Abstract: 1,248,545. Filters provided with equipment for backwashing. AMF CORP. 16 Jan., 1970 [7 Feb., 1969], No. 2171/70. Heading B1D. In a filter system comprising filter units 14, 14a immersed in a tank 10 for liquid to be filtered, and a tank 12 for filtered liquid, the liquid is filtered under sub-atmospheric pressure and the filter unit, when cleaning is required, is backwashed with filtrate under pressure, by means of eductor 26 and pump 16 associated with ducts and valves as shown. Pump 16 draws filtered liquid from tank 12 through duct 18 and discharges it through duct 20 and two-way valve 22 whence the liquid flows through one of two alternative paths. During a filtering operation, the filtered liquid flows from valve 22 through duct 24 to the inlet of eductor 26 and acts as operating fluid to draw dirty liquid from tank 10 through filter unit 14 (or 14a) and then through a throttle valve 38, duct 34 (or 34a), valve 30 and duct 32 into the eductor. When the filter unit requires cleaning, valve 22 is turned so that the filtered liquid discharged by pump 16 flows through duct 28, valve 30 and duct 34 (or 34a) to the filter unit. Valve 30 is a three-way valve so that either filter unit 14 or 14a may be isolated. In a modification (Fig. 4, not shown), the three-way valve 30 is replaced by a pair of two-way valves, Fig. 6 (not shown) illustrates a system wherein duct 28 is eliminated, but the outlet of the eductor is connected via a valve to the dirty liquid tank. Figs. 1 and 2 (not shown) illustrate a system having two filter units each comprising a number of separate fabriccovered plates or leaves (54), and wherein the dirty liquid tank (40) is equipped with a drag-flight. conveyor (46), driven by a motor, for removing debris from the bottom of the tank. The valves are normally power-operated and under the control of a programming device. The system may be used to filter the cooling liquid of a metal-working machine.

Title: An improved process for obtaining valuable hydrocarbon oils from unrefined hydrocarbon material by the action of high pressure hydrogen in the presence of a catalyst
IPC: C10G1/06
Filed: 1931-01-26
Abstract: In destructively hydrogenating carbonaceous materials or purifying oils by treatment with hydrogen, in the presence of catalysts subject to sulphur poisoning, the poisoned catalyst is removed at intervals and replaced by fresh.  The poisoned catalyst may be regenerated. Oil is mixed in a stirring vessel 3 with a catalyst and passed through a preheater 7 and heating coil 9 to a reaction vessel 11. Hydrogen may be passed in to the coil 9 or through the sprayer 14. Vaporous products are condensed in the usual manner and the hydrogen is purified and re-cycled.  Liquid is withdrawn by a pipe 24 and passed to a filter or other separator 27 which removes the catalyst and delivers it by means of a transporter A to a roasting furnace 31 where it is revivefied by oxidizing gases.  The purified catalyst passes to the mixer 3. Suitable catalysts are copper, zinc, nickel, iron, cobalt or their oxides.  Instead of roasting the catalyst, it may be dissolved in acids and <PICT:0377938/III/1> precipitated.  In an alternative process, the catalyst is used in fixed form in the reaction vessel; when it is poisoned, the flow of oil is diverted into a second chamber with fresh catalyst.  The catalyst may be regenerated in the first chamber without removal. The process is suitable for producing lubricating oils and purifying naphthas and kerosenes.

Title: Improvements in or relating to casting layers for the manufacture of films and sheets
Inventor: BISSCHOPS JOHAN HEINRICH
IPC: B29C48/08
Filed: 1966-01-21
Abstract: A casting layer for the manufacture of films; sheets is produced by coating a metal support with a solution of cellulose acetate, evaporating the solvent, hydrolysing the surface of the cellulose acetate, applying a solution in an organic solvent or in a mixture of water and water-miscible organic solvent of a Werner chromium complex salt in which a trivalent chromium atom is co-ordinated with a carboxylic acido group to form a coating of thickness 0.01 micron to 5 micron, and heating the coating to 50 DEG C.  The support may be a rotating metal drum or an endless metal belt forming part of a film casting machine.  Films and foils can be prepared by casting a film-forming solution, for example a solution of cellulose triacetate or other film-forming polymer.  Carboxylic acido groups mentioned are acrylic, methacrylic, stearic, palmitic, lauric acid, p-amino-benzoic, cyanoacetic, mercapto acetic acid, maleic acid, fluorinated aliphatic carboxylic acids.  The chromium complex salt composition may be applied by roll, dip, knife coating.  The chromium complex salt coating composition may be applied as a small strip to either side of the cellulose acetate surface when it is only intended to avoid the tearing of the film edges and when emhancing of the repellancy of the casting layer as a whole is not so important.  The casting layer may be used to form films of cellulose triacetate, polycarbonates, polyphenylene oxide, copolyesters of isophthalic acid, terephthalic acid and 2, 2-bis (4-hydroxyphenyl)-propane.
