Abstract: 1,030,407. Making closures for can ends. CONTOP Inc. Nov. 23, 1962 [Nov. 24, 1961], No. 44418/62. Heading B3A. [Also in Divisions B2, B4, B5, B6 and B8] Can end blanks are supplied in pairs on guide members 391, 417, 418, forming part of a reciprocable shuttle, to pairs of dies, the first pair 532, 533 embossing instructions on each blank and the second pair, which are compound dies, Fig. 34 (not shown), having parts arranged to cut interrupted lines and a tear tab, and to form embossed ribs on the blanks. The die plate 525 of the first pair is vertically reciprocable on posts 361 by means of gearing 492, 495, and a shaft 497 with an eccentric end 500. The compound dies, to which the shuttle next delivers the pairs of blanks, have each a male die 566 and a vertically reciprocable female die 604. The male die 566, Fig. 35 (not shown), has a cutting edge 570 interrupted at 571, cutting edges 572, depressions 574, and a U-shaped cutting edge 575 within which a pressure pad 580 is urged upwards by a spring 594. A member 596 has a dished upper surface for forming a rib on the tab of the finished closure. The pad 580 strips the can end blanks from the male die. The blanks may be formed of steel, aluminium or plastics material. Punching and forming fragible sheet.-Vertically reciprocable dies 1283, 1284, Fig. 73, cooperating with die rings 1405, 1406 cut out discs from aluminium foil or thin gauge plastics sheet drawn through the die mechanism by means of reciprocable grippers 1042, Fig. 65 (not shown). An upper die plate 1280 is cam-operated through a lever 1313 to rise and fall in timed relation with an intermittently rotated turret mechanism comprising a pair of castings 1580, 1581 each carrying a radially reciprocable chuck 1600, Fig. 88 (not shown). Bores 1410, 1411 in each die are connected to a source of fluid pressure, thereby enabling the cut-out discs to be forced from the dies into the waiting chucks. Stripper rings 1300, 1302 force the residual sheet from the dies. Each chuck, after further rotation to a position B, Fig. 85 (not shown), acts as a female die against which a male die 1750, Fig. 104 (not shown), operates in order to form the disc with a central depression and a peripheral flange. The face of the chuck is perforated as at 1621 and is connected to a source of vacuum by means of a fitting 1555, the vacuum thereby holding the cut-out disc in position and stripping it from the die 1750. As the chuck rotates further towards a 6 o'clock position, the vacuum is cut off and fluid pressure is applied to the chuck interior to release the formed disc.

Title: Means for controlling the supply of combustible gas and incorporating gas valve means
IPC: F16K31/68
Filed: 1975-12-18
Abstract: 1535714 Valves CONCENTRIC CONTROLS Ltd 18 Dec 1975 [16 Oct 1974] 44745/74 Heading F2V Means for controlling the supply of combustible gas comprises a flame-failure device having a gas valve and a hollow probe 29 communicating through a duct with the interior of an expansion chamber 27, 28, the probe, duct and chamber, containing a liquid which expands on being heated, the gas valve comprising a valve member 17 movable between a closed position and at least one open position, and a by-pass 25 which normally allows gas to flow at a relatively slow rate when the valve member is closed, and closure means 37, which is inoperative when the chamber 27, 28, of the flame-failure device is expanded, but which becomes operative as the expansion chamber contracts to move valve member 17 to its closed position, if not already in that position, and to close the by-pass 25. The gas valve comprises a manually rotatable plug with a cam track which moves a rod 11 axially to urge a beam 16 against an abutment 20 carried by an expansion chamber 21, which is connected to an oil-filled temperature-actuated probe, by an oil-filled tube 22. Valve closure 17 is urged to close a seat 23 against the action of a blade spring 19, by a spring 18, and by the action of chamber 21. A corrugated diaphragm 27 is actuated by the liquid-mercury-filled probe 29 when the latter is heated by a pilot burner, to cause a lever 33 to pivot and override a spring 38, so that closure 37 moves upwardly to open by-pass 25 and a reduced amount of gas passes to the main burner through inlet 24. If the pilot burner is extinguished, spring 38 operates to close valve member 17 and also by-pass 25. The gap supply to the pilot burner may be controlled by the plug which moves rod 11.

