Abstract: 1,033,104. Honing. Y. KONDO. March 21, 1963 [Oct. 9, 1962], No. 11249/63. Heading B3D. An automatic size control for a honing machine has a gauge ring rotatable by a honing tool when the workpiece is of predetermined size, a size-detecting plunger movable by the gauge ring to cause a change in pressure of fluid supplied at a constant pressure, means for sensing the pressure change and converting it into an electrical signal which effects cessation of honing. Cutting oil in a tank 4 is pumped by a pump 7, driven by a motor 6, through a non-return valve 9 to an accumulator 11. A pressure control valve 10 and pressure gauge 8 are provided. The cutting oil is the same as that used in the honing process. The cutting oil is supplied at constant pressure to a plunger 16 having a discharge port 17 and a smaller discharge port 18. The cutting oil is also supplied at constant pressure to a plunger 15. The plungers 15, 16 co-operate with a rotatably mounted gauge ring 14. When the workpiece bore is of the required size, the honing tool engages the gauge ring 14 sufficiently tightly to rotate the ring against the loading of the plunger 15. The plunger 16 is thus moved to close the discharge port 17 thereon. The resulting pressure rise is detected by a Bourdon tube 13 or bellows which operates a switch 12 to terminate honing. Cutting oil discharging through the ports 17, 18 keeps the gauze ring 14 clean.

Abstract: 513,742. Moulding synthetic resins. RENFREW, A., DAVISON, J. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 19, 1838, No. 11738. Drawings to Specification. [Class 87 (ii)] Polymerized ethylene is compression moulded at a temperature not less than the melting point of the polymer. The melting point is defined and determined by placing a disc of polymerized ethylene on a flat steel plate and subjecting it to a uniform load of 1 kg. from a steel cylinder placed thereon. The temperature is raised and the relative movement of the cylinder and plate is plotted against temperature. Near the melting-point the movement increases sharply to form a substantially vertically straight portion of the plotted curve and the melting point is defined as the intersection with the temperature ordinate of the extrapolation of that straight portion. The melting point is normally 100-120‹C. and the moulding temperature is preferably about 10‹ higher, for example, 125‹ or 130‹C. Pressure is maintained on cooling and may be increased gradually. In an example, a sample whose melting point was determined at 116‹C. was moulded at 130‹C. and a pressure of 200 lb. per sq. in., the pressure being finally raised to 1,100 1b. as the temperature dropped to 90‹C.

Filed: 1937-04-26
Abstract: 497,832. Explosives. TAYLOR, J., WILLIAMS, V. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 26, 1937, No. 11931. [Class 9 (ii)] A method of producing a low-density blasting- explosive, free from self-explosive sensitizers, consists in incorporating ammonium nitrate and cork meal, with or without additional ingredients other than self-explosive sensitizers, with sufficient water to form a paste and then drying and granulating to yield a product of sufficiently low bulk density to be sensitive to the direct impulse of a commercial detonator. The proportion of cork meal preferably lies between 10 and 15 parts per 100 parts of ammonium nitrate and the compositions produced in accordance with the invention should have a bulk density below about 0À65 gram per cc. Other low-density vegetable cellular carbonaceous ingredients, such as bagasse, megasse or peat may be included and, in addition, a small proportion of relatively dense carbonaceous materials in finely divided form such as starch, dextrine or flour, may be added for example, 4 to 5 parts of starch per 100 parts of ammonium nitrate may be used. Safety or flame-quenching ingredients, preferably of an insoluble nature, such as granular limestone or coarse iron filings, may be included, but these ingredients should not be so finely divided that they occupy the voids between the particles of the other ingredients of the paste. In carrying out the invention, the wet paste is suitably spread out and dried at a raised temperature and the dried cake so produced broken up by light mechanical treatment and sieved through a coarse sieve, e.g. one lying between 6 and 30 mesh, in order to remove unwanted oversize particles. If desired, further quantities of coarse cooling or flame-quenching ingredients may then be admixed. Part or all of the ingredients of the composition may, if desired, be subjected to a preliminary mixing before the incorporation with water. According to the Provisional Specification, compositions may be produced by dry admixture of ammonium nitrate in powdered form with the cork meal.
