Title: Signal converting cathode ray tube
IPC: H01J31/64
Filed: 1966-07-26
Abstract: 1,145,146. Cathode ray tubes. HUGHES AIRCRAFT CO. 26 July, 1966 [2 Aug., 1965], No. 33487/66. Heading H1D. A scan-frequency conversion tube comprises a target consisting of a mosaic of dielectric regions co-extensive with the apertures in a metallic mesh 30, writing and reading guns 16, 14 and a flood gun 42 for effecting erasure of the charge pattern. The mesh 30 is coated with a thin layer of gold on the side facing the writing gun and a thin film of collodion is stretched over this side of the mesh. Thereafter a layer 34 of dielectric, e.g. zinc sulphide, is evaporated over the film of collodion and the gold coating is diffused into and through the dielectric. The target therefore consists of discrete storage areas visible to both electron guns. The beam velocity of the reading gun 14 is such that there is no secondary emission from the target. This becomes charged negatively and reading beam electrons are collected by a collector mesh 381. The writing gun 16 is operated at a negative potential with respect to the target and the beam velocity is such that secondary electrons are emitted from the target whereby discrete areas are variably raised in potential in accordance with the modulation imposed on the beam. This causes a similar variation in the proportion of reading beam electrons landing on the target and on the collector (output) mesh 38. Erasure is effected by pulsing the control grid 50 of gun 42 which causes the target to be flooded with low-energy electrons whereby its potential is lowered to that operative before writing.

Title: A means for severing or separating printed patterns or designs from a printed sheet or a strip of paper transfers
IPC: B44C1/16
Filed: 1947-12-19
Abstract: 647,276. Severing non-metallic sheet material by burning. JOHNSON BROS. (HANLEY), Ltd., and BIRD, G. W. Dec. 19, 1947, No. 33614. [Class 31 (i)] [Also in Group XI] A device for separating from a printed sheet or a strip of paper transfers, the area defined by each pattern or design, comprises a plate 5 of ceramic material having an electric resistance 6 attached to one of its surfaces and arranged so as to surround the area defined by the pattern or design, the plate being movable towards and away from a support having a non-inflammable surface on which a printed sheet or transfer paper may be placed and against which the plate is pressed to move the resistance element into contact with the printed sheet or transfer to separate the pattern or design by burning. The element may be in the form of a wire which is of small mesh size or has a knife edge part for contacting the paper. Alternatively the element may be in the form of a thin metal strip or ribbon 6 partly embedded in or secured to the ceramic plate 5. The strip 6 may be bent into angle section, one of the flanges serving to anchor the strip to the base-plate. A rib-like part 19 ensures that no part of the base comes into contact with the design printed on the sheet so that smudging is prevented and any possibility of adhesion between the sheet and the base eliminated. In the apparatus shown in Fig. 3 an intermittently-driven endless belt 28 conveys the sheet 39 step-by-step below the separating device 5, the 'conveyer belt being made of asbestos fibre or other non-inflammable woven material. The transfer strip is held flat on the conveyer belt by suction created in a chamber 32 by a vacuum pump 34 which draws air through a perforated table 31 (forming the top of the chamber 32) dnd also through the fabric belt above it. The separating device 5 is reciprocated vertically either by means of a handle 22 or automatically in synchronism with the movement of the conveyer belt.

Abstract: 669,834. Automatic volume control. BRITISH THOMSON-HOUSTON CO., Ltd., and THOMAS, D. C. Dec. 9, 1949 [Dec. 31, 1948], No. 33647/48. Class 40 (iv). [Also in Group XL (c)] The gain of an amplifier is controlled according to a given function by applying to the input of the amplifier a control frequency which is amplitude modulated according to a function which at any instant is the reciprocal of the given function, the output of the amplifier being maintained constant at the control frequency and the band-width of the amplifier being such that it passes both the control frequency and the carrier frequency it is required to amplify. The control frequency output voltage is maintained constant by means of an automatic gain control system the control voltage of which may be applied to the auxiliary grids of the amplifying valves. The system may be used for simultaneously controlling in accordance with a desired function the gain of a number of amplifiers, the modulated control frequency being applied to each amplifier and a separate A.G.C. system being provided for each. The gain of the series of amplifiers may be kept constant at the carrier frequency to be amplified if the desired function is a constant. The control frequency may be amplitude modulated by means of a cathode-ray tube in which the ray is constrained to trace the contours of a template by means of an electronic servo system as described in Specification 607,397, [Group XL (b)].

