Title: Improvements in indicating circuit
IPC: B23D36/00
Filed: 1963-03-18
Abstract: 962,530. Measuring length. GENERAL ELECTRIC CO. March 18, 1963 [April 6,1962], No. 10579/63. Heading G1M. [Also in Division B3] A system for indicating the position of an end of a movable article, comprising a radiant energy source and at least three radiant energy sensitive devices positioned adjacent the path of movement of the article, so that the radiant energy from the source which reaches the devices is determined by the position of the end of the article, signal generating means providing signals in response to energy reaching one, two, all or none of the devices, a counter to count the signals and a utilization circuit coupled to the counter, A steel strip 10 is fed by rolls 11 to a shear 13 driven by means 14, the rolls are stopped when the strip is being cut. The operation of the shears is controlled by the leading end of the strip which passes between a scanner 16 and a light source 17. The scanner 16 comprises four radiant energy or light sensitive devices 30, 31, 32, 33, on to which the light is focused by a lens 34 so that the shadow 81 of the strip moves in the opposite direction to the strip. If the leading end of the strip stops short of the light source 17 so that light falls on all four devices a gate mechanism 21 is operated to reject the cut length as too short. If the shadow of the leading end of the strip covers device 33 only then a signal is produced indicating that the strip is shorter than the desired length, but not unacceptably short. When the devices 33 and 32 are covered by the shadow, a signal is produced indicating correct length. When the devices 33, 32, and 31 are covered the resultant signal indicates a length greater than the desired length, but not unacceptably so. When all four devices are covered the gate mechanism 21 is operated to reject the cut length as too long. The first, second, fourth and fifth signals are applied to a reversible counter which indicates the net difference between the accumulations of variations in both directions. When the net difference reaches a predetermined magnitude a signal is applied to a feed length control 24 to correct the amount of strip fed by the rolls 11. A switch 25 is operated at the same time as the shear and is utilized to energize the light 17 and a control circuit 20. The control circuit 20 comprises a transistorised mono-stable multi-vibrator and four amplifier circuits each controlling a relay, and also having in its circuit one of the devices 30, 31, 32, 33 which controls the condition of the amplifier circuit by the drop in impedance which occurs when the device is illuminated.

Title: Improvements in cathode ray tubes
IPC: H01J31/34
Filed: 1941-08-25
Abstract: 551,665. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 25, 1941, No. 10847. Convention date, Aug. 23, 1940. [Class 39 (i)] In a cathode-ray tube of the type having a longitudinal magnetic focusing-field, the .effective diameter of the electron beam and the size of the resultant spot on the screen' is reduced by rejecting those electrons having a radial component of velocity exceeding 0.66 electron-volt. This is done by interposing two spaced apertured electrodes 24, 25 in the path of the beam and a formula is given relating the maximum radial velocity passed by the arrangement to the sum of the radii of the two apertures, their separation and potentials, and the length of a loop' performed by the electron in the magnetic field. The radii may be unequal, with the smaller nearer the electron gun. The apertures in electrodes 24, 25 may be of circular, rectangular or other shape. A television transmitter of the " orthicon " type is described in which electrons from a gun 3 pass through an accelerating anode 23, which may be omitted, to the two selecting apertured discs 24, 25, thence through slotted shield 10, deflecting plates 9, deflecting field 1'6 to mosaic screen 2. Owing to the immersion in the longitudinal magnetic field of coil 15, deflection occurs at right angles to the normal directions. The screen 2 is held at a potential near that of the cathode, so that the electrons approaching it with nearly zero velocity are selectively reflected in accordance with the potential distribution set up on the mosaic by the picture. The returning electrons follow the same path through field 16 through shield 11, diverge between plates 9 and, passing through slot 12 in shield 10; strike electrode 25. The magnetic field 16 may be replaced by deflecting plates, when the electrons do not return to plate 25. The screen 2 may also be fluorescent, photo-conductive or photo-voltaic. Numerical values of dimensions, spacing and potentials are given in examples. Specification 542,496 is referred to.

The clutch of a flywheel driven press is prevented from engagement until a guard 24, supported by arms 23, 41 from coaxial cams 16, 39, is in the safe position, where it is retained until the ram 4 is stationary in the uppermost position. Depression of apedal 11 causes downward movement of a rod 29 carrying a stop 31 which engages a projection 17 on the cam 16 to lower the guard 24. Further movement of the rod 29 causes engagement of a lost-motion connection 32, 33 to cause a rod 35 to release a clutch engaging stop 7, providing the cam 16 has rotated sufficiently to allow a lever 61 to drop into a notch 64 and release a lever 34 connecting the pin 33 and rod 35. Rotation of the press crankshaft moves a roller 46 from notch 48 in a cam 47 to raise a stop 44 which engages a projection 42 on the cam 39 to prevent raising of the guard 24 until the ram 4 is in its uppermost position and the roller 46 can again engage the notch 48. The relative position of the guard arms 23 and cams 16, 39 may be adjusted by bolts 18 in arcuate slots 26 in plates secured to the cams.

Filed: 1928-04-13
Abstract: 289,464. Stokes & Smith Co., (Assignees of Federwitz, T. A.). April 29, 192'7, [Convention datel. Coating machines. - Mechanism for coating sheets with adhesive comprises an applying roller associated with a member adapted to distribute the adhesive supplied to the roller by a supply member. Preferably the distributor member is cylindrical and rotates periodically in timed relation to the sheet-feeding mechanism. A suction roller 21 having a suction vent 27 is pivoted on an arm 20, attached to the carriage 5 by an arm 18 and pivot 19. The carriage 5 is reciprocated along track members 2 by means of the rock-shaft 6, lever 7 and link 9. When the carriage is approximately in the position shown in Fig. 1, the roger 21 contacts with the edge of the top sheet of a pile, supported on a vertically moving table 11, and lifts it on to the rear edge 36 of a guide 35. As the carriage 5, Fig. 1, moves to the right, the surface 37 of the guide 35 guides the sheet to a driven feed roller 38 which, when contacting with the idle roller 33, feeds the sheet to feed rollers 39, and 40, driven and idle respectively. These rollers advance the sheet from the guide member 41 to the applying roller 42 and coacting roller 43, whence the coated sheets are removed by a conveyer 44. The connection between the vacuum pump and roller 21 is operated by the movement of the carriage 5 and at a predetermined point the vacuum is broken, allowing the sheet to fall on to the guide 35. The roll 42 is supplied with adhesive from a. tank 46 in which a roller 47 dips. A scraper 50 is provided and the glue is transferred to a distributing member 51, resting against or near the roller 42. The position of the member 51 is adjustable by means of a hand-screw 56, to vary the thickness of adhesive on the roller 42. The member 51 is intermittently rotated by means of the reciprocation of the carriage 5. A ratchet 57 is attached to the shaft 52 on which is mounted the member 51. and is normally held stationary by a spring pawl 59. The teeth 58 of the ratchet engage with a pawl 59a, pivoted on a lever 60, and are maintained in engagement by a spring 61. The lever 60 is pivoted on a shaft 62 and normally pressed against a stop by a spring 64. A rod 67 connected to the, carriage 5, passes freely through an end of the lever 60 and carries movable abutments 68 which engage the end of the lever when the carriage moves to the right, Fig. 1. The lever 60 is thus moved and actuates the pawl 59a, which in turn rotates the ratchet 57 and distributor member 51. The distributing- member 51 may be in the form of an elongated polyhedron.
