Title: Twist drill sharpener
IPC: B24B3/24
Filed: 1965-05-10
Abstract: 1,038,272. Grinding drills. E. V. MITCHELL. May 10, 1965, No. 19694/65. Heading B3D. Apparatus for supporting a twist drill 26 for grinding by a grinding wheel 20 comprises a chuck 28 releasably supported for rotation and axial movement in a first collar 30 rigid with an arm 54 which is mounted for compound pivotal movement about a pivot 64 parallel to the axis of the grinding wheel and at substantially the same elevation and a pivot 58 normal to the pivot 64 on a base 22 movable toward and away from the periphery of the grinding wheel, a second collar 42 carried solely by the chuck for free rotation and axial movement on the chuck, means for clamping the second collar on the chuck, and co-operating means 78, 80 on the collars for permitting the chuck to rotate 180 degrees when the first collar is released. The base 22 is movable on guides 23, 27 in a direction normal to and parallel to the axis of the grinding wheel and supports a vertical post 62 in which is the pivot 64 for a flange 60 of a support member 56, Fig. 2 (not shown). A slot in the support member adjustably receives the pivot 58 for the arm 54 carrying the first collar 30 which can be clamped to the chuck 28 by a member 40. The second collar is clampable to the chuck by a member 52 and has a cut-away 78 which extends over more than 180 degrees by an amount corresponding to the width of a projection 80 on the first collar, the cut-away and projection comprising the co-operating means for permitting 180 degrees rotation of the chuck when the first collar is released. A position gauge 72 is carried by a graduated member 74 in a support on the member 56 to determine the setting-up position of the drill. When a drill is to be sharpened, the arm 54 is adjusted about the pivot 54 to obtain the desired cone angle of the drill and is secured in position by tightening a nut. The point of the drill is adjusted to a position determined by the setting of the gauge 72, the latter being set so that the point projects a distance beyond the axis of the pivot 64 corresponding to the-desired relief to be ground on the drill. When the point of the drill has been set, the member 40 is operated to tighten the first collar 30 on to the chuck and the second collar is moved to abut the first and is tightened by operating the member 52. The first collar 30 is then loosened while the chuck is rotated until one of the cutting edges of the drill is horizontal and is then re-tightened. Thereafter the second collar is loosened and rotated until the projection 80 engages one end of the cut-out 78. One side of the drill is then ground by advancing the base 22 to bring the drill into contact with the wheel 20, the arm 54 carrying the drill being swung about the pivot 64. After the first side has been ground, the collar 30 is loosened to permit the chuck to be rotated 180 degrees to a position determined by engagement of the projection with the other end of the cut-out for grinding the other side of the drill.

Patent GB-438068-A (GB)
Title: Improvements in and relating to change-speed gear control
IPC: F16H63/14
Filed: 1934-07-09
Abstract: 438,068. Gear-changing mechanism. ALLTREE, A., Rydal Dene, Pilling Lane, Preesall, near Fleetwood, Lancashire. July 9, 1934, No. 20024. [Class 80 (ii)] Gear-changing mechanism in which the gears are pre-selected prior to the actual change, as described for example in Specification 402,924, comprises a shaft 1 which on being turned in one direction disengages the gear in use by means of a cam slot 1<c> in the shaft co-operating with a pin 4d on a pivoted lever 4 which operates a sliding fork 5 and clutch member 6 co-operating with gears 9 and 11. Movement of the shaft 1 in the other direction effects the actual gear-change by means of one of the link bars 7, 8 pivoted on the shaft 1 which engages and pulls down one end of a cross-bar 4a, 4b of the lever 4 to slide the clutch 6 into engagement with either the gear 9 or 11. The link bar which is operated depends upon the position of a pre-selector shaft 2 with slots 2<a>, 2b which allow the selected link bar to move into engagement with the end 4a or 4b of the lever 4. Automatic pre-selection of the next gear in sequence is obtained by coupling the shaft 1 to a pawl carrier 20, Fig. 4, freely mounted on the shaft 2 and witha pawl 20a co-operating with ratchet teeth 2d on the selector shaft 2 so that on movement of the shaft 1 to neutralize the gears the selector shaft 2 is given a partial turn to select the next gear in sequence, which is then engaged by the return movement of the shaft 1. A cam member 22, Fig. 6, may be provided on the shaft 2 so that the pawl 20a may be lifted and the automatic pre-selection dispensed with, this cam being operated from the manual pre-selector lever 26, Fig. 14. As shown in full lines, the lever 26 controls the selector shaft 2 through a hollow rod 26d, but when raised to the dotted position the rod 27 actuates the cam 22 for automatic operation, the lever 26 then being free to move with the shaft 2. Automatic pre-selection may be obtained on both upward and downward changes by means of a double pawl and ratchet arrangement with a cam member to make either pawl operative as desired for either up or down changes or to make both pawls inoperative for manual selection. The mechanism is equally adaptable for the operation of sliding type gears or the brakes of epicyclic gears.

