Abstract: 377,184. Prepayment mechanism for meters. ALDER & MACKAY, Ltd. and ANDERSON, J., New Grange Works, Stewart Terrace, Edinburgh. April 15, 1931, No. 11202. [Class 27.] Coin action, thrust and multiple-coin.-In prepayment mechanism, particularly for gas meters, which may be adjusted to take coins of two or more different diameters, the coin inserted into a coin holder a, Figs. 1 and 2, between cheeks c, d depresses a plate e against the action of a spring i so that a tooth f thereon engages and drives a quantity wheel g, when the coin-holder is rotated. A large coin, for example a penny, acts against a member n secured to the plate e When set to take a small coin, for example a shilling, the coin acts against the end p of a lever o which is pivoted to the member n and is pulled by a spring f into position to form the base of the coinholder. When pennies are being used the lever o is held out of action by a claw r on a sleeve s slidably mounted in a central part of the coinholder casting. To adjust the mechanism for shillings, the front plate with the coin-holder is removed and the sleeve s is pulled out, rotated and pushed back till the claw r is locked in the short arm of a bayonet joint slot z, as shown in Fig. 5. On replacing the coinholder assembly, the sleeve s fits over a tube t and causes a change in the gearing between the measuring-out mechanism and the meter-driven spindle.

Filed: 1975-03-18
Abstract: 1485194 Olefin-tertiary alcohol telomers DART INDUSTRIES Inc 18 March 1975 [20 March 1974] 11235/75 Heading C3P [Also in Division C2] A low molecular weight tertiary alcohol telomer at least 60% by weight of which boils at less than 245 C. at 0À5 mm. Hg is prepared by reacting a secondary alcohol telogen wherein R 1  and R 2  each independently represent C 1 -C 8  alkyl or phenyl or together represent an alkylene group, with a monoolefinically unsaturated hydrocarbon taxogen H 2 C=CHR wherein R represents a hydrogen atom or a C 1 -C 8  alkyl or phenyl group, in the presence of a catalytically effective amount of a free radical generating initiator in a reaction zone, the telogen : taxogen ratio in the reaction zone being greater than 1 : 1, at a temperature of 125-275 C. and a pressure of 2000- 10,000 p.s.i.g. The initiator is for example a peroxide, an azo compound or oxygen; an activator may also be present, e.g. a ferrous salt, an amine, a mercaptan or cobalt naphthenate. The reaction is preferably conducted semi-continuously, the initiator being added in a number of doses, or continuously. The telomers contain generally 10-12 taxogen units per telogen unit. In examples the telogen is isopropanol or cyclohexanol and the taxogen is ethylene; with isopropanol the average molecular weight was 228-350 and with cyclohexanol it was 257. The tertiary alcohol terminal group of the telomer may be oxidized, e.g. with nitric acid /ammonium vanadate, to a terminal carboxylic acid group; the tertiary alcohol terminal group may also be dehydrated to provide terminal unsaturation.

Patent GB-964450-A (GB)
Title: Encoding device for the electro-optical scanning of characters
Inventor: KING GORDON VAN BEUREN
IPC: G06V10/24
Filed: 1962-03-27
Abstract: 964, 450. Automatic character reading. SPERRY RAND CORPORATION. March 27, 1962, No. 11686/62. Heading G4R. [Also in Division H4] In a character reading apparatus the character is scanned by a cathode ray tube in a contracting spiral, the deflection control circuit being responsive to the signals derived from the scan to centre the spiral on the character. The cathode ray tube in Fig. 1 consists of a flying spot scanner, reflected light being received by two photo-multiplier tubes V5, V6 connected in parallel. Alternatively a camera tube may be used. The spiral pattern of fifteen turns is generated by a linearly damped sine-wave of fifteen cycles, recorded on a magnetic drum. This is applied at T1, Fig. 3 to a phase-splitting circuit to generate X and Y control signals at 90 degrees phase displacement. Normally the control signals are applied through valves V1 and V2 to the plates of the tube 1. When a character comes into the scanning field, the photocells V5, V6 give a "black" signal which, after clipping and smoothing is applied via terminal T7 to both valves V3 in the X and Y control circuits. The black signals each serve to cause the X and Y signals present at that instant to be applied to the integrating circuits C7, R3 and the integrated signal is applied as a D.C. bias to the deflection plates. When a character is cut by a scan, the centre of the spiral therefore moves in a radial direction towards the intersected part of the character by an amount proportional to the diameter of the spiral at the instant of intersection. This movement causes the scan to move to the edge of the black but it will probably cut it again on the next turn. The centre then moves again in the same way until the scan cuts the character symmetrically top and bottom, or right and left. The spiral is then properly centred on the character and the succeeding turns of the spiral scan the character from the outside to the centre giving signals for the identification of the character. During this process the centre of the spiral remains stationary or substantially stationary, the integrating circuits receiving oppositely poled signals from opposite sides of the character which cancel each other. The time constants are high enough to prevent oscillation of the centre. The apparatus may be designed for characters which are white on a black background or for characters on transparent film.

Title: Improvements in or relating to the production of zirconia
IPC: C01G25/02
Filed: 1941-09-12
Abstract: 550,288. Zirconium oxide. AXT, M. O., and BERK & CO., Ltd., F. W. Sept. 12, 1941, No. 11720. [Class 1 (iii)] Zirconia is produced by a process in which a solution of zirconium sulphate, free from acid and from alkali salts which form double compounds with zirconium sulphate, and in the absence of a large proportion of magnesium sulphate, is hydrolysed in the presence of between 30 and 35 per cent. of calcium chloride (containing about 75 per cent. CaCl 2 ) and the precipitate calcined. Part of the calcium chloride may be replaced by an equivalent amount of calcium nitrate; if the zirconium sulphate solution contains calcium sulphate the amount of added calcium chloride is correspondingly reduced; when the solution contains iron this is reduced before the hydrolysis. Specification 544,965 is referred to.

Abstract: 252,364. Baur. W. May 20, 1925, [Convention date]. Japanning; varnishes.-Stationary structures such as bridges, or difficulty movable objects of iron, wood, &c. are coated by applying to them a refractory varnish or paint and burning it in by a movable hot air blast or the like by heating it from 50 to 600‹ C. A suitable coating material may be made from ester gums with castor oil and metal oxide driers, and a pigment or filler of metal powder. In an example castor oil is heated with 5-10 per cent of metal oxides, such as those of lead, zinc, or cobalt. The cooled product is soluble in solvents such as turpentine. benzine, or benzol, and can be mixed with varnish constituents such as ester gum, drying oils, metal powders, &c. The burning in may be effected by hot air blast, or by a blast similar to a brazier's lamp, but in which the flame does not contact with the work or pressure jet apparatus or a spraying pistol. The work is rendered moisture free by hot air before coating. The Specification as open to inspection under Sect. 91 (3 (a) describes the temperature of burning in as 600‹ C. or over. This subject-matter does not appear in the Specification as accepted.
