Abstract: 1,212,222. Centrifugal separators; removing floating impurities. NATIONAL RESEARCH DEVELOPMENT CORP. 30 Jan., 1969 [23 Jan, 1968], No. 3467/68. Headings B1D and B2P. A floating liquid or solid is separated from the supporting liquid on which it floats by causing the mixture of supporting liquid and floating liquid or solid to rotate so that the surface of the supporting liquids assumes an inclination towards the centre of rotation towards which the floating liquid or solid drains and from whence it is collected. The apparatus shown may be used for separating and collecting small samples of oil slicks floating on the sea. A tube 1 having a closed upper end provided with an air hole 5 has its lower open end surrounded by a tube 2 whose lower end is closed and whose upper end is open and situated a short distance below the surface of the liquid. The tubes are mounted within a casing 7 on a shaft 3 which carries a stirrer 6 and is driven by a motor 4. The casing is fitted with a buoyancy chamber 8 and weighted baffles 9. One or more deflectors (10), Fig. 2 (not shown) may be provided inside the casing to deflect the rotating liquid towards the centre of the casing. In a modification, Fig. 3 (not shown), the baffles 9 are dispensed with and the upper part of the casing adjacent the surface of the liquid is divided into rotor segments which react with the rotating liquid to produce some counter-rotation of the casing to assist in gathering oil into the casing. In operation, as the stirrer is rotated a vortex is formed within the casing. Oil on the surface of the liquid is carried inwards and downwards into the tube 2 and then upwards into the tube 1 where it is trapped. The oil may be removed continuously from within the tube 1 by means of an archimedean screw pump arranged along the axis of rotation. A number of stirrers may be mounted on the shaft 3.

Abstract: 964,797. Dry shavers. WAHL CLIPPER CORPORATION. Jan. 31, 1961 [Feb. 15, 1960], No. 3591/61. Heading B4B. An inner blade 24 for an electric dry shaver comprises a thin, prehardened, metal sheet having a perforated cutting region in which the metal between the perforations constitutes cutting teeth 30, the metal sheet being bent so that at least a portion of the sheet has a continuous and uniform curvature in cross-section, the teeth following the arcuate periphery of the bent metal sheet and having upturned cutting edges 32 which are defined by the acute-angled intersection between the outer surface 34 of the blade and the surface 40 of the blade metal facing the perforation. The perforations consist of parallel slots 26 which may be formed by an acid etching process to form straight-sided teeth 30 perpendicular to the direction of movement of the blade. Bending of the sheet, to form the cylindrical inner blade, by virtue of the stress in the prehardened metal, causes the edge at the acute-angled intersection to be raised above the outer surface of the cutting region by at least 0.000005 inch, as shown in Fig. 4, so that only the tips of the teeth bear on the outer cutter and friction is reduced.

Filed: 1933-02-07
Abstract: 416,411. Grinding &c. razor blades. BOOTH, J., 927A, Abbeydale Road, Sheffield. Feb. 7, 1933, No. 3682. [Class 60.] In an apparatus for grinding, lapping, polishing, or honing the edges of safety razor blades, or of strip steel from which the blades are made, the blanks or strips r, Fig. 3, are carried past the abrading appliances on the peripheries of two rotating feed wheels c, cc provided with locating-pins f of involute form, the blades or strips being held to the peripheries by means of pierced flexible bands or strips g, and being automatically transferred from the first to the second feed wheel. In the machine shown in Fig. 1, the two feed-wheels c, cc are arranged vertically one above the other, and are driven by worm and wheel gearing at equal but opposite speeds. The clamping bands g, gg associated with the two wheels are carried by pairs of pulleys h, hh so disposed that they contact with the peripheries of the feed-wheels over the arcs through which the blades move when being operated on by the grinding &c. wheels j, jj. After being carried by the upper feed-wheel past the upper wheels j, jj, by which the edges on one face of the blade are simultaneously treated, the blade is released by the flexible band g, but is still held on the wheel by a guard (not shown) extending round the periphery of the wheel and forming a channel for the coolant water. At the lower part of the wheel the blade is transferred by a stripper device (not shown) to the lower feed wheel, by which it is carried in a similar way past the lower grinding wheels, which treat the edges on the other face. Coolant water is pumped from a tank at the base of the machine and delivered to the upper grinding wheels, a system of water-guards (not shown) surrounding both the grinding and feed wheels, of which the latter are provided with channels w, Fig. 3, coacting with inturned edges on the guards. The axes of the grinding-wheels j, jj, which are arranged one on either side of the feed-wheels, are substantially in the planes of the feed wheels, the operating surfaces of the grinding wheels being approximately hyperboloidal. The bearings for the feed-wheel spindles are carried on slides enabling the wheels to be adjusted towards and from the blades, and the slides may be adjustable both horizontally and vertically. The grinding-wheels are trued by diamonds g carried by the feed-wheels in the same circumferential lines as the edges being ground on the blades. Interlocking switches ensure that the motors driving the grinding-wheels are running before the motor driving the feed wheels operates.

Abstract: 1,024,938. Two-part couplings. CHRYSLER CORPORATION. Jan. 29, 1964 [April 2,1963], No. 3797/64. Heading H2E. An electrical connector for connecting to a spark-plug includes a cable-gripping portion 14, barrel-shaped portion 12 formed by curling over arms 22 and 24, carrying means limiting the movement of sections 22 and 24 relative to each other. The connector is formed from a flat metal blank and the arms 22 and 24 have four notches 26 cut out of them to leave projecting lugs 28, 30, 32 and 34. When the arms are curled, the lugs are bent over so that lugs 32 and 34 slidably engage in notches 26 on arm 22 and lugs 28 and 30 in notches 26 on arm 24. This allows limited, relative, resilient movement of the arms 22 and 24 but prevents them being permanently deformed. The barrel member may be reinforced by means of a spring, Fig. 8 (not shown), which urges the arms into a closed position. The spring also serves to retain the socket in position on an inserted spark-plug by means of a lug which projects through a hole to engage a shaped portion of the spark-plug. In a further embodiment, Figs. 9 to 12 (not shown), instead of a lug projecting through hole 46, the blank is formed with detents which themselves engage an inserted spark-plug:
