Title: Improvements in electric control systems incorporating vacuum discharge tubes
IPC: G05B11/01
Filed: 1950-08-31
Abstract: 708,115. Valve relay circuits. KELVIN & HUGHES, Ltd., and GIBBS, A. Nov. 30, 1951 [Aug. 31, 1950], No. 21497/50. Class 40 (6). [Also in Group XXXV] Fig. 1 shows a control circuit in which the moving coils 14 of a measuring instrument connected to a pyrometer 15 control the position of a moving element 13 which determines the degree of coupling between the coils 11, 12 of an A.C. operated oscillator comprising valve 1. The resonant frequency of the tuned cathode circuit of the oscillator is also rhythmically varied between predetermined limits by variation of the capacitance of capacitor 2 and in one limiting position switch 3 also bridges its contacts to energize relay 4. Thus with element 13 in the position corresponding to the pyrometer recording a predetermined desired temperature, the change-over from oscillating to non-oscillating conditions of valve 1 is in step with the opening and closing of switch 3 so that relay 6, which is energized when valve 1 oscillates, and relay 4 also operate in step. The switches 7 and 5 are thus not against corresponding contacts at the same time so that neither of the field windings of the low voltage differential motor 8 is energized and the motor remains stationary. If the temperature of the furnace departs from the desired value the degree of coupling between coils 11 and 12 is altered by the changed position of member 13 so that the oscillatory and non- oscillatory periods of valve 1 are unequal in duration. Relays 4 and 6 thus operate for unequal periods and the motor 8 is rotated in one or other direction. A time lag may be introduced into the operation of relays 4 and 6. Safety precautions such as described in Specification 664,118, [Group XXXV], may be incorporated. In a further modification shown in Fig. 4 the moving coil 14 controls the degree of coupling between the coils of two oscillators 1A, 1B through the medium of movable members 13A, 13B. The two oscillators operate over different frequency ranges under the control of variable capacitors 2A and 2B and the current supply to the field windings of the differential motor (not shown) is controlled by relays 6A, 6B via switches 7A, 7B, so that movement of the temperature measured by pyrometer 15 from a predetermined value results in unequal energization of relays 6A, 6B and rotation of the differential motor in a given direction.

Title: Improvements in or relating to circular knitting machines
IPC: D04B9/06
Filed: 1923-08-25
Abstract: 203,326. Durand, E. H. M. E. Aug. 31, 1922, [Convention date]. Circular machines.-Relates to the provision of means whereby loops may be transferred directly from one needle b to an adjacent needle for fashioning or for other purposes. Latch needles having offset hook portions and recesses g<1> behind and below the latch pivots are operated' by means of a pattarn chain so that the hooks of certain needles such as a pass into the recesses g<1> of other needles b and receive their loops. The empty needles and the corresponding sinkers d are taken out of action. The adjacent sinkers have their thread drawing edges e at a lower level so as to cause the corresponding needles to draw the same amount of thread as the needles which went out of action. Narrowing is started at points on the tube diametrically opposed, by a pattern chain pressing a slide 10, Fig. 10, carrying a cam track, into the path of a projection 10<b> on a rocker 12. This rocker is pivoted to a bracket 15 on a rack ring 16. A pinion 17, gearing with the ring 16 and with another ring 18 carrying a bracket similar to 15, carries a starwheel 20 engaged by a projection 23 on the slide 10 which thus causes the brackets to approach under control of the pattern-chain. The first movement imparted to the rocker 12 lifts a rod 14 into engagement with a sinker jack h, the butt of the corresponding sinker d being thus transfered from the track x to the track x<1>. A second movement of the rocker 12, under control of the slide 10, depresses the butt of a needle jack f into the transfer track Y'. Each sinker d passes through a sley c, Figs. 4 and 6 the forked groove of which embraces the stems of a pair of needles a, b and when a sinker is drawn back for transfer purposes, its sley c brings the corresponding pair of needles into the same radial line. The needle a then removes the loop from the needle b. The butts of the empty needles and of the corrsponding sinkers d are retained to the tracks X<1> Y<1>. Specification 203,325 is referred to.

