Abstract: The invention is a caulking gun nozzle attachment for consistently applying sealant at a roofing material overlap. The attachment includes a female end for matingly engaging a caulking gun nozzle; an applicator end in communication therewith; the applicator end having a coat-hanger shaped opening defined by a convex upper surface, and a lower surface which are joined at a first edge in a spaced-apart second edge; and a vertical solid guide intermediate the first and the second edge for tracking the overlap whereby a sealant is applied at the overlap uniformly an equal distance therefrom.

Abstract: The invention pertains to a system for dispensing tacky thermoplastic material such as butyl, and the like, and includes encasing a strip of the tacky material within a thin, non-tacky thermoplastic film capable of fluxing into the material at elevated temperatures wherein the material may be wound upon a spool for transportation and handling, and the material is fed from a spool into mixing and heating apparatus, preferably in the form of an extrusion gun, for application where desired as a bead.

Abstract: An attachment device is adapted to permit a camera to be positively supported in various positions on a hand-held camera support. The attachment device includes a positioning structure which is slidably engaged by an adapter member secured to a camera. The positioning structure is mounted on a mounting structure which is secured to a hand-held camera support. The positioning structure is adjustable relative to the mounting structure between a horizontal position and a plurality of angular positions. Cooperating locking means on the mounting and positioning structures positively lock the latter in one of the horizontal or angular positions.
