Title: Improvements in or relating to vhf radio communication systems
Inventor: GRISDALE GEORGE LAMBERT
IPC: H04B7/10
Filed: 1963-06-24
Abstract: 1,089,782. Aerials. MARCONI CO. Ltd. April 23, 1964 [June 24, 1963], No. 24960/63. Heading H4A. The radiation pattern from vertical stacks 1TA, 2TA ... of dispoles is orientable by a system of frequency-changers 1FC, 2FC ... connected in parallel to a modulated radiofrequency source TD or output and connected to an oscillator TO via an adjustable phaseshifter TP which, in any given position of adjustment, affords the same phase difference between the oscillations fed to frequencychangers which are coupled to adjacent stacks of the aerial system. The invention is particularly applied to a ground station communicating with distant aircraft. In the ground receiving system, each one of 20 vertical stacks of dipoles feed its own coupling amplifier and those amplifier outputs are fed to all of n receivers, the heterodyning oscillations in a receiver being associated with a phase shifter having 20 outputs the phases of which inter se are the same in a receiver but different as between receivers, Fig. 2 (not shown). The receiving aerial may comprise such a greater number of stacks of dipoles than the transmitting aerial as will allow for the lower transmitter power on the aircraft.

Abstract: 259,597. American Type rounders Co., (Assignees of Kelly, W. M.). Sept. 9, 1924, [Convention date]. Gripper mechanism; tripping-arrangements.-A cylinder printing-machine of the oscillating-cylinder type is fitted with grippers which are normally spring-closed and are adapted to be closed quickly for feed and opened quickly for delivery, by means of a pair of movable cams operated by the machine, the grippers being closed just subsequent to the moving of the cylinder to impression position. The invention is described in connection with a machine as set out in Specification 240,145, in which a reciprocating bed 15 moving in an inclined track co-operates with an oscillating cylinder 33 fitted with grippers 58 mounted on a spring- controlled shaft 59. The grippers 58 are opened to receive the sheet by a cam 61 on a ring 65 rotatable on an inner shouldered ring 66, the ring 65 being oscillated by a cam 73 acting on a lever connected by a link 68 to the ring 65. The cam 73 is mounted on a shaft 22 on which is also mounted a cam 45 which controls lever-and-link mechanism 47. 48. 51. 54 for operating eccentric bearings 43 in which the cylinder 33 is mounted. The cylinder is thrown " on " prior to the moving of the ring 65 in an anticlockwise direction to cause the grippers to close quickly on the sheet. A second cam 62 on ring 65 controls the opening of the grippers for delivery, the ring 65 being moved clockwise by the high part 75 of cam 73 to open the grippers quickly.

The strength imparting resin is selected from polymers of ethyl acrylate and ethylhexyl acrylate and copolymers thereof with methyl methacrylate or polyvinyl acetate, styrene/butadiene copolymers, polymethylmethacrylate, urea formaldehyde and melamine resins. The impregnation may be effected by passing the laminate through the suspension containing 5 to 50% by weight of resin at a rate sufficient to contain a wet pick-up of 75 to 250%. The saturated laminate may then be dried at 240 to 350 F. for two minutes to remove water and cure the resin and provide a laminate with a resin content of 10 to 30% by weight. Softeners such as glycerine or polyethylene glycol may be incorporated.

Abstract: 891,179. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 15, 1960 [July 24, 1959], No. 25470/59. Class 39(4) A nuclear fuel element comprising a nuclear fuel member capable of taking up oxygen on heating and enclosed in a protective sheath is made by evacuating the sheath after insertion of the fuel, followed by filling the sheath with a mixture of helium and oxygen, oxygen predominating, up to at least atmospheric pressure, completely sealing the sheath, and then heating the fuel element so that oxygen is taken up by the fuel. This prevents leakage into the element of unwanted gases during manufacture and generation of excess pressures during reheating. A suitable gas mixture contains 5% helium and 95% oxygen by volume.

Abstract: 1308948 X-ray crystallography S ABRAHAMSSON 27 May 1970 [30 May 1969 13 Feb 1970] 25585/70 Heading G1A An apparatus for monitoring accurrence of respective events at a plurality of positions comprises a like plurality of detector elements (discrete areas of a fluroescent screen) responding to the respective events which elements are coupled with respective signal integrating elements and means for determining whether or not the individual time integrals exceed a predetermined value at a selected instant. In a crystallographic x-ray analysis method and apparatus, Fig. 1, in which deffracted x-rays C R  from a crystal C on a step rotatable table 4 cause fluroescence on a screen 5, the screen is coupled by fibre option 10 to the input elements of an image intensifier 15 wherein the light on elements of screen 5 is integrated. The intensifier output is converted to a video signal by a vidicon 17 and passed after amplification to an amplitude, discriminator 11 which produces an intensity output on line 21 when the signal has exceeded at least one predetermined output an output on line 20 whereby the co-ordinates of the area giving rise to the signal are determined from the vidicon scanning control 19. The signals are fed to a computer 1 either directly or from a store 25. The computer may control the x-ray source 2 and the dwell time of the crystal steps. The integration time of the signals detected by the vidicon is determined by an exposure control circuit 30 in response to digital information from the computer, the circuit developing scan initiating and blocking signals. The apparatus may be applied to reading a mass spectro-meter.

Abstract: 1330628 Seismic prospecting TEXACO DEVELOPMENT CORP 1 June 1972 [13 July 1971] 25633/72 Heading H4D A method of offshore seismic exploration permitting both shallow-reflection profiles and deep-reflection profiles to be recorded during one traverse of a profile line, without substantial interference of one profile type with the other, comprises periodically recording deep-reflection profiles using a large energy shot fired at relatively long intervals, and recording shallowreflection profiles using a small energy shot fired at relatively short intervals, the small energy shot being fired only when no deep reflection profile is being recorded. In the Fig. 4 embodiment the large energy shot, provided by a pair of towed air guns, is fired at instants 76 followed by respective deepreflection profile recording periods 75. During these periods a sequence timer produces a signal 77 which inhibits firing of the small energy shot. On cessation of signal 77, keying pulses 83 from a shallow-reflection chart recorder trigger the firing of the small energy shot (provided by a small air gun near the towing ship) at instants 80 each followed by a shallow-reflection recording period. The chart recorder print action and paper drive are inhibited during periods 84. Reference time lines are also recorded.
