Abstract: An improved filter apparatus for a cryogenic fluid includes a filter and a support. The filter includes a mesh having an internal space and an open end. The support is associated with the mesh for maintaining a volume of the internal space above a predetermined value. In operation cryogenic fluid enters the internal space through the mesh and exits the open end thereof.

Abstract: A data center cooling system includes an air handler, a blower coupled to the air handler, and a thermal-polarization pipe coupled to the blower. The blower is configured to supply air through the thermal-polarization pipe. The system also includes at least one pressure box coupled to the thermal-polarization pipe, where the at least one pressure box is configured to house electronics. The thermal-polarization pipe includes an inner tube, an outer tube surrounding the inner tube and forming an annular cavity between the inner and outer tubes, and a thermal-polarization membrane carried by an outer surface of the inner tube.

Abstract: In one implementation, a substance removal apparatus may include a collection unit and a removal unit. The collection unit may have a structure forming a channel and an inlet to receive an exhaust from a print system. The removal unit may separate a substance from the exhaust and transfer heat from the exhaust to the print system. The removal unit may include a heat exchanger and an impaction mechanism.

Abstract: The invention relates to a waste gas system for bioreactors having a hydrophobic sterile filter, arranged at the end, and a heat exchanger which protects the sterile filter against blocking by liquid media. The gas outflow duct for discharging waste gas from a bioreactor vessel is divided in a cooling zone of the heat exchanger into a multiplicity of subducts and is extended in a heating zone of the heat exchanger to a calming zone. Due to the multiplicity of subducts, a considerably larger surface area for the removal of heat from the waste gas is available, with the result that in the case of laminar flow of the waste gas through the subducts a high effectiveness of the separation of liquids from the waste gas can be achieved.

Abstract: A method and device for the reduction of particulate forming vapors in gases, the method comprising passing the gas stream through at least one channel (12) that has a wall temperature that is lower than the condensation temperature of the vapor, the at least one channel having a hydraulic diameter (Dh) satisfying the condition that Dh<[24/(N?do)]1/2, where N is the number of nuclei present in the gas stream and do is the initial diameter of the nuclei.

Abstract: A dehumidifier is provided. The dehumidifier includes a cabinet defining an outer appearance of the dehumidifier and having an air inlet and an air outlet, and a filter assembly disposed in the cabinet and purifying air introduced through the air inlet, wherein the filter assembly comprises a filter frame and a filter case coupled to the filter frame by a hinge and being capable of pivoting frontward.

Abstract: A filter cooling construction includes a mass of filtration material held in a filter body and a cooling member extending in the mass of filtration material. A manifold communicates with the cooling member for channeling a cooling fluid to the cooling member. In another embodiment, a heat transfer construction is provided so that a temperature control fluid can flow to the heat transfer member thereby selectively heating and cooling the mass of filtration material. Once use for such constructions is in air filters.

Abstract: A biogas treatment system removes moisture and other unwanted materials from biogas originating, for example, with a landfill or anaerobic digester. Water and other unwanted materials are thus removed from landfill gas and waste water biogas, while the gas temperature is controlled to a usable level. More especially, the present invention provides for the removal of water and other unwanted ingredients of biogas with a greatly reduced energy requirement when compared to conventional technologies.

Abstract: A filter device for removing combustion gases and/or particulate matter from air comprises a cooling unit and filtering unit. The cooling unit has an inlet for receiving an air stream containing combustion gases and/or particulate matter, a cooling member for lowering the temperature of the air stream, a first outlet for discharge of a condensate, and a second outlet for discharge of the air stream containing uncondensed particulate matter. The filtering unit has an inlet for receiving the air stream containing uncondensed particulate matter from the second outlet of the cooling unit, the filtering unit having at least one filter barrier through which the air stream passes, the filter barrier being configured to catch at least a portion of the particulate matter in the air stream. The invention is also for a process for removing combustion gases and/or particulate matter from an air stream.
