Abstract: 811,641. Electrodialysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 28, 1957 [March 6, 1956], No. 7038/56. Class 41. An electrodialysing apparatus comprising a plurality of alternate, non- rigid cation- and anionexchange membranes 3, 4 positioned between an anode compartment 1 and a cathode compartment 2 has plates 6 of inert, resilient material, e.g. polythene, separating and contacting adjacent membranes 3, 4, each plate 6 having a plurality of channels 10 connecting in series a plurality of holes 11 in the plate 6 to provide a plurality of dialysing and rinsing compartments extending through the apparatus, means being provided for delivering a liquid to be dialysed to the channels 10 and holes 11 in alternate plates 6 and a rinsing liquid to the channels 10 and holes 11 in the remaining plates 6. Each plate 6 has a hole 9 at each corner, diagonally opposite holes 9 being connected by grooves 12, 13 on a face of alternate plates 6x, and by grooves 14, 15 on a face of the remaining plates 6y, with slots 7, 8 in each plate 6 which communicate with the channels 10. The channels 10 are formed by grooves in each face of each plate 6, two parallel grooves 10 connecting each vertical row of holes 11 in one face, and one groove 10, as shown in Fig. 4, in the other face. The holes 9 form passages extending the length of the apparatus, liquid to be dialysed being confined to one pair of diagonally opposite passages 9 interconnected by the grooves 10 in the plates 6x, and rinsing liquid being confined to the remaining passages 9 interconnected by the grooves 10 in the plates 6y, the holes 11 in the plates 6x thus forming dialysis chambers, and the holes 11 in the plates 6y forming rinsing chambers. Electrodes 21, both e.g. of platinum foil, Fig. 1, are each separated from the end membrane 3 or 4 by plates 5, 22 with an intervening, diaphragm 23 of ion-exchange or other permeable material, e.g. regenerated cellulose. An electrode solution which does not give rise to chlorine at the anode, e.g. of sodium sulphate, is circulated by a pump down one face of each plate 5 and up the face of the adjacent plate 22, the plates 5, 22 having grooves 10 and holes 11 similar to the plates 6 and being interconnected by nipples 24. The dialysis and rinsing liquids are supplied to and taken from the apparatus by nipples 25 leading to corner holes 9 in the plates 5, and both liquids are recirculated by a pump at a rate 10 to 20 times that at which fresh liquid is supplied to, and treated liquid is taken from, the apparatus. The electrode solutions leaving each plate 22 are mixed together and scrubbed with air or nitrogen before recirculating.

Title: Improvements in the manufacture of artificial filaments, foils and the like containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1934-03-08
Abstract: Artificial filaments, yarns, films, and the like are produced by extruding a solution of an organic derivative of cellulose in a volatile solvent into a liquid coagulating medium which contains a softening agent for the cellulose derivative having a boiling point above 100 DEG  C. and which is maintained at a temperature approaching or above the boiling point of the volatile solvent. Suitable softening agents are those specified in Specification 340,325, e.g., tricresyl phosphate or diethyl phthalate, and glycol monoacetate, methyl glycol monoacetate, diacetone alcohol, ethyl lactate, and diacetin.  The filaments, films and the like may be stretched during or continuously with their coagulation. In an example, an acetone solution of cellulose acetate is spun into an aqueous 30 per cent solution of glycol monoacetate at 55 DEG  C.  The products may be subjected to any after treatment, e.g. to treatment to improve extensibility or to produce effects as described in Specifications 380,504, 380,505, and 389,823, or to saponification as in Specifications 316,521, 318,468, [both in Class 2 (ii)], 402,104, 402,105, and 402,106.  According to the Provisional Specification, the shaped spinning or film-forming solutions are coagulated in the presence of solvents for the cellulose derivatives, or the coagulated products are treated continuously with their production with baths containing solvents, the coagulating or after-treatment baths being maintained above normal room temperature.

Abstract: 794,460. Coating webs; coating paper. AMERICAN CAN CO. March 12, 1956, No. 7736/56. Classes 96 and 140. A glossy coating is continuously formed on a travelling web (e.g. of paper) by applying a hot melt composition containing at least 10 per cent by weight of microcrystalline wax to said web, pressing the resulting coated web surface into intimate contact with a smooth, glossysurfaced backing while said composition is in the hot state, setting said composition in contact with said backing and then effecting relative separation of the backing and the coated web. Microcrystalline wax, alone or in admixture with paraffin wax, may be used and ester gum, synthetic resins and metal compounds of high molecular weight fatty acids may be added. The backing may be a polished nickel or chromium roll provided with means for cooling its surface or it may be an endless belt with which the wax forms a weak bond, e.g. of cellulose acetate, polythene, ethyl cellulose, regenerated cellulose or glassine paper and these may be coated with a separating aid such as a siloxane polymer. As shown, paper 20 passes from roll 16, through tensioning rollers 17-19, into the nip of pressure rollers 11 and 12 and into contact with endless band 13 of one of the above materials and passing round rollers 11 and 14. In the nip of rollers 11 and 12 the paper receives a coating of hot wax from fountain 10 and is at the same time united to the endless band 13 to form a temporary laminate 22 which is cooled by, e.g., a stream of chilled air 21. The web is stripped from the band at 23 and rolled at 25. According to alternative embodiments the wax may be applied to the web by dipping beneath a roll partially immersed in a bath of wax or by contact with such a roll.

Abstract: 1367899 Soldering SCIENCE RESEARCH COUNCIL 26 Jan 1972 [24 March 1971] 7741/71 Heading B3R An apparatus for soldering or desoldering comprises a soldering iron with an elongate bit 20 having a recessed end 21, and means for supporting the iron for movement in a direction normal to the longitudinal axis of the bit so that the recessed end of the bit can move along a predetermined path, the recessed end of the bit being such that when it contains molten solder forming part of a puddle of solder lying on the path, the bit can entrain the puddle of solder for movement therewith along the path to effect soldering or desoldering of members lying on the path. The soldering iron 6 is supported in a block 4 for sliding movement on two parallel rods 8, 10 carried in blocks 12, 14. The block 4 supports a bearing 16 through which the rod 8 passes and carries a roller which rests on the rod 10. The bit is cylindrical and its free end has a skirt 21 defining the recess 22. The apparatus is mounted above a printed glass fibre epoxy resin circuit board 24 having a row of parallel copper conductors 25 on each of which conductors is mounted a beryllium copper wire 26. In operation the points to be soldered which are aligned with the line along which the iron is constrained to move by the rods 8, 10 are coated with flux and solder is applied to the bit. As the solder melts it gathers in a puddle on the board and the iron is displaced along the rods 8, 10 to drive the puddle along leaving some solder at each joint. Solder may be taken from the joints by passing the bit with a reduced puddle of solder over the joints. The block 4 may be driven by an electric motor.
