  • Patent number: 7209320
    Abstract: A disc assembly in a disc drive includes a hub rotatable about a central axis. Pluralities of disc elements are mounted about outer periphery of the central axis of the hub. An annular shaped disc clamp is located about a first axial end of the hub, the annular shaped clamp holding the outermost disc to the hub by a series of equally spaced fasteners along an inner diameter of the disc clamp. The improvement therein consisting of placing an offset angle on the underside, or disc-to-hub contact area. The offset angle sloping from the inner disc contact point outward to the end of the clamp such that application of pressure during clamping will make a uniform contact area along the clamp surface as the clamp fasteners are tightened to secure the clamp to the hub. This improves flatness, axial run out, reduces repeatable run out and increases reliability.

  • Patent number: 7093824
    Abstract: A portable fencing system in a barricade or corridor arrangement utilizes at a minimum one each of a corner post fixture, and a fence wire. In an enclosure arrangement, the portable fencing system can utilize at least one winch corner fixture, a plurality of corner post fixtures, a plurality of spacer posts and a plurality of fence wires. Spacer posts are spaced from one another and from a winch corner fixture and corner post fixtures such that the winch corner fixture, corner post fixtures, spacer posts and fence wires all together can form any suitable arrangement in relation to one another to provide an enclosure barrier around an area or a barricade or corridor along a side of an area.

  • Patent number: 7078621
    Abstract: Lightning at or near the site of an oil storage tank can cause a charge build up in the tank. This charge must be discharged to ground at rapid speeds to prevent arcing, sparks and fire. The tank has a metal floating roof which can be used to discharge the charge to ground by connecting a low impedance braided wire to the floating roof, and then connecting the wire to a take up reel at the top rim of the tank. The take up reel keeps any slack out of the wire. The path to ground is liquid to floating roof, to braided wire, to take up reel, to wall of tank, to earth ground.

  • Patent number: 7075421
    Abstract: A tire monitoring system providing tire status and notifying or warning the vehicle operator of early detection of imminent tire failure and performance degradation; thus improving safety by preventing blowouts from occurring, lengthening tire life by encouraging preventive maintenance, and improving fuel mileage by encouraging the operator to fill the tire to its proper pressure or repair it. The system monitors temperature of the rim of the wheel to which the tire is attached, such temperature being transmitted to the vehicle operator or other interested parties via means such as radio frequency.

  • Patent number: 7056188
    Abstract: The present invention discloses an automated rock saw having a saw motor load sensor to control the speed of the conveyors bringing the rock to the saw blade. As the saw motor works harder to cut a given rock, the controller automatically slows the conveyor belts, reducing the load on the saw blade. If the saw blade is easily cutting a given rock and not working at optimum speed, the conveyors will be sped up, increasing production. Also provided in an alternate embodiment is a horizontal blade that can be moved into place to cut the “bottom” of a corner piece, then the standard, vertical blade cuts the other side of the corner.

  • Patent number: 7048015
    Abstract: A portable electrically powered clamp application tool has a bench mounting kit with a foot pedal control for bench work. The tool has two grippers which enable a powered clamp cutting operation, wherein the only manual step is bending the tightened clamp prior to triggering the cutter arm. A gripper element is non-rotational and has teeth. It locates the material being gripped in a repeatable manner in spite of oil or other lubricants on the clamp. After the cutting operation an automatic release assembly releases the clamp. A manual lever(s) can also release a tail of a clamp.

  • Patent number: 7045359
    Abstract: The present invention relates to an apparatus and method for determining the concentration of nitric oxide (NO) in a gas mixture such as air. The gas sample containing NO is mixed with a gas containing ozone (O3), and the change in the ozone concentration is measured after a sufficient time is allowed for the reaction between NO and O3 to take place and destroy a measurable quantity of O3. In the disclosed embodiment, the concentration of ozone is measured using the technique of UV absorption. In this case, the invention has the advantage over other instruments for measuring NO of having absolute calibration based on the known extinction coefficient for ozone at ultraviolet wavelengths. The invention discloses both static and dynamic flow systems, and the NO concentration measurements may be made over a wide pressure range.

  • Patent number: 7020968
    Abstract: A coring tool is designed to first pierce the skin of a fruit and/or vegetable such as a pepper. A second phase blade of the coring tool preferably has a pair of oval blades, each with a sharpened leading edge to core the inside of the pepper. Thus, the two phase tool allows the user to easily cut through the skin of the pepper making a small. Neat hole, and then push the tool further into the center of the pepper, thereby coring the center. A hand held stirrer is shown powering the coring tool.

  • Patent number: 7017739
    Abstract: Plastering/cement trowels have sharp edges which can cut a worker when he places the trowel down in a resting position. The present invention provides a plastic sheath to insert the trowel into during the resting mode of use. This sheath also prevents nicks and dents to the trowel while it is transported. An optional sharpening file is attached to the top of the sheath. Various sheath embodiments include a narrowed rear section of a longitudinal slot on the upper member which functions to hold the spine of the trowel in the slot, a rubber membrane stretchable over the blade, a pair of pincer members on the top of the sheath to lock the shank of the trowel into the sheath, a tether on top of the sheath to lock the shank of the trowel into the sheath, and a rear door for the blade slot.
