摘要:
Disclosed herein are aspects and embodiments of an apparatus for securing hollow fiber filtration membranes in a filtration module. In one example, the apparatus comprises a restraining structure engaging elongate portions of the plurality of hollow porous membrane fibers and an anchor formation engaging the plurality of hollow porous membrane fibers and positioned closer to eye portions of the plurality of hollow porous membrane fibers than at least a portion of the restraining structure. Neither the anchor formation nor the restraining structure sealingly engage open ends of the plurality of hollow porous membrane fibers.
摘要:
A membrane module (3) comprising a plurality of porous hollow membranes (8). The membranes (8) extend between and are fixed at each end in a header (5, 6). One header (6) has one or more of openings (12) formed therein. The openings (12) are in fluid communication with a source of gas and/or liquid (13, 14, 15). The other of the headers (5) is sealingly connected to and in fluid communication with a head-piece (9). The head-piece (9) is adapted to couple to an associated head-piece of a further module to form a rack of modules (17). A potting head (6) for use in mounting porous hollow membranes (8) is also disclosed comprising a preformed potting element (29). The potting element (29) includes one or more cavities (30) for receiving curate potting material which, in use, supports said membranes (8).

This invention relates to an apparatus and a method that reduces a moisture content of an agricultural product, particularly by using moisture sensors and/or temperature sensors. The apparatus includes at least one moisture sensor, optionally at least one temperature sensor, a controller, a flow regulator and/or a dryer. The method includes obtaining a moisture content and a temperature to calculate a product flowrate and optionally an energy input. A product flowrate signal is used to vary the flow regulator and an energy input signal is used to vary the energy regulator.

A membrane filtration manifold for connecting a filter submodule including one or more elongate bundles of semipermeable polymeric fibers is provided. The manifold includes a housing and connecting collar connected with said housing. The collar is adapted to receive and locate the submodule, where the submodule has a connecting sleeve with a locking formation. The submodule can be secured at one end to the collar by a clip adapted to engage both the collar and the locking formation to prevent axial withdrawal of the submodule from the collar. Also disclosed is a membrane filtration apparatus including a filter submodule including one or more elongate bundles of semipermeable polymeric fibers. The apparatus further includes a membrane filtration manifold removably connected at one end of said filter submodule and a basepiece removably connected to the other end of said filter submodule.
摘要:
A system and method are disclosed for the treatment of liquid runoff, such as rainfall, irrigation, and waste or produced water, utilizing aboveground, modular, permeable barriers containing reactive media that can immobilize particular solutes of concern, removing them from the liquid runoff. The modular design allows construction of a relatively-uniform barrier, or media volume, that is self-supporting and easily assembled, maintained, modified, and augmented. A permeable reactive barrier constructed according to the present invention provides significant contact between the reactive media and the solutes of concern while allowing the runoff stream to flow through the structure relatively unimpeded.

Modular assembly equipment including portable machinery for performing the assembly and a controlling device for controlling the portable machinery is disclosed.
摘要:
A foamed closure for a container, wherein the closure consists essentially of (a) a major proportion of at least one material selected from the group consisting of polyethylene and copolymers of ethylene; and (b) a minor proportion of at least one resilient compound. The resilient compound is preferably selected from the group consisting of polyethylene, metallocene catalyzed polyolefins, ethylene vinyl acetate copolymers, styrene-butadiene-styrene copolymers or styrene-ethylene-butylene-styrene copolymers.
摘要:
The present invention is directed to a system and method for laying masonry blocks in multiple block units. The system comprises a mortar injection device, a block hoist apparatus and a mortar applying apparatus, The mortar injection device includes a mortar feed, mortar dispensing chutes and a block tamper. The mortar dispensing chutes are positioned to inject mortar into gaps between adjacent blocks in the multiple block unit, to create a mortar joint between each block. The block tamper comprises a vibratory roller and/or a series of vibrating pistons attached to the mortar injection device, and facilitates substantially uniform settling of the mortar in the block gaps. The block hoist apparatus includes a mechanical hoist, a hoist transmission member, a weight distribution beam, gripping arms pivotally attached to the weight distribution beam, major gripping members associated with each gripping arm and mounted on a gripper mounting bar, at least one minor gripping member also mounted on the gripper mounting bar and digitally spaced from a corresponding major gripping member. At least a portion of each of the major and minor gripping members are insertable into different blocks of a multiple block unit and cooperate, upon lifting of the weight distribution beam by the mechanical hoist, to exert a clamping force along an interior portion of the blocks to retain the blocks in alignment for raising and lowering of the multiple block unit. The mortar applying device includes a mortar applicator, a housing for the mortar applicator, a housing guide and means for controlling the dispensing of mortar onto the top surface of a row of blocks, while substantially limiting application of mortar into the inner cavities of the blocks.
