Title: Apparatus for reproducing the image of an instrument dial at a remote point
Inventor: YOUNG ROBERT ERIC
IPC: G01D5/39
Filed: 1952-02-25
Abstract: 742,983. Television. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. Feb. 25, 1953 [Feb. 25, 1952], No. 4851/52. Drawings to Specification. Class. 40 (3). In an arrangement for reproducing images of instrument dials &c. at a remote point by employing light generated by a cathode-ray tube "flying-spot" " scanner " and reflected or transmitted by the dials &c. to produce corresponding vision signals in a photo-electric cell, the cell is chosen to have a maximum response characteristic in the spectral region of the light generated by the cathode-ray tube. When a number of instruments which cannot be placed together are concerned, groups of them can be scanned by individual " scanners " and photoelectric cells, the outputs of which are mixed and the scanning is so arranged that each group occupies a part only of the picture reproduced at the remote point. The instruments (e.g. instrument panel in the case of an aircraft) and the signal generating equipment should, preferably, be enclosed in a light-tight box but if visual observation of the instruments is also necessary they may be illuminated by visible light of a different wavelength to that generated by the " scanner " an optical filter passing only light of the latter wavelength being interposed in the optical path to the photo-electric cell. Signals conveying other information (e.g. for telemetry) may be combined with the vision signals. In the case of " aircraft to ground " systems the synchronizing signal equipment may be located on the ground and synchronizing signals transmitted to the aircraft to synchronize the operation thereof. The receiving equipment may include provision for recording the reproduced images by means of a cinematograph camera in addition to a direct viewing picture reproducing cathode-ray tube. Specification 432,225 is referred to.

Title: Improvements in and relating to the mechanical filling of trucks or other containerswith coal or other solid substances
Inventor: SENIOR WILLIAM JAMES
IPC: B65G67/00
Filed: 1961-02-14
Abstract: 1,009,841. Loading trucks. AUTOMOTIVE PRODUCTS CO. Ltd. May 14, 1962 [Feb. 14, 1961], No. 5473/61. Heading B8E. [Also in Division B7] Apparatus for filling trucks with coal or similar solid substances is arranged so that the truck is filled to the desired level in turn at each of a plurality of positions lengthwise of a truck. Coal is supplied by a conveyer 3 to trucks 1 movable on rails 2 by belts 10 engaging- the side frame members. An hydraulic ram 6 lowers a shoot 4 into a position to deliver the coal into a truck or raises it so that the coal is diverted into an extension 9 while the trucks are being moved. An hydraulic control system is provided so that automatic filling of a line of trucks can be carried out. A first movement of a control lever causes a truck to be moved by the belts 10 to the position shown. A further movement of the control lever to the automatic position causes the shoot 4 to be lowered and delivery of coal starts when the conveyer 3 is operated. As the coal level rises pressure on a plate of the detecting means 13 causes a first valve to close to raise the shoot which movement continues until a desired level is reached when a second valve closes and causes hydraulic motors 11, 12 to drive the belts to move the truck until the pressure plate is free of the coal when the first returns to its original position and the shoot is again lowered and the cycle repeats. Arrangement is made as filling nears completion to prevent the shoot being lowered far enough to foul the rear end of the waggon and when filling is complete to bring the next truck into the initial position. In the raised position the shoot 4 delivers coal to an extension 9 which may by a further conveyer return it to the conveyer 3 or may deliver it to a previously loaded truck. If a belt 10 breaks, due to the normal incline on which the trucks rest, the other belt will be driven and the hydraulic fluid from a driven motor is used to operate a brake 15 to stop the trucks.

