Title: Reversing mechanism for regeneratively-heated coke-oven batteries
IPC: C10B21/14
Filed: 1957-04-15
Abstract: 864,019. Thermal regenerators. KOPPERS G.m.b.H., H. April 15, 1957 [April 20, 1956], No. 12181/57. Class 64(1) A reversing mechanism for regeneratively heated coking chamber ovens having flaps 6 for controlling the inflow of combustion air to the regenerators comprises a draw bar 17 which engages, by means of an impelling device 19, a setting lever 16 rigidly fixed to a bell crank 14 to open the flaps in response to movement of the draw bar in the direction of arrow 18 whilst movement in the opposite direction allows the flaps to close by gravity. The impelling device comprises an element which is clamped to the draw bar and to which is pivoted a rocking member 24 which is recessed at 25 so that it embraces the upper part of the draw bar whilst engaging the setting lever 16. The rocking member may be swung through 180 degrees to an inoperative position 24a and has a length equal at least to the operative movement of the draw bar so that when it is in an inoperative position the associated flap remains closed. The flow of gas from a rich gas conduit 1 is controlled by the draw bar 11 operating valves 4.

Abstract: 592,469. Circular looms; shuttles. COOPER, H. J. May 16, 1945, No. 12275. [Classes 142 (ii) and 142 (iii)] In a circular loom, rollers 22, 23, mounted on a rotary conveyer 2 engage with rollers 20, 21, on each shuttle 19 to drive the shuttles through the warp shed, and the rollers 20, 21, are also supported by rollers 11, 12, mounted on rotary shafts 8, the shuttles being supported solely by the rollers 11, 12, 22, 23, and the arrangement being such that the bottom warp threads 18 pass between the shuttles and the supporting rollers without having their position or tension materially disturbed. Co-operating grooves and ribs on the rollers 11, 20, respectively prevent axial displacement of the shuttles. Magnets 25 provided on the conveyer 2 prevent the shuttles separating from their supporting rollers. Some or all of the rollers may have a yielding surface. Each shuttle is provided with a beat-up disc 34 and carries a rotatable bobbin 29, the weft thread being guided by a member 35 which may be provided with fur or tensioning wires.

Title: Improvements in overspeed and overwinding prevention gear for winding engines
IPC: B66B5/08
Filed: 1925-05-12
Abstract: 255,579. General Electric Co., Ltd., and Lindley, A. L. G. May 12, 1925. Stop-gear.-A centrifugal governor a for controlling the speed of a winding-engine is driven by a motor b through a differential gear c which is also connected with the winding engine. A gear g. formed on the casing of the differential gear meshes with a gear h on a shaft i driven by the winding engine and connected by bevel gears to a shaft z. One end of the shaft z is in threaded engagement with a fixed nut 11, and the other end is squared and passes through a correspondingly shaped aperture in the gear 12. A toothed wheel y mounted on the shaft z during normal running does not come into contact with a catch plate m secured to a shaft x. Arms 15, 16 on the shaft x are connected by links 17, 18 with slotted ends to a pin 19 secured to one arm of a bell-crank lever, the nose 23 of the other arm of which engages one arm of a three-armed trip lever 24, 25, 26 pivoted at 27. The arm 25 is weighted and the arm 26 is connected with' a throttle valve, brake engine, or other controlling element of a winding-engine. The shaft x is carried by arms w depending from a shaft v provided with an arm u. A pin t on the arm u engages the slotted ends of rods r, s pivoted to the arms o, p of a three-armed lever n, o, p. The arm n engages the collar k of the governor. When the engine overspeeds, the movement of the collar k causes the plate m to be thrust against the rotating wheel y and consequently the shaft x to be rocked and the trip mechanism actuated. If the engine is running at full speed and the driver fails to retard at the correct point, the plate m will be in an advanced position and the wheel y will engage one end of the curved ends 14 of the plate and cause the actuation of the trip mechanism while the cage is still a considerable distance from the banking level. Overwinding is prevented in a similar manner.

Abstract: 253,339. Lyons & Co., Ltd., J., and Coyte, W. A. May 14, 1925. Machines for lining boxes. Cardboard &c. boxes for butter, ice cream, &c. are lined with blanks of cruciform shape, and the flaps of the blanks are bent outwards and downwards so that the tops of the boxes remain quite open during the subsequent filling operation. The boxes 10 are inserted in the machine with their rear closing- flaps under guide-rods 72, and, as they are fed along intermittently by projections 48 on an endless chain, lateral guide-rods 64, 65 engage and hold down the side closing- flaps. When a box comes to rest beneath a lining blank supported on members 26, 27, a plunger 2 carried by a vertical reciprocating rod 6 descends and presses the blank into the box, the members 26, 27 moving away from one another to allow the plunger 2 to pass between them. Inclined side plates 139 press down the side flaps of the lining and cause them to pass below the guide-rods 64, 65, and another inclined plate 139<a> presses the rear flap of the lining down against the corresponding closing- flap of the box. At the front of the box where there is no closing-flap, the flap of the lining is pressed against the outside of the vertical wall of the box by a lever acting in conjunction with the plunger 2.

Title: Improvements relating to flat warp knitting machines
Inventor: PORTER ALLAN WILLIAM HENRY
IPC: D04B27/06
Filed: 1959-04-16
Abstract: 889,739. Knitting-machines. HOBOURNF.N.F. Ltd. April 4, 1960 [April 16, 1959], No. 12998/59. Class 74 (2). In a warp knitting machine sinker, that part of the neb projecting beyond the throat 7 is divided into two tips 5, 6 which are face to face and diverge towards their extremities. The parts diverge at equal angles from a central plane containing the remainder of the sinker, which is made from two resilient plates 1, 2 fixed together face to face in one of blocks 9 which are cast around them and bolted side by side to a sinker bar. The tips 5, 6 of each sinker touch those of their neighbours and the spacing of the front ends of the sinkers is maintained by a rod 14 passing through holes 13 in them. The arrangement causes the thread 25 to pass behind and under the tip 5, say, of a sinker when an associated needle is taking yarn in successive courses from the same guide eye in the formation of open loop pillars: thus the sinkers hold these loops down effectively as the needles rise. In addition, when a guide eye laps its yarn around a needle, the resulting thread helix runs from the top edge 30 of the plate 1, say, instead of from the last knitted loop 27<SP>1</SP> in the fabric; and so the helices are laid into the needle hooks at a relatively shallow angle and can pass into the hooks more quickly as the needles move downwardly, so reducing the tendency to mislapping. Specification 889,738 is referred to.
