Abstract: A self-propelled concrete finishing trowel has an improved power steering control system that steers the machine by tilting the driven shaft(s) of the rotor assembly or assemblies of the machine without requiring the imposition of fatiguing actuating forces by the machine's operator. The steering control system includes at least one electric actuator, such as a ball screw actuator, coupled to each rotor assembly of the machine and controlled by an operator--manipulated controller. The controller preferably includes at least one, and possibly two, joysticks that can be manipulated by the operator to steer the machine in the direction of joystick motion and preferably at a speed that is proportional to the magnitude of joystick movement. In the typical case in which the machine is steered by pivoting a gearbox of at least one rotor assembly about two axes, a separate actuator is provided for each axis of gearbox pivoting. The resultant machine is easy to operate, lightweight, and exhibits little risk of high-pressure fluid spills.

Title: Sensor array suitable for long term placement inside wellbore casing
Inventor: ROBBINS CARL A
IPC: E21B47/12
Filed: 2001-05-18
Granted: 2008-04-29
Abstract: A system based on a series of data accumulation hubs, connected together by high speed communication backbone for routing a limited number of data and power cables is suggested. Each hub is connected to arrays of sensor pods which contain the actual sensor elements and minimal, if any, interface electronics. Preferably, as many as 20 sensor pods can be connected to each single hub element wherein a system including five hub elements with 20 sensor pods each would comprise a 100 element array. The data from the individual sensors are accumulated in the hubs, buffered, and conditioned for transmission to the surface data acquisition system through the high speed metal backbone comprising multiple paths of transmission for redundancy in the event of failure. Provisions are made within each of the hubs so that if a hydrostatic leak were to occur, the fault can be isolated and the remainder of the system will function as designed. A power delivery network is also preferably encased within the backbone along with the high speed data link.

Title: Method for detecting stress and strain
Inventor: LAM DUHANE
IPC: G01B11/16
Filed: 2001-05-22
Granted: 2003-03-18
Abstract: A method of detecting stress and strain using a powder coat finish and photoelastic techniques. A part is provided with a photoelastic layer comprising a non-opaque powder coat finish that becomes optically anisotropic when stressed. Photoelastic techniques are used to detect and measure stress and strain in the part. Fringe patterns appear in the photoelastic layer indicating the locations and magnitudes of the stress and strain when the part is illuminated with polarized light and viewed through a polarizing filter. Stress and strain resulting from applied forces are detected. Structural deformation in parts that have experienced plastic deformation is also detected. Photoelastic techniques using powder coat as a photoelastic technique are less expensive and easier to apply than traditional photoelastic coatings. Applications include testing of prototypes, stress testing, inspection and monitoring of production parts, and anywhere that viewing and measuring of stress and strain are of interest.

Abstract: Methods and apparatus are provided for obtaining a secure mechanical connection and a pressure-tight seal in the overlapping area of two telescoping tubular bodies (26 and 27). The two bodies, including the overlapping area, are radially expanded to increase the inside diameter of the bodies. The expansion forces an annular seal (28) in the overlapping area into a pressure-sealing engagement between the bodies. A string of pipe assembled from joints secured to each other by telescoping, threadedly engaged expanded pin (26) and box (27) connections may be radially expanded into a surrounding well bore to provide a cased well having an internal diameter greater than the original internal diameter of the pipe string. The annular seal in the connection comprises an annular elastomeric seal ring (29) and an annular Teflon spacer ring (30). Radial expansion of the connection causes axial contraction of the groove (31), which acts with the spacer ring to expand the seal ring radially to seal the annular space created between the expanded pin (26) and box (27).

Abstract: A method and apparatus that uses control of a chaotic system to produce secu re digital chaotic communication. Controls are intermittently applied by a transmitter-encoder (12) to a chaotic system to generate the 0 and 1 bits of a digital message. A new control/no control bit stream is thereby created in which a 0 indicates that no control was applied and a 1 indicates that a control was applied. The control/no control bit stream and a prepended synchronization bit stream are transmitted, using conventional transmission technologies (14), from the transmitter-encoder to an identical receiver-decoder (16). A chaoti c system in the receiver-decoder is driven into synchrony and is subject to intermittent controls based on the control/no control bit stream, thereby causing it to generate the digital message. <IMG>
