摘要： A grease filter assembly traps more than 90% of grease from cooking activities entrained in air, and may be used in commercial range hoods. An exemplary grease filter assembly comprises a housing, an intake baffle assembly, and an exhaust trap baffle assembly. The housing is configured to house and support the intake baffle assembly and exhaust trap baffle assembly to form a single grease filter assembly. The intake baffle assembly includes air-splitting and air-redirecting baffles configured to work in tandem as a first stage. The exhaust trap baffle assembly includes a diverter array and a spacer array that forms a second stage. Exhaust air is thus directed through a tightly-defined serpentine-shaped region in the first stage and around the air-diverting baffle array in the second stage to cause increases in air stream speeds, turbulence and/or resulting pressure drops that greatly increase removal of grease from exhaust air.

摘要： This disclosure is directed to devices and fluid delivery systems for separating a gas from a fluid. The device includes a filter and a body. The body defines an interior and the filter is within the interior and segments the interior into a first chamber and a second chamber. The device includes an inlet for communicating the fluid into the first chamber; a first outlet for communicating the fluid out of the first chamber; and a second outlet for communicating the gas out of the second chamber. The filter is impermeable to liquid and isolates the second chamber from liquid. The filter is permeable to gas and permits the gas to flow from the first chamber to the second chamber to separate the gas from the liquid of the fluid.

摘要： The invention relates to a method of fluid circulation in a setup for implementing a multi-step chemical process, comprising:

supplying (102), through a first fluidic circulation system (10a) of the setup and a second fluidic circulation system (10b) of the setup (5) configured in a first supply setting, reagents (R1; R2) for performing a first step of the multi-step chemical process, to a fluidic interaction structure (25; 30) of the setup,
collecting (104), in an intermediate product container (37a, 37b) of the setup, a product (R4) obtained from the interaction between the reagents within the fluidic interaction structure (25, 30) during the first step of the multi-step chemical process, and
supplying (106), through the first fluidic circulation system (10a) and the second fluidic circulation system (10b) configured in a second supply setting different from the first supply setting, reagents for performing a second step of the multi-step chemical process, to the fluidic interaction structure (25; 30), and

wherein the reagents for performing the second step include the product from the first step collected in the intermediate product container (37a, 37b) or a product obtained from the interaction between said collected product and another reagent within another fluidic interaction structure (30).

摘要： The spin column of the present invention is used for filtering and extracting biological molecules, such as nucleic acids and proteins. When the spin column is used, it is placed inside a collection tube, which is then placed in a centrifuge slot and the centrifuge is activated. The internal volume of the spin column of the present invention is larger than that of a conventional spin column, allowing it to accommodate a larger amount of specimens. Additionally, the filter membrane positioned inside the spin column of the present invention is smaller than that of conventional spin columns. The amount of washing solution required to wash the biological molecules from the filter membrane is proportional to the size of the filter membrane. Therefore, less washing solution is required in the present invention. Since the spin column of the present invention can accommodate a larger amount of specimen, the number of biomolecules contained in the specimen is also larger. Since less washing solution is required to dissolve and recover the biomolecules from the filter membrane, the concentration of collected biological molecules in the washing solution is higher.

摘要： Extraction Apparatus (2) for extraction of a biomass comprises an extraction vessel (4) for containing a biomass. Electrical heating tape (6) is provided around the vessel (4) for maintaining the temperature of the wall of vessel (4). Upstream of vessel (4) is a solvent recycling vessel (8) which is fitted with a cooling coil (10) which communicates with an external refrigeration unit (12). Operation of unit (12) is arranged to cool (and thereby liquefy) solvent in the vessel (8). A solvent pump (22) is arranged to pump liquid between vessel (8) and vessel (4) via an electrically powered heat exchanger (24). The heat exchanger (24) is arranged to increase the temperature of solvent flowing through it very rapidly which allows the temperature of solvent introduced into extraction vessel (4) to be very rapidly changed in a step-wise manner.

摘要： A cold trap is designed to receive an incoming gas mixture and selectively deposit a chemical species on internal walls of the cold trap and exhausting undesired contaminant species from the cold trap. The cold trap includes a thermal control system designed to maintain a deposition temperature on the internal walls to achieve freeze distillation of the chemical species. The cold trap also includes an inlet and/or outlet configured to maintain a pressure in the cold trap to achieve selective deposition of the chemical species into a solid phase without condensing or depositing other chemical species. The thermal control system maintains isothermal conditions on the internal walls while rejecting heat generated in the cold trap to a cold environment outside of the cold trap. In some implementations, the selectively deposited chemical species is water and the cold environment is a lunar environment.
