In an embodiment, the permanent magnets are formed of a rare-earth alloy. In an embodiment, the gel is capable of being heated and retaining the heat. In an embodiment, the gel is capable of being cooled and retaining the lack of heat. In an embodiment the gel is a non-toxic biodegradable gel.

Abstract: A controller for controlling a combined heat and power (CHP) system which can include one or more CHP units, can comprise a high level optimizer and one or more low level optimizers. The high level optimizer can be configured to optimize a total cost of producing heating, cooling, and electric power, by allocating total heating, cooling, and/or electric power setpoints one or more CHP unit types, based on the fuel price, CHP unit operational constraints, and/or heating, cooling, and/or electric power demand. The low level optimizer can be configured to allocate cooling, heating, and/or electric power setpoints to individual CHP units, based on the high level allocation to CHP unit types.

Abstract: A container, such as a can, has an outer surface including having a bottom surface and a top surface. The bottom surface is capable of engaging the top surface of another container for stacking the containers. A connection mechanism has a pair of complementary components carried by the outer surface of the container wherein one of the pair of complementary components is carried by the container engages the other of the pair of complementary components carried by another container for securing the containers together.

Abstract: Compounds suitable for use in providing male contraception, an assay method for identifying such compounds, and methods of providing contraception using the compounds, are provided. The compounds described herein inhibit Eppin-semenogelin binding, and inhibit forward motility of sperm in humans and other primates. The assays identify compounds which both inhibit eppin-semenogelin binding and inhibit sperm motility, and can be carried out in a high throughput manner, using labeled recombinant Eppin and semenogelin. The compounds can be used in oral or transdermal compositions to temporarily and reversibly inhibit male fertility. They can also be used in addition to, or in place of, spermicides in spermicidal compositions, such as those used in conjunction with condoms, diaphragms, and spermicidal jellies.

Abstract: A helicopter rotor blade that has a blade body and a control flap secured to the blade body. The rotor blade has a first primary mover capable of generating a first linear motion that is sufficient to generate a high amplitude, low frequency motion of the control flap; and a second primary mover capable of generating a second linear motion that is sufficient to generate a small amplitude, high frequency motion of the control flap. Further, the rotor blade has a coupling transmission for combining the first linear motion with the second linear motion that generates a cumulative linear motion; and a second transmission device that causes the cumulative linear motion to rotate the control flap.

Abstract: A self-lubricated actuator for a rotor blade flap of a helicopter having a housing; a motor having a shaft disposed in a bearing is provided. The actuator further has an output rod and a mechanism operatively associated with the motor and the output rod to transmit movement from the motor to the output rod. The housing includes a lubrication medium capable of substantially immersing the bearing, the motor shaft and the mechanism during operation.

Abstract: Methods and apparatus are provided for measuring component concentration in a liquid containing relatively large particles and relatively small particles. The invention may be utilized for measuring fat and casein concentrations in a dairy product, but is not limited to such use. A polarized light beam is directed through a scattering cell having first and second windows and containing a sample of the liquid. A normal to an exterior surface of the second window of the scattering cell is at or near Brewster's angle with respect to the light beam to reduce or eliminate reflections. A first light detector, positioned at an angle of about 5° to about 45° with respect to the light beam, detects scattered light from a first component of the liquid, such as fat particles. A second light detector, positioned at an angle of about 130° to about 160° with respect to the light beam, detects scattered light from a second component of the liquid, such as casein particles.

Abstract: A photocurable thermally transferable composition containing a multifunctional monomer that is substantially non-liquid at room temperature and a thermoplastic binder is disclosed. The composition is suitable for use in thermal transfer ribbons. After thermal transfer, the compositions are photocured to provide a durable, weatherable image on a graphic article.
