Abstract: A modular, fluorescent, indirect lighting system which may be easily mounted to most surfaces by the user, without any technical knowledge or experience, using just a screwdriver and measuring tape. The system is comprised of a family of plug-in modules, each of which contain an integral power bus (84 and 86), that provides power continuity to the adjacent module, and a gender conversion plug (42) that allows the installer to configure each module so that power is supplied only from female connectors. The system includes a power source module (110) and three sizes of illumination modules (156, 158 and 52), which house single 20, 30 or 40 watt lamps, as well as inside and outside corner modules (118 and 122) and both straight and corner adjustable-length modules (128 and 148). Modules selected from this family can be plugged together to create a cove lighting system for a room of almost any size or shape. The complete installation is powered by a neat line cord (116) plugged into a standard wall outlet.

Abstract: A compact and efficient spray cooling system is provided for cooling a heat source or a plurality of heat sources. The system uses at least one atomizer arranged in an array to deliver a fine spray across a wide distribution to impinge upon the surface to be cooled. The spray maintains a thin liquid film upon the cooled surface where heat is transfered in a phase change process. The liquid and vapor resulting from the heat transfer process is removed from the system at the edges of the heat source(s) and uses the momentum of the original spray to move the vapor and liquid to a fluid removal port. The use of the momentum of the spray to remove the liquid from the system allows the system to be gravity independent and used in transportation, avionics, and spacecraft applications where adverse gravity conditions exist. The atomizer array can be spaced closely to the heat source because the individual atomizers develop the spray in a relatively short distance.

The chill block (10) includes a channel (22) that forms a cooling groove in heat exchange relation with the controller (20). The chill block (10) receives a portion of the refrigerant being circulated in the system (12). The portion of the refrigerant received expands in the chill block (10) to a saturated vapor and extracts heat from the controller (20) as the heat of vaporization from such expansion.

Abstract: Means are provided to separate liquid particles from a flowing gas and liquid particle mixture which does not require any moving parts. A housing receives the gas and liquid particle mixture and includes a porous membrane interface which separates a higher pressure area from a lower pressure area within the housing. An elongated spiral conduit forming an area of higher pressure provides a flow path from an inlet to an outlet of the housing. The liquid particles in the flowing gas and liquid particle mixture are urged by their flow through the elongated spiral conduit into contact with the porous membrane interface. The liquid particles coat the porous membrane interface and form a film created by the surface tension of the liquid. Liquid from particles which continue to come into contact with the porous membrane interface is urged through the membrane into the lower pressure area while gas is retained in the higher pressure area. The separated liquid and cleansed gas can be removed from the housing for reuse.

Abstract: Cooling assemblies of the cooling apparatus each include an air atomizing spray nozzle located within a heated cooling chamber. An outer conduit interconnects the spray nozzle of each assembly and a source of cooling water. An inner conduit within the outer conduit interconnects the spray nozzle and a source of compressed air. Water passing through the outer conduit cools both it and the inner conduit. The outer conduit includes a flexible section that interconnects rigid sections and allows the latter to freely undergo differential expansive and contractive movement. Generally conical spray patterns produced by the spray nozzles form a circular array within the cooling chamber. Adjacent ones of the spray patterns abut each other and another nozzle spray pattern produced by a spray nozzle located generally centrally of the array and of the cooling chamber.
