Title: Filtering assemblies
IPC: B01D35/12
Filed: 1972-07-03
Abstract: 1359387 Filtering and settling SEPARATION & RECOVERY SYSTEMS Inc 3 July 1972 [17 Dec 1971] 31073/72 Heading BID A settling/filtering apparatus removes solids from a fuel oil water mixture by filtration and then separating the oil and water by settling comprises two vessels 12, 62 arranged in series each separated by an internal wall into a lower inlet chamber 20, 66 and an upper filtering and outlet chamber 22, 68, each pair of two chambers being connected through tubular filter elements 44 releasably mounted against holes 34, 70 in the internal walls. The filter elements are held in place by pressure from above, a spider 50, mounted on a central threaded rod 48, having arms 50 which engage with springs (58, Fig. 3 not shown) attached to the tops of the filter elements. The upper chambers have water outlets 40, 72 and upper oil outlets connected to conduit 98. The outlet 40 from the first chamber 12 forms the inlet for the second chamber. In use, the crude mixture is pumped into chamber 20 by pump 24 through line 28. After separation of solids water containing a smaller amount of oil impurity is removed by outlet 36 and line 60. The oil outlet valve 100 is, however, kept closed so that oil collects in the upper part of chamber 22 so that the oil/ water interface 104 travels steadily downwards. The water product from the first vessel passes by line 60 into inlet compartment of the second vessel 62 and the filtration/separation is repeated therein with the result that pure water exits at 72. As in the first vessel water is removed (by line 76) whilst the oil collects in the upper part of chamber 68. When the oil water interface 104 in first vessel 12 reaches sensor 102, then the water outlet valve 78 is closed and oil outlet valve 100 is opened to remove the oil from the two vessels. After this has been done valve 100 is re-closed, valve 78 re-opened and the process repeated. Vessels 12 and 62 have gas escape vents 82 in their tops. The filter elements are suitably, formed of pleated paper having layers of fibre-glass wrapped thereround.
Patent GB-1044426-A (GB)
Title: A process for the manufacture of artificial leather and the products thus obtained
IPC: D06N3/12
Filed: 1965-07-21
Abstract: Artificial leather is produced by steeping a base layer of textile fibres in a solution of a polyamide in formic acid which contains 10-50% by weight based on the weight of the polyamide of a plasticizer for the polyamide and 30-200% by weight based on the weight of the polyamide of a solvent for the plasticizer, the solvent being miscible with formic acid and water, and then immersing the impregnated base layer in an aqueous medium to precipitate the polyamide on to the base layer.  Suitable plasticizers are 2-ethylhexane diol-1, 3, tetramethylene sulphone, N-ethyltoluenesulphonamide, dibutylmalate, butyl tartrate, tricresyl phosphate and dibutylphthalate and suitable solvents for the plasticizer are acetone, methanol and ethanol.  The base layer may be a napped, knitted or non-woven cotton or rayon fabric.  In order to prevent the polyamide from penetrating too deeply into the base layer it may be impregnated with an aqueous solution of lactic acid or urea and squeezed prior to treatment with the polyamide solution. Substances which protect the polyamide from degradation by light, oxygen and micro-organisms, e.g. manganous sulphate and cuprous thiocyanate may be added to the polyamide solution.  The aqueous medium used to precipitate the polyamide on to the base layer may comprise water alone or containing up to 20% by weight of formic acid or an aqueous solution containing an alkaline substance, e.g. sodium carbonate or hydroxide or ammonia, may be used.  The viscosity of the aqueous medium may be varied by the addition of sodium carboxymethylcellulose or polyvinyl alcohol.  The artificial leather may be used for use as lining material for shoes, as artificial wash leather or in the manufacture of gloves and artificial suede jackets.

Abstract: 386,742. Resistance coatings and deposits. FOWLER, L. J., 20B, Anerley Park, MUSGRAVE, J. L. and CRITTALL & CO., Ltd., R., 43, Bloomsbury Square, both in London. Nov. 11, 1931, No. 31212. [Class 37.] In an electric heating-apparatus in which the resistance consists of metal sprayed on to a base of refractory insulating material, the spray is moved along a predetermined path so that the metal is deposited upon the base in a zone of regular thickness and cross-sectional area. Alternatively the spray may be stationary and the base be moved. A layer of insulating material may be attached to one or both sides of the refractory base; and behind this a layer of heat-resisting material, or one layer may serve both purposes. Alternatively the base, after the resistance metal has been sprayed thereon, may be dipped in an insulating liquid which is then allowed to dry. For heating boilers, urns, &c., the resistance metal may be sprayed on the underside of the refractory insulating base, and covered with insulating heat-resisting material. The base may be arranged beneath the boiler &c. or may form the bottom thereof, in which case the upper surface may be sprayed with another metal or enamel. Alternatively the side of the base on which the resistance metal is sprayed may form the bottom of the vessel, in which case this side is also treated with a non-corrosive insulator or enamel. The invention is applicable to heating sterilizers, bronchitis kettles, glue-pots, sealing-wax heaters, coffee percolators, &c. For use in ovens, grills, hotplates, boiling tables, or toasters, the refractory base on which the resistance metal is sprayed may constitute a structural part of the article, or a separate unit. In the latter case, a layer of solid material may be interposed between the refractory base and the structural part to prevent unduly high temperatures. The heater may be used as a convection heater or as a heater in a trunk for a ventilation system. According to the Provisional Specification a stencil may be placed over the refractory base and metal sprayed over the stencil.
