Abstract:
A method of removing at least one polar component from a fluid stream. The method comprises providing a fluid stream comprising at least one nonpolar component and at least one polar component. The fluid stream is contacted with a supercritical solvent to remove the at least one polar component. The at least one nonpolar component may be a fat or oil and the at least one polar component may be water, dirt, detergents, or mixtures thereof. The supercritical solvent may decrease solubility of the at least one polar component in the fluid stream. The supercritical solvent may function as a solvent or as a gas antisolvent. The supercritical solvent may dissolve the nonpolar components of the fluid stream, such as fats or oils, while the polar components may be substantially insoluble. Alternatively, the supercritical solvent may be used to increase the nonpolarity of the fluid stream.
Abstract:
A damper including a valve movable between an open position and a closed position to selectively alter the compression damping rate of the shock absorber. The valve may be responsive to a vertical acceleration sensor.
Abstract:
A self-testing transceiver having an on-chip power detection capability is provided. The self-testing transceiver can include a semiconductor substrate and a transmitter having a high-power amplifier disposed on the substrate. The self-testing transceiver also can include a receiver disposed on the substrate for selectively coupling to an antenna. The self-testing transceiver can further include at least one power detector disposed on the semiconductor substrate for determining a power such as an RMS and/or peak-power of a signal at an internal node of the self-testing transceiver. Additionally, the self-testing transceiver can include a loopback circuit disposed on the substrate.
Abstract:
A system and method are provided for monitoring performance capacity of a piezoelectric material that may form part of an actuator or sensor device. A switch is used to selectively electrically couple an inductor to the piezoelectric material to form an inductor-capacitor circuit. Resonance is induced in the inductor-capacitor circuit when the switch is operated to create the circuit. The resonance of the inductor-capacitor circuit is monitored with the frequency of the resonance being indicative of performance capacity of the device's piezoelectric material.
Abstract:
The present invention relates generally to a printed film innersole (PFI) and a process for making the same. The present invention provides to a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.
Abstract:
The present invention describes an apparatus and method for timing manual dexterity and hand-eye coordination competitions. Specifically, the present invention relates to an apparatus and method for timing cup stacking competitions. The apparatus of the present invention includes a mat which may incorporate a timer and the cups which are to be stacked on the mat. One embodiment of the present invention includes a multi-pieced timing mechanism which may be selectively interconnected to a mat. Further, a plurality of these timing mechanisms may be used remotely from the mat or with the mat such that a plurality of players may be used in individual mats.
Abstract:
Metal values including those of cobalt, vanadium, aluminum, molybdenum and tungsten are recovered from spent petroleum refining catalyst by acid leaching the metal values except those of molybdenum or tungsten, separating the resulting solution from the leach residue and selectively recovering the cobalt, vanadium and aluminum values from the solution and recovering the molybdenum and tungsten values from the leach residue.
Abstract:
A design pre-cut shingle design kit to allow a craftsman, as well as a homeowner, to install a custom designed shingle to their home and a method of installing a design pre-cut shingle without the help of a skilled craftsman or carpenter. A precision ramping apparatus, system and accompanying methods allow the user to place an image on a wall.
