Abstract: A method for controlling an electric motor driving a hydraulic pump for a battery-powered electric mobile machine includes receiving one or more command signals for one or more hydraulically-driven systems. The method also includes determining a minimum pump speed for each of the one or more hydraulically-driven systems, and determining a highest minimum pump speed for the one or more hydraulically-driven systems. The method further includes converting the highest minimum pump speed to an electric motor command, and sending the electric motor command to the electric motor.

Abstract: An apparatus for determining density of fluid returning from a wellbore (“return fluid”) during drilling of the wellbore being drilled using a drill string having a drill bit at an end thereof is disclosed. The apparatus in one embodiment includes a first nucleonic densitometer placed on outside of a return line carrying the return fluid from the wellbore that includes drilling fluid supplied to the drill string and cuttings cut by the drill bit during drilling of the wellbore and a processor that determines the density the return fluid from measurements provided by first nucleonic densitometer.

Abstract: A weatherstrip for a motor vehicle includes a generally U or J-shaped body of thermoplastic olefin (TPO), polypropylene (PP) having integrally formed lips or sealing flanges of more flexible thermoplastic vulcanizates (TPV) and a show surface of thermoplastic polyolefin (TPO). The body includes longitudinally spaced apart latch members which secure the weatherstrip to a vehicle body. The sealing flanges preferably include flocking on the surfaces which contact and ride against the window glass. The thermoplastic polyolefin show surface bonds directly to the TPV or polypropylene substrate and provides a color and gloss match to the paint on the vehicle body. Improved weatherstrip performance and improved vehicle appearance are both achieved by the present invention.
