Abstract: A method of controlling a piston pump is disclosed. The method includes actuating a plurality of pistons housed within a cylinder barrel to cause each of the plurality of pistons to engage in reciprocating motion. Fluid supplied to each of the pistons may be regulated by changing a clock position of an intake cam ring to cause a plurality of intake valves to open and close relative to the clock position of the intake cam ring. Fluid discharged by each of the pistons may be regulated by changing a clock position of an exhaust cam ring to cause a plurality of exhaust valves to open and close relative the clock position of the exhaust cam ring.

Abstract: A computer (2) is used to prepare a script (4) of prompts for a media capture device (6) such as a cell phone or a self interview kit. Discrete prompts of the script arc displayed. A camera (14) then captures video clips or other assets with each video clip corresponding to one or more displayed prompt. A clip storage module (18) stores each recorded video clip in a storage unit (20) so as to be related to its corresponding discrete prompts. The clip to prompt relationship provided by the storage module (18) facilitates the editing of the clips into a sequence to produce a complete video presentation or movie. The final video sequence compilation can be performed automatically using the script to define the order of each clip. The automatically edited video sequence may be ordered non-sequentially with respect to the order of the presentation of the discrete prompts.

Abstract: The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. A center section joins the front face section and rear face section and forms part of the top of the isolator. Ribs extending from the front face and the rear face to aid in positioning the isolator. In another embodiment, the front face section and the rear face section each include positioning tabs projecting therefrom to aid in positioning the isolator.
