Title: Underwater arc welding process and apparatus
IPC: B23K9/00
Filed: 1968-02-05
Abstract: 1,213,203. Welding by fusion. KAKUMARU INDUSTRY CO. Ltd. 5 Feb., 1968 [14 June, 1967; 30 June, 1967], No. 5728/68. Heading B3R. In an underwater arc welding process welding is carried out in a compressed gas e.g. air, atmosphere the gas being passed from a supply source through a passage in an electrode holder and through a passage in a composite welding electrode to debouch at the welding tip thereof. The electrode (Fig. 8) comprises a rod 41 coated with a coating 42 and surrounded by a sheath 45 of an insulating tape e.g. a vinyl tape, which melts but does not burn at the temperature of the arc, the sheath being spaced from the rod by a helical aluminium wire or strip spacer 44 such that an annular gas conduit is defined between the rod and sheath. Plugs 46, 48 of strip aluminium and provided with apertures 47, 49 close the ends of the sheath and an uncoated portion of rod projects from the end of the sheath opposite the welding tip end. The uncoated portion and -the plug 46 enter into the electrode holder (Fig. 9, not shown). The plug 46 fits in a bore in an insulating retaining member (61) detachably secured to the rear portion of a conductive member (52). Mounted in the hollow rear portion of the conductive member (52) is a further conductive member (56) which receives the uncoated portion of the electrode rod and also has a gas passage (57) whereby gas entering the holder through a coupler (60) is passed to the welding rod. The conductive member (52) is a screw fit in a further part (51) to which a welding cable (53) is secured. The holder may be surrounded by phenol resin insulation. In a modification (Figs. 10, 11, not shown), the conductive member (52) comprises two parts pivoted together. For automatic underwater welding the electrode holder is mounted on a support (Fig. 3) which maintains an arc of constant length between the work and the tip of the electrode by varying the angle between the work and electrode as the latter is consumed. The electrode and holder are secured at 11 to a plate 9 pivoted at 10 such that (as shown in solid lines) the electrode is biased away from  the work due to pressure of a spring urged roller 16 tending to pivot the plate 9 clockwise. To bring the electrode adjacent the work a lever 19 secured to a shaft 17 to which an arm 18 carrying roller 16 is also secured is manually pulled in a clockwise direction. The roller urges a cam plate 15 slideable in a cylinder 12 to the right against spring pressure until the roller slips round a corner of the cam plate when the cam plate then jumps to the left. The roller then urges the cam plate in an anticlockwise direction (as shown in dotted lines) and the electrode is urged against the work. The support is magnetically held on the work by magnets 21, 21<SP>1</SP> when seam welding or, when fillet welding, by magnet 28 the magnets 21, 21<SP>1</SP> being removed.

Abstract: 1292358 Photographic dye developer transfer process EASTMAN KODAK CO 6 Feb 1970 [6 Feb 1969] 5770/70 Heading G2C A photographic dye-developer diffusion transfer process comprises exposing a photographic material comprising a support bearing a lightsensitive silver halide emulsion layer and comprising a dye developer in the emulsion layer or in an adjacent layer and developing the said material with an alkaline aqueous liquid that activates the dye-developer, the residual dye-developer being allowed to diffuse in register to a receiving layer, there being used an auxiliary developing agent which is a colourless catechol soluble in the alkaline aqueous liquid and being present in the material during said process metal ions which are chelatable by the catechol, the developing activity of the catechol being increased by the presence in the material during the development of a sequestering agent which is a stronger chelating agent for the metal ions than the catechol. The sequestering agent and/or the catechol may be in the material or in the alkaline aqueous liquid. The catechol and the sequestering agent may be present in the receiving material. The sequestering agent may be a non-polymeric tertiary amino compound having at least three carboxyalkyl groups or a salt of such compound e.g. ethylenediamine tetra-acetic acid or an alkali metal salt thereof. The catechol may have the formula:- wherein each R of R 1 -R 4  is H, OH, halogen, carboxy, aryloxy, alkyl, aryl or in which R 2  and R 3  or R 3  and R 4  taken together with the C atoms to which they are attached, and if the C atoms were joined by a single bond, represent the atoms necessary to form a cycloalkyl group, e.g. 4-phenylcatechol. The material preferably comprises red-,green- and blue-sensitive silver halide emulsion layers having associated therewith cyan, magenta and yellow dye-developers. Between the silver halide emulsion layers and their associated dye-developers sensitive to different regions of the spectrum there may be a stratum permeable to the alkaline aqueous liquid, comprising a water-insoluble polyvalent metal salt of a polymer which is film-forming, watersoluble and permeable to the alkaline aqueous liquid and which contains free carboxylic acid groups, the stratum being less permeable to a dye-developer in the alkaline aqueous liquid than a layer of the polymer itself, the polyvalent metal providing at least some of the metal ions. The stratum may comprise an alkaline earth metal salt e.g. calcium alginate. The metal ions may also be introduced into the material during washing operations in the preparation of the silver halide emulsions used.

