IPC: B61B12/12
Filed: 1921-01-18
Abstract: 183,159. Roe, L. J. (Executrix of Roe J. P.), and Ropeways, Ltd. Jan. 18, 1921. Rope grips.-Comprises a load-actuated grip for single-cable aerial ropeways in which gripping levers f, g pivotally connected at h are operated by an antifriction roller o on the carrier frame, so that vertical movement of the carrier relatively to the supporting ,and hauling rope e causes the jaws to gnip the rope, while when the carrier is supported by a shunt rail or rope d the jaws are opened positively by means which serve also to retain the jaw levers in the carrier. In the form shown in Figs. 1 and 3, the levers are formed with surfaces f<3>, f<4> acted upon by the roller o, and are guided in a box a<1> of the carrier by lugs f<7>, g<7>. The release of the rope is effected by means of stops m, n in the box acting on surfaces f<5> of the levers. The, stop n is removable so that the jaws may be inserted. In the form shown in Fig. 12 the roller o is below the pivot h and the levers are crossed. The jaws are opened and the levers retained in the box bv extensions. at the top ends of the levers engaging the edges of the box. Modifications are described in which (1) the stops m, n, Fig. 3, are replaced by adjustable screws; (2) the jaws are opened to release the rope, by means of a spring connecting the top ends of the levers, these ends being so curved or recessed that when brought together by the spring they enclose the roller o and support the jaws, and (3) two rollers o are employed, one acting on each lever. Adjustment for wear and for various ropes may be effected by using rollers o of different sizes. The grip may be mounted in a separate box pivoted to the carrier box a<1> about a horizontal pivot transverse to the rope. The carrier a, Fig. 1, may be provided with a grip at one end and a support s at the other, as shown, or may have a grip at each end.

Title: Method of operating a plasma arc torch
IPC: B23K10/00
Filed: 1974-01-19
Abstract: 1462682 Plasma arc welding and cutting PRODUCTION ENG RESEARCH ASSOCIATION 19 Jan 1974 02611/74 Headings B3R and B3V In a method of operating a plasma torch, e.g. for fusion welding, cutting or piercing, a first electric power supply 4 is connected between the electrode 2 and nozzle 1 and ionizes a stream of gas, e.g. argon passing through the nozzle from inlet 3 to create a pilot plasma arc which issues as a plasma jet from the nozzle. A second power supply 5, embodying an energy storage system, such as a capacitor or bank of capacitors, is connected between the torch nozzle 1 or, as shown, electrode 2 and a workpiece W and the energy storage system is discharged into the plasma arc in at least one controlled discrete pulse to produce a main arc discharge or a series of discharges between the torch and the workpiece. The pilot arc may be continuous or non- continuous, i.e. it may be in the form of a series of discrete arcs and produced by a similar energy storage system as that in power supply 5. The main arc may be initiated by the pilot arc plasma jet contacting the workpiece to complete the main arc circuit. The energy storage system or systems may be repeatedly charged and discharged by suitable means. The duration and shape of the discrete pulses created by the energy storage system in supply 5 may be adjusted. The form of the main arc discharge plasma is said not to be appreciably affected by moving the negative of the power supply 5 from the electrode 2 to the nozzle 1. Shielding gas may also be applied around the main plasma arc.

Title: Improvements in or relating to electro-magnetic brakes
Inventor: BARNETT KENNETH EDWARD
IPC: F16D59/02
Filed: 1961-01-25
Abstract: 989,631. Electromagnetic disc brakes; securing discs on shafts. BROOKHIRST IGRANIC Ltd. Jan. 25, 1962 [Jan. 25, 1961], No. 2915/61. Headings F2E and F2U. A spring-applied, electromagnetically released, disc brake is provided with alternative hand-operated release means in the form of a cam device rotatable about an axis at right angles to the axis of the brake and engageable with tappets carried by one of the outer discs to move it outwards against spring pressure. In one embodiment, Figs. 1, 3 and 4, an outer disc 3 is urged by springs 2 towards a fixed disc 1 to grip between the discs a rotating disc 5 having segmental linings 6. The disc 5 is slotted at 26 to prevent vibration and is provided with an aperture 24 for sliding engagement with a rectangular-section portion of the shaft to be braked (not shown), an anti-rattle spring 27 being secured to the disc 5 so that it extends around a recess 28 to grip the shaft. The springs 2 are adjustable by nuts 15 and react against springs 4 which maintain the disc 3 in contact with a plate 7 in which springs 2 are seated. Plate 7 carries magnet armature 10 and also tappets 8 and 34, the former adjustable to vary the spacing between plates 3 and 7, and the latter being adjustable to vary the clearance between their inner ends and flats on a pair of cam-shafts 32 located on opposite sides of the disc assembly. Each shaft 32 is journalled in a plate 30 secured to disc 1 and carries a hand lever 33 which is loaded by gravity or by a spring to the full-line position. On the levers being moved to the position 33a the cylindrical faces of the shafts 32 engage the tappets 34 to force the plate 7 outwardly to release the brake. Electromagnetic release of the brake is effected by energizing coils 14 to a magnet stator assembly 11 carried by a back plate 12. Should the brake have already been released manually the energization of the magnet moves the plate 7 slightly further so that levers 33 return to their inoperative positions by gravity or spring action. When the brake is applied by deenergizing the electromagnet a gap exists between the tappets 34 and the flats of the shafts 32. This gap is reduced by wear resulting in a corresponding increase in the electromagnetic gap. The arrangement is such that before the latter gap has increased to a dangerous extent braking is impaired by the engagement of the tappets 34 with the flats on shafts 32, so that an indication is given of the need for adjustment. In a second embodiment, Fig. 6, the brake is similar to that described above excepting that an additional rotating disc 40 and an additional stationary disc 41 are provided. The cam-shafts still act on the plate 7 via elongated tappets 34a, but tappets 8 are replaced by assemblies 42, 43, 44 which pro. vide not only for adjustment between the discs 3 and 7, but also for adjustment of an abutment 45 which limits separation of discs 7 and 41.
