Abstract: A process for producing insulating foam, wherein certain especially small inorganic minerals such as silica fume are directly integrated into bubble fluid to better mechanically strengthen bubbles formed and thus allow the formation of smaller bubbles to be reformed. The manner of reforming the bubbles is progressive and actualized by a glass bead chamber, a second stage consisting of two screened discs, separated from each other and located at the end of the glass bead chamber, and a third stage chamber presenting itself with a considerably enlarged screen area and having considerably finer meshes than the second stage.

Abstract: A process for producing insulating foam, wherein certain especially small inorganic minerals such as silica fume are directly integrated into bubble fluid to better mechanically strengthen bubbles formed and thus allow the formation of smaller bubbles to be reformed by mechanical means. In this process where these same bubbles are now in some part composed of inorganic solids. A process whereby these minerals are maintained as to their median size and dispersion within the bubble fluid by the following; rotor stator mixing and or a recirculating pump, the inclusion within exotherming calcium-chloride salt, the use of other physical exciters such as hydrogen-peroxide, and by straining out outliers of unwanted size or form.

Abstract: A nut assembly for quick adjustment of axial position relative to a threaded shaft. The nut is formed in two, physically separate sections, each having a surface portion with threads for mating engagement with the shaft. Each nut section is pivotally mounted to a bushing which surrounds the threaded shaft for movement of the nut threads into and out of engagement with the shaft threads. The sections are moved about their pivotal mountings by movement of a second bushing axially with respect to the first bushing through cooperative conical surfaces on the second bushing and on each of the nut sections.

Abstract: A nut assembly for quick adjustment of axial position relative to a threaded shaft. The nut is formed in two, physically separate sections, each having a surface portion with threads for mating engagement with the shaft. Each nut section is pivotally mounted to a bushing which surrounds the threaded shaft for movement of the nut threads into and out of engagement with the shaft threads. The sections are moved about their pivotal mountings by movement of a second bushing axially with respect to the first bushing through cooperative conical surfaces on the second bushing and on each of the nut sections. In one embodiment the second bushing is physically separate from and is moved linearly with respect to the first bushing, and in a second embodiment the first and second bushings are threadedly connected to one another with relative rotation of the two producing the relative axial movement.

Abstract: A pole assembly comprising upper and lower, hollow, telescoping rods. An externally threaded member extends from a fixed attachment at the top end of the upper rod through a nut mounted within the top end of the lower rod. The nut is divided into two half-nuts which are radially movable into and out of threaded engagement with the threaded member. A third rod, slidingly surrounding the lower rod, may be pushed up to cause a pair of tapered teeth at its upper end to engage the half-nuts and move them out of engagement with the threaded member to permit free, relative, linear, axial movement of the upper and lower rods for fast adjustment of the overall length of the assembly. A pair of coil springs in recesses in the half-nuts urge the latter into a nesting fit in a conical inner wall of a bushing, wherein the half-nuts are threadedly engaged with the threaded member to permit fine adjustments of pole length by relative rotation of the upper and lower rods.

Abstract: A wire hook to which fly material may be secured to form a lure, characterized by a crimped extremity at a point farthest from the eye. The straight spear and shank portions extend from opposite sides of the crimped extremity and the curved bow is placed in a portion of the shank between the crimped extremity and the eye. The wire configuration enhances both the appearance and performance of a lure formed therefrom by attaching fly material at various points, at least a portion of such material being attached at the crimped extremity.
