Title: Improvements in apparatus for hauling vehicles
Inventor: HOWARD ALLAN MAURICE
IPC: B61J3/00
Filed: 1955-02-21
Abstract: 815,432. Hauling railway wagons. NORTONS-TIVIDALE Ltd. Feb. 21, 1956 [Feb. 21, 1955], No. 5130/55. Addition to 724,152. Class 104 (2). A bogie is mounted on a narrow track 14 between rails 16 and is drawn in one direction by a rope 44 connected to a cross-head 38 linked to outwardly moving wheel engaging rollers 18 and is drawn in the other direction by the other end 68 of the same rope connected to a cross-head 66 linked to upwardly moving axle engaging rollers 48. Both cross-heads run in a central channelled track 6 with an end stop 42. The rope is wound on a drum 78, Fig. 9, and is driven in either direction by a motor 112 or 114, on a control device 76. The motors drive a nut 130 on a shaft, which operates limit switches 132, 134 to limit the travel of the bogi. To vary the tension in the rope it is passed round a pulley 82 on a frame 86 slidable by a motor 96, operating a threaded rod 90, into one of three positions. In two positions the rope is additionally tensioned by a weight engaged by a plate on a loop of the rope. With the pulley 82 in the intermediate position the rope 44 slides the cross-head against the action of a spring 46 and through links 34 moves brackets 26 supporting rollers 18 outwardly to engage the wagon wheels 20. A roller 24 mounted adjacent and offset downwardly to each roller 18 is moved into contact with the rails 16. With the pulley 82 moved to tension additionally the rope 68, the cross-head 66 is moved against the action of a stronger spring 70 and through levers 64 raises lever arms 54, 56 moving rollers 48 upwardly into engagement with the wagon axle. The rollers 48 have a spring buffer 77. In operation with the pulley 82 in the intermediate position and the roller outwards the bogie is moved by the motor 114 to a position where the rollers 18 contact the wheels 20. A fluid coupling 126 prevents the bogie propelling the wagon. The pulley 82 is then moved so that the rollers 48 engage the axle 50. The motor 112 is operated to draw the bogie and wagon forwardly to their destination where the motor is stopped and the pulley 82 is moved so that both pairs of rollers 18 and 48 are disengaged and lie beneath the wagon. The bogie is then driven by the motor 114 with the rollers outwards to the next train of wagons. The motor 112 may be reversed and the wagons driven rearwardly. Specifications 688,467 and 688,468 are referred to.

Abstract: 514,989. Urea-formaldehyde condensation products. TATTERSALL, H. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 22, 1938, No. 5610. [Class 2 (iii)] A heat-hardenable synthetic resin is obtained by condensing, at a temperature above the boiling-point of water, formaldehyde, or a polymer or derivative capable of generating formaldehyde under reaction conditions, with a ureide of a half ester of a dicarboxylic acid in which the half ester group is free from any substituent of acidic or basic nature or capable of reacting with formaldehyde. In place of such ureides, corresponding derivatives of thiourea, biuret, thiobiuret, guanidine, semicarbazide or thiosemicarbazide may be employed. Preferably urea, a dibasic acid and a considerable excess of a monohydric alcohol are heated together and the product, which contains the ureide and excess of alcohol, as solvent, is then reacted with formaldehyde. When using urea, thiourea, guanidine or semicarbazide as anticatalyst for condensation of formaldehyde therewith, e.g., sulphur, phenol, resorcinol, bromine or iodine is preferably employed. Specified dibasic acids pic adifare succinic, maleic or phthalic, and specified esterfying groups are methyl, ethyl, n-butyl, isobutyl, cetyl, oleyl, stearyl, allyl and bornyl. Glycol dihydrogen phthalate may be employed in place of phthalic acid. By controlling time and temperature, e.g., 110-140‹ C., alpha-stage resins, soluble in benzene, alcohol, acetone and ethyl acetate and compatible with cellulose derivatives, may be obtained ; they may be used for the manufacture of lacquers, enamels, plastic and coating compositions which may be hardened by baking. #-stage resins, soluble in trichloroethane and hexachloroathane, and suitable for moulding purposes, may be obtained by further heating. In example (1) a mixture of fermentation amyl alcohol, phthalic anhydride, urea and sulphur is heated to 120-130‹ C. to form the ureide, cooled to 100-110‹ C., paraformaldehyde is added and the mass stirred and the temperature cautiously raised to 130-140‹ C., part of the amyl alcohol being allowed to distil over ; excess of amyl alcohol. is then removed by reduction of pressure to yield a syrupy, alpha-stage product soluble in alcohol, benzene, toluene, acetone and ethyl acetate and compatible with nitrocellulose. Further examples describe (2), the production of a #-stage product, (5) and (6), the use of n-butyl and ethyl alcohols, (9), the'use of glycol dihydrogen phthalate, and (3), (4), (7) and (8), similar preparations from thiourea, biuret, guanidine carbonates and semicarbazide hydrochloride respectively.
