Patent EP-0191203-A2 (EP)
Inventor: LEMELSON JEROME HAL
IPC: C23C30/00
Filed: 1985-01-16
Abstract: An apparatus and method are provided for fabricating cutting tools and tool cutting edges and for improving the structures of cutting tools, particularly the cutting edge portions thereof. In one form, the method involves subjecting the edge EI or edges of a cutting tool 10 such as a blade or other form of cutting tool, to the intense heat of a radiation beam such as an intense light beam generated by a laser or an electron beam generated by an electron gun. The intense heat serves one or more of a number of functions including the vaporizing, eroding or melting of a portion of the material of the surface stratum of a blade or cutting tool adjacent the cutting edge portion thereof and in certain instances including that material which defines the cutting edge. The liquified thin layer of material which is formed and remains adjacent the cutting edge of the tool, tools rapidly as the beam passes, forming a non-crystalline layer of the metal or alloy from which it is melted, which layer is harder and more corrosion resistant than the original alloy thereby providing an improvement in the cutting edge and material adjacent thereto which is subject to attrition during the cutting operation. The substrate of which the hard surface stratum is formed may comprise the base of the cutting tool or a coating thereon wherein such base or coating may be made of alloys of such metals as nickel, cobalt, chromium, tungsten, titanium, silicon, zirconium, and other hard metals. If the cutting tool is a preshaped object, computer controlled means is employed to predeterminately position the tool and beam generating means and to operate the beam to effect a predetermined blade hardening operation. If the cutting tool is in the form of a blade it may be continuously fed past the radiation beam generator which op-(Continuation next page)   erates continuously on or adjacent to the preshaped edge thereof to form a hard coating or surface stratum adjacent to and over the edge. A finishing operation such as gringing, honing and/or lapping operation may be employed against the cutting edge after the operation of the beam thereon to finish the edge as may such operations be performed prior to the operation of the beam as well as after the beam operation. In a particular form, the beam or a plurality of beams may be predeterminately operated to partially or completely form the cutting edge while the tool is in operation or while it is inoperative but held by a tool holder or tool changer so as to sharpen or enhance the operation of the tool after it has experienced cutting operations. In yet another form, one or more intense radiation beams may be focused and utilized to vaporize or melt metals or alloys forming or coated on cutting tools for the purpose of forming or sharpening cutting edges thereof. Two electron or laser beams may operate per set or in combination for example, to vaporize the edge of a blade or cutting tool in a manner to sharpen same after it has become dull or during its formation.

Abstract: A process for the deformation of a hollow workpiece comprising an orientable, thermoplastic polymer by passage in the solid phase through a die having both an entry side and an exit side, which process comprises providing the hollow workpiece at the entry side of the die; applying to the hollow workpiece from the exit side of the die a tension insufficient to cause tensile failure of the workpiece but sufficient to deform the hollow workpiece by drawing it with reduction in its bulk cross-sectional area in the solid phase simultaneously through the die and over an internally positioned former having a cross-sectional area greaterthan the initial internal coss-sectional area of the hollow workpiece; and collecting the deformed hollow workpiece from the exit side of the die.

Abstract: The disclosed meters employ mechanical radiant energy to determine the flow velocity of flowing material. Mechanical radiant energy is propagated through the flowing material in two directions to permit the material to cause a variance between the average velocity at which the energy travels in a first direction from the average velocity at which the energy travels in a second direction. Since the variance in average velocities is due to the movement of the material and is related thereto, the variance, and the difference in time required for the energy to propagate through the material, can be used to determine the flow velocity of the material. One embodiment employs the following equation to calculate the flow velocity:     where t. and t, represent the time required for the energy to traverse the path in each direction. Another embodiment transmits energy pulses in each direction in groups of at least two pulses and imposes a time delay between the time each pulse finishes propagating along the path and the transmission of the next pulse. The time required for the energy to propagate along the path In each direction is determined from the time required to transmit along the path all the energy pulses of each group and the total duration of the time delays. A further embodiment examines the received energy and determines whether the level of the transmitted energy should be altered to improve signal processing. A further embodiment assumes that the energy has reached the end of the path, and is therefore able to determine the time required for the pulse to traverse the path, by defining a receive point which is a predetermined point at which the received signal crosses a reference axis following the peak level of the signal. The preferred embodiment combines all the features identified above.
