Patent GB-455804-A (GB)
Title: Improvements in or relating to processes for de-sizing
IPC: D06L1/14
Filed: 1935-06-20
Abstract: Goods sized with starch are de-sized with amylase preparations containing high molecular organic basic compounds containing one or more organic residues of at least eight carbon atoms, or salts thereof, if desired together with other activators, stabilizers and substances exerting a buffer action.  Preferred compounds are sulphonium compounds and compounds containing one or more aliphatic or cycloaliphatic chains of 10--20 carbon atoms.  The compounds may be substituted by alkyl-, aryl-, aralkyl-, oxy-aminogroups, or halogens, and are preferably employed in the form of their salts.  An addition of 1 part of the compound to 2,000--20,000 is preferred.  In examples: (1) To 1,000 litres of water at 48 DEG  C. are added 1 kg. of common salt, 200 gms. of dodecylbenzyl-methylsulphonium-methyl-sulphate and pancreas amylase corresponding to 1,000 amylase units; the pH value is adjusted to 6,8; the bath readily de-sizes starched cotton goods; (2) same as example 1, but the compound used is 150 gms. of hexadecyldiethylsulphonium-methyl-sulphate; (3) same as example 1, but the compound employed is 70 gms. of triphenyl-dodecylsulphonium-bromide.  Other sulphonium and also arsonium compounds are mentioned.

Abstract: 1,077,096. Welder's masks. C. VAJTUONE. April 29, 1965 [May 4, 1964], No. 18056/65. Heading G2J. [Also in Division H2] A welder's mask adapted to be fitted on the head comprises a blackened glass plate 2 which is rotatable between an operative position (shown in full lines in Fig. 3) and an inoperative position (shown in broken lines), the movement of the plate being effected by means of an electric motor when the welder blows on a vane 34 to complete a circuit containing the motor. The plate 2 is pivoted about its horizontal centre line and in its two extreme positions abuts against a pair of flaps 9 secured to the frame of the mask. The vane 34 is pendulously supported within the casing 13 of the electric motor and switch mechanism and so returns to its initial position after actuation. The switch mechanism (see Division H2) is constructed so that actuation of the vane will move the plate from either position.

Title: Improvements relating to magnetic discriminators
IPC: G05B11/01
Filed: 1952-07-17
Abstract: 731,059. Magnetic amplifiers. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and KING, K. G. June 24, 1953 [July 17, 1952], No. 18086/52. Class 40 (4). [Also in Group XXXV] A variable inductor comprises an A.C. winding wound, to prevent coupling with the D.C. windings, in two series connected halves 10, 11 on the central limb, split into two halves 2, 3 of a magnetic core, which has two outer limbs 1, 4 carrying D.C. windings 9, 12 connected in series as shown, or alternatively in parallel. Limb 1 is of a saturable magnetic material such as that sold under the Registered Trade Mark " Mumetal," which saturates before the rest of the core, and has a # I curve such as 8 in Fig. 2, while limb 4, which has an airgap 7, has a linear # I relationship 22. When the D.C. through windings 9, 12 has the value corresponding to the common point of curves 8, 22, the flux in limbs 1 and 4 is equal and none passes through the central limb. When the D.C. varies in either direction from this value, the two fluxes differ by an amount which passes through the central limb and varies the inductance of windings 10, 11. Fig. 1 shows a circuit for stabilizing the voltage across load 21 supplied from rectifier 19 in which the departure of the load voltage from the required value varies the inductance of windings 10, 11, which are energized from an A.C. supply, and the consequent change in current through these windings is used, through amplifier 18 to control the rectifier in such a way as to restore the load voltage to the desired value. This value may be such as to produce current i, Fig. 2, in the windings 9, 12 differing from the value corresponding to the intersection point of curves 8, 22, to allow for discrimination between decrease and increase from the required value. Specification 730,080, [Group XL (b)], is referred to.

[Class 122 (iii).] To reduce the capital expenditure on electric cables and transformers, the energy to supply peak loads is transmitted from a power station or stations to a heat accumulator plant near the peakload consumers as heat, the base load being supplied directly as electric current through cables ; the stored heat is used as required by an electric generator in the peak load station. Steam, hot water or other heat conveying medium would be continuously transmitted at an average rate or the accumulator may be charged during the night. A power generator may be interposed between the steam generators in the main station and the long distance pipe line to the accumulator plant. The condensate from the peak load generator may be led back to the boilers, a water vessel being arranged between the condenser and the return pipe. A reserve boiler may be installed at the peak load station. Specification 217,952, [Class 122 (iii), Steam engines, Kinds &c.], is referred to.

Abstract: 145,797. Tober, C. March 16, 1918, [Convention date]. Braiding-machines.-Inner bobbins 20 carried on slides 37 are driven round by the roller system described in Specification 29659/09 on a track 41 of a slotted body 24 which rotates with the outer bobbins 18, instead of being a fixture as hereto. fore. By arranging the slides 37, as shown, so that they are situated between the braiding axis and the bobbins 20, the driving pressure between the rollers 30, 23 can be considerably reduced. The rollers 30 are mounted on spring arms 28 which press their hubs 32 against a stationary race 33, but the friction drive may be replaced by toothed gearing, in which case the arms 28 are dispensed with.

Title: Improvements in or relating to the manufacture of luminescent screens
IPC: H01J9/22
Filed: 1952-07-23
Abstract: 742,987. Luminescent materials. GENERAL ELECTRIC CO., Ltd., HILL, R. T., and SAUNDERS, E. F. July 23, 1953 [July 23, 1952], No. 18657/52. Class 39 (1). [Also in Group XXIII] A method of manufacturing a luminescent screen of a C.R.T. includes the steps of depositing upon a glass supporting surface from suspension in a liquid medium a layer consisting of a mixture of a powdered luminescent material and a powdered glass of melting point lower than that of the glass of the supporting surface, the proportion of powdered glass in the mixture being from 10 to 50 per cent of the volume of the mixture, drying the layer, and heating the layer and supporting surface, e.g. to 450‹ to 500‹ C., so as to cause the powdered glass to fuse and bond the luminescent powder firmly to the supporting surface. The supporting surface can be formed of a lead or a soda glass and the powdered glass can be a lead borate glass composed of 80 parts PbO, 20 parts B 2 O 3  and 2.5 parts ZnO, by weight, the softening temperature being about 300‹ C. and the coefficient of thermal expansion 9.6 x 10<SP>-6</SP>. The coefficients of thermal expansion of the two glasses are suitably matched. The particle size of the powdered glass can be of the same order as that of the luminescent powder and the amount of the powdered glass sufficiently large, e.g. 20 or 25 per cent by volume, to cause the whole of the luminescent powder to be embedded therein after the fusion step, so that the free surface of the resultant layer is substantially smooth. A continuous metallic layer, e.g. of aluminium, can be formed upon the layer of fused glass and luminescent material, e.g. by a lacquering process. The luminescent material can be zinc orthosilicate in a solution of nitro-cellulose in butyl acetate. It is stated that the refractive index of the lead borate glass is of the same order as that of the luminescent material thus producing a reduction in the internal reflection of light. Specifications 512,308, [Group XXIII], and 559,573 are referred to.
