  • Patent number: 6637112
    Abstract: A deflectable safety shield extends transversely across a cutting plane in a protective guard position completely overlying the cutting edge of a utility knife. A portion of the shield extends over-center with respect to the cutting edge, thereby tending to hold the shield in the guard position in response to contact of the shield against the operator at the normal angle of engagement during follow-through that accompanies rapid slicing hand movements. The shield is resiliently biased for movement to the guard position by a torsion spring. An outwardly-turned flange portion of the shield provides an angularly offset leverage point for reacting the torsion spring when the operator desires to perform a cutting operation. The shield swings away from the cutting plane automatically in response to pressure engagement of the offset flange portion against the box surface, thus exposing the cutting edge.

  • Patent number: 6619697
    Abstract: An existing protective duct contains a bundle of guide tubes through which fiber optic cables are run to customers at existing service locations. In order to run a cable to a new customer at a different service location, the duct is cut at a branch point and a short section of the duct is removed to expose the guide tubes. An unused guide tube is cut and serially connected to a branch guide tube leading to the new service location. The protective duct sidewall is restored at the branch point by a splittable Y-branch connector that includes complementary housing sections, an inlet opening, an outlet opening and at least one branch opening. Splittable coupling collars seal the branch connector housing sections around the respective cut end portions of the existing duct. The Y-branch connector also includes a branch stub that is sealed around the branch guide tube.

  • Patent number: 6582291
    Abstract: A roof-mounted wind turbine includes turbine vanes that are linear-shaped and do not have the conventional convex curvature. Additionally, the turbine vanes are made in common with one another or with a common turbine component, so that each vane does not require individual handling nor individual attachment to the turbine assembly as is required in the construction of conventional wind turbines that are commercially available today. This is accomplished by producing the vanes by molding or extruding techniques that are commonly used in making plastic assemblies or components.

  • Patent number: 6550818
    Abstract: An adjustable bent sub assembly is provided comprising a tubular adaptor for connection with the stator of a downhole motor, a tubular adjusting ring for altering the angular offset of the assembly, and a tubular offset sub for connection with the bearing and bit assemblies. A tubular mandrel is positioned internal of this stack of components. The mandrel is threadably connected at its upper end with the adaptor and at its lower end with the offset sub. The mandrel and ring have a spline connection. The ring and offset sub have disengagable dog clutch means connection them. The mandrel is transversely bent at a point along its length as is the offset sub. The ring has an angled or canted bottom end face. The combination of bending the internal mandrel, bending the offset sub and canting the end face of the ring results in the effective or resultant bend point of the assembly being closer to its lower end.

  • Patent number: 6543140
    Abstract: A utility knife and various manufacturing methods for the utility knife. In one embodiment, the utility knife includes: (1) a body having a cutting face and (2) a blade-holding slide mounted for linear movement within the body and having a knife-holding head extendable through an opening in the cutting face. The opening has aparallel opposing sides that diverge toward a cutting direction of the utility knife. The knife-holding head has corresponding aparallel opposing sides that cooperate with the sides of the opening to cause a cutting force exerted on the knife-holding head to wedge the blade-holding slide within the opening and thereby stiffen the knife-holding head with respect to the body during operation of the utility knife. In one embodiment of the present invention, the blade-holding slide resiliently urges the knife-holding head to unwedge when the cutting force is removed therefrom.

  • Patent number: 6487949
    Abstract: A bale processor for cutting or dicing a bale or slab of unvulcanized rubber produces small cubes or blocks of a predetermined size and uniform shape for continuous feeding at a predetermined rate into a mixing machine or blender. A bale or slab of feedstock rubber is advanced incrementally along a slider platform and a segment is sliced from the leading end of the bale. After separation, the segment falls onto a receiving panel from which it is transferred by a vacuum pick-up head to a vacuum hold-down table. Multiple slices are then formed through the segment along the X-axis by circular cutting blades of an X-axis cutter head, thereby forming elongated segment strips. Next, multiple slices are formed through the segment strips in the Y-direction by a Y-axis cutter head which includes circular cutter blades that are extendable and retractable along the Y-axis.

  • Patent number: 6446972
    Abstract: A wagering card game is played with a standard fifty-two card poker deck and a count limit card that is permanently assigned as the third card of the dealer's hand. Each player makes a bet. Three cards are dealt face down to each player, to the dealer and to the bonus hand. The players inspect their cards and have the option of trading one card. The dealer burns his top card and reveals his first two cards. The dealer's third card is a count limit card or the representation of a count limit card having a predetermined count value (for example 3) that is imprinted on the count limit card or on the playing surface, and is displayed at all times. The dealer combines his dealt cards with his count limit card and states his total. He then turns over each player's cards one at a time, compares each player's hand with the dealer's hand, determines whether the player is a loser or winner, pays or collects on the winner's and loser's hands, respectively.
