Abstract: 1,265,313. Loom stop motions. NORTHROP WEAVING MACHINERY Ltd. 3 March, 1969 [2 March, 1968], No. 10273/68. Heading D1E. [Also in Division H3] A loom stop motion comprises means for comparing pulses indicating the time at which the shuttle passes a point on the sley with timing pulses generated, e.g. by means rotating with the loom crank shaft. Under normal conditions shuttle pulses and crankshaft pulses follow one another alternately, but if two like pulses succeed one another, the comparator immediately de-energizes a solenoid to operate the stop motion gear. The shuttle pulses are produced by passage of a magnet (26), Fig. 1 (not shown) in the shuttle past a pick-up (28) at the centre of the sley and the crankshaft pulses are produced by passage of a magnet (34), Fig. 2 (not shown) on a wheel (30) on the crankshaft past a pick-up (36) on the loom frame. The pulses are fed to a bistable electronic device A, Fig. 4 and comparators B, C, the device A being arranged so that it is set by a shuttle pulse and reset by a crankshaft pulse. The comparators B, C, compare the outputs of system A with the incoming pulses. If the correct alteration of signals is received no output appears at either comparator. If, however, two crankshaft pulses or two shuttle pulses succeed one another, system A is switched over and an output appears at comparator B or C respectively which is amplified at D and E and deenergises relay F to stop the loom. The stop rotor gear comprises brake and clutch discs 114, 112, Fig. 10 keyed to the loom shaft 108 and actuated by a slide block 128 connected to link 184 operated from a hand lever 130. To start the loom lever 130 is moved to the left, Fig. 6, and a stop thereon moves freely pivoted lever 134 anticlockwise to a dead centre position (152), Fig. 9 (not shown). Rod 142 rotates lever 146 clockwise to move catch member 156, Fig. 7, held in the engaging position by energisation of solenoid 162, downwards, a shoulder on which engages shoulder 180 to rotate lever 186 clockwise to a dead centre position in which spring 188 is compressed, an arm 182 of lever 186 simultaneously moving link 184 to engage clutch 144 will drive pulley 106 to start the loom. Lever 130 is returned to its original position by a spring and the parts 142, 146, 156, 186 and 184 remain held in their operative position due to the dead centre position of lever 134. If a "stop" condition is indicated by the comparator, solenoid 162 is de-energised to move catch 156 to left to release lever 186, whereupon spring 188 rapidly moves the linkage to the stop position in which member 184 disengages clutch 114 and engages brake 112 to stop the loom.

The further conductor consists either of a single copper or titanium solid wire, a plurality of thinner wires with their axes parallel to one another, or a copper clad aluminium wire. The copper cladding is provided by either winding copper strips helically around the aluminium conductor, dipping the aluminium conductor into a copper chloride melt, or by vapour coating the aluminium with copper. The copper cladding is specially treated by mechanical roughening or artificial oxidation, and covered with a corrosion-inhibiting, highly heat-resistant, adhesive composition or lacquer layer. The conductivity of the neutral conductor is made similar to that of each phase conductor by reducing the cross-section of the associated aluminium conductor by means of longitudinal grooves or holes or by the removal of aluminium from the apices of the conductor. Additional insulant is employed to replace the aluminium removed and to fill the interstices between additional aluminium wires which may be stranded around the neutral conductor. The additional conductor 5, if stranded, may be given additional extra protection by filling its interstices with an adhesive corrosion-inhibiting composition based on high molecular weight polybutenes, polyurethanes, chloroprenes and copolymers of ethylene and vinyl acetate or silicones which are cross-linked and of low thermal conductivity. The additional conductor 5 may be external to the aluminium neutral conductor, being either of angular cross-section pressed against the inner apex, or of the same cross-section as part of the aluminium removed from the apex or of circular cross-section pressed against a plane surface produced by such removal.

As shown, the plate 10, with load (not shown), has been lifted by inflating the set 1. The set 2 is now inflated, the reaction between the sets 1, 2 causing the plate 10 to move slightly to the right, Fig. 1b (not shown). The set 1 is next deflated, the set 2 taking over the full load and assuming a symmetrical shape, the plate 10 moving again slightly to the right. Set 3 is next inflated followed by deflation of set 2, causing further movement to the right. The whole cycle is then repeated.  Similar sets of parallel inflatable bags may be attached to either side of a base-plate, Fig. 9 (not shown), in which case the device may insert itself under a load or remove itself from underneath a load by simultaneous operation of both sets. Such a device may transport a load (after inserting itself underneath it) by interrupting the operation of the upper bags. At the destination operating the upper bags and interrupting the operation of the lower bags may be used to discharge the load. In a modification of this arrangement the two layers extend at rightangles to provide movement in two directions. In a further embodiment, Fig. 12 (not shown), the device comprises a multiplicity of pockets arranged in an orthogonal matrix. The pockets may be inflated individually to provide movement in either of the two perpendicular directions in which the rows of pockets extend. A load can thus be guided in confined spaces and around bends.  Non-planar conveyer mats may be provided to suit particular applications such as conveying barrels or boat hulls. If of annular construction the bags may enter and possibly plug a pipe or convey articles through a pipe, or a pipe may be moved along an internal supoorting bar.
