Title: Improvements in or relating to systems for varying the energisation of electric circuits
IPC: G05B11/01
Filed: 1944-01-24
Abstract: 580,044. Control of motors. IGRANIC ELECTRIC CO., Ltd., BEDFORD, J. M., FIELD, J. A., and MAYNARD, S. P. Jan. 24, 1944, No. 1344. [Class 38 (iii)] [Also in Group XXXV] Travelling to predetermined limits. In a system for varying the anode current of an electronic valve in accordance with the position of a movable element, an alternating voltage which is inductively varied in accordance with the position of the movable element is applied, in opposition to a second alternating voltage which is independent of variations of the first alternating voltage, to the control electrode of the electronic valve. A magnetic core 1 which may be attached to a float, lift, train, machine tool or other body to move in the direction shown varies the coupling between coils 5 and 6, Coil 5 is supplied with A.C. of fixed voltage from a mains transformer 9 and the variable voltage induced in coil 6 is applied, in opposition to a manually adjustable A.C. voltage, obtained from transformer 9 through potentiometer 12 across the primary of a transformer 11, the secondary of which is connected between grid and cathode of a pentode amplifier valve 4 in series with D.C. bias obtained from a rectifier 10. A D.C. relay 2, fed through a matching transformer 3 and a rectifier 7 from the anode circuit of the pentode. is thus energised in accordance with the position of core 1 and operates at well-defined positions of the core on either side of the maximum coupling position. With an A.C. relay, rectifier 7 is dispensed with. Application of the invention as a limit switch is referred to.

Title: Device on raschel looms for the production of pattern stripes running zig-zag in the fabric
IPC: D04B27/26
Filed: 1936-01-20
Abstract: 453,324. Knitting-machines. GLUCK, M., and DALLOS, M., 6, Rudolf-tÚr, Budapest. Jan. 20, 1936, No. 1783. [Class 74 (ii)] To produce diagonal or zigzag pattern stripes on Raschel looms, the bar 5 carrying the eyed guiders for the pattern threads carries an internallythreaded sleeve 6 engaged by a threaded spindle 7 supported by a bearing 9 mounted in grooves in a guide 10, which is oscillated to form the mesh. The spindle 7 is oscillated by a pattern-chain controlled carriage 15 and a spring, the patterns extending in the direction of knitting that would otherwise be produced being converted into diagonal patterns by imparting an additional stepwise displacement to the bar 5. For this purpose a bevel wheel 11 on the spindle meshes with a bevel wheel 12 connected to ratchet wheels 13, 14, which can be driven in opposite directions by pawls 18, 19 on a carrier 17, which is oscillated by a spring and a pattern - chain controlled carriage 21. The two pawls are caused to operate alternately, for example, by means of a manuallyoperated reverse lever which is operated to disengage one of the pawls, and allow the second pawl to act for a determined time, after which it is operated to cause reversal. Instead of using a spindle, the ratchet mechanism may be connected to a pinion acting on a rack on the bar 5.

Title: Process for the dressing of leather
IPC: C14C11/00
Filed: 1955-01-20
Abstract: An aqueous emulsion comprising a copolymer of butadiene and acrylonitrile in which the molecular weight of the copolymer has been kept so low by the addition of a chain terminating agent that when isolated the copolymer has an oily-viscous consistency such that its hardness cannot be measured with a Defo measuring instrument, is used for dressing leather.  Optionally a third vinyl component, e.g. styrene, substituted styrenes, acrylic ester, methacrylic ester and asym. dichloroethene may be present. If desired the emulsion may be mixed with emulsions of Defo hardness of e.g. 6000.  The emulsion should preferably contain not more than 50 per cent by weight of acrylonitrile.  In the example, a leather is treated with an aqueous liquor comprising a casein-based coating dye, a viscous-oily butadiene-acrylonitrile copolymer and an aniline dyestuff followed by an aqueous liquor comprising in addition to these components a butadiene-acrylonitrile copolymer and an ammonia-saponified casein solution.  The butadiene-acrylonitrile copolymer used was prepared by emulsifying 60 parts of butadiene and 40 parts of acrylonitrile containing 6 parts of di-isopropyl xanthic disulphide as chain terminating agent in an aqueous solution of the sodium salts of the sulphonic acids of long-chain paraffins, sodium hydroxide, sodium pyrophosphate and potassium persulphate. Triethanolamine is added to activate the mixture and polymerization at 40 DEG  C. carried out until 80 per cent of the monomers had reacted. Di-tert.-butyl-1.5-p-cresol is added to stabilize the emulsion.  A specified mixture comprising butadiene, acrylonitrile, styrene and dodecyl mercaptan can be similarly emulsified and polymerized. Specifications 633,631, [Group VIII], and 678,614 are referred to.

Abstract: 896,889. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Jan. 15, 1960 [Jan. 20, 1959], No. 2088/59. Class 39(4). A method of testing for the presence of a damaged fuel cartridge in a gas-cooled nuclear reactor comprises sampling coolant gas which has passed over the fuel, passing the sample gas over a surface which is under the influence of an electric field so that solid daughter products of long-lived fission products are precipitated on the surface, and monitoring the surface to detect beta particles and gamma rays of energies greater than 3 Mev. The sample gas may be retarded for about three minutes in a labyrinth device to allow decay of most induced activity in the coolant and of short lived fission products so that the main daughter product detected is rubidium 88. A filter may be incorporated in each sampling duct for preventing solid contaminants from passing to the precipitation chamber. Preferably one gas sampling pipe is provided from each channel and incorporates a three-way valve whose normal position connects the channel to two sampling ducts arranged in a cross matrix and whose alternative position connects the channel with another sampling duct connected to a monitor and employed for continuous monitoring of a single channel only. The monitor may comprise a precipitation chamber closed except for a gas inlet and outlet and containing a phosphor contained in a charged thin cylindrical metal electrode, an end of the phosphor being exposed to a photo-multiplier tube the output of which is passed to a discriminator which excludes most of the counts due to particles of energy less than 3 Mev.

Abstract: In the purification of sulphur as described in the parent Specification, sulphur dioxide formed during the process is removed by treating the solution with calcium oxide which has been slightly moistened as by treatment with wet steam or by sprinkling with water, the amount added being small, e.g. two per cent. Alternatively, the necessary water may be added to the sulphur solution.  Addition of this amount of water does not affect the physical nature of the lime which may be used in granular condition as a filter bed for the solution of sulphur.
