Title: Process for the manufacture of salts of sulphuric acid esters of leuco vat dyestuffs of the anthraquinone series
IPC: C09B9/02
Filed: 1952-11-03
Abstract: Vat dyes are converted to their leucosulphuric esters by reacting with iron, cobalt, or nickel, with or without copper or brass, chlorsulphonic acid, and a mixture of a-picoline and diethyl - cyclohexylamine containing 10-60 per cent of the latter, followed by conversion of the esters to their water-soluble salts.  Features other than the choice of metals are the same as those of parent Specification.  The metals may be pre-activated, e.g. by treatment with the reactants other than the dye or by heating with glacial acetic acid.  Examples describe (1) the esterification of 1.5-dibenzoylamino -anthraquinone, using iron powder, alone or mixed with cobalt powder or brass powder, or Raney nickel, or cobalt powder, and (2) the esterification of 1.4-dibenzoylamino-anthraquinone or carbazolysed di-(51 - benzoylamino - 11 - anthraquinonyl) - 2. 8-diaminochrysene, using iron powder.

Title: Train control apparatus
IPC: B61L1/16
Filed: 1961-07-31
Abstract: 936,847. Recording passage of traffic. J. FRYBA. July 31, 1961, No. 27764/61. Class 105.  A railway traffic indicating system for recording the movement of a single axle or a closely adjacent group of axles of a rail vehicle over a control point comprises contactors I, II which are operated by the presence of an axle or group of axles on the overlapping rail sections 13, 14, respectively, to change over their associated contacts and, associated with each direction of traffic, e.g. left to right, a presence relay B, a slowrelease relay C and an indicating relay D which produces an output pulse of fixed duration after complete traverse of the control point by an axle or group of axles. The entry of axle 20 into portion 15-16 of the control point changes over contact I from position I 2  to I 3 and energizes relay B. Relay contact B 4  opens in the circuit of the presence relay E associated with the opposite direction of traffic, contact B 2  prepares a hold circuit for the B relay and a contact is switched from position B 5  to B 3  to prepare a circuit for operation of relay C. When the axle enters portion 16-17 contact II changes over from position II 2  to II 3  in which it completes the hold circuit for relay B. On entering portion 17-18 the axle changes contact I back to the I 2  position in which it energizes slow-release relay C. When the axle moves off the control point contact II changes back to the II 2  position, relay B releases and by changing over a contact from the B 3  position to the B 5  position de-energizes relay C and energizes relay D which provides an output indication signal during the slow-release period of relay C. To prevent the operation of relay B by a second axle or axle group interfering with the duration of the indicator signal, a hold contact D 2  maintains relay D energized via contact C 2  until relay C releases. In the arrangement a group of axles, e.g. axles 21 and 23, which are spaced apart a distance less than the length 15-18 of the control point act as a single actuating unit.

Title: Alternating current generator
IPC: H02K21/00
Filed: 1963-07-12
Abstract: 1,051,591. Dynamo-electric machines. L. R. POWER CORPORATION. July 12, 1963, No. 27769/63. Heading H2A. In a planar air-gap machine in which a stationary disc-shaped winding 8 lies between rotatable permanent or electro-magnets 6, 7, the output of the machine is adjusted by relative axial or angular movement of the magnets. This movement may be made manually, or automatically, or it may occur as a result of forces within the machine. One magnetic member may drive the other magnetically without mechanical connection (Fig. 3, not shown), adjustment being made by axial movement of one member. Alternatively, the axially movable member may be carried on a splined part of the shaft and controlled by electromagnetic or mechanical means. A screw thread on the driving shaft may be used to adjust the spacing in relation to the driving torque (Fig. 7, not shown). Similar methods are described for adjusting the angular relationship of the magnetic members (Figs. 9, 10, not shown) and this may occur naturally due to the machine torque under spring restraint (Fig. 11, not shown). Torsional oscillations are prevented by mechanical or electrical damping. The stator winding may include magnetic inserts. In excited machines, the field current may also be varied for control purposes.

Title: Improvements in or relating to the manufacture of anti-static fire-resistant belting
Inventor: WARREN FREDERICK WILLIAM
IPC: B65G15/54
Filed: 1956-09-15
Abstract: Antistatic and fire-resistant conveyer or transmission belting is made from fabric comprising yarns containing combustible cotton, rayon, nylon, or polyethylene terephthalate fibres or filaments associated in the weft and/or the warp with filaments of a flexible thermoplastic fire-resistant polymer or copolymer of vinyl chloride or vinylidene chloride, one or both sets of fibres or filaments being rendered antistatic by the incorporation of an antistatic agent, the noncombustible fibres or filaments being at least 15% by weight of the total, and the fabric being embedded in a resilient fire-resistant thermoplastic composition.  One or more plies of such fabric is or are embedded in similar fire-resistant thermoplastic material, and subjected to heat and pressure such that the fire-resistant yarns or components fuse and impregnate the remaining yarns or components.  The fabric may comprise yarns of mixed fire-resistant and other filaments or fibres, or yarns or threads of the two kinds associated by doubling, or such yarns woven together in the warp and/or weft. The fire-resistant components are rendered flexible by the incorporation of a solid or liquid plasticizer.  The antistatic material may be incorporated in both the fire-resistant components of the fabric and in the enveloping fire-resistant material, and may comprise acetylene black or other forms of conductive carbon, esters of polyethylene glycols having from 2-10(C2H4O) groups combined with one or more molecules of saturated or unsaturated fatty acids of 4-18 carbon atoms, for example polyethylene glycol mono-oleate or triethylene glycol dicaprylate, or tertiary amines or quaternary salts thereof containing at least one polyoxyalkylene group and at least one phenyl or substituted phenyl group which renders the compound oil-soluble, or for example the compound having the average composition (C17H33) N[(C2H4O)4,5H]2 or its quaternary salt with dimethyl sulphate.  A suitable fire-resistant antistatic composition comprises polyvinyl chloride, tritolyl phosphate, dioctylphthalate, stabilizer, conductive carbon black, antimony trioxide, zinc borate, boric acid, and natural rubber, the rubber being stated to give a product which can be milled and extruded without unduly affecting its antistatic properties.  The non fire-resistant components of the fabric may also be impregnated with solutions or dispersions of the above antistatic agents, or, in the case of plastic components, may have conductive carbon black incorporated in them during formation.  Specifications 741,738, 787,177 and 820,541 are referred to.
