Patent number: 6508981Abstract: A nodular or compacted graphite iron contains up to 6% aluminum, with high strength and good ductility over a wide temperature range, combined with excellent hot oxidation resistance and improved thermal fatigue resistance compared to ductile and SiMo ductile irons. The iron alloy of the invention contains, in addition to iron, from about 1 to about 6% aluminum, from about 2 to about 4.5% silicon, carbon in an amount where the weight percent carbon plus ⅓ the weight percent of silicon is up to about 5.2%, greater than or equal to about 0.02% cerium and up to about 1.5% molybdenum. All percentages are based on the total weight of the composition. The compositions may further contain up to about 7% nickel by weight.Type: GrantFiled: May 24, 2001Date of Patent: January 21, 2003Assignee: Wescast Industries, Inc.Inventors: A. Renaud Perrin, Gene B. Burger, Gangjun Liao

Patent number: 6152786Abstract: An electrical connector assembly having one-piece intermediate member (24, 24') and method of forming thereof are disclosed. In one embodiment, the one-piece intermediate member (24, 24') includes insulation-piercing serrations that provide for electrical conductivity between two electrical conductors. In another embodiment, the one-piece intermediate member (24, 24') provides for electrical conductivity between an insulated conductor and an uninsulated conductor. Intermediate member (24) includes movable sections (41) located inwardly from cable-engaging sections (40), with piercing serrations (46) extendable outward through slots (48) of the cable-engaging sections so as to penetrate the cables' insulation. In another embodiment, the electrical conductivity between the two electrical conductors is provided by a C-shaped receptacle element of the connector assembly. In all embodiments, the piercing serrations rigidly fix the electrical connection of the electrical conductors.Type: GrantFiled: April 23, 1999Date of Patent: November 28, 2000Assignee: The Whitaker CorporationInventors: Albert Renaud Perrin, Roland Sion Timsit

Patent number: 6146216Abstract: An electrical connector includes a C-shaped member (10) for use with a wedge. The C-shaped member includes a bight section (16) and two arcuate ears (18) extending from opposite sides of the bight section. The C-shaped member has an outer surface (24) with laterally extending ribs (22) and grooves (26) in an alternating sequence. The C-shaped member has an inner surface (34) that is initially formed with protrusions (36) each being opposed to one of the grooves. The protrusions compensate for bowing of the inner surface during forming of the arcuate ears, thereby resulting in the inner surface having a planar profile after forming.Type: GrantFiled: April 12, 1999Date of Patent: November 14, 2000Inventors: Roland Sion Timsit, Albert Renaud Perrin

Patent number: 6120334Abstract: The invention is directed to an electrical connector having a C-shaped member with two ears with arcuate inner surfaces. At least one of the arcuate inner surfaces has teeth extending inwardly with at least one of the teeth having a plastic cap disposed on it. A wedge is designed to be secured within the C-shaped member and terminated two cables therein. The wedge has two sides which cooperate with the arcuate inner surfaces to terminate the cables. At least one of the sides has a blade extending outwardly therefrom.Type: GrantFiled: April 9, 1999Date of Patent: September 19, 2000Inventors: Roland Sion Timsit, Albert Renaud Perrin
