Title: Improvements in or relating to machines for winding wire
Inventor: BULL CABOT SEATON
IPC: B21F17/00
Filed: 1954-11-16
Abstract: 790,423. Coiling wire grids. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 16, 1955 [Nov. 16, 1954], No. 33113/54. Class 83 (4). A machine for winding wire around a support includes step-by-step mechanism for intermittently moving said support along a rectilinear path during rotational movement about the support of a head carrying the winding wire. Support wires 4, 5 for a grid electrode of an electron discharge device, are clamped at 15 to a threaded shaft 14 given an intermittent longitudinal movement by an internittently rotated nut 17, the shaft 14 being prevented from rotating by a key 16a. A winding head 8 carrying a spool 9 of fine wire is continuously rotated by a shaft 13 around the support wires 4, 5 to wind the wire thereon, each step movement of the shaft 14 and support wires being equal to half the pitch of the grid, the supports being at rest while they are notched, and as the fine wire is passed over one of them, and moving longitudinally as the head 8 carries the fine wire from one support wire to the other. The nut 17 has ratchet teeth engaged by a pawl 21 on a pivoted arm 19 rocked by a cam 23 on the shaft 13 and is held after each ratchet movement by a latch 20 on the arm 19 engaging peripheral teeth in a wheel 17a secured to the nut 17. Alternatively, Fig. 3, an oscillated carrier 27 has a claw 29 which moves the nut 17 and a claw 28 which completes such movement and positions the nut 17. The nut 17 may be driven through escapement mechanism.

Title: Improvements in or relating to signalling apparatus for use on motor vehicles
IPC: B60Q1/34
Filed: 1931-11-30
Abstract: 389,913. Road-traffic signals on vehicles. RANCE, A., 110, Totteridge Road, and BARTLETT, A. E., 152, London Road, both in High Wycombe, Buckinghamshire. Nov. 30, 1931, Nos. 33158/31 and 1295/32. [Class 118 (ii).] Front and rear manoeuvre-signalling lamps 1, 2, 3 and 6, 7, 8 together with tell-tale lamps 10, 11, 12 are controlled by (a) a main switch 14, (b) a flashing switch 37 for the rear lamp 7, and (c) a brake-actuated switch 45. The circuits are such that the rear central lamp 7 is illuminated whenever any " right " or " left " signal lamp is illuminated. By depressing the switch 37, one circuit for the lamp 7 is interrupted at contacts 39, 41, and " flashing " is effected by an alternative circuit intermittently completed at contacts 49, 50. When the brake is applied, for example with the vehicle at rest, the switch 45 cuts out the lamp 7, although the flashing switch is in its normal outward position. The front signal casing, Fig. 3, comprises coloured windows 60 in lamp covers 59 having a bayonet-joint connection with a chamber 58. The main control switch 14 is operated by a warded key which is removable when the switch is in the position in which current is cut off from all the signal lamps and from the entire ignition system.

Class 112 Differential work-feeding mechanism in a sewing machine comprises a rocker arm 30 journalled in the bed 1 of the sewing machine about an axis 23 parallel to a feed shaft 7, operative connections for imparting oscillation to arm 30 upon rotation of shaft 7, a horizontal main feed bar 34 pivoted at 31 to arm 30, operative connections for imparting feed lift movements to bar 34 upon rotation of shaft 7, an auxiliary feed bar 39 slidably carried on the main feed bar 34, a lever arm 55 journalled in bed 1 about an axis 63 parallel to shaft 7 and below the level of arm 30, operative connections for imparting oscillation to arm 55 upon oscillation of arm 30, a link 52 connecting arm 55 to the auxiliary feed bar 39, and means for adjusting the connection 59 between link 52 and arm 55 relatively to the pivot axis 63 of the latter to vary the feed advance movements imparted to bar 39. A radially adjustable crank pin (not shown), on the end of shaft 7 is connected by a link (not shown) to an arm (not shown) rigid with shaft 23 for oscillating the latter. An arm 72, rigid with shaft 23 and arm 30, is connected by a link 69 to an arm 66 rigid with arm 55. Link 52 is pivoted at one end at 50 to a block 43 fixed to the auxiliary feed bar 39, and is pivoted at its other end at 59 to a block slidable in a curved slot 57 formed in arm 55 and centred on pivot 50. A link 74 connects link 52 to one arm 76 of a double-armed lever pivoted at 78 in bed 1. The other arm 80 projects outside the bed and is coupled to a treadle or the like for varying the position of pivot 59 in slot 57 to adjust the stroke of bar 39. The latter is slidable in lugs 38 on bar 36. The stroke of both feed bars is adjusted by varying the position of the crank pin on shaft 7. An eccentric 81 on shaft 7 carries a sheave 83 on which is slidably mounted an arm 86 fixed in adjusted position by screws 87. Arm 86 is pivoted at 89 to a lug 91 depending from bar 34 for imparting feed-lift movements thereto. The main and auxiliary feed dogs 35 and 40 are carried by respective pins 36 and 41 which are fixed in bars 34 and 39 respectively, and are adjustable longitudinally and angularly therein.

Title: Methods of forming glass layers on substrates
IPC: H01G13/00
Filed: 1962-08-29
Abstract: A method of forming a glass layer on a substrate comprises centrifugally depositing a layer of glass particles on to the substrate from a fluid having a dielectric constant of between 3.4 to 20.7 and containing finely-divided glass particles in colloidal suspension, removing the substrate from the fluid and then fusing the glass particles on the substrate.  A suitable glass, chosen according to the physical and chemical properties required for the resultant glass layer, is ball-milled and the resultant powdered glass is introduced into a suspending fluid, for example methyl alcohol, dispersed by ultrasonic agitation and the larger and smaller sized particles removed from the suspension by differential centrifuging. The remaining medium sized particles are dried on a hot plate or in a desiccator and resuspended in an organic fluid or mixtures of such fluids having a dielectric constant as above.  The resuspended glass particles are deposited on to the substrate by centrifuging, the substrate removed from the suspension and, after drying, the substrate is heated to fuse the glass particles to form a thin uniform film thereon.  A suitable centrifuge is described and illustrated.
