Abstract: A turbine engine part or set of parts including at least first and second obstacles each having a leading edge and a trailing edge, and a platform from which the obstacles extend; wherein the platform has, between the pressure side of the first obstacle and the suction side of the second obstacle a non-axisymmetric surface defining at least one fin with a substantially triangular cross-section, each fin being associated with a leading position and a trailing position on the surface between which the fin extends, such that the leading position is upstream of each of the leading edges; the trailing position is downstream of each of the leading edges.

Abstract: Passive device for broadband acoustic acquisition (3) that can communicate with a digital processing unit (4), the device including a plurality of microphone sensors (7) that can generate an electric signal (8) that is representative of an acoustic pressure (9) received, electronics for processing and digitizing (12) electric signals being able to adapt the electric signals and transform them into digital signals (13) of acoustic pressure, transfer electronics (14) being able to communicate with a digital processing unit (4) and to make possible the transfer of the digital signals of acoustic pressure to the digital processing unit. The microphone sensors and the transfer electronics are mounted on a multifunctional rigid support element (17) that incorporates the processing and digitizing electronics.

Abstract: A vehicle wheel tire having a symmetrical five rib tread construction with adjacent tread ribs comprising the tread separated by circumferential grooves. The intermediate tread grooves have an axial width wider than an axial width of the shoulder grooves and a center rib has an axial width wider than the axial widths of the intermediate ribs and the shoulder ribs. The axial width of the center rib, intermediate ribs, and shoulder ribs are within a prescribed preferred range of a total tread axial width and the axial width of each intermediate groove is within a prescribed preferred range of total tread axial width.

Abstract: The invention provides a tire tread, the tread having at least one circumferentially extending or laterally extending main groove, the maximum radial depth of the at least one main groove defining a non-skid tread depth, the at least one main groove partially forming at least one tread element, the at least one tread element having a sipe therein, wherein the sipe has a first portion having a first and second opposed side, and a third side joining said first and second side, and said sipe further including a continuous tubular pathway bordering said first, second and third side. The invention further includes a blade for molding a tire, the blade comprising a first portion having a first and second opposed side, and a third side joining said first and second side, and said blade further including a continuous tubular pathway extending along the third side and partially extending along at least one of the first and second side.

Abstract: A vehicle tire tread includes a circumferential spaced apart array of discrete tie-bar block elements within a circumferential tread groove, each tie-bar block element having a circumferentially oriented bisecting cut dividing the tie bar into opposed tie-bar components. The opposed tie-bar components operatively flex and converge axially when present within a rolling tire footprint to close the radially outward cut segment and resume a nominal separation dimension when outside a rolling tire footprint. The bisecting cut within each tie-bar block element further forms at a radially inward end a large diameter fluid conducting channel extending through the tie-bar block element to allow the passage of fluid along the circumferential groove, unobstructed by the array of tie-bar block elements.

Abstract: A method for amperometric detection of proteins, especially haemoglobin in faeces, using an electrochemical sensor. The electrochemical sensor includes: a working electrode having an electrically conductive matrix holding a first reagent and/or a second reagent, the second reagent being an oxidizing agent, or a precursor thereof, for the first reagent; a counter electrode and optionally a reference electrode; wherein a reaction between the first reagent and the oxidizing agent is catalyzed by the protein to provide a detectable signal at the working electrode. The electrically conductive matrix is an electrically conductive carbon- or graphite-containing matrix or an electrically conductive porous matrix.

Abstract: A pneumatic tire for use on trucks, the tire comprising: a tread which includes a belt reinforcement structure, the belt structure including a pair of working belts, wherein the angle of the working belts range from about 16 degrees to about 30 degrees, wherein a low angle belt is positioned preferably between of the working belts, wherein the angle of the low angle belt is less than 5 degrees. The working belts are extensible, and preferably made of high elongation wire.
