Patent GB-1085435-A (GB)
Title: Improvements relating to methods of and arrangements for doffing and donning bobbins in speedframes
Inventor: BENYON JOHN
IPC: D01H9/04
Filed: 1965-06-08
Abstract: 1,085,435. Bobbins. T.M.M. (RESEARCH) Ltd. June 7, 1966 [June 8, 1965], No. 24213/65. Heading B8M. [Also in Division D1] Bobbins are doffed from a speed frame by bringing all the bobbins and their associated flyers to rest and then simultaneously relatively axially displacing all the bobbins and flyers to cause each roving to be severed at a point between the bobbin and the presser foot of the associated flyer. In Fig. 3, the flyers are driven from overhead, and the packages are traversed by a rail, and each package is rotated faster than the associated flyer by a shaft 29 which has a clutch element 28 engaging a corresponding element in a flange 25 of the bobbin, the element 28 having a spigot for locating the bobbin. At the end of a set, the traverse-rail is lowered below the lowest point of the traverse, so that each roving is severed and each bobbin comes to rest by means of its flange 25 on a platform 36, with the top of each bobbin clear of the locating spindle 14. As the rail continues to descend, the clutch parts are separated, and the bobbin is removed by tilting and raising it. For the next set, empty bobbins are placed on the platform or the platform is removed and replaced by one carrying empty bobbins. The traverse rail is raised to start-position, in which the presser feet each bear against a plush zone (34, Fig. 5, not shown) on the associated bobbin. After the builder motion is reset, the machine is restarted at crawl speed to wind at least one coil on the zone; upward movement of the bobbin then causes the roving to be wound over the tail-end of the bobbin and the machine is accelerated to full speed. The presser foot is urged against the package by a spring coiled around the shaft of the foot, and is counterweighted. A lug on the shaft abuts a stop against the flyer leg to limit inward movement of the foot at the start of a wind so as not to impede the upward movement of the empty bobbin. The arrangement may be applied to a machine where the flyers are traversed as described in Application No. 3394/65. The machine is stopped when the presser feet are moving downwards and at a predetermined distance from the foot of the bobbin, provision being made to bring the presser feet to a stop at the rear of the machine. With the machine stopped, the traverse rail is moved downwards to break the rovings. Each bobbin is mounted on a spring- loaded driving platform, and the bobbins are depressed manually to disengage them from the associated locating-spindles such as 14.

Abstract: 170,727. Mooney, D. J., and Brown, E. E. Aug. 23, 1920. Struts.-Cross stiffeners for spars &c. for aircraft are made of thin metal, which is bent in such a way that the stiffeners have curved or bent backs and fit the shape of the spars &c., and the metal is not drawn or stretched. A metal blank shown in Fig. 1 is bent along the dotted lines and produces a stiffener, shown in elevation and side view in Figs. 2 and 3, having a convex back d. Stiffenens with concave or other backs may be produced in a similar manner from differently-shaped blanks. Fig. 16 shows a spar consisting of upper and lower channels f connected together by bent stiffeners c. Other spars are described with side members which are stiffened by members c either inside, as in Fig. 19, or outside, as in Fig. 21.

Abstract: 307,702. Tourne, C. March 9, 1928, [Convention date]. Addition to 273,293, 278,317; and 280,496, [Class 39 (ii), Electric lamps, Incandescent]. Vacuum tubes. - In lamp bulbs and thermionic valves of the kind described in the parent and associated Specifications, wherein mechanism is placed within the bulb to enable a succession of new filaments to be laid in position without opening the bulb, the travelling filament gripper is opened by an arm 103 that rides on a pivoted cam 106, and the stationary gripper 3 that holds the filament 1 near the end of the tube 16 which conducts it from the supply reel 15 is opened by a pivoting movement of the cam. As the gripper 2 approaches the gripper 3 the arm 103 is rocked by the cam and opens the gripper 2 and then allows it to close on the filament behind the gripper 3, and during the return movement the arm 103 rocks the cam to open the gripper 3 to allow a new length of filament to be pulled out. In the construction shown, which is applied to lamp bulbs, the rotation of an iron bar 14 by means of an external magnet causes the gripper 2 to lay the filament in a circular path, as described in Specification 292,616, [Class 39 (ii), Electric lamps, Incandescent]. In a modification (Figs. 21 to 25, not shown), the gripper 2 is adapted to lay the filament in a straight line axially of the bulb, as in a thermionic valve.

