  • Noninvasive method and apparatus using coherent backscattering for process control
    Patent number: 5063301
    Abstract: A method and apparatus for the noninvasive real-time characterization of samples using coherent backscattering is disclosed. The sample is illuminated by a laser, and the radiation that is coherently backscattered is measured. The line width or line shape of the coherent backscattered radiation, or in some cases just the existence of coherent backscatter, is then used to characterize the sample under test. This characterization is then used for the real time control of a process acting upon the sample.

  • Tubular welded railing system
    Patent number: 5062732
    Abstract: A railing system is composed of vertically aligned metal tubes and cross-members which are metal tube rails. The posts are formed with round protruding bosses whose outer diameter (OD) is the same as the outer diameter of the posts. The rails also have the same outer diameter. The bosses and rail ends may be brought into roundness, so that they match in a smooth circumferential seam, by round plugs forced into the bosses and rail ends. The post-rail joints are then welded in a circumferential weld.

  • Leach resistant ink for protecting documents from alteration and document protected thereby
    Patent number: 5058925
    Abstract: An initially colorless, chemically sensitive protective ink which can be readily printed or applied onto a document substrate and which reacts upon contact with an oxidizing agent to form a noticeable color change is provided. The protective ink, when printed onto a document, resists leaching by water for an extended period of time, both before and after contact with oxidizing agents, and provides visible evidence of any attempted tampering. The leach-resistant ink includes a colorless material which becomes colored upon contact with an oxidizing agent and a complexing agent which reacts to form a complex with the colorless material. A fixing agent which promotes insolubilization and fixing of the complex to the document substrate is also provided.

  • Scroll apparatus with modified scroll profile
    Patent number: 5056336
    Abstract: In a scroll apparatus for fluid compression, two interfitting involute scroll elements with inner wall surfaces, each defined by an inner tip portion, an adjacent intermediate portion, an outwardly tending arcuate portion for periodic engagement in moving line contact with the inner tip of the other respective scroll element, and an involute portion extending from the arcuate portion to an outer end of the scroll element. When the involute scroll element inner tip is in moving line engagement with the arcuate portion of the other element, the scroll elements cooperates to define sealed final compression chambers of decreasing volume bounded by the intermediate portion of the scroll elements adjacent the respective inner tips, providing an extended duration of final compression as compared to a scroll apparatus having modified scroll elements.

  • Multilevel phase unbalance compressor motor protection system
    Patent number: 5058031
    Abstract: A method of protecting the compressor motor of a refrigeration system using a multiphase AC power source. The method comprises the steps of monitoring each phase of the power supply to the compressor motor; calculating the average phase for the phases of the AC power supply; determining a maximum phase unbalance deviation from the average phase; determining if a first level of phase unbalance protection is active; setting a system protection level as the first level of phase unbalance protection if the first level is active; setting the system protection level as a second higher level of phase unbalance protection if the first level is not active; and initiating a compressor motor shutdown if the system protection level is exceeded by the maximum unbalanced phase deviation.
