Title: A process for the preparation of aromatic nitriles halogenated in the nucleus
IPC: C07C/
Filed: 1964-01-20
Abstract: Halogenated armoatic nitriles are made by the reaction of a halogenating agent other than a nitrogen oxide halide, in the presence of a tertiary amine, or an aromatic compound substituted in the nucleus with at least one nitro group and with at least one group having the structure-CH2R or a structure tautomeric therewith, R representing a hydrogen or halogen atom or a methyl or nitroso group. Thus, the group -CH2R may represent a methyl, ethyl, chloromethyl or bromomethyl group or a nitrosomethyl group or the oximinomethyl group (-CH:NOH) tautomeric therewith. The aromatic compound may be of the benzene, naphthalene, phenanthrene or biphenyl series and may be further substituted by halogen atoms or cyano, alkoxy, carbalkoxy or higher alkyl groups or additional nitro groups. The reaction involves the replacement of a nitro group by a halogen atom.  The halogenating agent may be a free halogen which may be formed in situ, e.g. from hydrogen chloride. Other specified halogenating agents are sulphuryl chloride, phosphorus pentachloride and thionyl chloride.  The preferred tertiary amines, which may be used in only catalytic proportions, are pyridine and its homologues, but other heterocyclic tertiary amines are also specified. The reaction may be effected at 120-240 DEG  C. at atmospheric, reduced or raised pressure in the presence or absence of a solvent, a number of which are specified, the gaseous halogen preferably being brought into contact with the molten or dissolved aromatic nitro compound. Water is preferably removed from the reaction mixture as it is formed, and the mixture may be irradiated with ultra-violet light.  Examples are given in which 2,6-dichlorobenzonitrile is produced from 6-chloro-2-nitrotoluene under various conditions, 2,6-dichlorobenzal chloride and 2,6-dichlorobenzyl chloride being obtained as by-products.  Other specified starting materials are 2- and 4-nitrotoluene, 2,4-dinitro toulene, 6-bromo-2-nitrotoluene and 6-chloro-2-nitrobenzyl chloride.  Specification 993,205 is referred to.

IPC: H01J19/00
Filed: 1959-01-23
Abstract: 904,506. Making grids for thermionic valves. STANDARD TELEPHONES & CABLES Ltd. Jan. 23, 1959, No. 2562/59. Classes 83 (2) and 83 (4). [Also in Group XL (a)] In a method of manufacture of a grid for a thermionic valve, portions are removed at regularly spaced intervals from both edges of a metal strip, the intermediate edge portions are rolled over so that they stand up from the same face of the strip, rectangular apertures are blankedout between each pair of opposite rolled-over edges and grid wire is wound over each aperture and bonded to the rolled-over edges before the grids so formed are finally severed from the parent strip. As shown, a molybdenum strip is fed intermittently through a blanking tool 9, Fig. 4, which removes edge portions 11 and punches out slots 10. The strip is moved forward by means of capstan wheels 12 whose spokes engage in the slots 10. The intermediate edge portions are turned up in a die 13, the strip is then annealed in oven 15 and a further die 16 rolls over the edge portions 1 into tubular or semi-tubular form. A blanking tool 17 cuts out rectangular apertures 3, Fig. 10, between the rolled-over edges and also apertures 18 and simultaneously forms the transverse members 2 into the required shape as indicated at 19, Fig. 11. The strip is then moved forward by means of belts 20 and blocks 21 which engage in the cut-away edge portions 11. A pair of printing rollers 22 gild the rolled-over edges 1, the gilt being set in oven 23. The frames then pass through a winding head 24 which carries a spool 25 of gold-plated tungsten wire. The frames are preferably stationary while the grid wire is helically wound over apertures 3, the winding head moving from right to left in the Figure. After the winding, the grids and head 24 move forward together until the head has returned to its initial position so that only a short length of wire joins consecutive windings. Rollers 28 apply glass powder or gold solder suspended in a binder to the edges of the winding, the grid wires being bonded to the frames in oven 29. Finally, a cutting head 30 severs the individual grids from the parent strip by removing the side portions adjacent cut-away portions 11.

