Filed: 1922-11-08
Abstract: 197,636. Veluard, A., (Assignee of Seymour, G.). May 12, 1922, [Convention date.]. Pile-fabric looms. - In pilecutting devices for cutting the floats of weft formed over pile wires extending in the direction of the warp, circular cutters arranged in two series one behind the other and adapted for individual removal are attached to cutter bodies carrying cutter noses connected to the pile wires. The cutters are provided with gear-wheels driven independently from gear-wheels carried on shafts which are adapted to be rotated intermittently by a belt connected to the lay. Each cutter 50, Fig. 5, is attached to a gear-wheel 52 adapted to mesh with a wheel 80 slidably keyed to a shaft 18, and is pivoted to a cutter body 57 having a recessed portion provided with a strengthened extension 64 adapted to rest in a recess in a transverse bar 15. The cutter 50 has a portion disposed between the wheel 80 and an attached guides disc 81, thereby maintaining the gears in mesh. Groups of the cutter bodies are secured to the bars 15 by clamping- blocks 68. The foot of each cutter body is provided with a pin adapted to engage a slot 77 in a cutter nose which is secured at 75, Fig. 8. to the pile wire and has a slotted bowed end 74 over which the pile floats are held taut while they are being cut by the cutter 50. Shafts 18, Fig. 4, on which the gear-wheels 80 are slidably mounted, are carried in housing-plates 20 pivoted by screws 22 to the frame of the device. The plates are normally held in an upright position by latches 28, but when it is required to remove any cutters. the plates are turned into the position shown, the cutters are unclamped from the bar, and they can be removed, the cutter noses remaining in the fabric. The shafts 18 are geared together by an intermediate wheel 40 adapted to be driven intermittently from the lay. The wheel 40 is fast on a shaft 100, Fig. 9, having keyed thereon a ratchet wheel 110 engageable by a pawl 111 on a sleeve on which is wound a band 90 connected to the lav and a flat spring 115 which is coiled in a direction opposite to that of the band. When it is required to turn the housing-plates 20 into the position shown in Fig. 4, a catch 125 engaging a groove in the shaft 100 is raised, and the shaft can then be moved longitudinally by a handle 102 to move the gear-wheel 40 out of mesh with the gearwheels on the shafts 18.

Abstract: 365,522. Making, filling, and closing cartons. HARTMANN, C. W., Lyngby, near Copenhagen. Oct. 13, 1930, No. 30608. [Classes 18 and 94 (i).] In apparatus in which a plurality of mechanisms for making, conveying, filling, and closing cartons, are arranged side by side and actuated by common driving, timing, and controlling mechanisms, the forming and filling mechanisms are intermittently connected to the common driving means. The cartons may be similar to those described in Specification 288,734, [Class 18, Boxes &c.], and the filling &c. units may be as described in Specifications 337,470 and 337,690, [both in Class 94 (i), Packing &c.]. Making cartons. The lowermost blank in a stack 1 is depressed by a suction nozzle 3, a lift valve 5 breaking the vacuum to enable a feeder 6 to forward the blank on to a pasting roller 7, which feeds it to the upper horizontal side of a former 9, about which it is folded. End folding devices 18, 19 turn down the side flaps at the end, and a pasting roller 20 applies adhesive. The remaining flaps are turned in and pressers 26, 27 ensure adhesion. The completed carton is stripped from the former and received between uprights 28 spaced so as to allow fingers 30 on an endless chain 33 to feed it towards filling mechanism 31. A plurality of such carton-forming mechanisms is mounted on a common shaft 47, the intermittent motion of which, and the actuation of the filling devices, are obtained as shown in Fig. 3. A cam 35 engages a roller 38 on a frame 39 and rocks it, thereby imparting an oscillating movement to a toothed segment 42 to which the frame is connected by a link 41. The segment meshes with a gear wheel 43 having a clutch connection with a gear 45 meshing with a gear 46 on the shaft 47. The frame 39 is also connected by a link 47a to a frame 48 having a toothed segment 50 driving gears 51 .. 54 to actuate the carton filling mechanisms 57, which are also mounted side by side, and are similar to that described in Specification 337,690. The shafts 47, 51 are engaged by their respective clutches by rods 67, 68, Fig. 8, actuated by cams 67b, 68b driven by bevel gearing 72 by the prime mover 74. After being filled, the carton arrives beneath a device 55 which turns down the two end flaps and exposes the side flaps to the action of a pasting roller 61 on a reciprocating carriage. Mechanism 76 turns down the side flaps, and the package passes between delivery bands 86. All the closing, pasting, and delivery devices respectively are simultaneously actuated, being mounted on slides or shafts common for each device.

