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.

An embodiment fluid recovery structure includes a body having an interior cavity, ports integrally joined to first walls of the body and having port walls that extend away from the body, with each of the ports having a port opening that is contiguous with the interior cavity, and a drain structure integrally joined to a second wall of the body and having a drain hole that extends from the interior cavity through the drain structure.

A nozzle cap spacer for a hydrant nozzle cap includes a substantially planar spacer body defining an outer body edge; and a resilient spacer spring arm extending from the outer body edge at a proximal arm end, the spacer spring arm configurable in an extended orientation and a compressed orientation, the spacer spring arm biased to the extended orientation; wherein, in the extended orientation, the nozzle cap spacer defines a substantially oblong shape, and in the compressed orientation, the nozzle cap spacer defines a substantially circular shape.

The disclosed technology includes a valve assembly having a valve, an actuating system, and a trigger. The trigger can be in mechanical communication with the actuating system and the actuating system can be in mechanical communication with the valve. The trigger can be positioned such that the trigger can interact with liquid resulting from a leak in a plumbing system, and upon interaction with liquid, the trigger can release the actuating system such that the actuating system can cause the valve to transition from an open position to a closed position. In the closed position, the valve can restrict the passage of liquid through the plumbing system such that the leak can be mitigated or stopped.

A drip chamber for an infusion tube that includes a first end arranged to receive a drip tube, a second end including an exit port, at least one wall connecting the first and second ends, a space enclosed by the first and second ends and the at least one wall, and first and second lenses each directly fixed to said at least one wall.

A gas-leak management system including a primary duct; and a leak-management duct, at least a portion of the leak-management duct surrounding at least a portion of the primary duct, wherein the leak-management duct includes a gap between the portion of the primary duct and the portion of the leak-management duct, and including one or more vent holes in fluid communication with the gap.

A nozzle cap spacer for a hydrant nozzle cap includes a spacer body defining an outer body edge, the spacer body defining a spacer body thickness; and a resilient first spacer spring arm extending from the outer body edge and biased away from the spacer body in an extended orientation, wherein the first spacer spring arm defines a first spring arm thickness; wherein the first spring arm thickness of the first spacer spring arm is equal to the spacer body thickness of the spacer body.

The present disclosure relates to a hydraulic component with a valve unit for a hydraulic system, and a hydraulic system having such a hydraulic component. The valve unit of the hydraulic component has a valve block and a valve piston. The valve piston is moveably along a first bore supported in the valve block. Further, the valve unit is admittable with pressurized hydraulic fluid and is configured such that the valve piston can be moved between a closed position and an open position. The hydraulic component according to the disclosure is particularly characterized in that the first bore is configured as a through-hole through the entire valve block and the hydraulic component has a collecting unit. The collecting unit at least partially surrounds the two end openings of the first bore and is configured collect and drain hydraulic fluid leaking out of the two end openings of the bore.

A leak preventing appliance and method for preventing liquid from leaking out of a damaged tank (2). The appliance comprises a suction head (4) to be pressed against an outer wall (5) of the tank under the effect of an underpressure generated by a vacuum pump (3). The suction head comprises a first chamber (6) and a second chamber (9) arranged around the first chamber. Each chamber has an opening (7, 10) intended to face said tank wall. The suction head is attachable to the tank wall under the effect of a reduced pressure produced in the second chamber by the vacuum pump. The first chamber is connectable to the vacuum pump via a valve device (8), which is configured to keep the first chamber connected to the vacuum pump when a reduced pressure produced in the second chamber by the vacuum pump is below a threshold value and to otherwise keep the first chamber disconnected from the vacuum pump.

Implementations described and claimed herein provide systems and methods for harvesting water from precipitation while limiting loss due to evaporation and sublimation. In one implementation, precipitation is received on a collection surface through an opening during a precipitation event. The received precipitation is sealed on the collection surface from an outside atmosphere using at least one cover assembly in response to a triggering event concluding the receipt of the precipitation. The at least one cover assembly includes a take-up assembly adapted to extend a cover from a first cross bar to a second cross bar over at least a portion of the opening. Water harvested from the sealed precipitation is directed to a water storage device. Other implementations described and claimed herein provide systems and methods for remote monitoring and management of water collection devices.