Aug. 23, 1945, No. 21656. [Class 104(iii)] [Also in Group XL] The overhead fittings of overhead electric traction systems are operated by current controlled, from the vehicle, by audiofrequency-current generated on the vehicle and transmitted inductively to the operating circuit as the vehicle passes a signal position. A primary coil L1, Fig. 1, carried by the head of the trolley arm 18, is connected to a motor-driven alternator MA and tuned by a capacitor C1. The secondary coil L2 is mounted on top of a support 16, preferably the support preceding the switches 7, 8, and is connected to amplifying and rectifying units including a relay LR which operates contacts LR1 to energise the solenoid actuating the switches 7, 8 as in Specification 546,311. The indicating lamps LPB, LPT are connected across the mains 1, 2 by switch contacts FC actuated by the conductor switch 7. The coil L2 may be mounted on support 17 in main 2 and coil L1 on arm 19. A . gas-discharge tube of the cold cathode type may be used in place of the amplifier-rectifier circuit, alternating current being used for the anode voltage 'to ensure that the tube will not remain ionised on completion of a signal. The switches 7, 8 may be restored by the mechanical or electromagnetic action of the collector, or a secondary coil may be supported on the branch and energised by the primary coil L1 after the trolley has passed the conductor switches 7, 8. The vehicle circuit, Fig. 5, comprises a series-wound motor with field MS connected to a battery E by a switch A1 operated by' a relay A connected in series with a push-button S across the battery E. The alternator AA generates current of about 1500 cycles per second through the tuning capacitor C1 and the transmitting coil L1. The amplifier-rectifier circuit contains a receiving coil L2 tuned by the capacitor C2 and connected to the grid of a valve VA between the conductors 1, 2 or feeders 53, 54. The anode of valve VA is coupled by a transformer TRA with the grid of a rectifier valve VB whose anode is connected to the coil of relay LR. The indirectly-heated cathodes of VA, VB connect to grid-bias resistors YA, YB and parallel capacitors C3, C4. The supply is stabilised by coldcathode gas diode tubes NTA, NTB with resistors YD, YE and tungsten-filament lamps LPA. The switches 7, 8 are re-set mechanically by the collector or alternatively by a second solenoid energised from the coil. L1, and a modified circuit is shown for this purpose.

Patent GB-482104-A (GB)
Title: Improvements in or relating to the manufacture of thin walled tubes, shells and the like
IPC: H01H1/02
Filed: 1936-11-03
Abstract: In moulding thin-walled tubes, shells or plates of non-ductile, refractory material by applying to a core a thin layer of a paste of the refractory material with a binder, heating until the layer is rigid, and removing the core, the binder is a synthetic resin dissolved in a non-aqueous solvent.  The binder may be a synthetic resin varnish such as those known under the Registered Trade Marks "Glyptal" or "Bakelite."  After removing the core, as by heating, the rigid material may be heated further as for sintering.  The refractory material may be a metal such as tungsten, chromium or iridium, or a metal oxide such as alumina or zirconia or a mixture of zirconia and thoria, or a refractory carbide.  The oxide may be generated on heating in oxygen where the metal is incorporated in the paste.  The core may be wound with a fine wire of a refractory metal such as molybdenum before, during or after applying the paste layer and so as to act as a reinforcement.  The core may be a paper tube or a solid carbon rod and is removed by heating.  The paper may be blotting paper and may be formed by wrapping around a rod, pasting the edges and securing with thread.  If the temperature required is not too high, the core may be a glass tube coated with wax.  The tubes or plates may be used for resistors or condenser dielectrics. According to the Provisional Specification, the binder may be starch or other aqueous solution, the tubes may be used as inner sheaths in high-pressure, metal-vapour lamps, and Specification 477,105 is therein referred to.
