Inventor: WALKER HERBERT
IPC: H01G4/015
Filed: 1954-05-24
Abstract: 773,796. Capacitors. BRITISH INSULATED CALLENDER'S CABLES, Ltd. May 23, 1955 [May 24, 1954], No. 15265/54. Class 37. In the manufacture of a wound-type, capacitor having as dielectric a thin film of a synthetic plastic material, e.g. polythene or polyethylene terephthalate, the film is moistened during the winding process in its passage from the supply coil to the winding means. The liquid used for moistening the film is preferably water or a dilute aqueous solution of ammonia or of a non-ionic wetting agent, the film being drawn through a bath containing the liquid and between a pair of felt-covered rollers immersed in the bath. The then layer of liquid formed on the film serves to lubricate the film during winding thence reduces the likelihood of the film creasing. It also assists in the discharge of electrostatic charge which may accumulate on the film and washes off particles of foreign matter. After winding, the capacitor is dried by heating in a vacuum.

Patent GB-612301-A (GB)
Title: Process for the production of araliphatic amines
Filed: 1946-05-23
Abstract: Araliphatic amines having analgesic properties and of the general formula <FORM:0612301/IV(b)/1> p  wherein R1 represents an unsubstituted or substituted aromatic radical (e.g. phenyl, halogenphenyl, alkylphenyl, hydroxyphenyl, alkoxyphenyl, hydroxyethoxyphenyl, benzyloxyphenyl, acyloxyphenyl, nitrophenyl, naphthyl, methylnaphthyl, ar.-tetrahydronaphthyl or phenanthryl), R2 and R3 represent alkyl radicals (e.g. methyl, ethyl or n-propyl), and R4 represents hydrogen, a saturated aliphatic or cycloaliphatic radical (e.g. methyl, ethyl, isopropyl, butyl or cyclohexyl) or an aralkyl radical (e.g. benzyl), are manufactured from saturated ketones of the general formula <FORM:0612301/IV(b)/2> or the corresponding a  : b -unsaturated ketones by the following methods: (1) treating the saturated ketones with reducing agents such as aluminium amalgam or catalytically activated hydrogen in the presence of the appropriate amines or (in the case of catalytic hydrogenation) of ammonia; (2) condensing the saturated ketones with formamide or the appropriate N-substituted formamides and saponifying the resulting formyl compounds; (3) reducing the saturated ketones to the secondary alcohols, esterifying these with a halogen hydracid and reacting the resulting halides with ammonia or the appropriate primary amines; (4) (when R4=H) reducing the oximes or hydrazones of the saturated ketones; (5) subjecting the unsaturated ketones to one of the foregoing processes of hydrogenating amination, whereby the double bond is simultaneously saturated.  If desired, substituents in the aromatic radical R1 may be converted to hydroxy groups or split off as follows: (a) a nitro group may be reduced to amino and converted to hydroxy by diazotization; (b) alkoxy or acyloxy groups may be hydrolysed to hydroxy; (c) halogen atoms may be replaced by hydrogen concurrently with the reduction of Schiff's bases formed as intermediate products, or subsequently.  Primary amines (R4=H) obtained as above may be alkylated, cycloalkylated or aralkylated, e.g. by the action of halides or sulphates of alcohols or by treatment with aldehydes or ketones with reduction.  Examples illustrating the various features of the invention and tables of additional products thereof are given.  Ketones of the general formula given above are obtainable by aralkylating ketones which contain replaceable hydrogen at an a -carbon atom.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of compounds of the general formula above in which R3 may represent a cycloalkyl radical and R4 an unsaturated aliphatic or cycloaliphatic radical.  Reference is also made to the diazotization of 1 - (41 - aminophenyl) - 2 - methyl-3-N-methylaminopentane to replace the amino group by hydroxy, and to the production of 1-(41-methoxyphenyl)-2-methyl-3-N-ethylaminopentane by the action of ethylamine on the corresponding 3-bromo compound (obtained by treating the 3-hydroxy compound with phosphorus tribromide).  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to coin-freed mechanism applicable to gas and similar meters
IPC: G07F15/02
Filed: 1919-06-23
Abstract: 149,117. Simpson, S. June 23, 1919. Electricity and gas-supplying by meter; coin action, mechanical-connexion; price-changing mechanism.-Apparatus for connecting the coinholder and the measuring-wheel, applicable to meters of the kind described in Specifications 22830/97 and 21721/11, comprises a pawl a mounted on the front face of the price-change disk b and projecting through a slot therein to engage the ratchet-teeth f of the measuring-wheel g, the paw.. being locked in its operative position bv a limited motion of the coin-holder k before the coin becomes operative to rotate the plate. The pawl, which is mounted in lugs d stamped from the plate b, has a pin i extending outwardly into the space j between the plate b and the coin holder k. The coin-holder has a cavity n formed therein adjacent to the coin slot to receive the pin i on the return movement of the coin-holder. After insertion of a coin, the initial movement of the coin-holder removes the pin i from the recess n and causes the projection of a tooth h on the pawl into engagement with the ratchet f of the measuring-wheel. Further movement of the coin-holder brings the coin into contact with a stop s projecting from a radial arm q, which may be adjusted to different positions relatively to the disk b in accordance with the price of the commodity. If the coin-holder is reversely rotated after a partial forward rotation, the coin itself engages an extension o of the pawl and keeps the pawl in the locked position. A pin t is provided on the rotating plate to engage a radial part of the coin-holder, so that the return movement of the coin-holder may be transmitted to the rotating plate.

Patent GB-1049622-A (GB)
Title: A method of preparing tetracycline
IPC: C12P29/00
Filed: 1964-04-16
Abstract: Tetracycline is recovered from a fermentation broth in a high degree of purity by acidifying a tetracycline-containing fermentation broth to pH 1.5 to 2.0, filtering off the mycelium and adjusting the tetracycline content of the filtrate to at least 0.3% w/v., adding alkali to adjust the pH to 3.0 to 6.0 to convert the tetracycline into the amphoteric form so that the solution is converted into a supersaturated solution of tetracycline and allowing the tetracycline to crystallize.  The tetracycline content of the filtrate is adjusted by (a) concentration, (b) addition of the concentrated mother liquor from a previous batch, or (c) addition of the metal complex obtained from (b) by adjusting to pH 8 to 8.5 with alkali. Prior to the precipitation of tetracycline, proteinaceous impurities are removed by the addition of a wetting agent such as dibutylnaphthalene sulphonate at pH 3.4.

Abstract: 1403282 Oscillator circuits TOYO TSUSHINKI KK 3 April 1973 [3 April 1972] 15800/73 Heading H3F The invention relates to a temperature-compensated crystal oscillator in which compensation over a temperature range is obtained by using three crystals Nos. 1, 2, 3 connected in parallel, the combination being connected across a negative resistance source R L  in series with capacitance C L . The crystals all have parabolic frequency/temperature characteristics, the turnover temperature of Nos. 1, 3 being equally spaced on either side of that of No. 2. According to the invention, the inductances of crystals Nos. 1, 3 are made substantially equal, while that of the central crystal, No. 2 is made higher. Alternatively, external inductance may be added in series with this crystal. The Specification gives a mathematical explanation, showing that if this is done, the arrangement remains stable with temperature change even when it is tuned over a frequency range.
