Abstract: A fiber optic cable innerduct for containing and protecting fiber optic cable and for reducing the friction drag on the fiber optic cable as it is being pulled through the innerduct to allow for longer and more efficient cable pulls comprises an innerduct having a base with a circular cross section and longitudinal ribs spaced around the inner surface of the innerduct supporting the cable and for reducing friction drag on the fiber optic cable when it is being pulled through the innerduct by riding the fiber optic cable on the top ridges of the ribs.

Abstract: A safety guide for kelly spinner hoses in drilling rigs and a plurality of said safety guides in combination with kelly hoses and a rotary hose. Each safety guide comprises a pair of opposed rings, each adapted to receive and guide a kelly spinner hose, and a device for securing the rings to a rotary hose substantially in a plane perpendicular to the axis of the rotary hose. Advantageously, each ring has a rigid integral loop member and the securing device comprises a flexible band passing through said loop members. It is preferred to secure the band to the rotary hose with a buckle. In the combination, a plurality of the safety guides are spaced along the length of the rotary hose, preferably substantially equidistant.

Abstract: A flexible hose having an end connection fitting capable of withstanding high pressures and high end loads comprises a nipple having a stop ring on its outer periphery and a plurality of protruberances between the stop ring and the rear end of the nipple. A substantially tubular inner hose portion overlies the nipple, abuts the stop ring and extends away from the rear end of the nipple. A plurality of lays of spirally wound reinforcing wires overlie the inner portion of rubber and abut the stop ring. A sleeve overlies the nipple and is spaced therefrom. The inner periphery of the nipple has a roughened surface. A substantially tubular outer portion of an elastomer abuts the rear of the sleeve and overlies the reinforcing wires outside of the sleeve. A synthetic resin permeates the space between the wires and fills the space between the inner periphery of the sleeve and the inner portion of elastomer.

Abstract: A hose handling device has a fitting adapted to be secured to one end of a hose. The fitting has a peripheral groove in its exterior surface in which a ring is mounted for relative rotational movement with respect to the fitting. An eye adapted to be engaged by a hook is fixedly secured to said ring. Advantageously, the eye is formed by opposed legs which conform to the outer diameter of the ring and are secured thereto by welding or the like. Preferably, the inner diameter of the ring has a relatively flat central portion each side of which is connected to a slightly beveled portion which, in turn, may be connected to a more sharply beveled portion connected to an exterior face of the ring. To facilitate swivelling the inner diameter of the ring may have a peripheral groove communicating with a grease fitting mounted on the exterior of the ring. The fitting may be connected to one end of a hose and have its other end threaded for connection to a threaded fitting.

Abstract: A firefighting hose has an exposed woven textile jacket and an internal elastomer lining which has openings each of which is formed of a set of radiating cracks. In use, water emerging from the openings is absorbed in the jacket to protect the hose from flame and ember damage. The hose is formed by forming and uniting the jacket and lining, and making the openings by penetrating the hose with a reciprocating needle.

Abstract: A hose has an extruded tube formed of a blend of polyethylene and butyl rubber, a braided external reinforcement layer and a film applied by coating to unify and give dimensional stability to the elements of the cover. The hose is used in LP gas installations due to the non-leaching and heat-resistant characteristics of the tube material.
