Title: Improvements relating to polyurethane-type coatings for electrical conductors
IPC: C08G18/66
Filed: 1963-07-31
Abstract: A polyurethane forming composition which is a bath liquid for coating electrical conductors comprises a solution of (i) an organic polyisocyanate containing an aromatic group, (ii) a diol containing an aromatic residue to which the hydroxyl groups are attached each by an aliphatic chain containing one or two carbon atoms and (iii) an organic compound of lead or tin.  Preferably the composition contains also a triol in which any carbon atom attached to a methylol group carries no hydrogen.  When the composition does not contain the triol it may contain glycerol or pentaerythritol. Components (i) specified are 3,31-dimethyldiphenylmethane 4,41-di-isocyanate; 3,31-bitolyene 4,41-di-isocyanate; diphenylmethane di-isocyanate and dianisidine 4,41-di-isocyanate. Components (ii) specified are 1,4-bis (hydroxymethyl) benzene; 2,4-bis (hydroxymethyl)-p-xylene; bis(2-hydroxyethyl) terephthalate; 2,2-bis (p-hydroxyphenylpropane) and the bis (2-hydroxyethyl) ether of hydroquinone.  Triols specified are trimethylolpropane and trimethylolethane.  Organic compounds of tin and lead specified are lead cresylate; lead naphthenate; lead phenate; lead m-cresolate; lead octoate; dibutyltin dilaurate and triphenyltin oxide.  The polyisocyanate may have been blocked by a phenol.  In the examples the solvent and blocking agent is a mixture of cresols (cresylic acid).  Mineral spirits may also be present to dissolve the organic salt.ALSO:Coated electrical conductors are made by forming on the surface of the conductor a coating of liquid (see Division C3) comprising a solution of (i) an organic polyisocyanate containing an aromatic group, (ii) a diol comprising an aromatic residue to which the hydroxyl groups are attached each by an aliphatic chain of 1 or 2 carbon atoms, and (iii) an organic compound of tin or lead, and heating the coating to cure it.  The liquid may also contain glycerol, pentaerythritol or a triol in which any carbon atom attached to a methylol group carries no hydrogen.  In the example wires are coated by dipping in a bath of the liquid and the coatings are then cured by passing the wires through a vertical furnace at 550-650 DEG F.

Title: Improvements in the production of artificial filaments
IPC: D01F2/30
Filed: 1939-12-05
Abstract: 537,042. Artificial filaments. DREYFUS, H. Dec. 5, 1939, No. 31518. [Class 2 (ii)] Artificial filaments are obtained by extruding a solution of cellulose acetate or other cellulose derivative downwardly into a . co-current of heated air or other evaporative medium so as to obtain filaments of a denier of at least 7 while maintaining conditions such that the expression 1/l(ds/10 + 0À75s) has a value greater than 50, where d is the amount by which the filament denier exceeds 7, s is the spinning speed in feet per minute and l is the length of travel of the filaments in the evaporative medium in feet. The length of travel is preferably more than 20 feet and the spinning speed may be of the order of 300 feet per minute. Filaments having initial deniers of 10, 15, 30, 50, or more may be produced. These filaments may be subjected to a stretching operation, if desired in presence of a softening agent, so as to obtain filaments of high tenacity and of a final denier of 1-5. The stretching may be effected in presence of wet steam, or hot water under pressure at above 100‹C., or in aqueous or other solutions of solvents such as acetone, or dioxane. Stretching may be followed by a shrinking treatment in presence of a softening agent such as a mixture of methylene chloride and a hydrocarbon. Instead of cellulose acetate filaments, other cellulose ester or ether filaments may be produced in a similar manner. The dry spinning cell is of such length as to permit the necessary length of travel of the filaments. The evaporative medium may be heated before and during its passage through the cell e.g. by means of banks of heating pipes. The air may be brought to a temperature just below or even above the boiling point, of the volatile solvent. Specification 389,823 is referred to.
