Title: Improvements in the manufacture and production of new vat colouring matters
IPC: C09B3/30
Filed: 1922-11-27
Abstract: New vat-dyestuffs dyeing or printing in grey to blue-black shades are prepared by the action of hydroxylamine on a dibenzanthrone compound; a solution of hydroxylamine as obtained by the electrolytic reduction of nitric acid may be used.  The products are possibly aminodibenzanthrones, and their sulphuric acid solutions take up nitrous acid in quantity corresponding with a monoamino compound; the dyestuff isolated from this solution dyes cotton in more bluish shades.  In examples, a solution of dibenzanthrone in sulphuric acid is acted upon with hydroxylamine sulphate or hydrochloride in the presence of copper sulphate, or with hydroxylamine sulphate alone. Specification 16538/04 is referred to.

IPC: C03B37/092
Filed: 1952-12-24
Abstract: 721,990. Glass and like fibres. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 23, 1953 [Dec. 24, 1952]. No. 32704/52. Drawings to Specification. Class 56. In the drawing of fibres of glass or other vitrifiable material by extrusion of the fused material through nozzles and subsequent attenuation, the supply is drawn from a source having the proper viscosity and which is surrounded or contained by vitrifiable material too viscous for drawing and which may, in fact, be actually solid. The proper viscosity of the supply is maintained by passing a current therethrough after preheating. By maintaining the nozzles at an appropriate temperature it is arranged that they become and remain lined with vitrifiable material which is too viscous for drawing and which prevents the low viscosity glass &c. from contacting the insides of the nozzles and from spreading from one nozzle to another.
Patent GB-917896-A (GB)
Title: Improvements in or relating to devices for safeguarding against pulsating direct current a load to be fed with alternating current
IPC: G05F1/42
Filed: 1960-09-23
Abstract: 917,896. Control systems for consumption apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 23, 1960 [Sept. 28, 1959], No. 32775/60. Class 38 (4). In order to prevent a load supplied from an alternating current source over reversely connected discharge tubes from being subjected to currents having a direct current component, arrangements are made so that the tube which was conductive last in one operation does not begin a subsequent operation. The Figure shows an embodiment in which a welding transformer L is supplied during an even number of half-cycles from an A.C. supply over reversely connected discharge tubes 1, 2. A negative grid bias Vg prevents the ignition of a tube B 1  with the result that a tube B 3  is ignited and pulses from a transformer TP 1  cause tube B 2  to ignite whilst tube B 4  remains extinguished. Closure of a switch S short-circuits the grid bias Vg so that upon the occurrence of a positive voltage peak from the transformer TP 1  tube B 1  ignites whereupon main tube 1 ignites by the agency of transformer T 1  and tube B 3  extinguishes. Current then passes to the load L for a half-cycle of the supply producing by means of a transformer TO a positive voltage at the anode of tube Be which, upon the receipt of a grid voltage peak from a transformer TP 2  fires to produce a peak at the grid of tube B 4 , by way of transformer T 4 . Tube B 4  fires, extinguishing tube B 2 . At 180 degrees after the grid peak at B 1  a grid peak occurs at tube B 2  which re-ignites to fire the main tube 2 by way of a transformer T 2  and extinguish tube B 4 . Current then passes to the load for the next half-cycle of the supply, thereby producing by way of the transformer TO a positive voltage at the anode of tube B 5  which fires, similarly to the operation of tube B 6 . The firing of tube B 5  ignites tube B 3  extinguishing tube B 1  and hence the main tube 1. The operation will be repeated whilst the switch S is maintained closed and will be terminated by the opening of the switch S. At whatever moments the switch S is made or broken the main tube 1 will always ignite first and the main tube 2 last. Thus the transformer in the load L will never be magnetized by successive pulses of the same polarity. In another embodiment either tube B 1  or tube B 2  may be started first but in this case steps must be taken to ensure that the main tube which ended an operative period is not that which starts the next operative period. The system can be reset by a push-button Dr.

Title: A process for the production of sugar-containing juices from vegetable materials
IPC: C13B10/14
Filed: 1947-12-12
Abstract: In the extraction of sugar from sugar-containing parts of plants, especially beets, the latter part of the extraction at least is effected with water acidified by the addition of an acid-reacting salt such as aluminium chloride, so that the extract has a pH of 4.3-4.9, preferably 4.5-4.7.  If desired the treatment can be started with water brought to a pH of 2.5 by the addition of an acid-reacting salt provided this be adjusted before the temperature at which inversion starts is reached.  A relatively pure juice is obtained which can be further purified, without liming and carbonation, by passage through cation and anion exchangers, the former being a synthetic resin treated with an acid-reacting liquid, and the latter a synthetic resin prepared from an aliphatic or aromatic amine or imine and treated with an alkaline liquid.  The Specification as open to inspection under Sect. 91 refers also to the use, as acid-reacting salts, of aluminium sulphate and ferric chloride.  This subject-matter does not appear in the Specification as accepted.
