  • Patent number: 7686386
    Abstract: An automotive body and trim assembly is provided that utilizes locating features on only a single sheet metal layer of a multi-layer body frame pillar to position a trim member, thus minimizing variability in the final assembled position of the trim member. The single sheet metal layer has both a fore-aft-locating feature and a cross-car-locating feature. A fore-aft-positioning feature and a cross-car-positioning feature on the pillar trim member are spaced to permit contact with the fore-aft-locating feature and the cross-car-locating feature, respectively when the pillar trim member is assembled with the body frame pillar, so that only the single sheet metal layer determines the fore-aft and cross-car position of the pillar trim member. A method of assembling a pillar trim member and a body frame pillar having multiple sheet metal layers is also provided.

  • Patent number: 4745675
    Abstract: A method of manufacturing a stator lamination for a dynamoelectric machine. A length of steel wire is formed into alternate straight and undulated portions and is formed into a coil such that the inner turn of the coil coprresponds to the undulated portion and the outer turn corresponds to the straight portion of the wire. The coil of wire is placed in a die cavity of a die that has a configuration corresponding to a stator lamination. The loops of the undulated portion are placed in radially extending grooves of the die cavity and the outer turns of the coil are placed in an annular groove of the die cavity. The die and a punch are utilized to coin the wire to the shape of the die cavity.

  • Patent number: 4399379
    Abstract: A fan assembly has a sealing ring which rotatably fits with a similar feature on a machine casting when the fan is assembled to the machine to provide a labyrinth type seal which is maintained over a wide variation and axial gap to inhibit the flow of air bypassing the normal flow through the machine so that the fan pumps greater quantities of air through the machine for improved cooling of all elements therein.

  • Patent number: 4082926
    Abstract: To reduce the potential magnitude necessary to break down the arc gap between an ignition distributor rotor segment output tip and each of the output electrodes of an associated distributor cap, a pair of electrical conductor members in electrical contact with the rotor body and segment at an area radially inwardly from the output tip of the segment are provided. These conductor members extend radially outwardly toward the rotor segment output tip in a manner to define a pair of circumferentially displaced terminating points in bracketing relationship with the output tip.
