Title: Easy-opening closures
IPC: B21D51/00
Filed: 1974-06-27
Abstract: 1450855 Easy-opening containers; internal stopper BROKEN HILL PTY CO 27 June 1974 [27 June 1973 12 July 1973] 28593/74 Headings B8D and B8T [Also in Division B3] An easy-opening closure in a sheet metal can end comprises an aperture closed by an inwardly-displaceable closure member 1; the overlapping edges of the closure member and aperture having inter-engaging means, which include a burr or lip 7 on one or both edges of a height no greater than half the thickness of the sheet metal end and which inhibit lateral movement between the closure member and aperture to prevent damage to a joint sealant S or bursting open of the closure. The closure member may be a separately-formed member, but it is preferably sheared from the end itself except for a small integral hinge portion. As shown, a bulge 6 is initially formed in the end. The closure member is then pinch-sheared from the bulge between a co-operating die D and punch P, the latter having a 45 degree chamfer which forms an upstanding lip 7, and simultaneously displaced downwardly. The remaining aperture defining rim portion is then partially flattened and turned down into engagement with the lip. In a modification, Figs. 5 and 6 (not shown), the shearing operation also forms a dependent lip 9 on the aperture edge, which lip is engaged with the closure member lip on flattening of the bulge. In another modification, Figs. 7-9 (not shown), a lip on the closure member is engaged in a groove or score 11 formed in the aperture edge. Alternatively, the lip may be formed on the aperture edge and the groove in the closure member. Instead of the overlap being formed by flattening the remaining portion of the bulge after shearing, the closure member may be flattened or the closure member and/or aperture edge coined, grooved or stretched to form an overlap.

Title: Improvements in and relating to apparatus for use in the manufacture of cigar bunchesand cigars
IPC: A24C3/00
Filed: 1938-08-19
Abstract: 518,409. Cigar-making machines. INTERNATIONAL CIGAR MACHINERY CO. Aug. 19,1938, No. 28682/39. Convention date, Jan. 5, 1938. Divided out of 518,199. [Class 130] Transfer mechanism includes a cigar or bunch holding or gripping device supported by an oscillatory arm, capable of swinging between receiving and delivery positions, the holding device being maintained in an upright position during the movements of the arm by shaft and gear drive enclosed in the arm. A pedestal 141 supports racks 140, 149 reciprocated from the main cam shaft of a wrapping machine. With this may be combined either short or long bunch making machines from which bunches are transferred to the wrapping mechanism by arms 23 while arms 11 pass on the wrapped cigars to a re-rolling drum. The movement of the rack 149 is transmitted through a pinion 264 and shaft 265 to the hub of the arm 11. As this moves, an enclosed bevel wheel 270 gearing with a bevel wheel fixed in the bearing rotates the shaft 269. Further bevel gearing 275 connects shaft 269 to a shaft 276, the opposite end of which is secured to the holder 277 of the bunch or cigar grippers 157. If the bunches are to be turned through an angle in transit bevel gearing is also .introduced between the end of the shaft 276 and the gripper holder. Arms 23 are similarly actuated from the rack 140 and pinion 282. Should the grippers 157 fail to lift a bunch or cigar, the superposed lever 150, Fig. 4, remains in a tilted position as indicated in dotted lines. Its end then fouls a projection 152 from a rod 154 the turning of which closes a switch 158. By means of an associated solenoid 161, Fig. 12, an obstruction 164 is drawn in the path of a lever 125 which normally lifts a suction head to pass a wrapper to transfer mechanism. The circuit of the solenoid includes a timing switch responsive to a cam on the main cam shaft of the wrapping machine, so that the switch is closed at a definite point in the cycle of operations.

Abstract: 883,061. Machinery guards. RATCLIFFE, A. Oct. 6, 1958 [Sept. 12, 1957], No. 28743/57. Class 80 (4). A guard or cover 10 of a machine such as a textile carding machine cannot be opened or removed whilst the machine is running by reason of a projection 44 on an arm 38 secured to the guard or cover 10 having to move into the path of a toothed member 28 rotating with the machine. When the machine is stopped the member 28 may be moved by reason of a lostmotion drive coupling from the machine shaft 20 to allow the passage of projection 44 and the opening of the guard or cover. The lostmotion coupling may also effect an axial movement of the toothed member 28 on the shaft 20 when the latter is running so that a shoulder 36 engages under an open-topped bearing bracket 18 to prevent the shaft being lifted. In a modified arrangement a facial undulating surface on a rotating member co-operates with a sliding bolt for locking the guard or cover in closed position.

Title: Improved method and apparatus for the detection of eccentricity or wobble of rotatable bodies
Filed: 1955-10-13
Abstract: 792,066. Electric tests. GENERAL MOTORS CORPORATION. Oct. 13, 1955 [Oct. 25, 1954], No. 29181/55. Class 37. Dimensional irregularities such as eccentricity or wobble in a rotating ferromagnetic body (e.g. a helical gear) are detected by obtaining electrical signals representative of the variations in the space between the surface of the rotating body and a fixed reference line parallel to the rotational axis at a pair of axially spaced positions on the reference line near the ends of the body and then combining said signals. Apparatus for carrying out this method comprises inductive pick-ups 18, 20 (Fig. 1), consisting of a coil surrounding a permanent magnet, carried by an arbor 10 so that the tips of the pick-ups are disposed in a line slightly spaced from the surface of a helical gear 14 on a rotating shaft 12. The pick-up coils may be connected separately or in series aiding or opposing to a cathode-ray oscilloscope, or the combined signals may be fed through amplifiers and a rectifier to two thyratrons biased to cut off at different levels, hence indicating by lamps in their anode circuits two different discrete levels of irregularities. The amplified, combined signal is also fed to one half of a differential amplifier incorporating a double triode valve, with a relay coil interconnecting the two anodes, the resultant voltage from the pick-ups for a standard helical gear being sufficient to energize the relay, thereby closing the thyratron supply circuit and lighting a further indicator lamp. The lamps may be replaced by counters, thereby determining the number of good, medium and bad articles tested.
