Title: Improvements in or relating to the treatment of rubber latex and like aqueous dispersions of rubber
IPC: C08C19/08
Filed: 1932-02-09
Abstract: Natural and artificial dispersions of rubber and the like are pre-plastified by treatment with ozone, applied by passing a stream of ozonized air or oxygen through the dispersion probably in the presence of an anti-coagulating agent such as ammonia. After treatment the latex is allowed to stand at room temperature for 3-60 hours.  If desired a small quantity of a reducing agent substantially inert towards rubber and substantially a non-coagulant such as a sulphite, bisulphite, hydrosulphite, sulphoxilate, or a mixture of hydrosulphite and sulphoxilate is added after the standing period to counteract any tendency to deterioration due to residual excess of ozone.  The preplastifying process eliminates either wholly or to a very large extent the usual mastication process and the addition of softening agents.  The ozonized gas stream serves as the agitating means as it passes through the latex and ensures uniform contact of the ozone with the latex.  In an example a current of air is blown through an ozonizer capable of ozonizing 250 litres of air with 50 milligrams of ozone per litre, the ozonized air is passed for 10 hours through 15 litres of latex maintained at 15-40 DEG  C., thus introducing 33 milligrams of ozone per litre.  The treated latex is allowed to stand for 24 hours, 150 grams of bisulphite solution are added and the mixture stood for 24 hours when it is ready for use by direct deposition.  Specifications 284,608, 292,964, 330,520, [all in Class 70, Indiarubber &c.], and 351,012 are referred to.

Abstract: 1,141,003. Brake linkage. J. SCHOFIELD, and M. WILDING. 28 April, 1967 [29 Jan., 1966], No. 4088/66. Heading F2E. A parking brake for a road trailer vehicle comprises a worm b which is rotatable manually and drives a worm wheel b<SP>1</SP> mounted on a shaft 6<SP>2</SP>, an output member, in the form of either a drum b<SP>3</SP> to which is anchored a cable c, as shown, or a lever, being formed integrally with a sleeve b<SP>5</SP> on the shaft b<SP>2</SP> and releasably coupled to the worm-wheel by interengaging dogs b<SP>6</SP>, b<SP>7</SP> having inclined abutment faces whereby quick-release of the brake may be effected by means which normally maintain the wormwheel and output member in juxtaposition, as shown, but which on rotation of the worm-wheel in the brake-releasing direction allow the wormwheel to move axially away from the output member to release the dogs. The means consists of a pair of blocks d<SP>1</SP> carried by a ratchet wheel D which is freely rotatable on the shaft b<SP>2</SP>, and a further pair of blocks d<SP>2</SP> which are normally located opposite the blocks d<SP>1</SP> to prevent axial movement of the ratchet wheel and hence also of the worm-wheel. The ratchet wheel is engaged by a pawl d on the worm-wheel, the arrangement being such that when the worm-wheel is rotated in the direction to apply the brake the pawl slips over the teeth of the ratchet wheel, and when the worm-wheel is rotated in the brake-releasing direction the pawl rotates the ratchet wheel to a position in which the blocks d<SP>1</SP> are clear of the blocks d<SP>2</SP> whereby the tension in the brake cable c causes the dogs b<SP>6</SP>, b<SP>7</SP> to ride over each other, overcoming a spring b<SP>8</SP>, to effect a quick-release of the brake. The spring b<SP>8</SP> restores the parts to their normal positions on the next application of the brake.

Abstract: 938,925. Plutonium and plutonium alloys; nuclear fuel. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 3, 1961 [April 8, 1960], No. 4142/61. Drawings to Specification. Class 39 (4). Plutonium or plutonium alloys are obtained and plutonium is simultaneously decontaminated by reacting under an inert gas blanket a salt phase ; containing plutonium trichloride with cerium or cerium-cobalt alloy. The salt phase may consist of a eutectic mixture of plutonium trichloride and sodium chloride and may also contain LaCl 3  and CeCl 3 ; it may result from a process in which partially spent plutonium fuel displaces zinc in a chloride melt. The salt may be melted under argon in a MgOTiO 2  crucible and the reducing metal added as lumps of cerium-cobalt alloy or by lowering a rod of cerium into the melt. Reduction takes place at a temperature in the range 550-775‹ C. under about atmospheric pressure. Reduction with cerium yields a Pu-Ce alloy and with Ce-Co, a Pu-Ce-Co alloy ; these alloys are useful as reactor fuels. Apparatus is described with reference to drawings for carrying out the process in a batchwise fashion, semi-continuously, or continuously. Specifications 846,433 and 874,854 are referred to.
