Abstract: 816,979. Making heat exchangers, roofing &c. panels. FROMSON, H. A. Nov. 11, 1957 [Nov. 13, 1956; Dec. 19, 1956], No. 35093/57. Class 83 (2). [Also in Group X] In a method of making articles such as heat exchangers, and roofing panels from a combination of sheet metal and metal tubing, in which the interior of a tube is treated in known manner to prevent bonding, the tube is applied to a sheet and the assembly rolled to flatten the tube and bond it to the sheet. One or more treated tubes 1 are applied to a sheet 2 and the assembly rolled lengthwise of the tubes to effect the required thickness reduction and elongation. The rolled assembly may be annealed to improve bonding by causing recrystallization across the bond interfaces. A tool is then inserted between the unbonded surfaces 3 and the tube sections expanded by mechanical, pneumatic, or hydraulic means, resulting in a product having passages with relatively thin upper walls 4. In a modification the treated tubes are bonded between two sheets to produce tube portions of equal wall thickness. In another modification, a single tube 15 is bonded to one edge of a sheet 16, Fig. 9, which edge is then severed as at 18-18 to form a roofing, or like sheet, with a split edge 19, 20, Fig. 10, which may be of higher tensile strength than the rest of the sheet. The portion 19 of the sheet may form a flap to cover the head of a nail 22, and may also enclose the end of a neighbouring sheet 27 as in Fig. 12.

Abstract: 300,040. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 28, 1927. Cyanhydrins;a-hydroxycarboxylic acids.-The manufacture of a-hydroxycarboxylic acids bv the acid saponification of the corresponding nitrile is performed with a sufficient amount of water in the presence of an inert organic solvent or organic solvent mixture which is capable of dissolving the reagents and the reaction products, except the resulting ammonium salt. Suitable organic solvents are dioxane, ethyl ether, tetrachlorethane, chloroform. The nitriles may be prepared (by reaction of hydrocyanic acid with the correspond - ing aldehyde or ketone) in the inert, solvent afterwards required in the saponification, the water necessary for the saponification being added before or after the nitrile synthesis. In one example, acetaldehyde is led into a cooled mixture of dioxane, caustic soda solution, water, and hydrocyanic acid; the nitrile of lactic acid is formed and, when the reaction is complete, hydrogen chloride is led in to saponify the nitrile. The deposited ammonium chloride is filtered off and the dioxane is removed from the filtrate by distillation. In other examples, conducted similarly, benzaldehyde and propionaldehyde are used instead of acetaldehyde and the products are mandelic acid and a-hydroxybutyric acid respectively.

Title: Reprocessing flexible cellular materials
IPC: C08J11/18
Filed: 1955-12-12
Abstract: A process of utilizing scrap material of the kind produced from liquid reaction mixtures containing active-hydrogen-containing polymeric materials, an organic polyisocyanate and water comprises dissolving the scrap material in at least an equal weight of a liquid or molten active-hydrogen-containing polymeric material at an elevated temperature and forming from the resulting solution further cellular material by reaction with water and an organic polyisocyanate.  The expression "active-hydrogen-containing polymeric materials" means polyesters, polyesteramides, polyalkylene ether glycols, and mixtures of two or more of these.  Suitable materials are those described in Specifications 694,982, 696,449, 696,450 and 731,071 and in U.S.A. Specification 2,692,873.  Suitable polyisocyanates are hexamethylene, m- or p-phenylene, 4,41 - diphenylene, 1,5 - naphthalene, 4,41 - diphenylmethane, tolylene, 4,41-phenylether, 3,31 - dimethyl - 4,41 - diphenyl and 3,31 - dimethoxy - 4,41 - diphenyl diisocyanates; 4,41,411 - triphenyl - methane and toluene 2,4,6 - triisocyanates, 4,41 - dimethyldiphenylmethane 2,21,5,51 - tetraisocyanates, and mixtures of polyisocyanates such as those described in U.S.A. Specification 2,683,730.  Solution of the scrap material is effected by heating the mixture at temperatures up to 250 DEG  C., if desired in vacuo.  In examples: (3) and (4) scrap foam material is dissolved by heating to 250 DEG  C. under vacuum in a mixture of diethylene glycol/adipic acid and ethylene glycol/propylene glycol/adipic acid hydroxypolyesters.  The solution was mixed with polyethylene glycol, a polyoxyethylated vegetable oil (surface-active agent), N-methyl-morpholine, water and a mixture of 2,4- and 2,6-tolylene diisocyanates and poured into a mould to give a foamed product.  In a similar example, a diethylene glycol/adipic acid is used alone instead of the mixture of polyesters.  The scrap foam material is that obtained by reacting a diethylene glycol/adipic acid hydroxypolyester with a polyethylene glycol, a polyoxyethylated vegetable oil, N-methyl-morpholine, water and mixed 2,4- and 2,6-tolylene diisocyanates.

A thermographic copy sheet capable of undergoing visible change on brief contact with a metal test bar heated to a temperature with the approximate range of 90 to 150C. comprises a thin flexible sheet including a heat-sensitive layer formed from (a) a normally solid condensation product of a heterocyclic hydrazone and/or the hydrochloride salt thereof and an amine-reactive organic compound, and (b) a normally solid oxidizing agent and including an azo coupler component; either as a portion of the component (a) or as a separate component, or as a reaction product of the reaction between component (a) and the oxidizing agent, said components (a) and (b) being maintained in physically distinct, chemically non-reactive relationship but becoming chemically inter-reactive on heating. Typical examples of the hydrazone condensation products which are described and claimed in Specification 974,345 are hydrazones of the formula or azines of the formulae wherein Z completes a substituted or unsubstituted carbocyclic ring; R is alkyl; Y is -S-, -Se-, -OR # R# H# H# @ R# aryl group; V is -CO-;-CS-;-SO2-; W is alkyl, aryl, alkoxy, alkoxyalkyl, aryloxyalkyl, amino, arylamino or, substituted aryl with or without an active coupling position on an aromatic ring, with the further provision that when W is arylamino V is -CS-. The hydrazones I either may be such as to require the use of a separate azo coupler component, e.g. -VW is acetyl or other simple organic acid radical, or may include an azo coupler component radical, e.g.-V-W may be 1-hydroxy-2- naphthoyl-, or an aryl thiosemicarbazone radical. With azines of formula II or III the coupler component may result from the reaction of the azine and the oxidizing agent. Separate couplers may be used in any case and, in addition to the usual azo couplers of which numeral examples are given, the hydrazone-coupler condensation-products I may be used. Inorganic oxidizing agents may be used but the preferred oxidizing agents are-organic compounds having a chlorine or, less preferably, a bromine atom attached to a nitrogen atom. Fusible mild reducing agents such as benzoin may be included in the material to lower the copying temperature and improve the stability of the copy sheet. The components of the heat-sensitive material may be-dispersed in solutions. of binders such as styrene-isobutylene copolymer in heptane or toluene, polyvinylpyrrolidone in water containing a non-ionic dispersing agent, ethyl cellulose in alcohol or the may be incorporated without a separate binder within a fibrous web e.g. by impregnation. A transparent paper support may be employed and to provide protection for the heatsensitive layer and an opaque white background to improve contrast a thin covering layer as of titanium dioxide in a polymeric binder may be provided. Inert pigments or fillers may be included in the heat-sensitive layer to enhance contrast.
