Abstract: A rowing shell for recreational and/or competitive use on flat or rough water. The shell includes a sealed and waterproof hull and attachments. The hull and attachments are sleek and streamlined in design, and are formed and contoured so as to minimize water and wind resistance. The hull includes a slightly upturned bow, a flat mounting surface on which a winged outrigger assembly is removably attached to provide support for oarlocks and a substantially flat deck in the vicinity of a rower's seating area. This allows water entering the craft to exit without impeding efficient operation. The winged outrigger assembly is mounted to the hull at the bow side of the rower's seating position. The forward portion of the outrigger assembly is tapered to blend with, and conform substantially to, the fore portion contours of the hull and consist of two arcuately shaped oar outrigger arms integrally formed with the body of the outrigger assembly.

Abstract: An integrated method that comprises a hydrocarbon thermal cracking operation to form at least one olefin product, coupled with dimerization and metathesis operations, the dimerization operation forming additional feed material for the metathesis operation, and the metathesis operation forming additional amounts of olefin product.

Abstract: A method for thermally cracking a hydrocarbonaceous feed material using a combustion fuel fired furnace wherein at least part of the combustion fuel employed in the furnace is syngas.

Abstract: An optical camera three-dimensional coordinate measuring system for use with objects to be measured is described. The system may include a compact, easily moveable, and rotatable, target of known dimensions comprising a spherical surface to be placed in contact with the object to be measured at different points along the object to be measured thereby eliminating the necessity of using a larger extended probe contact tip extending from the target to the object to be measured. At least one or more light emitting source may be located in a known position in the target such as the center of the spherical surface for example. At least two cameras located at different and known coordinate locations for receiving light from the light emitting source from different optical perspectives may be included. The position in three dimensional coordinates of the object to be measured is computed from the images taken by the cameras.

Abstract: The disclosure relates to a device for detecting the presence of a chemical contaminant. The device comprising a resilient indicator element which is biased into a first position and is anchored in the first position by means of a failure element. The failure element is made of a material which fails in the presence of a chemical to be detected, thereby releasing the indicator element from its first position and allowing it to move under its own resilience into a second position in order to provide an indication of the presence of the contaminant.

Abstract: A laser device and method capable of one or more dimensional absolute distance measurements and/or surface scanning and/or coordinate measurements of a moving external retroreflector or other moving target surfaces without using an incremental interferometer.

Abstract: A method for forming propylene wherein ethylene is employed as a primary feed material in a combination of steps comprising dehydration, skeletal isomerization, and metathesis to form a versatile product mix that can contain one or more of propylene, gasoline, MTBE, and propylene oxide.

Abstract: Embodiments may comprise methods, apparatuses, systems, and one or more computer-readable media having computer-readable instructions thereon for adjusting a laser retroreflector to compensate for passing laser light through a window of the retroreflector comprising: determining an adjustment factor to compensate for propagation errors due to passing laser light through the window of the retroreflector; and adjusting a location of a reflection point of the retroreflector to minimize the propagation errors based on the adjustment factor.

Abstract: An apparatus and method for compensating a coordinate measurement machine is provided, which may be a laser-based coordinate measurement machine, laser tracker, or other coordinate measurement device. In one exemplary method, such compensation comprises self-compensation of payload parameters by means of embedded tracker targets. In another exemplary embodiment, such compensation comprises self-compensation of payload, azimuth-post, axis, or R0 parameters by means of embedded temperature sensors.

Abstract: A cotton cultivar, designated DP 393, is disclosed. The invention relates to the seeds of cotton cultivar DP 393, to the plants of cotton DP 393 and to methods for producing a cotton plant produced by crossing the cultivar DP 393 with itself or another cotton variety. The invention further relates to hybrid cotton seeds and plants produced by crossing the cultivar DP 393 with another cotton cultivar.

Abstract: The present invention is directed to systems and methods for recording, storing and playing back audio and video works. In one embodiment, a method of presenting a variable work, such as an audio track, to a user includes presenting a first version of the work to the user. The first version has a trigger point therein. The method includes presenting a second version of the work to the user if the first version trigger point is reached during the presentation of the first version. If the first version trigger point is not reached, the first version is re-presented. In this manner, the use of a trigger point within the work can help determine whether the user should be presented with the same work again, or a different version of the work, upon subsequent views or listenings of the work.

Abstract: A method of testing the pressure integrity of a tank containing hydrocarbon in liquid and gaseous phase and its associated pipework and valves, the tank having an inlet for the supply of liquid hydrocarbon to the tank, a first outlet for the removal of gaseous hydrocarbon from the tank, and a second outlet for the removal of liquid hydrocarbon from the tank; the method comprising the steps of closing in the inlet and first outlet and monitoring the pressure within the tank during normal operation of the tank as liquid hydrocarbon is removed from the second outlet.

Abstract: A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are disproportionated with ethylene to form a propylene product, while the isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene.

Abstract: A novel cotton cultivar, designated 00W12, is disclosed. The invention relates to the seeds of cotton cultivar 00W12, to the plants of cotton 00W12 and to methods for producing a cotton plant produced by crossing the cultivar 00W12 with itself or another cotton variety. The invention further relates to hybrid cotton seeds and plants produced by crossing the cultivar 00W12 with another cotton cultivar.

Abstract: A retractable awning for attachment to a structure, such as the side of a recreational vehicle, is provided. The awning includes a shade adapted to be moved from a furled position in which the awning is secured adjacent to the vehicle to an unfurled position in which the shade provides protection from sun and rain. The awning has an upper rafter bar and a lower upright support and a locking structure for locking the rafter bar in an extended position. This locking structure can be remotely released through the use of a release arm. The awning also includes a locking structure for locking the rafter bar to the upright support. This locking structure includes a locking pin located on the rafter bar and a locking keeper slidably mounted on the upright. The upright comprises a first channel member slidably mounted within a second channel member through the use of a slider structure. The slider structure comprises a low friction surface, such as an ultra-high molecular weight polyethylene material.
