Fabrics comprising low-shrink polypropylene tape fibers comprising high amounts of nucleating agents
Publication number: 20040087233Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such tape fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. These inventive tape fibers (and thus the initial films and/or tubes) require the presence of relatively high amounts of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and allowing such an oriented polymer to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.Type: ApplicationFiled: September 4, 2003Publication date: May 6, 2004Inventors: Brian G. Morin, Martin E. Cowan, Jack A. Smith -

Patent number: 6139490Abstract: A stereoscopic endoscope system for producing images that can be perceived in three dimensions. An endoscope apparatus includes a sheath carrying a light source and two independent fixed lens endoscopes. Collimated light from the proximal ends of each endoscope are directed along folded optical paths to independent video cameras. The images generated by the video cameras energize monitors in a virtual reality display device that can be positioned proximate an observer's eyes. Adjustable mirrors and the provision of the rotation of at least one of the video cameras on its axis facilitate the alignment of the images for maximum effect.Type: GrantFiled: November 10, 1997Date of Patent: October 31, 2000Assignee: Precision Optics CorporationInventors: Robert S.

Patent number: 6132019Abstract: A door assembly that includes a door that is operable to alternatively expose and cover an opening in the bezel of a computer. The door assembly includes a carriage that slides up and down that pivotally couples to the door. Upon pressing against the lower portion of the door, the door pivots and the carriage and the door automatically slide down such that the door no longer covers the opening in the bezel. When an upward force is applied to the door, the door and the carriage move upward and into the closed position. As the door reaches the opening in the bezel, a spring forces the door against the bezel and into the closed position. The door is easily opened and closed and the door is out of the way when the door is in the open position.Type: GrantFiled: August 11, 1999Date of Patent: October 17, 2000Assignee: Silicon Graphics, Inc.Inventors: Sung Kim, Colin Alexander Davis, Ronald Jack Smith, Steven G. Siefert

Patent number: 5888193Abstract: An endoscope has an elongated sheath that follows a curved path. The sheath houses a plurality of relay lens sets designed to have a maximum usable field of view that is greater than the size of an image to be produced. Discrete lens elements within the image transfer guide allow the image to offset to the edges of the maximum usable field of view thereby to allow the axes through the individual sets to progressively shift in angle to form the curved path.Type: GrantFiled: November 10, 1997Date of Patent: March 30, 1999Assignee: Precision Optics CorporationInventors: Robert S. Breidenthal, Richard E. Forkey, Jack Smith, Brian E. Volk

Patent number: 5525756Abstract: A rodent-proof aerial splice closure (20) includes a substantially hollow casing (30, 31) having substantial externally exposed plastic areas. The casing sections (30, 31) are moveable with respect to one another on a hinge (35) for accessing the interior of the casing. Clamps (50) provide for reversibly holding the casing sections (30, 31) closed. Cables can enter and exit the closure (20) through cable ports (45), which can be sealed by end-pieces (55). The exterior geometry of the closure (20) is such that substantially all exposed plastic surface regions which are accessible to rodent teeth are rounded with curvatures preferably greater than one inch radii, thus large enough to prevent rodent teeth from biting down thereon.Type: GrantFiled: May 12, 1995Date of Patent: June 11, 1996Assignee: Raychem CorporationInventors: Julian S.

Patent number: 5359654Abstract: Modules integral with the body of the assembly include one for drop wire connections, one for subscriber wire connections, one for an electronics interface, and one for a network interface device. Protective sealant material within the assembly protects contacts from corrosion and other deterioration, and from shorting. Sealant plungers and a chamber containing a compressed gas impose compressive forces upon the sealant material. Shunt plugs associated with two of the modules permit signal transmission across the modules at desired times, and when removed eliminate the possibility of a subscriber being shocked or transmitting a spark when accessing subscriber components of the assembly. The main body and the modules of the assembly preferably are integrally connected and form a unitary sealed assembly.Type: GrantFiled: May 12, 1992Date of Patent: October 25, 1994Assignee: Raychem CorporationInventors: Michael L. Jensen, Thomas M. Baum, John E. Francis, John C. Mason, Jack A. Smith, Jr.

Patent number: 4998941Abstract: An adjustable door stop for a hinge mounted door having at least one hinge leaf connected to the door, one hinge leaf connected to a doorway, and a hinge pin. A body receives the hinge pin in order to rotate substantially perpendicular to the axis of the hinge pin. An adjustable mechanism extends from the body and rests against the doorway. A finger extends from the body substantially parallel to the axis of the hinge pin so that the hinge leaf connected to the door may rest against the finger, thereby stopping movement of the door.Type: GrantFiled: March 19, 1990Date of Patent: March 12, 1991Inventor: B.

Patent number: 4211995Abstract: A self contained alarm device is disclosed for aiding in the prevention of the theft of articles from an automobile, such as a citizens band radio, by sounding an audible alarm in the event of an attempted theft. The device includes a box or container in which the article to be protected is mounted and at least one switch mounted on the outside of the container for articles, and at least one switch between the container for the articles and the lid for the container so that removing the container from the surface on which it is mounted will cause an audible alarm to be sounded. One embodiment of the device also includes an electrically conducting wire forming a loop outside of the container for encircling an element of the automobile such as the steering column so that if the loop is cut, the audible alarm will also be sounded.Type: GrantFiled: September 20, 1976Date of Patent: July 8, 1980Inventor: Jack Smith
