Title: Improvements in or relating to methods of compounding rubber
Inventor: HICKSON ROY
IPC: C08L21/00
Filed: 1955-07-05
Abstract: The process for preparing a vulcanizable composition according to the parent Specification is modified in that the intimate admixture of a hardenable resin such as a urea-, phenol- or arylamine-aldehyde resin in a natural or synthetic rubber is prepared by mixing the resin in finely divided form with an aqueous dispersion of the rubber, and coagulating the mixture. Alternatively material capable of conversion into the resin is mixed with the aqueous dispersion of the rubber and the material subsequently converted into resin prior to the coagulation.  In an example, a mixture of aniline-formaldehyde resin and an aqueous natural rubber dispersion is prepared by adding aqueous formaldehyde to a mixture of latex and aniline hydrochloride and allowing to stand.  Coagulation is then effected by adding aqueous ammonia to raise the pH value of the mixture to about 9.6. The coagulated material is washed and dried and hexamethylene tetramine added thereto, and the resin in the material hardened by mechanical working on a mill for 20 minutes at 153 DEG  C.

Abstract: 824,434. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. June 21, 1957 [Aug. 6, 1956], No. 19675/57. Class 103 (1). A pneumatic servo-cylinder unit 12 has its piston 22 linked to a pair of spaced substantially parallel arms 16, which are pivoted, by a slotted connection, on a projection from a lever 14 disposed between the arms 16, the arms 16 and lever 14 being connected respectively by pushrods 60 and 64. between the operating pedal and the master cylinder for hydraulic brakes, neither of which are shown. When the pedal is pressed, rod 60 pivots lever 14 about pin 40, the top end of the lever operating a valve 30 to let atmospheric air in through port 36 and. the central passage 34 to the space behind the servopiston 22 and produce a brake application by movement of arm 16. During this initial movement of rod 60, and until the pin 72 on levers 16 has moved to the end of slot 70, no reaction is transmitted to the valve lever 14, the movement of the lever 16 causing the head of pin 92 to be biased against the projection on the valve lever 14, to provide a first stage of reaction to the valve lever 14. Therefore, when the pin 72 abuts the forward end surface of the hole 70, further movement of lever 16 produces a second stage of reaction back to the vehicle foot pedal.

Patent GB-1091063-A (GB)
Title: Production of cellulosic fabrics
IPC: D06M15/70
Filed: 1966-05-06
Abstract: The tensile strength of cellulosic fabrics rendered crease resistant by crosslinking is improved by a process comprising (1) stretching assemblages containing natural cellulosic fibres in a direction substantially parallel to the long axis of the fibres whereby an elongation of the cellulosic material is effected, (2) forming a fabric from the stretched assemblages of fibres and (3) crosslinking the fabric with a cellulose cross-linking agent.  The assemblages are yarns or bundles of fibres and include slivers, rovings, threads, yarns and ply-yarns and may comprise cotton or linen alone or in admixture with other fibres.  The assemblages may be stretched in one or more stages by up to 8% of their initial length, a stretching of up to 80% of their elongation at break being preferred.  Loose assemblages of staple fibres in the form of slivers or rovings may be stretched by application of the stress-producing forces across distances smaller than the staple length but the stress-producing force to assemblages of staple fibres in the form of yarns or ply-yarns may be across distances exceeding the length of the staples.  Stretching may be achieved by means of two delivery means operated at slightly different speeds, e.g. two pairs of rollers operated in series in which the second roller pair operates at a higher speed than the first roller pair, by means of two rollers which draw the assemblage past a friction-producing means, by means of two interlocking toothed rollers or one tooth roller pressed against a soft rubber roller or by means of devices in which the assemblages are pressed between two rubber draw tapes.  The fibres may be swollen by means of hot or cold water which may contain a wetting agent, amine solutions or steam during stretching and after stretching may be dried, in the case of single yarns or rovings converted into yarns or ply yarns, woven or knitted into fabrics, mercerized, bleached, dyed and/or printed and then treated with the cross-linking agent which may be a resin precondensate of formaldehyde with urea, thiourea, cyclic derivatives of urea in the form of heterocyclic 5-or 6-membered ring compounds, a carbamate, acetylene diurea or melamine, an acetal, an epoxide, a polyepoxide or a halohydrin.  The crosslinking agent may be applied to the fabric in the form of an aqueous solution which may also contain zinc chloride or nitrate by dipping, padding or spraying and the fabric then dried and cured.
