Title: Improvements in or relating to frangible elements in sheet material
Inventor: COOKSON WILLIAM
IPC: B21D51/38
Filed: 1968-02-16
Abstract: 1,262,272. Opening containers by tearing. COOKSON SHEET METAL DEVELOPMENTS Ltd. 6 Feb., 1969 [16 Feb., 1968; 24 Jan., 1969], Nos. 7698/68 and 4248/69. Headings B8D. [Also in Division B3] A weakened line is formed in a container end wall by pressing it between a top die 36 having a step 64 and a bottom die 40 having a step 66 offset inwardly of the step 64 so as to form a portion 24 of reduced thickness in the wall which may be easily ruptured to open the container. The top die is formed with a bead 47 which cooperates with a recess 60 in the bottom die to produce the bead 30 in the container wall which accepts the material extruded from the reduced portion 24. The formation of the bead 30 commences prior to the formation of the reduced portion 24. The portion 24 may be annular so as to define a tear out panel 26, and the top die has a recess 74 to accommodate ears 70 and a reinforcing bead 116 which are formed prior to the forming of the weakened portion 24. The ears are subsequently used to secure a handle 120 (Fig. 8) to the tear-out panel by being clenched on to tabs 78 which are hingedly connected to the handle which is formed with a nose 122 for puncturing a reduced portion 112 (corresponding to portion 24) on upward pivoting of the handle. Lifting the handle shears the remainder of the reduced portion 112 with minimum bending of the tear-out panel 106. A reinforced shoulder 110 may be formed at the periphery of the wall and forms a safe edge for the inside of the container when the panel 106 has been removed.

This transfers the refuse on to a conveyer 11 the downstream end of which rests on a ledge 39 at the bottom of a feed opening (5) (Fig. 1) of the second vehicle. The conveyer 12 has a ramp 32 for receiving the wheels of the first vehicle, and has sides 26, 30, which are retractable (Fig. 8, not shown). The conveyer 11 also has retractable sides, and in use is covered by a resilient sheet 19, so as to completely enclose the refuse. The conveyers and ramp 32 may be folded up to provide a trailer (Fig. 6, not shown) connected to the vehicle 2. The positioning of the conveyer 11 relative to the opening 5 of the vehicle 2, may be adjusted by control elements (not shown) responsive to movement of the wheels of the first vehicle on the ramp 32. The to and fro movement of the conveyer 11 relative to the vehicle 2 may be adjusted by a jack 45 (Fig. 11) which operates on telescopic portions of a connecting stay 36. Similarly the inclinations of the conveyer 11 may be adjusted by a jack 47.

Abstract: 601,520. Drills and cutters-bars. CLARK, R. H. Feb. 22, 1945, No. 4500. [Class 83 (iii)] A tool for cutting holes in sheets, plates and the like comprises a number of cutters carried by a body, projecting forwardly and outwardly from the body and angularly with respect to radial planes passing through the tips of the cutters and the body axis, the outer ends of the cutters being dressed so that the angles between the leading faces of the cutters and the said radial planes vary. The body portion 10 of the tool, with which the shank 11 may be integral or screwed thereto, is of hexagonal section with alternate faces slotted at 18 to take the forwardly and outwardly extending cutting tools A, B, C. The tools are clamped in adjusted position, according to the diameter of hole to be cut, by set bolts 12 and clamping washers 23. The leading faces 27 of the cutting tools are arranged at an acute angle 2. Fig. 2, to the radial planes passing through the cutting points and the axis of the body, and in one cutter this angle is reduced by an amount Y on the operative portion of the cutter to prevent chatter. The tips 31 of all the cutters are ground back to reduce the tendency to dig in. The pilot portion 13 may be secured to the body by a wedge-pin or by a set-screw and for use in setting the cutters an auxiliary pilot with a cut-away face corresponding with the axis of the complete tool may be employed. In an alternative arrangement the tools A, B, C are replaced by cutter bars and cutting tools are adjustably clamped in position at the ends of the bars.

