Title: Improvements in filtering methods and apparatus
IPC: B01D25/00
Filed: 1932-01-15
Abstract: 394,042. Filters or strainers. THERMAL SYNDICATE, Ltd., Neptune Bank, Wallsend-on-Tyne, and MOORE, B., 41, Hawthorn Gardens, Monkseaton, Northumberland. Jan. 15, 1932, No. 1211. [Class 46.] A filter or strainer is formed by pressure of a hard narrow face or edge upon a yielding face or edge. As shown in Fig. 1, the open lower end of a tube A is pressed against an impermeable disc or washer C of paper, rubber, leather, soft metal, or the like on the closed lower end of a tube B. Liquid supplied to the interior of the tube A is filtered as it passes to an outlet D. Fig. 3 shows a modification in which the end of the tube takes the form of a cone. Figs. 5 and 8 show modifications in which a series of filtering passages are formed by the pressure of rigid rings A on impermeable yielding rings C. Fig. 9 shows an arrangement in which a number of elements formed in this way are supported between plates O, O<1> connected by bolts D in a casing L. Liquid from an inlet P passes through holes F to the interior of the elements and filters outward for discharge through an outlet K. Fig. 11 shows a filtering partition formed by placing a yielding apertured plate C between two rigid apertured plates A, A<1>, the apertures in the plate C registering with those in the plate A but being staggered with respect to those in the plate A<1>. Fig. 13 shows another form of apparatus in which an outer vessel A has grooves C on a tapered portion of its wall. In the vessel is placed a yielding sleeve D having slots or perforations in its wall which do not register with the grooves, and in the sleeve D is placed a hard plug F with grooves on its surface which register with the slots in the sleeve. Liquid supplied to the upper end of the vessel A passes through the grooves in the plug and the slots or perforations of the sleeve and filters through to the grooves C for discharge from the lower end of the vessel A. A modification is shown in Fig. 18 in which the plug F is omitted, the sleeve D is imperforate, and two series of grooves are formed on the wall of the vessel A, the liquid filtering from one series to the other. The apparatus is stated to be applicable for the removal of precipitates from salt solutions and of impurities from oils, water or mercury. According to the Provisional Specification the yielding faces or edges used in the apparatus may be of parchment.

Abstract: 699,255. Packaging. WHEELING STEEL CORPORATION. Jan. 17, 1951 [Jan. 17, 1950], No. 1298/51. Class 94(i) A method of packaging expanded metal lath comprises forming a pile of sheets of the lath, compressing the pile substantially perpendicular to the planes of the sheets throughout the area of the pile to consolidate the pile and promote nesting of the sheets and banding the pile to maintain the compression. Sheets of expanded metal lath are piled on a skid 2 which comprises two boards 3 laid upon and nailed to transverse supports 4. The pile on the skid is then lifted by an elevater truck and placed on the bed of a press, the truck is moved back and forth to agitate the pile and pressure is applied to compress it. Spreaders 10 are then laid transversely across the top of the pile and bands 13 disposed around it, passing over the members 4 and 10, and fastened.

A draw bolt comprises male and female members having co-operating formations 72 which can be inter-engaged by relative rotation of the members after one has been inserted within the other. A boring, milling and drilling machine has a saddle 26 with outboard guideways 32, a cross-slide 35, a tool storage drum 50, a tool-change shuttle in a structure 54, and a tool-change arm 52 for exchanging a tool in the spindle 45. A tool 57, Fig. 2, has a flange 61 to be gripped by the tool-change means, recesses 66 to receive driving dogs on the spindle, and a tapered shank 59 having an axial recess which has threaded lands to co-operate with the end of a draw-bar 70. A rotation of less than 45 degrees from the position illustrated in Fig. 10 is sufficient to lock the tool in the spindle. The draw-bar is rotated by springs moving a quick-pitch ball-nut, fixed against rotation, on a screw fixed to the draw-bar, the tool being released by fluid pressure means acting against the spring. The tool-change arm, having a pivoted gripping finger, delivers the tool in a certain angular position to the spindle which is itself located angularly by a fluid pressure operated plunger. The plunger 96, Fig. 6, is moved radially into a recess 94 in a spindle sleeve 92 when dogs 105 on the spindle engage positioning switches 106 while the pindle is being slowly rotated. The spindle 45 is advanced by fluid-pressure axially to pick up a tool and is then retracted to the operating position.

Title: Improvements in or relating to the hydrogenation of alkylanthraquinones
Inventor: JR WILLARD SHERMAN GLEASON
IPC: C01B15/023
Filed: 1956-01-16
Abstract: In the process of the parent Specification, wherein an alkylated anthraquinone is hydrogenated in solution in the presence of metallic palladium on activated alumina catalyst, and the alkylated anthrahydroquinone produced is oxidized to produce hydrogen peroxide and regenerate the alkylated anthraquinone, which is recycled to the hydrogenation, the water content of the mixture in the hydrogenator is maintained within the range corresponding with relative humidities in the gas phase of 40-98 per cent.  The anthraquinones may be 2-methyl-, 2-ethyl-, 2-n-propyl-, 2-iso-propyl-, 2-sec.-butyl-, 2-t-butyl-, 2-sec-amyl-, or 1,3-, 2,3-, 1,4-, or 2,7-dimethylanthraquinones and at least part of the anthraquinone may be the alkylated tetrahydroanthraquinone.  As described, 2-t-butyl anthraquinone in solution in methylnaphthalene and diisobutyl carbinol mixture is hydrogenated in the presence of the catalyst prepared as in the parent Specification, dried to a water content not exceeding that corresponding to a relative humidity of 60 per cent. The relative humidity of the incoming gas is adjusted by contact with pure water.  Nitrogen is passed through first to establish water equilibrium and hydrogen is then substituted therefor.  The hydrogenation may be effected at 0.4-3 atms. and 20-50 DEG  C. Specification 686,572 is referred to.

Title: Improvements in or relating to the production of selenium hexafluoride
Inventor: BANKS ARTHUR ASHTON
IPC: C01B19/00
Filed: 1952-01-23
Abstract: Selenium hexafluoride is produced by bringing fluorine into reaction with selenium at 250-350 DEG  C., condensing selenium tetrafluoride in the gaseous reaction products, returning condensed selenium tetrafluoride to the reaction zone, and recovering selenium hexafluoride in the uncondensed gaseous reaction products.  A mild steel or copper vessel having a fluorine and molten selenium inlet may be used, which is connected to a water cooled reflux condenser. Uncondensed gases may be scrubbed with 4 - 6 per cent. potassium hydroxide to purify the hexafluoride, which may then be passed through gel driers and compressed to a liquid.  In the example the hexafluoride is condensed in two traps cooled respectively with a mixture of solid carbon dioxide and trichloroethylene, and liquid air.
