Title: Improvements relating to filters for petrol or similar liquids
IPC: B01D35/00
Filed: 1927-01-18
Abstract: 264,544. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalÚmit). Jan. 18, 1926, [Convention date]. Filters having sheet filtering-materials.-Filters for petrol &.c. comprising a filtering pocket of chamois leather, gauze, or like medium are provided with non-automatic means for forcing a reverse flow so that the medium is cleansed and the impurities discharged without the dismantling of the filter. Filtered liquid normally passes from the interior of a filtering pocket 13, Fig. 2, through a conduit 11. A reverse flow to detach the impurities collected on the pocket is obtained by pressing down a rod 7 to the lower end of which is fixed a flexible metal membrane 1. the periphery of which is held between the cap 2 of the filter vessel and a cover 3. The membrane is returned to its normal position by a spring 14, which may be situated as shown or below the membrane. In a modified form the rod 7 is omitted, and an upward extension of the membrane can be pressed down directly. The membrane may be replaced by a piston sliding in a cylinder. The impurities collecting at the bottom of the filter chamber may be discharged through an upwardly extending tube 21, Fig. 5. under the control of a needle valve 17. The valve housing is screwed into the cap 2 and can be removed as a unit with the valve and the tube 21. The outlet 18 for the impurities supports one end of a stirrup 23 which fixes the glass container 15 against the cap 2, the other end of the stirrup being secured between nuts 25. one of which screws on a tension screw 24 working in the cap 2.

Title: Improvements in or relating to apparatus suitable for the melt-spinning of syntheticlinear polymers
Inventor: SMITH FREDERICK ARTHUR
IPC: D01D4/00
Filed: 1954-01-20
Abstract: <PICT:0753670/IV(a)/1> <PICT:0753670/IV(a)/2> <PICT:0753670/IV(a)/3> <PICT:0753670/IV(a)/4> Apparatus for the melt-spinning of synthetic linear polymers comprises a melt chamber, a rotary metering pump and a detachable filter and spinneret assembly which can be camped to the pump to ensure a leak-proof joint.  The inlet and outlet ports of the pump are contained in different faces of the pump body, so that the filter-spinneret assembly may conveniently be clamped against the face which contains the outlet port.  The arrangement facilitates rapid changing of the filter-spinneret assembly, so preventing undue cooling of the pre-heated assembly and at the same time ensuring a good joint.  As shown in Figs. 1 (sectioned side elevation) and 2 (front elevation) a gear pump in housing 3 has an inlet port 15 for the molten polymer and an outlet port 17 communicating with a passage 25 in a plunger 23 which can move vertically in duct 21 and whose upper and lower ends both project from the pump body.  A combined filter and spinneret assembly 7 is inserted from beneath and locked in position by a partial turn, the assembly having radial projections 27, Fig. 3, which engage similarly spaced lugs 29.  After inserting the filter-spinneret assembly the plunger 23 is clamped down on to the washer 35 in the top of the assembly.  Clamping is effected by movement of the clamping bar 37, Fig. 2, pivoted at 39 and moved by rod 41 pneumatically.  In the embodiment shown in Fig. 4, the filter-spinneret assembly 7 has a projecting stem 43 and the assembly is raised into a recess in the machine frame with the stem 43 passing through a hole 53 so that a washer 47 recessed into a flat face of the stem 43 abuts against the outlet port of the pump 3, whereupon the nut 63 is rotated to pull down rod 61 and rotate lever 57 about its pivot 59 so that abutment 55 presses the stem 53 against the pump housing 3 to make a tight joint.  In this embodiment, the pump housing 3 bears against a fixed abutment 65 to resist the side thrusts exerted by the lever arrangement. Specifications 533,307, 536,379, 550,621 and 556,701, [both in Group XXVI], are referred to.

