Title: Arc welding process and apparatus
IPC: B23K9/02
Filed: 1954-03-03
Abstract: 756,979. Welding by fusion. GRAVER TANK & MFG. CO., Inc. March 3, 1954 [May 29, 1953], No. 6253/54. Class 83 (4). In a submerged arc welding process for welding upwardly directed seams or horizontal seams on inclined plates in which pressure is applied to the weld seam to hold in place the molten flux and metal, surplus molten flux is allowed to escape from the seam. The welding apparatus is similar to that described in Specification 756,201 but the casing is provided with vents adjacent the arc and through which molten flux escapes. The welding tool T shown welding a vertical seam between upright plates S is manually or automatically propelled along a guide rail. The tool consists of a block 12 secured in a casing 11 carrying the welding electrode 47 and flux nozzle 41. The tool is supported against the plates S by rubber-tyred rollers 15 and the edges of the concave front of a spring- loaded shoe 17 mounted on pivots 18 in the casing 11. The rollers 15 drive a roller 26 which carries an endless belt 22 passing over the shoe 17 and supporting a resilient strip 20 of loosely felted glass wool bonded with plastic which is pressed by the shoe 17 against the weld seam immediately below the arc. The strip 20 traps a thin layer of solid flux between itself and the molten flux. Excess molten flux is expressed upwards and escapes through vents 21, the size of which can be altered by movement of plates 55, 57. The strip 20 may consist of two layers of glass wool bonded to each side of a strip of aluminium foil. When welding at the bottom of a narrow groove an additional rope-like strip may be interposed between the belt 22 and the strip 20. The flux nozzle 41 and shoe 17 may be of metal, carbon or ceramics, and instead of a metal electrode a carbon electrode may be used in conjunction with a filler wire. Two welding tools can be used on the same seam simultaneously from opposite sides. Specification 669,890 is referred to.

Title: Improvements in or relating to spark gaps
Inventor: FLETCHER GODFREY HERBERT
IPC: G01R13/42
Filed: 1951-03-15
Abstract: 704,980. Spark gaps. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 13, 1952 [March 15, 1951], No. 6292/51 Class 39(1) A spark gap for use in measuring the output voltages of magnetos and other sources of recurrent high voltage impulses comprises two main electrodes presenting between them a main open air gap and two auxiliary electrodes presenting between them an auxiliary open air gap at least one of said main electrodes being adjustable away from and towards the other, and said electrodes being so disposed that the auxiliary air gap is located to one side of the main air gap and symmetrically thereof when the main electrodes are close together. The arrangement shown comprises a fixed live electrode 11 and an earthed electrode 12 adjustable axially as indicated by the arrows. Two auxiliary electrodes 14 and 15 are supported by, or may be mounted in, a body 13 of high specific inductive capacity material in a position such that the auxiliary gap is substantially in line with the main gap when the main gap electrodes are close together. Electrode 14 is connected directly to the live main electrode 11 and electrode 15 is connected to earth through a high resistance 17, so that the same source of potential supplies both gaps. Alternatively, the auxiliary electrodes may be connected to a separate source which may supply an impulsive voltage similar to and in synchronism with that applied to the main electrodes or alternatively may supply a unidirectional voltage of sufficient magnitude to initiate and maintain a steady discharge across the auxiliary gap. Of the auxiliary and main gap electrodes at least one auxiliary electrode may be made of radio active material whereby the auxiliary and if desired the main air gap as well is in some degree self-ionizing, in which case the body 13 may be omitted.

Title: Improvements in typewriter key lever caps
IPC: B41J5/12
Filed: 1950-03-14
Abstract: 682,611. Typewriters &c. JARDINE, Ltd., J., and HARDY, F. S. March 14, 1951 [March 14, 1950], No. 6297/50. Class 100 (iv). A cap for a typewriter key is formed in plan with a straight front edge F and the sides D turned to the rear and connected to form a parabolic curve the vertex E of which is disposed at a higher level than the front edge and provides an upper surface to the cap which slopes, preferably concavely, from the back down towards the front. The cap is moulded or formed with a recess A to fit on the end of a key lever and with a rim H to form a recess to receive a transparent insert J to cover an identification character formed on the cap or on a printed slip. The base K of the recess is parallel to the upper surface of the cap so the insert when pressed into the recess assumes a concave shape and holds itself in position. The concave shape of the upper surfaces causes the finger to roll up the cap so that a uniform downward movement of the finger gradually increases the velocity imparted to the key-lever.

