Title: Improvements in apparatus including a rotary part intended to undergo a slowing downor braking action, and in particular improvements in textile double twist throwing spindles
IPC: D01H1/10
Filed: 1952-09-06
Abstract: 733,467. Double twist spindles. SOC. D'ETUDES ET DE RECHERCHES DE MATERIEL TEXTILES. Aug. 24, 1953 [Sept. 6, 1952], No. 23305/53. Class 120(2). [Also in Group XXXIV] Apparatus including a rotary member intended to be subjected to a slowing down or braking torque has the rotary member supported by a fixed hub with a rolling bearing interposed between said hub and said member and resilient braking elements interposed between at least some of the rolling means and the races of said bearing, the braking elements being subjected to the action of adjustable thrust means acting in the axial direction and wedging the elements to a greater or lesser degree between said races so as to vary the braking effect of these elements. As shown the invention is applied to an unwinding disc 6 of a textile double twist spindle. This disc 6 is mounted on a fixed hub 4 by means of a ball bearing between at least some of the balls 11 of which are interposed resilient braking elements 14. These elements 14 are compressed by adjustable thrust means comprising a nut 16 screwed on to the hub 4 and acting upon an abutment 15 through rubber rings 17 and a thrust ball bearing 18. The elements 14 are preferably of a porous material such as sponge rubber so that they can be impregnated with a lubricant, for example, silicone.

Title: Manufacture and application of new polymerisation products
IPC: C08F236/04
Filed: 1936-08-25
Abstract: Synthetic rubber-like materials adapted to yield vulcanizates having a high resistance to abrasion are obtained by polymerizing in aqueous emulsion butadiene together with an amount of methyl methacrylate not less than 10, and not more than 100 per cent of the weight of butadiene.  Polymerization may be effected by passing the requisite quantity of butadiene into a mixture of water or ice, methyl methacrylate and other ingredients.  Small proportions of electrolytes, e.g. acetic acid alone or admixed with sodium acetate, and catalysts, e.g. hydrogen peroxide, may be added.  Latex-like products are obtained which are coagulated by adding ethyl alcohol &c. and the coagulum is washed and dried on heated rollers.  In examples 1, 3 and 4, butadiene, methyl methacrylate, cetyltrimethylammonium bromide and acetic acid are mixed together and agitated in a closed vessel at 60 DEG  C. and the product is coagulated with ethyl alcohol.  In example 5, cetyl-p-dimethyl aminobenzoate methosulphate is employed in place of cetyltrimethylammonium bromide and coagulation is effected with sodium hydroxide.  Vulcanizates are obtained by heating to 141 DEG C. a mix of the product with carbon black, stearic acid, zinc oxide, mercaptobenzthiazole and sulphur; phenyl-a -naphthylamine may also be added.  Specifications 360,822, 387,381, 401,653, 405,699, and 427,810 are referred to.ALSO:Synthetic rubber-like materials adapted to yield vulcanizates having a high resistance to abrasion are obtained by polymerizing in aqueous emulsion butadiene together with an amount of methyl methacrylate not less than 10, and not more than 100 per cent of the weight of butadiene.

[Also in Division G3] A closure for ventilation shafts automatically closable upon sudden changes in the ambient atmosphere comprises a double acting piston 7 carrying the closure, the pressure applied to the upper side of the piston through a pipe 8 exceeding the pressure supplied through a pipe 9 which normally maintains the closure in its open position. This difference in pressure ensures rapid closing when pipe 9 is open to exhaust. Sensing means 27 may be responsive to pressure, temperature, radiation intensity, or may be a Geiger counter, and controls two electromagnetic valves 17, 19 controlling the flow in pipes 9, 8 respectively from reservoirs 18, 20 to the cylinder 6. Reservoir 18 is at a lower pressure than reservoir 20. The cylinder 6 is appreciably longer than the stroke of piston 7 necessary to close the closure. The closure may be arranged in a horizontal shaft (Fig. 2) and a fan (2, Fig. 1) may be provided. The closure (4, Fig. 1) seats on sealing means (3a, Fig. 1).

Title: Improved fumigant compositions
Filed: 1933-08-24
Abstract: An alkaline-earth cyanide, for example calcium, magnesium, or barium cyanide, is mixed with a water-soluble salt of a base the cyanide of which is less stable to water than the alkaline-earth cyanide, and/or a water-soluble salt having a high heat of hydration.  The rate of evolution of hydrogen cyanide by reaction with water or atmospheric moisture is accelerated.  Salts falling within both of these classes, e.g. aluminium or magnesium sulphate or chloride, are preferred. Calcium chloride and sodium sulphate are also suitable.  The salts may be mixed and water added, or the accelerating salt dissolved and the cyanide then added.  The mixture may be used for dusting plants, inert diluents being added if desired.  The salt of a base forming an unstable cyanide is preferably added in 50--100 per cent excess of the stoichiometric proportion.  When liquid water is used for the reaction the quantity should be such that only a small amount appears in the residue.  The invention is applicable to mixtures or "chemical combinations" containing alkaline-earth cyanides.ALSO:An alkaline-earth cyanide, for example calcium, magnesium, or barium cyanide, is mixed with a water-soluble salt of a base the cyanide of which is less stable to water than the alkaline-earth cyanide, and/or a water-soluble salt having a high heat of hydration.
