Inventor: HENDERSON LESLIE
IPC: B23K9/028
Filed: 1965-08-09
Abstract: 1,142,198. Welding by fusion. CLARKE, CHAPMAN & CO. Ltd. 8 Nov., 1966 [9 Aug., 1965], No. 34082/65. Heading B3R. In apparatus for welding tubes end-to-end in which a welding gun 26 and a feeding device 34 for feeding welding wire through the gun are mounted to move round the tubes on a clamp 2 fixable to one of the tubes, the welding wire is fed axially into a curved section of the gun 26 which terminates in a nozzle 30 directed radially inward. Connected to the clamp 2 is a split support ring 10 having a hinge 12 and a looking device and rotatably carrying a drive ring 16 meshing with a worm 22. An inert gas shielded consumable or non-consumable electrode welding gun 26 is axially slidable in a sleeve on a bracket 28 adjustable radially on the drive ring 16. An annular gear 52 on the support ring 10 engages gearing actuating a cam 62 to reciprocate the gun 26 axially as the gun is moved round the tubes. By including a gear having missing teeth in the gearing, the gun 26 is caused to dwell at certain parts of its reciprocation. The gun comprises a feed motor 44 driving feed rolls pushing wire from a reel 40 through the gun 26. In apparatus for multi-pass welding, the gun is automatically moved radially at the end of each pass. In a modification, the support ring 10 is connected to two clamps 2, one for each of the tubes being welded.

Title: Improvements relating to recording apparatus
IPC: G01D9/26
Filed: 1935-12-09
Abstract: 470,390. Power factor measurements ; recording - apparatus. ALLGEMEINE ELEKTRICITATS-GES. Dec. 9, 1935, No. 34121. Convention date, Dec. 7, 1934. [Class 37] [Also in Group XIX] The relationship between two quantities is indicated on a strip which is moved past a marker at a speed dependent upon one of the quantities whilst the marker is operated at intervals dependent upon the other quantity. A record strip 13 is fed past a marker 11 which is energized periodically by impulses in a line 10 energized from a watt-hour-meter so that the marker is operated every time the watthours consumed increase by a predetermined amount. The winding disc 15 is operated through a ratchet-and-pawl mechanism advanced at intervals by impulses supplied to a relay 61<1> from a volt-ampere-hour meter 63. If desired, the marker 11 may also stamp the time of each marking on the strip. The distance between marks on the strip is a measure of the average power factor over the marking period. The relay 61<1> may be operated from a steam meter measuring the steam supplied to the prime mover of a generating system so that the resultant record indicates the average efficiency of the system. Specifications 532/14, 234,940, and 255,820, [all in Class 106 (iv)], are referred to. The Specification as open to inspection under Sect. 91 describes a counting arrangement in which the marked strip may be fed, at constant speed, past a photo-electric cell arrangement controlling a relay which operates on a clutch coupling a constant speed shaft with a spring-returned shaft on which are a number of discs with angularly spaced pins arranged, one on each disc, so as to operate separate counters. By this means the number of times the efficiency, power factor or other value reaches particular values is indicated on the counters. The mechanical operation of the counters may be replaced by electric control by arranging contact segments on the discs to transmit control impulses to the counting gear. This subjectmatter does not appear in the Specification as accepted.

