Patent number: 6217809Abstract: A method for splicing an improved strength tape having longitudinally extended strands comprises the trimming or patterning of the strands of the respective ends that are to be joined so that the ends can be mated together in a meshing arrangement. The two ends are placed in a splicing tray. An adhesive film is interposed between the two ends and the splice tray is closed. The splice tray is placed in a compression molding press which applies a predetermined time-temperature-pressure treatment profile which cures the adhesive film. The resulting splice has essentially the same physical dimensions of the strength tape, and similar stiffness characteristics to that of the strength tape. Further, the strength of the splice is more than sufficient for use in a communication cable. Because the complete splice process can be completed in less than 4 to 5 minutes, the splice can be performed on-line with the use of a strength tape accumulator.Type: GrantFiled: September 29, 1998Date of Patent: April 17, 2001Assignee: Lucent Technologies, Inc.Inventors: Raymond P.

Patent number: 5911938Abstract: A molded unit is made using a rotational molding process. In making the molded unit, a tool assembly houses the mold material. A fixture assembly is also contained within the tool assembly. The fixture assembly holds an insert member in place. The insert member becomes an integral part of the molded unit during the rotomolding process. Preferably, the insert member is spaced from the inner walls of the tool assembly in order to permit mold material to flow and solidify in this space. The fixture assembly is removable from the interior of the molded unit through one or more access openings that are formed in the molded unit.Type: GrantFiled: February 12, 1997Date of Patent: June 15, 1999Assignee: Windsor Industries, Inc.Inventors: Hilogi Jesse El, Arlen Huff, Grant Oakes

Patent number: 5897817Abstract: Methods are disclosed for making semipermeable membranes from cellulose acetate and for making medical devices therefrom. In the process, a molten liquid comprising cellulose acetate (CA) is extruded to produce a membrane. The solvent and non-solvent are removed from the membrane to produce a semipermeable membrane having a water permeability. The semipermeable membrane is impregnated with a liquid consisting essentially of water to render the semipermeable membrane capable of being stored until time of use without undergoing a substantial loss in water permeability. The semipermeable membrane can be incorporated in a casing in order to produce a medical product, wherein the membrane is impregnated in the product.Type: GrantFiled: July 8, 1997Date of Patent: April 27, 1999Assignee: Althin Medical, Inc.Inventors: John M. Radovich, Melvin Rothberg, George Washington

Patent number: 5895619Abstract: The present disclosure sets forth both a method and apparatus for molding a unitary pig formed of two types of material, one being a light weight foam, and the other being a harder polymeric material thereby yielding a unitary harder material in the cast pig. The finished product involves N discs having parallel end faces and a central drilled core; the unitary cast harder material defines end located discs located adjacent to said foam core and a central core therein so that the end located discs adjacent to the foam donut are unitary with the core and bonded thereto.Type: GrantFiled: January 21, 1997Date of Patent: April 20, 1999Inventor: Kenneth M. Knapp

Patent number: 5885691Abstract: A process is disclosed for producing reinforced twin-sheet thermoformed articles comprising the steps of heating first and second sheets of thermoplastic material; forming the sheets in molds; heating a reinforcing insert of thermoplastic material; placing the heated insert on the first sheet in its mold at the location to be reinforced; pressing the second sheet into contact with the heated first sheet and the heated insert to form the insert between the sheets so that a fusion of the thermoplastic sheets and the insert takes place to produce a reinforced section of the article having a desired shape and thickness. Alternative processes are disclosed wherein a heated quantity of thermoplastic liquid material is extruded or injected between the first and second sheets within the first and second molds either by inserting the liquid material before the molds are closed or by injecting it through one of the molds.Type: GrantFiled: August 23, 1996Date of Patent: March 23, 1999Assignee: TriEnda CorporationInventors: Harlon W. Breezer, William F. Price

Patent number: 5855834Abstract: A method of production provides a plurality of conductors and a plastic-like material interlaced with the conducts in a woven pattern to hold and secure the conductors in a spaced relationship. The woven pattern of plastic-like material is formed by an injection molding process. The cable can have a plurality of conductors generally labeled as a first conductor, second conductor, and continuing to a last conductor held in a spaced relationship with each other, and each of the conductors has a beginning end and a terminating end. A narrow strip of the plastic-like compound forms a beginning base around the conductors, then it is woven over the first conductor, under the second conductor, over the third conductor ad continues in this woven pattern until the last conductor is included. Then the strip continues around the last conductor and is woven over the conductors in the opposite manner back to the first conductor, weaving the conductors together in a spaced relationship.Type: GrantFiled: April 9, 1996Date of Patent: January 5, 1999Inventor: Floyd Ysbrand

Patent number: 5846463Abstract: A window module has a fixed-pane window which is encapsulated by a molded trim piece having an integral portion which extends around an adjacent movable window opening. The integral trim is formed of EPDM. The window module is constructed by placing a window pane, a division post and the end of an extruded EPDM trim strip into a mold into which EPDM is injected to integrate and encapsulate the inserts.Type: GrantFiled: June 13, 1996Date of Patent: December 8, 1998Assignee: Kingston-Warren CorporationInventors: John D.

Patent number: 5840148Abstract: An improved identification marker and method of assembling the marker is provided, which includes the steps of providing a glass vial and filling the glass vial with a quick curing liquid to a predetermined volume corresponding to at least the volume wherein the unfilled volume of the vial is equal to the displacement volume of an IC circuit hybrid and antenna. The IC circuit hybrid and antenna are placed in the vial so as to be entirely enveloped by the liquid. A cap is placed on the vial and the liquid is cured. Preferably, the cap is an anti-migration cap so that when the transponder is implanted in an animal, it prevents the transponder from sliding out.Type: GrantFiled: June 30, 1995Date of Patent: November 24, 1998Assignee: Bio Medic Data Systems, Inc.Inventors: Neil E. Campbell, Donald J. Urbas

Patent number: 5840230Abstract: A process for the manufacturing of hollow fiber sections for hollow fiber modules is disclosed. The process includes a casting matrix having a horizontal perforated plate, in which a number of perforations are arranged in a predetermined pattern and continuous hollow fibers are introduced through the perforations. A hardenable casting material is cast for the formation of a solid tube plate. The tube plate with embedded continuous follow fibers is raised in a vertical direction to a desired distance from the perforated plate. The tube plate is cut in the horizontal plane to expose the follow fiber ends. The steps are repeated for the formation of a hollow fiber section.Type: GrantFiled: November 20, 1996Date of Patent: November 24, 1998Inventors: Svend Andreas Geleff, Knud S.o slashed.ndertoft Pedersen

Patent number: 5830401Abstract: A catheter is disclosed which includes a mechanical connection between the strain relief thereof and the hub. The strain relief operates both to secure the catheter tube to the hub and to provide strain relief for the catheter tube. The strain relief connection is assisted in gripping the catheter tube by intentional overstressing of the catheter hub during manufacture thereof to expand the hub wall and generate residual hoop stresses therein which assist in securing the catheter tube within the hub.Type: GrantFiled: February 25, 1994Date of Patent: November 3, 1998Assignee: Sherwood Medical CompanyInventors: James B.
