Abstract: A gravity feeder for a liquor distribution system includes a manifold having a vented chamber, there being a series of vertically extending nipples on the manifold that are of different lengths. Interchangeable feeder caps detachably secured to individual bottles telescope over the manifold nipples to support the bottle in inverted position. Each feeder cap has a feeder tube that projects into the manifold chamber with its lower end at a level corresponding to the different lengths of the nipples themselves. A feeder system is established in which the bottles go on line in sequence. An uncomplicated and efficient system is provided.

Abstract: Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having helically ribbed or barbed nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. The ribs on the nipples on the coupling member are resilient and deform when inserted. The nipples have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular spaces between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution into these spaces and helically along the nipples. There are no appendages, cavities or pockets in which permeate or cleaning solution could be trapped.

Abstract: The present invention relates to a coupling useful for repairing broken or otherwise damaged tubing. More particularly the invention includes a coupling body member which accepts the cut ends of the tubing being repaired, a pair of washer-seals one for each tubing end and a pair of locking rams which drive the washer seals into the coupling body member and into an expanded fit thereby providing a secure fitting. The rams are threadably received into the coupling body member and locked thereon against unintentional reverse rotation.

Abstract: A method of recovering a heat-recoverable article onto a hollow substrate, the heat-recoverable article and the substrate each having at least one open end. The method comprises positioning the substrate between a rigid member and the heat-recoverable article, the substrate being positioned in the direction of recovery of the heat-recoverable article and at least part of the rigid member being in contact with the substrate. The heat-recoverable article is then treated to cause recovery thereof. The hollow substrates to which the method of the invention is applied are those which would be distorted if a heat-recoverable article were recovered onto them in the absence of a rigid member. Advantageously, the heat-recoverable article is a heat-shrinkable sleeve and in this case the rigid member is positioned inside the hollow substrate.

Abstract: A swivel joint and connection for abutting high pressure hydraulic manifolding, the joint comprising two flanged non-rotating swivel bodies with one of the non-rotating swivel bodies having a rotating swivel body journaled therein. A flanged tubular sleeve is secured between the adjacent end faces of the two non-rotating swivel bodies with the opposite ends of the tubular sleeve received respectively in counterbores formed in one non-rotating swivel body and in the rotating swivel body, respectively. A static annular seal is disposed between the first end of the tubular sleeve and the counterbore in the non-rotating swivel body and a dynamic annular seal is disposed between the end face of the opposite end of the tubular sleeve and the counterbore in the rotating swivel body. Improved composite elastomeric and metallic annular dynamic seals are also disclosed.

A resilient dynamic annular seal is disposed between an annular shoulder on the opposite end of the tubular sleeve and a first counterbore in the rotating swivel body.

Abstract: An improved heat fused pipe assembly joint is provided using an internally positioned fitting having an annular insert portion substantially the same diameter as the internal diameter of the pipe section to be joined and a shoulder portion having a larger diameter. The pipe section is joined to the fitting by heating the pipe end sufficiently to soften it, heating the insert portion of the fitting so as to soften its exterior wall, inserting the fitting so that the end edge of the pipe section substantially abuts the shoulder portion of the fitting and crimping to cause fusion of the pipe to the fitting. For additional strength, the fused pipe joint assembly may be provided with an externally positioned sleeve.

Abstract: Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having circularly barbed or serrated nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. Surrounding the joint thus formed is a flexible, elastomeric sealing sleeve. The nipples on the coupling member are axially slotted and have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular openings between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution without there being appendages, cavities, or pockets in which permeate or cleaning solution could be trapped.

Abstract: The invention relates to a pressure fluid coupling and in particular a high pressure hydraulic coupling. The coupling comprises two hollow flanged members, one of which carries a spigot having an O-ring near its end. The spigot is inserted into the bore of the other member and when it homes, the front faces of the flanges will abut. A resilient clip clips over the flanges to hold the coupling members together. Both coupling members may however be female members and a coupling device having "O"-rings near its ends may be inserted into the bores of coupling members.
