Title: Improvements in axial-flow compressors
Inventor: WILDE GEOFFREY LIGHT
IPC: F04D27/02
Filed: 1947-06-04
Abstract: 652,095. Axial-flow compressors. ROLLS-ROYCE, Ltd. June 4, 1947, No. 14825. '[Class 110(i)] [Also in Group XXIX] A multi-stage axial-flow compressor has a number of sections, at the entry of each of which there is a row of adjustable stator blades the pitch of which is adjusted in accordance with the rotational speed of the compressor or a condition dependent on the speed, to a value appropriate to reduce the tendency to stalling in the section at that speed. Stator blades 11a, Fig. 2, are pivoted in inner and outer trunnion bearings 15 and are interconnected so as to move in unison by means of rocker arms 19 each engaging a notch in a rotatable ring 21. A second row of stator blades 11b are pivoted at their outer ends only and are interconnected by rocker arms 28 and a ring 29. At speeds below a predetermined value, the blades 11a are set to increase the swirl and the blades 11b are set to decrease the swirl, for the purpose of preventing stalling. When the speed of the compressor exceeds the predetermined value, a centrifugal governor 36, Fig. 1, closes an electrical circuit to energize a solenoid 41. The solenoid moves a piston valve 42 against the action of a spring 47 into the position shown. This reverses the connections of a hydraulic pump 43 to hydraulic actuators 26, 34 which act through linkages 23, 31 to alter the pitches of the blades 11a, 11b to the normal running values. The centrifugal governor may be replaced by a pressuresensitive governor comprising two capsules actuated by the inlet and outlet pressure respectively of the compressor. The capsules are connected to opposite ends of a beam which is pivoted at such a point that it rocks to close the electrical circuit when, the ratio of outlet to inlet pressure exceeds a predetermined value. There may be more than two rows of adjustable stator blades. The blades may be made to occupy more than two positions, or there may be a follow-up mechanism between the governor and the blades so that the pitch is progressively varied in accordance with the compressor speed. The compressor may be driven by a gas turbine.

Abstract: 1408582 Copying apparatus SEACO COMPUTER-DISPLAY Inc 27 July 1972 [28 July 1971] 15081/75 Divided out of 1408581 Heading B8R The apparatus described and illustrated is as in the parent Specification 1,408,581, but the claims are directed towards the storage tray 200 and the means for applying the developer. As shown in Fig. 3, the tray 200 for storing the copy sheets 202 has an inclined forward edge 210 which, unlike the remainder of the tray, is not coated with insulating material. Thus this edge serves to reduce electrostatic and frictional forces between adjacent sheets as they are fed forward one by one to the charging station F. At the developer station G the sheets pass between a roller 340 and a deflector plate 338. Roller 340 extends across the width of the apparatus, and the developer is applied through a nozzle 342 extending along the length of the roller. The nozzle has a plurality of guide vanes 341 along its length for controlling the flow of developer. This is pumped from a reservoir supply 354 through a conduit 350 and connector 348 offset at one end of the nozzle. The fluid is ejected against the underside of the copy sheet, and a small trough 398 of liquid is created between roller and sheet. Excess liquid is removed by a spring-loaded pair of squeegee rollers 372, 374 which have a non-cylindrical section (Fig. 13, not shown).

Title: Improvements in or relating to spinning machines for producing artificial filaments and yarns
IPC: D01D5/04
Filed: 1942-11-02
Abstract: A spinning machine for producing artificial filaments or yarns comprises a plurality of spinning cells, a duct for conveying gaseous medium to the cells, and means for supplying to the gas inlet of each cell gaseous medium <PICT:0562860/IV/1> <PICT:0562860/IV/2> from two portions of the duct so that all the spinning cells are supplied with gaseous medium at substantially the same temperature.  The gas inlets may communicate with an intermediate mixing chamber into which gaseous medium passes through openings in the supply duct, the openings adjacent each inlet being situated in portions of the duct at which the gaseous medium is at different temperatures.  As shown, preheated air or other gas is introduced into the spinning cells 1 through pipes 2 and is withdrawn through pipes 4.  The air is distributed to the spinning cells by the manifold 5 which comprises a duct 6 having portions 7, 8 which communicate with the intermediate chamber 9 through oppositely spaced openings 10, 11.  The pipes 2 are connected to chamber 9 through the side wall at positions midway between openings 10, 11.  The cross-sectional area of the duct gradually diminishes so that the velocity of the air passing through the duct is substantially uniform, the duct being sufficiently large in cross-section so that the pressure drop in the duct is small in comparison with the absolute pressure.  Air from portions 7, 8 of the duct on entering chamber 9 becomes mixed and the temperature of the air in the chamber is substantially uniform.  Instead of having a mixing chamber 9, common to all the spinning cells, there may be provided a plurality of small chambers each communicating with a pair of openings 10, 11, and a single cell.

