Abstract:
The present invention discloses a square root algorithm that uses a multiplication operation, an exclusive-or operation, a bit right shift operation, a bit left shift operation and a comparison operation to compute a square root for an integer in a binary form, such that more computations can be processed in a shorter time, and lower the cost for a programmable digital calculator and digital circuits which comes with a central processing unit of a computer system, and thus allowing the algorithm of the present invention to be used extensively.
Abstract:
A mechanism for pumping slurry includes a housing for receiving the slurry and two cylinders secured to the housing for drawing the slurry into and out of cylinders. A pipe is pivotally secured to the housing and has one end for selectively aligning with either of the openings and for allowing the slurry to be supplied into the pipe by the cylinders alternatively. The housing includes a pivotal follower for rotating the pipe and one or more actuators for rotating the follower and the pipe.
