Abstract: A hammock is supported by vertical supports connected to hammock spreader bars at the head end and the foot end of the hammock at two vertically displaced points. An intermediate support comprising a transverse flexible strap suspended between the vertical support members at a user's knee region of the hammock raises the hammock in the knee region so as to remove the concavity at the location and reduce backward knee joint stress on the person reclining in the hammock.

Abstract: Scale inhibitor is added to a cross-linked fracturing fluid as an integral part of the fracturing fluid. Preferred fracturing fluids are borate cross-linked and the preferred scale inhibitor is polyacrylate. In another embodiment of this invention, the fracturing fluid is prepared by adding a scale inhibitor to a fracturing fluid at a pH of between 8.5 and 10.5. In a third embodiment, the fracturing fluid prepared above is used to fracture subterranean formations. In a fourth embodiment, the fracturing fluid is used to pressurize a subterranean formation to break scale near the hydrocarbon wellbore.

Abstract: An aqueous composition comprises an aminopolycarboxylic acid and a water-soluble organosilicon compound. The composition is useful for removing scale from well equipment and/or openings in a subterreanean formation, and for stabilizing fine particles within the formation to prevent their subsequent movement. Fluid flow through formations and wells treated with the composition tends to be increased and more stable.

Abstract: Subterranean formations are treated with acid, by a method comprising the steps of: (1) forming an acidizing composition by mixing an aqueous acid component with at least one water-soluble organosilicon compound; and (2) injecting the composition into the formation. Suitable organosilicon compounds include water-soluble organosilanes and organosilanes which hydrolyze to form water-soluble silanols. By using the organosilicon compound, movement of formation fine particles is inhibited and swelling of clays by aqueous fluids is reduced, thus tending to maintain formation permeability.

Abstract: A portable cylindrical dispenser having a side casing member with a cutout therein for permitting access to the articles inside the dispenser. The articles are a plurality of like articles, especially coiled nails, which are stacked one on top of the other. The dispenser includes an open top receptacle comprising a generally tubular side casing member and a bottom end closure member inwardly joined thereto, and a top end closure member removably secured to the receptacle for closing the open top. The dispenser may be either a top discharge dispenser, in which case the cutout is long and narrow, extending downwardly from the top but terminating short of the bottom, or a bottom discharge dispenser, in which case the cutout is situated adjacent to the bottom closure member and is wide enough and high enough to permit removal of an article from the dispenser. The cutout may be either a removable part of the side casing member, e.g.

Abstract: A method for treating a subterranean formation, or a well penetrating the formation, comprises injecting into the well an aqueous composition containing an aminopolycarboxylic acid and a water-soluble organosilicon compound. By use of the method, scale is removed from well equipment and/or openings in the formation, and fine particles within the formation are stabilized to prevent their subsequent movement, resulting in increased, more stable fluid flow through the formation and well.

Abstract: A radial tire, specially for a motorcycle, comprising a carcass reinforced by a ply radially disposed cords wrapped in each of two bead regions around an annular bead core to provide a ply turn up, a tread reinforced by a breaker assembly and between the tread edges and bead region tire sidewalls wherein each sidewall includes immediately adjacent to and outwards of the carcass ply a rubber sidewall member modulus in the range 10-20 MPa and having a upper edge positioned at the edge of the breaker and a lower edge radially inwards of the carcass ply turn up edge.

Abstract: A composition for use in enhanced oil recovery procedures comprises steam having a vapor phase and a liquid phase and a fluorocarbon surfactant partitioned between the liquid and vapor phases. The partitioning of the fluorocarbon surfactant between the two phases is accomplished by maintaining the composition's pH at less than about 11, and preferably within the range of 7 to about 11. By varying the fluorocarbon surfactant concentration, the composition can be used as a surface tension depressant well stimulation additive and/or as a foam former for selectively blocking more permeable portions of a formation.

Abstract: A self-breaking, foamed, oil-in-water emulsion contains a water-immiscible organic solvent for paraffins and asphaltenes, an aqueous nonformation-damaging component, an inert gas, and surface active agents selected to promote a stable foamed emulsion despite contact of the treating fluid with the hydrocarbon and aqueous environment in the reservoir. Under conditions of agitation, the treating fluid is a stable foamed emulsion which undergoes spontaneous breakdown into two liquid phases under quiescent conditions. The treating fluid is injected and/or circulated as a stable foamed emulsion to dissolve paraffin and asphaltene-containing deposits from various substrata, such as a subterranean reservoir penetrated by a well, the well itself, or an industrial vessel or conduit. When injection or circulation is stopped, the foamed emulsion spontaneously breaks down so that the treating fluid can be readily pumped from the well.

Abstract: Subterranean formations at temperatures above 250.degree. F. are acidized by introducing a solution of a halogenated hydrocarbon and an organic solvent and allowing the halogenated hydrocarbon to hydrolyze in an aqueous medium to form a hydrohalic acid. Corrosion of metals, e.g., well casing, is inhibited by the presence of the solvent. The acidizing solution can be introduced as a liquid or as a mist in a substantially anhydrous gas. The aqueous medium can be naturally present in the formation or can be introduced into the formation as a liquid or as a foam simultaneously with the acidizing solution.

Abstract: Foamed treating fluids contain an acid component, a gas, optionally an organic solvent and emulsifying agent, and, as a foaming agent, a mixture of a quaternary ammonium halide cationic surface active agent and either an alkylamido alkylamine oxide surface active agent or a betaine amphoteric surface active agent. Such treating fluids can be used to dissolve acid-soluble components from various surfaces, such as a subterranean reservoir penetrated by a well, the well itself, or an industrial vessel or conduit containing a scale.
