Title: Improvements relating to pyrometers and like instruments
IPC: G01J5/28
Filed: 1932-12-09
Abstract: 411,891. Pyrometers. GILBERT, V. H., 19, Souberie Avenue, Letchworth, Hertfordshire, and RADIOVISOR PARENT, Ltd., 28, Little Russell Street, London. Dec. 9, 1932, No. 35012. [Class 97 (iii).] In a pyrometer for use in controlling the heat treatment of materials, e.g. metals, radiations from a predetermined area pass through an interrupter shutter to a light sensitive device which serves to indicate that the desired temperature has been reached or to operate relay mechanism. In the form shown, radiation from the substance 4 under observation passes through the mask 5 and is focused by lenses 6 on the selenium or photoelectric cell 1. An interrupter shutter 8 is placed between the cell 1 and optical system 6, which is provided with an adjustable diaphragm 7 and filter 9. The cell 1 is connected to a thermionic valve amplifier, the output of which operates a relay controlling the heating of the object under examination or bringing succeeding processes into action automatically and closing subsidiary contacts for operating a visible or other signal. In a modification the relay and last amplifying valve may be replaced by a " Thyratron." The apparatus may be arranged to give a temperature indication or control temperature regulating devices when the temperature reaches either end of a predetermined range. The instrument may be calibrated with reference to a standard lamp. Specific. ation 393,411, [Group II], is referred to. Reference has been directed by the Comptroller to Specification 237,952, [Class 97 (iii)].

Title: Process for the production of carboxylic acids by the oxidation of organic compounds
Inventor: COTTERILL COLIN BERTIE
IPC: C07C303/22
Filed: 1956-11-16
Abstract: A process for the production of carboxylic acids of aromatic character comprises oxidising a hydrocarbon of aromatic character substituted by at least one alkyl or haloalkyl group or a partially oxidised derivative thereof and by at least one polar group selected from halogen, -SO2NR1R11(R1R11=alkyl, aryl or H); -OR (R = alkyl, aryl); -NHCOR (R = alkyl, aryl or H); -O.OC.R, (R = alkyl, aryl or H); -SO 3R (R = alkyl, aryl or H); -CONR 1R11 (R1, R11 = alkyl, aryl or H); -NR 1R11 (R1, R11 = alkyl, aryl); benzoyl; substituted benzoyl and alkyl carboxylic ester in the liquid phase by means of molecular oxygen or ozone in the presence of a catalyst comprising the manganese bromide and/or cobalt bromide.  The term "a hydrocarbon of aromatic character" includes also heterocyclic compounds of aromatic character containing one or more alkyl groups connected to nuclear carbon atoms.  The partially oxidised derivatives which may be employed are carboxylic, aldehydo, keto and alcohol derivatives.  The starting material may be an ester formed by the interaction of two partially oxidised derivatives e.g. an ester.  Examples of heterocyclic starting materials are b -picolines substituted with the above defined polar groups in the b -position.  Primary, secondary and tertiary alkyl groups which may be oxidised to carboxyl are mentioned.  The metal bromides may be introduced as such or may be produced e.g. by introducing metal salts soluble in the reaction mixture e.g. the acetates or naphthenates and e.g. bromine, hydrobromic acid or sodium bromide.  Cobalt may be introduced as reduced metal or as carboxyl or oxide.  Halogen lost during the process may be replaced by introducing hydrogen bromide, bromine or a bromo derivative of the aromatic starting material.  The process may be carried out at elevated temperatures and pressures.  Ozone may be employed to accelerate the oxidation of difficulty oxidisable compounds and the oxygen may be produced in situ by decomposition of hydrogen peroxide. Solvents mentioned include aliphatic carboxylic acids containing from 2 to 4 carbon atoms, aromatic hydrocarbons, halobenzenes, e.g. o-dichlorobenzene, aromatic acids and water. Examples relate to the production of p-sulphonamido-benzoic acid, m- and pbenzoxy-benzoic acid and anisic acid.  Additional products mentioned include m-sulphonamido-benzoic acid, p-carboxy benzene sulphonic acid, p-carboxybenzene methyl sulphonate and terephthalomonoamide.  Additional starting materials mentioned include p-toluene sulphonic acid, methyl p-toluene sulphonate and p-toluamide.  Specifications 832,995, 833,438 and 833,440 are referred to.

Title: Improvements in or relating to step motor drive control circuits
IPC: H02P8/14
Filed: 1966-08-05
Abstract: 1,139,335. Control of stepping motors. FUJITSU Ltd. 5 Aug., 1966 [6 Aug., 1965], No.35289/66. Heading H2J. A reversible three-phase stepping motor is adapted for alternate excitation of a pair or a single one of its windings a, b, c, to afford six steps per cycle, three bi-stable circuits 71, 72, 73, being connected to the windings for this purpose. A pulse applied to either input terninal 14 or 15 of each bi-stable circuit causes output terminals 16, 17, to assume the same state as input terminals 12, 13, or 10, 11, respectively. The bi-stable circuits are so cyclically interconnected that, each time a pulse is applied to terminal 2, a circuit is set to a state different from that of the preceding circuit prior to reception of the pulse, the sequence being reversed when a signal is applied to terminal 3. In another arrangement a five-phase motor is adapted for alternate excitation of two or three phases, the cyclical interconnection of five bistable circuits being similar to that shown.

