Title: Improvements in inert gas shielded arc welding machines and in a method of welding
Inventor: GRAY THOMAS GILFILLAN FORREST
IPC: B23K9/028
Filed: 1965-01-19
Abstract: 1,065,217. Welding by fusion. BABCOCK & WILCOX Ltd. Jan. 19, 1966 [Jan. 19, 1965], No. 2396/65. Heading B3R. In welding a tube 7 to a tube plate 6, the tube 7 projecting a short way into a bore or counterbore in the plate 6, an inert gas shielded arc welding machine is located on the opposite side of the plate 6 to the tube 7 with a non- consumable electrode 43 rotatably mounted within the bore with its tip rotating in a plane spaced axially from the end of the tube 7 in a direction away from the tube 7. The counterbore or the tube end may be bevelled. The machine has a stepped cylindrical insulating bush 4 the small diameter part of which carries a metal sleeve 5 fitting within the bore and the large diameter part forming a platform 3 engaging the plate 6. A tungsten electrode 43 is secured by a grub screw in the end of a tubular holder 35 passing through the bush 4 and rotatably mounted in a frame 15 to which the bush is secured. A flexible drive 34 rotates a gear 27 secured to the holder 35. Current is supplied through a resiliently tensioned copper braided belt 19 secured to a terminal 26 and in sliding electrical contact with a grooved copper disc 17 hreaded on the holder 35. Argon from an inlet 45 passes through the holder 35 to an aperture 44 to surround the electrode 43 which is inclined or perpendicular to the holder 35. Argon is also supplied to the reverse side of the weld. Axial adjustment of the holder 35 and the electrode 43 is by rotating the holder 35 relative to the disc 17 by a graduated member 39, and the holder 35 is secured by a lock-nut 38. In a modification (Fig. 2, not shown) the holder (85) is mounted in a stainless steel sleeve (91) and is grooved to provide cooling water passages. The water inlet or outlet is connected to a water-cooled welding cable. In operation a locating sleeve is fitted in place of the tube and the electrode is axially adjusted until it contacts the sleeve whereupon an indicator lamp lights. The electrode is then retracted axially by means of the graduated member to achieve the required spacing when the tube is inserted. Welding is initiated by a high frequency current and is automatically controlled, e.g. by a cam rotating with the holder. The weld is effected in a number of revolutions with automatic variation of current and speed. The current is reduced gradually at the end of the weld. Full penetration welds leaving no crevice can be achieved. The supply is D.C. electrode negative. A spider mounted on the machine may be secured mechanically or magnetically to the tube plate. A mercury bath type current connection between the fixed and moving parts of the machine may be used in place of the described connection.

Title: Method and apparatus for the logarithmic counting of pulses
IPC: G06M3/00
Filed: 1974-01-18
Abstract: 1459867 Counting apparatus; Iogarithmic conversion HEWLETT-PACKARD Ltd 18 Jan 1974 02481/74 Heading G4D [Also in Division H3] In order to derive a value proportional to the logarithm of the total number of incoming pulses, a first counter 10 counts the pulses and issues a pulse to increment a second counter each time the count in the first counter reaches a value x<SP>1</SP>=x+kx, where x is the last value at which the second counter was incremented and k is a constant multiplier. In Fig. 2 the counter 10 is a binary counter and the multiplier k is a power of two whereby the increment #x (=kx) is determined by shifting the digits of the total count in counter 10. The first value x 1  is determined arbitrarily by a control circuit 14. When counter 10 reaches x 1  a down counter 12 is loaded with a shifted version of x 1  and subsequent incoming pulses are counted up in counter 10 and down in counter 12. When counter 12 reaches zero a pulse is issued to increment counter 16 by a constant value #y and counter 12 is reloaded with the new value of kx and this is repeated again and again for a time detertermined by the control 14. The value in counter 16 is the required logarithm; #y is determined according to the base of the logarithm. A suggested application (Fig. 4, not shown) is to the digital measurement of a signal to be expressed in decibels : the signal is applied to a squaring device, e.g. employing a thermocouple, and thence to a voltge controlled oscillator which thus delivers a frequency proportional to the power of the signal to the above counting apparatus.

