Title: Apparatus for reducing the particle size of materials
IPC: B02C15/12
Filed: 1949-12-07
Abstract: 666,200. Colloid mills. MESSINGER, W. Dec. 7, 1949. [March 14, 1949] No. 31449/49. Class 59. Grinding apparatus for preparing dispersions of paint pigments in liquid vehicles such as varnishes, oils and resins, includes an inner grinding shell 16 enclosing a plurality of conical rollers 31 secured in a cage comprising top and bottom members 35 and 36 respectively, said rollers co-acting with a conical grinding head 32 formed on an arbor 33 driven through a coupling 41 by an electric motor 43. The top of the grinding head is formed with a vertical chamber 48 having radial openings 49 whereby charge material from a hopper 18 is distributed over the grinding surfaces and discharge tubes 26 receive ground material from a discharge cavity 30. The included angle of taper of the rollers 31 is one half that of the grinding head 32 enabling the assembly to fit into the cylindrical bore of the shell 16, and since the taper of the rollers and grinding head are oppositely inclined the motion between them is largely a combination of rolling and sliding or shearing. The lower cage member 36 is supported on a thrust bearing 38 having its inner race seated on a spider 28 secured between outer casing members, and a flange 40 on a collar 39 prevents ground material from collecting round the arbor 33.

Title: Improvements in or relating to shuttles for looms for weaving
IPC: D03J5/00
Filed: 1930-10-20
Abstract: 367,823. Weft feeler arrangements for stopping looms. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Crompton & Knowles Loom Works ; 93, Grant Street, Worcester, Massachusetts, U.S.A.) Oct. 20, 1930, No. 31469. [Class 142 (iii).] Shuttles.-To effect the stoppage of a loom by electrical means, the shuttle is provided with a weft detecting member 30, Figs. 2 and 5, and a slotted shuttle peg 10 each of which is pivotally mounted on a pin 15, the former being movable independently of the latter in a slot 13 between arms 11, 12, and adapted to project through a slot 36 in the cop or tube, when the weft has been substantially exhausted, thereby completing an electric circuit. A tooth 34 or a brush-like element on the member 30 is normally held against the inner coils of the weft by the action of a spring 32 on a short arm 31 at its pivoted end. When the bobbin becomes sufficiently denuded the detecting portion penetrates the last remaining coils and causes a second projection 42 to engage a spring contact 41 mounted on the underside of the shuttle. The spring 41 is electrically connected to a contact plate 43 and the pivot pin 15 is connected to a contact plate 45, both plates being mounted flush with the front shuttle wall 44 above the usual thread groove and adapted to co-operate with relatively stationary contact brushes 45a forming part of an electric circuit (not shown). A flat spring 18 secured to the shuttle body holds the spindle 10 in operative or inoperative position and serves in the latter case to bring the tooth 34 within the slot 13 when a fresh cop is being inserted. A compression spring 20 serves to hold the arms 11, 12 apart and to limit the downward movement of the member 30. The unwinding of the last few coils of weft is facilitated by providing the tooth 34 with an inclined surface 50 and by forming the slot 13 of the spindle with a pointed end. An additional opening is made at the thick end of the cop, in alignment with slot 36, to permit proper positioning relative to the slot 13. In a modified form of the detecting member an extension 60, Fig. 7, normally engages the lug of a spring contact 61 and prevents its engagement with a second contact 62 but on weft exhaustion the circuit is completed by the anticlockwise movement of the member 30 and the loom is stopped. When the spindle is tilted outwards for the insertion of a fresh cop the extension 60 engages a cam face 63 of the spring 61 and moves it outwards so that it can be held by the projection 64 of a retaining lever 65 until the inward movement of the spindle effects its release through a second lug 66.

