Abstract: Abstract A system for monitoring the capacitor batteries of a three-phase filter circuit.  Each capacitor battery is formed of a plurality of parallel legs each having a plurality of sectional capacitors which are connected in series with fuses.  Adjacent ones of the sectional capacitors are coupled to one another.  In a three-phase system, three capacitor batteries are coupled to one another in a Y-circuit configuration, the Y-circuit node being coupled to a reference potential, illustratively ground.  The magnitude and phase of the fundamental frequency component of the current flowing from the Y-circuit node to the reference potential is monitored, variations therein being evaluated to identify defective sectional capacitors.  Only variations in the Y-circuit node current which occur rapidly will trigger fault signals, thereby preventing false indications resulting from variations in temperature.

Abstract: ABSTRACT      A method of applying a layer of resin and axial fibres to a workpiece such as an automotive propeller shaft during the manufacture of the shaft includes the steps of arranging a series of fibre feed stations around the periphery of the workpiece,  causing  the  fibres  from the feed  stations  to converge along a conical path with the workpiece where they are united with the workpiece by circumferentially wrapped fibres.  Resin is applied to the cone of fibres by throwing it out under centrifugal force from a rotating annular groove when the fibres are sufficiently close together to support a layer of resin between adjacent fibres.  As the fibres are then pulled on to the workpiece, good impregnation of the resin into the fibres is achieved.

Abstract: TRACK RECOIL SYSTEM                 Abstract of the Disclosure A track recoil system includes a track adjuster actuator which may be extended by the introduction of grease to compress a previously installed coil compression spring to establish a pre-selected preload in the latter.  The track adjuster includes a housing having a cylinder telescopically mounted therein with the housing bearing directly on the spring and with the cylinder having a head engaged with a removable adjuster stop when the adjuster is being extended for compressing the spring.  Preload spacers hold the housing in place to in turn hold the spring in a desired preloaded state so as to permit grease to be bled from the actuator to allow the adjuster to be collapsed by backing the cylinder head away from the adjuster stop so as to leave clear-ance between the adjuster for permitting the adjuster to be later extended, if necessary, to accommodate for an increase in track length due to wear.  Compression of the spring may be accomplished by removing the adjuster stop and inserting a suitable jack between a track frame member, to which the stop is releasably secured, and the adjuster.

Abstract: WIDE-SWEEP CARPET CLEANER BRISTLE STRIP AND BRUSH ROLL             ABSTRACT      A brush or agitator roll of a suction cleaner for carpets or other floor coverings is provided with a plur-ality, for example, a pair of diametrically opposed longi-tudinally extending spiral grooves and a bristle/agitator strip is spirally, slidably engaged in each spiral groove. Each strip has a section including a band forming part of a crowned pulley for a drive belt.  On either side thereof a series of holes is provided for receiving bristle tufts. On each side, the strip is provided with a radial hole at a medial location with each succeeding bristle hole being elongated so that its inner wall is radial and the outer wall is inclined away from the center by an amount equal to the inclination of the adjacent hole plus a fixed incre-mental amount.  Thus, although the inner edge of each hole is generally upright or radial, the outside edges are suc-cessively angled outwardly so that the holes can be molded utilizing a single core strip and the bristle tufts can be inserted and stapled radially and yet will have substantial bristles angled outwardly so as to provide a brush having a line of bristles effectively longer than the supporting strip.  Grooves are also provided on the back and two sides of the strip to increase its flexibility, enabling it to be slid into the groove on the roll without the necessitating pre-heating of the strip to soften it.

Abstract: Abstract The invention relates to a cutting roller for a mining machine, especially for coal mining.  Its object is to facilitate smoother delivery by such cutting rollers, without increasing the number of vanes (4 and 5) extend-ing helically about the main body and tipped with cutters.  This is achieved by means of helical guides (12 and 13) primarily without cutters and disposed only towards the discharge end of the cutting roller.  By way of comparison, the guides extend over a short axial portion of the cutting roller, are disposed between the vanes (4,5) and run parallel thereto, i.e. are arranged at the same helix angle as the vanes (4,5).  The number of guides (12 and 13) corresponds to the number of vanes (4,5).  The guides (12 and 13) start at the end facing the end ring 3 at about the height of the outer side of the tubular main body and gradually increase to their maximum outer diameter so that the flow of the mineral mined, which are conveyed between the vanes (4,5) are gradually and com-pletely divided into additional flows shortly before their discharge, whereby a smoother delivery with a smaller proportion of fine material is obtained.
