Abstract: A lifting top drive sub sea staging cement head in which cement slurry flows from outside into its central bore, thru a rotating swivel connection. The cement head has a rotatably indexable reservoir cylinder with multiple cells which may be loaded with balls, and/or darts, and/or staging bombs. One first cell is kept open for circulation. The cylinder is rotatably aligned, at will to the flow path, so that the staging elements may be washed down the drill string. In addition, the cement head is hydraulically remotely controlled such that no operators protrude from the smooth body, yet the remote system may be manually over-ridden.

Abstract: A method and apparatus for heating fluid comprising a rotor with a first hole and a second hole. The apparatus comprising an intake port, a discharge port and a pocket spaced apart from the rotor. The fluid enters the apparatus through the intake port and the rotor rotates causing the fluid to flow through the first hole, collide with the pocket, flow though the second hole and leave the apparatus through the discharge port.

Abstract: A method of generating heat and a heat generator comprising a rotor with an intake port, a plurality of inner and a plurality of outer holes. The heat generator also comprises a front rotor housing for housing the rotor. The front rotor housing has a plurality of pockets and a discharge port. The fluid enters the heat generator through the intake port and the rotor rotates forcing the fluid through said the inner holes causing the fluid to collide with the pockets and return through the outer holes and flow out of the heat generator through the discharge port.