Title: Improvements in or relating to processes for the production of shaped articles of graphite and/or other carbon
IPC: C04B35/52
Filed: 1955-01-27
Abstract: Shaped articles of graphite and/or other carbon are prepared from a mixture containing a semi-coke of petroleum or pitch comprising 5 to 25 per cent by weight of volatile constituents and an emulsion consisting of or containing a mixture of pitch or tar with either water or an aqueous protective colloid solution.  A wetting agent such as a non-ionic polyglycol-ether derivative may be added to the emulsion.  The protective colloid may consist of cellulose glycollate, carob bean flour, tragacanth, casein, starch, dextrin, agar-agar, size, bile acid, or gelatine.  The green bonding strength of the moulded element may be increased by adding to the mixture 0,5 to 5 per cent by weight of flowers of sulphur, or powdered or colloidally precipitated sulphur.  To the semi-coke may be added up to 40 per cent by weight of calcined coke, graphite, or carbon black. In one of the described examples 750 grams of petroleum semi-coke with 10,5 per cent volatile constituents, and with a grain size of 300 to 2,500 microns, are mixed at a temperature of 30 DEG C. with 250 grams of cellulose glycollate-pitch emulsion (20 parts by weight of 2 per cent aqueous cellulose glycollate solution and 80 parts by weight of a mixture of 3 parts soft pitch and 1 part anthracene oil, and containing 0,5 per cent by weight of a wetting agent, e.g. a dodecyl phenol-ethylene oxide condensation product).  The mixture is shaped and baked with exclusion of oxygen, and, if desired, graphitized in the same or a separate furnace.

In a method of cleaning gas swept surfaces of heatexchangers whilst in operation by dropping cleaning elements therethrough as described in the parent Specification, the velocity of the flue gases leaving the heatexchanger is increased or otherwise maintained by a baffle device or devices so that the soot and dust particles remain in suspension in the gases and are removed whilst the cleaning elements drop out of the gas flow. As shown, the flue gases move downwardly through the heat-exchanger 1, past the baffle 2 which causes a choking effect and therefore increases their speed, and leave from the lateral outlet 21, taking the soot and dust particles with them. The cleaning elements drop into the hopper 11 and are removed by the air-flow conduit 12. The baffle is preferably parallel to the side 13, and the side 14 inclined at such an angle that the elements do not rebound into the outlet 21 but on to the side 13 and then fall to conduit 12. Specification 698,103, [Group II], is referred to.

Abstract: 451,180. Treating foul liquids. COUTTS & CO., 440, Strand, London, and JOHNSON, F., 218, Victoria Drive, Eastbourne, [Representatives of JOHNSON, J. Y.].-(I. G. Farbenindustrie Akt.-Ges.; Frankfort-on-Main, Germany) Jan. 30, 1935, No. 3072. [Class 111] To remove phenol from waste aqueous liquid the liquid is treated with a combustion gas, which has been utilized for drying materials containing water, for example raw brown coal. Sulphur dioxide may be added to the combustion gas. The liquid is preferably heated to a temperature near or above the dew-point of the gas. For treatment, the aqueous liquor may be added to an aqueous liquor from which phenols have already been removed and which is being circulated in the apparatus in a heated condition. As shown in the Figure, the liquor containing phenol supplied at E1 is passed by a pump P through a pipe u1 into the tower T1 and is treated by gas which has already passed through a tower T2. The pump P also draws a portion of the treated liquor from the bottom of the tower T1. The rest of the treated liquor passes through a pipe E2 to a pump P1 which forces it with some of the liquor from the bottom of the tower T2 to the top of the tower T2. The rest of the liquor from the bottom of the tower T2 is discharged from the apparatus at A.

[Class 100 (ii).] A printing-device, which is adapted to be run through an addressing-machine and to be stored in classified order, comprises a printing-plate and a record card adapted for interlocking engagement so as to lie edge to edge in the same plane. As shown in Figs. 2 and 8, the side edges of a sheet-metal address-plate 1 are depressed and turned in to form V-shaped flanges 3, and a similar flange 8, formed at the back of a metal strip 6 fixed by prongs 7 to a record card 5, is engaged with the top flange 3, which is cut away at the ends 4. A slot 9 is formed near one end of the flange 8, and the remaining part of the flange is flattened to form a stop 10 adapted to abut against the left end of the flange 3 when the card is in position. The opposite end of the flange 8 is slotted and flattened or is slit and flattened to form a stop 12 to engage the right end of the flange 3. The part 11 cut to form the slot 9 is bent over to assist in securing the card 5, as this corner must be deflected slightly to allow the flange 8 to engage with the flange 3 in attaching the card and to disengage the stop 10 when removing the card. In a modification, Fig. 15, an address-plate 16 is provided with rear flanges 15, and a flange 17 is formed on the front of a connecting-strip 22. One end of the top flange 15 is slit and flattened at 20, and a slot 23 is formed near one end of the flange 17, so that when the flanges are interlocked the part 22 of the flange engages behind the end of the flange 15.

