Abstract:
A tailor weld blank assembly and method for making the blank assembly include providing a first metal sheet and a second metal sheet having at least one different characteristic from the first sheet. Complementary interlocking structures are provided on adjoining edges of the first and second sheets and the sheets are mechanically interlocked together by making a weld along the adjoining interlocked edges. Thereafter the permanently affixed together sheets are formed to make a formed sheet metal product. The provision of both a mechanical interlock and a weld provide a blank assembly that is strong for forming into a stamped product, and a metal product that is strong for its intended use.
Abstract:
A three-dimensional puzzle including a lenticular lens layer having a lens surface and a flat surface. A four color ink is applied to the flat surface and a layer of opaque ink is applied to the four color ink. A white paper backing is adhered to the layer of opaque ink using an emulsion based adhesive having a viscosity of approximately 1,600 mPas at 23° C., and a backer board comprised of four layers of cardboard is applied to the white paper backing. A method of manufacturing the three-dimensional puzzle is also disclosed.

Abstract:
A rotor assembly for an electric motor includes a plurality of laminations disposed in a stack, a tension rod extending axially through the rotor lamination stack, and end clamps disposed at each end of the rotor lamination stack and secured to the tension rod for compressing the stack to hold the laminations of the stack fixedly in position by compression. A method of stamping rotor and stator laminations for a doubly salient electric motor from a single piece of metal includes the steps of stamping a rotor lamination out of the piece of metal, and stamping the stator lamination out of the piece of metal offset from the stamping of the rotor lamination so that a tooth of the rotor lamination stamping is taken from the gap between two teeth of the stator lamination stamping. The centroids of the rotor and stator laminations in their stamped locations in the piece of metal are offset from one another.
Abstract:
A method of cutting blanks from an elastic paper comprises the following steps: removing a single elastic paper web of indefinite length from a mother roll; longitudinally cutting the single web, as it runs off the mother roll, into a plurality of paper panels; guiding the running paper panels in pairs into a superposed, face-to-face relationship to form at least one running superposed paper panel pair; guiding the running paper panel pair between cooperating cutting rollers of a rotary cutter and cutting the blanks from the running paper panel pair by the cutting rollers alternatingly from opposite sides of the paper panel pair while countersupporting the paper panel pair by the momentarily non-cutting cutting roller.
Abstract:
An automatic cable tie installation tool for applying discrete cable ties around bundles of wires or the like where the cable ties are provided to the tool on a continuous ribbon. The automatic tool including a dispenser mechanism that accepts the ribbon of cable ties and provides discrete cable ties therefrom; a tool mechanism that positions the discrete cable tie around the bundle of wire, tensions the tie to a preselected value and severs the tail of the cable tie; and a conveyance mechanism that delivers the cable tie provided by the dispenser mechansim to the tool mechanism. The dispenser mechanism including a reel mechanism for providing the cable tie ribbon to the dispenser mechanism, a grooved cylinder that carries individual cable ties for positioning and translating the ribbon longitudinally, an index mechanism for rotating the cylinder in accurate increments, a mechanism for separating individual cable ties from the ribbon, a guide mechanism for positioning the ribbon laterally relative to the separation means and a mechanism for transferring the separated cable ties to the conveyance mechanism. The ribbon includes a strip portion extending the length of the ribbon having a plurality of cable ties connected thereto by respective connecting tabs. The strip portion having an alignment mechanism adapted to cooperate with the guide mechanism in the dispenser to accurately position the ribbon laterally in the dispenser mechanism.
Abstract:
An automatic buffing machine and method for automatically buffing a golf ball are disclosed. The golf ball is oriented such that the flash ring is in a predetermined plane and then the flash ring is removed. The golf ball matrix is preferably utilized to orient the golf ball and both cutting and sanding are preferably used to remove the flash ring.
Abstract:
Tool guide for a knife-edged hand tool for use in the fabrication of an air duct transition from a sheet of fibrous material, said sheet having transversely extending folding grooves therein, for cutting from said panel a wedge-shaped piece of material of predetermined size.
Abstract:
One disclosed method involves punching winding leg and yoke laminations from a strip, subsequently forming a core yoke section, and forming a core winding leg (or coil core). Thereafter, an excitation coil is supported on the coil core, and the coil core and core yoke are assembled in reoriented relation relative to the relative orientation of the laminations when punched from the original strip. The winding leg laminations are reoriented 180 degrees, about a longitudinally extending axis, so that a first surface of the original strip material which faces one direction, as it is punched from the strip, faces an opposite direction in the winding leg section in a finished motor.The geometrical configuration of the laminations prevent a random location of the winding legs relative to the yoke laminations, yet permits two distinctly different relative lamination orientations. A longitudinal reference line along the winding leg is identified, and keying or interlocking means symmetrical about the reference line are provided, but the winding accommodating portion of the winding leg is asymmetrical about the same reference line. Therefore, two distinct winding window openings may be provided, depending on the orientation of the winding leg.
