Title: Improvements in or relating to sewing machines
IPC: D05C7/00
Filed: 1925-05-02
Abstract: 255,955. Bleachers Association, Ltd., and Evans, J. May 2, 1925. Grant of Patent opposed. Universal-feed sewing-machines; starting. -The direction of stitching and the operation of the needle-bar are controlled by synchronously moving cams which are readily detachable from the machine, the cams controlling the needlebar operation serving to stop this automatically at the end of a stitch' group and when re-entrant angles are being turned. The stitching mechanism of usual type is supported on a base below which is mounted a wheel 10 carrying on its upper face a cam-plate 17 on which is an edge cam 18 for controlling the direction of stitching and a number of face cams 19 for starting and stopping the needle-bar. The wheel 10 is driven by gearing, from the shaft 16, including a worm 11. A cam-follower 20 carried by an arm 21 bears on the cam 18 and transmits its movements to a sliding bar 24 pressed forward by a weight 25. The movements of the bar are transmitted to the needlecarrying mechanism 39 by a rack 27 on the bar 24 and gearing including members 28, 30, 34, 36, 28. The cams 19 engage a lever 41 connected by a link 43 to a sliding rod 44 which operates trip mechanism 45 of known type for starting and stopping the needle-bar. The lever 41 may be manually depressed by a control-lever 46. The shaft 12 of the worm 11 is carried in bearings pivotally mounted at 50 so that it may move to disengage the worm from its wheel. The shaft is moved into position by a handle 54 and is held therein by a catch 56 which may be released by a handle 55 to allow the worm to move away from the wheel to the extent allowed by a stop 52.

Abstract: 864,316. Gear-gauging apparatus. NATIONAL BROACH & MACHINE CO. April 11, 1958, No. 11592/58. Class 106 (2). [Also in Groups XXII and XXIV] Gear treating or checking apparatus comprises a rotatably mounted gear-like member 14 with which a succession of work-gears 10 are required to mesh, and drive means connected to the member 14 by coupling means, Fig. 3, operative upon blockage of the member 14 to transmit a torque in one direction which increases to a predetermined maximum and thereafter to transmit a torque impulse in the opposite direction. A master gear 14 rotates and a second master gear 16 may be either rotatable or fixed. The gear 10 to be tested or treated rolls along a shoot 12, and if one of the master gears 14, 16 is displaced, it is prevented from passing to a further machine which may be either a finishing machine or an accurate gauging machine. The gear 14 is driven through the slipping clutch shown in Fig. 3. The motor (not shown) drives the members 34 and the drive is transmitted by the square shaft 28. If a work gear 10 should jam between the master gears 14, 16, the clutch slips and when the members 34 have turned through slightly more than 45 degrees relative to the shaft 28, the springs 42 act to apply a reverse torque to the shaft 28 thus reversing the direction of pressure between the gears 14 and 10 and freeing the gear 10. Other geometrical figures, such as a triangle, may be used instead of the square shaft 28, and the use of a cam with only one lobe is also envisaged.

An electromechanical stepping device, comprises a shaft 7 which is rotatable about its axis, an escapement 23, 24 arranged to control rotation of the shaft, a triggering device 2 which is arranged to co-operate with the escapement, and a clutch 3 (Fig. 2, not shown) which can be driven by a motor 1 to apply a driving torque to the shaft 7, the arrangement being such that when the clutch is driven continuously a continuous driving torque is applied to the shaft, and electrical pulses received by the triggering device cause the shaft to be permittted by the escapement to rotate in respective steps. Fig. 1 shows an asynchronous motor 1 driving one half of a clutch by means of gears 18, 19. The clutch, which may be a friction or hysteresis clutch has one half coupled to the ouput shaft, while spokes on an escapement wheel 23 which is also fixed to the shaft engage with a pallet 24 to prevent rotation of the shaft. When a pulse is applied to triggering device 25, 26, 27 the pallet is moved to allow a stepped rotation of the output shaft. The pallet comprises a fixed magnet which is attracted to appropriate poles produced on arms 26, 27 of the triggering device by the pulses, and may have two rest positions as shown, or only one rest position. A direct-current or alternating current motor may be used or an electrically wound spring- driven motor may be provided.

Title: Improvements in or relating to apparatus for detecting temperature
IPC: G01K1/02
Filed: 1968-03-11
Abstract: 1,269,931. Measuring resistance. BRENTFORD ELECTRIC Ltd. and M.G.J. FRY. April 10, 1969 [March 11, 1968], No. 11787/68. Heading G1U. To measure the resistance R of an unknown resistor 11 through which a direct current I is passing, a signal proportional to the current I is applied to a first resistor R I , a signal proportional to the voltage V across the unknown is applied to a second resistor R V  and either the first or second resistor R I , R V  is adjusted to maintain the ratio of the voltages across them constant. The unknown resistor 11 may be a coiled electric cable which is to be heated and dried before the application of a plastics insulation, the amount by which the first or second resistor R I , R V  has to be adjusted providing an indication of the resistance, and hence temperature, of the cable. The signal proportional to the direct current I is derived by a direct current transformer arrangement 12 having a primary circuit constituted by the current-carrying conductor 8 and a secondary circuit comprising a pair of oppositely-wound windings connected in series with an A.C. source 16 and a bridge rectifier 14 supplying the resistor R I . The signal proportional to the voltage V is derived similarly (13). The ratio of the voltages across the resistors R I , R V  is maintained at unity by connecting the two resistors in series and automatically adjusting R I  to keep the difference voltage V r  zero. A relay 26 operates every time the difference voltage V r  reaches a threshold level to cause a motor or solenoid device S to adjust resistor R I  by one step, and the number of adjustment steps made is counted to provide an indication of temperature change. The count may be indicated by electronic indicator tubes, or by stepping switches which may also be arranged to operate auxiliary circuits when particular counts (temperatures) are reached. Resistor R I  includes a part R 4  pre-set in accordance with ambient temperature, and a resistor R 1  in series with transformer 13 is pre-set in accordance with the initial cable resistance.

Title: Methods and apparatus for testing the individual activities of probe bodies that have been irradiated, for example in a nuclear reactor installation
IPC: G01T3/00
Filed: 1968-03-11
Abstract: 1,209,826. Reactors. SIEMENS A.G. 11 March, 1968 [11 March, 1967], No. 11833/68. Heading G6C. [Also in Divisions G1 and H5] The activities of probe bodies which have been irradiated, e.g. in a nuclear reactor, are measured or tested by arranging them in a file in a conveyer tube 2 adjacent to which an activity evaluating device 1 is disposed and moving the bodies in turn past the device by the controlled movement along the inside of the tube of a wire 4, one end of which acts against the end of the file. Preferably the probe bodies are spherical and are moved through the radioactive environment and into the conveyer tube 2 by means of compressed gas. As shown in the Figure, the probe bodies 3 may be stacked in a column resting on one end of the wire which is preferably moved downwards. The wire 4 may be resilient, and movement of the wire may be induced by its being wound round and secured to a drum 40 at the end of the conveyer tube, the drum being rotatable about axis 42 to initiate movement of the wire. The wire may occupy a groove which extends helically round the drum and the drum is mounted, e.g. on threads 43, so that during rotation of the drum, it is moved transversely parallel to the axis of rotation so that the take-off point of the wire 4 always remains directly beneath the tube 2. Low friction devices e.g. rollers 44, may be arranged around the drum to hold the wire in position. The apparatus may be used for testing the flux density of a nuclear reactor.
