Abstract: 844,761. Ion trapping in cathode ray tubes. FERGUSON RADIO CORPORATION Ltd. April 15, 1957 [April 23, 1956], No. 12404/56. Class 39(1). An annular ion trap permanent magnet with diametrically opposite poles is fixedly mounted on the tube neck by means of an extruded annular strip of polyvinyl chloride which has a cross-section equivalent to two channel members back to back, one of the channel members holding the annular permanent magnet and the other channel member gripping the tube neck resiliently. The mounting strip is split and the ends thereof may but preferably do not touch. The sides of the larger channel are splayed outwardly and have beaded edges so that they grip the slightly over sized tube neck by resilient pressure. The cathode ray tube has an inclined gun, the ion trap magnet deflecting electrons but not negative ions on to the axis of the tube neck. The Provisional Specification states in addition that the strip may be moulded and may be of any material having elastomeric properties.

Title: Process for the preparation of condensation products of dialkyl xanthines and quaternary ammonium hydroxides
Inventor: LADENBURG KURT
IPC: C07D473/08
Filed: 1956-04-24
Abstract: Condensation products of the general formula <FORM:0822915/IV (a)/1> (wherein R1, R11 and R111 are alkyl groups of 1 to 3 carbon atoms, R is an alkyl group of at most 16 carbon atoms which may be substituted by hydroxy, alkoxy or aryl groups and X is a dialkylxanthinate radical or an 8-substituted dialkylxanthinate radical the alkyl groups of which each contain one to three carbon atoms) are prepared by reacting a sulphite, bisulphite or thiosulphate of a quaternary hydroxide of the general formula <FORM:0822915/IV (a)/2> in an aqueous medium with a dialkylxanthine or an 8-substituted dialkylxanthine HX, preferably with heating.  Advantageously, an inert organic solvent such as isopropanol with or without benzene is added to the reaction mixture, and after the condensation reaction a substantial amount of the water present is removed by azeotropic distillation.  In an example sulphur dioxide is bubbled into a cooled aqueous solution of choline, theophylline is added and the mixture is heated until SO2 evolution ceases, some of the water is distilled off under vacuum at 50 DEG  to 55 DEG  C. and then isopropanol is added and an azeotrope is distilled off under vacuum at 40 DEG  C. to give, on cooling the remaining mixture, choline theophyllinate crystals. Reference is also made to the use of other quaternary ammonium hydroxides variously containing methyl, benzyl, hexyl, octyl, decyl and dodecyl radicals and to the use of other dialkylxanthines such as theobromine, paraxanthine and 8-chloro-, -bromo- or nitrodialkylxanthines in the process of the invention.  Specification 376,443 is referred to.

Title: Telegraph system
IPC: H04L1/18
Filed: 1964-03-25
Abstract: 1,023,984. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. March 25, 1964 [April 1, 1963], No. 12589/64. Heading H4P. In a system in which a subscriber is connected to an exchange which includes means for correcting errors by repetition, reception at the exchange of a signal from the remote subscriber indicating that repetition is taking place causes a preset character to be passed to the subscriber's printer, which recognizes the coding of the character and passes a signal to the transmitter to stop the tape distributer, thereby preventing pile-up of tape during the repetition. The circuitry for generating the present character, Fig. 2 (not shown), comprises a transistor multivibrator whose mark-space ratio is adjusted to produce the preset signal when triggered by the repetition signal. The repetition signal disconnects the subscriber's receive loop from the exchange and connects it to the multivibrator output. At the subscriber's printer the preset character triggers a slow-torelease relay which breaks the distributer drive circuit for a period substantially longer than a character period. The exchange may be a multiplex unit.

The oxidation in the first pair of V 2 O 5  and iron oxide catalyst beds may be carried out until the temps. are in the ranges 550-620 and 690-760 C. respectively. The final temp. of the iron oxide catalyst bed in the second or subsequent pair of beds may be lower, e.g. 630-710 C. The pair of V 2 O 5 /iron oxide catalyst beds may be in the form of two layers interposed with a layer of heat-insulating material, the gases preferably being passed upwardly through the beds.

An illumination system, particularly for concentrating radiation from a source on to a selected area of a relatively remote surface comprises a source 10 emitting radiation on both sides of its equatorial plane and a plurality of reflectors each having a central aperture and one focus located at the source, the reflectors including main reflectors 12, 16, 24 arranged to reflect radiation in a common direction to a target and which are located on both sides of the equatorial plane so that the areas of the main reflectors projected normally on to said plane are substantially contiguous and non- overlapping and a reflector 20 in the shape of a zone of a sphere, this reflector extending from the equatorial plane in a direction opposite to the direction of reflected radiation and being disposed intermediate said plane and a zone subtended by one of the main reflectors. Radiation from reflector 20 impinges on reflectors 12 and 16 in substantially the same geometrical relation as radiation coming directly from the source 10. The reflectors 12, 16 and 24 are ellipsoids of revolution. The source 10 is an arc and the reflectors are oriented so that their foci are located at different points along the arc. The reflector 16 may be made up of four quadrants which may be slightly tilted from the theoretical position where an unsymmetrical pattern of illumination is desired and the optical axis of reflector 24 may also be slightly inclined to the axis of the system. The arrangement of reflectors provides a large amount of open passage for ventilation of the system.