Title: Improvements in and relating to blow-off hose connections for tires
IPC: B60S5/04
Filed: 1920-01-20
Abstract: 138,089. Automatic Safety Tire Valve Corporation, (Assignees of Kahn, S.). Aug. 3, 1918, [Convention date]. Couplings, disconnectible; stuffing-box joints; with valves and cocks. - A connexion for tubes from compressed-air pumps or tanks to tyre nozzles is arranged so that the tyre is inflated to a predetermined pressure, and, in a modification, so that the coupling becomes disconnected on the attainment of such pressure. The first arrangement is shown in Fig. 1. The connexion to the tyre nozzle consists of a cylinder 46 surrounding the shank 37 which screws into the body 33. The shank 37 has a projecting flange 45, and a spring 48 is held between this and the upper flange 47 of the cylinder. A rubber thimble 49 is held in place by a cup 50. Above the cylinder is a cam-ring 52 fitting round the shank and having a handle 53. This ring has lifts 54, Fig. 4, which engage with lugs 55 on the body 33, and between the lifts depressions into which lugs 55 can project loosely. The cam-ring is turned into the position shown in Figs. 1 and 4 before the tyre nozzle is inserted, so as to compress the spring 48; but on its insertion, the ring is turned, as shown by the dotted lines in Fig. 4, releasing the spring, which expands the thimble 49 on to the nozzle. The whole connexion consists of a body 33 and head 24. The body contains a cavity 34 in which is a check valve 40 of which the stem fits loosely into the bore of the shank 37, and is unseated by the usual check-valve stem of the tyre nozzle. The head 24 contains a quill 12 round which is a spring 14 held between a blowoff valve 15 and pin 16, retained by an adjustable collar 19 graduated for pressures of 50 to 90 lb. Between the seating 17 of the valve and the portion of the head surrounding the jacket 23 is an annular chamber 31. The body and head are bored through at 44 to place this chamber in connexion with the bore of the shank 37. When the desired pressure in the tyre is attained, the valve 15 is unseated, and the hissing indicates this to the operator. In a modification, the spring 48 is adjusted for the required pressure and bears at one end against the flange 45, and at the other against a graduated nut screwing in the interior of the cylinder 46. On the attainment of the desired pressure, the device becomes disconnected. In a further modification shown in Fig. 7, the body 33' is elongated and takes the place of the shank. It contains a quill 12' surrounded by a spring 14<1> held at one end by a pin and graduated. collar as before and bearing at the other against a metal ring 63 supported on a washer 64. The packing 49a is surrounded by a metal thimble 49<b> having an inward flange 49<c> with notches 62. When the desired pressure is attained, washer 64 is lifted sufficiently to allow air to fill the entire space below the flange 45<a>, and so the spring 48 is compressed, as shown in the Figure, and the coupling released.

Abstract: 1,128,561. Preventing reboil in molten glass. CORNING GLASS WORKS. 17 Jan., 1966 [25 Jan., 1965], No. 2136/66. Heading C1M. A method of preventing the formation of gaseous bubbles in refined molten glass, caused by the development of a galvanic cell while the glass is covered by an atmosphere and is in contact with a vessel having electronic conducting properties comprises covering the cathodic portion of said galvanic cell with a non-oxidizing atmosphere. The method is particularly applicable to a continuous melting tank wherein the refining end has been lined to at or above the glass level with an electronic conductor, e.g. platinum, thus forming a platinum-glassatmosphere interface. However, it also applies where the conductor is placed in a position where a temperature gradient occurs in the glass and where a concentration cell of one particular component is created. The non-oxidizing atmosphere comprises nitrogen, argon or carbon dioxide, and this atmosphere is provided at the platinum-glass-atmosphere interface. Several glass compositions are given in the ranges in per cent by weight: SiO 2  57-80À5; Al 2 O 3  1-20; B 2 O 3  0-13; Na 2 O 1-13; K 2 O 0-8; CaO 0-11; MgO 0-9; PbO 0-29.
