The present invention is a class of organosilicone terpolymers which may be used to abate the foaming of diesel fuel at silicon levels below 1.2 ppm. Said silicone terpolymers are modified alkyl phenol derivatives and polyethers grafted on a polysiloxane copolymer. Said polysiloxane terpolymer has a structure of MDxD*yD**zM, where M is O.5Si(CH3)3, D is a OSi(CH3)2, D* is OSi(CH3)R, R is a polyeth...

A self-propelled steerable robot emits ultrasonic waves in forward, rightward and leftward directions. On the basis of detecting those waves after being reflected from the walls, a controller on the robot determines an angle of travel of the robot relative to a wall of a room, enabling the robot to be turned and oriented parallel to opposite walls of the room. By then emitting waves toward those o...
