Abstract: 1487600 Semi-conductor devices; varistors GENERAL ELECTRIC CO 12 Nov 1974 [12 Nov 1973] 48854/74 Heading ClJ [Also in Division H1] The size of grains 17 in the sintered body 11 of a varistor 10 is controlled by including a grain growth inhibitor material in an intergranular matrix at least partially bounding each grain. In one embodiment, Fig. 2, the body 11 is formed by mixing together a major part of ZnO with the oxides of bismuth, manganese, cobalt and titanium, the latter acting as a grain growth stimulant. The oxides are wet-mixed and spray-dried to form agglomerates which may be sifted if a uniform grain size is desired. These are then coated with the grain growth inhibitor, e.g. by tumbling, which may be an oxide of chromium, manganese, bismuth, boron, nickel or antimony. The body is shaped by pressing and is then sintered at 1180-1300C. when grain growth occurs within the coated agglomerates. Such growth may result in monocrystalline grains 17. In an alternative embodiment, Fig. 3, the varistor body comprises a laminated structure of granular metal oxide powder 17A and grain growth inhibitor 18A with or without the same metal oxide. The regions 17A may also grow to become substantially monocrystalline when the body is sintered.

Apparatus for slotting box blanks comprises a plurality of knife assemblies 10 mounted on a rotatable main shaft 11 and each including a flanged hub 12 rotatable with the shaft and having a knife element 13 fixed thereto, an internally geared annulus 14 mounted coaxially on the hub 12 so as to be freely rotatable thereon and having a knife element 15 fixed thereto, a pinion 17 meshing with the teeth of the annulus 14 and a pinion shaft 18 coaxial with the pinions 17 and rotationally fixed thereto, a brake ring 19 provided on the annulus 14 of the knife assembly 10a, or an annulus (29), Fig. 3 (not shown), of an equivalent assembly not equipped with knife elements but to which the pinion shaft (18) extends, and a brake shoe 20 carried by an extension 21 of the fixed main frame 22 of the apparatus and arranged so that it can be brought into engagement with the brake ring 19 to prevent it from rotating with the assembly on which it is carried so that rotation of the shaft 11 will cause the associated pinion and pinion shaft to rotate and thereby through the intermediaries of the pinions of the, or of the other knife assemblies move the associated annuli rotationally relative to the flanged hubs thereby changing the circumferential spacing of all the in-line knife elements. The brake is preferably engaged by remote control. A friction clutch 23, 24, 25 is provided to prevent the pinion shaft 18 from rotating relative to the knife assemblies when the brake is out of action. The knife assemblies and associated pinions are axially slidable on the pinion shaft. The pinion shaft is provided with means 32 whereby it can be turned by a handtool. A scale or pointer associated with the brake ring extension of a geared annulus is set against a pointer or scale associated with the hub, to indicate the amount by which the knife elements of the associated knife assemblies are circumferentially spaced. Alternatively, the circumferential spacing of the knife elements of the knife assemblies may be adjusted simultaneously by adjusting the main shaft rotationally relative to its driving means and the blank feeding mechanism associated therewith. For this purpose, a driving gearwheel 33 is rotationally fixed to the shaft 11 through the intermediary of gearing elements 34 supported from the flange 35 of a hub member 36 which is keyed to the shaft 11, the elements 34 being operable by an electric motor 37 actuation of which causes the hub member 36 and the shaft 11 to rotate slowly relative to the gear wheel 33. A scale 38 associated with the gear wheel 33 is set against a similar scale 39 associated with the shaft 11 and its hub members 12 to show the amount by which the knife elements are circumferentially spaced.

Abstract: 1,114,513. Cooling electron discharge tubes. ENGLISH ELECTRIC VALVE CO. Ltd. 2 Nov., 1966 [24 Nov., 1965], No. 50004/65. Heading F4U. A cooling system for an electron discharge tube comprises a boiler 1 in which part of the tube is immersed and in which a constant liquid level 17 is maintained by causing excess coolant to by-pass the boiler. Heating of the excess coolant is thus avoided. As shown in Fig. 3 the coolant supply pipe 14 has two branches 15 and 16, the former supplying the boiler and the latter extending upwardly into a vessel 18 which is open to atmosphere through an aperture 20 and has an outlet 19. The level of the top of branch 16 thus defines the liquid level 17 in the boiler. The vapour outlet 21 of the boiler communicates with a condenser 4, Fig. 4, condensate from which mixes with liquid from outlet 19 flowing through finned pipes 23 to a reservoir 2. A pump 3 supplies liquid from the reservoir to pipe 14 via a jacket 6 surrounding a further part of the discharge tube. In a modification (Fig. 5, not shown), pipe 14 discharges into the bottom of the vessel 18 which is connected to the boiler and contains a weir defining the boiler liquid level.

