Abstract: 1382963 Phenolic-resin binder OWENSCORNING FIBERGLAS CORP 28 June 1973 [5 July 1972] 30735/73 Heading C3R [Also in Division D1] A mat or board of glass, slag or argillaceous rock fibres and phenol-formaldehyde resole resin is produced by forming streams of molten material, attenuating the streams to produce fibres, cooling them to 350‹ F. or below, applying a binder, collecting the binder coated fibres upon a conveyer and curing the binder, wherein the binder is obtained by condensing 1À5 to 4 moles formaldehyde per mol phenol in the presence of barium hydroxide until the product is insoluble at pH 7À5 and forming an emulsion by adding an anionic or nonionic dispersing agent and sufficient acid to adjust the pH to 7-8 before condensation has proceeded sufficiently for that precipitation of the condensate occurs when the pH thereof is 9 and higher. The dispersing agent may be an amine derived from a coconut fatty acid polymethacrylate or other polycarboxylic acid, an organic phosphate ester, an oxyethylated straight chain phenol, a diethylene triamine salt, a polyoxyethylenealkyl arylether or polyoxyethylene sorbitan monolaurate.  In Example I, 27,215 lbs phenol, 57,325 lbs 50% formaldehyde and 728 gallons water were heated to 110‹ F. whilst 2520 lbs barium hydroxide was added over 2 hours. The mixture was cooked at 125‹ F. for 2 hours, 840 lbs. barium hydroxide being added, and then for 4¢ hours at 150‹ F. 1000 lbs melamine crystals were added and after 1 hour 8200 lbs urea was added at 110‹ F. The mixture was cooled, brought to pH 7À2-7À3 with dilute sulphuric acid and 560 1bs coconut fatty acid amine added. The emulsion of partly cured resin may be mixed with dicyandiamide, urea, thiourea or melamine before it is applied to the fibres.

IPC: D01C3/00
Filed: 1924-12-22
Abstract: 243,301. Bach, R. Nov. 20, 1924, [Convention date]. Felt.-A process for working up animal fibres such as hair into felts more particularly for the manufacture of hats consists in treating the fibres with aldehyde or ketone carrotting-agents alone or with mercury or other metallic salt carrotting-agents. The process may be applied to loose fibres, to half fulled felt, or to hairy skins. The carrotting-agents may be added to the fulling liquid. The carrotting-agents may be applied in solution or in the form of vapours, and the process may be carried out under pressure and at temperatures above 100‹ C. After the treatment with the carrotting-agents, the material may be subjected to the action of oxidizing-agents such as hydrogen peroxide, permanganates, per borates, nitric acid, &c. Suitable carrotting- agents are formaldehyde, acetaldehyde, benzaldehyde, or their compounds with bisulphites, acetone, aceto-acetic ester, acetophenone, or mixtures or compounds decomposing into aldehydes and ketones. In an example, the hair of hares, rabbits &c. is placed in formaldehyde solution slightly acidified with sulphuric or hydrochloric acid and at a temperature of 25-80‹ C.

Abstract: 647,635. Counting-apparatus. MINISTER OF SUPPLY. Dec. 2,1948, No. 31213. [Class 106 (i)] In a binary counting circuit, a double.wound relay 1 controls the passage of input impulses from line 3, a differentially-wound relay 5 controls the operation of relay 1 during part of the cycle of operation of the circuit, and rectifier means 14 between the windings of relay 5 ensures energization of one winding 4 if the other winding 13 is energized but not vice versa. As shown, contacts 2 of relay 1 direct the first impulse received to the winding 4 of relay 5 which closes its contacts 7 to energize winding 9 of relay 1. Contacts 2 then change over to direct the second impulse to the output line 6 and through windings 12, 13 of relays 1, 5 respectively. Since current is sent also through winding 4, relay 5 is cut off, thus opening contacts 7 so that, at the end of the second impulse, relay 1 is also cut off and the circuit returns to the initial condition. More than one circuit may be used to " count-down " received impulses in ratios other than one to two.
