Title: Improvements in and relating to electric pulse signalling systems
IPC: H04J3/04
Filed: 1948-02-04
Abstract: 638,897. Cathode-ray tubes. GENERAL ELECTRIC CO., Ltd., FARREN, L. I., HEAD, N. E., and LEVY, M. M. Feb. 4, 1948, No. 3276. [Class 39 (i)] [Also in Group XL (c)] A cathode-ray tube pulse generator and time modulator comprises means for deflecting the beam along a path passing recurrently over or close to a slot or strip electrode, means for deflecting the beam transversely with respect to said path and means to deflect the beam by the modulating signal to vary the point along the slot or strip at which the beam crosses it. In a multichannel arrangement, the beam describes a zig-zag'path crossing a plurality of slots or strips in succession. Thus two of the slots or strips 16, Fig. 2, are scanned by the beam which traces out a path 21 in the absence of modulation, the signal being used to deflect the path between limits 23, 24 and pulses being generated when the beam passes over the slots or strips. In one embodiment, the beam from gun 10, 11, Fig. 3, is swept by deflecting coils 12, 13 in a circular path over a plate 15 having a number of equally-spaced arcuate slots 16. The modulating signal is applied to a deflecting plate 18 of which one is provided corresponding to each slot while to the common deflecting electrode 17, in the form of a frusto-conical surface, is applied a symmetrical saw-tooth voltage derived by providing a further apertured plate 28, the apertures 29 in which are larger than the slots 16, Fig. 4, and the potential of which varies in square wave form (a). Fig. 5, as the beam traverses it. An integrating circuit 32 converts the wave form (a) to a sawtooth (b) which is amplified at 33 and fed to electrode 17. Negative output pulses are derived from target 25 arranged behind the slots or positive pulses from plate 15. The slots may be disposed so that their longitudinal centre lines are at some angle to the circle forming the centre line of the zig-zag. Radial screens are preferably introduced between the individual modulating electrodes 18 and also transverse screens 34, 35 having apertures 36, 37 respectively. In another embodiment three slots 16, Fig. 6, are arranged for operation with rectilinear motion of the scanning beam. A saw-tooth oscillation applied between electrodes 38, 39 deflects the beam slowly from left to right and rapidly from right to left, while a symmetrical saw-tooth oscillation of three times the frequency is applied to the interconnected electrodes 18. The path of the beam is hence slowly over the path 40 from left to right and rapidly over the return path 41. The slots 16 and apertures 29, 37 are of the relative shapes shown and screens 42 are disposed between adjacent modulating electrodes 17. The symmetrical saw-tooth scanning waveform is derived from the electrode with apertures 29.

Abstract: 1,011,664. Electrostatic precipitators. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 25, 1963 [Feb. 5. 1962], No. 3276/63. Heading B2J. [Also in Division G1] A detector of fission products in a gas comprises a conveyer member 1 with a plurality of zones on which ionized particles derived from the fission products are collected by electrostatic precipitation and a measuring apparatus such as a # scintillator 33 and a photomultiplier 35 located adjacent the conveyer member 1 for determining the radioactivity of each zone after collection of the particles, the conveyer member having a machined non-deformable plane surface on which the collection zones are located and being arranged to move in its own plane so that a further collection can be made upon a given zone only after a period of time sufficient for such zone to become substantially decontaminated by natural decay of the ionized particles previously collected. In the embodiment shown gas containing the fission products flows through a conduit 28 into a collection chamber 8 formed by an electrostatic precipitator consisting of a block of insulating material having a frusto-conical recess 23 on which is secured a metal electrode 27 having a part-spherical recess 26. A rotatable metal disc 1 forming a conveyer and the other electrode of the precipitator is positioned so that on an annular area of its rim coincident with the apex of the frusto-conical recess 23 circular collection zones, Fig. 1 (not shown), each correspond to the area of the apex. The disc 1 is driven intermittently by a motor so that each zone in sequence is positioned under the chamber 8 to collect ionized particles and is then moved to below a # scintillator 33, the resulting scintillators on which shine through a transparent conduit 34 to a photomultiplier 35. After each zone has completed its cycle and is again under the chamber 8 it has become substantially decontaminated by natural decay. In a further embodiment, the disc 1, Fig. 5 (not shown), is of insulating material, the collection zones are on a metallic layer formed on the annular area of the disc and the electrode of the precipitator is earthed, a negative source of high tension being fed to the metallic layer by a sliding contact. In another embodiment, Fig. 6 (not shown), the disc 1 is of insulating material and the collection zones are on a thin annular area and a negative electrode is placed below the chamber 8 under the annular area.

Filed: 1931-02-02
Abstract: 372,348. Television. FERNSEH AKT.- GES., Goerz-Allee, Zehlendorf, Berlin. Feb. 2, 1931, No. 3333. Convention date, Feb. 5, 1930. [Class 40 (iii).] In television, a synchronizing signal of constant frequency and duration transmitted at the end of each line, is selected by suitable filters at the receiver, rectified, and supplied to a synchronous motor, e.g. a La Cour wheel. The La Cour wheel responds only to the line frequency and not to the frequency of each individual signal. The synchronizing signals may be produced by scanning a grating placed at one side of the object or by impressing an oscillation from a generator directly on the transmitter at the end of each line. At the receiver, the selecting circuits may damp the oscillations so that they just reach their maximum during their duration.

Title: Improvements in or relating to machines for piling fabrics
IPC: D06B23/00
Filed: 1921-01-27
Abstract: 176,984. Saunders, B. H. Jan. 27, 1921. Piling materials in rope form. - In machines for piling fabric in a general star shape in which a feed-pipe delivers fabric in long lengths to a rotating and oscillating distributing-shoot, a separate and detachable guide-member is interposed between the feed and the distributing mechanism, the discharge shoot is automatically shortened and elongated as it swings, and itsthrow is adjustable. The mechanism for feeding the iabric which passes over the reel 16 is supported on a framework 10 carrying a pipe 12, which may have branch pipes supplying water or chemicals to assist the feed. A detachable pipe 25 connects the pipe 12 with the piling- mechanism, which is mounted on a frame 18 adapted to be fixed, for example, to a kier 9. A third pipe 24 fixed to the frame 18 carries a gearwheel 28 driven by a worm 29, so that the whole piling-mechanism including the discharge shoot 45 - - 48 and cam 53 is rotated. The shoot is oscillated up and down by the cam 53 engaging an arm 51 on the shoot, the cam being driven by engagement of the pinion 55 with a fixed gearwheel 56. The lower end 48 of the shoot is fixed to the gear-wheel 28 by a link 49, so that as the shoot swings up and down in its rotation to pile the fabric star-shaped the end telescopes over the part 45 of the shoot, thus automatically increasing and reducing the effective length of the shoot, so that the end of the shoot travels in an approximately horizontal plane. The shoot is supported by pivoted hinges 42 which, through a lever system and a hand-wheel 40, can be raised or lowered to regulate the inward and outward limit of the throw of the shoot. By turning the hand-wheel 40<a> the point of suspension of the shoot is thrown in or out with reference to the cam 53, and so the sector through which the shoot swings can be made greater or less. The teeth in the fixed gear is not a multiple of the teeth in the pinion, so as to get as large a cycle of distribution as possible.
