IPC: B01D67/00
Filed: 1971-02-18
Abstract: 1396091 Semipermeable membranes BABCOCK & WILCOX Ltd 18 Feb 1972 [18 Feb 1971] 4897/71 Heading B5B [Also in Division B1] Semipermeable membranes are made from a copolymer prepared from a monomer of a substituted or unsubstituted vinyl type having the formula and of hydrophilic properties and a similar compound but of hydrophobic properties. The proportions and properties of the monomers are sufficiently balanced for the copolymer to be insoluble in, but able to absorb, water. The copolymer is dissolved in an organic polar solvent which readily dissolves it and which has a relatively low vapour pressure (as herein defined), the solution is cast into a film, solvent is evaporated from it, and the film is then treated with water for at least 10 minutes. The preferred hydrophilic monomers are styrene, methyl methacrylate and acrylonitrile; the preferred hydrophilic monomers are acrylic acid and methacrylic acid. The solvents used in the exemplified processes are dimethylformamide, dimethylsulphoxide, dimethylacetamide and triethylphosphate. Optionally, an additional solvent or cosolvent is added to the solution. Such liquids are water, acetone, methyl ethyl ketone and benzene. Addition of these gives a membrane of porosity such that macromolecules do not pass across it but smaller molecules do. If membranes able to reject salts are required these additional liquids are not added.

Title: Procedure for the registering of information on register cards and for the reading of the registered information and an apparatus for such reading
Filed: 1960-02-11
Abstract: 902,897. Sensing record cards. SVENSKA DATAREGISTER A.B. Feb. 11, 1960 [Feb. 21, 1959], No. 4938/60. Class 106 (1). A punched record 1 (Fig. 1), e.g. a tag for attachment to merchandize in a shop consists of a plain piece of metal foil or a layer of paper coated on one side with metal foil, the holes 4 being punched through both layers. The record is read in apparatus as shown in Fig. 3, consisting of an insulated bed 11 having sensing pins 7 at each perforation position of the three fields 4a, 4b, 4c of the card and locating pins 6 for engagement in holes 5 in the record. A press plate 10 is brought down on to the record to drive the sensing pins well into the foil surface of the record as shown in Fig. 1, so that any oxide coating is ruptured and firm contact is assured. Potential is transmitted to the foil surface by contact with two or more bars 8. Small holes may be provided in the press plate opposite each pin 7 and larger holes opposite the locating pins 6. In the form shown in Fig. 7, the press plate 10 is normally held in the raised position by its attachment to a spring-loaded pin 17 and it is forced downwardly for the reading operation by movement to the right of a slide 23. Balls associated with this slide roll in tapered slots and by a wedge action bear against the top plate 38 and the press plate 10 to increase the distance between them. The slide is operated by a solenoid 22 and retained in the operative position by a catch bar 29. This is released by operation of solenoid 32. When the record is inserted, control pins such as 15 are raised and contacts 20 open. When it reaches the correct position it falls over the locating pins and pins 15 are lowered to close their contacts 20 and energize solenoid 22. This moves the slide 23 to the right for the sensing operation, the locating pins being raised by cam action during this movement. Solenoid 22 is de-energized, the slide then being held by the catch bar 29 which in its upward movement closes contacts 12 to apply the sensing potential, to transfer the data to associated apparatus 9, Fig. 3. This energizes the solenoid 32 to end the sensing operation. The record is then released and may be removed.

Title: Process for the production of coloured artificial fibres and the like from normally solid ethylene polymers
IPC: C08K5/00
Filed: 1946-02-20
Abstract: Coloured ethylene polymer fibres which are level in colour and which are fast to washing and sunlight are obtained by dispersing a dye or pigment in a normally solid ethylene polymer and extruding the mixture into fibres.  The mixture may be extruded in the form of a melt or in solution in a solvent such as xylene, benzene, toluene, ethylene dichloride or trichloroethylene. Numerous suitable dyes or pigments are specified, and the average particle diameter of the pigment should preferably be less than two microns.  A solution of the dye may be added to a solution of the polymer and the mixture extruded into an evaporative medium flowing co-currently or countercurrently with the direction of extrusion and at a temperature above the melting point of the polymer.  Alternatively, the dye or pigment may be dispersed in a solution of the polymer and the blend incorporated with the main batch of polymer which is then extruded in the absence of oxygen. The ethylene polymers are obtained by polymerizing ethylene alone or with an ethylenically unsaturated compound as described in Specifications 471,590 and 497,643. Examples of the ethylenically unsaturated compounds which are employed in minor proportion are mono-olefines such as propylene, halogenated ethylenes such as 1 : 2-dichloroethylene, vinyl chloride and vinylidene fluoride, vinyl ethers and ketones such as methyl vinyl ether, methyl and ethyl vinyl ketones, vinyl esters such as vinyl chloroacetate, propionate and acetate, N-vinyl phthalimide, vinyl thiolacetate, styrene, acrylic and methacrylic acids, esters, amides and imides, esters of maleic and fumaric acids and esters of itaconic acid. To the blend of polymer and dye or pigment, protective colloids such as polyvinyl alcohol, casein and starch, and wetting agents such as longchain alcohol sulphates and sulphonates may be added. Examples are given of the preparation of the spinning composition wherein (1) copper monochlorophthalocyanine powder is incorporated in a xylene solution of polyethylene, and (2) a xylene solution of an oil-soluble dye made by coupling aminoazobenzene to beta-naphthol is added to a xylene solution of polyethylene. Specifications 472,051 and 565,282 also are referred to.
