Granted: 2010-08-17
Abstract: To prevent an exhaust throttle valve from disturbance due to stones scattered thereto. Front side exhaust pipes and rear side exhaust pipes are connected to a catalyst chamber disposed below a crankcase. The exhaust chamber and an exhaust chamber rearward thereof are connected to each other via a rear exhaust pipe. The diameter of the rear exhaust pipe is smaller than the lateral width of each of the catalyst chamber and the exhaust chamber, so that a recessed space is externally formed so as to recede inside of the vehicle. An exhaust throttle valve is received in the space. The exhaust throttle valve is partially exposed to the outside of the rear exhaust pipe and a throttle valve is received in the rear exhaust pipe to throttle-control the passage-sectional area of the rear exhaust pipe according to the rotation number of the engine. Thus, the exhaust throttle valve can be protected from disturbance due to scattered stones.

Abstract: An ultrasonic probe performs flaw detection of a high (t/D) metal pipe. The front end portion of a transducer has at least a portion with an asymmetrically curved shape having a radius of curvature which progressively increases from one end towards the other end of the front end portion. The probe is disposed with respect to the pipe with its end having the smaller radius of curvature positioned on the side away from the direction of propagation of refracted waves, the end having a larger radius of curvature thereof positioned on the side in the direction of propagation of refracted waves.

Granted: 2014-06-17
Abstract: This invention relates to the use of hydroxybutyrate and poly hydroxybutyrate as components of animal feed or feed additives, as well as to compositions, feed additives and feed containing them. The inventors surprisingly found that hydroxybutyrate and poly- hydroxybutyrate, preferably 3 -hydroxybutyrate and poly-3 -hydroxybutyrate, have a great potential for use in animal feed for modulation of the gut flora. More precisely, it has been found that poly-3 -hydroxybutyrate or a microbial strain capable for producing poly-3- hydroxybutyrate can be used as a potential growth promoter or gut flora modulator by releasing SCFA, preferably 3 -hydroxy butyric acid, in the gut micro flora. Further, the inventors found that 3 -hydroxybutyrate and poly-3 -hydroxybutyrate have a great potential for suppressing or inhibiting pathogenic bacteria in the gastro intestinal tract, e.g. have a antimicrobial activity against strains of Vibrio, E.coli and Salmonella.

Title: Friction loss reduction in viscoelastic surfactant fracturing fluids using low molecular weight water-soluble polymers
Inventor: WOOD WILLIAM
IPC: E21B43/25
Filed: 2007-07-23
Granted: 2011-12-13
Abstract: Adding relatively low molecular weight water-soluble friction loss reduction polymers to an aqueous fluid gelled with a viscoelastic surfactant (VES) increases the critical generalized Reynold's number at which the Fanning friction factor increases and friction pressure starts to increase rapidly. The water-soluble polymeric friction loss reduction additives lower surface pumping pressure in VES- gelled fracturing fluids for a given pump rate, thus lowering hydraulic horsepower (HHP) requirements for pumping fluids downhole, e.g. for hydraulic fracturing or frac packing treatments of subterranean formations.
