The invention relates to a protective valve ring (1) for an oxygen gas cylinder (3). The protective valve ring (1) comprises a body (4) adapted to enclose an outlet (5) of a cylinder valve (2). The body (2) comprises an incombustible and heat absorbing material, and has an internal shaping adapted to guide any potential oxygen gas leak away from inflammable parts of the gas cylinder (3). The invention also relates to a shut-off valve (2) for controlling flow of a pressurised gas and a method for attaching a protective valve ring (1) to a shut-off valve (2) of an oxygen gas cylinder (3).

An apparatus comprising an inner ferrule and an outer ferrule. The inner ferrule comprises a plurality of engagement sections that define a plurality of gaps between the plurality of engagement sections. The outer ferrule is disposed around at least a portion of the inner ferrule. The outer ferrule comprises an engagement area mechanically joined to the plurality of engagement sections to join the inner ferrule to the outer ferrule.

An automated fluid transfer system and method allows a person to pour fluid, such as used motor oil, into a collection pan which automatically pumps the fluid to a bulk storage tank, without secondary containment in the collection pan. The system utilizes an air powered pump, thereby eliminating the use of electricity which creates fire and explosion hazards. A float rises and falls in response to fluid in the pan, so as to automatically turn on and turn off the pump. An alternative manual mode is provided to allow fluid to be sucked by the pump from a container directly into the bulk storage tank, while bypassing the collection pan.

A booster-ejector system captures and recycles leakage fluids from a process. When a pressure differential (head) of the process is above a threshold value, an ejector system uses motive fluid from a process high-pressure (HP) region to entrain and compress the leakage fluid, and direct it to a low pressure (LP) region. When the head is below the threshold value, a controller reconfigures a plumbing system and activates a leakage pump to pump the leakage fluid to the LP region. The system can include only one ejector, or a plurality thereof, which can be coupled such that the diffuser output of each ejector is directed to the suction input of the next ejector. At least one of the ejectors can include an exchangeable throat, which can impart a rotational component to the fluid. The HP and LP regions can be the output and input, respectively, of a compressor.

Example aspects of a nozzle cap spacer for a hydrant nozzle cap, a spaced nozzle cap assembly, and a method for adjusting a rotational indexing of a nozzle cap are disclosed. The nozzle cap spacer for a hydrant nozzle cap can comprise a spacer body defining an outer body edge; and a resilient first spacer spring arm extending from the outer body edge, wherein the first spacer spring arm is biased away from the spacer body in an extended orientation.

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 apparatus for collecting liquid leaks, the apparatus comprising a tub, at least one boot for sealing a pipe passing through the tub for preventing leakage of the tub from water leakage collected in the tub from either a fluid reservoir disposed above the tub or leakage dripping along the pipe.

A floor protection apparatus for use under parked snowmobiles or the like. The apparatus features a mat having longitudinally opposing first and second ends, and laterally opposing first and second sides. Longitudinally channeled areas reside respectively adjacent the sides of the mat at a topside thereof, and each feature a set of longitudinally running channels separated from one another by longitudinal ribs. One or more collection areas reside between the channeled areas at the topside of the mat and are of recessed elevation relative to the longitudinal ribs. A laterally ribbed central area resides between the first and second channeled areas and comprising a series of lateral ribs spaced from one another in the longitudinal direction. The mat is assembled from sections that fastened together through raised, abutted boundary edges.
