Integrated porous rigid wall and flexible wall permeability test device for soils

An apparatus for measuring permeability accurately in expansive clay and non-expansive soils is provided. The apparatus includes hollow porous stone cylinders which prevent the sample from bulging and at the same time allow application of confining pressure on the soil sample enclosed in a flexible membrane, which simulates the field condition and allows for application of back pressure to aid in saturation. The apparatus also allows for accurate comparison of hydraulic characteristics of swelling clays with fluids of various dielectric and other properties. The apparatus can also be used to consolidate the sample either three dimensionally or in one direction and perform permeability tests as well as find out the consolidation characteristics of the sample.

Rotor with elastic diaphragm defining a liquid separating chamber of varying volume

A rotor for collecting and centrifuging biological fluids in a range of volumes. The rotor includes an elastic impermeable diaphragm which defines at least a portion of a variable-volume processing chamber, where the fluid is centrifuged. The rotor includes a rigid mounting member, to which the diaphragm is mounted and which is held and spun by a chuck. Preferably, this rigid mounting member includes a boundary wall which together with the elastic diaphragm defines the chamber. The boundary wall may be a substantially imperforate circular wall which extends to the periphery of the processing chamber but defining one opening, preferably near the axis of rotation, permitting a conduit or conduits to pass therethrough so as to be in fluid communication with the processing chamber. The rotor may include a separate structure for controlling the flow of liquid out of the chamber into the conduit. In a preferred embodiment, this outlet-control structure is a perforate, substantially rigid wall or plate, located within the processing chamber and mounted adjacent the rigid boundary wall. In an alternative embodiment, the outlet-control structure for controlling flow from the processing chamber to the conduit may include at least one tube or preferably a set of tubes, wherein each tube provides fluid communication between the chamber and the conduit.

Segmented, elongated, expandable, 4-season, double-walled, low-cost, rigid extruded plastic panel structures

Low-cost, semi-permanent rigid-wall modular longhouse-type, peaked-roof structures, stadium-shaped (in plan view), made of light-weight, water-proof cellular extruded plastic sheet material die cut into blanks that are easily portable, quickly field erectable and dismountable by unskilled workers for a wide variety of uses. Two semi-circular end portions are spaced apart and joined by multiple segments of straight wall and roof modules, the length depending only on the number of intermediate segments. Blanks are easily folded on site into double-walled, bolt-together, modular wall and roof panels. Only four basic panel configurations are needed to form all structural elements. Multiple modular structures may be grouped to form larger compound structures with individual ones assigned to individual persons or dedicated work space usages: disaster shelters, sleeping, gathering, storage, hygiene, medical treatment, schooling, entertainment, goods manufacture, cooking, eating, herding, etc. Double-wall modules provide inter-stitial space for cold-weather insulation and passive ventilation in hot environments.

Micro-perforated plate with resonant sound absorption structure

The invention relates to a micro-perforated plate with a resonant sound absorption structure. The micro-perforated plate with the resonant sound absorption structure is characterized by comprising a rigid wall, a micro-perforated plate and a cavity which is formed between the rigid wall and the micro-perforated plate, wherein the two ends of the rigid wall are connected with the two ends of the micro-perforated plate through a flexible or elastic material respectively. In the sound wave absorption process of the micro-perforated plate with the resonant sound absorption structure, the distancebetween the micro-perforated plate and the rigid wall can be automatically adjusted and a semi-active resonant sound absorption structure is formed in the cavity between the micro-perforated plate and the rigid wall along with the variation of sound wave frequency and the influence of vibrating air flow. Therefore, the micro-perforated plate with the resonant sound absorption structure has highersound absorption performance in a wider frequency range, the sound absorption frequency band of the micro-perforated plate with the resonant sound absorption structure is greatly expanded, and the defect of a narrower sound absorption frequency band of a sound absorber of the micro-perforated plate with a rigid structure can be overcome. The micro-perforated plate with the resonant sound absorption structure can be widely used for the sound absorber, mufflers and various sound absorption and insulation structures to treat a noise environment caused by air power noise.
