Title: An apparatus for examining the cutting edge of a metal tool
IPC: B26B21/54
Filed: 1957-01-29
Abstract: 857,857. Photo-electric determination of cutting ability. AMERICAN SAFETY RAZOR CORPORATION. Jan. 29, 1957 [Feb. 1, 1956], No. 3152/57. Class 40(3). [Also in Group XXIII] An apparatus for determining the cutting ability of an edged metal tool comprises a source from which light can be cast on to the edge of the tool at an angle of 30 degrees off the perpendicular with respect to the length of the edge of the tool and light responsive means positioned above the edge to detect light reflected from imperfect parts of the edge. Arranged perpendicular to the edge 30 of a razor blade is a lamp 58 with two other lamps 60, 62 at 30 degrees on either side. Light from all three lamps passes through slots 68 and is focused by a lens 74 on to the edge 30. Light reflected from irregularities in the edge of the blade is focused by a lens 78 on to a photo-multiplier tube 48 via a prism 88 and lens 84. Beam splitters 76 pass the reflected light via rotatable polarising discs 100, a lens 94 and prisms 98 on to a ceramic reference surface 96. A shutter 91 allows either the calibration beam or the test beam to fall on the photomultiplier. The apparatus is housed in a light proof box (Fig. 4, not shown) containing a visual inspection tube and eyepiece and an adjustable razor blade holder (Fig. 7, not shown). Pulses produced by interruptions of the beam by the rotating drum 80, Fig. 2 are converted by the photo-multiplier 48, Fig. 19 and passed through a switch 348 to an amplifier 352, the output from which is fed through a gain control 356 to four cascaded amplifying stages 358, 360, 362, 364, the first three of which are provided with filters 366. A feedback is included in the second cascade stage 360. A potentiometer 361 zeroizes a milliammeter 342. A voltage regulator 363 minimizes fluctuations. A switch arm 354 allows one, ten or 100 % of the signal to be passed.

Abstract: 1,024,182. Discharge lamps. GENERAL ELECTRIC CO. Ltd. Jan. 2, 1964 [Jan. 30, 1963], No. 3819/63. Heading H1D. In a high pressure discharge lamp containing mercury, a rare gas and an alkali metal halide, e.g. sodium iodide, at a total operating pressure of at least 500 mm. of Hg, each of the two main electrodes is unactivated and consists only of a coil of tungsten wire wound around a tungsten rod, there being at least one empty space between the coil and the rod so that increased heating of the adjacent part of the coil during starting is sufficient to maintain an arc. The empty space may be provided by forming a recess in the tungsten rod, or by using a double coil witha gap in the inner winding and possibly also a two-part tungsten rod 18, 19 as shown, which also prevents over-heating of the electrode-to-envelope seal 6, 7. During lamp operation, at least partial dissociation of the metal halide vapour occurs; and the envelope temperature near the electrodes is maintained sufficiently high, i.e. at least 800‹ C., to avoid rapid formation of a sputtered tungsten film, by sealing the electrodes into frustoconical end portions of the envelope, or by thermally insulating the ends of the envelope with an external coating of heat-conducting paint, e.g. platinum. The lamp may comprise auxiliary electrodes, Fig. 1 (not shown). Specific dimensions, electrical data, and gas fillings are given.

[Also in Division H1] The breakdown voltage of an SCR is increased by providing the normally uncontacted base layer with an electrode to which is applied a bias voltage of such magnitude and polarity that the junctions on both sides of this base layer are reverse biased while the device is non- conducting. The bias electrode may be in the form of a ring extending round the circumference of the device, Fig. 3 (not shown), or may be attached to the centre of the base layer, the overlying base and emitter layers being apertured for this purpose, Fig. 4 (not shown). Two bias electrodes may be provided on the same base layer so that the bias voltage can be applied to that electrode lying outside the depletion layers for both polarity conditions. The cathode junction (J1) may be short-circuited. A bias supply circuit (Fig. 6) comprises a transformer 16 and a bridge rectifier 9, 10, 11, 12, which produces a D.C. voltage of suitable magnitude from the A.C. supply to the anode 1 and cathode 2 of the device 7. Two diodes 14, 15 ensure that the bias voltage applied to the bias electrode 6 is always positive (for an NPNP device) relative to the more positive of the anode and cathode electrodes. A bias supply for a plurality of series connected devices, Fig. 7 (not shown), comprises a potential divider connected across the device (7, 27), the bias electrodes (6, 26) of which are connected via diodes (28, 29, 30, 31<SP>1</SP>) to appropriate tapping points on the potential divider chain.

Abstract: 969,255 Automatic speed controL INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 1, 1962 [March 14, 1961], No. 3954/62. Heading G3R. A D. C. printed circuit motor driving a magnetic tape is supplied with forward torque-producing pulses from source 15 when the frequency of pulses from generator 19 is higher than that of speed-indicating pulses from photo-cell 23. Initially, the motor is at rest with triggers 25, 26, in the "off" stable state. A first pulse from generator 19 turns on the trigger 25 through AND-gate 27, the motor being accelerated until a pulse is generated by photo-cell 23 to turn the trigger 25 to the "off" stable state. The generator 19 and the photo-cell 23 then produce alternate pulses to turn the trigger 25 on and off until the repetition frequencies of the pulses become equaL The forward torque-producing pulses thereupon operate for periods sufficient to maintain the motor at a constant speed. The speed of the motor may be reduced by decreasing the frequency of the generator 19, a condition being reached in which an AND-gate 28 is prepared by the "off" state of the trigger 25 to pass a pulse from photo-cell 23, whereby trigger 26 is turned on. This causes the source 15 to apply reverse pulses to the motor which is braked until the speed drops below the value set by the generator 19. The trigger 25 then becomes effective to maintain the speed at the new level.
