Title: Improvements in or relating to the circumferential butt welding of tubular components
Inventor: SLATER DEREK
IPC: B23K9/235
Filed: 1968-09-06
Abstract: 1,255,481. Welding by fusion. A.P.V. CO Ltd. 5 Sept., 1969 [6 Sept., 1968], No. 42605/68. Addition to 1,062,924. Heading B3B. In a method of circumferentially butt welding tubular components, as claimed in claim 1 of parent Specification an auxiliary filler wire of large diameter (over 0À075 inch) is heated by resistance heating. For such heating to be effective a current pick-up zone for the filler wire must be spaced from the weld pool such that the current passes along the wire to the weld pool. This necessitates providing the filler wire with a guide if the entry point into the weld pool is to be readily controlled. This is achieved by having an electrically-insulating sleeve 4, an electrically conductive tube 3 and a lead 7 for electrical energy, Fig. 1, or by having a metallic guide tube 8 which is isolated from a tubular contact 9 by an electrically insulating disc 11. Tube 8 may be made of heat resisting refractory material.

Title: Device for producing controllable thrust
IPC: F03H1/00
Filed: 1964-10-23
Abstract: 1,042,820. Jet propulsion plant. GENERAL ELECTRIC CO. Oct. 23, 1964 [Nov. 5, 1963], No. 43404/64. Heading FIJ. [Also in Division H1] A space vehicle orientation control propulsion unit, Fig. 1 (not shown), comprises a vaporizing device 16 producing a gas, which may at the same time be partially ionized, and a nozzle (10) within which the gas is accelerated and ionized or further ionized by a spark discharge between electrodes 12, 14. Device 16 comprises, a housing 18 of insulating material containing a porous ceramic plug 32, the pores of which contain a readily vaporizable and ionizable material, such as liquid mercury, or a suspension of powdered lithium or caesium in oil. An elastic bladder 38 containing a wick 39 and further vaporizable material causes the material to exude from the right hand surface of plug 32 at 34, 36. The discharge tips 24, 26 of vaporizing electrodes 20, 22 within insulators 28, 30, respectively, project from the surface of plug 32 such that an electrical discharge occurring between tips 24, 26 vaporizes and may partially ionize the material at 34, 36. A discharge then occurs between the electrodes 12, 14 through the gas, accelerating the gas to the right through the nozzle (10) as a propulsive jet. Control of the jet thrust is achieved by varying the rate of supply of electrical pulses to vaporizing electrodes 20, 22 from a pulse generator 40. Power source 42 to electrodes 12, 14 consists of a D.C. supply with or without a capacitor and may be turned on as required. In a modification, Figs. 5, 6 (not shown), the nozzle (62) and an internal concentric bullet (64), form the two accelerating electrodes and in a further modification, Fig. 7 (not shown), concentric tubes (82, 84) form these electrodes, the vaporizable material being contained within the inner tube (84). Figures 3, 4 (not shown), illustrate a still further arrangement of electrodes.

Filed: 1965-10-13
Abstract: 1,133,121. Automatic control of travelling strip. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan.9, 1967 [Oct.13, 1965], No.43429/65. Heading G3R. A loop formed in travelling strip material partially obscures light from a source which is scanned vertically to produce a succession of electrical signals, corresponding to errors in the size of the loop, which are utilized separately and in algebraic combination to correct the size of the loop by controlling the speed of a Ward-Leonard set transporting the strip. In Fig.1, strip metal 2, after being unwound from a reel 1, is transported at constant linear speed by a motor M 2  driving a reel 3 at constant speed. A loop LP in the strip partially obscures a strip light source S so that a photo-cell C, which is rotated to scan the light source vertically, produces recurrent electrical signals corresponding to the depth of the loop. These signals are in the form of pulse trains by virtue of a slotted mask M as shown or by causing the photo-cell output to gate a pulse generator. The numbers of pulses in these trains are compared with a desired number in a counter 10 and any errors are converted to analogue form in a unit 11 and amplified at 12 to correct the size of loop by altering the excitation of a Ward Leonard generator G associated with the drive of reel 1. Successive error signals are added algebraically at 13, converted to analogue form at 14 and amplified at 15 to alter the excitation of Ward Leonard motor M1 and thereby introduce an integral component of control.

Title: Methods for preparing and utilizing non-alkali metal quinolinolates and preparations obtained therein
IPC: D06M13/50
Filed: 1962-11-29
Abstract: Quinolinol esters are added to lubricating oils containing compounds of metals other than alkali metals to bind the metals as quinolinates. The preferred esters are those of 2-ethyl hexoic, myristic, palmitic, stearic and other higher fatty acids which are not subject to oxidation.  The amount of ester added is normally in the range 0.02-0.2% by weight of the oil.  The esters may also be added to coating compositions to combine with compounds of metals other than alkali metals to form a coating composition which is mildew-proof. In an example, aquinolinol ester is added to a wire-coating composition containing linseed oil, zinc oxide and rubber.ALSO:A quinolate (oxinate) of a metal other than an alkali metal is prepared by reacting an ester of a hydroxyquinoline in the absence of water with a compound of a metal other than an alkali metal. The reaction may be carried out in solution in an organic solvent at elevated temperature.  The esters used as starting materials are prepared by conventional methods. The acids from which the esters are formed may be a saturated or unsaturated mono- or polycarboxylic acid, e.g. formic, acetic, propionic, octoic, undecylic, lauric, myristic, palmitic, stearic, arachidic, undecylinic, oleic, linoleic, linolenic, palmitoleic, maleic, fumaric, succinic, glutaric, sebacic, phthalic, cinnamic, aconitic benzoic, phenylacetic, phenylpropionic, naphthenic, glycollic, citric, tartartaric, salicylic, and acetylsalicylic acid.  The acids may also be those derived from naturally occurring oils and fats. The metal compounds used may be the salts of those acids used to form the esters or of other organic or inorganic acids. The compounds may alternatively be enolates.  A mixture of compounds of different metals may be used.  Suitable metals for use in the formation of the quinolinolates are, e.g. aluminium, beryllium, magnesium, calcium, strontium, barium, lead, zinc, mercury, tin, iron, nickel, cobalt, manganese, chromium, copper, cadmium, silver and thallium.  The metals may be present in their higher or lower valency states where they have more than one valency state. The esters of substituted quinolinols, e.g. esters of 4 - methyl- 8 - hydroxy-; 4 - methyl - 2 - hydroxy-; 2-methyl-4-hydroxy-; 5,7-dichloro-8-hydroxy; 5,7-dibromo-8-hydroxy-; 5,7-diiodo-8-hydroxy-; 5-ethyl-7-bromo-8-hydroxy; 4-cyano-8-hydroxy-; 7-cyano-8-hydroxy- and 2-amino-8-hydroxy-quinolines may be used as starting materials although the preferred ester are those of 8-hydroxy-quinoline.ALSO:Metal quinolindates of metals other than alkali metals are used to treat fabrics, e.g. cotton, to make them mildew proof.  The fabric is treated with a mixture of a quinolester and a compound of the metal concerned in an organic solvent and the quinolinolate is formed in situ.  An example is given of the mildew proofing of cotton fabric by treating it with a solution of 8-quinolyl-2-ethyl-hexoate and copper octoate in mineral spirits thus depositing copper quinolinolate in the fabric.
