  • Patent number: 4577677
    Abstract: A method of operating a heat exchange system of the type adapted to receive a hot fluid and a cool fluid therethrough accomplishes cleaning of the system by terminating cool fluid flow to a portion of the system. Both fluids are passed through the entire system for a period of time. Flow of the cool fluid is then terminated to a portion of the system while continuous flow of the hot fluid is maintained through the entire system. Thus, the operating temperature of the entire system is increased so as to melt wax and other deposits on surfaces in the system.

  • Patent number: 4577908
    Abstract: A method for in situ processing of oil shale in which rubblized shale is removed from the retort and subsequently returned to the retort. A section of shale in a subterranean formation is first rubblized so as to form a retort chamber filled with rubble. The rubblized shale is then removed from the retort chamber, followed by crushing of the rubblized shale into shale particles of various sizes within an overall size range. Subsequent to the crushing step, the shale particles are separated according to size into a plurality of shale particle groups, each of which includes shale particles within a predetermined group size range. Each group size range makes up a portion of the overall size range. Substantially all of the shale particle groups are then sequentially reloaded into the retort chamber so that the particle groups are graded according to particle size within the chamber, wherein the largest particles are at bottom end of the chamber and the smallest particles are at the top end of the chamber.

  • Patent number: 4577492
    Abstract: A method and apparatus are provided for analysis of a sample of matter for multiple organic constituents and elemental sulfur in a single process. The method involves passage of a fluid sample through a first separations zone for retention of a first organic constituent, passage through a second separations zone for separation of the remaining organic constituents and sulfur, and quantitative determination of each constituent of interest including elemental sulfur.

  • Patent number: 4575414
    Abstract: An apparatus and method for mixing a fluidized solid and a fluid wherein the fluidized solid flows in a space defined between an outer member and an inner member positioned within the outer member. A body means is provided in the space between the members to occupy a predetermined volume in the space. A stream of solid particles flows around the body, and is directed across the upper end of the inner member. Fluid is released at the upper end of the inner member which mixes with the fluidized solid.

  • Patent number: 4568189
    Abstract: An apparatus and method for aligning a mask and wafer in the fabrication of ntegrated circuits utilizing alignment patterns on the mask and wafer. Each alignment pattern comprises a plurality of parallel alignment marks which are spaced from one another such that the patterns may be superimposed so that the marks of one pattern are positioned between marks of the other pattern. When the patterns are misaligned, a moire pattern is produced which disappears on alignment. The marks of each pattern are also disparately spaced from one another, permitting a gross to fine alignment. In aligning the patterns, each mark of one pattern is positioned between pairs of marks of the other pattern in an order corresponding to the widths of spaces defined between marks of the other pattern, progressing from the largest space width, giving gross alignment, to the smallest, giving fine alignment.

  • Patent number: 4567340
    Abstract: An apparatus and method for drying a solid material wherein the solid material is exposed to a radio frequency electromagnetic field such that water is expelled from the surface of the solid material as a liquid. The liquid water thus expelled is then collected.

  • Patent number: 4567582
    Abstract: The stacking velocity required for common midpoint stacking in three-dimensional seismic exploration is determined by determining the stacking velocity in three directions for a common midpoint. The magnitude of the thus determined stacking velocities in any three directions defines an ellipse centered at the common midpoint. The equation of the thus defined ellipse determines the stacking velocity in any direction about the common midpoint.

  • Patent number: 4555177
    Abstract: A method and apparatus for detecting the wavelength of singlet state resonance fluorescence of a sample, wherein the sample is illuminated sequentially with various incident wavelengths. For each wavelength, linearly polarized and circularly polarized components are allowed to pass sequentially by a first polarizer to the sample. The sample emits light as a result of spontaneous molecular energy transitions. Four components of the emitted light are allowed to sequentially pass to a detector by a second polarizer. The intensities of these components are then detected, and these values can be employed to obtain a new ratio for each wavelength. The wavelength at which this ratio equals one is selected as the wavelength of resonance fluorescence. In one example, a computer is provided to control the illumination of the sample and the two polarizers, and also may be utilized to compute the above ratios.
