Abstract: 168,422. British Thomson - Houston Co., Ltd., (General Electric Co.). June 4, 1920. Driving-arrangements.-The gear for varying the speed of the electric driving-motor of ring- spinning machines in accordance with the requirements of the cop is located within the casing of the motor and driven from the machine by a shaft, and is returned to the starting position upon completion of the cop by means released by the ring rail. The brush-yoke 34 is adjustably connected by an arm 38 to a lever 41 adjustably mounted on a bell-crank lever 42, which is operated bv a cam 37 substantially the same shape as the building-motion cam. The cam 37 is mounted on a shaft which extends through the motor frame and is driven by sprocket-gearing from the building-motion cam-shaft. The lever 41 is connected by a link 46 with a ratchet disc 47, which is operated by a pawl 49 and an adjustable eccentric-rod 51 connected to the cam 37. The lever 41 is thereby moved relativelv to the lever 42 and operates the brush-yoke so that the amplitude of the variation in the speed of the motor is increased during the first stages of the winding of the cop, and the mean speed of the motor is increased until it is at its maximum, when the bob. bin is threequarters full and thereafter is diminished. The number of teeth taken by the pawl 49 is determined by adjusting the length of the rod 51, and the adjustment is such that the link 46 is over the centre of the disc 47 when the bobbin is threequarters full. The disc is rotated against the action of a spring 54, by which it is returned to its initial position when a retaining- pawl 55 and the pawl 49 are released by a rod 57 operated by the ring rail.

Patent GB-420163-A (GB)
Title: Improvements in the manufacture of cellular rubber and similar materials
IPC: C08L21/00
Filed: 1933-05-26
Abstract: In the production of a material having a cellular structure confining a gas and involving mixing with a concentrated aqueous rubber dispersion a volatile rubber solvent and vulcanizing ingredients, the mixture includes 25 to 200 per cent of a softening oil reckoned on the dry rubber content of the dispersion, with or without a setting agent additional to the volatile solvent.  The term "rubber" includes isoprene, butadiene and chloroprene polymers.  The softening oil may be paraffin oil of low flash point, in which case it serves also as the volatile solvent, rosin oil, in which case it serves also as the setting agent, or the substance known under the Registered Trade Mark "Vaseline" oil.  The volatile solvent, if petrol, serves also as the setting agent.  If the softening oil is not very volatile a large proportion of volatile solvent is required, and vice versa.  The setting agent may be ammonium carbonate, which may serve as an additional "blowing agent," or ammonium chloride, or a mixture of both.  In an example 130 parts of rubber latex of 70 per cent rubber content, 2 parts of sulphur, 2 of zinc oxide, 1 of accelerator, 2 of antioxidizing agent, 150 of paraffin oil and 5 of petrol (all parts by weight) are mixed and stirred to the consistency of cream.  Then a quantity of ammonium carbonate in aqueous solution, or rosin oil, is stirred into the mixture to cause it to set to a jelly-i.e. without separation of the serum from the rubber.  The material during setting may be rolled in the hands into compact balls, or the mass can be rolled into sheets or otherwise consolidated by mechanical or fluid pressure for instance during the initial stages of vulcanization, which is effected without or within moulds.  The material prior to setting may be poured into moulds so as only partially to fill them to permit expansion on formation of the cellular structure.  After vulcanization the mass even when cool consists of cellular rubber of approximately the bulk acquired on vulcanization.  If an absorbent sponge is required the mass may be mangled to rupture the cells after vulcanization.  Specification 381,975 is referred to.
