Title: Improvements relating to the production of bevels on glass plates
IPC: B24B9/10
Filed: 1957-12-16
Abstract: 851,141. Grinding or polishing. PILKINGTON BROS. Ltd., and BREWIN, J. D. Nov. 20, 1958 [Dec. 16, 1957], No. 39113/57. Class 60. A rotary abrading tool 6 for use in apparatus for grinding, smoothing or polishing a bevel 10, Fig. 4, along the margin of a plate of glass 3 comprises a ring-like abrading surface 22 disposed at gradually varying radius from the centre of rotation 31 of the tool, the variation of radius being at least as great as half the width of the abrading surface. The variation of radius at a maximum is about equal to the width of the abrading surface. The ring-like abrading surface may be in the form of an ellipse, Fig. 8, mounted concentrically to the axis of rotation of the tool or a circular ring 22, Fig. 4, secured by bolts eccentrically to the axis of rotation of the tool or by bolts 23 concentrically to a disc 25 eccentrically mounted by bolts 26 to a shaft 14, the disc 25 being formed with a portion 32 serving as a counterweight. Weights 34 may be mounted on a stud 33 to effect accurate balance of the wheel. The variation in radius may be accomplished by mounting the rotating tool with an annular abrading surface on a rotating crank, the length of which is less than half the width of the abrading surface which may be of diamond dust. In apparatus for bevelling the edges of rectangular glass sheets 3, Fig. 1, the sheets are gripped between resilient pads 8, 9 of opposed conveyers 1, 2 vertically inclined to the desired angle of the bevel to be formed on the glass ; rollers 11 on rods 12 above the conveyers support the projecting portions of the sheets. During its passage between the conveyers, the margin of the sheet is operated on by grinding discs 5, the rotary tool 6 and polishing tools 7 being belt-driven from shafts 20 connected to individual motors separately adjustable. The grinding and polishing tools may be of conventional cup-shape or of the same form as the rotary tool; in the latter case the tool 6 may be of conventional cup-shape. More than one rotary tool may be incorporated in the apparatus. The tools may be operated in groups, the tools of each group having the same abrading power or consecutive tools may have progressively lower abrading power. Circular glass plates may be bevelled by being supported on a member constantly rotated so that the glass overlaps several tools.

Abstract: 1,045,929. Selective signalling. RADIO CORPORATION OF AMERICA. Sept. 25, 1964 [Oct. 16, 1963], No. 39211/64. Heading G4H. In a system for displaying a page of alphanumeric characters on a cathode-ray tube, of the type in which each character is displayed as a 7 x 5 mosaic of dots, the entire page is stored and each line of characters is repeatedly read-out to a coding device whereby during each line scan of the C.R.T. beam one seventh of each character is displayed so that after seven line scans the complete line of characters is built-up. This is repeated until the entire page is displayed. Since the C.R.T. raster is similar to an ordinary television-type raster (interlaced or not) the above signals can be mixed with the output of a television camera.

Title: Purification of mono-olefins by selective hydrogenation
IPC: C07C7/163
Filed: 1959-11-24
Abstract: In the purification of mono-olefines containing more unsaturated impurities by selective hydrogenation over a hydrogenation catalyst, the feed is diluted with olefine free from the impurities.  The diluent may be a recycle of purified olefine and the recycle is preferably greatest when the catalyst is highly active and is reduced, thereby reducing the space velocity, as the catalyst activity decreases.  Olefines containing up to 16 carbon atoms may be purified, especially ethylene.  The hydrogenation is effected at 70-1100 DEG F. and 40-500 p.s.i.g. at space velocities of 400-500 vol./vol./hr. over cobalt molybdate, palladium or platinum supported on alumina.  If desired the recycle stream may be controlled to give a constant flow through the reactor.
