Abstract: A pipe coupling and connector for use with composite pipe, and a method of coupling the end of composite pipe are disclosed. The coupling or connector has a cylindrical inner support with a gripping surface, a means for preventing axial movement of slips that are disposed around the gripping surface, and a coupling connector. The slips form an assembly with an outer frustoconical surface and an inner gripping surface. A hollow outer sleeve with a surface that corresponds to the frustoconical surface is used to drive the slips radially inwards so that the wall of the pipe is both compressed and gripped by the coupling. A retaining member holds the outer sleeve in a fixed position relative to the slips. The coupling, connector and method of this invention provide the structural integrity needed to ensure that the end of the pipe meets or exceeds the design ratings of the pipe.

Abstract: A flexible, fiber reinforced pipe has been invented for conveying fluids. The pipe is flexible enough to be spoolable, even under winter temperature conditions. The pipe can contain pressure, when buried, unrestrained and bent. The pipe exhibits impact resistance under normal handling and can be formed using a continuous process, such that it can be manufactured as it is being laid. A flexible, fiber reinforced pipe includes an inner tubular liner having an inner surface and an outer surface; a first layer of reinforcing fibers helically wrapped about the inner liner and in direct contact therewith; an outer layer of reinforcing fibers helically wrapped about an underlying layer of reinforcing fibers and in direct contact therewith; and an outer tubular sheath applied over the outer layer in direct contact therewith.

Abstract: A cleaning device for delivering a fluid under pressure onto a surface includes a head movable on the surface for spraying the fluid and an extendable handle for controlling placement of the head. The extendable handle has a pair of sets of members arranged in telescoping relation for movement between at-rest and extended positions. One of the members is defined by a pair of sets of articulated parts with one of the articulated parts extending exteriorly of the other of the members when the member sets are in the extended position thereof. A set of resiliently urged detents releasably retain the member sets against displacement from the at-rest position thereof, and a set of pawls are operable in response to pivotal movement of the one articulated part for interlocking the other of the articulated parts and the other of the member when the member sets are in their extended positions thereof.
