Feb. 16, 1935, Nos. 5109 and 7520. [Class 27] Price-changing mechanism.-In prepayment meters of the kind provided with means for locking the prepayment transmission train, when this train is broken for adjustment of the price-changing portion, a wheel g of a spring- driven train, which is connected to a wheel e through a price-change set of gears including a wheel c meshing with the wheel e and a changewheel f meshing with the wheel g, is locked, when the price-change portion is removed for adjustment, by a braking portion k on one arm m of a lever controlled by a spring n. The price-change portion is located on the meter frame a by a boss b entering a hole in the frame, and is secured in position by a nut h on a screw i which enters a curved slot j. A plate r is pivoted on the price-change portion and secured in adjusted position by a nut t on a screw passing through a curved slot in the plate r. A pawl u on this plate engages the end o of the other arm of the lever m, when the price-change portion is in position, and holds the brake k out of engagement with the wheel g. The end o is located between jaws p on a fixed plate q, these jaws preventing accidental movement of the lever m when the pricechange gear is being removed or replaced. The upper jaw p enters a slot w in the part u and guides the plate r into its proper position. The plate r is adjusted, according to the size of the wheel f, so that, when the part u meets the portion p<1> of the plate q between the jaws p, it ensures that the teeth of the wheels f, are engaged to the correct depth.

Patent GB-1379231-A (GB)
Title: Method of growing crystals
IPC: C30B7/00
Filed: 1972-03-22
Abstract: 1379231 Growing crystals B A SECURITY SYSTEMS Ltd 22 March 1972 [24 Feb 1971] 5288/71 Heading B1G A crystal is grown by immersing a seed crystal in a saturated or near-saturated solution of the crystalline substance and maintaining the solution super-saturated by an amount such that the rate of growth of the crystal is below the optical growth rate, i.e. the rate at and above which defects arise in the crystal due to over-rapid growth. Super-saturation may be maintained by lowering the temperature or by evaporating off solvent. The weight of the substance deposited is preferably effected by (a) determining the surface area of the crystal (b) calculating the weight of substance to be deposited from solution over area (a) in a given time and (c) maintaing the solution supersaturated by such an amount that it will deposit weight (b) at a rate below the critical growth rate. In carrying out the method the crystal is mounted in a support wherein only one or a number of faces of the seed crystal may be exposed to the supersaturated solution, e.g. a major face which is a natural crystal facet. A suitable apparatus for carrying out the method is shown in the figure wherein vessel 1 contains saturated solution 2, and each seed crystal is mounted on a plate 3 positioned on an arm of a stirrer 4 driven by a motor 4' and a gearbox 5' at about 30 to 80 r.p.m. A rotating seal 7' is provided in lid 7 for stirrer 4 and the vessel 1 is surrounded by a jacket 5 which contains a heater 9 which controls the temperature of solution 2 by varying the air temperature in the space betwene 5 and 1. The crystals grown may be triglycine sulphate, or deuterated triglycine sulphate. The crystals may be used in infra-red radiation emission burglar alarms.

In a process for making reinforced elastomeric belting in which the edges of the belt are shaped during vulcanization by edge tapes 12, the tapes are stripped from the vulcanized belt, for re-use and transported away in a direction opposite to that in which the belt is travelling. In the embodiment illustrated in the diagram, the vulcanized belt is passed under roll 22, over roll 23 and thence to wind up reel 24, which applies a stiffening tension to the belt. Each edge tape is stripped from the belt and folded back on itself at a folding vertex 13 whence it passes over guide roll 25, through a moistening or sizing bath 27, between heated ironing members 28 and 29 and finally on to a storage reel 31.

Title: A novel antibiotic substance and a process for its preparation
Inventor: PHILIPPE JEAN
Filed: 1960-02-17
Abstract: <PICT:0905104/IV (b)/1> A new antibotic designated "antibiotic 362" is prepared by cultivating Streptomyces 362 nov. spec. (ATCC-13694), stated to be a strain of Streptomyces cinnamoneus, or an antibiotic 362-producing mutant or strain thereof, under submerged aerobic conditions within an aqueous medium containing at least one soluble source of nitrogen, and at least one soluble carbohydrate until a marked antibiotic activity is exhibited by the medium. The antibiotic substance may be recovered from the medium by salting out the impurities, preferably by the addition of acetone, ammonium sulphate or a mixture of zinc chloride and sodium hydroxide, extracting the antibiotic from the medium, preferably by means of a phenolic compound, and finally lyophilising a concentrated antibiotic solution.  Antibiotic 362 is a polypeptide which is soluble in water, phenol and m-cresol, is less soluble in methanol and is insoluble in butanol, chloroform, ether, carbon tetrachloride, acetone and ethyl acetate; its ultra-violet absorption spectrum has a slight maximum at 270 mm  and its infra-red spectrum is as in the Figure, the abscissae showing wave-lengths in microns and the ordinates percentages of light transmitted.  The abscissae at the top of the Figure represent waves per centimetre.

Title: Improvements in or relating to the treatment of molten metals and alloys

Filed: 1938-02-22
Abstract: 510,369. Refining metals; alloys; beryllium chromate. GILBERT, W. V. Feb. 22, 1938, No. 5633. [Class 82 (i)] [Also in Group III] Molten metals and alloys, particularly magnesium and aluminium, are treated with beryllium chromate which may for example be enclosed in fusible material such as metal foil. The chromate may be mixed with the solid metal and the whole heated to above the melting point. Some beryllium and chromium may be retained by the metal. In some cases a metal different from that being treated may be added at the same time as the chromate, whereby alloys are formed ; in this way cobalt may be added to magnesium, silicon or niobium to aluminium, titanium to copper, and indium to silver. An aluminium alloy may be made by melting together 95 per cent. of aluminium, 4 per cent. of copper, 0.5 per cent. of manganese and 0.5 per cent. of magnesium, and adding to the alloy when melted 0.5-1.5 parts of beryllium chromate. Beryllium chromate suitable for use in the process may be made by mixing beryl with alkaline hydroxide, oxide, or carbonate, fusing, dissolving the product in water, adding ammonium carbonate, filtering, neutralizing with chromic acid, washing, and drying. Specification 441,126 is referred to.
