  • Patent number: 8157201
    Abstract: A container for the dispensing of wire or cable has an external carton which receives a reel of cable supported by two caddies. Each caddy has an inwardly extending substantially cylindrical bushing which is received in a central hole of a respective cable reel flange. The cylindrical bushings are disposed on an axis which is a first distance from an upper surface of a bottom panel of the carton. The largest radius of the reel flanges is preselected to be smaller than this first distance such that the reel may freely rotate inside of the carton on the bushings. Cable is pulled through a slot in the carton's front panel. Left and right panels of the carton each have an arbor hole formed therein which may receive an axial rod, the rod also extending through the reel and caddies. The axial rod may be used to join two or more cartons together and may further serve as a support for attachment to a dolly, hand truck, or four-wheeled cart.

  • Patent number: 7121872
    Abstract: In an electrical connector suitable for a multistranded insulated conductor, a frustoconical collar is so dimensioned that it will exhibit physical interference with a housing bore into which the conductor and the collar are inserted. As the collar is advanced into the bore, fingers of the collar more tightly grip the external surface of the conductor. A cap affixes the conductor and collar to the housing to complete the connection.

  • Patent number: 7097576
    Abstract: A bearing assembly is at least partly disposed within the hollow stem or handle of a sports racquet. A plurality of curvilinear channels are disposed at different lateral locations in a direction which is at a substantial angle to the longitudinal axis of the racquet. For each channel there are provided a pair of ferrules through which string segments are strung from, and then back to, the string bed. Preferably the ferrules receive ends of tubes through which the string segments are strung. One embodiment receives most of the main strings of the sports racquet, while another embodiment receives all of them. In one embodiment the bearing assembly also forms the end cap of the racquet handle.

  • Patent number: 6803912
    Abstract: A real time three dimensional multiple display imaging system has a central processing node and a plurality of remote, virtual camera processors. Each of the virtual cameras has its own predetermined viewpoint and is capable of displaying a scene into a virtual world from that viewpoint. The virtual world and the objects displayed in it are controlled by the central processing node. Geometric and textural data concerning the objects are stored in advance by memories associated with each one of the virtual cameras, thereby reducing the amount of communication bandwidth necessary for real-time animation.

  • Patent number: 6796829
    Abstract: The subject invention relates to an electrical connector for coupling to an insulated single conductor electrical cable or to a coaxial cable, the latter being of the type having an inner conductor enclosed in an inner concentric insulation and having a generally concentric conductive sheath therearound and an outer insulation enclosing the conductive sheath. The subject connector includes a housing having an electrically conductive portion and a bore therein. One or more conductive arms can be disposed in the bore and electrically connected to the conductive housing portion and have pointed ends sized for piercing the outer insulation of the insulated electrical conductor. A closure member is included for closing the open end of the above and for forcing and/or securing engagement of the pointed ends of the conductive arms through the outer insulation of an electrical cable.

  • Patent number: 6796916
    Abstract: A racquet for hitting a projectile has a stem, which is a handle or a shaft with a handle, and a racquet head with a frame extending from the handle and supporting a tensioned string bed defining a sweet spot. The frame has an upper portion on an opposing end of the frame relative to the handle and a longitudinal axis extending from the upper portion to the handle. The string bed includes main strings generally running parallel to the longitudinal axis and cross strings running generally perpendicular to the longitudinal axis. The string bed has an upper end defined at an interior surface of the upper portion and a lower end disposed at an interior surface of a lower end of the frame near the handle. A length is defined from the upper end to the lower end of the string bed. The cross strings are only disposed at most within approximately an upper 70% of the length of the string bed.

  • Patent number: 6735819
    Abstract: A vehicle floor mat affixation device includes a noncircular shaped body with an axial extending connector. The connector secures the affixation device to the vehicle floor. A reverse face of the affixation device includes a panel of releasable fastening material that is designed to mate with a similar panel of releasable fastening material in the vehicle floor mat. The present invention resists affixation device pull-out as well as shear forces applied to the mat with respect to the carpeting on which the mat is placed, but nonetheless permits easy removal and replacement of the vehicle floor mat and of the affixation devices without tools.
