Title: Improvements in or relating to the manufacture of metal pellets
Inventor: AYERS PETER
IPC: B22F9/06
Filed: 1963-04-11
Abstract: Metal pellets, particularly of aluminium or aluminium base alloy, are manufactured by dropping droplets of the molten metal into a cooling bed or particulate material, such as alumina or an alumina-silica catalyst, fluidized by a gaseous medium. The solidified pellets removed from the bed may be passed over at least one vibrating screen to separate pellets of a selected size from the remainder. Preferably the pellet outlet of the bed opens to the top of that part of an inclined screen fitted with a mesh portion of size sufficiently small to prevent the passage therethrough of the pellets but large enough for the particulate material which may be conveyed back to the bed through a cyclone.

Abstract: 976,522. Coffee-making machines. J. M. BARRERA. April 16, 1963 [April 16, 1962], No. 14771/63. Heading A4D. In a pneumatically or hydraulically operated coffee-making machine in which the operating sequence is controlled by valve operating cams on a shaft 19, the drive from a continuously running electric motor is transmitted to shaft 19 by way of a clutch mechanism controlled by the shaft. The motor driven shaft 1 drives a worm wheel 3 fixed on a splined sleeve freely mounted on shaft 4. Collar 8 is slidable on the sleeve. On pressing the start button of the machine, shaft 5 is turned to move lever 6 into engagement with arm 7, where it is retained by the pressure of spring 13A, and through fork 9, teeth 8A are moved into engagement with teeth 8B on worm 10. The shaft 19 continues to rotate until hose 14 strikes roller 15 on arm 7 and relieves lever 6 of the pressure of spring 13A. A return spring rotates shaft 5 to disengage teeth 8A, 8B and break the drive. A lost-motion connection is provided between disc 13 and worm-wheel 11.

Title: Method and Apparatus for Surface-Finishing Workpieces
IPC: B24B31/00
Filed: 1967-03-31
Abstract: 1,180,589. Finishing. H. KOBAYASHI. 31 March, 1967 [18 June, 1966 (3)], No. 14931/67. Heading B3D. A method of surface finishing workpieces comprises: (i) moving a portion of loose abrasive material along a rectilinear path to form a stream, the portion having a substantially uniform density and a predetermined cross-sectional profile, and (ii) moving workpieces one after another, either immersed in the stream of abrasive material or along the surface of the stream of abrasive material, at a predetermined relative speed in a direction opposite to the direction of the stream so that the workpieces are in surface-finishing engagement with the abrasive material. One embodiment, Figs. 1 and 3, comprises an endless carrier 14 passing round two horizontal wheels 10, 12, the wheel 10 being driven. The carrier may be of stainless wire net of very small mesh and contains loose abrasive 22. Support rollers 16, 18, 20 maintain the carrier in a U-shape. A series of workpieces, in contact with the surface of the abrasive or submerged therein, are moved along one rectilinear path L oppositely to the movement of the carrier, while another series is moved along the other rectilinear path L<SP>1</SP>; alternatively, the workpieces are moved along path L and then along path L<SP>1</SP>. The abrasive may be a powder or granules and have a mean diameter of 0À01 mm. -50 mm. It may be used dry or wet, e.g. with water, a surface active agent, a glossing material &c. The paths L, L<SP>1</SP> may be 1 m.-10 m. The abrasive travels at 70-300 m./minute. The treatment time is 10 secs.-15 mins. Another embodiment, Fig. 4, comprises vertical wheels 40, 42 round which passes an endless carrier 44 of flexible material, e.g. corrugated flax-filled urethane rubber, the carrier containing abrasive 52. Rollers are so arranged that the carrier is an open-topped channel along the upper straight run in which finishing is performed, while it is closed round the wheels and along the lower straight run, to prevent escape of abrasive. Workpieces may be tilted at an angle to the direction of travel and/or rotated. A further embodiment, Figs. 9, 10, comprises two inclined carriers 114, 114a containing abrasive 124, 124a. Abrasive from the upper end of carrier 114 passes through shoot 122 to the lower end of carrier 114a and abrasive from the upper end of carrier 114a passes through shoot 122a to the lower end of carrier 114. Workpieces travel down the upper run of the carrier 114 and then down the upper run of the carrier 114a; alternatively, the carriers 114, 114a may be in separate working lines.
