摘要:
A process for producing fuel pellets is described. The pellets are obtainable from a particulate carbon-based material and a binder, the process comprising the following steps: admixing the material and binder, and agglomerating the so-formed mixture by tumbling. The tumbling action, such as in a rotary drum, serves to agglomerate the particles and bind the mixture into the pellets, usually with a variable size distribution. No mechanical compression force is required, and with the binders used, the process can be carried out at ambient temperature. The process provides a simple but efficient process for using waste carbon-based materials, and forming a useable fuel product, which is easily transportable and efficiently combustible. Rotating drum or pan agglomerators are relatively low cost to build, and are capable of very high tonnage throughputs. Customised products can be produced and the process enhances the economics of ash and sulphur removal in coal upgrade plants.

A display including an image-generating panel and at least one contrast-enhancing panel, a cross BEF collimator between a backlight and one of the panels, and a polarization-preserving diffuser (e.g., holographic diffuser) between the panels. Typically, the contrast panel is upstream of the image panel, and a reflective polarizer is positioned between the cross BEF collimator or and contrast panel, with the reflective polarizer oriented relative to an initial polarizer of the contrast panel. Polarization of light transmitted by the reflective polarizer matches that transmitted by the initial polarizer. Collimated light propagating from the cross BEF collimator toward the contrast-enhancing panel is given a polarization bias by the reflective polarizer, which reflects incorrectly polarized light back toward the cross BEF collimator. Alternatively, the reflective polarizer may be positioned between the cross BEF collimator and the image-generating panel when the image-generating panel is upstream of the contrast-enhancing panel.

Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool.

A display provides increased contrast and resolution via first LCD panel energized to generate an image and a second LCD panel configured to increase contrast of the image. The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images using polarization rotation and filtration. The second LCD panel may have higher resolution than the first LCD panel. A half wave plate and/or film is placed in between the first and the second panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed lights that may also include individual control of color intensities for each image or frame displayed.

A non-latex balloon has at least two outer balloon layers of a polymer such as nylon, with an inner layer of heat-sealable material. A self-sealing valve is heat-sealed to the inner surface of one of the outer layers. An inner balloon layer is placed adjacent the outer balloon layers and heat-sealed to one of them to form an enclosed pocket. Two inner balloon layers may be used to form two pockets. The seal of the pockets may be releasable by the user to put a sundry item into the pocket or the sundry item may be manufactured into the pocket. A method of manufacture of a balloon product includes the steps of: placing a valve between two outer sheets of heat-sealable material; placing an inner sheet of material between the two outer sheets; and heat-sealing the valve to the outer sheets and heat-sealing the inner sheet to an outer sheet to form a sealed balloon with a pocket between the inner sheet and the outer sheet. Two pockets may be produced by using a second inner sheet.

A microfluidic system includes a bubble valve for regulating fluid flow through a microchannel. The bubble valve includes a fluid meniscus interfacing the microchannel interior and an actuator for deflecting the membrane into the microchannel interior to regulate fluid flow. The actuator generates a gas bubble in a liquid in the microchannel when a sufficient pressure is generated on the membrane.

A two-pin liquid sample dispensing system is provided. The two-pin dispensing system comprises a pair of separately movable pins for holding a droplet of liquid therebetween. Each pin includes a tip spaced predetermined distance from the other pin to define a sample acquisition region. The pins acquire and hold a droplet of the liquid sample in the sample acquisition region formed in the space between the tips and apply the droplet to a selected sample handing system. The distance between the tips is variable to accommodate different liquid samples having varying physical properties and to vary the volume of the acquired droplet.
