Abstract:
A device such as an aerofoil which in use is subject to fluid flow, includes an outer surface part the geometry of which is variable to affect the fluid flow, the device including a support structure which supports the outer surface part, the support structure being internal of the device and including a plurality of support members of composite material the geometry of the support structure being changeable by an actuating apparatus, between a first stable geometry and a second stable geometry to effect variation in the geometry of the outer surface part, the support members providing structure stiffness to the outer surface part.
Abstract:
A tool system is provided for aligning and plumbing a poured concrete form (e.g., a lower vertical form portion) for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a center line running vertical to the length of the tool and a two-way level system incorporated therein. The tool can be used to line up the lower vertical form portion with a layout string and plumb the lower vertical form portion square. A metering pole that can be locked in place is used to lower and raise the tool into and out of the lower vertical form portion, wherein the tool is completely rotatable about the metering pole. Once the lower vertical form portion is aligned with the tool, the earthen hole is back filled, thus holding the lower vertical form portion in place in the correct position. A hot knife system can be used in conjunction with the metering pole of the tool to cut the top of the lower vertical form portion to grade.
Abstract:
The position of a feature within an image is determined by determining an initial estimate of the feature position to within a fraction of a pixel, translating the feature by an amount equal to that fraction of a pixel, determining further estimate of the translated feature position to within a fraction of a pixel and summing the pixel fraction of the previous estimate with the further estimate of the position to arrive at a refined estimate of the feature position.
Abstract:
A computer system for creating and managing a database of communication recipients which processes queries and otherwise operates in accordance with user commands to perform telemarketing, mass mailing, direct mailing and other communication functions. The computer is programmed to create automatic salutations, to automatically generate lists of carbon copy recipients, and to export data from the database to word processing systems for merging with text. In addition, the computer is programmed to analyze new records to ensure they are not duplicates of existing records. A user is provided with options to keep one or both records, or to combine both records into a new record. The computer is programmed to retrieve records on the basis of queries using one or more defined codes which can be ANDed and ORed together in accordance with Boolean logic, among other functions.

Abstract:
An assembly for mounting various work tools, e.g., a backhoe, to a pair of parallel frame members (28) of a vehicle (20). A pair of parallel main beams (26) extend transversely across the frame members (28) and a telescoping stabilizing leg (24) extends downwardly from each end of each of the main beams (26). Four posts (48) extend from the main beams (26) for connecting the main beams (26) at spaced positions along the pair of parallel frame members (28). Each of the posts (48) is L-shaped in cross section with one flange thereof welded to the associated main beam (26) and the other flange attached to the vehicle (20) frame members (28). A pair of bearing blocks (50) are disposed on a first leg cross-beam (42) for pivotally supporting a and a pair of hydraulic cylinder-pistons (52) are attached to a main cross-beam (40) for pivoting the backhoe about the bearing blocks (50).
Abstract:
A form system is provided for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a support system, including a wire support member and an associated base foam ring having an offset center hole corresponding to the centerline of the concrete footing, which is placed at the bottom of the earthen hole. A lower vertical form system, including multiple interlocking pieces, is assembled and joined at one end to an offset disk member. The disk member of the lower vertical form system is then placed onto the base foam ring in abutting engagement. The form system is then plumbed and positioned, e.g., in relation to one or more layout strings. Once the form system is in the correct position, the earthen hole is backfilled, e.g., with dirt or other material, thus holding the properly positioned form system in place. The lower vertical form system is then cut to grade. Reinforcing assemblies, such as rebar, can then be inserted into the lower vertical form system. Concrete can then be poured into the lower vertical form system, thus forming a lower portion of the concrete column or footing. An upper vertical form system can then be used to form the upper portion of the concrete column or footing, e.g., that portion that is above grade.
