IPC: C08G73/08
Filed: 1949-11-08
Abstract: Viscosity stabilized poly-4-amino-1,2,4-triazoles, suitable for the production of filaments and films, are prepared by heating together under polymerizing conditions reagents which on hydrolysis yield a mixture of dicarboxylic acid and sufficient hydrazine to yield a polymer resistant to hydrolysis by hydrochloric acid and, when the intrinsic viscosity has reached at least 0.25, adding less than 14 molar per cent based on the dicarboxylic acid of a monocarboxylic acid or the hydrazide, ester or anhydride or the nitrile thereof and continuing the heating under polymerizing conditions.  Specified monocarboxylic acids are acetic, propionic, butyric, valeric, stearic, lactic and benzoic.  Specified dicarboxylic acids are sebacic, pimelic, suberic, azelaic, phenylene-1,4-diacetic, sulphone - g ,g 1 - dibutyric, sulphone - d ,d 1-divaleric and sulphone-3,31-di-oenanthic.  In examples a low polymer made by heating a mixture of sebacic acid and aqueous hydrazine is heated with (1), (2) and (3) acetic acid hydrazide and aqueous hydrazine, (4) acetic acid and aqueous hydrazine, (5) hydrazine and acetonitrile.

Title: A method for Regulating Development of Crimp in Conjugate Filaments
IPC: D01D5/30
Filed: 1968-06-17
Abstract: 1,189,553. Regulating development of crimp in conjugate filaments. KANEGAFUCHI BOSEKI K.K., and SNIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 17 June, 1968 [15 June, 1967], No. 28650/68. Heading B5B. The development of crimps in composite filaments having latent crimpability and obtained by simultaneously melt-spinning at least two different thermoplastic synthetic organic to form composite filaments of the sideby-side or of the eccentric sheath-core type and drawing the composite filaments thereby formed is regulated by subjecting the filaments to a preliminary heating step in a primary heating zone at a suitable temperature and under a restrained condition such that the filaments do not develop crimps. The latent crimpability of the filaments is thereby reduced. The filaments are then further heated in a secondary heating zone in a tensionless condition, whereby they develop crimps to the desired degree. The temperature in the primary heating zone is selected according to the desired number of crimps per 25 mm. length of each of the filaments after the treatment in the secondary heating zone. The primary and secondary zones may have the same heating systems and the temperature in the primary zone may be the same as or lower than that in the secondary zone. The primary zone may have a dry heating system and the secondary zone may have a wet heating system of hot water or steam and the temperature in the primary zone may be up to 90‹ C. higher than that in the secondary zone. Both zones may have hot water heating systems. The primary zone may be a metal tube heating system and the secondary zone may be a jet crimper. The heating medium in both the said systems may be steam. When both the zones have hot water heating systems, the temperature in the primary zone may be 20‹ to 100‹ C. and that in the secondary zone about 100‹ C. When the primary zone is a metal tube heating system or a heated roller system and the secondary zone a jet crimper system or a cylindrical means for developing crimps, the temperature in the primary zone may be 20‹ to 180‹ C. and in the secondary zone about 180‹ C. Alternatively, the temperature in the primary zone may be 130‹ to 190‹ C. and that in the secondary zone about 190‹ C. The components of the composite filaments may be a homopolyamide and a copolyamide, a polyester and a polyester-ether, a polyamide and a polyester or polyolefins having different shrinkabilities or different intrinsic viscosities. One component may be nylon-6 and the other a copolymer of #-caprolactam and hexamethylene diammonium isophthalate or hexamethylene diammonium terephthalate. One component may be polyethylene terephthalate and the other polyethylene paraoxybenzoate or a copolymer of polyethylene terephthalate with polyethylene isophthalate or with polyethylene paraoxybenzoate. One component may be nylon-6 and the other polyethylene terephthalate.

Title: The manufacture of new salts of polyhydroxycarboxylic acids derived from polyaldoses
IPC: C07C59/105
Filed: 1933-10-18
Abstract: Heavy metal salts of polyhydroxymono-carboxylic acids derived from polyaldoses are made by reacting the free acids or their calcium, strontium, barium, or lead salts, in the presence of water, with oxides, hydroxides, carbonates, or other suitable compounds of heavy metals of the seventh and eighth groups of the periodic system. Aqueous solutions of the acids may be treated with carbonates or hydroxides of Mn, Fe, Ni, or Co, at a temperature up to 100 DEG  C., the salts being precipitated by addition of water-soluble organic solvents such as methanol, ethanol, or acetone.  Alternatively, salts of lactobionic or maltobionic acid such as barium lactobionate may be treated with, for example, ferrous sulphate, the barium sulphate filtered off, and the solution evaporated to dryness, preferably in vacuo. Aqueous solutions of the salts are used therapeutically by injection.  Examples describe the preparation of manganous, ferrous, ferric, and nickel lactobionate.

[Also in Division F2] In the manufacture of a lock-nut having a body portion 20 and a smaller thin-walled internally threaded collar portion 19, Fig. 6 (not shown), a workpiece is hot-forged in a die, Fig. 4 (not shown), to form the two portions and simultaneously to partially pierce the workpiece leaving a wad 23 which is subsequently punched out, Fig. 6. The operations are performed in a continuous sequence in a multi-station machine wherein the starting workpiece cut from hot bar stock is first descaled by pressing between tools 11, Fig. 2 (not shown). After inserting into die 13 the workpiece is pressed by punch 12 which forms the body 20 to hexagonal external shape, forwardly extrudes the collar 19 and simultaneously its nose 18 partially pierces the workpiece. An ejector rod 16 indents the other end of the workpiece and subsequently ejects the latter. In die 25, Fig. 6, the wad 23 is punched out by punch 29 passing through a stripper aperture 31. Alternatively the end of the collar may abut the die face during the punching operation. The workpiece is subsequently tapped. In use, the thin-walled collar of the lock-nut is deformed by a punch into a V-shaped slot 33, Fig. 7 (not shown), of the threaded shaft 32.

In the construction shown the forked ends 31 of the arm 28 are clamped on a spindle 12a, Fig. 2, and an auxiliary tube 35 surrounds the divided sleeve 15. Welded to the tube 35 is an arm 36 to the end of which is pivoted an adjusting rod 37 fitted with nuts 38, whereby the initial stress in the rubber 13 can be varied without raising the vehicle from the ground. A single upper arm 27 has a tubular inner end 29 embracing the sleeve 15, while the inner sleeve or spindle 12 is provided with serrated ends 39 engaging correspondingly serrated trunnions 30, such arrangement permitting an adjustment of the spindle 12 in the factory. In addition, the spindle 12 is capable of axial adjustment by means of screws 40 and nuts 41, so that the caster angle of the wheels may be adjusted. In order to lessen the plunging of the vehicle body due to deceleration in braking, the axis of the spindles 12, 12a preferably converge rearwardly towards each other as shown in Fig. 6. Modifications are described in which only the upper arm 27 or the lower arm 28 is mounted at its inner in a rubber bushing capable of adjustment whilst the vehicle body remains supported. In all constructions a doubleacting hydraulic shock-absorber 44 may be located between the arms 27, 28 or between an arm and a bracket, surrounding the rubber bushing.
