Title: Improvements in electrical measuring devices
IPC: H04Q1/32
Filed: 1949-02-22
Abstract: 657,229. Current measurements. GENERAL ELECTRIC CO., Ltd., HALLIDAY, V. N., and RALPH, F. E. Feb. 22, 1949, No. 4800. [Class 37] In order to measure the ratio between the make and break periods of impulsing contacts such as are used in automatic telephone systems, the contacts are arranged to form one arm of a bridge, the other arms of which comprise resistors which can be adjusted so that the bridge is balanced when the impulse ratio has a desired value. One arm of the bridge consists of a fixed resistor R14, a second arm comprises resistors R9 ... R13, any one of which may be selected by a switch arm S3, a third arm consists of resistors R1, R2 selected by a switch arm S1, and the fourth arm consists of the impulsing contacts P, the ratio of make to break of which is to be measured. Across one diagonal of the bridge is connected a galvanometer G with centre zero, reading mean current. Its sensitivity is adjusted by resistors R3 ... R7 selected by a switch arm S2. A resistor R8 and key KS act as a safety byepass. Vibration of the galvanometer needle at impulse speed is minimized by a smoothing circuit formed by an inductor L and capacitor C. Current is supplied to the second diagonal through a switch KO, a switch KA being momentarily closed so as to operate a relay X which locks over its contact x and starts the impulse machine IP which carries the contacts P. Variation of the ratio of the opening and closing of these contacts affects the mean current through the galvanometer G, which may be calibrated in degrees of inaccuracy by adjustment of the resistors R3 ... R7. When the impulse machine is operating correctly the switch arms S1, S2, S3, which are operated by a common handle, are set for the ratio which the impulsing contacts are designed to give and a switch KB is closed. The circuit may be adapted for use in connection with a dial or like impulse sender in which the number of impulses emitted during any train of operations is limited. The dial is provided with a circuit to supply the bridge with a whole number of impulses, say 9, the galvanometer being out of circuit until the arrival of the first impulse to be measured. Repeated operation of the dial permits a reading of the galvanometer to be taken if the dial ratio is too high or too low.

Title: Improvements in the manufacture of aliphatic acids
IPC: C07C51/12
Filed: 1937-02-19
Abstract: The reaction of carbon monoxide on methyl alcohol is effected in the presence of nitrogen compounds of oxy-acids of phosphorus dispersed in the reaction mixture which is passed through a tube containing a filling of copper turnings or gauze to which a silver compound has been applied or which is plated with silver on a part of its surface, as traces of copper and silver compounds facilitate the reaction. Specification 283,989, [Class 2 (iii)], is referred to.ALSO:Acetic acid and/or methyl acetate is produced by reacting methyl alcohol with carbon monoxide in the presence of a nitrogen compound of a phosphorus oxy-acid dispersed in the reaction zone. Suitable catalysts are an ammonium or substituted ammonium (e.g. pyridinium) salt of a phosphorus oxyacid, or a partially amidated phosphorus oxyacid or ester thereof or a fully amidated phosphorus oxyacid.  The catalyst may be used in the form of vapour, or, if not easily volatile may be injected as a solution for instance in water, acetic acid or methyl alcohol.  The production of free acetic acid is favoured by the presence of water vapour.  Methyl acetate and any dimethyl ether that may be produced may be returned to the reaction vessel.  The reaction temperature may be 250-450 DEG  C. and the reaction may be effected in a tube containing a filling of copper turnings or gauze to which a silver compound has been applied or which is plated with silver on a part of the surface, since traces of copper and silver compounds facilitate the reaction.  Specification 283,989, [Class 2 (iii)], is referred to.

Abstract: 306,409. Viet, P. Feb. 16, 1928, [Convention date]. Driving-arrangements.-In a momentum apparatus for starting aircraft or other engines, for operating the turntables of aircraft machine guns or cruisers &c., or for other purposes, the mass to be set in rotation includes two or more small electric motors set in rotation around an intermediate shaft by their own motive power. In the engine starter shown in Fig. 1, electric motors 7 are rotatably mounted in a casing 17 rotatable in a fixed casing 12, two, four or six motors being arranged around the axis of the casing. Pinions 9, 10 on the armature shaft of each motor gear respectively with a fixed toothed rim 11 on the casing 12 and with gear teeth 13 on the casing 14 of a multiple plate clutch 15, 16 by which a sleeve 6 is driven. When the motors 7 and the casing 17 have been set in rotation by supplying current to the motors, a shaft 3 within and splined to the sleeve 6 and carrying a clutch 4 is moved axially into clutching engagement with the engine shaft 1 by means of a pedal 20 or a hand lever 21, Fig. 3. In order to prevent this engagement until the rotating parts have acquired sufficient momentum, a groove 31 in the shaft 3 is engaged by spring- controlled members 18, which are pivoted on the sleeve 6 and are disengaged from the groove by centrifugal action when a sufficient speed is attained. Current is supplied to the motor 7 by a fixed contact ring 24 and brushes 25, 26. The hand lever 21, Fig. 3, has four positions, in which (A) the motors are switched on; (B) the clutch is thrown in, the switch remaining closed; (C) the switch is opened; and (D) the clutch is disengaged. In a modification the motors are arranged radially, a bevel pinion 37, Fig. 7, on the armature shaft of each motor gearing with a fixed ring of teeth 38 and with an idle gear 39 meshing with gear teeth 40 on the casing of the multiple plate clutch.
