The receiving member is a double-walled blow-molded thermoplastic component having an outer wall, an inner wall, and an open-ended receptacle. The open ended receptacle is defined by an arcuate pocket positioned opposite the open end, a stationary wall extending from the pocket and facing generally in a first direction, and a deflecting wall positioned opposite the stationary wall and facing generally in a second direction opposite the first direction. The pinned member includes a cylindrical pin. The method comprises as a first step passing the cylindrical pin through the open end of the receptacle and into contact with the pocket.Type: GrantFiled: November 27, 2000Date of Patent: May 7, 2002Assignee: Delta Consolidated IndustriesInventor: J. Parks Newby, Sr.

Patent number: 6381820Abstract: A semiconductor bulk acoustic resonator (SBAR) with improved passband insertion loss and phase performance characteristics making it suitable for use in a wider variety of narrowband filtering applications. The SBAR is configured to suppress lateral propagating acoustical wave mode. The lateral acoustical wave modes are controlled by varying the lateral dimension of the resonator electrodes and or utilizing a viscous acoustic damping material, such as a viscoelastic material, such as polyimide, along at least~a portion of the perimeter of the electrodes to attenuate reflections of the lateral acoustic modes at the electrode edges back into the electrode region.Type: GrantFiled: September 28, 1999Date of Patent: May 7, 2002Assignee: TRW Inc.Inventors: Drew Cushman, Jay D. Crawford

Patent number: 6381821Abstract: Emitter barb installation tool 20 has driving mechanism 24, emitter barb feeder magazine 26 and pipe support 22. Pipe support 22 holds and supports a pipe 5. Feeder magazine 26 holds and feeds emitter barbs 10. Feeder magazine 26 places one of the emitter barbs 10 into a driving position. Driving mechanism 24 drives the emitter barb 10 from the driving position towards and into the pipe 5 held and supported by the pipe support 22. After the one barb 10 has been driven into the pipe 5, the pipe 5 with installed barb 10 is released from the tool 20. Another emitter barb 10 in the feeder magazine 26 is then automatically located into the driving position for the next installation into a pipe 5. This installation process automatically and continuously repeats for insertion of additional emitter barbs 10. Individual emitter barbs 10 are detachably coupled to one another to form an emitter barb cluster 74.Type: GrantFiled: November 24, 1999Date of Patent: May 7, 2002Assignee: L.A.P. Innovations, Inc.Inventor: Larry A. Panyon, Jr.

Patent number: 6381823Abstract: A method of forming a gas tank includes forming two halves and welding the halves together. Two types of welds are used, tack welds for holding the complete welds after different steps have been taken to the tack weld elements or parts, and stitch welds to complete the welding of the two halves. Reinforcement is added where necessary. Double tanks, for both gasoline and oil, are also fabricated of essentially the same method steps.Type: GrantFiled: January 31, 2000Date of Patent: May 7, 2002Inventor: Kyle P. Krejci

Patent number: 6381825Abstract: A method for stacking fibers less than 10 mm long into a cartridge case, including an impregnation stage for fibers arrayed into at least one skein together with a solidifiable material, the skein being solidifiable inside a mold and then, in the solidified state, being cut into at least two slices each of a thickness which is the desired fiber length. Such cartridges are for use as screens or decoys against radar or other detection or guidance systems.Type: GrantFiled: July 27, 2000Date of Patent: May 7, 2002Assignee: Giat IndustriesInventors: Muriel Regis, Martial Bernard, André Espagnacq

Patent number: 6381826Abstract: The process for making fine metallic mesh is disclosed comprising the steps of cladding an array of metallic wires with an array cladding material to provide an array cladding. The array cladding is drawn for reducing the diameter thereof and for reducing the corresponding diameters of each of the metallic wires for producing a clad array of fine metallic fibers within the array cladding. The array cladding is fashioned into a mesh by weaving, braiding, crocheting and the like thereby forming a series of bends in the clad array for reducing interaction between adjacent portions of the array cladding. The array cladding material is removed for producing fine metallic mesh from the array of the fine metallic fibers.Type: GrantFiled: September 10, 2001Date of Patent: May 7, 2002Assignee: USF Filtration & Separations Group, Inc.Inventors: Nathaniel R. Quick, Michael Liberman

Patent number: 6381827Abstract: A high temperature bolting system for clamping steam turbine housings and similar high temperature parts together while operating at a temperature of 800° F. to 1200° F. An elongated fastener shank and housing material have similar coefficient of thermal expansion. The shank has a tensile strength several times greater than the housing to maintain a clamping force during thermal excursions. The diameter of the shank is reduced due to the large creep strength difference between the elongated fastener shank and the clamped parts. The reduced shank diameter allows an increased in the clamping load by providing an increased surface area in the clamped part. A stress generating flange is provided with jackbolts to establish the clamping load at room temperature. A threaded sleeve is interposed between the threads at the end of the shank and the threads of the housing so that the housing threads have a sufficiently large area for withstanding the clamping load.Type: GrantFiled: September 15, 2000Date of Patent: May 7, 2002Assignee: Steinbock Machinery Co.Inventor: Rolf H.

Patent number: 6381828Abstract: A method for chemically etching a forged striking plate for a golf club to uniformly remove 0.002 inch to 0.015 inch of material therefrom. The forged striking plate is placed in an acidic bath to uniformly remove material from all surfaces of the striking plate. The forging process, conducted prior to etching, involves multiple heating and pressing of a metal bar to obtain a final face member configuration. The heating of the metal bar is performed at temperatures below 1000° C. for less than twenty minutes. The final face member configuration has a striking plate with regions of variable thickness. The metal bar is preferably composed of a forged titanium material.Type: GrantFiled: April 13, 2000Date of Patent: May 7, 2002Assignee: Callaway Golf CompanyInventors: Ronald C. Boyce, Richard C. Helmstetter, Alan Hocknell, J. Andrew Galloway
