Title: Improvements in or relating to gas chromatography
Inventor: MARTIN ALBERT EDWIN
IPC: G01N30/74
Filed: 1954-10-18
Abstract: The components of a gas mixture which have been separated by gas chromatography are detected and analysed quantitatively by passing the component gases over an oxidizing agent and then leading them to an infra-red gas analyser.  The separation may be effected by passing nitrogen through a tube containing a mixture of kieselguhr and dinonyl phthalate into which the gas mixture has been injected.  When inorganic gases have been separated, the oxidizing agent, e.g. copper oxide at dull red heat, converts carbon to carbon dioxide, hydrogen to water vapour, and sulphur to sulphur dioxide; these products are estimated by means of the infra-red analyser and the amount of the gaseous component in the mixture is calculated.
Patent GB-1007665-A (GB)
Title: Process for resolving racemates and mixtures of enantiomorphs of amino acids
IPC: C07C/
Filed: 1962-08-03
Abstract: A racemate or mixture of enantiomorph of a basic amino acid (e.g. lysine, arginine or ornithine) is resolved or partially resolved by adsorbing the amino acid on an optically-active cation exchanger which has been produced by amide formation between a weakly acidic cation exchanger in the acid form and an optically active amino-dicarboxylic acid (e.g. L-glutamic acid or L-asparaginic acid), and then selectively eluting one enantiomorph with a basic eluent, e.g. an aqueous or an aqueous alcoholic solution of ammonia or an aliphatic amine of up to 4 carbon atoms. The process may be repeated, and any unwanted enantiomorph may be recemized and the racemate again treated as above.
Patent GB-409031-A (GB)
Title: Improvements in or relating to non-metallic resistors and the manufacture thereof
IPC: H01B1/04
Filed: 1932-10-26
Abstract: 409,031. Resistance materials. CARBORUNDUM CO., Ltd., Trafford Park Road, Trafford Park, Manchester.- (Globar Corporation; Niagara Falls, New York, U.S.A.) Oct. 26, 1932, No. 30038. Drawings to Specification. [Class 37.] In order to increase the specific resistance of non-metallic resistors, particularly those composed principally of silicon carbide, a comminuted metal such as aluminium powder is added to the non-metallic mixture and the resistor is subsequently cured at a temperature of 1800‹ C. or greater in an atmosphere which is non-oxidizing with respect to the principal non-metallic conducting ingredient. In an example, a small quantity, usually from 1 to 5 per cent of aluminium powder is mixed with dry silicon carbide grain and a small quantity of sodium silicate solution is added to serve as a temporary binder, the mixture then being moulded to the required shape. The moulded resistors are then baked at a low temperature, e.g. 600‹ C., dipped in a slip or slurry consisting of an aqueous suspension of very finely divided sand and carbon in equal proportions, and dried. The resistors are placed end to end between electrodes in a bed consisting of a mixture of 3 parts of fine silica and one part of carbon by weight in a furnace as described in Specification 366,605, current being passed through the resistors so that they are heated to about 2000‹ to 2500‹ C. in an atmosphere containing carbon monoxide and silicon vapour generated by the interaction of the silica and carbon of the bed. A small proportion (about 2.5 per cent.) of carbon flour may be added to the mixture before moulding. Other easily oxidizable metals and alloys, such as magnesium and magnesium-aluminium alloys, may be used instead of aluminium. Other non-metallic resistance materials, such as carbon or graphite, may be employed instead of silicon carbide. For example, powdered aluminium may be added to crushed particles of carbon, a carbonizable binder such as tar or pitch added, and the formed resistor cured at a temperature of 1800‹ C. or greater. Specification 15390/05, [Class 37], also is referred to.

Abstract: 1321110 Dynamo-electric machines ALLMANNA SVENSKA ELEKTRISKA AB 24 June 1970 [25 June 1969] 30644/70 Heading H2A An electric motor comprises a salient pole stator providing a set of stator pole faces, a rotor having a set of rotor pole faces, the pole faces of one of the sets being of greater arcuate length than those of the other, and stator windings M 1 , M 2  connected sequentially to a D.C. power supply under the control of a rotor position sensor, the path for the flux produced by the stator windings having, adjacent a stator/rotor interface, a zone of restricted cross-sectional area, which area increases from zero to a maximum during each pass of a rotor pole past a stator pole, the zone being such that this maximum occurs after the leading edge of the larger pole has passed the trailing edge of the smaller pole, and saturation occurring in the zone even at the maximum. In Fig. 1, the rotor poles are each twice the length of the stator poles 2, 3, 8, 9, but over the leading portion of each rotor pole part of the iron is removed, e.g. by punching holes 6 or omitting portions of alternate laminations (Fig. 2, not shown). When the leading edges of the rotor poles begin to overlap one pair of stator poles (say, 2, 3) the associated winding M 1  is connected to the supply so that the rotor is pulled anticlockwise into its minimum reluctance position. Owing to the punchings 6, this position is not reached until the trailing portions of the rotor poles are beneath the stator poles 2, 3, at which time the leading edges of the rotor poles are beginning to overlap the other stator poles 8, 9. The supply is thereupon switched from the winding M 1  to M 2  so that rotation continues. A thyristor-controlled switching circuit for the windings is disclosed (Fig. 3, not shown), which includes an arrangement for keeping the current supplied substantially constant.
