Abstract: A cargo-carrying vehicle has a plurality of flooring members. A pair of parallel, spaced-apart frame rails confines the flooring members therebetween in closely spaced adjacent relation to form a floor surface. A pair of end members extends transversely between the frame rails at the ends thereof to secure the frame members against movement parallel to the frame rails. At least one of the end members is selectively moveable relative to the frame rails to permit selective removal of one or more of the flooring members from between the frame rails.

Abstract: A method of installing fibre optic cables consists of cutting a shallow and narrow trench or channel within a road surface or building wall. A narrow fibre optic cable is laid within the channel, and subsequently covered with a patch material. A branching cable network is provided by cutting at periodic and selected locations, a slightly broader and deeper region of the channel, within which cable loops and/or junction boxes are installed. The nodes may consist of branching nodes, or alternatively non-branching nodes containing a cable loop and/or junction box, the installation of which at a location permits a junction node to be formed at a close by location. The invention also consists of a junction box for use with the system.

Abstract: The present invention discloses a unique and novel display device for attaching an auxiliary lens assembly to a primary lens assembly. A display mount is disclosed that allows auxiliary eyewear to be displayed along with the primary eyewear to which it combines. The primary lens assembly can be supported in a conventional manner in an existing display rack. The auxiliary eyewear display mount is attachable to the bridge portion of the primary lens assembly with a hand-operated clamp. An arm extends from the clamp to an auxiliary cradle that supports the auxiliary lens assembly.

Abstract: A primary assembly includes a primary frame that secures a pair of primary lenses in position relative to one another. A primary extension is located on the outer periphery of each end of the primary frame and has an aperture formed therein extending generally parallel to the primary lenses. A pair of arms is connected to each one of the primary extensions by a hinge. An auxiliary assembly includes an auxiliary frame that secures a pair of auxiliary lenses in position relative to one another. A pair of auxiliary extensions is positioned on each end of the outer periphery of the auxiliary frame. The auxiliary extensions are adapted to be received in the apertures in the primary extensions, wherein the auxiliary assembly is removably secured to the primary assembly.

Abstract: The present invention discloses a unique and novel system for attaching an auxiliary lens assembly to a primary lens assembly in which the attachment includes two alternative positions, a lowered position and a raised position. In the lower position, the person wearing the eyewear system views through both the primary lenses and auxiliary lenses. In the raised position, the person wearing the eyewear system views only through the primary lenses. As a further option, the auxiliary lens assembly is easily removable from the primary lens assembly, allowing for separate storage of the auxiliary lens assembly when not needed. Slotted extensions on the primary lens frame receive retainers attached to auxiliary extensions on the auxiliary lens assembly. Each auxiliary extension has a rocker pivotally attached to a keyseat. An internal spring urges the rocker into snap alignment with the surfaces of the keyseat.

Abstract: An eyewear assembly comprises a primary frame assembly 100 having an outer periphery and a primary lens holder 102. At least one primary lens 106 is carried by the primary lens holder. One of a pair of arms 108 extends from a hinge 110 at each outer periphery of the primary frame assembly. An auxiliary frame assembly 200 has an outer periphery with auxiliary extensions 208 and an auxiliary lens holder 202. At least one auxiliary lens 206 is carried by the auxiliary lens holder, wherein the auxiliary frame assembly is removably secured to the primary frame assembly between the hinges and arms, so that the auxiliary lens is maintained between the primary lens and an eye of the wearer and the forward aspect of the primary assembly is undisturbed.

Abstract: A roller cone body defines a circumferential channel or race into which a plurality of cutter or wear segments are mounted. The wear segments may be of any appropriate contour or shape, such as for example chisel, spherical, or even flat face and are preferably made or carbide. The wear elements may be all the same within a channel or race, or they may be varied within a race as needed for a particular application.

Abstract: The present invention comprises a tamping tool comprising a shank and a blade, with the blade having various arrangements of wear-resistant material affixed to the face of the blade by means of brazing, soldering, gluing or other method. Additionally, some arrangements of the tamping tool have a wear-resistant tip inserted into a groove in the end of the blade. The tamping tool of the present invention reduces wear, providing an increased life and increasing the time intervals at which it becomes necessary to replace the tamping tool.

Abstract: Attaching a labyrinth seal composed of wear-resistant material to the surfaces of rotating equipment subject to wear can increase the life of the rotating equipment and reduce down-time for equipment maintenance and repairs.

Abstract: A screw rotates in a containment barrel, and comprises a shaft having an upstream end and a downstream end At least one flight is secured to the surface of the shaft and extends helically in successive turns around the circumference of the shaft. An upstream barrier member extends radially from the surface of the shaft and generally transversely between successive turns of the flight. The upstream barrier is disposed proximal the upstream end of the shaft. A downstream barrier member extends radially from the surface of the shaft and generally transversely between successive turns of the flight. The downstream barrier is disposed proximal the downstream end of the shaft.

Abstract: The present invention relates to eyewear, and in particular, for a single block assembly having multiple slots and reliefs in substantial alignment for accommodation of a flange for lens attachment, a flange for arm attachment, a magnet location, and an accessory slot. The accessory slot can accommodate attachment of a variety of accessories, including a pivotal auxiliary lens assembly, a stationary auxiliary lens assembly, or a tether cord. The single block design provides a reduced profile which allows the frame to accommodate wider lenses for improved peripheral visibility and improved appearance.

Abstract: A method and apparatus for making can lid shells in die presses, with the addition of a forming ring within the die set. The forming ring is placed between the draw pad and die center, and is used to apply a force on the material during the shell lid forming process. Use of this apparatus reduces the amount of force that must be applied on the draw pad to hold the material between the die core ring and the draw pad during the forming process. By lessening the force needed to hold the material during the forming process, the probability of wrinkling or cracking of the material during the forming process is greatly reduced.

Abstract: An eyewear assembly comprises a primary lens assembly that includes a primary frame that secures a pair of primary lenses in position relative to one another and a pair of primary extensions, each positioned on an outer periphery of the primary frame. Each of a pair of arms, is connected to one of the primary extensions by a hinge. An auxiliary lens assembly includes an auxiliary frame that secures a pair of auxiliary lenses in position relative to one another and a pair of auxiliary extensions, each positioned on an outer periphery of the auxiliary frame. A lug is carried on each of the primary extensions and moveable on and relative to the extension, each lug adapted to receive a portion of one of the pair of auxiliary extensions, wherein the auxiliary lens assembly is removably secured to the primary lens assembly and the auxiliary lens assembly moves with the lugs.
