Title: Machine for coining type-wheels or rollers for office machines
IPC: B44B5/00
Filed: 1971-01-19
Abstract: 1333622 Rolling ING C OLIVETTI & C SpA 19 Jan 1971 [5 Feb 1970] 2624/71 Heading B3M Characters are coined on a wheel 8, Fig. 1, by reciprocating a planar die 27, mounted on a support 26, in a directiion perpendicular to the axis of the wheel. After clamping the wheel between spindles 6 and 7, a coining pressure is applied, via piston rod 32, Fig. 3, wheel 28 and support 26, between the die 27 and wheel 8 by the actuation of an hydraulic cylinder 31. The actuation of cylinder 31 also presses wheels 41, via tie rods 37, on to the spindles 6 and 7 to balance the coining pressure. The die 27 is then reciprocated by a double acting cylinder 17 which causes the wheel 8 to rotate due to a rack 10 on the support 26 engaging a pinion 11 on the spindle 6. In a second embodiment, Fig. 6, a movable slide 51 is moved away from a fixed slide 50 against the force of springs 91 by pressurizing a chamber 95 so that a piston 82 is moved to the left as seen in Fig. 6 and forces oil in a chamber 86 through hole 87 to a chamber 88. A roller is then raised between two coining tools 58 by an hydraulic support 105 and spindles 111, slidably mounted in boxes 113, are carried inwardly to engage the roller by displacing rod 119  to the position shown in Fig. 9. On releasing the pressure in chamber 95 so that the piston 80 returns to its initial position shown in Fig. 6, a coining pressure is applied between the tools 58 and the roller by the springs 91. A cam shaft 68 is then rotated to reciprocate the slides 50 and 51, a rocking lever 73 ensuring that as one slide moves up, the other moves down.

Patent GB-871965-A (GB)
Title: Thermosetting refractory materials
Filed: 1958-01-29
Abstract: In bonding granular non-acid refractory material, which is non-reactive with calcium orthosilicate and contains only small amounts of lime, e.g. less than 3%, by the process of heating it with a small amount of, e.g. 5 to 25%, by weight, of a low-melting siliceous substance sufficient lime-bearing material, e.g. 5 to 30% by weight, is added to the mixture to ensure the presence of at least 6% lime in excess of that necessary to form calcium orthosilicate with all the silica in the granular refractory, and an overall lime/silica ratio of at least 1,87.  The amount of low-melting siliceous substance should be such as to provide at least 5% by weight of siliceous liquid when the mixture is heated to 1500 DEG C. which liquid cools and then bonds the refractory grains by reacting on further heating of the mixture with the lime present to form a calcium silicate at least as basic as the orthosilicate.  Suitable granular refractories are dead-burned magnesite and chrome ore, both 50% coarser than 20 mesh, and iron low-melting siliceous substance may be copper blast-furnace slag, phosphorus slag, calcium or calcium-magnesium silicate, which should be readily fusible, should contain alumina and iron oxide, and should be relatively coarse, e.g. pass a 6 mesh screen but be 50% retained on a 20 mesh screen; alternatively it may be fine, e.g. pass a 100 mesh screen, in which case both the refractory material and the lime bearing grains should be coarser than 20 mesh.  The presence of both siliceous fines and limebearing fines is to be avoided.  Specification 697,653 is referred to.

Title: Improvements relating to closure flanges for container wall openings, to methods forforming such closure flanges and to containers incorporating such closure flanges
Inventor: DEARING CLARENCE WILLIAM
IPC: B65D39/08
Filed: 1955-02-04
Abstract: 767,458. Making containers. AMERICAN FLANGE & MANUFACTURING CO., Inc. Feb. 4, 1955, No. 3369/55. Classes 83 (2) and 83 (4). [Also in Group XVII] Stamping.-A method of forming a closure flange for a container wall opening comprises drawing a hollow cylindrical neck up from a flat metal blank, surrounding the exterior of said neck with a non-circular formation, forcing the stock of said neck outwardly to impart said non- circular formation to the exterior of the neck and to impart a mating non-circular formation to the interior of said neck and threading the interior of said neck to form a thread therein of varying depth. The flange neck 3 is formed by cupping the blank out of which the polygonal base 2 of the flange is formed, removing the base of the cupped portion and finally opening out the neck to extend at right angles to the base. The neck of the formed flange blank is inserted into a polygonal die 6 (Fig. 6), which co-operates with a cylindrical die 11 provided with longitudinal peripherally spaced outwardly extending ribs 14, one for each corner of the polygonal die 6. The ribs are rounded off at 16 to give the die 11 a start in the flange neck when forming the polygonal portion as shown in Fig. 8. Prior to cutting the thread in the neck the end portion is reamed internally at 24 down to the upper end of the polygonal portion to allow entry of a tap to cut a thread in the segments 23. In a modification one full thread is cut above the polygonal portion to facilitate the reception of a plug. The container or drum wall is prepared for receiving the flange by forming a polygonally-flanged perforation at 31 (Fig. 9), to mate with the exterior of the closure flange neck. The flange is secured in the wall by beading the reamed upper neck portion 39 around the end of the wall neck 32 (Fig. 10). A gasket 35 is placed between the flange base and the drum wall. A plug 45 (Fig. 11), having an upper recess for accommodating a gasket 47 is threaded into the flange and a capseal 55 provided with a gasket 58 is placed over the flange and swaged over the beaded portion. The container and flange may be of composite material, e.g. stainless steel and aluminium. Flanges made of ordinary steel are shielded from the interior of the container by an overlay element 66 of polyethylene plastic, said element being threaded to receive the closure plug. In a further modification the container wall is merely perforated at 81 (Fig. 17), and a separate sleeve 82 is fitted over the flange exterior and held in place by the beading of the flange neck. The capseal is secured by crimping its skirt 92 against the exterior of the sleeve.