Title: An improved method of inhibiting gum formation in low boiling hydrocarbon oils and products obtained thereby
IPC: C10L1/00
Filed: 1931-11-06
Abstract: Gum formation in low-boiling hydrocarbon oils free from iron carbonyl, e.g. cracked gasolene and naphtha, is retarded by dissolving therein a small amount such as 0,0005-0,1 per cent of one or more of the following dyes not bearing a sulphonic or thiobenzyl group: (1) Indophenols ; (2) Oxazine bases, e.g. alkylated Meldola's blue, Nile blue, Cresyl blue ; (3) Indamine bases, e.g. Bindschedler's green, Toluylene blue, Indamine base for Toluylene red ; (4) Eurhodine bases, e.g. Neutral Red ; (5) Safranine and Aposafranine bases, e.g. alkylated Safranine, Magdala Red base, azocarmine ; (6) Amino-azo bases other than spirit yellow R.  The dye may be added direct or as a solution, e.g. in benzene.  As the colour fades before the inhibiting power ceases, gum formation is prevented at least as long as the gasolene is coloured.  More dye is added as required.

Title: Television receivers having automatic gain control
Inventor: HUTTON JAMES ALAN
IPC: H04N5/50
Filed: 1955-10-27
Abstract: 797,556. Automatic gain control. MURPHY RADIO, Ltd. Oct. 26, 1956 [Oct. 27, 1955], No. 30776/55. Class 40 (5). In a television receiver with automatic gain control (A.G.C.) means are provided to prevent overload before the A.G.C. comes into operation. As applied to a receiver having a pentode 1 as last video LF. stage, followed by video detector 2, and having a beam tetrode video amplifier 3 feeding the picture tube via a cathode-follower 4, the screengrid of the tetrode 3 is fed via a series resistor 13 and constitutes the source of supply of screen-grid voltage for the I.F. stage 1; decoupling is provided by resistor 16 and a decoupling condenser. The arrangement is such that if overload occurs in the warming-up period, before the A.G.C. comes into operation, the screen-grid potential of the valve 3 falls, and by reducing the screen grid potential of the valve 1 reduces the I.F. gain.

Title: Improvements in control apparatus for navigable craft
IPC: G05D1/00
Filed: 1955-10-27
Abstract: 817,894. Automatic steering control systems. GENERAL ELECTRIC CO. Oct. 27, 1955 [Oct. 28, 1954], No. 30783/55. Class 38 (4). In a navigation system for a craft a control surface may be operated manually or by an electrical servo-system of an automatic pilot, and operation of switch means by the manual controller initiates the operation of positioning means to maintain the automatic pilot in a null condition during manual control. In the aircraft automatic pilot shown A.C. signals dependent on movement of the craft about one of its axes are derived from an inductive pick-off 30 of a gyro vertical 32 and applied to an amplifier 28 energizing a servomotor 16 which positions a control surface 10, such as the elevator or aileron, through an hydraulic system including a control valve 13 and servomotor 12. A signal dependent on rate of movement of the aircraft about the axis, derived from a potentiometer 33 operated by a rate gyro 36, and position and rate follow-up signals derived from a potentiometer 39 and a generator 25, operated by servomotor 16, are also applied to amplifier 28. The control surface may also be controlled by manual operation of a column 15 pivoted at 17 and coupled through a bracket 18 to operate control valve 13 directly. Movement of column 15 in either sense by handle 15a causes contacts 47 to be closed so that an amplifier 45, supplied with a signal dependent on movement of the aircraft about the axis, is connected to energize a servomotor 46 which adjusts an inductive device 40 to nullify the signal from pick-off 30 during manual control so that there is no opposition from the automatic pilot which is also kept in readiness to maintain the new course when handle 15a is re-centred by springs 50 on being released after manual control.

Abstract: 237,496. Lyon, H. Dec. 24, 1924. Welts.-The invention relates to a number of ways of producing a unitary beaded leather welt for boots and shoes. In some instances, the bead is integral with the welt; in others, it is fastened thereto. The welting is made up from pieces of leather scarfed together at 2, Fig. 3, in known manner. In one form, the leather is then cut along lines 4, 7 so as to produce an integral bead 8 which is folded in and cemented, as in Fig. 6, leaving the grain side of the leather outermost at 12. The inner edge 13 is left bevelled and a groove 3 is provided for the inseam stitch. The bead 8 may be stitched down by a diagonal stitch 15 parallel to the inseam. In a modification, the leather is cut as in Fig. 9, the piece 21 being discarded, a flange 20 lying as in Fig. 10 and being secured by the inseam, shown dotted. In a further modification, Fig. 12, the leather is cut to leave only a thin edge layer 104 which is used as in Fig. 14 avoiding the waste of the previous part 21. The layer 104 is secured by the inseam. Further modifications deal with non-integral beads and some with colour effects. The grain side of the leather 202, Fig. 21, is severed from the rest, and a bead 205 is cut from a side strip of the welting. The welt is used as before. In another modification, Fig. 23, a bead 219 is cut integral with the top layer 220 and folded over as in previous cases. The grain side of the beading may be coloured. In another modification, Fig. 33, the grain surface of the leather is removed and wrapped round a bead- 308 being secured by a stitch 307 and by the inseam. The stitch 307 may be made to pass through the bead 308.