Abstract: 827,967. Luminescent materials. THORN ELECTRICAL INDUSTRIES Ltd. Feb. 8, 1957 [Feb. 22, 1956 ; Oct. 12, 1956], Nos. 5552/56 and 31206/55. Class 39(1). A luminescent material, particularly for use with discharge lamps or cathode-ray tubes or X-ray tubes, comprises a matrix consisting exclusively of thorium phosphate activated by up to 25% by weight of the matrix, of one or more of copper, cerium, antimony and lead. When only copper is present one or more of lithium, thallium and silver may also be present as additional activator(s). When the activators include copper and thallium, and/or one or more of cerium, antimony, and lead, the material can also include up to 10% of manganese, by weight of the matrix. Percentage ranges of proportions of the activators are stated. The material can be prepared by heating at a temperature of 800‹C. and then above 800‹C. up to 1260‹C. preferably in a mildly reducing atmosphere or steam, a mixture comprising a matrix consisting exclusively of thorium phosphate or a mixture of compounds that will form such a matrix on such heating together with the activator or activators in the form of a compound or compounds thereof. The mixture of compounds used to form the thorium phosphate matrix on heating may be one or more of the oxide, hydroxide, basic carbonate, oxalate, nitrate, &c., together with compounds of phosphorus such as an acid or oxide or an ammonium phosphate. Alternatively the mixture may combine a precipitated thorium phosphate with additional thorium oxide if necessary, or with an additional compound of phosphorus such as ammonium phosphate, if necessary. The compound or compounds of the activators can be oxide, hydroxides, basic carbonates, nitrates, halides, phosphates, acetates, sulphates, &c. The initial mixture can be prepared by co-precipitating together from aqueous solution, e.g. by adding a solution of a soluble phosphate to a solution containing thorium nitrate and the nitrate or nitrates of the activator or activators. In an example a mixture of thorium and copper phosphates are produced from a solution of the respective nitrates by the use of ammonium phosphate. Several specific examples are described.

IPC: H02H3/07
Filed: 1956-02-23
Abstract: 795,567. Protective cut-out systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 16, 1956 [Feb. 23, 1956], No. 5622/56. Class 38 (5). [Also in Group XL (c)] A protective system for an electrical apparatus such as a radio transmitter, has a first relay A which is operated on the occurrence of an overload or other fault to change over contacts A1. A second relay B is now energized from an external source 5 and opens contacts B2 to remove power from the apparatus and closes contacts B1 to cause current to flow through a thermistor 11. Relay A restores, but a series resistance-capacitor delay circuit maintains the relay B energized for a predetermined period during which the thermistor 11 is heated by the current flowing through it. If the fault persists, relay A is re-energized when the contacts B2 reclose so that the relay B is energized again and a further operating cycle occurs. If the fault still exists, a third cycle results in the thermistor 11 being sufficiently heated for its resistance to fall to a value such that a third relay D is operated by the current through the thermistor. The relay D opens contacts D3 to finally interrupt the supply to the apparatus, closes contacts D2 to complete a holding circuit and closes contacts D1 to light an indicating lamp 15. Resetting may be effected by pushbutton switches 14. The initial operation of the relay B may cause the operation of a fourth relay C which lights a lamp 10 to indicate the occurrence of a fault.

Abstract: 759,200. Coating by vapour deposition. BREW & CO., Inc., R. D. March 1, 1954, No. 5920/54. Class 82(2). [Also in Groups XXII and XL(b)] In joining two dielectric bodies, by coating a face of each body with a layer of ductile metal which may be 0À5-25 micron thick and cold pressure welding the layers, the coating is performed in an evaporation apparatus. The coating metal may be In, Sn, Ga, In-Sn-Ga alloy, In-1 to 3 per cent Ga alloy, In-1 to 5 per cent Sn alloy or Sn-4 per cent Ga alloy. In making delay lines each comprising a fused quartz block B joined to two quartz end plates C, an end surface of each of six blocks B and a surface of each of six plates C are chemically cleaned and the blocks are held in sleeves 35 and the plates are waxed to a glass plate 36 in a holder 31 in an evaporation bell 12. About 5À2 gram of 99À975 per cent pure In powder per cm<SP>2</SP> of surface to be coated is placed in a Mo boat 21 heated by current from leads 16, 17. Evaporation in vacuo at minimum temperature is continued until coatings 0À50-1À25 micron thick are deposited. The thickness of the coatings is determined by means of a transparent plate 46 which is also coated and allowed to become opaque to the source of light in the boat 21, when a known thickness has been coated thereon, the plate 46 being positioned at predetermined distances from the source of light and the surfaces of the blocks and plates, since the respective thicknesses are functions of the ratio of the distances of the surfaces from the light source. The coatings on each block and plate are cleaned and roughened by wiping with a cotton swab and thereafter cold pressure welded.
