A sprinkler configured for engagement with a coupling, the sprinkler including a raised lip end; and a distal end disposed opposite from the raised lip end, the sprinkler defining a raised lip between the distal end and the raised lip end, the sprinkler defining a groove between the raised lip and the distal end.

The present invention refers to a fluid connector for a battery pack of a vehicle, and to a battery pack for a vehicle. The fluid connector, with a main conduit and at least one connection conduit that protrudes from a first side of the main conduit, wherein a fluid flow path extends from the main conduit to and through the connection conduit, and wherein the fluid connector comprises a fastener with at least one latch device for fastening the fluid connector to the battery pack, the fastener being arranged at a second side of the main conduit, the second side being arranged opposite to the first side.

A pipe fitting has housing portions attached in spaced relation to define non-coaxial receptacles that receive pipe elements. The housing portions are supported on split rings received within grooves in each housing portion. The housing portions are supported in spaced relation in a preassembled state to permit insertion of pipe elements into the receptacles without disassembly of the fitting. The grooves in the housing portions have a floor surface with three surface portions. Two of the surface portions on each groove of each housing portion engage the split rings when the housing portions are supported in spaced relation.

A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.

An apparatus for the separation or liquefaction of a gas at cryogenic temperatures which comprises an isolated chamber comprises at least one front distillation column operating at cryogenic temperatures and also a pipe for transferring fluid coming from or going to the column, the pipe having a diameter D comprising a bend for changing the direction of flow of the fluid, with profiled deflector vanes placed inside the bend, with their concavity towards the centre of the bend forming a plurality of ducts.

An unmachined cast body for a pipe fitting, the cast body includes a first body end and a second body end disposed opposite from the first body end, the cast body defining an axis extending from the first body end to the second body end, the cast body defining a midpoint between first body end and the second body end, a centerline of the cast body defined at the midpoint perpendicular to the axis, a first distance from the centerline to the first body end being equal to a second distance from the centerline to the second body end, an inner body surface defining a fitting bore extending through the cast body from the first body end to the second body end, and an outer body surface spaced from the inner body surface, the outer body surface defining a first frustoconical shape and a second frustoconical shape.

A method for using a pre-assembled coupling assembly, the method including providing a pipe fitting defining an inner end and an outer end, the pipe fitting defining an axis; axially inserting the inner end of the pipe fitting into a gasket, a portion of the pipe fitting within the gasket positioned radially outward from a portion of the gasket; and assembling a housing around the gasket, the housing and the gasket forming a coupling, the coupling retained on the inner end of the pipe fitting when the coupling is in a relaxed position.

An impact reducer for drainage stacks includes a first pipe section with a first internal passage having at least five alternating bends along its longitudinal axis, a bypass vent in a second pipe section having a second internal passage parallel to the longitudinal axis and a clean out plug in a third pipe section having a third internal passage at a radial angle with the longitudinal axis. First and second end fittings are located on the impact reducer for connecting the device to a drainage pipe. The impact reducer adjusts the turbulent flow of water falling in the drainage stack, converting the turbulent flow to laminar flow before the lower bend fitting of the drainage stack, which protects the lower bend fitting from impact shock.
