Title: Improvements in or relating to electric follow-up devices for measuring instruments
IPC: G01R17/04
Filed: 1935-08-12
Abstract: 465,938. Electric follow-up devices. SOC. FRANCAISE DE METROGRAPHIE. Aug. 12, 1935, No. 2417/37. Convention date, Aug. 2, 1935. Divided out of 462,663 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 14, 1936. [Class 40 (i)] In a follow-up device, more particularly for positioning numeral wheels of weighing apparatus, a searching member, which normally occupies a zero position, hunts for the position of an index pointer to operate the numeral wheels and when engagement with the pointer is established, the member is unclutched and restored to the zero position. Fig. 1 shows two numeral wheels 61, 65 driven from a motor 79 through gearing 80, 81, 85, 87 the wheels being geared through gearing 72, 73. A searching arm 99 loosely mounted on the shaft 66 of the wheel 65 is adapted to be clutched to the shaft when a pivoted lever 146 is forced into engagement with an abutment 145 by a rod 102 which is moved longitudinally in the shaft 66 when a magnet 108, Fig. 6, is operated at the commencement of a measuring operation. When the searching arm 99 overtakes the index 26, Fig. 6, magnet 118 is operated and a relay 113 previously operated by press button 109 is released and the motor 79 is stopped. Simultaneously magnet 108 is de-energized and the arm 99 is unclutched and restored to normal by a spring 143. Magnet 91 also is operated to cause a pawl 89 to align the numeral wheel 61. If the wheel 61 is outside the region of zero, contacts 120, 121, Fig. 2, are closed by a cam 93 to operate magnet 124 and a pawl 125, Fig. 5, moves the wheel 65 backwards into its proper position. If the wheel 61 is however within the region of zero contacts 120, 122 are closed and magnet 126 operates an auxiliary pawl 127 which is displaced slightly relatively to the relative position of the pawl 125 and the aligning teeth of the wheel 65. The pawl 127 enters the correct tooth space, the wheel 65 is moved backwardly and pawl 125 operated by magnet 124, which is also energized upon energization of magnet 126, correctly aligns the wheel. The magnet 124 also operates the printing relay 134 which pulls up relay 136 to effect release of the pawl actuating magnets. Contact 138 is operated when the driving lever 146 is off-normal and consequently upon operation of relay 136, the motor 79 is operated to drive the numeral wheels to normal. Specifications 418,987 and 456,850, [both in Group XVIII], are referred to.

Title: Enzymic Oxidation of alcohols and aldehydes
IPC: C12N9/02
Filed: 1966-06-06
Abstract: 1,153,151. Enzymic oxidation of alcohols and aldehydes. MOBIL OIL CORP. 6 June, 1966 [7 June, 1965], No. 25111/66. Heading C2C. Alcohols and aldehydes are enzymically oxidized to aldehydes and alkanoic acids respectively by a method comprising growing cells of a hydrocarbon-oxidizing micro-organism on a nutrient medium using a hydrocarbon having substantially the same number of carbon atoms as the starting alcohol or aldehyde as the sole source of carbon, harvesting the cells and rupturing the same in an aqueous medium, extracting from the cells a crude aqueous enzyme extract, optionally isolating from said crude extract an enzyme having specificity for the starting alcohol or aldehyde, mixing the crude extract or the isolated enzyme with the alcohol or aldehyde, incubating the mixture in the presence of molecular oxygen, DPNH oxidase and a sufficient amount of DPN<SP>+</SP>  oxidase to enzymically oxidize the alcohol or aldehyde to product aldehyde or alkanoic acid containing the same number of carbon atoms as the starting material, and at the same time reducing DPN <SP>+</SP> cofactor to reduced cofactor DPNH from which DPN<SP>+</SP> is regenerated by DPNH oxidase to maintain amounts of DPN<SP>+</SP> in the incubating mixture. The enzymes induced by growing cells on, e.g., a C 10  hydrocarbon exhibit specificity for oxidizing C 8-12  aldehydes and alcohols. The crude enzyme extract contains DPN<SP>+</SP> and DPNH oxidase but addition from a commercial source may be required; an alternative source of addition DPN<SP>+</SP> and DPNH oxidase is from cells grown on a non-hydrocarbon carbon source, e.g. glucose. The crude enzyme extract may contain enzymes which control the oxidation of hydrocarbons, alcohols, aldehydes and alkanoic acids and the required enzymes may be isolated, e.g. chromatographically. Such isolation removes DPN<SP>+</SP> and DPNH oxidase from the enzyme and these must be supplied from a different source. Examples relate to the use of enzymes isolated from Achromobacter sp. grown on decane to oxidize decanol to decanal and decanal to decanoic acid. Other enzymes isolated from the crude mixture can be used to oxidize decane to the decanol starting material. The process is illustrated by reference to flow diagrams (not shown).

