Abstract: In a system for dispensing a cryogenic fluid, a bulk tank is configured to contain a supply of a cryogenic liquid. A sump is configured to receive cryogenic liquid from the bulk tank. A first positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A second positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A vaporizing heat exchanger is configured to receive and vaporize cryogenic liquid pumped from the first pump and/or the second pump.

Abstract: An electric motor assembly that eliminates external component-to-component assembly seams between coupled packaging hardware that would inhibit the creation and maintenance of, for example, IP 66 and IP 67 seals while utilizing inexpensive existing motor shaft rear bearing supports and also creating additional internal electronic packaging space. The disclosure provides an assembly with a continuous (e.g., no interruptions or seams) surface area to support IP sealing of the entire packaging-to-package interface between a primary motor frame (e.g., housing) and externally attached secondary/ancillary electronic hardware.

Abstract: An electronics drive module is connected to the flange of a drive motor assembly. The module includes: a metal frame including a peripheral wall; and a metal floor. A power supply PCBA is located adjacent the upper surface of the metal floor, and a switching chip assembly is located adjacent the lower surface of the floor. The base plate of the switching chip assembly conducts heat into the floor and conducts heat into the mounting flange. An environmental seal is located between the lower edge of the frame and the sealing surface of the mounting flange and extending coextensively with the lower edge of the peripheral wall such that a sealing zone is defined within the peripheral wall of the frame and the first and second thermal interfaces are located within the sealing zone.
