  • Patent number: 7117707
    Abstract: A method of thermomechanically forming an aluminide part of a workpiece resistively heats at least a portion of the aluminide part, plastically deforms the heated portion of the aluminide part to a predetermined shape by applying pressure to the aluminide part positioned in a shaping member, and cools the aluminide part while applying pressure to maintain the aluminide part in the predetermined shape. The shaping member is movable mounted on a support base and a source of electricity provides an electrical current passing through the aluminide part for resistive heating of the part. The aluminide part can be a heater blade array for an electrically heated cigarette smoking system.

  • Patent number: 5962159
    Abstract: The battery pack which can be attached independent of its orientation houses rechargeable batteries within a case and has positive and negative (+ -) charge-discharge terminals at one end of the case. The charge-discharge terminals are arranged to connect to electrical apparatus without regard to the orientation of the front or back sides of the case. The + - charge-discharge terminals are sheet metal bent in flat-sided c-shapes, and comprise a parallel charge-discharge terminal piece which attaches to the case parallel to the case opening plane and a perpendicular charge-discharge terminal piece which attaches to the case perpendicular to the parallel charge-discharge terminal piece. The parallel charge-discharge terminal piece attaches by fitting into an attachment section formed as a single piece in the case opening.
