Inventor: HUGHES JOHN GEORGE KENNETH
IPC: H01R9/16
Filed: 1966-04-07
Abstract: 1,113,835. Terminals; junction boxes. VOLEX ELECTRICAL PRODUCTS Ltd. 7 April, 1967 [7 April, 1966], No. 15555/66. Heading H2E. A terminal 8 for an electrical junction box 6 has its lower end 9 formed as a spigot adapted to fit a pre-moulded socket 16 in the junction box base, and has a through hole 11 coaxial with the binding screw (not shown) which is received by the upper tapped part 13 of the through hole. The terminal has a diametral slot 14 to receive the conductors to be connected, and the spigot has a diametral slot 15 at right-angles to this slot to allow the spigot to be expanded when a slug 18 is forced into the restricted part 11a of the through hole 11. A sharp circumferential flange 10 on the spigot bites into the periphery of the socket 16, during the expansion of the spigot, to securely fix the terminal in the box. The top edge of the slug 18 when in position stands above the base of the conductor slot 14 so that the clamping pressure of the conductors does not loosen the terminal. The base of the junction box has knock-outs through which conductors can be led to and from the terminals.

Patent GB-578177-A (GB)
Title: Improvements relating to refractory compositions
IPC: C04B35/66
Filed: 1944-08-16
Abstract: Refractory substances, particularly for use as moulds for the precision casting of metal parts, consist of a dry solid composition containing a major amount of a refractory aggregate, and minor amounts of a halide of low hygroscopicity, a non-hygroscopic acid salt, and a non-hygroscopic substance capable of reacting with the acid salt.  The aggregate must be substantially insoluble in the binding-agents, and may be of any nature other than magnesia or chrome ore, preferably ganister ground to pass a 10 mesh and to be held on a 325 mesh sieve.  As halide, ammonium chloride is preferred, but sodium or barium chloride, hydrazine or hydroxylamine hydrochloride, or alkyl or aryl chlorides or hydrochlorides, particularly those of organic bases or amines may be used.  The acid salt is preferably a phosphate capable of splitting of P2O5 which reacts with other ingredients, e.g. sodium, calcium, magnesium, zinc, or alkyl or aryl amine acid phosphates, the acid orthophosphate of hydrazine, or, preferably, ammonium dihydrogen phosphate.  The remaining ingredient may be magnesia but, in view of the setting-shrinkage, the heat and speed of setting, and the fragility of the product, it is replaced, at least in part, by a zirconate or a double zirconium silicate of a metal of the first or second group. In order to increase the setting-time, a fluosilicate, e.g. of ammonium, sodium, calcium, or magnesium may be added, and zirconium carbide or cyanonitride and manganese dioxide may be added to impart expansion in firing.  The ingredients are used in the proportions of 34 c.c. of refractory, 8-12 (preferably 2-8) grams dead-burned magnesite, part of which may be replaced by a zirconium compound, 1-15 (preferably 6-10) grams of acid salt, 4-6 grams of the double zirconium silicate or zirconate varying inversely with the magnesia, 1-6 (preferably 2-3) grams of halide, and 0.1-2.5 grams of fluosilicate.  The acid salt and half the aggregate are milled separately from the remaining materials to avoid possible interaction in the presence of moisture and the products are then mixed together in the dry state.  The material can be stored, and when ready for use, is gauged with approximately 20 c.c. of water.

Title: Manufacture and use of dyes
IPC: C09B51/00
Filed: 1941-12-05
Abstract: 554,233. Dyes. ARGYLE, C. S. Dec. 5, 1941, No. 15694. [Classes 2 (ii), 2 (iii) and 15 (ii)] Dyes for the coloration of textile and other materials are produced by aroylating an amino group of an amino-ortho-nitrodiarylamine, particularly amino-o-nitrodiphenylamine or by condensing a halogen aryl compound and an aromatic primary or secondary amine, at least one of the components containing an aroylamino group, and at least one, a nitro group in a position necessary to yield an onitro-diarylamine. The dyes have the general formula where X represents a -CH 2 - group or a direct linkage and the benzene nuclei carry either no substituents or an arylamino, alkyl, oxyalkyl, cyano, alkylsulphone, sulphonamide, carboxylic amide, halogen or alkoxy group. The aroyl radical is aracyl such as benzoyl or aralkacyl such as phenylacetyl. The nitro group is always ortho to the amino group which unites the two aryl nuclei. Additional nitro groups may however be present. Preferably sulphonic acid and carboxylic acid groups are absent from the dyes. Compounds mentioned include 2 - nitro - 4<SP>1</SP> - benzoylamino - diphenylamme, 4- chlor-2-nitro-4<SP>1</SP>- benzoylamino - diphenylamine, 2 - nitro - 4 - benzoylamino - diphenylamine, 2- nitro - 3<SP>1</SP> - methyl - 4<SP>1</SP> - benzoylaminodiphenyl- - amine, and N-(2-nitro-4-benzoylamino-phenyl)- 1-naphthylamine. The new dyes are of value for colouring cellulose ester or ether solutions, especially lacquers and spinning solutions. 'They may also be used for the colouring of materials formed from synthetic linear polymers, e.g. superpolyamide textile materials. They may be applied to the latter from aqueous baths or be incorporated with the superpolyamides prior to the conversion of the latter into filaments, straws, films and the like. In examples (1) o-nitro-chlor benzene is condensed with monobenzoyl-paraphenylenediamine in the presence of soda ash to produce 2-nitro-4<SP>1</SP>- benzoylamino-diphenylamine, which dyes cellulose acetate a bright golden yellow. (2) 2-nitro- 41-amino-di-phenylamine is condensed with phenyl acetyl chloride to give 2-nitro-41- (phenylacetylamino) diphenylamine. (3) 2- nitro-4<SP>1</SP>-benzoylamino-diphenylamine is dispersed with Turkey Red Oil, diluted with soap solution, and to this is added a cellulose acetate fabric and the temperature raised to 70-80‹C., to give a fabric dyed a bright golden yellow of good fastness.