Abstract: 1507918 Automatic deslagging of cupola furnace CENTRE TECHNIQUE DES INDUSTRIES DE LA FONDERIE 6 June 1975 [27 June 1974] 24512/75 Heading F4B A cupola furnace has an automatic deslagging device comprising a passage 9 in the hearth area leading to a siphon 16 having an overflow 17. Prior to tapping as shown in Fig. 1, pig iron 7 is at its maximum level 12 and due to the pressure of slag in the furnace is level in the siphon with the overflow 17. After tapping from the tap hole 4 is completed, and as shown in Fig. 3, a thin layer of pig iron is left and slag fills the siphon 16. When blasting is continued pig iron accumulates again as shown in Fig. 5, and as its level rises, slag in the siphon 16 is poured over the overflow 17. Thus automatic deslagging occurs during regular pig iron tapping operations.

Abstract: 865,219. Digital data storage apparatus. KIENZLE APPARATE G.m.b.H. Aug. 2, 1957 [Aug. 2, 1956], No. 24565/57. Class 106 (1). An array of storage elements is so arranged that shift along at least two co-ordinate axes is selectively possible. Four magnetic cores forming part of a matrix are shown. Each core, e.g. core 60, contains four windings x, y, u, v for transmitting data in the indicated directions, a shift winding 120, and an input winding 70. Each winding x, y, u, v is normally maintained at a negative potential by being connected to an associated bus-bar. In operation shift of stored data in a selected one of the four directions is effected by pulsing every shift winding simultaneously with a positive pulsing of the bus-bar of the selected direction, the shifted data being temporarily stored on capacitors associated with the input windings before being finally stored in the adjacent cores. Other circuits are described which are alleged to perform various computing functions. Specifications 848,953 and 863,814 are referred to.

Title: Improvements relating to thermionic valve oscillators
IPC: H05B6/50
Filed: 1945-09-25
Abstract: 600,496. Automatic control systems. FERRANTI, Ltd., and WOOD, H. Sept. 25, 1945, No. 24794. [Class 38 (iv)] [Also in Group XL (c)] The loading of a valve oscillator is maintained constant by adjusting means under the control of a voltage derived from the difference between voltages developed across separate resistors in the anode-cathode and grid-cathode circuits, respectively, of the oscillator. In an application to a dielectric heater, the material 7 is placed between the plates of capacitor 3 in the tuned circuit of a push-pull oscillator 1, 2, and the separation of the plates is controlled automatically by the split-phase motor 17 with oppositely connected field windings 16, 21. The potential at tapping 15<SP>1</SP> relative to earth controls the current delivered to winding 21 by valves 23, 24 and equals the difference between voltage across resistor 18 due to anode current flow and the voltage across part of potentiometer 15 and field limiting resistor 20 due to substantially constant grid current flow. Tapping 15<SP>1</SP> is adjusted initially to balance the currents in the two windings 16, 21 for the loading conditions determined by the setting of potentiometer 14. A change in loading alters the anode current through resistor 18 and the fields of windings 16, 21 become unbalanced, operating motor 36 to restore the original conditions. Spring-loaded multiple switch S1-ABC enables the plates of capacitor 3 to be adjusted by the motor when the oscillator is de-energized, and switch S3 allows the oscillator to function without control. The common grid circuit may include a barretter and the armature may be braked by eddy currents, viscosity or from a coupled D.C. generator supplying negative feedback to the grids of valves 23, 24. Alternatively, the motor may control a variable capacitor in series with capacitor 3, an inductive component in the tuned circuit or the H.T. voltage for the oscillator.
