Title: Laser diode intensity and wavelength control
Inventor: KAMIN GEORGE W
IPC: H01S5/068
Filed: 1987-04-16
Granted: 1993-03-30
Abstract: LASER DIODE INTENSITY AND     WAVELENGTH CONTROL      ABSTRACT OF THE DISCLOSURE The actual values of intensity and wavelength of the optical signal output from a laser diode are compared  to  desired  values  thereof  to  generate intensity and wavelength error signals. The rates of change of the wavelength and intensity as functions of temperature  and  injection current  about  nominal operating values  of the temperature  and injection current  are  determined  and  used  to  calculate  an injection current error signal and a temperature error signal  for  adjusting  the  injection  current  and temperature, respectively.  The time responses of the injection current and temperature are decoupled, which allows independent adjustment of the time constants of the exponential expressions for injection current and temperature. Providing independent adjustment of the time constants of the injection current and temperature variations permits the desired signal wavelength and intensity to be obtained in a time efficient manner.

Title: Acoustical removal of particles from magnetic matrix
Inventor: GRAHAM MARSHALL D
IPC: B01D35/06
Filed: 1987-05-12
Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for dislodging fragile particles, such as intact biological cells, retained by the separation matrix in a flow chamber of a magnetic separation system.  The apparatus incorporates a piezoelectric transducer which is coupled to the matrix and an associated drive circuit.  The system can operate in a capture phase, whereby fragile particles are selectively captured from a carrier fluid passing through the matrix, with those captured particles being magnetically held in place within the matrix.  In the elutriation phase, an elutriation fluid is passed through the matrix and the drive circuit excites the piezoelectric transducer.  In response to the excitation, the transducer establishes acoustic waves in the elutriation fluid passing through the matrix, vibrating the matrix itself.          The acoustic waves can be ultrasonic.  The acoustic waves and matrix vibration operate to dislodge the intact cells from the matrix, even at relatively low elutriation flow rates.

Abstract: ABSTRACT      This geoelectrical method determines main permeabilities, fracture set permeabilities, fracture set porosities and fracture/ vuggy porosities for layers of rock masses or structures which are filled with liquid or gas.  The method can be used from the surface of the ground and through drilling.  Technical implementation is effected by means of a plurality of linear electrical soundings of differing directions from one point.          Analysis provides the sequence of geoelectrical layers and the resistivity anisotropies of the layers.  By further processing of the anisotropy parameters of a layer, one obtains directionally dependent specific rock body resistivities and the direction of the main permeability.  The layer-specific hydraulic values are calculated according to formulae in which the initial data specific resistivity of the rock, specific resistivity of the rock body, specific liquid resistivity, coefficients, kinematic viscosities and the flow factors are included.  The main areas of application for the procedure are in locating ground water, dam construction, tunnel construction (rock engineering), building renovation, foundation analysis, testing construction, materials, monitoring grouting shields, grouting layers, wall and retainer construction, environmental protection (planned waste disposal sites and old hazards), prospecting for geothermal sources, gas and mineral water, and in the exploration for hydrocarbons.

Title: Round baler having interlock mechanism for assuring post discharge actuation of ejected bale repositioner

Abstract: ROUND BALER HAVING INTERLOCK MECHANISM FOR ASSURING POST DISCHARGE ACTUATION OF        EJECTED BALE REPOSITIONER          Abstract of the Invention A round baler having a shiftable reposi-tioning member for moving a completed,  discharged bale of hay away from the baler is provided with an interlock mechanism for preventing movement of the repositioning member until such time that the bale has been discharged from the chamber.  A sensor is located on a side of the baling chamber to determine the absence of a bale, and preferably takes the form of a rounded element biased toward a position nor-mally protruding into the chamber.  The presence of a bale within the chamber causes the element to shift outwardly and thereby close a valve interposed in a hydraulic circuit for providing motive fluid power to a piston and cylinder assembly that, in turn, drives the repositioning member.  Once the completed bale has been discharged from the baling chamber, however, the element shifts under the bias of a spring toward its normal position protruding into the chamber to thereby close the contacts of the magnetic reed switch and open the hydraulic valve so that the repositioning member may then be activated to shift the bale away from the baler.

Abstract: HEAVY OIL CATALYTIC CRACKING                   ABSTRACT          A fluid catalytic cracking process and apparatus is described which includes a high temperature stripper (hot stripper) to control the carbon level and sulfur on spent catalyst, followed by catalyst cooling to control the regeneration inlet temperature. The high temperature stripper operates at a temperature between 55°C (100°F) above the temperature of a catalyst-hydrocarbon mixture exiting a riser and 816°C (1500°F).  The regenerator inlet temperature is controlled to obtain the desired regeneration temperature 9 regenerator outlet temperature, and degree of regeneration.  The regenerator is maintained at a temperature between 55°C (100°F) above that of the catalyst in the high temperature stripper and 871°C (1600°F).  The present invention has the advantage that it separates hydrogen from catalyst to eliminate hydrothermal degradation, and separates sulfur from catalyst as hydrogen sulfide and mercaptans which are easy to scrub.  The catalyst cooler enables the regenerator and high temperature stripper to be run independently at respective desired temperatures.
