摘要： A trip hazard measurement gauge has an outer tube with a stationary foot secured to a lower end thereof, and an inner tube slidable within the outer tube and extending through an upper end of the latter. The inner tube has a slidable foot secured to a lower end thereof and a ruler secured to an upper end thereof. The inner tube is spring biased in a downwardly direction. With the inner tube positioned at its downward limit, the stationary foot and the movable foot are equiplanar and the ruler is hidden inside the outer tube. An estimator measures a difference in elevation between two adjacent concrete slabs by placing the slidable foot on an adjoining edge of the uppermost slab and pushing down on the outer tube until the stationary foot contacts the lowermost slab. The ruler, extending upwardly from the outer tube, indicates the difference in elevation.

摘要： A dust abatement vacuum hood, provided for a flush-cutting concrete saw, includes a rigid shell that is preferably either vacuum formed or injection molded from a tough polymeric material that may be reinforced with structural fibers. Alternatively, the vacuum hood may be stamped or cast from a durable metal. The vacuum hood is equipped with a vacuum port to which one end of a vacuum hose may be attached. The opposite end of the vacuum hose is attached to a vacuum cleaner system. The vacuum hood has a spring-mounted attachment bracket that can be bolted directly to the concrete saw. As the blade of the concrete saw rotates, pulverized concrete is discharged into a chamber opening of the vacuum hood. Internally, the vacuum hood is shaped so that the pulverized concrete is directed toward the vacuum port, from where it is directed to the vacuum cleaner system.
