Title: Lens edging machine bevel control process
Inventor: STROPE TODD R
IPC: G05B19/18
Filed: 1993-11-23
Granted: 1998-06-30
Abstract: An improved process for positioning a bevel along the edge  of  an opthamalic  lens  computes  point-to-wheel  data definitive of a planar relationship between the lens and the wheel,  stores the point-to-wheel data,  computes corrected horizontal displacement data definitive of a three dimensional relationship between the  lens,  the wheel  and a plot of sequential contact points therebetween using the computed point-to-wheel  data,   stores  the  corrected  horizontal displacement data, and controls the relative positions of the edging wheel  and the  lens  in  response to the corrected horizontal displacement data.    The point-to-wheel  data  is  computed by  sequentially testing at successive incremental points of the point-to-wheel data at a beginning reference angle of the lens to determine a transition point at which the wheel ceases to increase and begins to decrease its displacement from the lens.     This  sequential  testing  is  repeated  at  successive incremental points for sequentially successive incremental changes in the reference angle to determine a transition point for each incremental change.     The corrected horizontal displacement data is computed by sequentially testing at successive incremental angles of a radius originating at a center of rotation of the lens at a beginning  reference  angle  of the  lens  to  determine  an incremental angle at which the lens initiates contact with the wheel.   This sequential testing is repeated at successive incremental angles at each sequentially successive incremental change in the reference angle to determine an incremental angle at which the lens initiates contact with the wheel for each incremental change.     Preferably,  the  beginning  reference  angles  and  the successive incremental changes in the reference angle of the point-to-wheel  computing  and  the  corrected  horizontal displacement computing are identical and sequential testing at successive incremental points and at successive incremental angles occurs simultaneously for each sequentially successive incremental change in the reference angle.

Abstract: A process for removing elemental sulfur from fluids such as refined petroleum products transported through pipelines normally used for the transport of sour hydrocarbon streams. The sulfur containing fluids are mixed with an immiscible aliphatic solution containing an inorganic caustic material, methanol or aqueous alcohol and an inorganic sulfide or hydrosulfide capable of reacting with the elemental sulfur in a mixing zone to form a polysulfide present in the immiscible alcoholic solution, passing the mixture of fluid and immiscible alcoholic solution to a phase separation zone wherein mixture separates into a fluid phase of reduced elemental and total sulfur content and an immiscible alcoholic phase containing polysulfides, recovering the fluid phase of reduced sulfur content from the phase separation zone, recovering the immiscible alcoholic phase containing polysulfide from the phase separation zone and recycling the immiscible alcoholic solution to the mixing zone. Alcohol from the spent immiscible alcoholic solution may be flash-distilled and recycled for reuse in the process.