Title: Stepper motor circuits
IPC: H02P8/20
Filed: 1962-01-24
Abstract: 931,627. Electric selective signalling systems. AUTOMATION DEVELOPMENT CORPORATION. Jan. 24, 1962 [March 6, 1961], No. 2687/62. Class 40 (1). A circuit, Fig. 2, for controlling a stepping motor, Fig. 1, is characterized in that each pulse applied to a clockwise lead CW causes the rotor 11 to make one step of 90 degrees in a clockwise direction and each pulse applied to a counter-clockwise lead CCW causes the rotor to make one step in a counter-clockwise direction. In operation, if a clockwise pulse (CW pulse) is applied it passes through one of four gates 28 (which may comprise relays, thermionic tubes or transistors), the one chosen being determined by the last coil of the stator to be energized, and emerges on one of four leads a, b, c, and d, to energize an associated solenoid 19, 20, 21, 22 which energizes the next stator winding in the clockwise direction and, by a mechanical interlock not shown, de-energizes the previously energized solenoid. Thus, if solenoid a is energized, as shown, a CW pulse passes through gate ACW and energizes solenoid b which causes stator winding B to be energized and solenoid a to be released. The operation with CCW pulses is similar. In a modification, intermediate positions of the rotor (45 degree steps) are obtained by energizing pairs of windings. In further modifications, pairs of diametrically opposite windings are energized simultaneously to give greater torque.

Title: Improvements in or relating to electric discharge lamps
IPC: H01J61/86
Filed: 1939-01-27
Abstract: 569,651. Discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., ALDINGTON, J. N., and CREASY, W. G. Jan 27, 1939, No. 2903. [Class 39 (i)] In mercury vapour lamps operating at pressures over 5 atmospheres, the electrodes 3 are formed of solid blocks of thoriated tungsten and are used both for starting and running purposes. Starting is facilitated by the addition of an inert gas such as argon or neon, or a mixture of such gases, at a pressure of the order of 50 m.m. of mercury. The thoriated tungsten may be made by making a paste of thorium nitrate and tungsten trioxide, drying, igniting to decompose the nitrate and reducing by heating in hydrogen. In one arrangement, the electrodes 3 are in the form of rods of uniform diameter up to the point at which they are sealed into the bulb 1. In another arrangement, the electrode comprises a head and a shank around which is a closelywound helix of heavy tungsten wire. Three or more electrodes may be used to produce several coalescing are discharges. The bulb is of quartz and may be enclosed in a sealed outer jacket which may be evacuated or have a filling of gas of good thermal conductivity. Alternatively the surrounding jacket may be in the form of an open cylinder. The sealing of the leading-in conductors may be made as described in Specifications 512.941 and 512,974, [both in Group XXXVI].

Patent GB-671721-A (GB)
Title: Improvement in organo-silicon derivatives of cellulose
IPC: C08B15/05
Filed: 1950-02-06
Abstract: A chemical product consisting essentially of a triorgano silyl derivative of cellulose in which there is an average of 0.25-2.0 triorgano silyl groups per glucose unit of the cellulose molecules is obtained.  The triorgano silyl groups are of the formula (R2R1Si-) where R is an aryl radical and R1 is an aryl or alkyl radical, and each of the silicon atoms is attached through an oxygen atom to a cellulose carbon atom which before the substitution would normally carry a hydroxyl group.  As aryl radical there may be used a phenyl, xenyl, tolyl, xylyl, or naphthyl group.  The alkyl group may be methyl, ethyl, propyl, butyl, amyl, hexyl, octyl, dodecyl, or octadecyl.  A partially esterified or etherified cellulose containing 1-2.75 ester or ether groups per glucose unit of the cellulose may be used in making the silicon derivative.  Cellulose nitrate, acetate, or p-toluene sulphonate, or a cellulose methyl, ethyl, propyl, butyl, benzyl, allyl, hydroxy ethyl, triphenyl carbinyl or carboxy methyl ether, may be used.  The cellulose ester or ether may be etherified with a triorgano silicon halide preferably in presence of a hydrogen halide acceptor such as pyridine, ammonia, piperidine, or other amino compound.  The reaction may be effected at room temperature.  Films may be obtained by casting a solution of the organo silicon cellulose derivative in an aromatic hydrocarbon or an ether on to a smooth surface, evaporating the solvent, and stripping the dried film.  The films may be used for insulation of electrical equipment, and for packaging.  The organo silicon cellulose derivatives may also be used for making articles by moulding or extrusion.  Pigments, fillers, and finely-divided dielectric solids may be incorporated.  In an example, methyl cellulose containing 1.7 methoxy groups per glucose unit is suspended in pyridine.  A solution of triphenyl chloro silane in pyridine is added.  Reaction proceeds at once and a clear viscous solution of the methyl cellulose silane reaction product is obtained. The solution is left for 2 days and then poured into dilute hydrochloric acid solution.  The viscous mass is washed with water and then dissolved in benzene.  The solution is cast to form a transparent film containing 1.3 triphenyl silyl groups per glucose unit of the cellulose.  In other examples, ethyl cellulose containing 2.4 ethoxy radicals per glucose unit is reacted with diphenylethyl chloro silane, and cellulose acetate containing 2 acetyl groups per glucose unit is reacted with triphenyl chlorosilane.
