Title: Razor blades and other cutting tools
IPC: B26B21/58
Filed: 1945-06-01
Abstract: 597,177. Razors. MACK, E. L. June 1, 1945, No. 13833. Convention date, May 16, 1944. [Class 30] [Also in Groups XXIII and XXXVI] A razor blade made partly or wholly of aluminium or of an alloy of high aluminium content, has its cutting edge or edges of oxidised aluminium. An aluminium blade may be oxidised over its whole surface or only at its bevelled edges. In producing a blade with a double bevelled edge, a blank may be entirely coated with a varnish resist, the edge ground on both sides to produce the double bevel and to remove the resist therefrom, the exposed faces oxidised in an electrolytic bath (see Group XXXVI) and the edge finally sharpened. Alternatively, the oxidisation may be performed after only one of the bevels has been formed, the other bevel being afterwards formed so that only one face of the blade is oxidised. Or the double bevel may be first produced, the whole surface then covered by the resist, the resist on one bevel being then removed and the surface oxidised. Further, a single bevel may be first formed, the blank coated with resist, the second bevel then formed and its surface oxidised. The blade may be of steel with an edge portion of aluminium secured thereto. In the case of a blade having a single bevel 8, Fig. 3, at each edge, the blade may be provided with holes 11 to engage projections on the razor which are so positioned that the blade cannot be inserted in the razor in an upside down position.

Filed: 1946-05-10
Abstract: 629,254. Electric control systems. STANDARD TELEPHONES & CABLES, Ltd., and DUNN, R. H. May 10, 1946, No. 14197. [Class 40 (i)] [Also in Group XL (c)] A variable electric function is translated into a variable rate of impulsing by means of a condenser which is charged at a rate controlled by the function and a second charged condenser which is connected to the first condenser in opposition when the charge on the first condenser reaches a predetermined amount. A variable negative voltage V is applied via resistance RM to condenser C, a high gain amplifier AMP with 180 degree phase shift being connected in parallel with condenser C as described in Specification 629,244 to maintain the potential or the input plate of condenser C at a substantially constant value. The output plate of condenser C is connected, if desired via a valve circuit or cold cathode tube, to a relay IR. The potential of this plate rises as the time integral of the voltage V and when this potential is sufficient relay IR operates. Contacts ir1 connect condenser Q, which has been positively charged by source E, to the input point, so that the charge on condenser C is reduced, relay IR releases, and the operation recommences. A second contact ir2 transmits pulses to a line. Variation of voltage V controls the rate of impulsing.

Abstract: 931,990. Electric correspondence-control systems. NORMALAIR Ltd. March 31, 1960 [April 28, 1959], No. 14472/59. Class 40 (1). [Also in Group XXIX] The control mechanism of a fluid motor driven winch is responsive via feed-back mechanisms to the amount of winding drum rotation and the winch acceleration. A helicopter winch 9 and rope guide 22a, Fig. 1, are driven through gearing by a rotary motor 6 controlled by valve 8 actuated through floating lever 2 by an operator's lever 1 or via an electrical actuator 2 by a remote pilot's control. A signal indicative of the amount of rotation of the winding drum recentres the control valve via the gearing, screw 12 and nut 13 and floating lever 14 linked to lever 2. The difference in speed between a flywheel 15 and the speed of the winch taken off the gearing adjusts a centre bevel gear 16 against a spring 18 and dash-pot 19 to transmit a movement indicative of winch acceleration to the floating lever 14 for adjusting the valve 8 to keep the winch speed constant. In Fig. 3 an electric signal from a winch operator or a remote pilot energizes one arm of a Wheatstone bridge to shift a flapper controlling. pressure on the ends of a piston valve 27 which moves to control the winch motor 28 and cable guide 48. The winch and cable movement alters a bridge arm 37 via screw and nut 35 to recentre the valve 27. A hollow member 38 rotatable on drum driveshaft 36 against centring springs 40 detects acceleration of the winch and adjusts two bridge arms 41, 42 which in turn adjust valve 27. Manual actuation of the winch is provided for at 21, Fig. 1 and 45, Fig. 3. The winch operator may perform large lifts by remotely controlling the helicopter through an automatic pilot and fine lifts by controlling, the winch. Specification 928,802 is referred to.
