Abstract: Surface modifications and improvements to piezoelectric-based sensors, such as QCMs and other piezoelectric devices, that significantly increase the sensitivity and the specificity (selectivity). These modifications can comprise mechanical and chemical changes to the surfaces of the sensors, either individually or together. For example, nanosize structures may be provided on the surface to improve sensitivity. Additionally, chemical coatings may be tethered to the surfaces, walls, or crystal to provide targeted sensitivity. Additionally, porous, layered and multiple senor arrays may be formed to enhance sensitivity and selectivity.

Abstract: The present invention is a system and method for generating speech sounds that simulate natural emotional speech. Embodiments of the invention may utilize recorded keywords. Embodiments may also combine word sound segments to form words that are not available as recorded keywords. These keywords and word sounds may be selected using a word sound dictionary used during a text analysis process. Keywords and words formed from word sounds may be formed into sentences or phrases that comprise silent spaces between certain words and word sounds.

A turbine power generator is located in fluid communication with a subsea fluid flow path of a subsea well system and the turbine power generator is operationally connected to a subsea power device.

Abstract: A pneumatic pogo stick is provided that utilizes compressed air like a spring to have a potentially higher power to weight ratio than a comparable coil spring pogo stick. The pneumatic pogo stick includes an elongate cylindrical housing which forms a cylinder. The housing is formed from a clear polycarbonate plastic. A top cap is attached to one end of the housing to form the top of an air chamber. A piston, slidable within the cylinder, forms the bottom of the air chamber. An elongate shaft is coupled to the bottom of the piston and is moveable therewith, extending from the distal end of said housing as the piston moves within the cylinder. A bottom bracket assembly is attached to the bottom of the housing and a bushing for maintaining the lateral position of the shaft relative to the housing is attached to the bottom bracket assembly. The bushing prevents the shaft from rotating relative to the housing.

Abstract: Copolymers containing acryloylmorpholine and vinylimidazole, and optionally vinylcaprolactam and/or n-vinyl pyrrolidone, have shown superior results in hydrate inhibition tests at conditions of 7° C. subcooling dosed at 1 vol % based on the water cut of the system fluids. The copolymer product has also passed high TDS (total dissolved solids) brine compatibility tests and secondary property tests including foaming and hot injection tests which make it useful as a kinetic hydrate inhibitor in gas production systems susceptible to the formation of natural gas hydrates.

Abstract: A method of operating chromatography column apparatus comprising a column tube (101) and first and second discrete end cell structures, associated with the respective ends of the column tube and positionable to close off the column tube and define therein a column space for retaining chromatography medium in use of the apparatus. The first end cell portion comprises a piston portion (106) fitting slidably in the column tube. The column tube and the second end cell structure are separated to provide an access spacing between them. The piston portion (106) of the first end cell structure is advanced through the column tube to expose it at the open second end of the column tube, for maintenance of the piston portion thus exposed. Corresponding chromatography apparatus is another aspect of the disclosure.

Abstract: A device for sorting railroad tie plates comprises hopper, singulator and chute assemblies mounted to a main frame capable of rolling movement along a railroad track. The device receives a plurality of tie plates from an upstream supply, e.g., a railroad gondola, and deposits the tie plates on the hopper assembly positioned above the singulator. Upon discharge from the hopper the tie plates are directed onto a central hub for guidance into a rotating track within the housing. The track width is selected so that the field and gage ends transverse the track upon the tie plates falling flat onto the track. Structure projects into the track to tip over the tie plates to a flat position during track rotation. Rotation of the track moves the tie plates towards a baffled opening for discharge from the opening. A chute assembly receives the tie plates and maintains the tie plate orientation for delivery to downstream devices, such as a conveyor belt.