Title: Method and device for the felting of sliver and such like into felted yarns
IPC: D06B3/02
Filed: 1975-05-13
Abstract: 1505162 Felting yarns and slivers I W S NOMINEE CO Ltd 13 May 1975 [16 May 1974] 20171/75 Heading D1F A moistened sliver or yarn 38 containing keratin fibres is felted by passage through a flexible guide tube 26 which is flexed. Preferably the tube is caused to execute a wave motion. The wave may be a standing wave and the tube a straight tube subject to a reciprocatory flexing motion through a crank or cam. Preferably however a travelling wave is produced by the action of rollers 14 mounted between rotating end plates 12. The yarn or sliver is thus drawn through the tube and felted by the peristaltic action. The tube is of silicone rubber or a tightly coiled helical spring. It has a cross-section of 5 to 60 m<SP>2</SP>/ktex of sliver. A false twist may be applied before the yarn or sliver is moistened with felting solution 36. Wool and wool/polyester blends are specified. When used in cut pile carpets the yarns do not lose their identity as separate yarns during wear.

Title: Improvements in and relating to systems of frequency modulation
IPC: H04B14/00
Filed: 1930-07-03
Abstract: 364,603. Valve modulating circuits. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Dome, R. B.; 13, 9th Street, Schenectady, New York, U.S.A.) July 3, 1930, No. 20204. Convention date, July 22, 1929. [Class 40 (v).] In a system of frequency modulation a relatively low constant carrier frequency is varied in accordance with signal amplitude and at a rate dependent on signal frequency, the frequency-modulated carrier frequency being multiplied until the sidebands are raised above audibility; the amplitude modulation component is simultaneously suppressed. The oscillator 5, oscillating at the frequency of the tuned circuit 6, derives its anode voltage from the battery 7 through the choke 8. The signal from the microphone 11 is passed on to a modulator 9, the corresponding anode current variations through the choke 8 producing variation in high tension supply to the oscillator 5. As the oscillator frequency varies with anode voltage a mixture of frequency and amplitude modulated energy is present in the output circuit of valve 5. This energy is passed to a series of saturated frequency multipliers 17, 18, 19 having tuned anode circuits 20, 21, 22, each tuned to a harmonic of the grid circuit frequency. By this means the amplitude modulation is removed due to the saturation of the amplifier, while the sideband frequencies are simultaneously raised above audibility.

Abstract: 1,260,704. Screw-and-nut mechanisms. INTERNATIONAL BUSINESS MACHINES CORP. 23 April, 1969 [22 May, 1968], No. 20758/69. Heading F2Q. Coarse axial adjustment of a probe 1 may be effected by manual rotation of a knob member 8 when it is held in an axially extended position, shown in Fig. 2A, against the action of a spring 41, to cause disengagement of a clutch 7, 39, and fine adjustment may be effected by rotation of the knob member 8 with the clutch 7, 39 engaged. The knob member 8 carries drivepins 10 which engage axial slots 45 in a tubular member 4 which has a relatively coarse screwthreaded engagement with a support member 5. A sleeve 3 is slidably and rotatably mounted within the tubular member 4 and has a relatively fine screw-threaded engagement with the probe I. The sleeve 3 carries at one end a clutch part 39 and a closure cap 6 which is urged by a spring 42 into engagement with a thrust ball-bearing 12 carried by the tubular member 4. The probe 1 is prevented from rotating by a plunger 53 which engages a keyway 51 in the upper surface of probe 1. A pin 13 limits axial movement of the probe 1. When the clutch 7, 39 is engaged the screw threads act differentially. Two such probe mechanisms are used at right angles to accurately position a workpiece such as a semi-conductor wafer.
