Abstract: A light with integrated light and thermal guides, and having solid state light sources such as LEDs. The light guide includes a material having a first surface and a second surface opposite the first surface and forming an interior volume. The light guide is coupled to the LEDs for receiving and distributing light from them through the first surface, and the light is transported through the light guide until the light is extracted from the first or second surface. The light guide can include alignment features such as fiducials that mate with a base. The thermal guide is contained within the interior volume and integrated with the light guide for providing thermal conduction from the LEDs for cooling the light. The thermal guide can be vented to provide for internal cross flow of air for the cooling.

Abstract: A diamond patterned tubular pleated filter element is disclosed. Also disclosed is a filter cartridge that comprises a core element having an inner diameter, two ends and apertures formed therein, a diamond patterned tubular pleated filter element having an inner and an outer diameter positioned about the core element wherein the ratio of the outer diameter to the inner diameter of the diamond patterned tubular pleated filter element is about 1.5 to about 2.5, an open end cap, for transferring fluid into or out of the core element, positioned at one end of the core, and a closed end cap, for preventing fluid from exiting therefrom, positioned at the other end of the core, the closed end cap including structure for positioning the open end cap in filtration housing. Systems and methods for manufacturing the filter cartridge and the diamond patterned tubular pleated filter media itself are also disclosed.

Abstract: Liquid-liquid extraction elements are described. A liquid-liquid extraction element includes a first layer pair and a second layer pair disposed adjacent the first layer pair forming a stack of layers. The first layer pair includes a first polymeric microporous membrane, and a first flow channel layer oriented in a first flow direction having a fluid inlet and a fluid outlet disposed on first opposing sides of the extraction element. The second layer pair includes a second polymeric microporous membrane and a second flow channel layer oriented in a second flow direction different than the first flow direction and having a fluid inlet and a fluid outlet disposed on second opposing sides of the extraction element. The first microporous membrane is disposed between the first flow channel and the second flow channel. Methods of extracting a dissolved solute from a first liquid to a second liquid are also described.

Abstract: A machine for forming filled sealed pouches from a continuously moving sealable web of material includes a first sealing station for forming a longitudinal seal along a side edge of the web, and a horizontal sealing station for forming a plurality of transverse seals in the web. The horizontal sealing station includes a pair of conveyors each carrying jaws that mate along a sealing path to form the transverse seals. A method of forming filled sealed pouches from a continuously moving sealable web of material is also described.

Abstract: An apparatus and method for isometric muscle strength testing using a chair apparatus (40) having a support frame structure (42), a seat assembly (46), a foot rest assembly (60) and load cells (100) interconnected to the support frame structure (42) for measuring the isometric force exerted by any of a plurality of muscle groups in a human subject's body. The load cells (100) are possibly positioned on six track systems; a posterior track (80a), left and right lateral tracks (80b,c) an anterior track (80d), a forward upper track (80e) and a forward lower track (80f) to enable alignment with the muscle group selected for testing.

Abstract: Disclosed are an apparatus and method for cutting paper sheets into smaller sheet sections and collating the sheet sections. The apparatus includes a table having a longitudinal section, followed by a transverse section. Chains just below the table move a sheet stack longitudinally past a first blade which cuts the stack longitudinally, after which one of the stack portions is elevated above the other and placed on top of the other to combine the portions into a second stack. A second pair of chains moves the second stack in the transverse direction past a second blade which cuts the second stack transversely. One of the stack portions formed by the second cut is elevated above, then placed on top of, the other portion to form a further reduced sized third stack, which then is moved transversely to a third cutting station at which it is cut in the transverse direction. Again, one of the portions created by the third cut is elevated above and placed on the other portion to form a final stack of sheet sections.
