Granted: 1993-08-10
Abstract: Applicants:  James P. Cox and Kelly K. Cox Title:    Gas Scrubbing Apparatus and Process ABSTRACT           Scrubbing apparatus for effecting contact between polluted air and a scrubbing liquid may define a serpentine path mounted on a rooftop, a tank in which contact between the polluted gas and the scrubbing liquid is effected by projecting the scrubbing liquid onto a rotating propeller to effect atomization of the scrubbing liquid or contact between the scrubbing liquid and the polluted air can be effected by dripping scrubbing liquid onto filters through which the polluted air passes.  Purification of the scrubbing air is enhanced by producing turbulence in the air carrying the scrubbing liquid by passing the air carrying the scrubbing liquid between closely adjacent, flexible, vibrating sheets disposed parallel to the gas flow.          The vibrating characteristics of the flexible sheets can be altered by stretching such sheets and/or by placing such sheets alongside a hard surface struck by the flexible sheets.

Title: Chopper wheel alignment device
Inventor: ORKOSALO JORMA J
IPC: G01G17/02
Filed: 1988-03-11
Granted: 1994-01-25
Abstract: CHOPPER WHEEL ALIGNMENT DEVICE            ABSTRACT OF THE DISCLOSURE       A device for characterizing the formation of a sheet material is described.  The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material moves through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight.  The basis weight sensor includes a light source for directing a beam of light at the moving sheet and a light detector which detects the beam after it passes through the sheet.  This detector produces a signal indicative of the intensity of the detected beam and transmits the signal to the signal processing circuitry.  To calibrate the signal processing circuitry, a rotatable opaque wheel having a plurality of slots is positioned in the path of the light beam.  The rotating wheel alternately blocks the light beam and allows the beam to pass through the slots to the detector.  By rotating the wheel at a predetermined speed, the signal produced by the light detector is modulated at a predetermined frequency dependent upon the rotational speed of the wheel and the number of slots in the wheel.  After calibration, an electromagnet rotates and holds the wheel in a position wherein the light beam passes, unobstructed by the wheel, through one of the slots.

Title: Process for the preparation of meso 2,5-dihaloadipates
Inventor: O'NEILL BRIAN T
IPC: C07C51/62
Filed: 1988-08-05
Granted: 1993-10-26
Abstract: PROCESS FOR THE PREPARATION OF    MESO 2,5-DIHALOADIPATES                    Abstract The present process produces the meso dialkyl 2,5-dihaloadipate from a mixture of the racemic dialkyl 2,5-dihaloadipate and meso 2,5-dihaloadipate.  In the disclosed process, a 2,5-dihaloadipoyl halide is formed under conditions which result in the formation of an acidic compound.  The 2,5-dihaloadipoyl halide is then esterified under conditions wherein the ester of the dihaloadipoyl halide is allowed to remain in contact with the acidic compound, thus allowing the racemic diester to epimerize in the presence of the acidic compound to the meso form and then the meso diester spontaneously crystallizes. In the last stage, the meso diester produced is removed.

Granted: 1995-05-02
Abstract: A method and apparatus for electrolytically assisting the mechanical shaping of a workpiece is provided which is particularly useful for precision machining.  A tool is used comprising an electrically conductive (copper alloy) tool shank, a cutting tool of an electrically insulating material (reinforced ceramic), and means for flooding a gap, between the tool shank and the localized electrically conductive surface layer to be shaped, with a stream of electrolyte.  With the electrolyte flowing, and a low voltage, direct current applied across the gap using the localized, electrically conductive surface layer as the anode and the tool shank as the cathode, the structure of the localized, electrically conductive surface layer of the workpiece just ahead of the tool is weakened structurally sufficiently to be removed easily by the cutting tool in discrete form and carried away from the tool by the stream of electrolyte.  The structural weakening of the surface layer, rather than electrolytic removal thereof, is obtained by using an appropriate d.c. current only for a sufficient length of time for the surface layer to be structurally weakened.
