IPC: B21D51/32
Abstract: 133,985. Adams Pressure Tool Co., F. E., and Adams, F. E. Sept. 16, 1918. Capsules and the like, applying.-A seaming or like machine for applying ends to the bodies of cylindrical or like canisters and containers made of metal paper &c., is constructed in such a manner that sufficient energy is stored in the driving mechanism and rotary work-support to carry the body past positions in which great resistance is experienced, and the seaming tool is carried by a slide which is moved to operative position by a cam, set in motion by tightening a pulley and band drive, which remains in operation for a given period, after which the band is automatically slackened. The work table is mounted on ball bearings, and is moved into operative position by means of toggle mechanism. The container or box &c. is mounted on a table 2, which is held by a screw 20 to a shaft 21, the table rotating about the screw 20 and upon the ball bearings interposed between it and a bearing member 24 fixed to the shaft. The table is raised and lowered by toggle mechanism comprising an actuating lever 31 on a shaft 26'to which is fixed a bifurcated lever 25 forming one element of the toggle. The other element comprises a sliding bolt 27 with a rounded head 30 which bears on the shaft 21. The bolt 27 passes through a pivot 28 mounted in the ends of the lever 25, and a spring 29 is interposed between the pivots 28 and the head 30 thereby allowing a little play to the head 30 when the toggle is straightened to raise the work table. The seaming tools 15 are carried in a slide 16 operated by levers 18 and.cams 38 on a shaft 37 which is driven by worm gearing 41, when a shaft 36 mounted in an arm pivoted about the shaft 37, is driven by tightening a normally slack belt which passes over pulleys 39, 40 by the depression of a treadle 33. This causes a bell-crank 34 to act on a cam 35 to tighten the belt, and the bell-crank 34 is automatically held by a catch 43 until the shaft 37 has completed one revolution when a pin releases the catch 43 and the belt is thus slackened. The drive for the chuck 1 is from a pulley 6, jockey pulley 7, and a heavy pulley 8 which functions as a flywheel and stores energy. The pulley 8 is mounted as shown in an overhanging portion 12 of the framework and it drives the chuck 1 through speed-reduction gear 10, 11. The table 2 may be made heavy in order to store energy when rotated.

In an ultrasonic pulse-echo flaw detector for inspecting a revolving body in a manner such that the formation and behaviour of flaws under centrifugal stress conditions may be studied, the pulses are transmitted at intervals such that each pulse is reflected from the same point within the body. In the embodiment of Fig. 1, the transmission of a pulse from a single transmitter-receiver transducer 4 is synchronized with the rotation of the body, 5, by means of an electrical pick-up device 1 and a phase-shift controller 2. Controller 2 permits the transmission of a pulse at any angular position of the body 5 relative to a fixed point 8 of the body 5. Echo pulses from a flaw 6 are fed to an indicator 3, and a stroboscope 9 may be coupled to the controller 2. Coupling fluid is fed to the transducer 4 through piping 7. To enable flaw echoes to be received at high rotational speeds of the body 5, when the distance between the transducer 4 and flaw 6 is large, or when the transducer 4 has a small diameter, two transducers 4 may be used (Fig. 2, not shown), the transducers being circumferentially spaced on a circle coaxial with the axis of rotation of the body 5. Provision may be made for moving the transducer(s) 4 circumferentially.

Abstract: <PICT:0390660/III/1> <PICT:0390660/III/2> <PICT:0390660/III/3> In an apparatus for the production of ozone, the electrode system is divided into two sections, having central channels 8<1>, 8<2> leading to a central collector and outlet pipe 9 for the ozone.  Each section consists of alternate high and low pressure electrodes 4, 5, of the plate type, separated by glass dielectric sheets 6 between which is a passage 7 for the air to be treated, which passes radially from the periphery of the electrodes to the central passages 8<1>, 8<2>, being led in by pipe 19<1>.  The electrodes consist of hollow bodies through which a cooling liquid such as water is circulated, and are suspended freely from bars 13, the ends of which bear on channel members on the upper part of the frame.  The bars 13 are free to move, thus facilitating the easy removal and accurate spacing of the electrodes.  Insulators 11 are inserted in the supports of the high-pressure electrodes.  Each assembly of electrodes is pressed together by adjustable wedges 17<1>, 17<2>.  The low-pressure electrodes are cooled by water flowing from the distributing pipe 25 through the pipe 27 and inlets 20 to the electrodes, then through outlets 21 and pipes 39 to the discharge pipe 61.  A flow control device in the circuit consists of a glass cylinder 40<1> into which the water flows from pipe 61 through orifices 41<1>, 41<2>, 41<3>.  A blade overflow, preferably of triangular cross section, may replace the orifices. The water from the cylinder discharges into the pipe 61<1>. The water cooling the high-pressure electrodes is fed from an insulated tank 31 through pipe 35 in a manner similar to that for the low-pressure electrodes.  The tank is fed from a sprinkler 32 which is insulated from the high-pressure electrical circuit.  The used water passes through a flow control device 40 and discharges through a sprinkler 43 into the lower tank 44.  The upper tank 31 and the inlet and outlet pipes are insulated and connected to the high-pressure electrical circuit by the lead 50 to the transformer 2. Alternatively, the cooling water may be passed to the high- and low-pressure electrodes in series by a suitable modification of the connections to the electrodes.  In the outlet pipe 9 for the ozonized air, a gauging apparatus 72 is connected by pipes 71<1>, 71<2>, between which is a diaphragm 73 in which bears a plate 76 with a central aperture 77 which is accurately gauged to set up pressure variations between the pipes 71<1>, 71<2>.  The whole is mounted in a movable holder 70.  This arrangement may be replaced by venturi tubes.
