Title: Improvements in luminescent materials
Inventor: RANBY PETER WHITTEN
IPC: C09K11/67
Filed: 1952-10-18
Abstract: 737,474. Luminescent materials. THORN ELECTRICAL INDUSTRIES, Ltd. Sept. 30, 1953 [Oct. 18, 1952], No. 26194/52. Class 39 (1). A luminescent material comprises magnesium borate activated with titanium, wherein the percentage relative weights of magnesium, titanium and boron expressed as oxides are 50-85, 5-40, and 2-27 per cent respectively. The material may be made from a mixture containing magnesium and boron as oxides or in any compound easily decomposible to oxide on heating, such as magnesium titanate or magnesium metaborate, Mg(BO 2 ) 2 . The mixture is heated to 1125 to 1225‹ C. for ¢ to 2 hours in a closed silica tube or in an open crucible in an atmosphere of air, nitrogen or steam, but not in a strongly reducing atmosphere as this causes reduction of the titanium compound. The material is then ground and exhibits a deep blue fluorescence when excited by 2537Š radiation. Additions of magnesium or barium chloride or of barium or sodium sulphate may be made in amounts from 0.2 to 10 per cent by weight of the total oxides, which assists the reaction of the starting materials. Specific examples are given and the X-ray diffraction data are listed.

Title: Improvements in or relating to shell fuzes
IPC: F42C15/24
Filed: 1925-10-20
Abstract: 264,582. Dardier, S. V. Oct. 20, 1925, Projectile fuzes.-Relates to mechanical time fuzes provided with one or more vanes, which are kept stationary by the air during flight while the projectile rotates, the relative rotation operating a reducing gear train, which releases a firing pin after a given travel. According to the invention, the vane or vanes B are protected from injury, and prevented from being rotated, by means of a guard or housing D, which sets back on discharge and liberates the vanes. In the form shown, the housing D, Figs. 1 and 2, is a split cylinder situated in an annular recess A<3> and normally held in the safe position by its grip on the nose A of the fuze in conjunction with a shoulder d<1> and shear wires d. Slots D1 in the housing engage the vanes to prevent their rotation. The vanes B are hinged to a central part B<2> and swing out when released until stopped by lugs b<2>, Fig. 4. A cover may be fitted over the nose of the fuze to be detached before the fuze is used. The Provisional Specification also describes an inertia member for uncovering the percussion cap on discharge, a centrifugal firing pin released by the gear train, inertia members adapted to cut key-ways in the rotatable nose of the fuze, thus to lock the nose against rotation during Bight to preserve the setting of the fuze, and registering holes to ensure correct alignment of parts in assembling.

Title: Improvements in insoluble coloured products or pigments and process for manufacturing the same
IPC: C09B69/06
Filed: 1936-09-30
Abstract: Coloured pigments are obtained by bringing together, at ordinary temperature, an acidreacting salt, e.g. an aluminium salt, and a natural or synthetic basic colouring-matter of either mineral or vegetable origin.  The acid-reacting salt may advantageously be employed in conjunction with colloidal silica obtained, for example, by the action of an acid on an alkali silicate.  In examples, (1) a slurry obtained by stirring dried halloysite into an aqueous solution of Methyl violet is filtered and dried, (2) an aqueous solution of Methyl violet is added to a slurry obtained by stirring a solution of sodium silicate into a mixture of halloysite and water, hydrochloric acid is added to precipitate colloidal silica and the product is washed, filtered and dried.

Abstract: 1,179,605. Series-thyristor converters. ALLMANNA SVENSKA ELEKTRISKA A.B. 9 June, 1967 [10 June, 1966], No. 26635/67. Heading H2F. [Also in Division H3] To equalize the current distribution between thyristors in a series-connected chain paralleled by a C.R. voltage divider, at least some of the capacitors have series inductors having a greater impedance for the capacitor discharge current on firing of the thyristor than for the charging current during the blocking period. Such impedance difference may be achieved by using a saturable iron-core inductor alone (Fig. 3, not shown) or in series with an air-core inductor (Fig. 4, not shown). Alternatively, a diode may be shunted across the inductor-resistor series combination (Fig. 2a, not shown).

Title: Improvements in or relating to high explosives
IPC: C06B21/00
Filed: 1939-09-26
Abstract: 537,579. Explosives. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 26, 1939, No. 26679. Convention date, Oct. 10, 1938. [Class 9 (ii)] A cast explosive charge for shells, grenades, mines &c. comprising a mixture of a highly explosive organic compound or compounds, such as trinitrotoluene, and an oxydizing salt or salts, such as ammonium nitrate, is prepared by mixing the salt or salts with an emulsifying agent and heating the mixture to form a melt, the explosive organic compound being then incorporated in the melt. Suitable emulsifying agents are colloids which do not react with the salts or with the high explosive compound and do not coagulate in the concentrated saline medium at the working temperature of from 80‹ to 110‹C., for example, clays of the type known as bentonite, colloidal pentoses or hexoses, vegetable gums and amylaceous substances like dextrin, starch or flour. Organic crystalline substances soluble in water to form syrups of high viscosity, such as sugar or honey, may also be used. A third group of suitable emulsifying agents comprises organic mineral substances which while insoluble in water have a high absorbent power due to their porosity, for example silica gel, kieselguhr, finely ground cellulose, porous carbon and the like. Emulsification is preferably effected in the presence of water either in the free state or in the form of the hydrated crystalline salts such as magnesium nitrate, sodium acetate in admixture with sodium nitrate, and disodium phosphate. Examples of charges prepared according to the invention are given.

Gill bars in a push-bar type of gill frame are controlled by a chain 2 driven in synchronism with the bars 1 and provided with teeth 10 that engage between the ends of alternate bars 1 throughout their upper reach to prevent relative displacement of the bars. A chain 2 may be employed at each side of the machine and the tension of each chain is adjustable. To provide easy access to the bars 1, the chains 2 may be swung upwardly clear of the bars. Means for adjusting the height of the chains 2 may also be arranged.

The oligodynamic materials include silver, copper, bismuth, antimony, manganese, nickel and aluminium, and their alloys. The bodies may be in the form of balls, short rods. or pieces of wire, and may be loose in the treatment vessel or inserted in a bag, cage or other holder, or may be fixed so as to maintain predetermined spaces therebetween. The bodies may be joined together to form a structure which is fixed in the vessel. The vessel, for example, may have tubes or other projections rising from its walls or bottom, and walls may be composed of or wholly or partly coated with the metals or alloys. The treatment may be preceded or followed by filtration, which may be in a filter containing the metals or alloys.. The sterilizing device may have heating and cooling means, and also means, such as a stirrer, pump, or a device for introducing a blast of air or other gas or vapour acting continuously or intermittently, to agitate or move the liquid. Reference is made to the prior use of vessels lined with, or containing wire formed from the metals or alloys, and of filters consisting thereof or coated therewith. Specifications 11938/10; 21332/11, [Class 81 (i), Disinfecting &c.] ; 157,280 and 180,973 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of carriers coated or combined with the metals or alloys as the oligodynamic bodies; the use of bodies in the form of woven or plaited fabric or of fibrous or granular matter and the disposition of the bodies during the oligodynamic treatment to give a filtering effect. This subject-matter does not appear in the Specification as accepted.