Abstract: 907,298. Cop-winding machines. SCHAFFELD, E., and SCHAFFELD, S., [trading as SCHAFFELD, HUGO [Firm of]]. Nov. 4, 1958, No. 35422/58. Class 120 (2). A tubular cop-winding device comprises a fixedly mounted non-removable driving spindle, a funnellike member having a slotshaped aperture adapted to allow thread to pass therethrough to be wound on the spindle and being adapted to be reciprocatably displaceable along its axis at regular intervals of time, a removal device adapted to remove each completed cop, and a severing device adapted to sever the connecting thread between each successive completed cop. In the embodiment shown, a tubular cop la is wound and formed on the spindle 2 by funnel 3. When this cop has reached its full length a separation point 4 is formed by giving the funnel 3 a quick axial displacement. Continued winding of the thread then creates a new cop 1b at A which new cop displaces the completed one axially along the spindle until the completed cop enters the guide tube 6. The tube 6 is swingable about pivot 5 for doffing the completed cop and cutting means 15 are provided for cutting the thread between the completed cop and the succeeding cop. The doffing operation and the movement of the funnel is effected by hydraulic drive mechanism 11 which is controlled by control apparatus 8 through lever 9 and rod 10. The control apparatus 8 is operated by a completed cop coming into contact with it. Alternatively, the control apparatus may be electrically, more particularly photo-electrically operated and the hydraulic drive means may be replaced by pneumatic, mechanical or electrical means.

Abstract: 619,295. Moulds for reinforced articles. CHAPUIS, E. A. Nov. 30, 1946, Nos. 35561 and 35562. Convention dates, May 14, 1940 and April 21, 1941. [Class 87 (ii)] Reinforcement-supporting members 4, 4<1>, Fig. 1, are adapted to clamp the reinforcement 3 between them until the reinforcement is sufficiently maintained by injected moulding material and are movable transversely of the reinforcement 3 by means 14, 18, operable from outside the mould 1, 1<1>, and causing the members 4, 4<1>, simultaneously to move inwards or outwards. Supports 4, 4<1>, are slidably moveable in opposed holes provided in parts 1, 1<1>, of the mould, and in the retracted position their inner ends, suitably shaped, are flush with the walls of the cavity 2. Each supporting member 4 or 4<1> is secured to a transverse bar 8, the bars 8 on each face of the mould being secured to two parallel longitudinal rods 9 provided at their ends with fingers 15. Two toothed wheels 14, 141, on a shaft 12 mesh respectively with racks 10, 11, 10<1>, 11<1>, formed with oblique elongated openings 16, Fig. 3, in parallel relation and adapted to coact with fingers 15. Actuation of the lever 18 causes the racks to slide in opposite directions as shown in Fig. 3, fingers 15 being displaced along openings 16, thus moving supports 4, 41, to the retracted position, whereupon more moulding material is injected to fill the voids left by the supports. The supports may be removed before the mould is wholly filled, as soon as there is sufficient material in the mould to support the reinforcement, in which case the supply of material is uninterrupted. The reinforcement-supporting device and actuation mechanism is also applicable to a multiple mould comprising a plurality of moulding recesses.

Abstract: 467,616. Switchgear structures; actuating and latching switches. BRITISH THOMSON-HOUSTON CO., Ltd., COX, H. E., and REGIS, E. D. Dec. 24, 1935, No. 35749. [Class 38 (v)] In switchgear structures having at least two isolating or selector switches normally arranged for simultaneous operation, an actuating mechanism is provided comprising two spur wheels 3 and an axially slidable operating shaft 11 carrying gear wheels 12 ... 14, so positioned that in one axial position of the shaft the gearwheels 13, 14 each mesh with one of the spur wheels 3, while in other positions one only of the gear-wheels meshes with one or other of the spur wheels, actuation of the switches being effected by rotation of the shaft 11. The shaft 1 carrying the wheels 3, and the shaft 11 are mounted between a pair of supporting cheeks 2, and each of the spur wheels is connected by a link 4 and coupling lever 6 to a link 7a connected to the operating mechanism of the isolating or selector switch. The levers 6 are pivoted on a shaft 7 journalled in the cheeks 2, and actuate indicating mechanism 8. The spur wheels 3 are toothed for approximately half their circumferences, the teeth being protected by shrouds 9, each of which has an arcuate slot 10 cut in it. The sliding movement of the shaft 11 is effected by means of a lever 17 pivoted at 18 and carrying at its lower end a pin 20 which passes between the gear-wheels 13, 14. The lower periphery of the wheels 3 is provided with spaced notches 21 . . . 23 which, in certain positions of the wheels, engage a pin 24 having a flat 25 cut on it. In these positions a circuit-breaker is connected to or disconnected from the circuit controlled by the switch gear, or is earthed ; the gear-wheels are located in these positions by spring-pressed balls 26 which engage recesses 27 in the sides of the wheels. The pin 24 is interlocked with the circuit-breaker tripping mechanism, so that when it is rotated to the position in which the flat 25 permits rotation of the wheels 3, the circuit-breaker is automatically tripped open. In the earth position of the wheels 3, the notches 10 of the shrouds 9 are opposite the shaft 11, so that in this position only is it possible to move the shaft 11 axially to permit separate operation of the selector switches, which may be desired when the switchgear is to be tested or inspected. As an additional precaution, the lever 17 is provided with a combination lock 28 which prevents its operation unless the key for this lock is obtained from some other portion of the gear, thus ensuring that this portion is in a predetermined condition before the lever 17 can be released.