Patent GB-638873-A (GB)
Title: Improvements in the conversion of fluid reactants in the presence of subdivided solid catalyst particles
IPC: B01J8/28
Filed: 1947-06-17
Abstract: In a process and apparatus for conversion of fluid reactants in the presence of subdivided solid catalyst particles by supplying catalyst and reactant to the lower portion of a reaction zone, maintaining therein, by upward passage of reactant and reaction products, a fluidized dense phase bed of catalyst superimposed by a light phase region, and withdrawing reaction products from the light phase region, the contaminated catalyst passes laterally from the upper portion of the fluidized bed through a substantially vertical partition having a series of vertically spaced fixed and non-adjustable <PICT:0638873/III/1> openings into an adjacent stripping zone and downwardly therethrough in a dense fluidized state countercurrent to a stream of stripping fluid, e.g. steam, flue gas, or inert gas, lateral flow of catalyst into the stripping zone from the lower portions of the fluidized bed through the openings in the partition being precluded by maintaining a higher particle concentration in the stripping zone than in the reaction zone, and stripped catalyst is withdrawn from the lower portion of the stripping zone.  For cracking gas oil to high octane gasoline, the oil is fed in at 16 in Fig. 1, and entrains catalyst from regenerator 3 at 42 and passes to dense bed, maintained at 455-525 DEG  C., 0.34-1.7 atmospheres, and density 320-560 kgms. per cu.m., in reactor 1, whence catalyst is withdrawn through slotted plate 29 into first stripping zone 31, wherein the catalyst level is lower than, and density greater than, that in reactor 1, e.g. 400-632 kgms. per cu.m., and wherein the catalyst passes countercurrent to steam injected at 32.  The stripped volatiles and reaction products pass from reactor 1 through cyclone separator 11.  The catalyst stream flows to second stripping zone 35 countercurrent to steam injected at 37, wherein catalyst density is greater or less than that in reactor 1, e.g. 320-632 kgms. per cu.m., and whence stripped volatiles also feed into reactor 1 at 39.  Finally, the catalyst passes to dense bed, maintained at 540-620 DEG  C., 0.68-2 atmospheres, and density 240-480 kgms. per cu.m., in regenerator 3, wherein it is contacted, before recycling to the reactor, with oxygen-containing gas admitted at 26, waste gases being withdrawn through cyclone separator 20. Perforated distribution plates 18, 33, 38, 28, are provided in reactor 1, first stripping zone 31, second stripping zone 35 and regenerator 3 respectively, to give good contact between catalyst and gases.  The cross-sectional area of the first stripping zone should be less than that of the reaction zone, but the stripping zone may extend below the bottom of the dense bed in reactor 1, and the second stripping zone may be omitted.  Specification 574,064 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of a cylindrical partition to give an annular reaction zone or stripping zone.  This subject-matter does not appear in the Specification as accepted.

Title: Two-stage gas pressure regulator
IPC: G05D16/06
Filed: 1956-05-23
Abstract: 814,982. Fluid-actuated valves. STEPHENSON CORPORATION. May 23, 1956 [May 27, 1955], No. 15945/56. Class 135. A two-stage pressure regulator reducing the pressure of a gas from a very high pressure (2000 1b./sq. in.) to a pressure just above atmospheric (22 lbs./sq. in.) to operate in conjunction, e.g., with a resuscitator or respirator, comprises a three-part casing 10, 12, 14 having high, intermediate, low and atmospheric pressure chambers 30a, 34a, 22 and 18 respectively and primary and secondary valve members 36, 40. Gas at high pressure enters the casing through an inlet 26 passes to the high pressure chamber 30a and thence through a conduit member 32 fixed in the casing to the intermediate pressure chamber 34a. The lower end of the conduit member 32 coacts with a part 36b of the primary valve member 36 which is carried by an annular flexible diaphragm 20 and connected by a flexible sleeve member 24 to the secondary valve member 40. Ports 36c through the part 36b allow intermediate pressure to act on the underside of the diaphragm 20. Gas from the intermediate chamber then passes through a passage 41 between a depending tubular portion of the secondary valve member 40 and the conduit member 32 to the lower pressure chamber 22 and thence through a duct 22a to the valve outlet 38. The valve member 40 formed with an annular ridge 46 co-operates with a floating resilient washer 50 interposed between the ridge and a fixed valve seat 32a on the conduit member 32, and is connected by posts 42 and a plate 60 to a flexible diaphragm 16. The diaphragm 16 is subjected on its upper face to atmospheric pressure and the pressure of a spring 66 on its lower face to low or outlet pressure transmitted through a duct 18a. In operation, when outlet pressure overcomes atmospheric pressure and the pressure of the spring 66, the valve 40 closes and since gas is still being consumed the pressure above the diaphragm 20 and the sleeve member 24 decreases resulting in upward movement of the valve member 36 to close the end of the conduit member 32. The lowering of the pressure above the diaphragm 20 results in a reduction in the outlet pressure and a re-opening of the valve 40 and of the valve 36 until finally outlet pressure of the gas is regulated in accordance with the loading of the spring 66. The flexible sleeve member 24 may be replaced by a bellows member connecting a disc-like secondary valve member to the part 36b of the primary valve member or alternatively an " O " seal ring may be fitted between the tubular portions of the primary and secondary valve members, a groove being made in the secondary valve member to receive the ring.
