摘要:
A method of configuring a mount or of controlling sway in an object to be mounted includes configuring isolators of the mount to put a center of elasticity of the flexible mount at a desired height relative to a base of the mount. This desired distance may be at a location of expected minimum clearance between the object to be mounted and the structure expected to surround the object to be mounted and is the center of rotation of the flexible mount. The location of the center of elasticity also may be farther from the base than a center of mass or gravity of the object to be mounted. An equation relating the location of the center of elasticity as a function of isolator material properties and of angle between the isolators and the base may be used to analytically predict the location of the center of elasticity and the center of rotation.

The present concrete crack repair device (CCRD) can be comprised of two nodules connected by an elongated strip wherein the elongated strip can be narrower than the nodules in at least one plane. Both the elongated strip and the nodules can comprise carbon fibers wherein most of the carbon fibers are located within the same plane maximizing the tensile strength of the device. Installation of the CCRD can be performed by drilling holes into the surface of the concrete on either side of the crack and cutting a slot in the surface of the concrete between the two holes, or adding the holes after the slot has been cut, wherein the slot and holes are located in a line that is roughly perpendicular to the crack. The CCRD can then be installed by placing each nodule in a hole and the elongated strip within the slot.

A method includes receiving at least one process control value from a deterministic process control environment according to an execution cycle of the deterministic process control environment. The method also includes providing the at least one process control value to a non-deterministic process according to an execution cycle of the non-deterministic process. The execution cycle of the non-deterministic process does not correspond to the execution cycle of the deterministic process control environment.

A system and method for managing the activities of a process. The system includes a first computer that uses standard control classes to manage the activities according to a standard control strategy. A second computer is used by a user to input custom data. A custom application program uses the custom data to automatically develop a customized control strategy as a custom class that operates as an inherited class of a base class of the standard classes to augment the standard control strategy with the customized control strategy in the management of the activities.

For use with a computer system having a dynamic data referencing (DDR) module, a plurality of external data references accessible via the DDR module, the computer system capable of executing a user application that operates on a plurality of generic variables, a system and method for dynamically binding the external data references to the generic variables. The system includes a DDR routine within the user application that allows creation of an alias variable for at least some of the plurality of generic variables. The alias variable is adapted to identify a given external data reference. The user application employs the alias variable at runtime to request the DDR module to bind a given generic variable to the given external data reference to allow communication of data between the user application and the external references.
摘要:
An exercise device has two side bars each comprising a longitudinal segment extending between front and rear legs. The angle and length of the front and rear legs produces an incline of the longitudinal segment. The angle of incline is variable because the front and rear legs are separately adjustable in length. Slip locks selectively lock each leg at a desired length. Cross bars connected between the side bars by quick release locks. A central longitudinal bar parallel to the side bars extends between a selected two of the cross bars and is connected thereto by quick release locks.

A riser string for a subsea well uses the outer conduit or air can members to support the weight of the riser string. The outer conduits have flanges on their ends which are bolted together. The outer conduits have ports to admit sea water, and a gas injection system to displace some of the sea water for providing buoyancy. Mounting plates are located at each end of the outer conduits. Inner conduits for conveying well and production fluids are mounted between these mounting plates. The mounting plates are intrinsically curved in vertical cross-section, such that when the conduit flanges are bolted together, the mounting plates flatten to provide a compressive force across the faces. Metal seals are located in the holes provided in the mounting plates for the inner conduits. The inner conduits are supported along their lengths by one or more lateral supports.
