  • Patent number: 10750749
    Abstract: This invention relates to a process and an aqueous composition for killing spores. The process comprises contacting the spores with the aqueous composition for a sufficient period of time to effect a desired reduction (e.g., at least a 4 log reduction) in the number of spores capable of reproduction, metabolism and/or growth. The aqueous composition comprises water, peracetic acid and hydrogen peroxide. The concentration of peracetic acid in the water may be in the range from about 0.001 to about 60% by weight, or from about 0.001 to about 0.5% by weight.

  • Publication number: 20200261609
    Abstract: A method for pressurizing a sterilization chamber of a steam sterilizer with a controlled rate of pressure change. Pressure is increased in the sterilization chamber by opening a steam-to-chamber valve for a pulse duration during each of a plurality of time PERIODS needed to reach a target pressure value. During each time PERIOD, the steam-to-chamber valve is moved to an open state for the duration of the pulse. An error value indicative of the difference between a Theoretical Pressure and a Measured Pressure is determined at the end of each PERIOD. This error value is used to determine the duration of the pulse for the subsequent PERIOD, thereby maintaining a desired rate of pressure change in the sterilization chamber.

  • Patent number: 10591006
    Abstract: A brake assembly for braking relative rotational movement of a spindle that is moveable about a central axis relative to a hub. The brake assembly is comprised of a collar comprised of a pair of arcuate leg sections, having a first end pivotally linked together to allow pivoting movement of the leg sections. A frictional surface is provided along the inner surface of each of leg section. An adjustable fastening assembly connects second ends of the leg sections together and clamps the leg sections to the spindle with the frictional surface on the leg sections engaging the outer surface of the spindle. A stop member is connected to the hub and is disposed to engage a surface of the leg sections, wherein rotation of the spindle in a first direction about the axis causes a surface of one of the leg sections to engage the stop and to reduce frictional engagement of one of said leg sections by releasing engagement with the spindle as the spindle moves in said first direction.

  • Patent number: 10473172
    Abstract: A brake screw for use with a surgical lighting system. The brake screw includes a screw member retained within a threaded aperture of a mounting hub of a spindle of an arm used with the lighting system. The screw member is rotationally adjusted to enable displacement in an axial direction. A brake member is in axial alignment with the screw member and disposed for movement in the axial direction against a mounting tube retained within the mounting hub upon rotational adjustment of the screw member. A rivet section is integrally formed with the brake member and has a distal end retained within an axial recess formed within the screw member, allowing movement of the brake member in the axial direction within the screw member. A bias member is disposed between the screw member and the brake member to create a biasing force that urges apart the screw member and the brake member along the axial direction.