Class 75(iii) The wick 21 of a friction lighter is pressed down into its tube 12 when the tube 12 is sealed by pressing a sealing disc 9 over its end. A tuft 20 of asbestos or glass fibre fed with fuel through the wick 21 is mounted in a cup 19 secured in the end of a spring 17 mounted in the tube 12; the upper end of the spring 17 being bent into a loop surrounding the tuft 20 and the lower end 18 of the spring being soldered to the lower end of tube 12. The sealing disc 9 of oil-proof rubber is held in a cup 11 attached to a resilient steel band lever 8 which forms the lighter cover and which is held in the closed position by a projection 15 of a leaf spring 13 which abuts a stop 14 when the lever 8 is in the open position. The lever 8 rotates a friction wheel 7 when moving to the open position.

Filed: 1955-11-04
Abstract: 775,266. Seals. BROOKS CO., E. J. Nov. 4, 1955, No. 31619/55. Class 146(2). A shackle seal comprises an elongated band 10 having a tongue 18 at one end and a hollow locking head at the other formed by folding at 12 an upper portion 14 over an opposed portion 16 of the band, and a channel clamping member 20 partially encircling the locking head containing a prong 46 to interlock with a prong 26 on the tongue 18, the prong 46 being supported by a protrusion 50 of the clamping member 20 so that if any attempt is made to release the tongue 18 by depression of the prong 46 it would be permanently bent. A second protrusion 52 prevents tampering from the lefthand end and together with the protrusion 50 forms a recess to receive the bent-down prong 46 so it can no longer engage prong 26 to relock the seal. A bent-up rib 56 on the clamping member 20 also discourages tampering.

Title: Improvements in or relating to speed controlling systems for electric motors
IPC: H02P7/26
Filed: 1945-11-23
Abstract: 604,080. Automatic control systems for electric motors. SPERRY GYROSCOPE CO., Inc. Nov. 23, 1945, No. 31676. Convention date, Nov. 23, 1944. [Class 38 (iv)] Speed.-In an automatic speed control system for an electric motor, operation of a single pair of contacts of a speed governor reverses the polarity of a voltage controlling motor torque. In the application to automatic speed control of an A.C. motor 50, Fig. 1, governor contacts 8 are open at speeds below the desired speed so that an A.C. voltage obtained from the secondary 10 of a mains transformer 11 constitutes the input to a twostage thermionic valve amplifier including a cathode phase-inversion amplifier stage 17, 18 resistance-capacity coupled to a push-pull amplifier stage 36, 37. The output of the amplifier energizes the split field 49 of -the motor, the armature 54 of which is separately energized from the mains. Capacitors 52, 53 form with the field a circuit resonant at the supply frequency. If necessary phase adjusting elements (not shown) may ensure optimum relative phase between armature and field currents for positive motor torque. Above the desired speed contacts 8 close and the phase of the amplifier input is reversed so that a negative torque is produced to brake the motor. Within the range of control contacts 8 vibrate and the energization of the motor field is dependant on the relative time of make and break, a condenser 19 forming, with the resistance of a network 1, an integrating circuit to average the input to the amplifier. In the application to automatic speed control of a D.C. motor, Fig. 2 (not shown), operation of governor contacts reverses the polarity of a D.C. input to a four-valve two-stage directcoupled D.C. amplifier the output of which energizes the motor field. In either arrangement compensation for the effect of temperature on the governor contacts may be arranged for by subjecting a temperature sensitive resistance bridge supplied with A.C. or D.C. to the same temperature variation as the contacts and including its output, which is zero at normal temperature, in the amplifier input.

Convention date, Nov. 29, 1934. [Classes 39 (i) and 40 (iii)] The concentration of a cathode ray beam is controlled in accordance with the angle of deflection so that the spot on the fluorescent screen is as sharply defined at B, Fig. 1, as at A. The cathode ray beam is correctly focused when undeflected by a solenoid H, Fig. 2, the direct current through which is adjusted by a variable resistance R1. The deflecting potentials applied to the deflecting plates E over a transformer T are also fed to a potentiometer P 1 from which tappings are taken to a push-pull rectifier G, so that a unidirectional current, varying in accordance with the deflecting potentials, flows through an auxiliary focusing solenoid Z to produce a varying component in the concentration of the cathode ray beam. The screen S may be slanting with respect to the undeflected direction of the beam.
