  • Patent number: 9222049
    Abstract: The present invention provides a lubricating composition for use in the crankcase of an engine comprising a base oil and one or more additives, wherein the base oil comprises a Fischer-Tropsch derived base oil and wherein the lubricating composition has a kinematic viscosity at 100 C (according to ASTM D 445} of below 5.6 cSt and a Noack volatility (according to ASTM D 5800) of below 15 wt. %.
    Type: Grant

  • Publication number: 20050264274
    Abstract: An electrical conductor locating device comprises a pulse generator and a detector. The pulse generator includes a transformer with outputs for connecting to two positions along the electrical conductor to define a closed loop. The current in the closed loop produces an electromagnetic field around the conductor. The detector is comprised of a magnetic field sensor connected through a filter to the input of an amplifier. The output of the amplifier is connected to an indicator, such as a LED. When the sensor is moved perpendicularly closer to the conductor, it senses an increasing magnetic field strength so the amplifier drives the indicator at greater intensity. When the sensor is directly aligned with the conductor, the sensor is inside the equipotential point of the magnetic field where the field strength approaches zero, so the amplifier drives the indicator at close to zero intensity and thus pinpoints the conductor.

  • Patent number: 4115690
    Abstract: A backscatter measurement device for measuring the thickness of a coating on a strip of substrate material moving from a feed supply to a take up location at a predetermined speed. A measurement wheel is provided on the rim of which are mounted backscatter probes for irradiating and detecting the backscattered radiation from the coated substrate. The coated strip of substrate material is threaded around the outer surface of the rim. The measurement wheel is rotated at a speed such that the tangential speed of a point on the rim equals the speed of the moving strip whereby the probe and an adjacent point on the strip are stationary relative to one another while the point on the strip is adjacent the rim. Thus thickness measurements may be taken without stopping the movement of the coated strip.
