Abstract: A loading arm having dual inboard and outboard arms and dual connections for connecting the arm to a tank in which provision is made for the loading arm to be connected to side-by-side flanges on the tank and to provide for movement of the connecting system in three mutually perpendicular planes relative to the outboard arm of the loading arm.

Abstract: The recovery of a hydrocarbon capable of autopolymerization from an air stream by absorbing the hydrocarbon with a plasticizer and separating the hydrocarbon from the plasticizer by vacuum and atmospheric distillation.

Abstract: Method and apparatus for handling and deforming a relatively short workpiece, such as the upsetting of a pipe to increase the wall thickness at an end thereof in preparation for forming the threads of a pup joint.

Abstract: A method for testing a treated metal substrate toward its propensity to receive and adherently retain a finish coat such as paint or the like; the test is made before the finish coat is applied by applying a strip of adhesive to a specimen treated substrate, stripping the tape, and then comparing the amount of "soil" pick-up versus an established standard; "soil" includes any of the treating material picked up by the tape from the treated substrate.

Abstract: A tube joint including a male end which has a rounded inner edge having its original surface finish and a female end which is expanded to receive the male end. The male end is formed by chamfering the end outer diameter and flaring the end inner diameter until the end inner diameter is substantially rounded. The female end is expanded so its inner diameter is only slightly greater than the outer diameter of the male end.

Abstract: Low alloy high strength titanium steel and a process for preparing said steel by solution heat treating and thereafter controlling the cooling rate to the precipitation hardening temperature range required to produce a steel characterized by a yield strength in the range of 60,000 to 120,000 psi and/or by a bendability characteristic demonstrable by a capability of being bent through an arc without cracking to an inside diameter equal to the thickness of the product.

Abstract: The coupling disclosed is for attachment to a loading arm and permits attachment of the loading arm to flanges of different diameters by providing adapters which are releasably secured to the coupler. A different size adapter is utilized for each different size flange that the coupler is to be fastened to. The clamp arms move radially outward from the flowway through the coupler to accommodate larger size adapters which fit with larger size flanges to which the coupling is to be attached.

Abstract: Method and apparatus for processing continuous strand material in a continuous processing line wherein movement of the strand is continued at a subsequent processing station despite halting movement of the strand at a preceding station and for providing an indication of when the portion of the strand present at the preceding station when halted reaches the subsequent processing station or position.

Abstract: A flexible crack-resistant and chemically resistant thermosetting vinyl ester resin is produced by co-reacting an epoxy resin, a carboxyl terminated elastomer and an unsaturated monocarboxylic acid, such as acrylic or methacrylic acid. The neat resin is miscible and copolymerizable with ethylenically unsaturated monomers such as styrene. A novel cast pipe utilizes the resin of the invention as an unreinforced crack-resistant inner lining. This abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

Abstract: A high strength low alloy titanium, cold reduced flat rolled steel product with yield strengths in excess of 120 and as high as at least 180 ksi and process for producing the same.

Abstract: Energy measuring systems particularly adapted for use in conjunction with load moving devices which comprise apparatus for measuring and providing an indication of the energy expended in moving a load, and for converting a signal corresponding to such energy to a signal corresponding to the weight of the load.

Abstract: A pipe reeling machine guide for guiding and burnishing an external surface of a pipe having a work contact surface of a composition consisting essentially, in percent by weight, of: 0.70-0.90 carbon, up to 1.75 manganese, 0.08 max. phosphorus, 0.08 max. sulfur, 0.5-1.75 silicon, 8-12.0 nickel, 23-27 choromium, and the balance being essentially iron with residual impurities.

Abstract: An epoxy composition including an epoxy resin, an aromatic amine which is used in an amount which is substantially the stoichiometric amount sufficient to react with the epoxy groups of the epoxy resin, a clay filler, and a material provided to extend the shelf life the composition which material has a composition as follows: ##STR1## and wherein R may be hydrogen or an organic radical and preferably where said material is selected from a group consisting of imidazole, 1-methyl imidazole, 2-ethyl imidazole, 1-vinyl imidazole, and 2-ethyl 4-methyl imidazole with such material being in the range of from 0.2% to 12% by weight of the clay filler or in the range from 0.06% to 3.30% by weight of the total composition.

Abstract: A laminate tube structure produced by stretch reducing, in combination, a pair of tubes. The resultant tube structure is particularly adapted for use as a mandrel for supporting a piercing point of a seamless-tube mill.

Abstract: Method of making a plastic pipe and method of making same, having an outer shell of reinforced thermo-setting resin and an inner shell of thermo-setting and thermo-plastic resins.

Abstract: A heat treatment of nine percent nickel steel including carburizing, double normalizing, tempering, subcooling and then tempering to provide a steel having useful mechanical properties at extremely low temperatures.

Abstract: Process for producing refined steel including the provision of molten iron, adding molten steel to said molten iron to provide a molten mix, adding iron bearing material in unmolten form to said mix, and refining the mixture by blowing essentially pure oxygen therethrough.

Abstract: A tree harvester in which the tree is engaged by an articulating boom, felled by a fell shear on the boom and fed into a buck shear on the machine which bucks the tree into sections which are stored in a sling on the machine. After the sling is filled, the machine deposits the sections at a pickup location.
