摘要： A level apparatus for spanning two spaced apart building structure points and indicating whether the points are level relative to each other includes an elongate tubular segment having a tubular segment longitudinal abutment face for abutting a building structure point; an extension segment slidably retained within the tubular segment for slidingly extending partly out of the tubular segment and having an extension segment longitudinal abutment face for functionally extending the tubular segment longitudinal abutment face when the extension segment is extended; and a longitudinally oriented bubble site glass. A method of testing whether first and second spaced apart points on a building structure are level relative to each other, using the above-described apparatus, includes the steps of pulling the extension segment outward from the tubular segment; placing the tubular segment against the first building structure point and the extension segment against the second building structure point; and observing the position of the bubble in the site glass to determine whether the first and second building structure points are level relative to each other.

摘要： Method comprises positioning a spray gun and its cup-connecting means in a stationary support, and its gun cup in a rotatable cup holder in a closed chamber. Then, compressed air and cleaning liquid is passed through the gun and cup-connecting means, while simultaneously rotating the cup holder and spraying the exterior surfaces of the cup, gun, and cup-connecting means and the interior surfaces of the cup. In a preferred embodiment, the spray from the gun rotates the cup holder. The device comprises the chamber, the gun support, a rotatable cup holder, a pool for cleaning liquid, spraying means, internal means for filtering and distributing cleaning liquid to the cup connecting means and the spraying means, and means for introducing compressed air from outside the chamber into a compressed-air manifold and then distributing the compressed-air to the gun and spraying means. The device also includes means for venting air that is exhausting from the chamber and means for absorbing fumes in the exhausting air.

摘要： A phosphorescent keyhole locator particularly adapted for use in combination with a tumbler-type lock comprising a cylindrical tumbler having a circular tumbler end surface with a keyhole therein, and a peripheral end surface around the tumbler end surface. A solid phosphorescent plastic body having an aperture therethrough is adhesively attached to the peripheral end surface with the aperture positioned over the tumbler end surface. The aperture is at least about as large as the tumbler end surface and has straight sides which may be normal to or bevelled towards the tumbler end surface.
