Abstract: Seal means for communicating, aligned passages in telescoping insert and socket parts of an underwater connector for hydraulic lines. A seal means carrier, interposed between the parts, has a passageway aligned with and connecting the mentioned passages. An annular resilient seal ring fits snugly within and about the passageway and has opposite edge portions which, in the assembly of the connector, sealingly engage the surface portions of the insert and socket about said passages.

Abstract: A refractive block of ceramic material as a burner block or the like for furnace walls, is provided with a surrounding rib with recesses. A frame of suitably rigid and refractive angle bars encompasses the block and receives bolts extending transversely through the recesses and into or through the furnace wall. The bolts are anchored in both the frame and furnace wall and bear against the block inner face for securing the block in position, avoiding the danger of spawling or breaking out the block.

Abstract: A method of salt grinding of pigments wherein the material to be ground is milled with a salt, an organic conditioner, and larger particles such as balls, nails, or in a strong kneader for comminuting the pigment to the desired state of subdivision. This grinding mass is made into a smooth flowing suspension by addition of more organic conditioning agent rather than solvents, as heretofore. The suspension is then passed through a decanter type centrifuge resulting in a sediment fraction containing most of the salt, some pigment, and some organic conditioning agent, and a liquid fraction containing most of the pigment, some salt and conditioning agent. The sediment portion is returned to the grinding mechanism where it is combined with a new batch of unmilled pigment for a subsequent milling cycle, while the pigment is separated by filtration from the liquid portion after some addition of water and flocculating agents. The filtration and wash liquors are combined.

Abstract: A method of salt grinding pigments wherein the material to be ground is milled with an inorganic salt, an organic conditioner, and larger particles such as balls or nails for comminuting the pigment to the desired state of subdivision and is subsequently recovered from the ground mass wherein the mass is treated after grinding with an organic liquid which is a solvent for the organic conditioner but which is inert to the pigment and to the inorganic grinding aid. The dispersion resulting is then centrifuged to remove solids constituting over-size pigment and inorganic grinding aid without separating the dispersed pigment particles of desired state of subdivision. The sediment is removed from the liquid dispersion of pigments and the liquid is subsequently separated from the dispersed pigment as by filtering or other appropriate means.

Abstract: Module reclaim apparatus comprising a housing open at the bottom and an end and movable over a stack of seed cotton or other fibrous modules. The housing carries a descending series of pronged feeder rollers near one end which release fibers from the adjacent end of the module and throw same onto a transversely traveling conveyor for ultimate delivery, for instance, to the gin equipment. A rotary sweeper returns escaped fibers to the feeder rollers and a novel jacking system provides for adjusting the vertical positioning and levelling of the housing. A door at the forward end of the housing moves against the rear end of the module when the fibrous remnant is too thin to be self-supporting.

Abstract: A submersible large diameter pipe swivel is provided with seal means which is designed and adapted to allow small radial and axial relative movements (wobble) between the pipe and the swivel joint, while maintaining full integrity of the seal and which, being unaffected by such wobble, therefore offers minimum resistance to rotation.

Abstract: Multiple sets of rotary impeller blades and an atomizing screen are located in the path of gas containing fluid, as drilling mud, discharged from a rotary body through a suction degassing chamber, for the purpose of more fully separating the gas from liquid constituents.

Abstract: A single anchor leg mooring and tanker cargo transfer system has a base with an anchor leg pipe shaft having a horizontally swiveling housing thereon to which are attached vertically pivoting cargo hose arms. The arms have widely spaced, parallel portions extending a substantial distance beyond the base portion for augmenting the torque applied to the swivels by the cargo hoses. The hose arms are stabilized and limited in their vertical pivoting by a balanced lever structure pivotally mounted on the base and carrying buoyancy tanks. Bumpers limit the vertical pivoting of the lever structure flexing of the hose arms secured thereto.

Abstract: Liquid treating apparatus, for instance, a degasser for contaminated drilling mud returned from a well, comprising a treating chamber in which liquid to be treated is subjected to a suction source. A centrifugal impeller is rotatably mounted immediately adjacent the suction source communication with the chamber for repelling liquid droplets tending to enter the suction source, while admitting gaseous matter into the suction source.

Abstract: A drilling mud degasser apparatus which has only a single moving part, namely, a unitary, hollow body rotatable within an open bottom casing, and the impeller of a suction pump connected to the interior of the rotor body. The casing and rotor are submerged in a pond of mud returned from a well or connected in a return mud line such that gas-cut mud entering the bottom of the rotor body is centrifugally thrown upwardly and outwardly to cause the liquid and/or sand components to travel up the wall of the rotor body and be discharged through outlet openings at the top of the body wall. Concurrently, released gases are drawn through inner gas outlets, at the top of the rotor body into the impeller housing and thence discharged. Differential discharge of sand and liquid components by centrifugal action may be provided as may a flotation collar for insuring uniform submersion of the casing beneath the liquid level.

Abstract: Wrapping sheets are propelled across the opposed platens of a baling press. After compression, the press box is removed from the bale, and thereafter wrapper folding members move along the bale walls to fold the freed edge portions of the wrapping sheets thereagainst. Finally, while the folds are held, securing bands are applied about the bale which is then released and removed.

Abstract: A method of dry cleaning fabrics, for instance, draperies or clothing, in situ, by forcefully infusing the fabric in the open atmosphere with special fast-acting, versatile dry cleaning solvent so as to dissolve and suspend various stains and soils in the fabric, even though firmly set due to age, and promptly drawing ambient air and droplets of soil-laden solvent by suction into a closed waste and suction chamber where the soil is deposited in the form of a sludge, while the carrier air and solvent is discharged to the atmosphere. A special, highly effective, fast-acting, nonflammable and nontoxic solvent is provided.

Abstract: A cleaning device for heat exchanger tubes comprising a rubbing body consisting of a hollow casing member of elastomeric material with diametrical openings, and an encased check ball. A thickened band extends intermediately around the casing member for rubbing against the tube wall and is provided with slots enhancing the flexibility of the band. The overall density of the device approximates that of the liquid with which it is to be used.

Abstract: A single anchor leg type single point mooring and cargo transfer buoy has a load-carrying central shaft pipe for anchoring on the sea bottom and having a plurality of structurally segregated transfer chambers about which rotatable housings are sealingly mounted. Cargo vessel piping connects with these rotatable housings which communicate with the sea floor piping through connections extending longitudinally through the central shaft pipe and through apertures in the central shaft pipe wall.
