Abstract: Ultrasonic measurement apparatus 10 includes a transmitter 14 to transmit an ultrasonic signal 16 into an item 12. A receiver 18 receives echoes 20 from the item 12. The apparatus 10 measures the frequency spectrum of the echo 20 and makes a comparison with another frequency spectrum to extract information relating to a change in the item 12. For example, the item 12 may wear during use. A comparison of the frequency spectrum, with previous frequency spectra, allows changes of dimension of the item 12 to be identified. Changes in amplitudes of the frequency spectrum allow changes in roughness to be detected.

Abstract: Ultrasonic measurement apparatus 10 includes a transmitter 14 to transmit an ultrasonic signal 16 into an item 12. A receiver 18 receives echoes 20 from the item 12. The apparatus 10 measures the echo 20 and makes a comparison with another echo to extract information relating to a deposit of additional material at a surface of the item 12. For example, tribofilms or deposits may grow on the surface of the item 12 during use. A comparison of the echo, with previous echoes, allows the additional material to be detected and/or characterised.

Abstract: The instant disclosure is directed to a method of lubricating a sump-lubricated, high efficiency, gasoline-fueled internal combustion engine. Said method involves supplying to the engine a lubricating composition comprising an oil of lubricating viscosity, an anti-wear agent, an ashless antioxidant, a metal-containing detergent, an ashless polyolefin dispersant, and (f) a polymeric viscosity modifier. The disclosure further provides a method of operating a high efficiency sump-lubricated gasoline-fueled internal combustion engine while maintaining or improving at least one of durability, deposit control, oxidation control, fuel economy, and resistance to knock and stochastic pre-ignition.

Abstract: A fluid 10 is contained within a chamber 12. The chamber wall 14 has an inner surface 16 exposed to the fluid 10 and an outer surface 18 separated from the inner surface 18 by the material 20 of the wall 14. Ultrasound 22 is introduced into the material 20. Measurement of the time of flight of the ultrasound 22 through the body 20 allows a measurement to be made of the pressure of the fluid 10.
