Abstract: Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells. The lysate separates into at least two layers including a lipid-containing hydrophobic layer and an ionic liquid-containing hydrophilic layer. A salt or salt solution may be used to remove water from the ionic liquid-containing layer before the ionic liquid is reused. The used salt may also be dried and/or concentrated and reused. The method can operate at relatively low lysis, processing, and recycling temperatures, which minimizes the environmental impact of algae processing while providing reusable biofuels and other useful products.

Abstract: Methods and apparatus for processing algae are described in which a hydrophilic ionic liquid is used to lyse algae cells at lower temperatures than existing algae processing methods. A salt or salt solution is used as a separation agent and to remove water from the ionic liquid, allowing the ionic liquid to be reused. The used salt may be dried or concentrated and reused. The relatively low lysis temperatures and recycling of the ionic liquid and salt reduce the environmental impact of the algae processing while providing biofuels and other useful products.

Abstract: A one-step process for the lysis of microalgae cell walls and separation of the cellular lipids for use in biofuel production by utilizing a hydrophilic ionic liquid, 1-butyl-3-methylimidazolium. The hydrophilic ionic liquid both lyses the microalgae cell walls and forms two immiscible layers, one of which consists of the lipid contents of the lysed cells. After mixture of the hydrophilic ionic liquid with a suspension of microalgae cells, gravity causes a hydrophobic lipid phase to move to a top phase where it is removed from the mixture and purified. The hydrophilic ionic liquid is recycled to lyse new microalgae suspensions.

Abstract: A sensor and method sense and quantify microorganisms and other biological materials. The sensor and method use high device temperatures to pyrolize and/or thermolyze biological materials, then gas-phase voltammetry is used to analyze the pyrolysis or thermolysis products to detect and identify the source biological material. The sensor and method are capable of differentiating between biological agents, such as pollen, bacteria, fungi, and their spores and the state of an organism such as living, diseased, or non-living. The sensor and method may operate at temperatures sufficient to be self-cleaning and self-decontaminating or at non-elevated temperatures to detect and identify combinations of volatile metabolites to detect and identify their biological sources.

Abstract: The invention relates to use of an active ionic liquid to dissolve algae cell walls. The ionic liquid is used to, in an energy efficient manner, dissolve and/or lyse an algae cell walls, which releases algae constituents used in the creation of energy, fuel, and/or cosmetic components. The ionic liquids include ionic salts having multiple charge centers, low, very low, and ultra low melting point ionic liquids, and combinations of ionic liquids.An algae treatment system is described, which processes wet algae in a lysing reactor, separates out algae constituent products, and optionally recovers the ionic liquid in an energy efficient manner.

Abstract: A motor throttle assembly for attachment to a vehicle handle bar. The motor throttle assembly includes a cable pull with a pair of opposed outwardly extending guide posts. The cable pull is disposed within a tubular inner sleeve having a pair of longitudinal cutouts designed for receiving the guide posts therethrough. The inner sleeve is rotatably supported within an outer sleeve having a pair of helical cutouts overlaying the longitudinal cutouts and designed for receiving the guide posts. Manually rotating the outer sleeve produces cooperative action of the helical cutouts and longitudinal cutouts to apply equally balanced force to the guide posts and cause the cable pull to traverse and accelerate the motor. Bearings support the traversing movement of the guide posts and the rotational movement of the outer sleeve for a smooth action of the throttle, with minimal play.

The raising mechanism may have a crank and a rod attached to the crank. When the crank is rotated, a portion of the legs is raised or lowered. The legs of the IV pole may have a first segment and a second segment. The first and second segments are attached to one another with a hinge.
