly by the rollers 17 so that it jumps to delivery conveyer 18 while the stop is returned by the cam means to stop the next row of bricks until the first row have been moved by conveyer 18 through gaps 19 in the guides 11.

Patent GB-483890-A (GB)
Title: Improvements in or relating to circuits for multiplying or dividing the frequency of high frequency and ultra-high frequency oscillations
IPC: H03B19/08
Filed: 1937-06-02
Abstract: 483,890. Valve circuits ; magnetrons. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 2, 1937, No. 15361. Convention date, June 5, 1936. [Classes 39 (i) and 40 (v)] For multiplying or dividing high or ultrahigh frequencies, the cylindrical anode of a magnetron is split into various numbers of equal or unequal segments, which are divided into two groups. These two groups are connected through a circuit 9 tuned to the fundamental. In the frequency-doubling arrangement shown in Fig. 1, the groups are respectively above and below the diametral plane AB, while the pairs 2, 4 and 6, 8 of electrodes are connected through circuits 5, 7 tuned to the second harmonic. When oscillations of the fundamental frequency are applied to or generated in the circuit 9, oscillations of the first harmonic frequency are produced in the circuits 5, 7. For frequency-halving, the basic oscillations are supplied to the circuit 5, 7 and the divided frequency is taken from the circuit 9. In a modification, Fig. 2 (not shown), the circuit 7 is suppressed and the electrodes 6, 8 are united to form a halfcylinder, in order that oscillations of the higher frequency may not be spontaneously generated by the tube. For multiplying the frequency by 3 the electrodes 2, 4, 6, 8 are replaced by six electrodes suitably grouped, Fig. 3 (not shown), or, as shown in Fig. 4, there may be one semi-cylindrical electrode 24 and three smaller electrodes 12, 14, 16, of which 12 and 16 are directly connected, the circuit 9 being tuned to the fundamental while the circuit 13 is tuned to the third harmonic. For multiplying the frequency by 4, Fig. 5 (not shown), the three electrodes 12, 14, 16 are replaced by four electrodes cross-connected in pairs. The electrode 24, Fig. 4, may be divided into two parts, and the second and third harmonics may be produced simultaneously from the fundamental by means of suitably tuned circuits, Fig. 6 (not shown), and similarly the second and fourth harmonics may be produced simultaneously, Fig. 7 (not shown). In the frequency-halving arrangement shown in Fig. 8, each of the two groups 62, 64 into which the electrodes are divided comprises alternate quadrantal electrodes joined through a circuit 33 or 35 which is tuned to half the natural frequency of the circuit 37 that connects the two groups. Oscillations supplied to or generated in the circuit 37 give rise to subharmonic oscillations in the circuits 33, 35. The third or fourth subharmonic can be obtained by the use of six or eight plates. For generating frequencies of the order of 4.10<8> c./sec. a lower frequency produced by a back-coupled oscillator may be stepped up by a frequency-multiplier constructed in accordance with the invention.
