  • Patent number: 6330949
    Abstract: Embodiments of a hanger system are shown and described, each embodiment including a support member and at least one looped cord hanging from the support member. The looped cord includes a cleat or other adjustable fastener for adjusting the diameter of the loop, so that is fits around and securely holds differing sizes of items in the loop, preferably, up off of the ground or floor. The cleat may have sharp exterior corners and notches for gripping an item being held, and sharp interior hole corners for gripping the cord. An attractive hanger may be constructed by using an elongated, straight, narrow bar of wood, plastic, or metal, that has holes bored through it to receive and capture knots in the ends of the cords. Thus, several cords may hang from the support member, spaced several inches or more from each other, so that the cords hang down without tangling and the suspended items do not significantly interfere with each other while hanging or while being hung or removed.

  • Patent number: 6308966
    Abstract: A braking and steering mechanism that is located near, but behind the steering pivot point of a runner of a ski vehicle. In a conventional snowmobile, for example, the steering pivot point is near the middle of the longitudinal axis of the runner, and, hence, the preferred braking and steering mechanism extends from behind the middle of the runner, but not at the rear end of the runner, to contact the snow or ground to slow or stop the snowmobile movement relative to the snow or ground. The preferred braking and steering mechanism has a brake that is a retractable, protruding member that extends down from the runner bottom surface near, but behind the steering pivot point a sufficient distance to frictionally engage the snow/ground significantly more than does the bottom of the runner. The protruding member may take the forms of a prong or spike, a blade or plate, or other single, plural, smooth or toothed member(s) that can make frictional contact with the snow/ground.

  • Patent number: 6238812
    Abstract: A semiconducter battery that utilizes radioactive decay processes to produce electrical power by direct electrical current generation from these decay products. These batteries have extremely long half-lives. Each decay can produce on the order of 1,500,000 free electrons and 1,500,000 ions per each radioactive decay, so there is a tremendous multiplication factor for current generation. Production of these batteries by semiconductor processes greatly reduces battery cost compared to existing batteries that utilize radioactive decays. The battery comprises a n-type semiconducter layer, a radioactive semiconducter layer sandwiched between two adjacent layers of semiconducter material not containing radioactive material, and a p-type semiconducter layer.

  • Patent number: 6201314
    Abstract: Various embodiments are described of a liquid-powered dynamometric generator built into a shoe, which has at least two layers as part of its sole. The first or lower layer of the sole is a pad formed of an elastomeric material which contains a liquid within a set of chambers, one in the heel area and one in the toe area of the sole. The ambulatory foot movement inside the shoe puts pressure on the fluid and makes it flow from one chamber area to another. Contained between the chambers is a turbine that is mounted on rotary bearings and positioned within the path of the fluid flow. Due to foot motion, the fluid will flow in an oscillatory fashion while ambulating and thereby cause the turbine to turn.

  • Patent number: 6196765
    Abstract: A process for treating earth materials such as rock heaps to prevent acid rock drainage therefrom is disclosed. First, the oxygen concentration in the gas-phase of the rock heap is decreased, that is, displaced and/or depleted. This first step may be accomplished physically, chemically or biologically. Then, the gas-phase oxygen concentration in the heap is maintained at a low level. This second step may be provided for in a self-sustaining manner, like, for example, by covering the rock heap with soil and vegetation so that acid rock drainage is prevented indefinitely. Alternatively, the density of the gas-phase of the rock heap may be increased, and maintained at an elevated level indefinitely. The process is applicable to waste heaps from mining and industrial operations such as power generation and minerals processing, and to rubble collections in open and closed mines.

  • Patent number: 6193258
    Abstract: The present invention is a device for aligning the trailer hitch ball on the towing vehicle, and for lifting the trailer hitch on and off the ball. The device comprises a swiveling vertical post assembly in close proximity to the hitch ball. The swiveling vertical post assembly pivots at its attachment point with the towing vehicle, thereby allowing the user to load or unload a trailer from the vehicle even when the trailer is not perfectly aligned directly behind the vehicle. The swiveling vertical post assembly has a pivotal arm which can be moved from an upper pivot point position to a lower pivot point position. In both the upper position and the lower position, the pivotal arm is allowed to rotate from a generally vertical position to a rearwardly inclined position in order to provide a moving cable guide that helps determine the location and direction of movement of the cable and hence the forces exerted on the tongue end.

  • Patent number: 6191685
    Abstract: Embodiments of an alarm system are described, which may be mounted or built-in to a bicycle or other device which is in need of anti-theft protection. A loud alarm is connected to or mounted in the protected device, and is operatively connected to either or both: a lock that anchors the device to a stationary object, and/or parts of the protected device that might be stolen or vandalized. The alarm unit is built and wired in such a way that the lock or parts of the protected device may not be significantly tampered with or removed without triggering the alarm. For example, the alarm system is adapted to sound if a bicycle lock is tampered with or if sensors transmit that a bicycle part is being moved or tampered with. Externally-mounted alarm units preferably include a weather-proof casing, which contains a unique clamping feature that makes the alarm tamper-resistant or tamper-proof.

  • Patent number: 6186875
    Abstract: A machine for lapping bowling balls and, thus, re-rounding, smoothing, and cleaning the balls. The machine is comprised of three concave abrasion blocks with drive motors, adjustable mounting brackets attached to an adjustable support table, a catch basin with filter to separate suspended solids from liquids, and a pump and fluid delivery tube to deliver flushing and/or cleaning liquids. The abrasion blocks are comprised of resilient concave blocks with abrasive sanding disks. The positions of all three abrasion blocks are preferably simultaneously and equally adjusted by small adjustments to the position of a top table relative to the stand that holds the pivotal motor mounts. Ramps on the rotatable table cooperate with the mounts to slightly pivot the motor mounts inward and outward from the ball, changing the orientation and distance of the abrasive blocks relative to each other and, hence, to the ball.
