Title: Improvements in water-dispersable adhesives from condensation products of formaldehyde and urea
IPC: C08G12/12
Filed: 1952-10-16
Abstract: A condensation product of urea with formaldehyde is subjected, during or after its drying by spraying, to a treatment between 100 DEG  and 200 DEG  C. until 20-50 per cent of it is soluble in cold water and the remainder only dispersible with swelling, and the treated product is dispersed in water to form an adhesive.  A water-soluble aminoplast, e.g. a condensate of formaldehyde with urea, melamine, urethanes, acetylene diurea or dicyandiamide may also be included in the dispersion.  The condensation is preferably performed at a pH between 2.5 and 5 with a molar ratio of urea to formaldehyde between 1.75 and 2.5.  Water-soluble cellulose ethers may be added to the condensates to improve their dispersibility and stabilize the dispersions and small amounts of swellable cellulose or starch derivatives may be included.  An addition of 10-20 per cent urea may also be made to improve the brushing properties and bind any free formaldehyde.  In the examples: (1) 1 mol urea is condensed with 2.2 mols. 30 per cent formaldehyde at a pH of 4-4.5 until resin separates on cooling. The solution is sprayed in hot air (inlet temperature 140-150 DEG  C.; outlet temperature 100 DEG  C.; residence time 1-2 seconds) and the powder heated for 5 hours at 120 DEG  C.  The product is mixed with a water-soluble urea-formaldehyde condensate, wood ether carboxylic acid and water to yield a spreadable adhesive. Example (2) is similar, using a water-soluble melamineformaldehyde condensate.  In example (3) the condensate is heated during spray drying (inlet temperature 160-165 DEG  C.; outlet temperature 110-120 DEG  C.) and is dispersed in water without other addition to form the adhesive.

Abstract: 303,434. Hotpoint Electric Appliance Co., Ltd., Clarke, E. R., and Sims, W. J. Oct. 3, 1927. Coiling; formers.-In the production of helices of oval or flat sided cross section the rotating mandrel 1 has a twisted part 1<a> beneath which is a burner 7 so that when oval or flat sided coils are being wound the wire is given an extra bend while heated to allow for the natural untwisting of the coil thus ensuring that the individual twists do form a continuous flat side when released. The coil as it is formed is pushed off the mandrel by a spring pressed abutment 8 bearing against the mandrel and reciprocating as its flat sides turn round. The abutment 8, Fig. 4 works in slots in discs 12 which can be set so that the abutment works at the angle of the helix being wound. The spring 10 pressing the abutment 8 can be compressed to give greater abutment pressure. When starting a new coil the abutment can be held retracted by a lever 20 slipped into a groove 21 in its spindle. The tubular guide 5 to receive the finished spiral is rotated by gearing at same speed as the spiral to prevent deformation.

Abstract: 535,021. Photographic developing processes. ARNOLD, J. C. (Harris-Seybold-Potter Co.). Sept. 19, 1939, No. 26200. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 12, 1940.] [Class 98 (ii)] A photographic developer, which may be of the fine-grain type, has incorporated therein as an additional preservative a reaction product obtained by passing sulphur dioxide into anhydrous morpholine at a temperature below 120C. and above the solidifying temperature of the morpholine until each molecule of morpho-' line has absorbed one-half molecule of sulphur dioxide, or one molecule of sulphur dioxide. In the latter case the temperature during the addition of the second half molecule of sulphur dioxide is maintained below 60 C. Sufficient water is added at the end of the reaction to effect crystallization. Re-crystallization from an anhydrous alcohol, such as isopropyl alcohol may be effected. Examples are given of the addition of this product to metol-hydroquinone, amidol, and pyrogallol developing compositions containing the usual ingredients and to a p-aminophenol-metol developing composition containing also sodium sulphite, salicylic acid, borax, and glucose. The developer may also contain hydroxy-aliphatic amine salts, such as salts of mono-, di-, and tri-ethanolamine, hydroxyethyl ethylene diamine, and diaminoisopropanol. The salts may be phosphates, hydrochlorides, hydrobromides, borates, or sulphites. The incorporation of the morpholine compound in a p-phenylenediamine-glycin developer renders possible the use of increased amounts of ethanolamine salts and reduced amounts of glycin. An example of a suitable developer of this type is given.
