Abstract: 853,719. Prepayment meters. LANDIS & GYR Ltd. Dec. 9, 1958 [Dec. 11, 1957], No. 38501/57. Class 27 Insertion of a coin in mechanism 2 releases a knob 1 for rotation to set forward the differential mechanism 15 of a prepayment electricity or other meter and the rotation turns a ratchet arm 6 having a pawl 19 which slips over a ratchet wheel 9 geared to the differential mechanism until the arm is arrested by an adjustable stop 20; the pawl 19 then engages the wheel 9 and, during the return motion of the arm 6 by a spring 7, rotates it to set foward the differential by an amount corresponding to the position of the stop. To adjust the position of the stop, a toothed wheel 24 on which it is mounted can be pushed in by a knob 23 to disengage the wheel from a fixed toothed wheel 21 and then the knob can be rotated so that the wheels can re-engage in a different position. To indicate the number of units obtainable per coin according to the setting of the stop, the knob 23 is connected by gears 25 to an indicator 26. To allow full rotation of the knob 1 through 360 degrees at each operation, the drive from the knob to the arm includes rollers 3 acting on an arm 3a which transmits the drive through a spring 5 that is stronger than the spring 7 and deflects after the arm is arrested, until the full rotation of the knob disengages the rollers 3 and arm 3a.

Title: The fermentative production of the antibiotics distamycine and distacyne
Filed: 1957-12-11
Abstract: <PICT:0872734/IV (b)/1> <PICT:0872734/IV (b)/2> New antibiotics distamycine A, B and C and distacyne are produced by cultivating streptomyces distallicus (S distallicus NCIB 8936) in an aqueous nutrient medium containing a source of carbohydrate, nitrogen and mineral salts under aerobic and especially submerged aerobic conditions.  The pH of the medium is 7.6, the temperature of cultivation 280 DEG C. and the duration 100-120 hours.  Specified carbohydrates are glucose, sucrose, maltose and starch and the carbohydrates present in corn steep liquor.  As a source of nitrogen there may be used corn steep liquor, soybean flour and ammonium salts.  Mineral salts may be sodium chloride, calcium carbonate, dipotassium hydrogen phosphate magnesium sulphate, ferrous sulphate and calcium carbonate.  The antibiotics are isolated from the mycelium by extraction with a solvent especially butyl alcohol. Other solvents are 1 to 4 carbon alcohols such as methanol or ethanol, halogen derivatives of aliphatic hydrocarbons, e.g. chloroform, acetone, aliphatic, aromatic or heterocyclic bases.  The entract is concentrated and ether added to precipitate distamycine. Distacyne is recovered from the ethereal mother liquor remaining after the precipitation of the distamycine by allowing the liquor to stand 5 to 6 days, separating the precipitate and recrystallising from 75 per cent aqueous acetone.  Distamycine A is obtained by dissolving distamycine in methanol, adsorbing on acidified alumina and eluting with methanol.  Distamycine B is precipitated from a methanol solution of distamycine by the addition of three volumes of ether.  The ethereal mother liquors are evaporated to dryness and taken up again with ether, the residue being distamycine C. The antibiotics are active against pathogenic fungi and bacteria. Distamycine is a conjugated polyene containing nitrogen; soluble in lower alcohols, pyridine and other organic bases and in glacial acetic acid; insoluble in ether, chloroform, dilute acids and alkali; Rf value for water saturated with butanol is 0.3, aqueous butanol is 0.15, butanol pyridine water (1:0.6:1) is 0.6; butanol acetic acid water (2:1:1) is 0.73; ammonium chloride 3% is 0.04; 60% acetone is 0.8; ultraviolet absorption maxima at 235, 290, 305, 318, 333, 350, 380 and 405 mm  (see Fig. I curve A) and infra-red absorption max. at 2.94, inflection points at 3.00 and 3.05, max. at 6.04 and 6.33, inflection points at 6.10, 6.42, 6.52 and 6.58 and maxima at 5.82, 6.8 and 7.3 microns; it gives a deep violet with conc. sulphuric acid.  <TABS:0872734/IV (b)/1>ALSO:A medicinal composition comprises one or more of the antifungal antibiotics distamycine A, B and C and distacyne (see Group IV (b)) and a carrier compatible therewith.

Tuberactin is produced by aerobically cultivating Streptomyces griseoverticillatus var. tuberacticus, NRRL, 3482 or a tuberactin-producing mutant thereof in an aqueous nutrient medium of conventional composition. Crude tuberactin is isolated from the filtered medium by (a) precipitation with a sulphonic acid dye such as methyl orange, eriochrome violet or Alizarin Red S, and either suspending the tuberactin-dye salt in an organic non-solvent and adding an acid salt of triethylamine to precipitate the corresponding tuberactin-acid salt, or dissolving the dye salt in aqueous acid, extracting the dye with water-immiscible solvent, concentrating the solution and adding a miscible non- solvent to precipitate the tuberactin acidaddition salt; or (b) adsorption on a cation exchange resin and elution with dilute aqueous acid or alkali, followed by neutralization and concentration of the eluate from which tuberactin is precipitated with a non-solvent. Alternatively the filtered medium may be purified by dialysis and gel-filtration, concentrated and the tuberactin precipated with a non-solvent. The crude material is purified by re-crystallization from aqueous-alkanol, chromatography on a column of cation-exchange resin, silica-gel or cellulose, dissolution in water followed by precipitation with triethylamine sulphate and a water-miscible non-solvent, or thin layer chromatography on silica gel with 10% aqueous ammonium acetate/acetone/ 10% aqueous ammonia, 9 : 10 : 0.5 (v/v).

Abstract: 1,260,019. Arc generating devices. S. KATAWOKA. 6 Aug., 1969, No. 39331/69. Heading B3R. [Also in Division H5] A directional arc generating device comprises a plurality of closely spaced similar electrodemembers, for example four, 1, la, 2, 2a as shown in Fig. 1, the electrode-members having inwardly sloped discharge surfaces which form a concaved discharge space and means for connecting selected pairs of the electrodes to an arc voltage supply. Holding means 9, Fig. 9, are for symmetrically holding and assembling said electrode members as an electrode assembly with a longitudinal narrow gap 3 between adjacent electrode members. In use, each pair of opposed electrode members is supplied successively with an arc voltage which may be different phase voltages of an A.C. polyphase voltage. Fig. 6 shows a connection diagram for applying a two-phase voltage to the electrode assembly of Fig. 1. The concave discharge space when subjected to an expansion pressure produced by an electric arc directionally ejects an electric arc as shown in Fig. 5. The electrodemembers are obtained by symmetrically dividing a solid body. It is possible during a cease period of the intermittent arc to connect the circuit with another power source having different current and wave form thereby to switch the arc circuit on a different ejecting condition. It is thus possible to generate alternately long and short arc streams by rapid switching of the arc circuit. Starting of a directional arc may be by a short-circuiting graphite piece to cause a temporary contact thereof in the bottom portion of the discharge space, thereby to generate a short-circuit arc in the central portion of the discharge surface of said space. An alternative method is to apply a high-frequency voltage across the electrode-members, thereby to generate a high frequency arc. The electrodes may be made of metal or graphite.