Title: Improvements in and relating to electric contact converters
IPC: H02M1/26
Filed: 1951-06-29
Abstract: 688,958. Converting. BRITISH THOMSONHOUSTON CO., Ltd. June 29, 1951 [July 5, 1950], No. 15497/51. Class 38 (ii). An electric contact converter comprises a plurality of sequentially-operated contacts to effect the transfer of energy between alternating and direct current circuits, two conductors which are alternately energized as the contacts are operated, an inductive device connected between the two conductors and a capacitor arranged to be charged in response to current flowing in the conductors and effective to aid in transferring current from one conductor to the other. The contacts 1-6 are sequentially operated by means of a rotating cam 8, driven by a synchronous motor M, so that current flows from the A.C. supply by way of a transformer TP, TS and the contacts 1-6 to the D.C. output D.C.- 1, D.C.-2 through one or other of the saturable reactors R1, R2 and the autotranstormer HT. The contacts 1-6 are so connected that sequential operation thereof alternately energizes the reactors R1, R2, the pre-saturation of which is supplied by the A.C. generator G, driven by the motor M, and regulated by an adjustable impedance 14, the reactors functioning to limit the current flow through the contacts 1-6 to a low value when these contacts are opened. Flow of current through one of the reactors-say R1 and the left-hand portion of the auto-transformer HT- causes a condenser HC to be charged with a polarity such that the left-hand terminal thereof is positive. At the point where the current is to be transferred from one contact to another, this potential will be effective to reduce the potential tending to maintain current flow through the contact being broken and to increase the potential across the contact about to be made, thereby the condenser HC functions to facilitate the transfer of current from one contact to the next. Similar operation occurs when current flows through the reactor R2 and the right-hand portion of the auto-transformer HT, the condenser HC in this case being oppositely charged. The functioning of the condenser HC is particularly effective during rapidly changing load conditions. In another embodiment the auto-transformer HT is replaced by a conventional two winding transformer, the condenser HC being connected across the secondary winding thereof. The apparatus may also be used as an inverter.

Title: Improved process for the utilisation of solid carbonaceous fuels
IPC: F23C10/00
Filed: 1946-05-22
Abstract: A method for the generation of heat from solid carbonaceous materials comprises passing an oxidizing gas through a fluidized mass of coal or coke admixed with a solid non-combustible material to burn the combustible constituents of the mass, the non-combustible material being present in a quantity to produce a mixture undergoing combustion having a carbon content at least below 25 per cent and preferably between 0.1 and 5 per cent by weight.  The non-combustible material may comprise inert material such as sand, clay, furnace ash and the like or it may comprise catalytic materials capable of increasing the oxidation reaction rate of the carbon such as iron oxide, iron ore, rusty scrap iron, high iron clays, red mud, spent cracking catalysts and the like. The heated solids obtained by the combustion are used to supply heat to an endothermic chemical reaction by circulating the heated solids continuously between the zone in which the combustion is effected and the zone in which the endothermic reaction is being carried out.  In an application to the carbonization and gasification of coal by a fluidized process in which separate carbonization, gasification and combustion zones are provided, inert material is charged together with the coal to the carbonization zone and constitutes about 10 per cent by weight of the charge, the gasification residue fed from the gasification zone to the combustion zone thereby having a carbon concentration below 5 per cent and possibly between 0.1-1.0 per cent.  Specification 586,391, [Group XII], is referred to.

Title: Improvements in or relating to light filters
Filed: 1935-05-30
Abstract: A colour filter absorbing ultra-violet radiation is made by incorporating an appropriate pyrene compound with a solvent or a carrier, examples of suitable compounds being 3, 5, 8, 10-pyrenetetrasulphonic acid sodium salt, 3, 5-dimethoxypyrene, 3-benzoylaminopyrene-para-disulphonic acid sodium salt, and the urea of 4<1>-aminobenzoyl-3-aminopyrenedisulphonic acid sodium salt.  The following preparations are given in examples: (1) during the further working of normally prepared paper material, one per cent of the sodium salt of 3-benzoylaminopyrene-p-disulphonic acid (prepared by benzoylating 3-aminopyrene with benzoyl chloride and sulphonating) is added to the mass which is then converted into parchment paper in the usual manner; (2) one part of 3, 5-dimethoxypyrene, prepared by treating 3,5-dihydroxypyrene with dimethyl sulphate, is dissolved in 99 parts of nitro-cellulose lacquer and the solvent is evaporated; (3) the sodium salt of pyrene-3, 5, 8, 10-tetrasulphonic acid dissolved in water is mixed with an aqueous solution of phenylbenzimidazole sulphonic acid sodium salt; a liquid fatty mixture prepared by melting together anhydrous lanoline containing camomile extract, anhydrous lanoline and wool fat and adding thereto a -phenyl-b -(p-methoxyphenyl)-acrylic nitrile (prepared by adding 50 ccs. of a 12 per cent sodium methylate solution drop by drop to a mixture of 1 mol. of p-methoxybenzaldehyde, 1 mol. of benzyl cyanide and 500 ccs. of methyl alcohol and allowing to stand) is then mixed with this aqueous salt solution; (4) cellulose hydrate foil is passed through a bath containing the urea of 4<1> - aminobenzoyl - 3 - aminopyrene disulphonic acid sodium salt at 50 DEG  C.  The said urea is prepared by condensing 3-aminopyrene with nitrobenzoyl chloride in pyridine solution and sulphonating the condensation product, the reaction mixture being poured on ice and salted out with NaCl.  The 4<1>-nitrobenzoyl-3-aminopyrene-disulphonic acid sodium salt thus obtained is reduced with iron powder in the presence of acetic acid to the corresponding amino compound which, in the form of the free acid, is salted out by adding HCl.  The reaction product is then treated with phosgene to obtain the desired urea. Specifications 441,408 and 447,483 are referred to.
