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: Methods and apparatus relate to ultrasound measurement of a dimension such as the thickness (11) of an item (12) which may be worn over time by contact with an item (14). An ultrasonic transceiver (18) couples ultrasound into the item (12). Outgoing ultrasound i results in echos r returning to the transceiver (18). This allows calculation of time of flight to yield a value for the thickness (11). In the examples prescribed, the measurement is repeated a plurality of times in a specified period to extract a dimension from each received signal. Information extracted from the plurality of received signal is used to produce a single value indicative of the dimension of the item (12) over the specified period.

Abstract: Ultrasound generating apparatus (10) comprises an arbitrary waveform generator (12) to provide a waveform output at (14), representing a waveform. A power amplifier (16), which may be an operational amplifier, is operable to amplify the waveform output (14) in power and amplitude to provide a power output (18) for applying to an ultrasonic transducer (20).
