    Abstract: An A.C. alternator includes laminated stator core with an tubular frame formed from a plate member which is wrapped tightly about the core and with the opposed end edges of the frame plate welded to the core. The stator laminations having a square perimeter with the corners rounded with a radius of the final core diameter. The corner portion are further provided with a control welding notch and a plurality of circumferentially distributed openings. The laminations are stacked in rotated relation to form the core with a true constant diameter. Each lamination is rotated in the same direction of rotation for 120 degrees relative to the adjacent laminations. The multiple openings in the corner portions are constructed and arranged such that the rotating laminations aligned the similar openings and define a plurality of unobstructed axial cooling passages. The laminations are rotated to establish skewed elongated slots, central notches and air flow openings.

  • Patent number: 4406063
    Abstract: A pinking shears having a pair of blades pivotally connected together by a bolt and having cooperative teeth formed along their leading edges and having handles at the ends of the blades opposite said teeth. A non-metallic spacer and pressure producing ridge member is located between the blades and has an apertured spacer portion through which the bolt extends and which serves to provide rough blade separation. The member also has a pressure producing ridge located at the handle side of said bolt and for bearing against the blades to produce cutting pressure between the teeth of the blades. The blades have tapered leads which cooperate with one another as the shears are closed to provide gradual smooth engagement of the blades.
