Title: Textile winding machine
IPC: B65H67/04
Filed: 1976-03-04
Abstract: 1489352 Textile winder; donning and doffing bobbins N SCHLUMBERGER & CIE 4 March 1976 [11 April 1975] 08634/76 Heading D1J In a textile winding machine, a slubbing bobbin is held against a drive roller by two arms mounted to rotate with a first wheel about a horizontal axis, an inextensible flexible band passing over the first wheel, over a second wheel coupled to a rotary, reversible, brakeable motor, and over a tension roller movable by control means into active and inactive positions, the arrangement being such that when the tension roller is in the inactive position and rotation of the second wheel is blocked by the motor winding and manual intervention in the winding are possible by formation of slack in the band, whereas when the tension roller is in the active position, rotation of the second wheel in one direction permits dropping of a full bobbin and replacement with an empty bobbin, and in the other direction provides for moving the empty bobbin into the winding position held against the drive roller. Bobbin 1, Fig. 1, is rotated by roller 2 and carried between two arms 5 pivotable with shaft 8 and toothed wheel 14. Chain 13 passes over toothed wheels 14, 15, rollers 17, 18, and tension roller 19 mounted on pivoting arm 22. Shoe 27 on the arm engages bladder 28 connectible to source 33 of fluid or to discharge conduit 34. As the package grows, Fig. 2, arms 5 pivot upwards, creating chain slack 13B and moving the roller 19, shoe 27 pressing and emptying bladder 28 connected to conduit 34. When the package is finished, bladder 28 is expanded by source 33, Fig. 3, and wheel 15 is rotated by motor 12 (Fig. 1) to rotate arms 5. When package 10 is above bin 38, arms 5 are separated, e.g. by pneumatic means, and the package falls into the bin. Further rotation of arms 5 enables a bobbin 1 to be picked up from guide 41, Fig. 5. The motor, which is braked when stationary, is then reversed so that the new bobbin is placed in the Fig. 1 position. Bladder 28 is then deflated, and winding started. The deflated bladder enables manual intervention at the bobbin during winding, allowing the bobbin to be raised as in Fig. 7. The chain may be replaced by a preferably notched belt, and the bladder by other means. A multi-station winder may have a common shaft 11 and bladder 28.

Title: Improvements in and relating to alumina
IPC: C01F7/428
Filed: 1956-03-20
Abstract: Alumina of higher than average pore size and high surface area, above 50   diameter and 300 square metres/gram respectively, is prepared by treating aluminium amalgam with an aqueous medium containing an organic colloid at above 80 DEG  C., separating the hydrated alumina so formed and calcining it at a temperature below that at which a -alumina is formed.  The colloid may be tannic acid or starch in amounts up to 2.5 per cent by weight of the aqueous medium, which is preferably water and may contain catalyst components.  In an example small pieces of high-purity aluminium were immersed in 0.1 N HCl for 3 hours and then an equal weight of mercury was added.  After 1 hour excess mercury and acid were decanted off, the amalgam rinsed with water, and then reacted with 0.5 per cent w/w aqueous tannic acid or starch at 95 DEG  C.  The alumina hydrate was dried and calcined at 550 DEG  C. for two hours. Average pore diameters ranging from 66 to 78   and specific surface areas from 300 m2/g to 366 m2/g were obtained. Specifications 815,512 and 815,514 are referred to.

Parcelling by bundling. - In a machine for automatically binding bundles of varying sizes, the bundles are successively engaged by spaced followers on a feeding- belt and conveyed thereby along the bed of the machine into proper position with relation to knotting mechanism. The bundles B, Fig. 1, are introduced to a feeder E by a conveyer D comprising endless chains 27 with members G<1> comprising links 125, 126 pivotally connected to each other, and to the chains at 125<a>, 126<a>, respectively. The feeder E is of similar construction, and the members G thereof advance the bundle to the position shown in Fig. 13, partially wrapping the binding-wire about it. The feeder is actuated by a segmented rack 48 nn the shaft 51, which engages a pinion 47 on a shaft connected by sprocket-gearing to a driving shaft of the feeder. The needle N descends to the position shown in Fig. 13, carrying the wire completely round the bundle and into engagement with a knotting-mechanism K. The needle comprises an L-shaped arm 29, pivoted on a shaft 30 and operated by cams C, C' through the medium of crank arms 53, 53a connected to arms R, R<1> by links 54, 54<a>, the cams being so shaped that the needle rests for a predetermined period in each extreme position. The knotting and severing operations having been completed by the engagement of the segmental rack 48 with a pinion 57, the bundle is pushed by succeeding bundles on to a delivery conveyer 67. The wire W is tensioned by a sheave A, Figs. 1 and 6, comprising a disc 36 with an annular flange 37 surrounded by a spring-pressed ring 38, the whole rotating about a stub axle 33. The wire passes from the sheave A through guide members 31<b> and over pulleys 31, 31<a> to the extremity of the needle. The power shaft 52 is adapted to be moved in or out of engagement with the shaft 51, which controls the conveying, binding, and knotting mechanism, by a lever L, which is operated automatically through a link 92, by the entry of a bundle to the machine. The movement of the lever L is not sufficient to throw out of gear the driving-mechanism which operates the delivery conveyer 67, which rotates continuously.