Abstract: 751,635. Supplying liquid fuel to burners. LOOSER & CO., AKT.-GES., E. Feb. 27,1954 No. 5840/54. Class 75(1). Apparatus for burning heavy fuel oil comprises a burner including an atomizer 20, Fig. 1a, having an outer tube 19, to which oil is fed by a pump 1, arranged coaxially around an inner tube 21 connected with an oil preheater 8, Fig. 1b, a constriction behind the burner nozzle 3 being adapted to be opened or closed by a needle valve 37a controlling the oil flow to the nozzle, and ports 35 in the inner tube 21, directly behind the constriction, whereby oil pumped to the outer tube 19 recirculates to the heater via the inner tube 21 before and during operation of the burner. The fuel is fed through an inlet 33 to the preheater 8 by a pump (not shown) from a main tank, the preheater 8 containing electrical immersion heating elements 10 and a steam or hot water heating coil 9, thermostats 12, 13 and a float-operated level regulator 31 controlling the feed pump. When the fuel in the preheater 8 has reached a predetermined temperature the thermostat 12 energizes a motor driving the pump 1 which draws fuel from the preheater 8 and delivers it through a conduit 34 to the burner tube 19. The needle valve 37a is initially closed so that all the fuel returns to the preheater via the pipe 21, a conduit 38, a pressure governor 39 containing a diaphragm valve 40, and a conduit 22. The motor driving the pump 1 also drives a fan (not shown) supplying combustion air so that the combustion zone is purged with air and the fuel is preheated for a predetermined period before fuel is discharged from the nozzle 3. At the end of this predetermined period the needle valve 37a is opened by an electrically operated control device 36. An alternative apparatus is described in which an additional thermostat is disposed in the conduit connecting the pump with the outer burner pipe for completing the circuit to an electrical ignition device when the fuel in said conduit reaches a predetermined temperature, and for preventing recirculation of the oil so that the needle valve may be operated by the oil pressure within the inner burner pipe.

Title: Apparatus for indicating or measuring the flow of liquid through a conduit
IPC: G01F1/684
Filed: 1953-03-03
Abstract: 729,180. Measuring fluid How electrically. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 3, 1953 [March 5, 1952], No. 5852/53. Class 40(1). The invention relates to means for determinging the flow of liquid through a pipe 1 by measuring the amount of heat supplied electrically to a probe 6 disposed in the flow to keep a constant temperature different t between this probe and that of the liquid which is measured by an unheated probe 7, upstream of probe 6. The relationship between heating energy W supplied per unit time and liquid flow Q per unit time is shown in Fig. 2. The linear portion of the curve intersects the W axis at W 1  and, according to the invention, in order to get direct proportionality between the flow Q and the metered energy the portion W 1  of the heating energy W is not metered. The energy W 1  is supplied over a resistor 14 from the mains M independently of the watt-hour meter 9, which measures W-W 1 <SP>1</SP>, where W 1 <SP>1</SP> is the average value to which W 1 <SP>1</SP> falls when additional heating current is intermittently fed through a microswitch 13 automatically controlled by the temperature difference t. As shown, the microswitch is controlled by the fluid pressure difference in bellows 10, 11 responsive, respectively, to the probe temperatures, but thermocouples or temperature sensitive resistors may be used to regulate the flow of measured heat. The Specification explains that where the liquid flow does not fill the pipe 1, cylindrical or prismatic probes preferably extending vertically downwards for 0.8-0.9 of the pipe diameter are preferably used, in which case the meter readings are independent of the height of liquid in the pipe.
