Abstract: 638,989. Internal grinding and polishing. SCHEID, O. Feb. 15, 1947, No. 4465. Convention date, Feb. 15, 1946. [Class 60]  A cylinder grinding device comprising a plurality of sectorshaped bodies adjustable in common and to an equal degree in a radial direction, wherein the grinding bodies when retracted to a minimum radius abut circumferentially and provide a substantially complete circle, is characterized by the feature that the length of the individual grinding surfaces in the circumferential direction does not exceed <SP>1</SP>/ 24 th of the circumference of the smallest cylinder that can be ground with the device. One construction comprises twenty-four sector-shaped grinding bodies 1, Fig. 1, with-grinding surfaces 2 which may be composed of diamond dust suitably bonded. Each body has a shank 3 moving in a radial groove in the tool, the shank being internally threaded for engagement by an adjusting screw 6 provided with a gear-wheel; the gears all mesh with a common crown-wheel, ensuring simultaneous and equal radial adjustment, adjustment of the crown-wheel being effected through gearing 13, 14, 15, 16, by a plate 17 with a Vernier scale 17<SP>1</SP> ; the parts are locked in adjusted position by a nut 19. Alternatively, adjustment may be made by turning a plate having a multiple Archimedian spiral engaged by projections in the shanks. The grinding surfaces 2 have a radius of curvature which is the average of the minimum and maximum radii of curvature obtainable by radial adjustment of the bodies. The surfaces may also be curved in an axial direction.

Title: Improved method and apparatus for the classification of materials
IPC: B07B7/08
Filed: 1937-02-15
Abstract: 490,393. Centrifugal separators. CAREY, W. F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 15, 1937, No. 4549. [Class 23] Powdered materials are divided into coarse and fine fractions by the simultaneous action of centrifugal force and an opposing stream of fluid; the radial velocity of the fluid varies so that the pressure of the fluid balances the centrifugal force acting upon any particle of the size corresponding to the desired line of separation. A rotor 1 on the shaft 3 rotates in the casing 2 and has a number of radial plates 5 surmounted by a cowl 6. The materials to be classified are supplied through the tubes 8 and are constrained by the cylinder 7 to pass through an annular slit 9 in the cowl 6 to the inside of the rotor where they are subject to centrifugal action. A suction fan at the orifice 10 draws air or other gas through the vents 11 in the casing, and through the rotor from its circumference. The cowl is designed so that the inward radial velocity of the gas diminishes and the force it exerts upon a particle of the required size just balances the centrifugal force. Particles larger than this size move outwards and drop into the casing while the smaller particles are drawn through the orifice 10. The radial plates 5 have slots 14 to prevent material from accumulating between the plates, and the base of the rotor has circular ridges 16. In a modification, the rotor works on a horizontal axis and has rings of plates which forms zigzag channels for the passage of the materials and the gas. Specification 220,671, [Class 23], is referred to.
