Abstract: A method for manufacturing blades for surgical and other uses from either a crystalline or polycrystalline material, preferably in the form of a wafer, comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. When a router is used, through-holes are drilled in the wafer to define the starting locations of the trenches. After the trenches are formed, the wafers are placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or polycrystalline material are removed uniformly, producing single or double bevel blades, with each bevel having one or more facets. Nearly any bevel angle can be machined into the wafer which remains after etching.

The engagement of the cam follower and channel causes the latch member to be rotated about the displacement axis as the latch member is translated along the displacement axis.

Abstract: A cam actuating clamp. The clamp has first and second jaws, with one of the jaws including a surface forming a fulcrum and the other one of the jaws including a projecting arm which contacts the fulcrum when the clamp is in an open position. The clamp is moved from a closed to an open position simply by the user grasping an actuating lever that is pivotally secured to one of the jaws and lifting the clamp, in which the weight of the jaws causes rotation of the jaws, relative to the actuating lever, into an open configuration. A pair of springs secured under tension between the jaws hold the jaws in the open position. The jaws are clamped over a work piece by the user moving the actuating lever into a second position. A camming surface on the actuating lever provides an over center action that enables the springs to both assist in opening the clamp as well as closing the clamp depending upon the position of the actuating lever.

Abstract: A dynamic seal advantageously utilizes a groove on the active side or surface of the seal to capture a leaked lubricant and hydrodynamically pump the lubricant back into the lubricated side of the seal. The groove stops short of the leading edge of the seal that faces the lubricant side thereby forming a static dam between the termination point of the groove and the seal edge. When the fluid pressure within the groove adjacent the static dam exceeds the opening pressure for the seal lip, the lubricant within the groove is pumped back into the lubricant side of the seal. The groove can have an induction zone wherein the fluid pressure rise is gradual and a booster zone wherein the fluid pressure rise is relatively faster than in the induction zone. The booster zone is disposed adjacent the static dam.

The symmetrical pumping elements have ending points that stop short of the seal edge of the seal. The seal may utilize secondary pumping elements that communicate with the primary pumping elements to capture lubricant that is not captured by the primary pumping elements.
