Title: Membranes

Abstract: 1473857 Semi-permeable membranes RHONE-POULENC INDUSTRIES 3 Dec 1974 [4 Dec 1973] 52270/74 Heading B1X and B2E A semi-permeable composite membrane comprises a) a polymeric outer skin which is insoluble in water and active in reverse osmosis or gas permeation and b) an anisotropic ultrafiltration membrane which may be flat, tubular, spiral, conical or a solid or hollow cord, the polymer which forms the skin having a molecular weight sufficiently high as to allow the anisotropic ultrafiltration membrane to possess a degree of rejection of 100% with respect to solutions of this polymer and the outer skin a) being in contact with at least the less porous side of the anisotropic ultrafiltration membrane. An anisotropic ultrafiltration membrane is one which possesses a porosity gradient going from one surface to another. The outer skin preferably has a cut off zone of 500-10000 and a thickness of less than 1Á. The principal constituent of the anisotropic ultrafiltration membrane is preferably a complex polyelectrolyte derived from a polymer containing sulphonic acid groups and a polymer containing quaternary ammonium groups. A suitable polymer is the reaction product of a copolymer of acrylonitrile and methylallylsulphonic acid or a salt thereof and a copolymer of acrylonitrile and a quaternised vinyl pyridine. Many other suitable polymers are described. The polymer active in reverse osmosis may be a polyhydroxyether treated first with an epihalohydrin and then with a tertiary amine or a sulphonated polyarylether sulphone. The polymer active in gas permeation is a polyvinyltrialkylsilane, optionally chlorinated or sulphonated polyarylene oxides, polydimethylphenylene and diphenylphenylene oxides, polyether urethanes and polyamides. A reinforcement may be embedded in the anisotropic ultrafiltration membrane, e.g. a woven fabric, knitted fabric, a net or paper. Gases most frequently involved in gas permeation operations are O 2 , N 2 , H 2 , He, CO 2 , CO, CH 4  and H 2 S. The composite membranes may be prepared by coating an anisotropic ultrafiltration membrane with an organic solvent solution of a polymer active in reverse osmosis or gas permeation and evaporating the solvent. In the case of hyperfiltration membranes, partial evaporation is followed by coagulation in a non solvent, e.g. water. Coating (of one or both faces of the membrane) may be by dipping or passing the anisotropic membrane against a drum or roller partially immersed in the coating solution. Spraying, electrodeposition, electrostatic spraying and, in the cases of tubes, moving a cylindrical article through the tube pushing the solution to be deposited. The membranes may be used to fractionate sea water, brackish water, industrial effluent such as that from catalytic reactions or metal extraction, solutions of transition metals or heavy metals, sugars, enzymes, proteins, nucleic acids and other heat labile products. They may also be used to fractionate nutrient juices, fruit juices, meat juices, milk, whey, blood plasma, dialysis baths used in haemodialysis and ultrafiltrates from blood.

Abstract: 1,078,678. Rim rolling apparatus. ILLINOIS TOOL WORKS Inc. Dec. 30, 1964, No. 52847/64. Heading B5A. [Also in Divisions B6 and B8] In an apparatus for rolling rims on plastic containers, in which the rim is rolled by spirally grooved rotating rollers arranged around the periphery of the container (see Specification 951,242) the containers are fed in batches to the rollers by an accumulator mechanism which is responsive to the weight of the containers in each batch. In operation, freshly made containers are oriented and then blown through a tube 18 (see Fig. 1, not shown) to a tube 20 vertically disposed over said rollers, whence they are arrested by a counter-balanced lever 32. The lever is pivotable, through slots 28, 30 in tube 20, about pin 40 and when a sufficient number of containers have been arrested the weight of the batch thus formed pivots the lever downwards against the counterbalance 34 to allow further passage of the batch to the rollers, after which the lever returns to its raised position until another batch has been collected.

Abstract: 1397347 Determining solid content of liquids AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 14 Nov 1973 [15 Nov 1972] 52899/73 Headings G1W and G1X [Also in Division B1] Apparatus for determining the solids content of a liquid-solids mixture comprises a device for supplying filter papers sequentially to a receiving station where the individual papers are weighed and then arranged to receive a predetermined volume of the mixture before being dryed and weighed again, the weight values being computed by a device which indicates and records the value of solids content. As shown, filter papers 27 are picked up one-by-one from a storage container 6 by a sucker 26 which is rotated by a drive unit 7 to deposit such filter paper on a turn-table 21 above a hole 33 therein. A drive unit 13 rotates the turn-table to a weighing station where the turn-table descends to deposit the filter paper on to a weighing plate 9. After weighing, the turntable rises again to lift the filter paper from the weighing plate 9 and then rotates until the paper is located between two aligned filtration cylinders 11, 22. The drive unit 13 then lowers the upper cylinder 11 so that the filter paper becomes sandwiched between the cylinders 11, 22 before a predetermined volume of solids-liquid mixture is directed through a valve V 3  via the cylinder 11 to the filter paper. Subsequently the cylinders 11, 22 are moved apart so that the turn-table can be rotated to position the filter paper between two aligned drying cylinders 12, 23 where the filter paper is dried before being moved by the turn-table to the weighing station to be re-weighed. The filter paper is then lifted and directed by a device 28 to a disposal bin 20 simultaneously with the supply of a fresh filter paper from the storage container 6 by the sucker 26, the device 28 being driven by the same drive unit 7 as the sucker 26. A device 16 compares the weight values of each filter paper before and after the supply of mixture thereto to actuate an indicator 24 and recorder 17 accordingly. The predetermined volume of solidsliquid mixture may be obtained from a metering device 5 which is supplied with the mixture under investigation from a mixer 4 supplied by a tank 3 and sample reservoir 1.
