Abstract: 670,231. Aerials. BRITISH THOMSONHOUSTON CO., Ltd. May 13, 1947 [May 13, 1946], No. 12922/47. Classes 40 (v) and 40 (vii). A wide-band aerial for radiating horizontallypolarized waves omnidirectionally in the horizontal plane comprises a plurality of radiating elements forming a concentric loop about an earthed conductive mast upon which they are conductively supported, certain pairs of adjacent elements being energized at their adjacent ends and the remainder of the elements being capacitatively coupled to the adjacent ones of the energized elements. The capacity between adjacent elements and the manner of feeding the aerial is so arranged that each element carries substantially the same current both as regards amplitude and phase. The aerial comprises arcuate members 29, 30, 33, 34, 35, 36 supported from the mast 1 by arms 25, 26, 27, 28. A radiating fin, 31, 32 or 37, is attached to each arcuate member to increase the current-carrying surfaces thereof and thus improve the broad-band characteristics of the aerial. Energy is supplied to the aerial via coaxial feeders 38 and 40 which are coupled to the adjacent ends of members 33, 34 and 35, 36, respectively. Line - balance converters are mounted within the arms 26, 28 for coupling the unbalanced coaxial feeder to the balanced aerial system. Members 29 and 30 are coupled capacitatively to the adjacent ends of elements 34 and 35 and elements 33 and 36 respectively; auxiliary discs may be mounted on the ends of the members to increase the coupling between them. The line-balance converters may be set to behave as inductances in series with the aerial inputs in those cases when the aerial impedance has a capacitative component. Fig. 1 (not shown) illustrates an alternative arrangement. In this arrangement, which is electrically equivalent to that of Fig. 3, various mechanical modifications are made; thus the radiating fins shown in Fig. 3 are replaced by rod or tubular members which are attached at each end to a corresponding end of the respective arcuate members.

Patent GB-1401743-A (GB)
Title: Colour target and method of manufacturing same
IPC: H01L27/146
Filed: 1973-03-19
Abstract: 1401743 Photo-sensitive semi-conductor devices; image pick-up tubes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 March 1973 [17 March 1972 10 Nov 1972] 13121/73 Headings H1K and H1D Each element of a photo-sensitive semiconductor target for an image pick-up tube (e.g. of the iconoscope type) comprises a first relatively shallow P-N junction and a second, deeper P-N junction. The shallow junctions of all the elements are at the same depth and perform the conventional photo-electric function. The second junctions, defined by regions 25-27 (Fig. 4(g)), occur at three different depths and have the function of preventing charge carriers generated relatively deeply within the semi-conductor body from contributing to the photo-electric output across the shallower junctions. Since, according to the specification, the depth of penetration of light is a function of wavelength, at least in Si, the varying depths of the second junctions produce different spectral sensitivity peaks in the various elements. It is stated that the elements having the shallowest second junctions (2-4Á deep) are responsive to blue light only, the elements having slightly deeper second junctions (5-7Á) respond to blue and green light and the elements with the deepest second junctions (10-12Á) respond to the full spectrum. Suitable subtracting circuitry generates the three primary colour signals. Fig. 9 (not shown) is a block diagram of scanning circuitry suitable for use with a tube containing a matrix target (71) according to the present invention. The system includes a vertical scan generator (72) which operates transfer gate (73) when charges accumulated in the matrix (71) are to be transferred through output resistor (74) to output amplifier (75).  The embodiment shown in Fig. 4, is made by etching grooves of varying depths in a P-type Si body 20, depositing As-doped N-type Si epitaxially onto the entire upper surface, including the grooves and etching the resulting structure to form a flat upper surface. B is diffused into the islands 25-27 to form the shallow junction regions 30. After removal of unwanted B-glass and formation of electrodes 31-33 a layer 35 of antimony bisulphide is evaporated over the surface. In Fig. 6, the structure is similar, but the grooves are run together and a series of charge transfer electrodes 33 are used to transfer information about incoming radiation. The sensitivities of the target to the various colour components may be matched to those of the eye.

