Abstract: A method for assembling a rotor assembly and a rotor assembly are provided. The method comprises providing a rotor blade including a first sidewall, a second sidewall, where the first and second sidewalls are connected at a leading edge and a trailing edge and extend in span from a root portion to a tip portion, removing blade material from the tip portion to form a tip portion rake angle that enables the tip portion to extend obliquely between the first and second sidewalls, and coupling the rotor blade to a shaft such that during tip rubs the tip portion rake angle facilitates reducing radial loading induced to the blade during tip rubs.

Abstract: A vehicle and work attachment for the vehicle are disclosed in which the vehicle is of the type having a vehicle body, forward extending support arms, a motor-driven hydraulic fluid pump, hydraulic lines for carrying hydraulic fluid, a hydraulic fluid reservoir, and hydraulic cylinders for moving the arms with respect to the body. Controls may be provided for controlling the valves that control supply of hydraulic fluid to the hydraulic cylinders. These hydraulic valves may be mounted on the work attachment. Additionally, the work attachment may include hydraulic cylinders that are controlled by a control on the vehicle via valves mounted on the attachment.

Abstract: A waste treatment method includes the concentration of selected strains of bacteria in a selected medium in the presence of nutrients and water, under aerobic conditions. This concentrated batch is thereafter discharged for downstream applications in wastewater remediation. The present invention employs a cultivation chamber having inlet ports and a circular vent port that allows for adequate air introduction and heat release. Aeration is achieved by recirculation of the fluid medium from the top of the apparatus through a pipe that runs the length of the inner wall and is specially configured at the top to minimize cell damage. Fluid can be routed tangentially in both the clockwise and counterclockwise directions within the chamber. The conical bottom also has an orifice allowing for recirculation of the fluid medium tangentially to the sidewalls.

Abstract: A system and method for removing water from a liquid desiccant such as a glycol used to dry cooled air in order to restore the desiccant to a purity up to around 97% in a closed continuous flow process. Liquid desiccant can be sprayed into cooled air in a conditioner where it gains moisture. The wet or gained desiccant can be optionally preheated in an economizing heat exchanger and then routed into a concentrator. Desiccant pure to around 97% can be removed from the concentrator, passed through an economizing heat exchanger to provide the preheating and returned to the conditioner holding area. The concentrator can be heated by steam or other means such as natural gas to boil the wet desiccant causing mixed vapor to enter a vertical distillation column where most of the glycol condenses out on the column packing or plates and returns to the concentrator.

Abstract: A method of producing a film coated onto a substrate by dissolving a metal or metalloid containing compound having hydrolysable groups in a solvent to form a precursor solution. The precursor solution is coated onto the substrate as a continuous liquid phase. The precursor solution is then cured to produce a continuous, interconnected, nano-porous network.

Abstract: An imaging and display system provides helicopter pilots with an unobstructed display of a landing area in a brownout or whiteout condition by capturing a high resolution image of the landing area prior to obscuration. Using inertial navigation information from the aircraft or an independent system, the system transforms the image to a desired viewpoint and overlays a representation of the helicopter's current position relative to the landing area. The system thus greatly improves orientation and situational awareness, permitting safe and effective operation under zero visibility brownout conditions.

Abstract: A method of producing a silica coating by forming a silica precursor formulation that is coated on a substrate as a continuous liquid phase. The silica precursor formulation is then cured in an ammoniacal atmosphere to produce a continuous, interconnected, nano-porous silica network.

Abstract: Control of gas turbine speed and acceleration during unloaded rotation may limit stresses on components and facilitate timely operational performance. Operation of a torque converter driving a gas turbine shaft from a starter motor provides control over acceleration and speed of the gas turbine shaft. Hydraulic coupling between the input and output of the torque converter is adjusted by draining and refilling the working fluid in a body of the torque converter to control acceleration and speed of the rotor shaft during a first speed range. Vane positioning within the torque converter may be alternated between discrete speed settings to control acceleration and speed of the rotor shaft during a second speed range. A turbine control system with an acceleration schedule may provide control signals for these functions.

Abstract: An airfoil is disclosed having a concave pressure side and a convex suction side defining a chord length, and a leading edge and a trailing edge. A leading edge protective strip is adhered by a bond layer to and protectively covers the leading edge and respective predetermined portions of the pressure side and suction side of the airfoil body from the leading edge downstream towards the trailing edge. The leading edge protective strip includes a multiplicity of inwardly-facing grooves in which the bond layer is embedded. The grooves define adjacent segments of a predetermined size sufficiently small that, if detached from the vane during engine operation, impact with downstream engine components will not cause damage to the downstream engine components.

Abstract: The field of the present invention pertains to a controlled transfer biological collection device using a dry solid storage and transfer medium and a method for the collection of biological material of interest (genetic or proteinaceous material) in a form suitable for storage and/or subsequent analysis. Specifically, the present invention provides for a sampling device that controls the transfer of the biological sample to the storage medium by holding the storage medium and a moveable sample collection member having an analyte collection surface. The invention further provides for a method not only for storing a biological analyte on this collection device but also for analyzing the stored biological analyte using methods that are suited for automated analyzing systems.

A leading edge protective strip is adhered by a bond layer to and protectively covers the leading edge and respective predetermined portions of the pressure side and suction side of the airfoil body from the leading edge downstream towards the trailing edge. The predetermined portion of the suction side covered by the leading edge protective strip is less than the predetermined portion of the pressure side covered by the leading edge protective strip.

Abstract: A user annotates a shared document with text, sound, images, video, an e-mail message, graphics, screen snapshots, web site snapshots to share with others. The document and its annotations are stored in a digital object repository to which other users have access. Within the closed collaboration system, only users who are authenticated may upload digital objects, annotate digital objects and view objects and their annotations. The user sends a message to other users to invite them to view the object and its annotations and to add their own annotations. An annotated object generates an alert for all of the invited users. A remote authentication gateway authenticates users and has a repository for user metadata. Digital object repositories are separate from the authentication gateway, thus providing for disintermediation of the user metadata from the digital object data. The collaboration system may be hosted by a third party on a server computer available over the Internet that displays a web site.

An operating system includes a well tool with an actuator positioned downhole. A device for causing the actuator to operate the well tool is also positioned downhole remote from the actuator. A method of operating a well tool includes the steps of: positioning the well tool in a well, the well tool including an actuator; positioning a power source for the actuator in the well; and at a downhole position remote from the actuator, causing the actuator to operate the well tool.
