  • Publication number: 20190187461
    Abstract: An electromagnetic beam scanning system and corresponding method of use is provided. The system includes a motor, a reciprocating mechanism, and a focus optic. The motor is configured to generate a rotational movement. The reciprocating mechanism is operatively coupled with the motor and configured to convert the rotational movement to a reciprocating movement including a plurality of strokes along a first scanned axis. The reciprocating movement has a constant speed over a portion of at least one stroke of the plurality of strokes. The focus optic is operatively coupled to the reciprocating mechanism such that the focus optic moves experiences the reciprocating movement of the reciprocating mechanism. The focus optic is configured to focus an electromagnetic radiation (EMR) beam incident upon the focus optic to a focus along an optical axis substantially orthogonal to the first scanned axis.

  • Publication number: 20150362217
    Abstract: In a wood pellet fueled forced hot air heating system, a burner is regulated in response to an ambient air, or supply plenum, temperature. The burner regulating means allows for increased burner cycle times. The air handler is regulated in response to a space to be heated, or room, temperature, typically through the use of a mechanical thermostat. The air handler regulating means when used in conjunction with the burner regulating means allows for immediate heat response during a heat call.

  • Publication number: 20070167585
    Abstract: An ethylene polymerization process is disclosed. Ethylene is polymerized in two slurry reaction zones with a C6-C10 alpha-olefin in the presence of a single-site catalyst capable of making a high molecular weight polyolefin. The process yields medium density and linear low density polyethylene having a bimodal molecular weight distribution and a melt index from about 0.10 to about 0.80. Films from the polyethylene have superior impact properties.

  • Publication number: 20070055021
    Abstract: Disclosed is a polyethylene composition. The composition comprises single-site multimodal resin A and single-site multimodal resin B, wherein resin A differs from resin B in molecular weight, in monomeric composition, in density, in long chain branch concentration or distribution, or in combinations thereof. Disclosed is also a method for making the polyethylene composition. The method comprises polymerizing, in the presence of two or more single-site catalysts, ethylene or its mixture with a C3-C10 ?-olefin to form a first multimodal resin and continuing the polymerization in the presence of the same catalysts but in a different hydrogen concentration, in a different monomer composition, or at a different temperature to form a second multimodal resin.

  • Patent number: 7041869
    Abstract: The present invention provides a transgenic animal expressing the reporter gene, luciferase, driven by a promoter (e.g. the E2F1 promoter) that acts as a sensor of cell cycle. The luciferase substrate, luciferin, emits light when metabolized, and the light is transmitted through mammalian tissues. Therefore, the transgenic animal model of the present invention allows for monitoring of areas of major cell cycle activity, a characteristic of cancer cells, under adequate visualization conditions. These transgenic animals are useful as in vivo models for testing preventative measures for cancer as well as for testing novel therapeutic modalities.

  • Publication number: 20050032641
    Abstract: A hydrogen storage material having improved hydrogen absorbtion and desorption kinetics is provided by adding graphite to a complex hydride such as a metal-doped alanate, i.e., NaAlH4. The incorporation of graphite into the complex hydride significantly enhances the rate of hydrogen absorbtion and desorption and lowers the desorption temperature needed to release stored hydrogen.

  • Patent number: 6771565
    Abstract: A boomer for generating acoustic signals in a marine seismic survey has a frame towed by a survey vessel. A coil is mounted to the frame and a conductive plate is adjacent to the coil. A capacitor is mounted to the frame, and control electronics system delivers an electric charge stored in the capacitor to the coil. The invention obviates the need for heavy conductive cables between the survey vessel and the boomer in conventional systems where the capacitors are carried by the vessel, while maintaining the desirable acoustic properties of the boomer.
