The only element of the valve train coupling a cam to a stem is a cam follower with a depression for receiving the corresponding stem end and a cam engaging surface opposite the depression with the cam follower being held captive intermediate the stem and cam solely by the spring biasing of the stem toward the cam and the engagement of the stem end and the depression.

Abstract: An oil dispersing device in a compresser having a crankshaft with an axial bore therein. An oil pumping device pumps oil upwardly through the axial bore and outwardly through a radial passage communicating with the bore. A cage bearing located in an upper portion of the compressor housing and journalling the crankshaft has a counterbore formed therein which is coaxial with and surrounds the crankshaft and forms an annulus with the outer surface of the crankshaft. Oil passing outwardly through the radial passage pools in the annulus and deflects additional oil exiting from the passage thereby deflecting oil upwardly onto the upper housing wall whereby the oil is cooled by the compressor housing.

Abstract: A method and apparatus for measuring the Gray Scale characteristics of a CRT display wherein a luminance meter surveys a ten percent portion of the total surface area of the screen of the CRT display screen. The luminance meter is positioned far enough from the screen so that the cone surveyed by the luminance meter will intersect the plane of the screen to cause ten percent of the screen surface area to be surveyed. A special test pattern is generated for display on the CRT screen whereby a surveyed area is provided having a sufficiently large surface area and being of uniform brightness. The test pattern also provides for an additional screen area equal in size to the surveyed area. The average picture level for the surveyed area and the non-surveyed area is maintained at fifty percent of peak picture level while the brightness of the surveyed area is varied in incremental steps through the Gray Scale.

Abstract: A horizontal shaft oil pump is provided for use in a compressor comprising an outer housing having an inlet, an outlet, an oil sump, and a crankcase mounted therein. The crankcase has a generally vertically disposed passageway therein in communication with the oil sump, and a crankshaft is horizontally rotatably received in a bore in the crankcase. A reduced diameter portion of the crankshaft forms between the crankshaft and crankcase an annular chamber in communication with the passageway, and a pair of oppositely angularly disposed helical grooves are disposed in the crankshaft on opposite sides of and in communication with the annular chamber. Upon rotation of the crankshaft, a low pressure area is developed in the annular chamber causing lubricant to be drawn upwardly through the crankcase passageway and into the annular chamber. The rotating helical grooves deliver lubricant from the annular chamber to opposite end portions of the crankshaft for lubricating bearings and other moving parts.
