摘要:
A method for testing a biological sample wherein the sample is divided into a plurality of sample portions, is fed to a sensor arrangement in a first conveying direction and is carried away in a second conveying direction which is opposite to the first conveying direction, and/or a sensor cover is lowered onto a sensor apparatus multiple times. Furthermore, a cartridge for testing a biological sample wherein different fluidic circuits can be formed by actuating valves in the cartridge, and the sample or another fluid can be conveyed in the fluidic circuits by means of a pump apparatus.

The invention provides a self supporting isobaric structure for electrolyte aeration in an electrodeposition cell for electrolytic refining or winning of non-ferrous metals, and a method of fabrication thereof. The structure is constructed using thermoplastic material pipes the external surface of which is wrapped in a thermosetting polymer composite material and one or more successive wrapped layers of fiber glass mats, thus forming a structural monoblock. The pipes are arranged in a reticular layout having a generally rectangular frame that follows the contour of the cell, transverse structural elements that connect the longer sides of the frame and tubular elements connecting the shorter sides of the rectangular frame. The tubular element provide a means for gas diffusion and aeration in the cell. Furthermore, the invention provides pipe couplings that allow shorter elements to be connected together in order to achieve the reticular configuration.

Rapid evacuation and deployment of dry materials is achieved by the dual structure of this device and the method of using it to fill and empty vacuum reloading tanks automatically. This permits materials such a bentonite, barite or cement to be handled easily and without dust on a rig floor and mixed appropriately as needed for well control and completion operations. Dry bulk material is offloaded from an offshore supply vessel into atmospheric tanks, which provide fluidized bed systems to aerate and agitate and move material through piping into the vacuum re-loader tanks. The dual re-loader tank system allows one tank to be emptied while another fills thereby providing sufficient flexibility to expertly manage receiving, storage, transfer, filtration and control of the bulk material on various space-critical platforms, including offshore rigs and service vessels, that require the handling of dry bulk materials in an accurate and dust-free manner.

A solid-acid-catalyzed saccharification device (A) includes a catalytic reaction vessel (3) configured to contain a polysaccharide feedstock with water and a solid-acid catalyst (X2) as a liquid mixture (X3) to monosaccharify the polysaccharide using the solid-acid catalyst (X2), an agitation device (4) configured to agitate the liquid mixture (X3) in the catalytic reaction vessel (3), an oxidation-reduction electrometer (5) configured to measure the redox potential of the liquid mixture (X3) in the catalytic reaction vessel (3), and a pH meter (6) configured to measure the pH of the liquid mixture (X3) in the catalytic reaction vessel (3). According to the solid-acid-catalyzed saccharification device (A), it is possible to accurately follow the reaction state of a saccharification process of a feedstock using a solid acid catalyst.
摘要:
A gas sparger produces an intermittent flow of bubbles even if provided with a continuous gas flow. The sparger has a housing to collect a pocket of gas and a conduit to release some of the gas from the pocket when the pocket reaches a sufficient size. The housing is integrated with the potting head of a module. The conduit passes through the potting head.

摘要:
Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a fluid medium and a saccharifying agent.

An apparatus for blending and storing petroleum based fuel and vegetable based fuel is provided. The apparatus includes a blended fuel storage tank; a petroleum fuel storage tank connectable to the blended fuel storage tank; a vegetable based fuel storage tank connectable to the blended fuel storage tank; and a ganged fuel controller adapted to synchronize fuel flow ratios from the petroleum fuel storage tank and the vegetable based fuel tank to the blended fuel storage tank. In an alternate embodiment the fuel may be delivered already mixed for storage and continued blending in a mixed fuel storage tank adapted to maintaining the blended fuel mixture.
