Abstract: An improvement in and pertaining to cranes for stripping and/or handling cast metal ingots. The improvement is disclosed in the illustrative environment of a crane capable of performing both functions and operations with big-end-down ingots and molds. The improvement is embodied in a horizontally disposed component of a vertical, crane-suspended, ingot working mechanism. Said component serves as a shock absorber and dampener during a stripping operation, and serves as a resilient energy reservoir in aid of an ingot handling operation. Said component takes a horizontal drum-shaped form with centrally apertured, resilient, spring tempered steel discs disposed like the heads of a drum normal to said mechanism wherein, however, the inner peripheries of said apertures engage parts of the mechanism between which there is relative vertical motion in one direction incident to stripping the ingot from the mold, and in the opposite direction when gripping the ingot to handle it.

Abstract: A coatings application apparatus pumps liquid paint through a flexible conduit within a rotary variable displacement peristaltic pump to a conventional applicator head. Through constant speed rotating lobes peristaltic action squeezes coating liquid within the conduit through the paint applicator control handle and applicator.The control handle permits changes in the paint flow rate. Upon constriction of the conduit within the control handle, flow rate is reduced, back pressure develops with resulting tube distortion. Distortion levered forces act upon a pre-set loaded pump spring. Variation in pump displacement results. The liquid flow rate within the supply conduit is inversely proportional to the back pressure so developed. If fluid flow is completely arrested by full supply tube constriction, back pressure becomes a maximum and pump displacement becomes zero. The pump continues to operate, however, at constant R.P.M., requiring no high starting torque.

Abstract: Polymer forming reactions have been previously known comprising five and six member oxazoline ring oxazolidines and reaction products containing the basic structure with polyfunctional aromatic and aliphatic isocyanates and moisture. Five types of oxazolidines have been previously illustrated.
