Abstract: An apparatus for physical therapy is disclosed herein. The device comprises a rectangular framework portion, including two long and two short sides, in which the long and short sides each have upper surfaces, lower surfaces, and surfaces interior and exterior to the rectangle, thus defining an interior area within said rectangle. A pair of linear cross support members, each having opposite end portions are disposed about the framework in a direction perpendicular to the length dimension of the rectangle defined by the framework. Each cross support member is attached at its opposite ends to the interior surfaces of both of said long sides of said framework, and thus defines a first inner polygon portion, a second inner polygon portion, and a third inner polygon portion within the interior area of said framework.

Abstract: Multi-layer film products comprising an inner or core layer made from polyolefin polymers produced by polymerizing an .alpha.-olefin in the presence of a catalyst including: a pro-catalyst having a magnesium halide; an aluminum halide; a tetravalent titanium halide, ;an electron donor; and a silane having the formula R.sub.1 R.sub.2 Si(OR.sub.3)(OR.sub.4), wherein R.sub.1 and R.sub.2 are each an H, C.sub.1-6 alkyl, aryl, C.sub.5-12 cycloalkyl, each of which may be unsubstituted, mono- or di-substituted, and R.sub.3 and R.sub.4 are H, C.sub.1-6 alkyl, or a mono- or di-substituted C.sub.1-6 alkyl; and a co-catalyst comprising an organometallic compound, or reaction products of the pro-catalyst and the co-catalyst. The film products have excellent clarity, superior dart impact, resistance to tear and favorable sealibility characteristics.

Abstract: Provided herein is a toolbox system especially well suited for use on pickup trucks. The system provides quick and easy access to a wide variety of tools which may be contained in the toolboxes. The assemblies are modular and are readily loaded and unloaded from the bed portion of a pickup truck. An increased degree of safety and convenience is realized from use of the devices herein set forth.

Abstract: Provided herein is a process for producing bundles of fibers useful for testing of various physical properties of said bundles. The bundles include fibers attached to one another at one of their ends by various means, said means employed being selected dependent upon the type of physical testing intended for the fibers. The fibers may be keratin fibers.

Abstract: Disclosed herein are novel architectural joints for use in constructing geodesic domes. The joints disclosed are less costly to manufacture and are of increased strength over prior art joints. Through the use of the joints disclosed, construction of novel geodesic domes not found in the prior art is now possible.

Abstract: A device for containing various work implements designed for use by workers who regularly use ladders. The device holds the implements in such fashion as to be ergonomically accessible while maintaining a reduced center of gravity and hence increased stability of the ladder/device combination as a whole. Use of this device increases safety and is cost-effective enough in its construction to be readily employed by workers in various arts.

Abstract: An improved process for manufacture of expandable polymer particles is provided. The continuous process disclosed produces expandable polymer pellets in a single step while eliminating many of the dangers inherent in processes of prior art employed for the same. The polymers produced herein are of uniform size, and may be molded into various articles of manufacture using existing equipment and techniques known to those skilled in the art.

Abstract: A Handling Device for disabled patients or other heavy objects is disclosed herein. This device is totally mobile, self-contained, and is free from being attached to any permanent fixtures. Its features give increased maneuverability over prior art devices. Through use of the instant invention, patients need only to be rolled on their sides in order to be picked up and subsequently transported to various locations around the home or institution. The device is operable by the patient's themselves.
