Title: Improvements in or relating to phase-synchronised electrical oscillators
IPC: H04N5/12
Filed: 1960-04-28
Abstract: 912,147. Keying carrier frequencies; transistor oscillator circuits. GENERAL ELECTRIC CO. Ltd., and PELLS, G. H. April 21, 1961 [April 28, 1960], No. 15044/60. Classes 40 (5) and 40 (6). Synchronizing square waves are applied through transistors 2, 5 to build up oscillations in a resonant circuit 6 tuned to the same frequency so that when a predetermined positive oscillation peak is reached it cuts off for an instant and produces from a transistor amplifier 13 a negative pulse switching over a bi-stable circuit 17 so that the transistor 2 and syncwave input are blocked and a previously blocked transistor 3 rendered conductive. Positive feed-back through the latter and amplifier 5 then generates oscillations in the tuned circuit 6 with a phase determined by that of the initial sync. wave input. The oscillation peak producing a switching pulse from transistor amplitude discriminator 13 is determined by the potentiometer 14, 15 and Zener diode 16. The bi-stable circuit 17 may be reset and the oscillations quenched by a negative pulse applied to lead 21 of duration at least equal to one oscillation period, this blocking transistor 3 and temporarily rendering conductive a normally blocked transistor 23 shunting the tuned circuit 6. The tuning capacitor 7 may be large compared with other capacities and the frequency generated 5 kc/s. The oscillator may be used in a receiver required to be phase locked with a transmitter transmitting a coded group of pulses, the messages being preceded by about 8 cycles of the square wave synchronizing signal.

Title: Improvements in or relating to a method of controlling the deflection of a charged particle beam and apparatus therefor
Inventor: BLUNDELL GORDON ROY
IPC: H05H7/00
Filed: 1965-04-13
Abstract: 1,084,582. Linear particle accelerators. MULLARD Ltd. Feb. 14, 1966 [April 13, 1965], No. 15682/65. Heading H1D. In apparatus, such as a linear accelerator, having a beam of charged particles, the pulse duration of the beam is controlled by deflection modulation with respect to an apertured shield 2, the deflection means being energized -by a pulse generator in which the onset of a shortduration pulse is derived from a clipped portion of a longer-duration pulse while the termination of the short-duration pulse is derived from the clipped off part of a delayed longer-duration pulse. As shown, deflection plate A is first biased so that when the beam is emitted by a source 1, it is deflected along path 5. The bias is then removed from plate A by means of a positive-going pulse allowing the beam to pass the aperture 3 on to a target after which plate B is pulsed deflecting the beam along path 5 or 6 and so terminating the beam pulse received by the target. As described, the source 1 is an electron gun, plate A is normally biased via diode 13 to -8 kV whilst B is earthed by diode 21. Shortly after the onset of a pulse of electrons from 1, thyristors or thyratrons 10, 12 are turned on by a pulse from 17 giving a + 16 kV pulse at the cathode of valve 10 which is clipped to earth by valve 12 so as to utilize the part of the pulse having the shortest rise time. This allows-the electron beam to traverse path 4 on to the target. After one or more nano seconds, thyratron 27 is turned on giving a negative-going pulse at the anode, the lower 8 kV passing diode 25 and turning off diode 21 so as to provide at B a pulse which deflects the beam to path 6 so terminating the pulse on the target. The use of the lower part of a clipped pulse at plate A and the upper part of a delayed clipped pulse at B makes the rise and fall times of the pulse on the target extremely short, the duration being dependent on the delay between pulse generators 17, 18 which is controllable by a low level circuit. The H.T. line 19 is pulsed at + 18 kV, a delayed pulsed supply being fed to the screens if tetrode thyratrons are used at 10, 12, 27. Diode 21 may be replaced by a thyratron triggered from 17. A single deflection plate may be employed if a circuit comprising valves 25, 27 is connected to plate A. The beam 4 and target (not shown) may form a high power switch.

Title: Improvements in or relating to work-feeding mechanism for machines for operating upon boot or shoe parts

Filed: 1920-06-10
Abstract: 168,988. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). June 10, 1920. Heels, machines for; uppers, machines for.- In a shoe machine wherein the work is introduced automatically between members separated to receive it and then closed upon it, means are provided to modify the speed of feed of the work in the course of the feed. The invention is shown applied to the heel-compressing machine described in Specification 23839/02, wherein a feed slide 14 is actuated by a lever 22, 24 pivoted to the reciprocating head and operated by a slot 26 engaging a pin at the end 24 of the lever, the slot being formed in a rod 27 sliding in a barrel 28 pivoted to the machine frame and housing a spring 30 normally pressing the rod 27 outwardly. Pivoted to the reciprocating head at 33 is a dog 32 having a spring normally retaining it in position to engage a roller 44 and move a lever 40 clockwise about its pivot as the head descends. When, during the descent of the head, the lever 40 is so moved, an adjustable link 47 connecting the end of the lever with a collar on the rod 27 depresses the rod against the spring 30 and causes a sudden reduction in the speed, or a cessation, of the feed by the slide 14. When the dog 32 has cleared the roller 44, the feed movement is increased in speed or resumed. The machine is thus enabled to deal with very high heels, which would otherwise foul the upper die while being fed into compressing position.
