Abstract: Technologies are generally described for perimeter seated knife gate valve. Perimeter and transverse seals may be formed together as a single-piece or as two separate pieces. Wire-reinforced and with a rectangular cross section, the perimeter seal (portion) may fit into a corresponding groove in the single-piece body of the valve. Transverse seal (portion) may include two channels formed as side grooves or tubular channels to accept packing material, which energize the seal and are isolated from the fluid stream. In the two-piece version, a bottom groove of the transverse seal may be used to interlock both pieces. The shape and structure of the seal may allow single-piece valve body.

Abstract: A method and system for clinical order entry and decision support are provided. The system and method allow physicians to input orders directly in clinical shorthand. The system presents high-probability choices for order action, determination of clinical context and possible problem solutions. The choices reflect current medical research, patient-specific information and standard practices of other physicians and/or administrators. Selections or edits to the presented choices can be entered quickly and easily, thereby allowing automated generation of complete orders needed to carry out the decisions made. In this way, medical decisions can be made and executed in a fast, efficient and standardized manner.
