Title: Pulse controllers
IPC: H02M3/137
Filed: 1975-04-08
Abstract: 1491339 Control of D.C. motors SEVCON Ltd 8 April 1976 [8 April 1975] 14361/75 Heading H2J To reduce the size of a common commutating capacitor 27 forming part of a control circuit for two reversible D.C. series motors 1, 5 and 3, 7, which circuit comprises main thyristor 19, 21 switching current for the respective motors from a battery 17, commutating thyristors 23, 25 and capacitor charge reversal circuit 29, 31, a control circuit 33 operates to fire the thyristors 23, 25 one at a time at intervals not less than the time required, from the commencement of commutation of thyristor 19 or 21, to forward charge the capacitor 27 and then reverse its charge. The invention may be applied to control D.C. loads other than motors or to more than two motors of various sizes, the capacitor then being chosen to be capable of commutating the current associated with the largest motor. In the described embodiment, the motors drive respective left and right hand wheels of an electric vehicle and a firing control circuit 35 for the thyristors 19, 21 is responsive to the vehicle accelerator pedal and steering mechanism to vary the currents supplied to the respective motors. Control may be by pulse width and/or pulse frequency. In the embodiment each thyristor 19, 21 is commutated at constant time intervals (a-a, b-b) which are the same for both thyristors, the commutation instants being staggered so that the intervals (a-b, b-a) therebetween are equal, Fig. 2 (not shown). Each thyristor 19, 21 is controlled by circuit 35 so that it cannot be fired until a sufficient time has elapsed, following its commutation, to allow capacitor 27 to be discharged and fully forward charged. Further control of thyristor 19 or 21 may be such that they are commutated at intervals which are a multiple of the intervals (a-a, b-b), for example by suppressing a commutation pulse at the end of an interval (b-b) to produce an interval (b-b<SP>1</SP>) twice as long, Fig. 2 (not shown), and so increase the current supplied to motor 3.

Title: Improved process for the manufacture of dicyanostilbenes
Filed: 1940-09-25
Abstract: 543,204. Dicyanostilbenes. MAY & BAKER. Ltd., and BARBER, H. J. Sept. 25, 1940, No. 14543. [Class 2 (iii)] Dicyanostilbenes are prepared by re-acting a 4: 4<SP>1</SP>-, or a 2: 4<SP>1</SP>-α-#-tetrabromo-diphenylethane with a cuprous salt to produce the corresponding 4 : 4<SP>1</SP>-, or 2 : 4<SP>1</SP>-dibromostilbene, and treating the product with cuprous cyanide. The cuprous salt for the first stage in the process is preferably cuprous bromide or chloride which is used in a solvent such as pyridine or quinoline. Cuprous cyanide may also be used in the first stage of the re-action, in which case the amount used must be regulated to two molecules for each molecule of tetrabromo-compound. For the final stage of the re-action an excess of cuprous cyanide is preferred. A modification of the process consists in treating the parent tetrabromocompound with an excess of cuprous cyanide to produce the required dicyanostilbene in a one-stage process. In examples (1) α-#-diphenylethane is brominated to the 4 : 4<SP>1</SP>-α-#- tetrabromo compound, which on treatment with cuprous chloride and pyridine is converted into 4 : 4<SP>1</SP>-dibromostilbene, and this compound on treatment with cuprous cyanide yields 4 : 41-dicyanostilbene. (2) . 4 : 4<SP>1</SP>-α-#-tetrabromodiphenylethane is converted directly into 4 : 4<SP>1</SP>-dicyanostilbene by treatment with excess of cuprous cyanide and pyridine. (3) 4 : 4<SP>1</SP>-α-#-tetrabromo-diphenylethane is converted into 4: 4<SP>1</SP>-dibromo-stilbene by treatment with the theoretical amount of cuprous cyanide and pyridine and then into 4:4<SP>1</SP>- dicyano-stilbene as described in example (1). Specification 510,097 is referred to.

Abstract: 744,738. Printing processes. LINDMARK, J. G. May 20,1954 [May 23, 1953], No. 14801/54. Class 100 (2). [Also in Group XV] A method of printing multi-coloured pictures or the like on a transparent base material comprises matting one surface of said material, and printing the differently coloured picture components laterally inverted on the matted surface and in the reverse of normal order, e.g. in the sequence black, red, blue and yellow, so that the final picture will be direct and correctly coloured as viewed through the base material. The surface may be matted by blasting with sand or other abrasive material. A transparent foil may be disposed on a drum rotated at high speed, while one or more sand-blasting nozzles maintained parallel and directed towards the drum are moved longitudinally of the drum in one direction at a constant, comparatively low velocity. After blasting, the dust is blown off and the foil is brushed off and flushed with a cleaning liquid, such as pure water. After printing, a continuous covering layer of white or other light colour may be applied in offset or by an ink-applying roller. The foil may be mounted on an opaque backing such as paper or cardboard by means of a white rubber latex paste, or on a transparent backing of a plastic foil by means of a colourless rubber latex paste. If the foil is to be mounted on thick paper or cardboard, it may be 0.2 mm. thick or less, while for use for open-air signs it may be up to 1 mm. or more thick. A protective sheet of a foil of the same material as the base may be adhesively applied to the printed surface. Printing may be carried out by a lithographic offset, letterpress or photogravure process. The method may be applied for printing coloured illustrations for written works, maps, book covers &c., signs and posters, or the lids of boxes for cigars, cosmetics, &c.
