Title: Method and means for manufacturing refractory slabs
IPC: B28B3/24
Filed: 1974-11-22
Abstract: 1474713 Extruding refractory fibres T BRAATEN 22 Nov 1974 50784/74 Heading B5A Refractory slabs, for use in foundries as refractory parts in conduits and moulds for molten metals, are produced by simultaneously extruding and dewatering an aqueous slurry of fibres and binding agent, the extrusion being effected by means of a reciprocating plunger 6 which forces the slurry through a transversely elongate passage 4, and the dewatering being effected by the compaction applied by the plunger 6, in combination with vacuum applied from a chamber 13, through a foraminous screen 12 at the passage entrance. The action of the plunger also avoids a preferential fibre orientation in the slab. The plunger 6, which is reciprocated from an eccentric by a connecting rod 9, is of a shape and size corresponding to that of the passage 4, and is mounted by bolts 15 for replacement to correspond with different passages 4. The slurry is fed through an extruder opening 11, into a chamber 10 in which it is agitated, during reciprocation of the plunger, by spare section tubular members 16 carried with the plunger and extending along its sides corresponding to the transverse elongate dimension of the passage 4.

Filed: 1963-12-24
Abstract: 1,006,736. Cooling gases by direct contact with liquids. TITANGESELLSCHAFT. Dec. 24, 1963 [Dec. 24, 1962], No. 50868/63. Heading F4K. Hot titanium-dioxide-containing gases are cooled by so passing them with a linear speed of not more than 0À5 metres per second through a tube 1 on whose inner wall surface is maintained a film of water, that the temperature of the water film does not rise above 40 C. during the cooling operation. Preferably the water enters the tube through tangential inlets 6 so giving the water a rotary movement. Another form described uses a tapered tube 7 (Fig. 3) the upper end of which is formed with a spillway 8 in which the water is given a rotary movement by tangential inlets 3. The water overflows the spillway and covers the inner surface of the tube 7 with a uniformly thin film. The temperature of the hot gases before they enter the tube to be cooled, may be reduced by mixing them with a cold gas such as air, chlorine or recycled waste gas.

Abstract: 1385189 Measuring angles electrically M K RUSSELL and A W RUSSELL 18 Oct 1972 [5 Nov 1971] 51625/71 Heading G1N A sensor for measuring the orientation of the head of a drilling tool comprises a housing 2 in which a cylindrical brass member 1 is disposed on a bearing ball 9 and pin 6 whereby a disc 3 carried by the member rolls on the inner face of the housing to the lowermost point in its circular path under the action of gravity, the member 1 carrying a bar magnet 10 which acts to change the flux in four fixed sensing coils 13, 14 (17, 18) Fig. 2 (not shown), which coils have saturable magnetic cores and are arranged in two perpendicular planes, and the coils being connected into two fluxgate circuits Fig. 4 (not shown). The coils are connected across an A.C. source (S1). Because the cores are saturable, flux imbalance produces a second harmonic voltage which is amplified and synchronously demodulated to produce an output voltage (Vx) which produces a feedback current through resistors (R 1 , R 2 , R 3 ) to the junction of the coils and the current produces a field which restores the flux balance. Hence the output voltage (Vx) is a measure of displacement x of the magnet with respect to the coils. Similarly displacement y is measured in a duplicate circuit connected to coils 17, 18.

Abstract: 1382412 Thermonuclear fusion apparatus UNITED KINGDOM ATOMIC ENERGY AUTHORITY 28 Jan 1972 [4 Nov 1970] 52561/70 Heading G6P In operation of a plasma confinement system which comprises a toroidal vessel (11) (Fig. 1, not shown), means for generating a magnetic field extending around the torus parallel with its minor axis, and means for generating a rotational transform of the magnetic field, the variable parameters are chosen to achieve, as a consequence of diffusion of plasma out of the confinement region, a plasma current around the torus which provides an additional rotational transform which is a substantial proportion of the total rotational transform. The rotational transform, or poloidal field, effects system stabilization. The poloidal field arising from the plasma current may be 90% or more of the total poloidal field. The system has means (15) for injecting plasma or plasma-forming material. The latter may be pellets of solidified hydrogen or deuterium which produce in the system a " seed " current to provide the externally produced rotational transform. Alternatively, the " seed " current may be replaced by an externally produced rotational transform, such as in a stellarator, or by a travelling electromagnetic wave system. In order to produce the plasma current, the variable parameters are chosen so as to satisfy the two equations  where: I # rB<SP>0</SP>/ 2  which is the total current within radius r and parallel with B # ; Be = (H)B # , the poloidal magnetic field components; B #  = B<SP>0</SP>/ h , the toroidal magnetic field components parallel with the rim or axis of the torus; r is the minor radial co-ordinate of the torus; R is the major radius of the torus; kT is the effective plasma temperature; n is the plasma density; S(r) is the total "source" of plasma within the minor radius r;  #  is the plasma electrical resistivity. (B #  is generated by solenoid windings upon the torus.)

