Filed: 1975-09-18
Abstract: 1479258 Potato extruder AMERICAN POTATO CO 18 Sept 1975 [19 Sept 1974] 38430/75 Heading B5A An extrusion machine for shaping rehydrated potato agglomerates comprises a cylinder 14, which initially is positioned over piston 22 (Fig. 2), via mounting 95, but in use is mounted as in Fig. 1 by means of lugs and slots 32 and 34 (Fig. 4) with piston 22 mounted on operating rod 24. Dehydrated potato and water is injected through opening 20 and is then extruded through dough forming element 38 comprising longitudinal strands of triangular section 4, 8 preferably made of nylon or other thermoplastic material. Dough extruded from the chamber is separated from the forming element by separating arm 39 which moves backwards and forwards across the exterior of the dividing structure. The piston 22, which is preferably constructed of nylon, has a thin lip 74 which is flexible enough to achieve a water tight seal. A flexible diaphragm 80 rests against the planar face 78 of the piston, secured by means situated off the centreline of the cylinder, so that in use as the piston is withdrawn from the dough after extrusion the lower portion of the diaphragm 80 pulls away from piston surface 78, thereby to admit air to the space formed between dough and piston to so prevent formation of a vacuum and consequent disruption of the remaining dough plug in the cylinder.

Filed: 1960-11-09
Abstract: 991,164. Brazing. C. H. JOHNSTON & SONS Ltd., and F. C. RAY. Nov. 6, 1961 [Nov. 9, 1960], No. 38459/60. Heading B3R. A method of making a seam in a woven wire mesh comprises weaving or otherwise applying a strand of a brazing medium to the mesh adjacent to one of the edges to be joined, overlapping said edges and applying heat and pressure to the region of the edges to cause fusion of the brazing medium and effect jointing of the edges. One weft strand is removed from each end of a cut length of woven wire mesh 5 and at one end is replaced by a strand of brazing material 7, e.g. silver solder, which may be wire cored, in which case the core wire has a melting point in excess of the brazing temperature. The ends 8, 9 of the warp strands 6, 11 of the mesh are brought together about a cylindrical mould 10, a steel support strip 13 is placed under the overlapped ends and an electrical hard welding device 14 comprising a suitably mounted rubber wheel 19 and a conductive wheel 20 of copper or carbon used to heat the silver solder and press the ends together into linear alignment, Fig. 3. Alternatively, a welding torch is used to heat the solder and the device 14 used as a pressure roller only. Additional strengthening strips of silver solder may be fused along the joint. In a modification, the ends of the warp strands 6<SP>1</SP>, 11<SP>1</SP>, Fig. 4 (not shown), may be staggered prior to brazing or alternatively the brazing material may be applied as a ribbon to one surface of the mesh.

Fluid is supplied by an hydraulic pump 18 connected to a by-pass valve 20, and enters valve 12 at port 38; which valve also includes an exhaust port 40, two control ports 34, 36, and two work ports 30, 32, and is adapted to be moved to a position 44 for supplying fluid through passages 80, 92 so that chamber 52 is supplied, or moved to position 46, whereupon fluid is supplied to chamber 50 of the motor, or moved into position 42, whereupon piston 112 is seated and piston 48 of the motor is locked. Cavitation tends to occur in chamber 50 due to the arms 16 tending to pull piston 48 at a speed greater than that produced by the pressure in chamber 50, and this is prevented by controlling the flow from chamber 52 through valve 10. A metering slot 148 is provided in seat 140.

Filed: 1963-10-08
Abstract: In manufacture of a matrix for a channel intensifier device of the kind described in Specifications 1,064,073 and 1,064,074, a number of rods are assembled in a bundle and sealed together along spaced generatrices to form a rigid channelled block in which the channels are constituted by interstices between adjacent rods. The rods may be glass of circular, square, star - shaped or semi - tubular cross-section, and may be fine fibres packed into a jig with the aid of vibration, or wound into a hank from which channelled blocks are sliced after sealing.  Alternatively, a primary bundle may be foamed from a small number of rods of relatively large section held in a regular array in a jig during sealing, and subsequently drawn down. Such a primary bundle should have a regular overall cross-section so that it may be sealed to similar bundles with no major gaps between. A secondary bundle formed in this way may be further drawn down and sliced to form the finished matrix.  Sealing may be effected by heating to cause softening of the rods, or of a low-melting-point glaze coating on the rods.
