  • Patent number: 7247012
    Abstract: A polymer extrusion crosshead assembly for forming a spirally-striped extrusion. The assembly includes conventional components for admitting, turning, and accelerating primary molten polymer toward a novel rotating die sub-assembly. A body element includes an axial counterbore for receiving a manifold supply block in communication with a source of secondary striping polymer. A wear plate is attached to the manifold block. The die sub-assembly includes a striping die having an annular passage for conveying the primary polymer to form an extruded tube or a core material coating. The die is loaded against the wear plate by a Belleville washer. The die includes one or more striping nozzles in communication with the manifold block for injecting secondary striping polymer into the annular stream of primary polymer flowing through the die, creating a longitudinal stripe of striping polymer. Rotating the die while extruding both polymers yields a helically striped (spiral) extrusion.

  • Patent number: 7224244
    Abstract: The length of a transmission line delay circuit is halved by inserting a directional coupler in the signal path ahead of the transmission line and either open circuiting or short circuiting the other end of the transmission line. The signal traveling through the directional coupler and through the transmission line is reflected back at the end of the transmission line, and the reflected signal is carried to the coupled output of the directional coupler. Since the signal travels through the transmission line twice, the delay time is doubled. Therefore, for a given delay requirement, the length of transmission line required is only half of the length required for prior art transmission delay lines.

  • Patent number: 7174821
    Abstract: A punch for attachment to a brace of a braced die has a hollow cutting nose with a leading end for cutting a material to be punched and a trailing end opposite the leading end. A shaft extends from the trailing end of the nose and is sized to pass through an aperture in a brace. An upper retainer is joined to the shaft and has an upper retaining surface adapted to abut an upper surface of a brace. A lower retainer is joined to the shaft and has a lower retaining surface adapted to abut a lower surface of a brace. An internal waste evacuation chute extends from the interior of the hollow cutting nose and through the shaft for evacuating plugs of punched material from the nose.

  • Patent number: 7121182
    Abstract: A steel rule die for cutting cloth and synthetic materials. The cutting die includes a primary substrate and a plurality of cutting units that are removably attachable to the substrate in such a manner that they are easy to adjust, remove and replace. The cutting units include secondary substrates with lengths of steel rule attached to them. The cutting units are secured to the primary substrate. Each steel rule is fixedly attached to a secondary substrate that is substantially harder than the primary substrate. The secondary substrate distributes the cutting load applied to the rule over a large surface area on the primary substrate to prevent the cutting units from diving into the soft primary substrate. Substantially the entire length of the steel rule is supported by the secondary substrate, thereby yielding a rigid cutting unit that is not susceptible to deformation.

  • Patent number: 7114462
    Abstract: The automated cage cleaning system is comprised of a pair of robotic arms, a soil side robot and a clean side robot. The soil side robot is utilized for removing the dirty cage bottoms from a cart, rack, pallet, or fixture, emptying soiled bedding from the cage bottoms, and placing the cage bottoms on a conveyer leading to the tunnel washing equipment. The clean side robot is used to grip the clean cage bottoms, and place the cage bottoms on a cart, rack, pallet, or fixture. Additionally, the present invention comprises an optical arranger robot with vision processing for detecting, and moving skewed cage bottoms to a re-grip station. From the re-grip station, the clean side robot places the cage bottoms on a rack, pallet, fixture, or any other device suitable for holding a plurality of cage bottoms.

  • Patent number: 7100406
    Abstract: A locking mechanism that allows a live bolt lock plate and a primary vertical lock plate to move relative to one another irrespective of the plates connection with a drive mechanism is provided. The drive mechanism includes first and second gears and is used to move the locking mechanism between locked and unlocked positions. The live bolt lock plate has a slot defined therein and is engaged with the first gear of the drive mechanism. The primary lock plate is engaged with the second gear of the drive mechanism and has a guide pin mounted thereon. The guide pin is positioned within the slot to slidingly couple the live bolt lock plate and the primary lock plate, in addition to their connection with the drive mechanism. A tumbler stack is associated with the primary lock plate for selectively allowing the primary locking plate to be moved to the unlocked position.

  • Patent number: 7090060
    Abstract: A torque fuse device having a bi-directional release mechanism that releases the torque carrying capability of the shafts upon torque overload is provided. The torque fuse device includes a sleeve, a hub positioned within the sleeve, and a hydraulic torque coupler. The sleeve and the hub are adapted to be coupled with two axially aligned shafts. The hub includes a feedback ring having at least one tooth formed therein. The hydraulic torque coupler includes a piston, a cylinder and a collet. The piston is positioned between the collet and the feedback ring and slides along an inclined surface of collet. One ore more fuse pins are selectively positioned between the tooth, the piston and the cylinder to frictionally engage the sleeve to the hub. Upon a torque overload condition, the pins release from the teeth thereby releasing the torque carrying capability of the shafts.
