Patent number: 6420866Abstract: An apparatus and method used to detect metallized containers or other objects in closed packages traveling in a conveyor stream. The apparatus includes a pair of coil units mounted in association with a packaging conveyor such that the closed packages will pass therebetween. Appropriate field generation circuitry are connected to the coil units for producing a magnetic field. When the metallized containers pass through the magnetic field, the impedance across the coils will vary. The varying impedance is measured continuously, thus giving an indication as to whether the metallized object has been detected. If the package is nonconforming, steps can be taken to automatically remove it from the conveyor stream.Type: GrantFiled: September 21, 1998Date of Patent: July 16, 2002Assignee: Reliance Electric Technologies, LLCInventors: Ira B.

Patent number: 6225812Abstract: A method and apparatus for measuring the amount of free water contained within a substance includes a waveguide having front and back sides disposed opposite each other. The waveguide defines a chamber for propagating a microwave signal therethrough. The waveguide has an end perpendicular to the front and back sides which forms a short within the chamber. The front and back sides each have an aperture for passing a substance therethrough. A microwave signal in the frequency range of 10-25 gigahertz is directed through the chamber wherein the generated microwave signal is reflected back from the short of the end. The generated and reflected signals form a ratio which is used by a microprocessor along with the measurement from an adjacent sensor that provides a dielectric constant measurement corresponding to the density of the substance in order to determine a weight of the substance compensated for free water.Type: GrantFiled: June 25, 1998Date of Patent: May 1, 2001Assignee: Rockwell Technologies, LLCInventors: David L.

Patent number: 5932055Abstract: Direct Metal Fabrication of metal parts is accomplished with a continuous thermal process in which partial reduction of the "green form" part leaves a thin carbon film that maintains the part's structural integrity. The remaining carbon catalyzes a eutectic reducing element to diffuse throughout the part forming organo-metallic bonds that bind the homogenized metal alloy. Supersolidus liquid phase sintering (SLPS) densities the alloy to provide a final part of parent material quality. The DMF process can be used in magnetographic printing to imprint an image.Type: GrantFiled: November 11, 1997Date of Patent: August 3, 1999Assignee: Rockwell Science Center LLCInventors: Kenneth J.

Patent number: 5873966Abstract: A method and system for manufacturing units of production enables the location of a splice to be accurately determined, so that only the unit of production containing the splice can be rejected without requiring additional units of production which are entirely free of defects to also be rejected. According to the method, first and second webs of material are spliced together so as to create a splice. The splice is marked with a magnetic marker. After the units of production are assembled, including a unit of production which contains the splice, the magnetic marker is magnetized. The magnetizing step occurs after the assembling step so that the orientation of the magnetic field remains parallel to the sensing direction until the magnetic field is detected. The magnetic marker is detected with a detector which has a plurality of closely spaced magnetic sensors.Type: GrantFiled: October 14, 1997Date of Patent: February 23, 1999Assignee: Reliance Electric Industrial CompanyInventors: Ira B.

Patent number: 5698986Abstract: A cylindrical microwave cavity 12 has a pinched center 28, 30. Two apertures 28, 30, one in the center. of each face of the cylinder 10, provide access for a gas/powder mixture 124 having a dielectric coefficient depending on its density or some other measurement of interest. The faces 20, 22 of the cylinder 10 are much farther apart at the unpinched periphery, which comprises most of the volume of the cavity. The wider spacing allows an antenna 34 to be placed in the cavity 12, and provides a high Q-factor to maximize the sensitivity of the cavity 12. At the same time, certain resonance modes are greatly affected by a change in the dielectric coefficient of the gas/powder mixture 124 in the pinched portion 28, 30. The density of the powder or any other convenient variable may thus be servoed to any desired value. The powder 124 may be blown through the cavity 10, encased in tube 120 affixed to the cavity 12.Type: GrantFiled: February 12, 1996Date of Patent: December 16, 1997Assignee: Allen-Bradley Company, Inc.Inventors: David L.

Patent number: 5349154Abstract: A swirl flow microwave plasma torch is provided for the growth of diamond films. The swirl flow torch incorporates an injection nozzle that directs reactant gases into a cylindrical flow tube extending through the center of a tuned microwave cavity. The outer surface of the nozzle comprises a contoured, conical shape that causes inert gas, directed tangentially against the outer surface of the nozzle, to swift in a helical path that surrounds and confines the reactant gas emerging from the nozzle. The tuned cavity is coupled to a microwave energy source to generate a highly localized plasma in the reactant gas in the center of the sheathing swirl of inert gas. The swirl of inert gas contains the plasma in a well-defined shape, prevents in-diffusion of undesirable gases, forms a boundary layer to prevent plasma migration, and provides flow tube cooling. The reactant gas flow forces the plasma out of the flow tube to form a plasma flame that can be impinged on a substrate to induce diamond growth.Type: GrantFiled: December 17, 1992Date of Patent: September 20, 1994Assignee: Rockwell International CorporationInventors: Alan B.

Patent number: 4888547Abstract: A meter measures the flow rate of a mixture by measuring a frequency characteristic of microwave propagation within a waveguide which forms a part of the conduit through which the mixture flows. Spaced apart slots in the waveguide form transmitting and detecting antennas which are connected to the output ports of a microwave bridge. An oscillator generates microwaves which are fed to the input of the microwave bridge. The output of the bridge is the difference in power transmitted through the two antennas. This signal is fed to a phase sensitive detection system and the output can be correlated to the flow rate of the mixture. In one embodiment, a computer control unit and computer controlled switches are provided to switch the microwave bridge in and out of the circuit so that both the flow rate and the concentration of an ingredient can be measured.Type: GrantFiled: January 23, 1989Date of Patent: December 19, 1989Assignee: Rockwell International CorporationInventors: Vincent P.

Patent number: 4658207Abstract: A device for measuring the water content in small samples of an ink-water mixture. The sample is used as the dielectric for a capacitor cell which includes inner and outer concentric electrodes. The ink sample fills a gap between the electrodes, thereby controlling the total capacitance of the cell. The cell is connected as part of an oscillator circuit, the output frequency of which varies in a known manner with the dielectric constant of the ink mixture, which in turn is determined by the mixture's water content. A display is provided which varies with the frequency of the output signal, thereby indicating the sample's water content. A mechanism is provided for conveniently removing the inner electrode so that a sample can be introduced, and then returning the inner electrode so that the sample floods the gap between the two electrodes.Type: GrantFiled: March 28, 1985Date of Patent: April 14, 1987Assignee: Rockwell International CorporationInventors: Gino A.

Patent number: 4423623Abstract: A meter and a method are provided for measuring the composition and flow rate of a coal slurry and other similar mixtures. The meter is a waveguide through which the mixture flows. Microwaves are propagated in the waveguide from a transmitter probe. A detector probe spaced from the transmitter probe receives signals from the microwaves. Those signals are processed to determine a characteristic frequency of the waveguide or the wavelength of the propagating microwave, which are related to the composition of the mixture within the waveguide. A second transmitter and detector pair determines these properties for another portion of the waveguide. Differences in the frequencies resulting from inhomogenuities in the mixture are cross correlated to determine the flow rate of the mixture.Type: GrantFiled: August 24, 1981Date of Patent: January 3, 1984Assignee: Rockwell International CorporationInventors: William W. Ho, Alan B. Harker, Ira B. Goldberg, Kwang E. Chung
