Patent number: 6514063Abstract: The present invention relates to a method and tooling for forming a stent and the stent so formed. The stent includes filaments of a first material and joints of a second material. The present invention also discloses the above described stent in combination with an angioplasty balloon. The tooling in accordance with the present invention provides a fixture having grooves that receive the filaments of the stent to hold the filaments in place for joining. The joining of all of the filaments can be performed simultaneously by laser welding or injection molding a joint material. The tooling in accordance with the present invention also provides the capability to mold the stent as one piece. The method in accordance with the present invention includes the steps of providing a fixture with internal grooves, placing filaments into the grooves and joining the filaments together.Type: GrantFiled: February 26, 2001Date of Patent: February 4, 2003Assignee: International Business Machines CorporationInventors: Michael A. Acciai, Richard R. Hall, John T. Legg

Publication number: 20020074089Abstract: An apparatus for providing a uniform web of filaments comprises tube filament transport means exiting through a confined zone of reduced turbulence, which preferably comprises a delivery slot. The delivery slot is configured with sidewalls substantially parallel to one another and to the transport tubes, so that filaments undergo minimal machine direction deflection in the slot. Charging means within the slot charge the filaments for further cross direction separation. A method of providing a uniform web of filaments comprises transporting filaments through transport tubes, through a tapered transition member, and into a delivery slot. The delivery slot is defined by sidewalls that are substantially parallel to one another and to the transport tubes, so that minimal machine direction deflection of the filaments occurs. The filaments are also charged by electrostatic charging means while they are in the slot for further separation.Type: ApplicationFiled: February 7, 2002Publication date: June 20, 2002Inventors: Richard Ferencz, Jian Weng, Brian Yamanouchi

Patent number: 6277238Abstract: The method for the manufacture of sections of fiber-plastic compound materials is carried out by means of at least one draw nozzle (10). In this nozzle, fibers (41) which are impregnated with flowable plastic (42) are formed under pressure to a product (41) with a predetermined cross-section and consolidated with the withdrawal of heat. The cross-sectional surface of the draw nozzle is periodically increased and decreased in time in its entire shape imparting region, with a value for the frequency of the oscillating cross-sectional surface being chosen less that 1 kHz, preferably less than 100 Hz.Type: GrantFiled: August 3, 1999Date of Patent: August 21, 2001Assignee: Sulzer Innotec AGInventors: Albert Maria Vodermayer, Jens Kärger, Hans Erlach

Patent number: 6230775Abstract: In the embodiment described in the specification, a high temperature wet filament winding arrangement has a wet bath containing a resin at a temperature above 500° F. and filaments drawn from a spool rack are passed through the wet bath and then through a heated comb which maintains the temperature of the filaments above 500° F., after which the filaments are passed through a heated passage controlled to maintain the temperature above 500° F. A winding eye, also heated to maintain the filament temperature above 500° F., directs the heated fibers onto a mandrel where they are wound in uniform layers into the form of a final product. A mandrel heater heats the mandrel to which the fibers are being applied so as to maintain a uniform temperature above 500° F.Type: GrantFiled: January 21, 1999Date of Patent: May 15, 2001Assignee: Electric Boat CorporationInventors: Mitchell D.
