Abstract: In the present disclosure, a structural coupler is disclosed for coupling together structural members, such as trusses. The structural coupler is dimensioned such that it can be installed at an end and within an inner channel of the structural member. The structural member includes a gusset member, a face member and a reinforcing member. The face member is connected to the gusset member and the reinforcing member is connected to both the gusset member and the face member. To couple structural members together, the face member of the structural member installed at an end of a first structural member is mated with the face member of the structural member installed at an end of a second structural member. The structural couplers are then joined together using a coupling mechanism.

Abstract: A computer system comprises a memory configured to store a geometric description of an object, wherein the memory is configured to store a first set of parameters associated with a first artistic look, and wherein the memory is configured to store a second set of parameters associated with a second artistic look, and a processor coupled to the memory, wherein the processor is configured to determine a first set of rendered data in response to the first set of parameters and to the geometric description of the object, wherein the processor is configured to determine a second set of rendered data in response to the second set of parameters and to the geometric description of the object, and wherein the processor is configured to determine a visual representation for the object in response to the first set of rendered data and in response to the second set of rendered data.

Abstract: A method of transmitting data acoustically through a tubular structure, such as a drill string or production tubing in an oil or gas well, predominantly comprising a series of tubing sections (1)joined end to end by couplings (2), at least a preponderance of the tubing sections having an axial length of at least a dimension X between couplings and at least a preponderance of the couplings having an axial length of no more than a dimension x, where X is substantially greater than x. The method comprises propagating acoustic signals along the structure, between transducers (9,10) over a distance N of at least 10X, in the form of tone bursts at least predominantly comprising a selected guided wave mode (preferably the L(0, 1) mode at low frequency) with a wavelength of at least 2x, and each burst having a temporal length of substantially less than 2N/C and preferably no more than 2X/C, where C is the phase velocity of the selected mode.

Abstract: A seal segment for a turbine is provided having labyrinth teeth and a brush seal disposed along the labyrinth teeth. A plurality of the segments for a seal ring. The segments are separable from each other so that the seal can retract. Each segment has two ends, each of which abuts another segment, with those ends lying along a radius (when looking down the shaft of the turbine). The brush disposed in each segment has ends that do not lie along a radius, but fit together in a tongue and groove configuration when the seal segments come together to form a seal.
