Patent number: 4062161Abstract: The head portion of a T-shape strip of elastomeric material is threaded lengthwise into the undercut sides of a channel formed in one of two members to be joined together so that the stem or body portion of the strip projects therefrom. The strip is so located, and this projecting stem portion is of such thickness, as to enter a narrow channel with serrated sides formed in the other of said members. Supported as on a fulcrum on a narrow neck portion projecting from the free edge of the strip stem portion, and spaced slightly from the stem portion, is a transversely curved portion which is slightly wider than the serrated channel. Upon movement of the two members toward each other, the stem portion forces the transversely curved portion to flex, and enter into the serrated channel, in which position the edges of the curved portion are in gripping relation with the channel serrations, and thus resist its withdrawal.Type: GrantFiled: April 5, 1976Date of Patent: December 13, 1977Assignee: Rohr Industries, Inc.Inventor: Theodor C.

Patent number: 4054481Abstract: For assemblying a plurality of extruded aluminum strakes with their edges formed for interconnection by plastic key joints, thereby to form a side wall for a transit vehicle, a panel support is formed to support a required plurality of the strakes in completed conformation. Clamping mechanism then squeezes the strakes laterally to a designed assembled width, thereby interlocking the joints, and opening up a key-forming passage lengthwise within each joint. An adhesive injecting manifold is mounted for reciprocation toward and away from one end of a panel on the support, with a nozzle on each of a plurality of outlets of the manifold for sealed engagement, one with each panel joint passage. The manifold inlet has controlled connection to a supply of pressurized, flowable, hardenable, key-forming compound for injection into the joint passages, with flushing means arranged for alternate connection to the nozzles for flushing out the nozzles and manifold after use.Type: GrantFiled: April 21, 1976Date of Patent: October 18, 1977Assignee: Rohr Industries, Inc.Inventor: George Heffner

Patent number: 4033033Abstract: A plurality of sub-assemblies comprising elements of a transit vehicle are first completed individually in their respective jigs. Each of selected ones of these sub-assemblies has embodied therein an extrusion having a trackway formed thereon for alignment with a selected conveyor way provided therefor in a collector, which travels in successive cycles along a selected path on a final assembly floor. Each of said selected sub-assemblies has joint means formed thereon for interlocking engagement with complementary joint means provided on one or more of the other sub-assemblies. The selected sub-assemblies are conveyed, by means of their trackways riding along their respective conveyor ways, into the collector, and thus into interlocked relation with each other in positions of final assembly therein, where they are secured permanently in such interlocked relation. Other sub-assemblies are then added to produce a complete transit vehicle.Type: GrantFiled: February 23, 1976Date of Patent: July 5, 1977Assignee: Rohr Industries, Inc.Inventor: George R. Heffner

Patent number: 4029479Abstract: For the diffusion bonding of members of titanium and some titanium alloys, layers of Cu, Ag and Ni are deposited by plating on both sides of a sheet of etched, chemically clean, titanium or titanium alloy foil of a thickness preferably less than 0.001 inch. The plated foil is interposed between faying surfaces of the members to be bonded together, and the members, with the interposed foil, are sealed under pressure, in an inert atmosphere and under partial vacuum or hard vacuum of, for example, 10.sup..sup.-4 Torr. The parts thus prepared are heated to brazing temperature to render liquidus plating material and thereby establish a diffusion bridge between each plated face of the foil and the adjacent faying surface of each of the members. Heating is continued to induce atomic diffusion in the zone thus established between the titanium of the foil and the members, and between the members themselves, until the diffusion zone becomes principally titanium with traces of plating materials diffused throughout.Type: GrantFiled: June 1, 1976Date of Patent: June 14, 1977Assignee: Rohr Industries, Inc.Inventor: Elmo G. Parker
