Patent number: 5573459Abstract: The invention provides an improved method and apparatus for separating fruits, such as tomatoes, from vines. The invention uses feeder bars to provide tomatoes to a shaker brush a first time. The vines are allowed to fall out of the shaker brush to a shaker conveyor. The shaker conveyor conveys the vines into/the shaker brush a second time, and then to a vine reel, thus providing an improved separation of tomatoes from the vine.Type: GrantFiled: May 19, 1995Date of Patent: November 12, 1996Assignee: FMC CorporationInventor: David J.

Patent number: 5493904Abstract: The invention provides a method and apparatus for measuring the quality of a coating on a plate. The invention uses a method of measuring the impedance of a coating on a plate, which uses the steps of placing the coating on a plate in a chamber, and then placing a counter electrode in the chamber so that the coating lies between the plate and the counter electrode. A reference electrode is placed in the chamber so that the coating lies between the reference electrode and the plate, and the chamber is filled with a fluid with an ionic substrate. A potentiostat induces a voltage between the plate and the reference electrode, and impedance of the coating is measured to determine the quality of the coating.Type: GrantFiled: August 24, 1994Date of Patent: February 27, 1996Assignee: FMC CorporationInventors: Hong Shih, Manuel S.

Patent number: 5026259Abstract: The invention uses a fluid stored at a low pressure and provides the fluid at a high pressure. The invention allows the low pressure fluid to flow to a fluid bore of a differential pump and from the pump to a fluid pressure regulator. After flowing through the regulator the fluid is converted to a gas which is directed to a gas bore of the differential pump. By controlling the flow of gas entering and being exhausted from the gas bore, the invention provides pressure to the fluid. By setting the regulator, the high pressure fluid can be set at predetermined values. Because the invention only needs a low pressure fluid, the inventive apparatus has a low mass, and therefore would be useful in rocket propulsion systems.Type: GrantFiled: July 9, 1990Date of Patent: June 25, 1991Assignee: The United States of America as represented by the United States Department of EnergyInventors: John C. Whitehead, Don G. Swink

Patent number: 4834497Abstract: Particular gases or liquids are detected with a fiber optic element (11, 11a to 11j) having a cladding or coating of a material (23, 23a to 23j) which absorbs the fluid or fluids and which exhibits a change of an optical property, such as index of refraction, light transmissiveness or fluoresence emission, for example, in response to absorption of the fluid. The fluid is sensed by directing light into the fiber optic element and detecting changes in the light, such as exit angle changes for example, that result from the changed optical property of the coating material. The fluid detector (24, 24a to 24j) may be used for such purposes as sensing toxic or explosive gases in the atmosphere, measuring ground water contamination or monitoring fluid flows in industrial processes, among other uses.Type: GrantFiled: February 27, 1987Date of Patent: May 30, 1989Assignee: The United States of American as represented by the United States Department of EnergyInventor: S.

Patent number: 4803049Abstract: An apparatus is provided for remotely monitoring pH. A support material is provided on which organic dye molecules are covalently attached at a surface density falling within a predetermined range. The pH dependent fluorescence response of the bound organic dye molecules depends critically on surface density of the organic dye molecules bound to the support material and the nature of the covalent linkage betwen the organic dye molecules and the support material. The invention is operated by contacting the support material on which the organic dye is attached with the fluid whose pH is to be determined. When in contact, the organic dye on the support material is illuminated so that it is caused to fluoresce. The intensity of organic dye fluorescence is then related to pH.Type: GrantFiled: December 12, 1984Date of Patent: February 7, 1989Assignee: The Regents of the University of CaliforniaInventors: Tomas B. Hirschfeld, Francis T. Wang

Patent number: 4737343Abstract: An optrode is provided for sensing dissolved gases or volatile components of a solution. A fiber optic is provided through which light from an associated light source is transmitted from a first end to a second end. A bubble forming means, such as a tube, is attached to the second end of the fiber optic, and an indicator material is disposed in cooperation with the bubble forming means adjacent to the second end of the fiber optic such that it is illuminated by light emanating from the second end. The bubble forming means causes a gas bubble to form whenever the optrode is immersed in the fluid. The gas bubble separates the indicator material from the fluid. Gases, or other volatile components, of the fluid are sensed as they diffuse across the gas bubble from the fluid to the indicator material.Type: GrantFiled: January 21, 1986Date of Patent: April 12, 1988Assignee: The Regents of the University of CaliforniaInventor: Tomas B. Hirschfeld

Patent number: 4729668Abstract: A method and apparatus are provided for remotely monitoring temperature. Both method and apparatus employ a temperature probe material having an excitation-dependent emission line whose fluorescence intensity varies directly with temperature whenever excited by light having a first wavelength and whose fluorescence intensity varies inversely with temperature whenever excited by light having a second wavelength. Temperature is measured by alternatively illuminating the temperature probe material with light having the first wavelength and light having the second wavelength, monitoring the intensity of the successive emissions of the excitation-dependent emission line, and relating the intensity ratio of successive emissions to temperature.Type: GrantFiled: April 22, 1986Date of Patent: March 8, 1988Assignee: The United States of America as represented by the United States Department of EnergyInventors: S.
