  • Patent number: 6643004
    Abstract: Field-deployable spatial positioning or measurement systems are provided for improved versatility, reliability and performance. The spatial positioning or measurement systems use rotating laser fans or beams for positioning and measuring and include a system integrated field-deployable length standard that uses a reelable tape with positional indents. The systems further include the use of labyrinth seals at interface volumes between rotating laser heads and transmitter assemblies to prevent ingress of contaminants and allow for elimination of the use of rotary seals. Further, new dynamic leveling techniques are provided to plumb positional laser transmitter systems. Still further, strobe beam configurations are provided for improved near/far performance and a vertical mode sensing scheme that allows switching to measuring tall structures when needed.

  • Patent number: 5379511
    Abstract: Pivotally mounted wire trimming blades having sharp, wire trimming, edges are positioned so that they extend through notches in the inner commutator shield of a double flier armature winder and lie against commutator start tangs and extend closely adjacent the outer periphery of the inner shield. The start or finish wires, as the case may be, are severed by being pulled against the wire trimming edges. The wire trimming edges have offset portions, or else the trimming blades are movable to offset locations, so that the trimming of the start wires are at locations which are radially and longitudinally offset from the locations at which the finish wires are trimmed.
