Abstract: A carpentry tool for pushing flooring boards into contact on a joist can be operated with one hand, leaving the carpenter's other hand free for hammering. The tool includes a body member having offset clamping lugs for engaging each side of a joist. A cam lever pivotally mounted at one end of the body member is adapted to force a cam thereon into pushing contact with a flooring board supported by the joist.

Abstract: Apparatus and method for contact printing which comprises moving a photographic image-bearing web and a photosensitive web in close contact, and at substantially uniform speed past an exposure position in which the photosensitive web is exposed to light that passes through the transparency web. A vapor generator is provided with its output connected to a nozzle which injects vapors at the nip formed by the two intersecting webs in advance of the exposure position such that a micro-thin layer of condensation is provided between the webs so that intimate contact is established between the webs at the time they are brought together in a film gate at the exposure position.

Abstract: The specification discloses a solid transparent soap employing a greater amount of sodium soap than prior artisans have ever been able to get into a transparent bar without plodding, milling or refining. In excess of 25% sodium tallow soap to as much as 55% sodium soap, based mainly on tallow, is mixed with 10% to 40% anionic or amphoteric surfactant, combinations and/or complexes thereof, and 65% to 15% of a two or six carbon dihydric alcohol. The resulting soap composition is transparent in that one can read 14 point type through a 1/4 inch bar and can be made by simple mixing, without plodding, milling or refining.
