IPC: B24B31/06
Filed: 1969-03-04
Abstract: 1,221,517. Abrading. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 4 March, 1969 [6 March, 1968], No. 11444/69. Heading B3D. A method of finishing parts 17a, 17b, 17c in a finishing medium 16 comprises subjecting the medium to resonating vibrations. The medium is supplied from a hopper 22 to a chamber 19 in the form of a conduit or trough of elastic material which transmits sonic energy from a sonic vibration generator 20 to the medium. The generator may be of the orbiting mass type which has a roller or rollers rotating about an axis parallel or perpendicular to that of the conduit and produces a gyrating elastic standing wave motion with the ends and centre of the conduit undergoing a gyratory motion. The conduit is carried at nodal points by vibrationisolating means consisting of elastomeric bands 28, 33 in bands 29, 34, band 29 being pivotally mounted on a strut 27 and band 34 being pivotally mounted on a fluid-operated jack 36, 37 for adjustment of the inclination of the conduit. A conveyer 46 is provided at the lower end of the conduit for the discharge of the finished parts and a bin 45 collects the finishing medium which may be re-circulated. The medium may be aluminium oxide and may be dry, moistened or in the form of a slurry.

Abstract: 987,392. Creels; making cables. C. OSTERMANN, and M. OSTERMANN, [trading as W. & M. OSTERMANN]. March 18, 1964 [Sept. 9, 1963], No. 11446/64. Addition to 952, 633. Headings D1J and D1T. A plurality of filamentary wound spools 8 are mounted on a common shaft 1 that is supported at one end only, the spools 8 having friction discs 9 between them and being so arranged that the runoff direction of rotation of adjacent spools 8-are opposite to each other. This arrangement is stated to give a tension in the filamentary threads that is substantially uniform for all the spools. Spring means 18 act on a braking disc 10 to squeeze the spools 8 and the friction discs 9 together and the compressive force exerted by the springs 18 can be adjusted by rotating the nut 14 on the fixed annular member 13, the nut 14 having a plurality of bores 12, any one of which is engageable by the pin 15 to hold the nut 14 in its selected position. The spools 8 can be removed by first unscrewing the nut 20. The parent Specification indicates that the apparatus is suitable for use in a cable-armouring machine.

Class 110 (1) A fan comprises two discs 10, 14 of porous paper-like material mounted on a common hub 1, the air centrifugally displaced by the rotation of the discs being constantly replaced by air drawn with a filtering action through the material of the discs. On rotation, the partial vacuum created between the discs draws them together at their peripheries so that they each assume a frustro-conical shape. The formation of eddies which would cause fluttering of the edges of ure discs is prevented by a stabilizer 12. The diameter of the stabilizer is preferably equal to that of the discs, but may be greater or smaller. The discs and stabilizer, together with spacers 11, 13 (which are preferably of cork) are clamped in place by means of a flange 9 screwed onto the hub shaft 7. The fan may be provided with a casing.
