Abstract: 571,823. Abrasive articles. ABBEY, A. (Carborundum Co.). July 12, 1943, No. 11309. [Class 60] . A resilient abrasive article such as a wheel, belt, block, or pad, consists of fibrous material which incorporates bonded abrasive grains and is arranged as by winding or folding in superimposed layers secured together, or edge-on to a flexible backing, by adhesive. Adjacent layers may be held apart at their edges by interposing spacing strips of lesser width. A flexible wheel may be formed by winding a long strip 9, Fig. 4, of the material around a bush or arbor 11, the turns being held together without a backing by interposed adhesive, or by a layer of adhesive securing them edge-on to a flexible backing 10 as of hydrolysed fibre, paper, cloth, or metal sheet. The adhesive already present in the material to bind the abrasive grains may be used to secure the layers together. A belt may be formed by folding a similar strip 12, Fig. 5, back and forth across a backing 13 to which the edges of the strip are secured by adhesive. The fibrous web material may be produced as described in Specification 555,640 by feeding a number of thin .carded fibrous membranes from carding assemblies into superimposition on to a moving endless support, distributing thereon abrasive grains from hoppers spaced along said support, incorporating a binder in the web, consolidating the web to the desired density, and finally curing or setting it. The grains may, alternatively, be mixed with binder and applied to the web by rollers ; or 'they may be projected into the web from one or both sides before applying the binder. In the formation of the web, the fibres may be interlocked by gentle gaseous agitation of the thin carded membranes as described in Specification 557,038. The abrasive may be carbide of silicon or boron, diamond, fused aluminium oxide, flint, corundum, emery or rouge. As adhesives, there may be used animal glue (preferably containing up to 40 per cent of a plasticizer such as ethylene glycol, dibutyl phthalate, or glycerine), shellac, phenol-formaldehyde or urea-formaldehyde resins, casein, rubber and latex cements, sodium silicate, or magnesium oxychloride cement.

Class 123(1) A pressure tank consisting of a cylindrical body 1 movable horizontally by means of a hydraulic ram motor 6 on rollers 3 travelling on rails 4 is closed by a stationary cover 2 supported from the rails by an "A"frame 15, the cover being provided with the necessary inlet and.outlet connections 19, 21, &c. and the tank and cover having co-operating locking means. The tank rim has an external reinforcing ring 30 to which is welded a sealing ring 32 provided with an external groove 34 to receive a resilient gasket 36. Welded to the ring 30 are spaced lugs 38 having outturned flanges 40. The rim of the cover 2 is likewise provided with an annular sealing ring 42 having an outwardly extending end portion which surrounds the sealing ring 32 with slight clearance so that the ring gasket 36 is slightly compressed as the tank is closed, see Fig. 17. Locking lugs 44 are welded at spaced intervals around the ring 42, the intervals being such that the lugs 44 will slide between and beyond the flanges 40, see Figs. 9 and 11, leaving a space between opposing faces of the lugs 44 and the flanges. Mounted for rotation on the cover is a locking ring 46 of thickness equal to the space between the lugs and flanges and having inwardly projecting lugs 48. The lugs 48 are of less length than the cover lugs 44 but of greater length than the spaces between them so that when the cover is in the closed position partial rotation of the ring 46 by a handle 56 brings it to a position wherein each lug 48 bridges the corresponding space between adjacent lugs 44, see Fig. 13, thus preventing withdrawal of the flanged. tank lugs 38. 40. In a modification, the seal between the cover and tank is made by means of a resilient L-shaped gasket having a. lip which engages the end face of the cover ring.

These are all raised periodically by a stirrup fixed to the shaft 25, which is oscillated by an arm 29 thereon and a cam disc 28. When the stirrup descends, certain needles 26 enter perforations in a perforated endless paper pattern band on a cylinder 19 and the corresponding wires 21 (or 22) move selected needles 5 (or 6) into inclined positions. The other needles remain in vertical position and when the movable bars 8, 9 fall are held raised by fixed bars 20 having vertical webs against which the needles 5, 6 are pressed owing to the eccentric disposition of the needles 3, 4. Certain hooks 1 are thereby held raised and others are allowed to fall on to the lifting knife 2. The cylinder 19 is rotated intermittently by a ratchet wheel 18 actuated by a cam 17 and two pick readings occur for each feeding movement. The bars 8, 9 for the needles 3, 4 for the lower and upper hooks 1 respectively are actuated alternately, and the dobby causes correct releasing of the sheds of previous picks when worked backwards, if the card cylinder is previously reversed two picks or if instead of feeding the cylinder and reading the pattern &c. whilst the lifting knives 2 are crossing, these actions are timed to occur during the last motion of these knives the dobby will work correctly backwards without previously adjusting the cylinder 19. A modification is described wherein the fixed bars 20 are dispensed with and the moving bars only raise selected supporting needles. Modifications are also described wherein springs 40, Fig. 6, are interposed between the needles 21, 22 and the supporting needles 31, 32.
