Title: Filter method and apparatus
IPC: B01D24/48
Filed: 1964-09-22
Abstract: 1,075,863. Back washing filter beds. UNION TANK CAR CO. Sept. 22, 1964 [Oct. 30, 1963], No. 38689/64. Heading BID. To avoid loss of filter media 12 during a gas cleaning cycle prior to backwashing with a store of filtered liquid 20, air is entrained during normal filtering in the unfiltered liquid prior to it entering the filter chamber 18 containing the bed of filter media 12 so that entrained air is released and forms a gas space 26 above the filter bed, the filter media carried by the cleaning gas disengaging from the gas and falling back on the filter when it contacts the gas space. The air may be entrained in the liquid in an inlet head box 38 by causing the liquid to cascade over a weir 40 before passing through pipes 36 and 30 to the filter chamber. Alternatively a pump with a shifter valve, or an air bleed line in the pipes may cause the liquid to have entrained air. An outlet riser pipe 48 communicates with the bottom of the liquid storing chamber and also with a service pipe 50 which controls the level of the store of liquid. When the filter bed has become clogged the liquid rises in a pipe 54 containing a sensing switch 56 and probe 58. The switch in turn actuates an electrical control 60 which closes a valve 62 in a liquid draw line 34 and slowly opens a valve 74 in an air supply pipe 76 and also slowly closes a valve 70 in the riser pipe 48. Air then passes up through the bed to dislodge any foreign matter, passing out of the chamber through conduit 30 and a vent tube 75 which normally controls the level of the gase space. After a predetermined period of time, a time switch 72 causes valve 74 to close and the valve 70 to open so initiating the backwashing. When the level of the liquid store is such that it is beneath a probe 68 a switch is actuated which in turn actuates control 60 which closes valve 62, and the normal filtering restarts. A baffle 32 helps in distributing the unfiltered liquid and in settling out the filter media in the cleaning gas.

Title: Extrusion Apparatus
Inventor: DERIDDER ERNST J
IPC: B21C23/20
Filed: 1968-08-13
Abstract: 1,174,027. Extruding. REYNOLDS METALS CO. 13 Aug., 1968 [29 Aug., 1967], No. 38735/68. Heading B3P. An extrusion apparatus comprises a die 29 in a container 23 against the forward end of a billet 28 and a cross-head 24 which serves to close the rear end of the container and to move the container towards a stationary ram 22 whereby the die is forced through the container and the billet extruded through the die. A die receiver 52 is positioned at the rear of the container after extrusion to receive the die and convey it to the front end for extrusion of another billet. The cross-head 24 is moved by an hydraulic or pneumatic piston-cylinder assembly 30, 31 and retracted by pistoncylinder assemblies 34-36. Alternatively the cross-head may be moved by a cam or other mechanical or electrical means. The container is moved relative to the apparatus frame 21 by piston-cylinder assemblies 38-40 which serve to keep the rear of the container biased against the cross-head during extrusion. After extrusion the cross-head is retracted and the die receiver 52 moved to a position coaxial with the container bore. The container is then moved in the extrusion direction so that the die is moved into the receiver bore 53 and clamped. A cutting saw 62, Fig. 5 (not shown), is then moved on a slide 70 by fluid pressure to separate the extruded product 51 from the die. The die-holder 52 is then retracted to a die cleaning position where a blade 82 cuts-off the discard butt (54), Fig. 5 (not shown), and the tongs 85 are moved to remove the remaining discard. A new billet 28A is then moved by a slide 73 to the rear of the container and moved into the container as it is retracted towards the cross-head 24. The die receiver slide 79 can now move the cleaned die 29 to the front of the container, Fig. 7 (not shown), and it is pushed therein by a fluid-operated inserter 65. The inserter 65 is held out of the extrusion axis by a roller and latched relative to the diereceiver slide. The cross-head 24 may have a mandrel secured thereto for tube extrusion. The die is mounted in a holder with ribbed sides 114 to prevent undue wear on the container. The die member can be readily replaced by different die members. Further, the dieholder is relatively inexpensive and easily replaced.

Abstract: 1,191,223. Ion pumps. VARIAN ASSOCIATES. 20 Aug., 1968 [23 Aug., 1967], No. 39741/68. Heading H1D. In a getter ion pump comprising an anode structure 4 having at least one discharge passageway traversed by a magnetic field B and insulated by a structure 13 from a cathode structure 5, a projection 6 of getter material extending from the cathode 5 into the passageway terminates substantially less than halfway along said passageway, thus forming a magnetron discharge zone 16 and a Penning discharge zone 18. Material sputtered from the projections 6 forms annular deposits 19 on the cathodes 5, thus improving the pumping of noble gases. The insulator 13, e.g. of alumina ceramic, is protected by an annular sputter shield 15 mounted on the anode support rod 9. The cathode plates 5 may be of Ti and the projections 6 of Zr, Mo or Ta to give increased sputtering. The projections 6 may be conical (Fig. 2, not shown), and a single projection extending into one end of the passageway may be used. A plurality of projections may be formed by folding a serrated metal sheet which is associated with a multi-cellular anode (Figs. 4 or 5, not shown). The projections 6 may be integral with the cathode plate 5 or may be insulated therefrom (Fig. 6, not shown) to enable the projections to be held at a lower potential than the cathode, thus providing a triode arrangement with reduced re-sputtering of the deposits 19.

Abstract: 1,035,471. Hot stretching polyolefine filaments. COURTAULDS Ltd. Nov. 7, 1962 [Nov. 8, 1961], No. 39941/61. Heading B5B. The tenacity of a polyolefine filament, particularly a polypropylene filament containing a major proportion of isotactic polypropylene, is increased by stretching it while it is passing through a zone of a gas which is at a temperature above the melting point of the polyolefine, the filament being in contact only with the gas in the zone, and the conditions employed being such that the degree of opacity of the filament material is not substantially increased by the process. The gas normally used is air and may be at a temperature of 180-300‹ C. and the draw ratio may be 8 to 13. The stretching may be carried out in a single zone or in two successive zones each containing a gas which is above the melting point of the polyolefine. The conditions of heating and stretching are such that the stretched filament is bright and of uniform denier. The upper limit of the draw ratios is about 14: 1. The gas may be contained in an electrically heated metal box the closed ends of which have slots to allow the passage of the filament.
