Patent number: 6156402Abstract: A wooden flooring strip having a wooden flooring strip, comprising a top surface and a base surface opposed to the top surface, the top surface and the base surface defining between them a predetermined thickness wood flooring material. The predetermined thickness wood flooring material includes a top surface zone adjacent the top surface and a base surface zone adjacent the base surface. The base surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the base surface and thereby increase the flexibility of the flooring strip for more closely adhering to a sub-floor. The top surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.Type: GrantFiled: April 30, 1999Date of Patent: December 5, 2000Assignee: Triangle Pacific Corp.Inventor: William S. Smith

Patent number: 6053198Abstract: A fluid control system that includes a fluid manifold having a plurality of manifold bodies fastened to each other end-to-end so as to form at least first and second passages extending continuously through the manifold and each of the bodies. A plurality of solenoid valves are each mounted on a side of an associated body with valve ports opening into the body to the fluid passage(s) that extend through the manifold. An electrical connection arrangement is mounted at one end of the manifold for receiving control signals from an external source. A plurality of circuitboards are disposed one within the second passage of each body, with each of the circuitboards including male and female connectors at opposed ends for connecting the circuitboards in series with each other to the electrical connection arrangement at the end of the manifold.

Patent number: 5736227Abstract: A wood flooring product for assembly into a wood floor is disclosed. The flooring product includes a top, decorative layer, an intermediate layer bonded to the top layer, and a base layer bonded to the intermediate layer. The top, intermediate and base layers are bonded in registration to define a laminated elongate wood flooring strip. A tongue and a groove are formed on respective side edges of the flooring strip. The tongue and groove extend along the length of the flooring strip, and lock adjacent flooring strips together side-to-side to form an assembled wood floor.

Patent number: 4359107Abstract: The improved shut-off apparatus for pneumatically driven tools includes an auxiliary shut-off valve located in the flow passageway. The valve is controlled by a control rod which extends through the air motor into engagement with a latching device. The latching device is held in the latched position with the valve open by a movable weighted control member. The movable weighted control member is responsive to inertia so that as the speed of the air motor decreases due to a torque load imposed thereon, the shaft slows causing the inertial movement of the weighted member to release the latching device permitting the auxiliary shut-off valve to close.Type: GrantFiled: May 15, 1981Date of Patent: November 16, 1982Assignee: Dresser Industries, Inc.Inventor: William S.
