Abstract: A method of servicing a wellbore in a subterranean formation comprising preparing a wellbore servicing fluid comprising a sealant material, helical fibers and a base fluid, placing the wellbore servicing fluid in the wellbore and/or subterranean formation, and allowing the wellbore servicing fluid to set therein.

Abstract: A tool holder. The tool holder is mounted to a platform (9) and comprises a plurality of legs (1) extending from respective positions on the platform (9) for connecting the platform (9) to respective positions on the workpiece. Each leg (1) has a first joint system (8a) at its platform end allowing each leg (1) to pivot relative to the platform (9). Each first joint system (8a) has an actuator arrangement (34) having a first operating mode in which the actuator arrangement (34) is configured to apply a load to move the respective leg (1), and a second operating mode in which the actuator arrangement (34) is configured to allow free movement of the respective leg (1).

Abstract: Spring set configurations that include an advantageous combination of spring geometries are disclosed. Spring elements having curved and straight sections, orientation of spring element anchor points with respect to the common radius, orientation of spring element segments with respect to a specific axis, balance of the length of spring elements about the common radius, and mass balance about the common radius can be used to mitigate unwanted out of plane motion. The spring set provides planar motion while reducing undesired out of plane motion making MEMS devices substantially insensitive to the process-induced etch angle variations of the spring elements. The spring set can be used in a MEMS gyro device which maintains the desired resonant modes and consistently low quadrature error even with process variations in manufacturing causing undesirable etch angles.

Abstract: A microstructure device has a microstructure (e.g., a circuit card assembly, a printed circuit board, etc.) defining a sensitive axis and one or more isolators configured and adapted to be compliant along the sensitive axis and to be rigid along one or more other axes.

Abstract: There is provided a method for producing purified P-glycoprotein (P-gp) in a stabilised form such that, after being reconstituted into proteoliposomes, it can be freeze dried and stored for prolonged periods of time without loss of biological activity The method comprises the steps of: i) solubilising a mixture of P-gp and other proteins obtained from cell membranes; ii) removing insoluble material by centrifugation; iii) placing the mixture of P-gp and other proteins in a purification column; and iv) running through the purification column at least one wash buffer so as to remove unwanted proteins, and then at least one elution buffer so as to recover the P-gp; wherein one or more of the buffers contains a disaccharide. Trehalose is a particularly preferred disaccharide.

Abstract: Practically ideal electrical resonance is employed to soley provide armature power, and stator power if desired, to run DC motors. A practically ideal parallel resonant tank circuit (PIPRC) is used wherein the quotient of the “tank current” divided by the “line current” (called the “quality” or “Q” of the tank) is (1) greater than one, (2) large enough to allow the percent efficiency of the electric motor to be equal to or greater than 95%, and (3) removes enough back emf or enough of the influence thereof so that criteria (1) and (2) can be realized throughout the entire operating range of the motor. Only one PIPRC is needed for a DC motor. Recontrolling and/or redesigning is done for two reasons.

Abstract: A cleaning composition for the removal of soils containing free or combined organic acids comprising (A) at least 1% by weight of a substance selected from the group consisting of (1) at least one alkali metal salt of a weak organic acid, said salt melting at elevated temperatures, preferably below about 550.degree. F and said weak organic acid constituent part being volatile and/or decomposing at said elevated temperatures on contact with said soil or (2) mixtures of salts thereof, the mixtures having melting points lower than the cleaning temperature, preferably less than 550.degree. F; and (B) up to 99% by weight of a carrier. The novel method of cleaning soils containing free or combined organic acids comprises applying the said salt or salts of weak organic acid to said soil, heating the salt(s) and soil above the melting point of the said salt(s) and then removing the residue.
