A siphon tube assembly for papermaking dryer drums having a threaded rotary elbow connection between support and siphon tubes permitting the tubes to be selectively oriented by rotation of the elbow connection between an installation position wherein the tubes are in general alignment and an operative position wherein the tubes are angularly related. In a preferred embodiment, the siphon tube is braced in rigid engagement with the interior of the dryer drum for use as a rotating siphon, it being also contemplated that the present elbow joint may be embodied in stationary siphons. The elbow joint provides an operating keyway accessible through the interior of the support tube for manipulating rotation of the elbow joint without requiring the use of handholes or manholes in the dryer durm.

Articulable siphon tube assembly for dryer drum

A rotating joint for establishing supply and return fluid flow connections between stationary piping and a rotating drum and syphon pipe and in which separate bearings and seals are provided for a drum shaft and a syphon pipe.

Rotating joint with separated bearings and seals

An irrigation system having a generally vertical water delivery pipe and a water distribution pipe extending horizontally from and communicating with the delivery pipe. The distribution pipe is driven in rotation around an axis defined by the water delivery pipe by a hydraulic fluid operated drive, while hydraulic fluid for actuating the drive is circulated between the drive and a pump or the like through a conduit system which includes a rotary joint encircling the axis defined by the delivery pipe.

Irrigation system

A manually disengagable coupling for joining together fluid conduit portions for flow therethrough and a dishwasher incorporating such a coupling in a fluid conduit which has portions extending within a housing for enclosing dishes to be washed. By means of the manually disengagable coupling, portions of the fluid conduit may be removed from within the housing of the dishwasher for purposes of cleaning the dishwasher interior, while rotational and angular displacement between the joined conduit portions is resisted by characteristics of the coupling described more fully hereinafter.
