Viscose is delivered by pipes 12, 13 to the sides of the nozzle 11 and flows upwardly between the domed upper walls 30 of the nozzle and the partitions 31 to the central upper part of the nozzle.  Air in the viscose separates into the chamber 18 at the upper part of the nozzle and the air free solution sinks from the opening 32 to the pouring slit 29.  The pipes 12, 13 fit into sleeves 15 of the nozzle 11 and serve therefore as trunnions about which the nozzle may be rocked.  The chamber 18 is provided with windows 26, and may be filled with an inert medium connecting the nozzle space with a pressure gauge 24 through a pipe 23 having a valve 22.  A pipe 20 with a valve 19 enables the pressure in the chamber 18 to be controlled.  The pressure gauge has a safety valve enabling excess pressure to be automatically relieved.  A cock 35 is provided in the lower part of the chamber 18.  Means are provided to enable the width of the slot, and also its shape to be varied to compensate for the varying degree of shrinkage over the width of the film.  One cheek 60, Fig. 5, of the pouring slit has a rib 67 in which screws 65 operate, said screws being rotatable by thumb wheels 66 and having at their ends heads 68 which rotate freely in recesses 69 in the movable lip 62 of the pouring slit.  Screws 73 pass through slots 74 in the lip 62 to fasten the lip in a desired position.  The opposite lip 63 has a flexible limb 78, the shape of which is adjusted by tension screws 84 and clamping screws 85 arranged alternately in the rib 82 opposite the limb 78.

Title: Improvements relating to fusion welding
IPC: B23K9/32
Filed: 1953-11-11
Abstract: 747,920. Welding by fusion. LINCOLN ELECTRIC CO. Nov. 11, 1953 [Nov. 12, 1952], No. 31308/53. Class 83 (4). [Also in Group XXX] In fusion welding apparatus including a hopper for granular flux having a nozzle through which flux can escape under gravity, means are provided for drawing air through the nozzle to prevent escape of flux therefrom. In one embodiment a welding head A, Fig. 1, is supported on a trolley B by a flexible tubular support 14. One or more electrodes 31 are fed from a reel 53 to the head through a conduit 50 within a corrugated hose 60 connected to a suction pump 61. The conduit 50 terminates in a nozzle 30, Fig. 2, located within a fibre suction nozzle 33 with a metal extension 39. A flux hopper 20 of larger diameter than the nozzle 33 and of reinforced corrugated tubing is secured at one end to the nozzle 33 and at the other end to funnel-shaped members 65 which are connected to the hose 60. A filter is arranged between the funnels and a butterfly valve 72 controlled by a solenoid is provided in the hose. In operation with the pump running and the valve open, the nozzle 33 is inserted in a flux container and flux is sucked up to fill the hopper. The flux is not carried beyond the hopper since in the enlargement provided by the funnels the air velocity is decreased and the flux grains fall back into the hopper. The head may now be moved to the workpiece, suction keeping the flux in the hopper. The valve 72 is closed and flux pours from the nozzle, the electrode feed is started and submerged arc welding is commenced. To remove unfused flux after welding the head, with suction applied, may be moved over the seam. The funnels may be replaced by a centrifugal separator, baffles, &c. In a modification, a tube 80, Fig. 5, branches from the hopper 20 at a point below the funnels and extends to a position level with the nozzle 33. In operation with the hopper filled, the valve 72 remains open and air is drawn through the branch to weaken the suction on the flux in the hopper which falls on to the work. Flux remaining on the seam is sucked up by the branch tube and returned to the hopper. When the hopper is empty the nozzle 33 and branch tube are placed in a flux container and when the hopper is filled the tube 80 is closed by hand or by a valve so that full suction is applied to the hopper to prevent escape of flux until the tube is opened. A suction head without an electrode fed therethrough, Fig. 6 (not shown), may be used with other torches. A non- portable apparatus includes a wheeled carriage movable along a track and supports a head comprising a large flux hopper through which is fed an electrode wire. Specification 648,638 is referred to.
