Title: Improvements in or relating to time-base generators incorporating thermionic amplifiers
IPC: H03K4/20
Filed: 1945-05-15
Abstract: 592,372. Saw-tooth waveform generators. MACKAY, D. M., and WRIGHT, C. S. May 5,1945, No. 11510. [Class 40 (v)] A time base waveform with an expanded or contracted portion is generated by a thermionic amplifier with a capacitive feedback path between the output and input electrodes, the amount of 'feedback being changed during the time base sweep by adding or subtracting further capacitive elements by means of an electronic switch. In Fig. 1, network R1, C1 is the additional circuit element connected in parallel with condenser C in a "Miller" integrating circuit. Diode D is non-conducting at the incidence of the positive square wave at the suppressor grid of valve A, and R1, C1 is effective with condenser C in determining the rate of fall of anode voltage Va down to the level V1. Diode D then conducts and clamps the junction of R1 and C1 at the voltage V1, so that the network is ineffective for the rest of the discharge path which is consequently steeper than before. Alternatively, a second diode may replace resistor R1 which is then connected between the junction of the two cathode leads and the negative H.T. terminal. The initial discharge may be given the greater slope by reversing the diode connections, and returning resistor R1 to the positive H.T. terminal in the case of the double-diode arrangement. Fig. 6 shows a modification which produces a contracted portion within the operating range of anode voltage Va. When Va is greater than VI or less than V2, diode D1 or D2 is conducting and an additional circuit R1, C1 or R2, C2 is effective in the discharge circuit. When Va lies between V1 and V2, however, both diodes are conducting and the discharge proceeds at a higher rate since both networks are now ineffective. An expanded portion may be obtained between voltages V1 and V2 by connecting the anode and cathode of diodes D1 and D2 respectively to a single network R1, C1.

Abstract: 813,953. Particle accelerators. COLLINS RADIO CO. April 9, 1957, No. 11593/57. Class 39(1). A particle accelerator comprises an input cavity resonator formed with cylindrical cathode and grid sections which are direct current insulated from each other, a charged particle producing means mounted therein and a cylindrical output cavity resonator having an offcentre opening in alignment with the input resonator. A second source of charged particles is mounted in the output resonator and is connected to a phase control means so that it emits charged particles only at a time when they will be accelerated towards a target arranged in alignment therewith. The two resonators and the target are enclosed within an envelope. As shown, the cathode 11 and grid 12 are insulated from each other by a layer 21 of polystyrene and a bias voltage E c  is maintained therebetween to allow electrons to leave cavity 10 only during the positive peaks of input voltage. The voltage distribution within the output cavity 26 is such that a higher maximum voltage occurs at the centre than adjacent the edges so that electrons from the input cavity 10 give up their energy to output cavity 26 at a low voltage point while electrons from the second source, electron gun 32, enter cavity 26 at a time, determined by phase control 38 and probe 37, when they will be accelerated by the higher potential existing in the centre of the cavity. The accelerated beam may be used, for example, to bombard a target 36 or to generate X-rays. U.S.A. Specification 2,641,733 is referred to.

Abstract: 854,462. Electric programme systems; electric correspondence control systems. BRITISH IRON & STEEL RESEARCH ASSOCIATION. April 10, 1957 [April 19, 1956], No. 11954/56. Classes 38 (6) and 40 (1). [Also in Groups XXII and XXXV] In an electrical control circuit for say the screwdown motors of a steel mill having a plurality of combinations of control states responsive to factors such as weight of ingot, final size of bloom required, number of passes &c., uniselectors are used in place of a multiplicity of relays for translating the input conditions into output connections suitable for controlling the motors or other devices. In the embodiment given, the input conditions are set on multi-position switches which are connected to input uniselectors which step in unison to a position corresponding to the input conditions. The input uniselectors are connected to output uniselectors which give the required connections to perform the control operations. In the Figure, a slider d of a potentiometer d, e is connected to an amplifier a controlling a motor b driving the screw-down mechanism c to which is attached the slider d. A series of pairs of resistors r 1 , r 2  of differing ratios forming dividers are connected to pairs of output uniselector contacts P1-50, Q1-50, and their mid-points to slider d, thus the screw-down mechanism will take up a position corresponding to the pair of resistors connected to wipers P, Q, the position of which is determined by an input selector which is stepped at each pass. Random movements of the motor b are prevented by a relay contact LL1 which is opened when the roll setting is altered.

[Class 2 (ii)] [Also in Group VIII] A cellulose derivative composition for use as a moisture-proofing coating composition or for making films comprises a wax or wax-like material, a gum or resin, and a polymer of a methacrylic ester containing an aliphatic group of 3, 4, 5 or 6 carbon atoms. The aliphatic group may be an alkyl or cyclo alkyl group. The cellulose derivative may be a nitrate, acetate, or other ester or a benzyl, ethyl, hydroxy ethyl, or other ether, or a mixed ester, ether, or ester-ether. Cellulose nitrates of 10.5-12.5 N content may be used. The. wax or waxy material may be paraffin, carnauba, candelilla, ceresin, Japan, palm, beeswax, Chinese insect wax, petrolatum, chlorinated hydrocarbons, or a synthetic wax. The gum or resin may be a rosinate, alkyd resin, polyvinyl resin, chlorinated diphenyl, phenol-formaldehyde, dammar, copal, kauri, ester gum, or "Beckasite" 1110 (Registered Trade Mark) which is an ester gum-rosin and maleic anhydride glyceride mixture. The composition may contain oils, dyes, or pigments. A plasticizer, such as tricresyl phosphate, dibutyl phthalate, di-cyclohexyl phthalate, di-(dimethyl cyclohexyl) adipate, or butyl benzoyl benzoate may be present. Normal or iso-butyl, normal or iso-propyl, amyl, hexyl, or cyclo-hexyl methacrylate polymers may be used. Inter-polymers such as methyl-butyl or ethyl-butyl may be used. The composition is preferably used in solution in a solvent or mixture of solvents, e.g., ethyl acetate, toluene, and ethanol. The composition may be applied as a coating to sheets or films of regenerated cellulose ; cellulose acetate, nitrate, or other ester ; benzyl, or other cellulose ether ; gelatin, or casein. The composition may be cast or otherwise formed into self-supporting films. The compositions impart good heat-sealing properties to sheet wrapping-material coated with them. The films or coatings have less tendency to stick to metals such as parts of wrapping machinery with whicb they may make contact than films or coatings which do not contain the polymethacrylic ester constituent. The coated regenerated cellulose sheets are particularly suitable for wrapping food products such as butter, fish, or cheese. Specifications 283,109, [Class 2 (ii)], 395,687, and 437,284, are referred to. The Specification as open to inspection under Sect. 91 comprises also the use of ethyl and lauryl methacrylate polymers and a polymer of methacrylic lauryl-imide as ingredients of the cellulose derivative compositions. This subject-matter does not appear in the Specification as accepted.