Abstract: 307,056. Goodyear Tire & Rubber Co., (Assignnes of Junior, S. S. K.). March 2, 1928, [Convention date]. Drawings to Specification. Indiarubber, attaching to metals.-A salt of copper or cobalt is applied to the surface of the metal or the rubber, which is then vulcanized in position under heat and pressure. Organic or inorganic salts may be used, for example oleates, stearates, palmitates, chlorides. They may be applied as a dry powder, as a solution or dispersion in benzene, or rubber solution, or in an artificial resin varnish. Adhesion may also be obtained by using a rubber cement containing copper or cobalt salts of mercaptobenzothiazole. In an example, steel is coated with a solution of copper or cobalt oleate in benzene and then with rubber solution. A layer of raw rubber containing fillers, sulphur and accelerators is then pressed on the coated steel, previously moistened with benzene, and the whole is vulcanized at a temperature corresponding to 40 lbs. steam pressure.

Filed: 1959-02-11
Abstract: 880,615. Brackets. IGRANIC ELECTRIC CO. Ltd. Feb. 11, 1959, No. 4759/59. Class 52(5) [Also in Group XXV] In a fitting of the type in which an electric lamp or other device is supported by means of a pivoted arm, a C-shaped spring is incorporated in the pivot joint to resist but not prevent pivotal movement. Preferably friction means are also included in the pivot. The device 1 is supported by an arm formed in two pivotally connected parts 3, 5 joined to a swivelling base plate 7 by a pivot according to the invention. The base plate 7 carries a U-shaped member 10 having arms 11 formed with pinion teeth 12, and a similar member 13 having arms 14 is secured to the lower lamp-carrying arm 5. Pivot pins 16, 17, journalled in the arms 11, 14 respectively, are held a constant distance apart, so that the teeth are in mesh, by means of a pair of plates 18, 19 threaded on to the pins and separated by spacers 20, 21. Bushes 22, 23, are threaded on to the pins on each side of the joint, which is symmetrical, and over the bushes are threaded a friction plate 24, spring washers 25, 26, and a plate 27 formed with bosses 28, 29 extending beyond the bushes. The friction of the joint is adjusted by a nut 30, screw threaded on to the pin 17 to abut the boss 28, and a nut 31 screw threaded on to the pin 16 to abut a shoulder inside the boss 29. The boss 29 has two radial projections 33 located, when the joint is assembled, on either side of a stop 34 on the base plate 7, and a C-shaped laminated spring 9 is passed over the boss so that its ends engage the opposite sides of the projections and the stop. When the arm 5 is inclined in either direction from the vertical the plates 27 on each side of the joint, together with their bosses 29, turn through half the angle in the same direction, and the projections 33 are moved out of alignment with the stops 34 to stress the springs. A cover 35 is provided on each side of the joint. The spring may act throughout the whole movement of the arm, or a lost-motion may be provided between the spring and the projections and stop so that the spring is inoperative over a range of positions of the arm.

Title: Improvements in and relating to the drying of tubular skins of regenerated cellulose
IPC: F26B21/00
Filed: 1933-02-18
Abstract: <PICT:0410931/IV/1> In the process of drying a tubular skin of regenerated cellulose by passing the skin A through a drying atmosphere while maintaining it in an inflated state, the passage through the drying atmosphere is effected by means of a conveyer, which surrounds the skin and confines it to the desired cross-section. The wet skin A is withdrawn from the roller B by rubber coated rollers C, D and conveyed through a drying tunnel E. The conveyer comprises two chains each comprising a number of semi-circular units F connected by links G, and each travelling on a guide rail H round toothed sheets J, J<1>.  The links F are perforated and lined on their inner surfaces with wire gauze. Needles L puncture the skin as it passes through the drying tunnel, and are connected by air holes N to an air duct O fed from a source of compressed air P so that the tube is inflated as it passes through the drying chamber.  The needles are preferably so spaced that one perforates the tube just as the one in front of it is being withdrawn.  The tube may be inflated by attaching a small flexible pipe, connected with an air supply, to its end, and leading the skin for a considerable distance, say 200 feet before cutting it and reattaching the air pipe to the end leaving the conveyer. Specification 410,930 is referred to.
