Abstract: Abstract of the Disclosure A skiing device securable to each leg of a skier for providing flexural knee and leg support.  An upper support means positionable about the skier's leg above the knee is interconnected by spring means with a lower support means positionable about the skier's leg below the knee.  The spring means are securably maintained within coupling means mounted to the upper and lower support means.  In this manner, with the skier in a crouched position, part of the upper body weight is supported other than by the knees of the skier, and the skier can more easily absorb bumps while maintaining better balance and control over the skis.

Title: Hydraulic valve with components formed to regulate and/or to eliminate the creation of severe electrokinetic streaming current, and its wall current and the method and criteria tobe followed in forming their metering edges which create the overall metering passageway
Inventor: KIRKBRIDE DAVID W
IPC: F16K25/04
Filed: 1977-04-22
Granted: 1979-04-10
Abstract: ABSTRACT OF THE DISCLOSURE           Hydraulic valves such as hydraulic flow control valves, pressure regulating valves, and servo valves are all formed with metering passageways which reduce and eliminate their susceptibility to electro-kinetic corrosion erosion that occurs at very low flow when the valves are in their null position or nearly shut off.  The metering passages and the metering edges comprising the overall metering passageways are shaped to favorably control the flow character-istics of phosphate ester based fluids, which, if not controlled favorably would produce severe electrokinetic streaming current and its wall current, which would induce electro-kinetic corrosion erosion.  The shapes and dimensions of the metering passages and metering edges are derived from the results of a mathematical quantitative analysis.     In one embodiment of a hydraulic valve, the sleeve, i.e. the non moving member, of the relatively moving metallic hydraulic valve components, has the orifice of the intake passageway, which thereby is serving as part of a hydraulic fluid metering passageway, formed with a rounded metering edge, when viewed in a geometric plane parallel to the axis of the intake passageway, and also formed with spaced parallel metering sides joined at each of their spaced ends by curved corners, and tangent thereto, also by concave metering end edges, formed on the arcs of circles, when viewed in a geometric plane perpendicular to the axis of the intake passageway.  Also in this embodiment, the slide, i.e. the moving member movable at right angles to the intake passageway, has its leading cylindrical circumferential edge, which thereby is serving as part of a hydraulic fluid metering passageway, formed with a rounded metering edge.
