Blowing agent delivery system

The invention provides a blowing agent delivery system for introducing a blowing agent into a polymeric foam processing system. The delivery system is designed to discontinuously introduce blowing agent from a continuous source into polymeric material within an extruder. The system, thus, may improve control over blowing agent delivery in discontinuous polymer processing systems such as injection molding or blow molding. In some embodiments, the blowing agent delivery system selectively directs blowing agent flow from the source to the extruder barrel, or through a bypassing passageway. In this manner, blowing agent may be continuously supplied by the source but discontinuously injected into the extruder barrel. During use, the delivery system may cause blowing agent to flow through the bypassing passageway, for example, when the screw stops plasticating polymeric material.

A method of uniformly dispersing a nano powder throughout a micron powder. Ordinary mixing or agitation does not succeed in attaining uniform dispersal: the nano powder agglomerates into microscopic masses. In one form of the invention, a charge of a micron powder, with fifty weight percent of charge of nanopowder is loaded into a ball mill. The mixture is ball milled for less than two hours, at room temperature in a dry condition, and produces a highly uniform distribution of the nano powder throughout the micron powder.

Adjustable tension prosthetic ankle rotatory device for lower limb apparatus

A transtibial patellar tendon bearing (PTB) prosthesis for below the knee amputees is disclosed. The prosthesis includes a socket, and a foot prosthesis attached to a modular shank component using a foot rotator device. Using the rotator device, the foot component of the prosthesis may be smoothly and axially rotated internally or externally ±150° with respect to the shank component about the axis of the shank component. The wide range of axial rotation enables a more even load distribution on the whole lower limb of an amputee and enables an amputee to comfortably assume a wide range of biomechanical positions, such as sitting or kneeling. A recoil spring, having a selectable tension, is positioned within the rotatable component and selectively limits and retains the relative rotation of the upper portion and the lower portions. A locking mechanism selectively prevents rotation when the foot component is engaged.

Antigen detection system and methods of use

A system and method for testing for the presence of antigens in food stuffs permits a user to test food products for the presence of antigens for a given food allergy that the user may have. The system comprises two main components, a base station and a test well. The user places a sample of food into the test well. A macerator homogenizes the food in the test well. Antibodies to a particular antigen are bound to an antigen detector in the test well. The base station includes a cartridge dock which powers the macerator and the antigen detector. Antigen-antibody binding provides a change detectable by the detector, which signals the base station of the presence of a threshold degree of antigen-antibody binding and alerts the user of the presence of the antigen, such as by a visual or audible indicator.
