Abstract: 357,383. Safety razors. SHERMAN, J. C., 116, Main Street, Gorham, Maine, U.S.A. Oct. 6, 1930, No. 29885. [Class 30.] In a safety razor of the clamped blade type, the guard is provided with means to pick up or release a loose blade independently of the usual clamping means which are also provided. The clamping plate is longer than the blade so that the latter need never be touched by hand. In the form shown in Figs. 1 and 4, the guard 11 is integral with the hollow handle 10 to which are pivoted catches 26 pressed outwards by springs 28. In Fig. 4, the holder is in position for picking up the top blade 19 of a stack, the catches 26 being squeezed together until their shouldered ends pass through and underlie the blade which is then retained on the guard. The pivoted catches may be replaced by spring arms. The clamping plate 18, which is clamped by an internal nut 23, is recessed and the clamping screw is grooved to accommodate the catches 26. In the modification shown in Fig. 5, the blade catches 36 are carried on the guard adjacent its positioning apertures. The guard is split transversely at 35 and its two parts are pressed apart by the split resilient handle. The catches 36 are accommodated by recesses and grooves 37 in the clamping plate and positioning pins. In a modification of this form the guard is separate from the handle and its two parts are biased outwards by a U-shaped spring having an aperture through which passes the solid handle. A blade stand from which fresh blades may be picked by the guard is shown in Fig. 6, comprising pins 41 grooved to accommodate the catches 36 of the razor shown in Fig. 5. This stand has also a clip 48 for retaining the clamping plate 18 during and after its unscrewing from the razor, and there is also a clip 47 for the handle. The blades are spaced by paper spacers 38 with staggered finger-pieces 39. The ends of the posts 41 are tapered and shouldered to facilitate mounting the blades thereon. A modified blade stand, shown in Fig. 4, comprises only the pins 33, 34 for locating the blades, and transverse spacers 31 between the blades are used.

Title: Tension Control for Stretching and Winding Drives
IPC: H02P29/00
Filed: 1967-06-29
Abstract: 1,192,605. Tension regulating apparatus. INDUSTRIE-WERKE KARLSRUHE A.G. 29 June, 1967 [29 July, 1966], No. 30110/67. Heading D1D. [Also in Division G3] In a system in which a length of material is continuously fed or wound by a rotary member driven by an electric motor, the motor speed is controlled electronically by signals depdent on material speed and tension, the latter being determined from the reaction of a synchronous motor driving a member engaging the material. In Fig. 3, a filament 23, e.g. synthetic resin from a spinning nozzle 30, passes round a rotary member 31 driven by a synchronous motor 8 supplied from a variable frequency motordriven alternator 5 so that, at the Start, the motor runs at the same speed as the filament. Under these conditions the tensions in the filament on each side of rotary member 31 are automatically maintained equal since any difference causes movement of the stator of motor 8, by reaction torque, so that a transducer 18 is operated to cause appropriate adjustment of the speed of a motor 33 driving a further rotary member 32 engaging the filament. The speed of motor 33 is also dependent on the speed of alternator 5 since transducer 18 derives its output by adjusting a rectified output of alternator 5. A further rotary member 10 engaging the filament is driven by another synchronous motor 8 from an alternator 34 driven by motor 33 so that it runs at a speed corresponding to that of motor 33. The tensions on each side of rotary member 10 are also maintained in a desired relationship, despite increasing diameter of a bobbin 22 being wound by a motor 21, by utilising the reaction torque of motor 8 to control the peed of motor 21 through a transducer 18 in a manner similar to that used for controlling the speed of motor 33. Variation of tension during winding may be obtained effected by altering weights 26-28 biassing this transducer 18 through a pulley 25 which is camshaped and interchangeable. After starting, the other transducer 18 is reconnected and biassed by altering its weights 26-28 so that motor 33 runs at a higher .speed than the first motor 8 to produce stretching of filament 23 prior to, winding. Switches (not shown), operated when transducers 18 are at their limits of operation, are associated with fault indicators.
