Abstract:
A dewaxed oil having a tendency to form a haze at ambient or sub-ambient temperatures is contacted with a solid adsorbent to remove at least a portion of the haze precursors, thereby reducing the haze-forming tendency of the dewaxed oil.
Abstract:
The present application is directed to a system for collecting surface material in marine environments, comprising (1) one or more arm members extendable from an operation platform; (2) at least one sprayer releasably attachable to a distal end of at least one arm member; (3) at least one skimmer releasably attachable to a distal end of at least one arm member, the skimmer being operationally configured to collect material from a water surface; and (4) a fluid delivery means in fluid communication with the sprayer, the sprayer being operationally configured for linear discharge of fluid to a target, the direction of fluid discharge being adjustable in relation to the location of the operation platform.
Abstract:
A micromechanical device may include one or more piezoresistive elements whose electrical resistance changes in response to externally or internally induced strain. The present invention leverages the piezoresistive properties of such devices to sense the positional state of the device. A sensing circuit may be integrated into the device that senses an electrical resistance of at least a portion of the micromechanical device and provides information regarding the positional state of the micromechanical device. The micromechanical device may be a compliant device that includes relatively flexible members such as mechanical beams or ribbons. The positional states may be continuous positional states (such as the position of an actuator) or discreet positional states (such as the positional state of a bistable memory device). In certain embodiments, the micromechanical device is a threshold detector that latches to a particular stable configuration when an applied force exceeds a selected value.