Title: Colour television
Inventor: LIEBSCHER ARTHUR
IPC: H04N9/24
Filed: 1969-01-17
Abstract: 1,224,862. Colour television. A. LIEBSCHER. 17 Jan., 1969, No. 2883/69. Heading H4F. [Also in Division H1] The invention relates to a colour television tube for the simultaneous display of a number of colour signals without the need for a shadow mask. As shown, the tube comprises a means for generating three electron beams R, G, B, which are modulated at grids 3, 4 and 5 by signals representing the red, green and blue components of an image. The beams then pass through apertures in a plate 19, which serve to define the beam width, and on to a screen 11 via accelerating anodes 6 and 10 and beamdeflecting means 8 and 9. The screen comprises a number of strips of colour phosphors, alternating red, green and blue, at right angles to the direction of horizontal scan. Between each set of three colour strips a fourth non- luminous conductive strip 11a is placed, all such strips 11a being connected together and fed to a phase detector 18. The phase of the feedback pulses obtained when the electron beams scan the screen is compared with the phase of the third harmonic of a subcarrier oscillator 14. The resultant output of detector 18 is used to synchronize a 10À7 Mc/s. sawtooth generator 16 which applies a deflecting voltage to plates 8 for simultaneous horizontal deflection of the three beams. The coil 9 is provided with a raster deflection signal to control both horizontal and vertical deflection of the beams, the resultant of the deflections provided by plates 8 and coil 9 providing a simultaneous stepped horizontal deflection of the beams. The phase of subcarrier oscillator 14 is locked to the phase of the incoming colour subcarrier. In a modification (not shown), the striped colour phosphor screen is replaced by a uniform white phosphor screen which produces three white light beams corresponding to the three electron beams R, G, B and these light beams are projected on to: (1) a striped colour filter corresponding to the colour phosphor strrips described above or (2) a corresponding striped colour screen, the beam indexing signals being produced by an infra-red photo-electric detector responsive to thermal radiation produced when the light beams scan across indexing strips located between adjacent sets of three colour strips.

Filed: 1959-01-27
Abstract: 870,067. Mechanical coupling for cable sheathing. LIGHT & POWER ACCESSORIES CO. Ltd., and LOTT, F. J. Nov. 26, 1959 [Jan. 27, 1959], No. 2885/59. Class 38 (1). A flameproof gland for an armoured electric cable comprises a body 1 into which slides a sleeve 2A with a tapered end 7. A split tapered conducting collar 7, e.g. of lead, is forced into a tapered bore in a pressure ring 5C by a cap nut 5A screwed into the sleeve 2A. The collar 7 is thus compressed on to lead sheathing 6A on a cable 4D to form an earth contact and the ring 5C moves longitudinally to compress a neoprene seating ring 6 on to the sheathing 6A. The ends 10 of the wire armouring of the cable are clamped between the tapered end 4 of the sleeve and a tapered ring 9B by means of a cap 9 screwed on to the body 1. A neoprene washer 11B in the cap 9 is compressed by a cap nut 11A and a metal washer 11C to grip the outer sheathing of the cable. A neoprene ring 3A in an annular groove 3 provides a fluid-tight seal between the sleeve 2A and the body 1. The body 1 has a reduced diameter screw-threaded part 1A for screwing into a box and blind holes 1C to receive a turning tool. To allow for different diameters of sheathing soft metal tape may be wound round the sheathing or round the collar.

Abstract: 1,028,267. Multiplex numerical control system. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Jan 24,1963, ;No. 3052/63. Heading G3N. A time-division multiplex system for threedimensional control of machine tools comprises a number of input signal devices, such as the devices 11,12, including recording media in the form of punched tapes, and a number of controlled machines such as M1, M Synchronising circuits SYa-SYe receive the signals from the devices I1,12,and,by using two-phase synchronous pulses, generate two-channel time-division multiplex signals for application to circuit CL producing gate signals. The signals from the devices I1, I2, are also led to synchronizing circuits SY for generating time-division multiplex signals by the use of six-phase synchronous pulses. The output signals from the circuits SY are controlled in gate G so that only data components of the signals are permitted to pass through. These components are stored in six-channel register circuits R6. Gate circuits Gtx-Gtz for cutting-time control are associated with registers Rx-2-Rz-2 whose signals are read out at appropriate times to be introduced into logic circuit TL producing cutting-time command signals. A two-channel multiplex counter PCa carries out counting for pulse distribution whereby the pulse signal for cutting control is obtained. This signal is separated to provide control is obtained. This signal is separated to pro. vide control signals x10-z10 and x20-z20 for the two machines.