Title: Process and composition for preserving standing poles
IPC: B27K3/14
Filed: 1936-12-14
Abstract: 486,791. Preserving wooden poles. SCHMITTUTZ, C. Dec. 14, 1936, No. 34287. Drawings to Specification. [Class 140] [Also in Group X] A process for preserving standing wooden poles comprises disposing on the top of the pole an aqueous tacky composition comprising a water-soluble wood preservative, coating an area of the pole at the ground line with an aqueous paste containing a similar preservative and enclosing the coated area in a spirally wound waterproof covering. The waterproof bandage may be of paper, leather, fabric or asbestos, waterproofed with tar, bitumen, paraffin or liquid petroleum. The composition applied to the top of the pole may be retained in position by nails or by an encircling metal flange provided with projections which are driven into the wood. Suitable water-soluble wood preservatives are sodium or potassium fluoride and zinc chloride, to which may be added copper sulphate, potassium sulphide, mercuric chloride, zinc fluosilicate, sodium or potassium arsenite or arsenate. Two or more substances which react to form insoluble compounds e.g. sodium or potassium dichromate and a fluoride or arsenate may be used. The composition preferably comprises also a waterinsoluble organic liquid such as dinitrophenol, dinitrocresol, tar oil or liquid petroleum, and a paste-forming ingredient such as starch, dextrine, glue, gelatine, casein, agar-agar or gum arabic. If desired hygroscopic substances such as glycerine, glycols or calcium chloride may be added to retard drying - out of the paste. Colouring and fireproofing agents may also be added. Preferably a mixture of substances having suitably different solubilities in water is used, for example the more easily soluble potassium arsenate or arsenite, potassium fluoride, sodium silicate, zinc chloride, sodium fluoride or copper sulphate may be mixed with the less soluble potassium dichromate, copper fluosilicate, potassium orthophosphate and mercuric chloride. In treating new poles preparatory to inserting them in the ground, the pole is de-barked from the butt up to a point above the ground line, the area at the ground line is coated with the paste and bandage and the butt coated with tar, bitumen, or wax.

Patent GB-483102-A (GB)
Title: Improvements in or relating to automatic centrifugal clutches
IPC: F16D43/12
Filed: 1936-12-15
Abstract: 483,102. Friction clutches. NEWTON, N. B. Dec. 15, 1936, No. 34398. [Class 80 (ii)] In a centrifugal friction clutch wherein centrifugal masses act on the presser plate through or against springs, the extension of which is limited, and wherein manual disengagement may be effected, means, separate from the manual disengaging means, are provided for voluntarily allowing the springs to extend further so as to cause clutch engagement below the critical speed. The masses 14 are movable against springs in radial guides in the driving flywheel 10, and act, through bell-crank levers 24 pivoted on the flywheel, on a plate b which acts on the presser plate a through interposed springs d<1> and which is normally retracted by springs 45. One end of each lever 24 slidably engages an aperture in the corresponding mass 14, while its other end acts on the plate b through an adjustable stud 28. Fibre plugs 21 on the masses cushion the inward movement of the latter. The presser plate can be retracted by radial levers 48 controlled by a pedalcontrolled sleeve 52, the levers co-operating with studs 46 secured to the plate a and being pivoted on a back plate c which is fixed to the flywheel by studs 31 fitted with spacing sleeves 32. The plate b slides on the studs 46. Studs e fixed to the plate a are secured to one end of flat blade springs g, the other end of which is secured to the plate c, so as to provide a driving connection between the plates a and c while allowing axial movement of the plate a. Centrifugal arms h, pivotally mounted on the plate b, are urged inwards by weak springs i and are capable of engaging behind collars f secured on the studs e within clearance holes in the plates band c. Normally, the arms h, are projected centrifugally outwards to the position shown in dotted lines in Fig. 7, in which they engage behind the collars f so as to limit the extension of the springs d<1>. In these circumstances, the clutch operates automatically while being capable of manual disengagement by operation of the sleeve 52. If, however, the flywheel is stationary or rotating very slowly, the arms h being still held in the dotted position by the friction between the arms and the collars ,f, and the sleeve 52 is operated so as further to withdraw the plate a, the friction is relieved and the springs i act to move the arms inwards into the position shown in full lines in Fig. 7. On releasing the sleeve 52, the springs d<1> can now extend beyond their previous limit, causing engagement of the clutch. As soon as the speed is sufficient, the arms h again move outwards and re-engage behind the collars f.

Abstract: 344,153. Regulating. LONDON GENERAL OMNIBUS CO., Ltd., 55, Broadway, Westminster, and WATSON, O. W. J., 10, Mortimer Road, West Ealing, London. Jan. 24, 1930, No. 2571. [Class 7 (vi).] Excess pressure on the throttle-operating pedal 10 causes the ignition to be retarded. The movement of the throttle-lever 12 is effected through link 17, lever 16 fast on the shaft 15, dog-clutch 19, 20, crank 21 and link 22. When the pedal 10 reaches the position 13 the adjustable set-screw 23 engages the bearing 24 and prevents further throttle opening. At the same time the tappet 18 engages the adjustable stop 30 and, as the pedal 10 is moved towards position 11, through crank 29 and link 28 retards the magneto interrupter. This further movement of the pedal 10 is effected against the action of springs 26, 37. During normal running the ignition lever occupies the position 34 ; for starting it is moved to position 33 and retards the interrupter through the dog-clutch 35, 36. The above device may be combined with a centrifugal control.