Abstract: 781,560. Blow-moulding plastic bottles &c. GLENN PROPRIETARY, Ltd., L. & I. Nov. 18, 1954 [Dec. 24, 1953], No. 13281/56. Divided out of 780,439. Class 87(2). A machine for extruding a tubular length of plastic material and blowing it into bottle &c. shape is made by converting known injection-moulding machines of the type having a flxed platen 47, Fig. 2, a movable platen 46 and an injection cylinder 48 in which works a ram 55. The conversion involves removing the usual mould parts from the platens, removing the injection nozzle, fitting an extrusion-plus-blowing nozzle 56 to the cylinder and securing bottle mould halves Ma, Mb to the platens. Pressure pads 60 are secured to the platens to allow for the off-centre setting of Ma and Mb. In operation, ram 55 is moved to the left to extrude a tubular plastic length through nozzle head 56a, the extruded length being disposed between Ma and Mb. Then platen 46 is moved to the right by a hydraulic-plus-toggle arrangement to close Mb against Ma about the tubular length, the nozzle and cylinder being pushed back against the resistance of a spring 67a, and-guide pin 63 on the nozzle entering guide bush 64 on platen 46. Compressed air is then blown through the hollow nozzle core 56b to expand the length to bottle shape, platen 46 retracts to the left and ejector pins 57 carried by a spring-pressed plate 59 discharge the bottle from the mould. The nozzle 56 may feed two or more nozzle heads 56a, Fig. 3, the feed to each head being controlled by screws 74. Fig. 4 shows a modification in which the cylinder 48 and nozzle 56 are stationary, Ma being pivotally mounted at the lower ends of bell-crank levers 68 fulcrummed at 69 on stationary platen 47. The upper ends of levers 68 are adjustably connected to movable platen 46. As platen 46 moves to the right, Ma is moved to the left by the levers. Fig. 6 (plan) shows a modification in which Ma and Mb slide towards and from each other on rails 72, being moved by inclined dowels 73 which are fixed to movable platen 46 and enter slots in Ma and Mb. In a modification of Fig. 6, Figs. 7 and 8 (not shown) the machine is a vertical one, the movable platen rising to close the mould sections and the dowels extending upwardly therefrom. In a further modification, Fig. 9 (not shown), the machine is in general horizontal but the cylinder is vertically disposed. In other modifications (not illustrated) the moulds or nozzle heads may be moved by pneumatic or hydraulic cylinders.

Abstract: 563,075. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 21, 1940, No. 13289. Convention date, Oct. 19, 1939. [Class 40 (v)] A four-course radio beacon comprises two pairs of radiators 101, 103 and 102, 104, each radiator radiating horizontally polarized waves and being arranged at the corners of a square, the diagonal of which is about a half wavelength. A carrier-frequency generator 110 is alternately connected by switch 111 and shielded transmission lines 105, 107 to the pairs of radiators so that intersecting radiation patterns of horizontally polarized energy are produced. The radiators of each pair are spaced apart by half a wave-length and energized in phase opposition (because of the transposition at 108) so that each pair produces a figure-of-8 radiation pattern. The two figureof-8 patterns overlap so that four guide lines are provided where the 'signals from two adjacent radiators will be equal. Each radiator comprises four radiating conductors 1, 2, 3, 4, opposite conductors 1, 3 and 2, 4 being energized in phase opposition. The overall length of each conductor is about one half the wavelength, the radiating portions of the conductors being less than a quarter of a wave-length, so that the radiating portions are uniformly energized. The keying means 112 may produce A-N or other interlocking signals. To 'avoid distortion due to reflection or re-radiation by adjacent objects, the radiators are at some height above the earth's surface and a conducting screen 210, Fig. 2, is arranged between the radiators and the cross-connections 207, 208 connected to the transmission lines 211, 212. The screening of the connections 207, 208 extends through the screen 210 up to the radiators. The construction of the individual radiators, such as 101, is more fully described in Specification 538,036.
