  • Patent number: 10605272
    Abstract: A siphon elbow for pivotally connecting a first pipe and a second pipe in fluid communication. A first elongated body has a bore extending therethrough and a partially spherical indentation within the bore. A second elongated body has a bore extending therethrough and a generally spherical extension on a first end that pivotally engages the partially spherical indentation of the first elongated body. An internal locking system is disposed in at least one of the bores and locks the second elongated body into an operating configuration in which an angle formed between the first elongated body and the second elongated body is less than 180-degrees. Pivoting of the second elongated body from an installation configuration in which the angle is approximately 180-degrees to the operating configuration activates the internal locking system.

  • Publication number: 20040239111
    Abstract: Normally, compressed air coupling plugs lock inside a coupling housing. Decoupling must consequently occur by releasing said plugs counter to the friction forces existing between the plug and the housing. This requires force and the plug may not relieved of pressure when decoupled. The invention works with a locking element (2) which is mounted in a coupling housing (1). The plug (5) and the locking element (2) are provided with reciprocally corresponding locking means (24, 52; 28, 56) whereby the locking element (2) can be pivoted for decoupling without the plug (5) pressing on the housing (1), thereby enabling large caliber tubing, such as those used with construction compressors, to be coupled by hand without tools.

    Abstract: A coupling apparatus couples a container of colorant to a feeder structure for a polymer processing machine. The coupling apparatus includes a tubular structure with an outlet portion that engages the feeder structure, and an inlet portion that receives and supports the container above the outlet portion. The inlet portion has an upright position in which it supports the container in an overturned position from which the colorant can flow out of the container under the force of gravity. A joint, which is preferably a hinge, supports the inlet portion for movement to an overturned position. The inlet portion can then receive the container in an upright position from which the colorant will not spill from the container. Preferably, a releaseable locking device interacts with the joint to retain the inlet portion of the tubular structure releaseably in its upright position.

The upper and lower sections of the exhaust pipe are hinged together by a stiff joint, e.g., a spring-loaded hinged friction joint, and are positioned in line with one another with a slight gap between them. The lower section is double walled, and the inner wall extends somewhat up into the upper section. The upper section is single walled, with its wall aligned with the outer wall of the lower section. Air is drawn into the space between the inner and outer walls at the base of the lower section and also at a gap at the joint between the upper and lower sections. This air is drawn in both due to the aspiration caused by the higher speed exhaust flow through the inner exhaust pipe, and due to thermal rising of heated air.

The downcomer nevertheless folds when the header is to be raised for inspection or servicing. The folding axis is external of the downcomer, which breaks open as the folding action starts. In one form the header is straight while initially raised, hanging from a first hoist cable, and then as the lower section is raised further by a second cable the upper section is allowed to fold over. In another form, the folding progresses as the structure is raised, the upper section being hinged to the air supply fitting.
