Abstract: ABSTRACT OF THE DISCLOSURE         A fault detector for an electrical transmission system and a remote current sensor for use therein.  The remote current sensor includes a Hall effect transducer for measuring the magnetic field surrounding a conductor of the transmission system to thereby monitor the current flowing through the conductor.  The transducer is positioned between a pair of tapered pole pieces for concentrating low density magnetic flux in the air into a high density magnetic flux focused onto the transducer.  The pole pieces enable the sensor to be positioned a distance from the conductor which is greater than the electrical arcing distance so as to allow use of the air gap between the conductor and sensor as insulation.  For a triangular configuration of conductors, two remote current sensors having orthogonal sensitive axes are positioned at a location equidistant from all three conductors.  A first sensor measures only the magnetic field surrounding a first conductor whereas the second sensor measures the vector sum of the magnetic fields surrounding the second and third conductors.  For a coplanar configuration of conductors, three remote current sensors are utilized.  Each sensor is positioned radially out-ward from its associated conductor, the sensitive axis of each sensor being tangent to the magnetic field surrounding its conductor.  The fault detector compares the highest positive sensor output and the least positive sensor output to respective set points enabling the detection of a fault within one quarter of a fault current cycle.  If either set point is exceeded, a relay is actuated to provide a fault indication signal.

Abstract: Abstract A  cowl-like  scrubber  (20)  for removing  dust generated by a longwall shearer has a housing (21) adapted to be mounted on the shearer near a cutter drum.  An air inlet (23) is provided in the housing to allow the dust-laden air to enter the scrubber (20).  Downstream from the inlet area is an arrangement of jet spray nozzles (30) which impart high velocity, small diameter water droplets.          The  water  droplets  entrain  the  dust particles  in the dust-laden air and move the resulting dust-laden mist to a mist eliminator (40) downstream from the jet spray nozzles where the dust-laden mist is then removed from the air.

Abstract: ELECTRIC HEATING APPLIANCE AND METHOD OF MAKING SAME         ABSTRACT OF THE DISCLOSURE        An electric heating appliance such as an electric comforter and a method of manufacturing the same in which two inner thermal insulation layers of resilient fiber fill material, one of which has substantially greater thermal conductivity than the other, and two outer textile fabric layers are stitched together along parallel spaced lines arranged in pairs of rows to form a shell with a series of laterally spaced channels in which are disposed an electric heating wire.  Each inner thermal insulation layer has facing means on its inner surface to facilitate insertion of the heating wire into the channels and to resist penetration of the heating wire into the layer.  Successive shells may be formed in a continuous manner by passing webs of the outer and inner layers in juxtaposed relationship through a multi-needle stitching machine which stitches the webs together with groups of spaced parallel rows of stitching.  The stitching of a central main area of the webs is intermittently interrupted to provide seriatim sets of rows of stitching separated at their respective ends by unstitched areas.           The stitched together webs are transversely cut along lines passing through the respective unstitched areas to provide successive shells each with the channels thereof open at their respective ends for subsequent insertion of the heating wire into the channels.

Abstract: ABSTRACT OF THE DISCLOSURE            A concrete wallform system comprises a vertical waler (formed of a pair of spaced channel beams bolted back to back) for stiffening the horizontal joists, which in turn back  the forming panels, and a tie rod extending between the channel beams, and a tie connector plate connecting the tie rod to the waler.  The connector plate is formed as a flat plate with an aperture approximately at the center and a hook portion along one edge thereof.  The hook portion overfits a lip on one wall of one of the channel beams.  A bolt clip near the other edge of the flat plate fastens the connector plate to a lip of a corresponding wall of the companion channel beam.  This bolt clip is standard hardware of the type used on aluminum joists (e.g., to join the waler to the joists).  A wing nut disposed at the aperture stresses the tie rod so that when wet cement is poured into the wallform, forces that are transmitted through the wallform to the waler are taken up by the tie rod.  Preferably, a raised spacer portion is provided on the back surface of the connector plate to aid in maintaining the spacing between the channel beams of the waler  and for locking the hook portion on its respective channel flange.

Abstract: ABSTRACT  OF THE DISCLOSURE         An electronic vernier measuring apparatus utilizes groups of stationary electrically conductive plates and a movable electrically conductive wide bar.  The wide bar is capacitively coupled to stationary commutator-like electri-cally conductive strips to provide a greatest capacitance when the wide movable bar is positioned juxtaposed with any one of the stationary electrically conductive plates and a portion of the stationary commutator element.  Individual plates of sub-pluralities of stationary plates are electri-cally interconnected to individual plates of adjacent sub-pluralities of stationary plates.  Each of the stationary plates is provided with a stripe-like portion directed towards its associated commutator-like conducting element.  An RC oscillator circuit is selectively coupled to each commutator-like element for a time period, during which each of the stationary plates in a sub-plurality is likewise coupled to the frequency determining input terminals of the oscillator circuit.  Frequency of the oscillator is monitored each time an individual stationary plate of a sub-plurality is connected into the oscillator circuit.  Vernier measurements are accom-plished by comparing the output frequency of the RC oscillator circuit during changes in capacitance, determined by the location of a plurality of vernier-like disposed narrow movable conducting bars, carried on the substrate.

Abstract: ABSTRACT      Apparatus for winding single-layer, precision wound dynamoelectric machine field coils and for insert-ing such coils in an internally-slotted core member includes a coil form having portions shaped to form a coil with two angled sections joined to end sections. The coil form has a distal end with a recess therein which communicates with the angled section-forming portions.  Insertion apparatus is provided having a cylindrical array of elongated, parallel blades defining gaps radially aligned with the centerline of the array.  The diameter of the wire from which the coil is wound approaches the width of the gaps. The array has a first position in which the distal ends of a group of adjacent blades extend into the coil form recess generally at right angles to the coil with the two gaps at the sides of the group exposed to the angled section-shaping portions so that a coil wound on the coil form may be transferred to the array with the angled sections extending through the two gaps and one end section disposed within the array. The array has a second position with the distal ends of the blades extending into the bore of the core and engaging teeth thereof, and with the two gaps communicating with two winding slots, the two gaps defining a first angle therebetween.  The angled section-shaping portions of the coil form define a second angle therebetween slightly smaller than the first angle and having a center spaced outwardly from the centerline of the array on the side thereof remote from the one end section in the first position of the array. The facing sides of each pair of adjacent blades which define the gaps diverge toward the center of the array 50 that the coil on the blades may be pivoted to an insertion position defining an acute angle with the blades with the two angled sections of the coil defining a third angle therebetween slightly larger than the first angle and the projected centerlines of the angled sections meeting at a point spaced in-wardly from the centerline of the array on the side thereof toward the one end section in the insertion position of the coil.
