Abstract: A liquid chemical dispenser for an irrigation system comprises a removable supply container for the chemical which, in a first embodiment, comprises a valve for preventing spillage of the chemical during attachment of the container to the dispenser. This feature allows the container to be mounted in an inverted position on the dispenser without loss of its contents. In a second embodiment, the chemical container comprises a membrane which is pierced by a dip tube when the container is attached to the dispenser. A section of the dip tube produces an annular vent passage in the membrane around the dip tube to provide vacuum relief. The configuration of the containers substantially reduces the chance of inadvertent contact with the contents and the simple design permits the containers to be disposable.

Title: Method and apparatus for manufacturing objects having optimized responsecharacteristics
Inventor: ST VILLE JAMES A
IPC: A61F2/36
Filed: 1996-02-14
Abstract: A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix [k] is then calculated based on the relationship {f}=[k] {x}. Material property coefficients are then extracted from the material property matrix [k] for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.

Abstract: Disclosed herein are chimeric antigens, comprising an hepatitis C virus (HCV) antigen and a Fc fragment of an immunoglobulin for eliciting an immune response against said antigen. The immune response is enhanced by presenting the host immune system with an immune response domain (HCV antigen from HCV  core, envelope, or non-structural protein fragments) and a target binding domain (an Fc fragment). By virtue of the target binding domain, antigen presenting cells internalize and process the chimeric antigens for antigen presentation, thereby eliciting both a humoral and cellular immune response.