Title: Device for transferring the bobbin of a braiding machine between two adjacent horndogs
IPC: D04C3/18
Filed: 1970-09-22
Abstract: 1323709 Braiding-machines E M HERZOG 22 Sept 1970 [23 Sept 1969] 44982/70 Heading D1C In a braiding machine the bobbin spindles carry a gripper arm 23 with which they engage the horn dogs 13, 14 in turn, and which are rotated to effect a smooth transitor between one dog and the next. The bobbin is engaged with a transferring dog 13 by the claw 24 of the gripper arm engaging a projection 21 on the dog. A block 34 is fixed to the end of each bobbin spindle 19 and is slidable transversely of a guide piece 31. The guide piece carries two rollers 32 which engage in a track 29. As the spindle moves between the points 26 and 27, and the leading roller 32 moves onto the track below the next dog 14, it is decellerated and is no longer rotating at point 27. The bobbin is accelerated to the velocity of dog 14 as it passes to point 28. Since the spindle is at a greater distance from the dog axis than the projection 21 it is moving at a greater linear velocity. Thus the claw 24 moves away from the projection 21; and similarly the claw 25 is able to engage the projection 22 on the next dog.

The front corners of the guard are pivoted to uprights 122, 123 telescopically received in lower uprights 119, 120 the uprights being telescoped by an hydraulic ram assembly 32, 34. The rear of the guard is mounted by pivotally interconnected members 24, 26 which cause the rear edge of the guard to pivot upwardly about the front edge as the front uprights are telescoped. Each upright 22, 23 carries a chain 44 which meshes with a respective sprocket 38 carried by a shaft 36 mounted on uprights 19, 20. A safety means control circuit, Fig. 4, includes a switch 64 an upright 19 which is opened as upright 22 is lowered and a switch 52 on the fork mast which opens when the fork is raised above a predetermined height. With both the fork and guard lowered switches 62 and 64 are respectively closed and opened and a relay 78 is energized to close relays RC1, RC2. To raise the guard a selector switch 74 is moved to the left actuating a guard raise solenoid 84 and allowing hydraulic fluid to flow through a valve to the hydraulic ram assembly. When the guard is raised pressure in the ram assembly opens pressure switch 76 to de-energize solenoid 84. The fork may now be raised by closing switch 86 energizing a valve controlled by solenoid 88 and a lift pump solenoid 92 connected to switches 52, 64. As the fork goes above a predetermined height switch 52 opens but solenoid 92 remains energized since switch 64 is closed with the guard raised. With both fork and guard raised switches 52, 64 are respectively open and closed hence the guard cannot be lowered since solenoid 96 cannot be energized until the fork is lowered to close 52. The fork may be operated whilst switch 64 remains closed. When the guard is lowered switch 64 opens and, the fork may only be raised to the height at which switch 52 opens.

Abstract: 1318957 Disposable diapers GEORGIAPACIFIC CORP 7 Oct 1970 [8 Oct 1969] 47702/70 Heading A3V [Also in Division B2] A disposable diaper has pressure sensitive adhesive applied to the area around some or all of its corners, with adhesive releasing agent, which does not stick to the adhesive, applied to different areas of the diaper in such positions that when the diaper is folded, or when a number of diapers are stacked together, the areas of adhesive come into contact with the areas of releasing agent. Adhesive 16, 17, may be applied to two adjacent corners 26, 28 on one face of the diaper and adhesive 21, 22, to the other two corners 27, 29 on the opposite face, and a coating of releasing agent may be applied in strips 18, 24, located at opposite ends and on face of the diaper opposite to those carrying the adhesive. Colour coding may be used to indicate which areas of adhesive are brought together as shown in Fig. 4 when a number of the diapers are stacked together flat the adhesive areas lie against the releasing agent areas so that they do not stick to one another. Since the adhesive used will stick to an area of plain surface of the diaper to which no adhesive has been applied, it need only be applied in two of the corners instead of all four, either to adjacent corners or opposite corners, and to the same face or to opposite faces, with the releasing agent applied to appropriate positions. The diaper comprises an absorbent layer sandwiched between a liquid permeable body contacting layer and an outer impermeable barrier layer of material such as polyethylene sheeting. For storage and packing the diaper may be laid flat, folded in half, or folded in box pleat configuration. The adhesive may be made from for example natural rubber, butadiene and isoprene polymers and copolymers, polyisobutylene, polyvinyl ethers, polyesters, The releasing agent may be for example a hydrophobic polyvinyl carbamate having nitrogen bonded hydrocarbon side chains, a copolymer of a higher alkyl acrylate or methacrylate, a higher acyl polyalkylenepolyamine, and stearato chromic chloride, alone or combined with a water soluble phenolic resin. The release agent may be applied as a thin coating having a thickness of the order of .000 inches, from a volatile solvent or dispersing agent.
