Abstract: 535,669. Organic acid phosphates ; resins ; printing; cellulose compositions. BECK, KOLLER & CO; (ENGLAND), Ltd. (Hodgins, T. S., and Hovey, A. G.). Oct. 18, 1939, No. 28139. [Classes 2 (ii), 2 (iii) and 15 (ii)] [Also in Group VIII] Acid alkylphosphates are used as catalysts to facilitate the hardening and polymerization of modified and unmodified urea-formaldehyde and urea-phenol-formaldehyde resins. Any organic compound having free alcoholic hydroxy groups may be used in the preparation of the acid phosphates. The following hydroxy compounds are mentioned : methyl, ethyl, propyl, butyl, amyl, octyl and lauryl alcohol, glycerol, ethyleneglycol, propylene glycol, butylene glycol, sorbitol, mannitol, trimethylene glycol, dextrose, starch, cellulose, castor oil and monoalkylethers of ethylene glycol. The catalysts enable films of solutions of the resins to be rapidly converted into clear, glossy, hard finishes which may be applied to paper, cloth, wood, leather, artificial leather and rubber. The catalysts may also be used with resins in moulding processes and the manufacture of laminated materials. Their use in the manufacture of grease-resistant paper and fabrics, for increasing the wet strength of paper, for increasing the water resistance of methyl cellulose and polyvinyl alcohols and as pigment carriers in printing is mentioned. Resins prepared from dimethylolurea and acetals of monohydric alcohols may be used. In examples : (1) an acid ester prepared from phosphorus pentoxide and the monobutylether of ethylene glycol is dissolved in a solvent such as ethanol, butanol, monobutylether of ethylene glycol, or an aliphatic or aromatic hydrocarbon, and used in the preparation of an air drying urea formaldehyde resin; (2) a resin finish is prepared from a solution of a urea formaldehyde butanol condensation product in a mixture of butanol and alcohol to which an acid ester prepared from castor oil and phosphorus pentoxide is added ; (3) an acid ester prepared by reacting with octyl alcohol a product obtained from the monobutylether of ethylene glycol and phosphorus pentoxide is added as a catalyst to a solution of a resin similar to that used in example 2 ; (4) an acid ester prepared from phosphorus pentoxide and 1 : 9-octadecanediol is used as a catalyst for a urea formaldehydebutanol resin and also for a resin prepared by ageing a mixture of diphenylolpropane, potassium hydroxide and aqueous formaldehyde, heating with urea and more formaldehyde and distilling off water after the addition of phosphoric acid ; (5) an acid ester prepared by wetting phosphorus pentoxide with butanol and reacting with ethylene glycol is used with a soluble, heat convertible resin obtained from urea, formaldehyde and ethylene glycol.

Title: Improvements in or relating to the construction of saloon bodies for cars
IPC: B62D25/06
Filed: 1939-10-20
Abstract: 534,496. Vehicle bodies. BISHOP, W. H. Oct. 20, 1939, No. 28294. [Class 108 (i)] [Also in Group XXII] The upper part of saloon car bodies of similar contours but different dimensions are made up of a small number of pressings adapted to be united along meeting edges which lie in the substantially flat part of the roof, the edges of the pressings being directly united for the largest size of body and material being trimmed off adjacent these edges before uniting the pressings to form smaller bodies. As shown in Fig. 2 the upper part of the body comprises two pressings 14, 15 comprising respectively the near end offside quarter and a part of the roof up to the longitudinal centre line 16, and a third pressing comprising the front or header panel 12 which meets the pressings 14, 15 along the line 17. For the largest body the pressings are welded together without modification along the lines 16, 17 which for smaller bodies an appropriate width of material is trimmed off the inner and front edges of the pressings 14, 15 as indicated by the lines 18 and 19 before welding the pressings together along their edges. Where the taper of the roof is insufficient to compensate for the reduction in width at the front, the header 12 is made in two parts and the inner edges are trimmed as required for the smaller sizes of body. When the roof has an opening adapted to be closed by a sliding panel, this opening is formed by the omission of the front inner corner of the pressings 14, 15 so that the size of this opening varies with that of the body. Instead of welding the edges of the pressings 14, 15 directly together, these may be connected by a rib 32 and to prevent entry of water while permitting entry of air, troughed flanges 35, 37 each with an upstanding lip 36 are secured to the underside of the pressings. A strip 39 is secured to the underside of the flanges 35, 37 and this and the rib 32 have openings 40, 34 for the entry of air.