Filed: 1942-03-09
Abstract: 556,610. Valve gear. BUCKLEY, A. B. March 9,1942, Nos. 3094 and 4059. [Class 7 (vi)] [Also in Group XXIV] A valve tappet or the like with hydraulic means for taking up clearance comprises a piston portion 36, 38 operating in a cylinder portion 28, 30 so as to confine a body of liquid in the space 48 between them, the liquid being supplied to this space past a ball valve 60 and through a port 64 continuously open to an annular recess 66 between the part 30 and a surrounding guide 22, and the port 64 being supplied from a pressure line 78 fitted with a relief valve 114 affording a restricted escape of liquid adjustable by a screw 119. When the tappet is operated by its cam 34 to open the valve 42, the liquid leaks between the piston and cylinder to a space 70 which communicates with the recess 66, port 64, and valve 114 by a passage 68. A pressure chamber 98 containing air is fitted to the line 78 to absorb sudden changes, and oil or other liquid is supplied by a pump past a valve 106. Packing-rings 84, 86 prevent the entry of air to the tappet. For starting the engine, a valve 124 is lifted_ by means of a lever 130 and pusher 138, to admit additional liquid from a tank 120. The lever 130 may be connected by a spring 132 to the push-button of the starter motor. In a modification the tappet may be slightly inclined from the horizontal so that the ball valve 60 is closed by gravity, and a spring is arranged between the piston and cylinder portions of the tappet, to assist the liquid in separating them. In another form, Fig. 3, the liquid is supplied from the line 78 to the tappet past an arcuate leaf-spring valve 229, and the leakage collecting in the space 186 when the tappet is operated is brought intermittently into communication, with an outlet 240 controlled by a ball valve 244, the spring of which, is adjusted by a screw 248. In other forms the valve controlling the admission of liquid to the tappet, either of ball or leaf form, also serves to control the escape of the leakage between piston and cylinder. Specification 540,083 is referred to.

Abstract: 113,812. Hutchins, T. W. S. March 2, 1917. Carbon pipes.-Carbon in the form of blocks, rods, tubes, &c. for electro-chemical, metallurgical, &c., purposes, is prepared by carbonizing pitch such as that obtained from producer-gas plants, tar, or a mixture, to which may be added ground coke, coal, or retort carbon, in heated tubes of a material such as fire-clay, which contracts on cooling to a less extent than does the carbon block which is produced. The material to be carbonized is fed by a rotary valve f from a hopper e into a fire-clay tube a heated by a combustible mixture admitted at b to a combustion space c. The volatile matters evolved during carbonization are withdrawn by pipes g, h, the flow from which may be restricted, so as to obtain pressure in the tube a or so as to cause the volatile matters to pass downwards through the carbon. The carbon block produced is withdrawn after cooling through a door i. To produce carbon tubes, the carbonization is carried out in the annular space between two concentric tubes or between a tube and a rod.

Title: Method of and apparatus for a uniform electrolytic internal chromium plating of tubes
Inventor: LICHARZ CARL ELMAR
IPC: C25D7/04
Filed: 1951-02-08
Abstract: 712,314. Electro-plating. ELECTRO METAL HARDENING CO. SOC. ANON. Feb. 7, 1952, [Feb. 8, 1951.] No. 3114/51. Class 41. In the internal chromium-plating of a rifled tube an anode is employed, the cross-sectional cenfiguration of which is the inverse counterpart of the rifling of the tube, and the tube is rotated relatively to the anode. Both the tube and the anode may be rotated, the rotations being at different speeds or in opposite directions. The velocity of rotation may be non- uniform, e.g. the rotation may be interrupted and resumed one or more times during each complete revolution. Interruption or retardation of the rotation may be effected at times when portions of the inner tube surface which would otherwise be less intensely plated are positioned closest to the anode; the interruptions or retardations may also be timed to produce a reinforced coating at desired portions. As shown the rifled gun barrel 4 is mounted between, and the anode 6 is mounted in, fitting elements 8, 10; the rifled formation of barrel and anode is not shown. Electrolyte is supplied to the barrel by conduit 12 and leaves by conduit 14. The upper element 10 is rotatably mounted in a container 2 and is driven by means of a cog-wheel 26. The lower member 8 is fixedly mounted in the container and is provided with a rotatable bushing 24 in which the lower end of the barrel 4 is supported. Ball bearings 20, 22 are provided in the container 2. The outer surface of the bushing is provided with a helical thread of considerable pitch, this tending to press down electrolyte which would otherwise leak upwardly. Electrolyte from the barrel discharges at the top into an annular groove in the fitting 10 and thence to the outlet 14. The outer surface of the element 10 is provided with helical grooves on either side of the annular groove to prevent leakage. Any electrolyte which may leak into the container 2 is discharged by conduit 16. The upper anode terminal 7 may be swung away to permit the anode to be inserted in or removed from the container.
