Abstract: A method for coining a precision corner break on an oil metering flat for a rotor of a power steering rotary valve is provided. The method comprises the first step of placing a workpiece to be coined in a first floating position set by a clamping and orientating device where the workpiece is generally aligned but adjustable for further coining orientation if necessary. The next step comprises engaging the workpiece with a plurality of circumferentially spaced coining dies. The workpiece floats from the first floating position to a second coining position upon engagement by the dies. The last step comprises coining the workpiece to a precision depth selectively adjustable by adjustment of a motion conversion means. The press assembly includes fixed and movable platens, the movable platen being powered by a power cylinder assembly to direct the movable platen in a longitudinal direction in the press.

Abstract: A method of manufacturing a cylindrical valve sleeve is provided. The method includes the steps of providing a cylindrical valve having an inner wall, an outer wall and an end shoulder disposed therebetween. The shoulder is machined to form a circumferential groove which defines a swedgeable shoulder area on the shoulder. The inner wall is broached to include a plurality of open ended longitudinal slots radially spaced about the inner wall. Next, the shoulder areas are swedged at preselected spaced positions contiguous to the end portions of the longitudinal slots to deform the preselected positions axially and radially inwardly into the slot end portions whereby the slot end portions are substantially closed relative to the inner wall of the sleeve. The preselected spaced positions are discontinuous relative to the shoulder to minimize the necessary force and resulting deformation.

Abstract: An arrangement for making a hard copy of a cathode ray tube display. Each horizontal line of a video signal is subdivided into a predetermined number of intervals. The amplitude of the video signal within each interval is digitized, and the digitized data, after being stored in a first-in-first-out shift register, is recorded on any desired recording medium, such as heat-sensitive or electro-sensitive paper. Each horizontal line is printed along a line on the paper, and the paper is advanced by one line when the next horizontal line of the video signal is ready to be recorded. The subdividing of each horizontal line is carried out by a phase-lock loop which functions as a frequency multiplier and provides a predetermined number of pulses for each horizontal sync pulse. Each horizontal line being processed is identified by a line counter to ensure that the horizontal lines of a frame are sequentially printed.

Abstract: An elongated unitary center-sill-and-center-brace member for use with sectionalized railroad car center sills is disclosed herein.
