IPC: C08G69/26
Filed: 1969-07-03
Abstract: The invention comprises a method for the partial separation of the stereoisomers of 4,41 - diaminodicyclohexylmethane. The method consists in forming a salt of the isomers with a dicarboxylic acid and subjecting the salt mixture to a water wash, whereby a solid residue having an increased proportion of the trans, trans isomer is obtained.

Title: Method of preventing rack plating in continuous plating cycle for nonconductive articles
IPC: C23C18/16
Filed: 1969-09-08
Abstract: In a process of plating plastics articles by first forming a Ni or Cu electro-less coating and then electro-plating Ni or Cr, in which the articles are carried by racks sheathed in plastics, the racks are immersed in an aqueous solution containing hexavalent chromium to prevent electro-less plating on the plastics sheaths. The electro-less plating may be conventional using activating and sensitizing palladium and stannous chloride solutions and copper sulphate, formaldehyde, triethomolamine or nickel chloride, aminocetic acid, sodium hydroxide, sodium hypophosphate solutions. Examples are described of plating nylon, polystyrene, polysulphone, A.B.S., and polypropylene articles on p.v.c. plastisol sheathed racks or A.B.S. articles on polypropylene sheaths. The plastics articles may be etched before plating in a 14% wt. chromic and 40% sulphuric acid solution.

IPC: C08F8/00
Filed: 1969-09-17
Abstract: A macromolecular compound has, for a randomly chosen sequence of 100 monomer units, the formula in which a, b, c and d are positive numbers such that o < b # 80, c > o, a + b + c = 100 and d #l, M is a hydrogen or an alkali metal atom, the indicated monomer units may be in any order and, when d is greater than 1, the chain of acrylonitrile units may be partially branched and/or cyclized. The compound is prepared by reacting polyvinyl alcohol in an aprotic solvent first with a metallating agent and then with 1,3-propane sultone and then cyanoethylating or grafting the sulphonated polymer with acrylonitrile, anionically in an aprotic medium, preferably the same medium as that used for metallation and sulphonation. The metal sulphonate groups in the resulting polymer may be converted into hydrogen sulphonate groups. Specified metallating agents are alkali metal hydrides, amides, radical ions and carbanions. In the examples, polyvinyl alcohol is reacted in dimethyl sulphoxide with (i) sodium hydride dissolved in dimethyl sulphoxide (ii) 1,3- propane sultone and (iii) acrylonitrile. The resulting polymer is acidified and added to a dimethylsulphoxide solution containing an acrylonitrile/vinyloxybenzene sulphonate/vinylidene chloride copolymer, from which films are cast and dyed.

Title: Picture display device and deflection coil both having self-aligning surfaces
IPC: H01J29/76
Filed: 1975-04-30
Abstract: In a picture display tubes having deflection angles of 110 DEG and more the conical central part near the transition to the neck has a substantially flat variation perpendicular to the tube axis. As a result of this an accurate positioning of the deflection device on the display tube is seriously hampered. This problem is solved by centering members which are present on the conical central part and which cooperate in a self-centering manner with centering members forming part of the supporting cage of the deflection device. The position of the deflection device in the axial direction is accurately fixed by abutment members forming part of the supporting cage in co-operation with abutment surfaces forming part of the envelope of the tube.

Title: D and l-cyanocyproheptadine compositions containing it and methods of using it
IPC: C07D211/70
Filed: 1975-07-03
Abstract: (-)-1-Methyl-4-(3-cyano-5H-dibenzo[a,d]cyclohepten-5-ylidene)piperi dine and (+)-1-methyl-4-(3-cyano-5H-dibenzo[a,d]cyclohepten-5-ylidene)piperidin e are prepared in virtually pure form. These compounds are obtained by preparing the diastereomeric salts of the corresponding (+/-)-racemate in suitable solvents using optically active acids. The (-)-form, which is virtually free of the (+)-form, is then removed by crystallisation. The salt obtained is then converted into the free base, and the (+)-form is isolated from the residue as the free base. The (+)-form of the base and also the corresponding acid addition salts can be used as peripheral and central anticholinergics. The (-)-form of the base including corresponding acid addition salts can be used as sedatives.

Patent ES-476775-A1 (ES)
Title: A method of handling glass sheets.
IPC: C03B23/035
Filed: 1979-01-11
Abstract: In a method of heating a glass sheet which is moved on a conveyor which contacts one face of the sheet, anticlastic bending of the sheet is caused, and the stable anticlastic shape of the sheet is determined such that the sheet is arched away from the conveyor transversely of the sheet with respect to the conveying direction and with the sheet having a reverse curvature along its longitudinal extent so that the leading and trailing edges of the sheet are bent away from the conveyor. This reduces the contact between the contacted surface of each glass sheet and keeps the leading edge of each sheet clear of the conveyor. Anticlastic bending of the sheet is caused by producing a temperature differential between the central area and at least a part of the periphery of the sheet, for example, by heating said part of the periphery.
