IPC: B05B7/10
Filed: 1958-08-06
Abstract: 866,276. Liquid fuel atomizers. ROLLSROYCE Ltd. July 27, 1959 [Aug. 6, 1958], No. 25270/58. Class 75(1). A fuel injector for a gas turbine engine comprises a swirl chamber 14 having an atomizing orifice 21<SP>1</SP> and means for directing fuel over an external wall 14b of the swirl chamber 14 towards the atomizing orifice 21<SP>1</SP>. The fuel passes through a filter 11 into a chamber 17. Part of the fuel then passes into the swirl chamber and is discharged through the atomizing orifice 21<SP>1</SP>; another part of the fuel passes through radial tappings 18 in the chamber 17 to an annular chamber 19 on the exterior surface of the swirl chamber 14 and then through a small gap between the swirl chamber 14 and a clamping nut 16 to an' annular orifice 21 adjacent the external wall 14b of the swirl chamber. A flow of combustion air is directed over the external wall 14b by a shrould 22 having air inlets 23a. In a modification the gap leading to the annular orifice 21 is fed with fuel by radial holes in the side wall of the swirl chamber and in another modification by passages extending from an aperture in the back wall of the swirl chamber. In a further modification the injector comprises a pilot swirl chamber surrounded by a main swirl chamber and fuel is conveyed from the main swirl chamber through an aperture in the side wall thereof to a gap leading to an annular orifice adjacent the end wall of the main swirl chamber. Specification 694,483 is referred to.

The reciprocation is effected by a lever 20, engaging a collar 21 on the shaft 11, and actuated by a stepped cam 22 formed so as to produce the particular arrangement of graded loops required. In order to provide for the omission of certain loops, the operative stroke of the finger 10 may be prevented at particular reciprocations of the shaft 11 by adjustable stops 28 one or more of which may be brought into the path of fingers 27 on an arm 26 secured to the shaft.

Patent GB-761195-A (GB)
Title: Flame-proofing of wood
IPC: B27K3/15
Filed: 1954-09-02
Abstract: Wood is flame-proofed by treating it with a solution comprising a tetrakis hydroxymethyl phosphonium salt and/or tris hydroxymethyl phosphine oxide, and a polyfunctional organic nitrogen compound capable of reacting with formaldehyde, or the partially polymerized reaction product thereof, and completing the polymerization.  The polyfunctional nitrogen compound is one having more than one hydrogen atom attached to nitrogen or to a carbon atom in an aromatic nucleus or more than one methylol group or at least one of each.  Examples are urea, melamine, guanidine and alkenoyl amides such as acrylamide; their methylolated or alkylated methylolated derivatives; and their low molecular weight condensation products with formaldehyde. Suitable phosphonium salts are the chloride, acetate, phosphate, formate and sulphate.  The solutions may be aqueous or in organic solvents, e.g. mineral spirits.  The latter case, they may contain alkyd resins and pigments and fillers, and are useful as surface coating compositions.  A catalyst is preferably used when the phosphine oxide or a weak salt of the phosphonium compound is used, and may be acidic or basic, e.g. hydrochloric, acetic and other conventional acid catalysts, and alkali metal carbonates and bicarbonates, triethanolamine and diethanoamine.  Specification 740,269 is referred to.

Oxidation may be effected with air which may be ozonised. Alternatively a solution of an oxidising agent, such as hydrogen peroxide, sodium bromate, sodium percarbonate, sodium persulphate or ammonium persulphate, at a pH above or below 7, may subsequently be applied.  To adjust the pH to below 7 an organic acid, such as lactic or monochloracetic acid, may be added, and to adjust the pH to above 7 the solution may contain ammonia or an amine.  As a further alternative, a solution of an oxidising agent containing an alkaline agent and, if desired, an antioxidant, such as a mercaptan or sulphite, may be mixed with the solution or cream containing the indole derivative immediately before use. Numerous examples are given.  Specifications 797,174 and 823,503 are referred to.
Patent GB-257094-A (GB)
Abstract: 257,094. C.L.I. Manufacturing Co., Ltd., and Laird, J. A. Aug. 15, 1925. Switches partly electromagnetic; electromagnetic switches. - For controlling lighting and ignition apparatus on motor road vehicles in accordance with the speed of the vehicle an automatic switch is employed mounted upon the generator and having a contact c mounted upon a blade, spring b adjusted to a given frequency. The blade spring carries an armature a which co-operates with a pair of pole-pieces d, e associated with a permanent magnet f. At a particular speed of the vehicle the vibration set up puts the blade into sympathetic vibration until finally the contact c engages a fixed contact g where it is held by the engagement of the armature with the polepieces. In order to separate the contacts a polar projection i is provided with a winding h through which a demagnetizing current may be momentarily passed. Instead of actuation by mechanical vibration, the armature may be set into oscillation by the alternating leakage flux from the generator field magnets when at a certain speed of the generator the alternations reach the given frequency. To accentuate the leakage flux the switch is secured to the magnet structure of the generator by steel screws m.

Abstract: 1535816 Dynamo-electric machines SIEMENS AG 23 June 1976 [7 July 1975] 26005/76 Heading H2A In an electric drive device comprising a stator and rotor carrying a first pair of windings together forming a series commutator motor and a second pair of windings together forming an induction motor providing a lower output speed than the series motor, the supersynchronous braking torque of the induction motor is reduced when the device is running at a speed higher than the synchronous speed of the induction motor. The stator and rotor are slotted, laminated bodies, some of the slots on both stator and rotor accommodating coil sides of the windings of both motors. The induction motor secondary winding comprises coils connected in series to form a closed circuit. This closed circuit may be interrupted by a centrifugal switch at speeds above the synchronous speed of the induction motor. Alternatively the same effect can be achieved by winding the induction motor to have a higher pole number than the series motor.

Abstract: 584,303. Hydraulic tappets. ORD, L. R., and ORD, L. C. Dec. 28, 1944, No. 26007. [Class 7 (vi)] A valve tappet with two members 1 and 2 in telescopic relation and an oil or other fluid chamber 3 between them for maintaining axial adjustment, say between a cam and valve stem has a shoulder 18 on the tappet body 2 which compresses the fluid supplied through the port 15 in the chamber 14, and then through passage 13 and ball valve 8 and 9 to the chamber 3. A pressure relief piston 20 supported by a spring 21 and prevented from passing passage 13 by an annular stop 22 deflects downward when the pressure in the chamber 14 becomes too high, the fluid leaking past the piston being drained away through a passage 26. The members 1 and 2 are constrained axially by the spring 7. In a modification the spring supporting the piston rests on the shoulder of the tappet members and acts downwardly on the piston whose annular stop is contained on said member. In another modification the piston is internally mounted in a chamber contained wholly in the said member. In a further modification the valve to the chamber between the two telescopic members is of a spring loaded disc type and the central pressure relief piston is supplied with a spigot which enters the inlet passage to the said chamber.
