Abstract: A quick connect-disconnect pipe coupling especially suitable for fiberglass pipelines including a male adaptor having a split ring located in a groove machined therein and bonded to one end of a pipeline. The split ring is held in the contracted position in the groove by means of a pair of restraining pins. A female sleeve is provided for receiving the male adaptor. The male adaptor is inserted into the female section, whereupon the wall of the female section "knocks out" the pins in the male section allowing the split ring to expand to its natural position and fits closely in a groove provided in the internal surface of the female section.For disconnect the split ring is compressed by inserting a tool through the wall of the female section to recompress and close the split ring and reinserting the restraining pins. The female section is then slid over the male section.

Abstract: A continuous process for the selective absorption of hydrogen sulfide from a feed gas comprising an acid gas mixture of carbon dioxide and hydrogen sulfide is provided which comprises counter-currently contacting the feed gas with an aqueous alkanolamine solution in an absorption zone having from two to ten separate stages, contacting the feed gas in each stage with lean aqueous alkanolamine solution and withdrawing rich aqueous alkanolamine solution from the bottom of each stage, in each stage maximizing the equilibrium approach between the hydrogen sulfide in the gas and liquid phases and minimizing the equilibrium approach between the carbon dioxide in the gas and liquid phases, and maintaining the rich solution loading in each stage within the range from about 0.1 to about 0.3 mole of acid gas per mole of alkanolamine. The absorption zone is operated in combination with a stripping zone to which rich aqueous alkanolamine solution is passed and in which lean solution is generated.

Apparatus features a workpiece spindle carrying member mounted on a base, a plurality of workpiece spindles mounted on the carrying member, means for rotating the carrying member and other means for rotating the workpiece spindles, means correlating the speed and direction of rotation of the carrying member and the workpiece spindles.Method includes the steps of depositing coating material on the workpiece as the parts translate and rotate past a device for depositing coating material.

Abstract: A continuous process for acid gas removal such as the removal of carbon dioxide, from a feed mixture of process gas and acid gas which comprises introducing the gaseous feed mixture to an absorption zone at an absorption zone inlet temperature in the range of about 35.degree. C. to 150.degree. C., treating the gaseous feed mixture in the absorption zone with an aqueous solution of alkanolamine under specified conditions, the absorption zone inlet temperature for the solution being in the range of about 30.degree. C. to about 75.degree. C., passing the aqueous solution of alkanolamine having acid gas absorbed therein to a stripping zone at an inlet temperature essentially the same as the absorption zone outlet temperature for said solution, removing solution from the bottom of the stripping zone at a bottoms outlet temperature in the range of about 100.degree. C. to about 150.degree. C.

Abstract: Apparatus including a tubular outer member having a baffle plate positioned therein downstream from the point of injection of gas into said tubular outer member. The baffle plate contains vanes for directing gas spirally to the inner walls of the pipeline to be cleaned. Abrasive material, usually sand, is introduced into the device through a line passing through the center of the baffle plate secured thereto so that the line and the baffle plate may be removed from the tubular outer member as a unit.

Abstract: A system of pressure gauges and pipeline arrangement is described for metering abrasive materials into a gas stream for subsequent injection into a pipeline to be cleaned.

Abstract: A gas actuated starting rod feed device for use with hand holdable oxygen cutting and/or scarfing torches. The starting rod feed device includes means for gripping and advancing a starting rod. The gripping means is operated in response to the stroke of a piston-like member which is actuated by a pulse of oxygen diverted from the main oxygen stream. The oxygen gas is vented to atmosphere at the end of the piston stroke so that the starting rod feed device is automatically reset and so that there is no pressurized oxygen present during the cutting or scarfing operation in the vicinity of the flame issuing from the torch.

Abstract: A method and apparatus for making an instantaneous thermochemical start on the surface of a metal workpiece.The method resides in the use of laser beam focused to a small spot to bring the ferrous workpiece to ignition temperature in combination with a high intensity oxygen jet to cause the initiation of the thermochemical reaction. The laser beam may impinge the workpiece at a point about 1 cm behind the spot where the oxygen impinges the workpiece surface to a point about 10 cm ahead of such spot. Accordingly, the laser beam may penetrate the high intensity oxygen jet and still cause the thermochemical reaction to start instantaneously.The apparatus resides in a scarfing machine having a scarfing nozzle, an oxygen spreader nozzle and a laser assembly associated therewith. The oxygen spreader nozzle is mounted so as to provide high intensity oxygen jet on the surface of the workpiece ahead of the scarfing oxygen effluent from the scarfing nozzle.

Abstract: A drive chuck having split sleeves moveably mounted on pins which slide/roll in slots in end members (flanges) so rotation of said chuck will urge said sleeves radially outward to engage the inside surface of a tube.

Abstract: A mercury vapor lamp is rendered substantially independent of the thermal environment by connecting each sealed end to a heat sink which is maintained at below 100.degree.C and located sufficiently close to the sealed ends to hold the seal temperature to below 400.degree.C.

Abstract: Alumina propping agents having a size of at least 30 mesh are introduced into a fracture created in an oil well/or gas bearing earth formation to deposit a packed multilayer distribution of said alumina propping agents.

Abstract: A composite material comprising substantially uniformly dispersed, tightly packed smooth spheres or spheroids embedded in a matrix with the size of the spheres or spheroids being between 10 and about 50 mesh USA Sieve size and the surface roughness of said spheres or spheroids being between 1 and about 70 microinches R.M.S.

Abstract: A coating system for protecting metallic substrates in reducing or oxygen-free environments which includes a first layer of chromium carbide plus metallic binder having a thickness of from 0.001 to 0.015 inches and a surface layer of all chromium carbide having a thickness of from 0.0005 to 0.005 inches.

Abstract: A wear-resistant bearing material, and process for making it, comprising hard phase particles, such as Al.sub.2 O.sub.3, substantially uniformly dispersed in a plasma deposited or detonation gun deposited soft ductile metal matrix, such as aluminum bronze, and wherein said particles are sized between about 0.05 microns and about 100 microns, and present in a volume fraction of between about 3% and 50%.

Abstract: The method for inerting the surface of a moving product involves; passing a stream of inert gas, having a width at least equal to the width of the product, into an enclosure through which the product is to pass and in the direction of the product so as to impinge upon the product surface at a predetermined angle with respect thereto and having a velocity component in a direction opposing the advancing product and a magnitude at least substantially equal to the velocity of the product.