Filed: 1966-11-28
Abstract: 1,192,378. Respiratory apparatus. G. B. BURCHELL 'and R. W. V. MOREL. 28 Nov., 1967 [28 Nov., 1966], No. 53251/66. Heading A5T. [Also in Division F2] Respiration apparatus comprises a supply 30 of gas at a high positive pressure connected to a means 21, 22 which is arranged to emit the high pressure gas intermittently, there being a valve device (Figure 1) connected to the means and serving to reduce the gas from the high positive pressure to a low positive pressure, and a conduit connected downstream of the valve device for leading the low pressure 'gas towards a patient or towards a space between a breathing bag and a casing surrounding the bag. As shown in Figure 4, the high pressure gas supply 30 is connected through a double acting piston valve 31 and an adjustable throttle 33 to the inlet 2 (Figure 1) of a pressure reducing valve device i having an outlet 9 leading towards the patient. The apparatus also includes spring loaded relay valves 36, 38 connected to gas supply points 37, 39, to reservoirs; 35, 40, and to 'the control chambers of the piston valve 31. In operation, gas is supplied to the patient through conduit 32 " until 'suffifficient pressure has built up in the reservoir 35 to 'operate the valve 36 to produce a change-over of the valve 31 allowing the patient to exhale. Subsequently the pressure in the reservoir 40 increases so that the valve 38 operates to charge-over the valve 31 and the patient reverts to forced inhalation. In an alternative embodiment the apparatus comprises (Figure 3, not shown) the gas supply (20) connected through an adjustable throttle (21) and a reservoir (22) 'to the valve device (which may be in one housing with the reservoir), the gas being arranged to pass into the reservoir more slowly than it leaves so that due to the action of the valve device an intermittent flow results. Further 'embodiments (Figures 5, 6, and 7, not shown) also comprise valves which interrupt the supply to the patient according as reservoirs connected to the valves fill and empty.

Title: Improvements in reed switch circuits
IPC: H03K23/74
Filed: 1965-12-20
Abstract: 1,127,634. Counters; data-processing. GENERAL ELECTRIC CO. 20 Dec., 1965 [30 Dec., 1964], No. 53792/65. Headings G4A and G4D. Double-throw reed switches are used in shift registers and counters. In the shift register of Fig. 1 the input to coil 7 or 9 is marked according to the information to be entered. Switch 27 oscillates between contacts 29 and 31 so that coil 7 (or 9) energizes to position contact 1 in the first stage, after which coil 17 (or 19) energizes to position contact 11. The next oscillation of switch 27 shifts the information to the next stage, and so on. The register may energize output loads 37. Read-out may be effected by half-cycles of A.C. from transformer 43 applied to lamps 39. The shift register may be reversible (Fig. 2, not shown) or may be duplicated with separate inputs but simultaneous shift (Fig. 3, not shown). Alternatively the register may comprise an upper steering channel and a lower data storage channel, Fig. 4, in which data is stacked up in the stages backwards from the output. An output release limit switch 143, when actuated, allows data to be shifted towards and from the output. A control relay 129 in each stage can divert information to a read-out 139. Ring counter. The shift register of Fig. 1 can be modified (Fig. 5, not shown) so that only one stage registers 1, thus forming a ring counter. A reset switch restores all stages except that representing zero. The counter may be modified to form a reversible counter (Fig. 8, not shown). Flip-flop and cascade counter. By arranging two reed-switches A, B, Fig. 6, in cross-connected fashion successive movements of a switch 147 reverses first A and then B, so changing over from an output on 153 to one on 155. This circuit thus divides by two and a succession of such circuits forms a cascade counter (Fig. 7, not shown).

Abstract: 1,169,190. Boreing machines. FOSDICK MACHINE TOOL CO. 1 Dec., 1966, No. 53921/66. Heading B3C. [Also in Division F2] A variable-speed transmission for rotating the spindle 6 of a jig borer comprises an expanding pulley gearing followed by a planetary gearing which gives a low ratio or direct drive. The expanding pulley gearing comprises a driving pulley 30 driven by an electric motor 28 and having a fixed flange 66 and an axially movable flange 67 which is connected through a bearing to a sleeve 80 which is in screw-threaded connection with a shaft 87 which can be reversibly rotated by an electric motor 48 to adjust the pulley diameter. A driven pulley has a spring biased axially slidable flange 70, The output shaft 32 of the pulley gearing is connected by a toothed belt 50 to an input shaft 51 of the planetary gearing. The planetary gearing has input and output suns meshing stepped planets in a carrier 140 which can be clutched to the input shaft 51 by an electromagnetically controlled friction clutch 168 to give direct drive from the input shaft 51 to an output gear 53, and which can be stationed by an electromagnetically controlled brake 170 for low ratio drive. The output gear can be stationed by an electromagnetically controlled brake 171 to station the jig borer spindle. The brake 171 and the low ratio brake 170 can be momentarily engaged alternately to jog the spindle. The electric motor 48 of the pulley gearing and the clutch and brakes of the planetary gearing may be controlled by separate manual controls, alternatively the transmission may be regulated automatically under tape control. Indicating output speed.-A tachometer generator 37 is driven by the output shaft 32 of the pulley gearing and energizes a tachometer having two sets of calibrations corresponding to the direct drive and low ratio settings of the planetary gearing. Spindle feed.-The output gear 53 of the planetary gearing drives a spindle sleeve 52 which rotates the spindle at the desired speed by way of a splined spindle drive shaft 15. The spindle 6 is journalled within a non-rotatable quill 5 which is shiftable vertically with respect to the drill head 3 at a selected feed rate to advance the spindle with respect to the workpiece 10. The sleeve 52 is also connected, by a tooth belt 55, to the input shaft of a changespeed gear for the spindle feed transmission. Feed motion is thus transmitted to the spindle at a selected rate which is related to the selected spindle speed. Rapid advance and retract is provided by rapid traverse motor 45, energization of which disengages the clutches of the spindle feed change-speed gearing.