Title: Production of finely divided solid hydrolysis products of organosilanes
IPC: C08G77/00
Filed: 1958-10-29
Abstract: <PICT:0856522/IV(a)/1> Solid hydrolysis products are obtained from one or more liquid hydrolysable silanes, at least one silane containing at least one Si-bonded hydrocarbon radical, and water used in amount in excess of that stoichiometrically required for the hydrolysis of the silane(s), by finely spraying the silane(s) into a spacious reaction chamber so that the droplets fall freely into a mist layer produced by spraying the water into the chamber at a point or points below the silane inlet or inlets and recovering the product falling to the bottom of the reaction chamber.  In operation, the silane is sprayed downwardly from one or more binary nozzles (2), by means of air dried at (3) or an inert gas pumped into the nozzle, into a continuous zone of water mist obtained from water sprayed from flat-jet nozzles (4).  Gases leaving at (6) contain HCl (where chlorosilanes are used) and are free from Si compounds.  The particles of hydrolysate collect in sump (5) and are removed from the reaction vessel (1) by means of a siphon (7) after being suspended in water.  The process is applicable to silanes of the formula RSiX3, wherein R is an alkyl or aryl radical and X us preferably chlorine, alone or in admixture with other silanes, e.g. SiX4, HSiX3, R3SiX and R2SiX2, provided that the resulting hydrolysates are solids. Mixtures of 2 to 20 mols of SiX4 with 1 mol of R3SiX are preferred. The process is also applicable to the hydrolysis of diphenyldichlorosilane to give the corresponding diol. Specifications 659,022, 740,534 and 779,788 are referred to.ALSO:<PICT:0856522/III/1> An apparatus for the production of solid hydrolysis products comprises a spacious reaction vessel (1) fitted with one or more binary nozzles (2), through which the liquid hydrolysable material, e.g. silanes, is forced by means of air dried at (3) or an inert gas.  Flatjet nozzles (4), through which water is forced to provide a continuous zone of water mist, are so disposed at a distance below nozzles (2) to prevent any water from reaching nozzles (2).  The sump (5) into which the solid hydrolysate falls and collects is emptied by a siphon (7), and vent (6) allows gaseous reaction products to escape.  Specifications 659,022 and 740,534 are referred to.

Title: Optical system
IPC: G06V10/88
Filed: 1960-10-11
Abstract: 935,186. Spatial filters; photochromic material. NATIONAL CASH REGISTER CO. Oct. 11, 1960 [Oct. 12, 1959], No. 34776/60. Classes 97 (1) and 98 (2). A collimated visible light beam is diffracted by an object and focused on a filter which exhibits metachromism in response to radiation of which at least a major part of the spectrum lies outside the visible spectrum, means being provided for irradiating the filter with such radiation so as to modify the intensity of the visible light transmitted through the filter on to a light receiving device. In the system shown, visible light from screen S1 is collimated at L1 and focused by L2 on metachromic filter MCM2 so that on this filter is formed the image of source S1 as diffracted by an object OB (such as a transparency) which is imaged by L2 on a screen IPM. The image formed on IPM is modified by contracting the visible light transmissivity of the filter MCM2, this being done by irradiating selected areas of the filter with ultra-violet radiation from source S3 using a collimator L4 and semi-reflector BS1 and masks (not shown). The radiation from sources S1 and S2 are kept constant by radiation sampling and feed-back systems such as D1 and V.C.C. The filter MCM2 may be formed as a moving film or the metachromic material may be in film form deposited on slides or a long strip of quartz and be moved slowly or intermittently. Several examples of metachromic material are given. Specification 873,380 is referred to.