Title: Improvements in or relating to synthetic resinous compositions
IPC: C08G18/40
Filed: 1956-02-29
Abstract: A coating composition comprises a solution, in an organic solvent, of 100 parts by weight of a polyvinyl acetal and 18 to 400 parts by weight of a polyurethane of the formula <FORM:0808662/IV (a)/1> where R represents a phenylene, methyl phenylene, naphthylene or methyl naphthylene group, X represents a phenyl or alkylphenyl group, the alkyl group containing 1 to 6 carbon atoms, m is an integer greater than 1 but not greater than n, and n is an integer from 2 to 10. Such compositions, e.g. as films or castings, give a resinous composition on heating to above 150 DEG  C.  Similar compositions without the solvent may be used as moulding powders. Examples describe compositions comprising a polyvinyl formal resin having acetate, hydroxyl and formal groups and a polyurethane of the formula <FORM:0808662/IV (a)/2> where Y is a m-tolyl group (and, in one example, an adipic acid/ethylene glycol polyester) dissolved in high-solvency petroleum hydrocarbon (alkylbenzenes) and cresylic acid.  In comparison examples the polyurethane is omitted and in one example is replaced by a phenolformaldehyde resin.  The compositions are applied to copper wire and heated to 335 DEG  C., results of standard tests for enamelled wires being given.  The polyurethanes are obtained by reacting a polyhydric alcohol (such as ethylene glycol, propylene glycol, glycerol, trimethylol propane, pentaerythritol or a hexanetriol) with an equivalent amount of the reaction product of a monohydric phenol (such as phenol or alkylphenols, the alkyl groups containing 1 to 6 carbon atoms) with an appropriate arylene diisocyanate.  Other polyvinyl acetals which can be used are the reaction products of hydrolysed polyvinyl esters with acetaldehyde, propionaldehyde, butyraldehyde and benzaldehyde. The solvent may also comprise phenols, cresols and xylenols, with xylene or naphtha.  The compositions may also contain phenolic resins, polyesters, polyamides, fillers, pigment dyes and lubricants.

Patent GB-401298-A (GB)
Title: Improvements in or relating to the treatment of hydrocarbons
IPC: C10G17/06
Filed: 1932-03-04
Abstract: In a process for purifying hydrocarbons, sulphuric acid or similar reagent is agitated with the hydrocarbons to form a fine dispersion therein, the mixture is then allowed to age, during which impurities are removed by the acid and the dispersed particles agglomerate, and finally before deposition of sludge the agglomerated particles are removed by centrifugal treatment. Hydrocarbons derived from petroleum, or tar produced from lignite or coal, are violently agitated for 4 minutes with concentrated sulphuric to form a dispersion which is too fine to be separated in a centrifuge.  The mixture is then allowed to stand with mild agitation for 12 minutes, after which a small amount of water is added and the mixture is passed to a centrifuge.  In the mixing step the oil may be heated to 160 DEG  F. in the case of paraffin base oils, or to 120 DEG  F. for naphthenic oils.  The separated purified oil may be further treated with alkalies or decolorizing clay or may be submitted to de-waxing treatment, in which case the oil may be mixed with diluent before or after the purifying treatment. The sulphuric acid may be replaced by other refining agents such as stannous or aluminium chloride or mixtures of these with sulphuric acid.  A centrifuge such as that described in Specification 119,288, [Class 23, Centrifugal machines &c.], may be used at the separation stage, in which the desired hydrostatic balance of the liquid layers is obtained by adjusting the weirs controlling the discharges and if required feeding aqueous sulphuric acid with the mixture into the rotor.  The formation of a fine dispersion of the refining agent effects a rapid purification of the oil, and the separation of the agglomerated particles as soon as the mixture is centrifugable, prevents undesired reactions between the sludge and the purified oil.
