  • Patent number: 10495182
    Abstract: An apparatus for an air turbine starter for an engine. The air turbine starter includes a housing defining an inlet, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of gas there through. A turbine member is journaled within the housing and disposed within the flow path for rotatably extracting mechanical power from the flow of gas and having a turbine output shaft. The air turbine starter further includes a planetary gear system drivingly coupled with the turbine output shaft and including a sun gear, a ring gear mounted to the housing, and a set of planetary gears operably coupling the sun gear and the ring gear with the sun gear is coupled to the turbine output shaft.
    Type: Grant

  • Publication number: 20150211746
    Abstract: A cooking accessory frame may include a base component and an upper component. In certain embodiments, the base component and upper component may be ring shaped. The upper component may attach to the base component, and in certain embodiments, by a plurality of support struts. A heat diffuser plate may attach to the upper component. In certain embodiments, the heat diffuser plate may include a main plate section and a plurality of spokes. One end of the plurality of spokes may attach to an inner surface of the upper component, and another end of the plurality of spokes may attach to the main plate section. The cooking accessory frame may be placed in between a heat source and a cooking vessel to provide distance from the heat and to allow for the heat to spread along the bottom of the cooking vessel for a more even cooking experience.

  • Patent number: 5354790
    Abstract: A method is disclosed for the preparation of non-stringy hydrogels that are comprised of a homogeneous uniform mixture of water and at least one water-soluble high molecular weight polymer. Suitable mixtures may be derived from poly(ethylene oxide) and water or poly(vinyl pyrrolidone), a viscosity enhancing hydrophilic polymer and water, and further, may optionally contain an effective amount of a water-soluble electrolyte to provide conductive non-stringy materials. These polymeric mixtures are crosslinked by exposure to radiant energy to provide gel-like solids which are sufficiently tacky and adhesive to adhere to the subjects' skin and yet are substantially non-stringy and non-aggressive such that contact with such hydrogels imparts less discomfort to the user. In addition, the consumer utilizing the products of this invention would not experience the objectionable sticky, stringy sensation associated with existing adhesive gels.

  • Patent number: 5225236
    Abstract: The present invention describes a protective drape and methods for using the drape to protect or shield an object against the harmful effects of accidental exposure to optical radiation, electrical discharge, heat, or an open flame. The present invention comprises a flexible solid sheet and a composite scrim and includes methods for predicting/determining the suitability of a chosen metallic component for use in the instant drape.

  • Patent number: 4989607
    Abstract: The highly conductive hydrogels of this invention are comprised of a cohesive uniform mixture of poly(vinyl pyrrolidone), a viscosity-enhancing hydrophilic polymer, and an effective amount of an electrolyte. This polymeric mixture which is crosslinked by exposure to radiant energy provides a gel-like solid which is sufficiently tacky and adhesive to adhere to the subjects' skin and yet is substantially non-stringy and non-aggressive such that the use of such hydrogel imparts less discomfort to the user. In addition, the consumer utilizing the product of this invention would not experience the objectionable sticky, stringy sensation associated with existing conductive adhesive gels.