Title: Manufacture of carbon fibre
IPC: D01F9/32
Filed: 1972-10-31
Abstract: 1443935 Carbon fibres NATIONAL RESEARCH DEVELOPMENT CORP 30 Oct 1973 [31 Oct 1972] 50046/72 Heading C1A In a process for the pre-heating and oxidative treatment of continuous lengths of acrylic fibre, under tension, for use in the production of carbon fibre, the tension maintained on the fibre is such that substantially no shrinkage occurs during pre-heating of the fibre up to the temperature for the oxidative treatment and such that any subsequent shrinkage occurring in the oxidative treatment step is at least equalled by extension of the fibre during that step, so that there is no overall shrinkage of the fibre during the pre-heating and oxidative treatment steps. Preferably, the tension is such as to result in the fibre after oxidative treatment being of substantially greater length than the fibre before treatment. Oxidative treatment may be followed by carbonization in a non-oxidizing atmosphere, and the fibre may be submitted to tension in the carbonizing stage, suitably similar to or higher than that applied in the preheating or oxidative treatment. The value of tension to be applied is suitably derived from static tests effected using the apparatus of Fig. 1, in which a tow 1 is held under tension within electric furnace 14, the temperature of which is controlled by a thermostat operated by a thermocouple 17. Air or other gas used for oxygen permeation treatment is passed through the furnace, and as the temperature rises, scale readings are taken from which shrinkage and/or extension of the fibre can be measured. Further readings are taken using different weights in scale pan 7. A plot can then be made of per cent shrinkage/extension against time (Fig. 2, not reproduced), from which the ideal tension to be applied to the fibre during treatment is determined. Treatment may be in a number of stages, e.g. an initial stage under a certain tension followed by a period under higher tension to give a predetermined extension. Fig. 3 shows apparatus for the oxidative treatment and carbonization of a continuous supply of fibre. Fibre 21 is fed through oxidation furnace 23, which has three temperature zones T, T 2  and T 3  which may be maintained at 220‹ C., 210‹ C. and 220‹ C. respectively. Drive drum 27 applies tension to the fibre against the action of a brake (not shown), and air is passed through furnace 23 counter-current to the travel of the fibre, which next passes through carbonizing furnace 26 under a similar or higher tension applied by drive drum 28. Residence terms may be three-quarters of an hour in the oxidative treatment furnace followed by ten minutes in the carbonization furnace at 1000‹ C. Fibres so made show enhanced tensile strength and Young's modulus compared with conventional fibres.

In use the dredger travels on runners 74 over the water bed 75 so that a rejection sweep 76, which allows solid materials having a desired maximum size to pass through, and a collection sweep 79 which retains the solid materials having a desired minimum size which have passed through the rejection sweep and passes the desired sizes of solid materials to a gap between guide bars 92. The guide bars collect the guided solid materials and guide them to the ramp entrance. The solid materials are then moved up the ramp by the water flowing from the nozzle 95 and by the forward movement of the dredger. The water under pressure is provided by an electric motor 96 and a propeller 97. The solid materials pass from the ramp 94 to the hopper 103, the latter having an apertured cover 104 for diverting the desired sized solid materials downwards into the hopper and allowing pieces of solid materials smaller than the minimum desired size to escape. A flow of water from an entrance 105 passes through the trough and carries the solid materials falling from an exit in the hopper to the duct 107. The flow of water from the entrance 105 is induced by suction in riser conduit 108 or by an electrically driven propeller. The ramp 94 is held in an operative position against the bias of a spring 113 by an inflated bag 110. The ramp entrance may have sizing teeth and comb-rake projections for clearing the spaces between the teeth as the ramp is raised and lowered. Movement of the dredger over the bed 75 is aided by an over-rider 73 and by mounting the collection sweep 79 so that it is movable relative to the remainder of the device. A dorsal fin 117 may be provided to stabilize the dredger.
