  • Publication number: 20190346060
    Abstract: A fluid collection and disposal device for a transfer cart used for transporting wet articles is comprised of a tray disposed below articles to be transported on a transfer cart. The tray has a drain opening. A conduit extends from the drain opening to an exterior side of the transfer cart. A valve assembly is connected to the conduit for controlling fluid flow through the conduit. The valve assembly is comprised of a valve element moveable between a closed, first position restricting flow of fluid through the conduit and an opened, second position allowing flow of fluid through the conduit. An actuator is provided for moving the valve element from the closed position to the open position. The actuator is moveable by physical engagement with an external stop.

  • Patent number: 9827600
    Abstract: A movable rack assembly for a washer having a generally rectangular frame. The frame includes a central hub connectable to a fluid source. A plurality of elongated tubular base members extends from the central hub and defines a bottom of the frame. A pair of spaced-apart elongated, tubular side members defines side portions of the frame and a space therebetween. Each of a plurality of spaced-apart transverse members has ends that are connected to one of the side members. The transverse members transverse the space defined between the side members. A rotary spray arm is attached to each of the transverse members. A plurality of corner spray nozzles on the frame directs fluid toward corners of the frame. The bottom members, the side members and the transverse members are fluidly connected with each other and fluidly connect the rotary spray arms and the corner spray nozzles with the central hub.

  • Patent number: 9726652
    Abstract: A chemical indicator device for use in detecting exposure to an oxidizing agent, such as hydrogen peroxide, comprising a substrate or support upon which is disposed a chemical indicator composition (ink) for detecting an oxidizing agent, such as hydrogen peroxide. The chemical indicator composition further comprises an indicator dye that achieves a distinct range of different color changes with clear transitions between colors, upon exposure to different doses of the oxidizing agent, thus allowing for both a qualitative and semi-quantitative assessment of exposure to the agent.
