Patent number: 4515720Abstract: Preparation of 9-acetyl-6-hydroxy-4-methoxy-7,8,9,10-tetrahydronaphthacene-5,12-dione (the object intermediate), and precursor compounds to the object intermediate. Preparation of the object intermediate according to the invention begins from 2-(2-hydroxyethyl)-bicyclo[2.2.2]oct-5-ene, wherein the latter is converted to 6-acetyl-4a,5,6,7,8,8a-hexahydro-1(4H) naphthalenone (one of the two precursor compounds) which is subsequently reacted with a phenylsulfonyl isobenzofuranone to furnish, regiospecifically, 9-acetyl-5,12-dihydroxy-4-methoxy-6(11H)-hexahydronaphthacenone (the other of the two precursor compounds). Heating the hexahydronaphthacenone in dimethylforamide under an oxygen atmosphere gives the object intermediate.Type: GrantFiled: March 11, 1983Date of Patent: May 7, 1985Assignee: Oregon Graduate Center for Study & ResearchInventors: Frank M. Hauser, Dipakranjan Mal

Patent number: 4490329Abstract: A method for the implosive consolidation into a solid body of a mass of free particles, which mass consists, selectively, entirely of amorphous particles, or a mixture of amorphous and nonamorphous particles. During the consolidation act, pressure and temperature are controlled in a manner which assures that the consolidated amorphous particles in the solid body exhibit substantially the same amorphous characteristics as those displayed by the unconsolidated, free amorphous particles.Type: GrantFiled: September 8, 1983Date of Patent: December 25, 1984Assignee: Oregon Graduate Center for Study and ResearchInventors: Alan W. Hare, Lawrence E. Murr, F. Paul Carlson

Patent number: 4412173Abstract: Apparatus using leakage current through a sample to determine resistivity. An optically active material of the type which changes the polarization of a light beam passing therethrough, responsive to an electric field, is placed between a first pair of conducting plates. The sample is placed between a second pair of conducting plates which are in parallel connection with the first pair of plates. A light source transmits light through the material and a light detector detects changes in polarization of the light which emerges from the material. Each pair of plates is charged and the rate of discharge of the plates is monitored by the light detector.Type: GrantFiled: January 26, 1981Date of Patent: October 25, 1983Assignee: The Oregon Graduate Center for Study and ResearchInventor: Gail A. Massey

Patent number: 4367244Abstract: Method for monitoring the weight of glue sprayed on a veneer surface, where the light reflectance from droplet-covered regions on the surface differs from that of uncovered surface regions. According to the method, a beam of light is directed onto the sprayed surface of a relatively moving veneer, and the light reflectance from a zone within the illuminated surface area is detected to produce a signal which varies according to instantaneously detected reflected light level. A signal-handling circuit transforms the signal to a binary data stream composed of one and other data states representing reflected light levels from droplet-covered and uncovered regions on the surface, respectively. The data stream is processed to compute the weight of glue sprayed on the surface.Type: GrantFiled: November 9, 1981Date of Patent: January 4, 1983Assignee: Oregon Graduate Center for Study and ResearchInventor: James F. Holmes

Patent number: 4300836Abstract: A scanner profiling system for locating and "mapping" a selected "feature" in a three-dimensional object, which "feature" is nearest with respect to a defined datum plane. The system includes a laser-distancing-instrument (LDI), and a cooperating motor-driven mirror apparatus which is operated under digital computer control to shift the scan axis of the system, in preselected steps, throughout a defined scan field. Object "feature" location, and related scan orientation data which are obtained during a scanning operation, effect computer scan control, whereby scanning "attention", within the total scan field, is directed particularly to "track" the selected "feature".Type: GrantFiled: October 22, 1979Date of Patent: November 17, 1981Assignee: Oregon Graduate Center for Study and ResearchInventors: Holmes, Jones F., Ralph L. Jacob

Patent number: 4283122Abstract: Apparatus for streaking a beam of light employing a crystal in which an electromagnetic wave pulse induces a synthesized traveling lens. Surfaces on opposite sides of the crystal act as light reflectors to create multiple cross-reflections of the beam relative to the crystal, thus to enhance the lensing effect of the crystal. Production of the electromagnetic wave pulse is coordinated with impingement of a beam of light, and the geometry of parts is arranged whereby each coherent wave front in the beam, as it passes multiple times through the crystal, on each such passing encounters the same substantially constant lens condition which has been induced in the crystal.Type: GrantFiled: October 29, 1979Date of Patent: August 11, 1981Assignee: Oregon Graduate Center for Study and ResearchInventors: Richard A. Elliott, Gail A. Massey, John B. Shaw

Patent number: 3947688Abstract: A method for obtaining efficient production of short-wavelength, continuously-tunable ultraviolet light by parametric mixing of optical frequency radiation in a nonlinear crystal. The method involves mixing the second harmonic of a tunable, visible-wavelength laser, an organic dye laser, for example, with the fixed-wavelength output of a near-infrared laser, e.g., a Nd:YAG laser, in a conventional nonlinear crystalline material such as ADP or KDP.Type: GrantFiled: August 26, 1974Date of Patent: March 30, 1976Assignee: Oregon Graduate Center for Study and ResearchInventor: Gail A. Massey

Patent number: 3943361Abstract: A system for measuring a lineal dimension of a light reflective object. Sequentially generated light markers forming a raster are projected toward the object to be measured, with the markers traveling along individual, parallel paths which are uniformly spaced-apart along the dimension being measured. Markers intercepted and reflected back by the object are photoelectrically detected and counted to determine the size of the object along the measured dimension.Type: GrantFiled: August 7, 1974Date of Patent: March 9, 1976Assignee: Oregon Graduate Center for Study and ResearchInventor: Carl T. Miller