A semi-conductor device includes a monocrystalline semi-conductor body secured to one face of a metal plate, the opposite surface of which is in pressure contact with another conducting member. One of the surfaces in contact consists of gold, silver, or platinum, at least one of the surfaces is uniformly pitted to a depth of 0.5 to 50Á and both of the surfaces deviate from a plane by less than said mean pit depth. In making a typical device, Fig. 4, a sub-assembly is first made by heating to 800 C. superposed discs of molybdenum, aluminium, 1000 ohm.cm. P-type silicon and gold-antimony alloy pressed together in graphite powder. After lapping the upper and lower surfaces of the sub-assembly to form suitably rough surfaces and etching to expose the surface of the PN junction formed, the surface is oxidized by treatment in dilute etchant or etchant vapour. The sub-assembly is mounted with a silver foil 7, 100-200Á thick and having honeycomb pitting on its surfaces, on copper stud 2. A brazed up sub-assembly consisting of a copper rod 8 and ring 11 and molybdenum disc the surface of which is silver-plated and lapped to the requisite roughness is then clamped to it by inverted cup 17 containing diaphragm springs 13-16 and a mica centring washer 12. The upstanding ring 3a on the stud is beaded over the flanged edge of the cup to maintain the required pressure which will be greater if any of the contacting surfaces are slightly non-planar. An outer casing built up of iron-nickel-cobalt parts 18, 20 and metallized ceramic ring 19 is then clamped to the stud by beading over rim 3b. In an alternative arrangement the sub-assembly has similar molybdenum plates 4, 10a on both faces (Fig. 5) to permit mounting with either pole in contact with the stud. Graphite particles may be included between the molybdenum plates and the stud 2 and contact 8a to permit easier sliding movement of the surfaces. The PN junction is coated with a silicone lacquer containing alizarin and a mass 23 of resin cast about it. A germanium wafer with electrodes of indium and lead arsenic alloy and a carrier plate of high cobalt and nickel alloy steel may be similarly mounted. Use of silicon carbide and A m B v  and A n By i  as semiconductor is also envisaged as is the mounting of transistors, 4 layer semi-conductor thyratrons, photo-transistors, and multiple arrangements consisting of several diode or transistor elements in a single body.

Abstract: 1,067,320. Track apparatus. GENERAL ELECTRIC CO. Aug. 6, 1965 [Aug. 7, 1964], No. 33854/65. Heading B7N. [Also in Divisions H3 and H4] An object to be identified, such as a railroad car, carries a signal reflecting device comprising an aerial 14, a tuning capacitor 15, and a piezoelectric transducer 16 mechanically coupled to an acoustic delay line 17 which has impedance discontinuities arranged along its length according to a predetermined code. A fixed aerial 12 is connected via an amplifier 11 both with a transmitter 10 and a receiver 13 and becomes inductively coupled with the aerial 14 when the object is near. The transmitter 10 is pulsed and its frequency is swept over a range including the frequency at which the signal reflecting device resonates, when sonic pulses are set up in the delay line 17. Each sonic pulse causes a reflection at each impedance discontinuity in the line 17 and, in consequence, an electrical pulse in the aerial 14, leading to re-radiation into the aerial 12 and detection by the receiver 13. Thus, following each transmitted pulse, there is received a train of pulses with time separations according to the predetermined coding. The delay line (17) may consist of a wire and the impedance discontinuities may be notches (18), Fig. 2(a) (not shown), or clamps (19), Fig. 2(b) (not shown), or beads (20), Fig. 2(c) (not shown). The delay line (17) may be formed into a flat coil and be supported on acoustic insulating blocks (28), Fig. 5 (not shown). The piezo-electric transducer 16 may comprise a crystal (21) Fig. 3 (not shown), clamped or bonded between a metal plate (22) and a metal conical member (23), or it may comprise a moulded cylindrical ceramic element (26), Fig. 4 (not shown), placed around the delay line (17) and covered by a metal cylinder (27).

Abstract: 312,198. Knauss, H. A. Dec. 15, 1927. Records, duplicating.-A method of making a replica in metal, such as copper, of indentations, grooves, or relief marks in the surface of a body of material transparent to X or like rays, particularly applicable to duplicating sound records, consists in filling in the depressed portions of the surface with a substance such as barium sulphate, which is substantially opaque to the rays, making a contact print upon a sensitized carrier, by transmitting X or like rays through the prepared surface, and thereafter transferring the impressions to a metal surface by photo-chemical means. In applying the process to sound-records, soundgrooves 12 are made in the usual manner in a body 11 of wax or the like, and the grooves are filled in with a " radio opaque " substance. The surface is made perfectly level, and a protective shield 14 is fixed over the grooves. Then, preferably after the thickness of the wax body has been reduced, it is placed in contact with a photographic plate or film 15, Fig. 5, and exposure to rays from an X-ray tube or the like 17 is made. After development, &c., the negative thus made, or a positive produced therefrom, is printed on to a copper plate having a sensitized surface emulsion, and by subsequent etching in an acid bath, a replica of the sound-grooves, or a relief copy, is produced on the plate. The copper plate may be directly used for sound-reproduction, or a matrix may be prepared therefrom for duplicating the records by a moulding process. The originally produced wax master may be a record either of the lateral-cut or hill-and-dale type.
