Abstract: A diaphragm actuator for a fluid process control device comprises a housing, a diaphragm, a stem, and a plate assembly. The plate assembly includes a concave plate and a convex plate, each having inner and outer radial portions. The outer radial portions compressingly engage and retain the diaphragm. The inner radial portions are compressed together onto the stem between a shoulder of the stem and a nut threaded onto the stem. Accordingly, the concave plate forcibly engages and provides a fluid-tight seal directly with the shoulder of the stem without requiring an o-ring or any other additional sealing component. Moreover, the concave and convex plates are structurally equivalent such that the actuator may easily be switched between a biased-open configuration and a biased-closed configuration.

Abstract: An insulated container includes a bottom and four walls connected to the bottom; a top which fits on the four walls; a portion of the top is pivotally mounted so as to be opened to provide access to the insulated container through a first opening; a portion of one of the four walls is pivotally mounted so as to be opened to provide access to the insulated container through a second opening; wherein the first and second openings are contiguous to provide a combined access area to the container that extends across both the top and the one of the four walls.

Abstract: A container includes a rigid insulated body-portion that defines a first enclosed space, a base lid adapted to be reattachably fastened to an edge of the sides that is proximal to the opening, thereby covering the opening so as to at least substantially prevent fluid communication between the first enclosed space and the area outside the container, a contents-container, a contents-container lid that is adapted to be reattachably fastened to edges of the contents container that are proximal to the opening of the contents container, thereby substantially preventing fluid communication between the second enclosed space of the contents container and the space outside the contents container, the first enclosed space including an interior portion adapted to receive the contents container and a coolant portion adapted to receive at least one coolant container.

Abstract: The present invention provides a novel cabinet cooler. The cabinet cooler has an open housing defined by a lower wall, a rear wall, opposite side walls, and a top wall. The lower wall has a plurality of wheels positioned on a bottom thereof so that the cabinet cooler can be easily moved. The lower wall also has a pair of slots therethrough having flexible seals therein such that a wheeled rack can be rolled into the opening of the housing. A door attached to one of the side walls can close the housing once the rack is wheeled into the housing. A plurality of fans pull air over dry ice cell(s) to cool the air within the housing and force the cooled air over the rack, which can hold a plurality of trays capable of holding food.
