Apparatus and method for terminating flexible pipe body

A method and apparatus are disclosed for terminating flexible pipe body. The apparatus comprises an end fitting core portion (330), an end fitting termination portion (310) and a spacer ring member (335) locatable between the core portion (330) and the termination portion (310) for maintaining a whole anterior end surface of the core portion (330) and an opposed whole posterior end surface of the termination portion (310) in a spaced apart relationship.

Tread with concealed cavities comprising a wear indicator having improved visibility

A tire comprising a tread, this tread comprising at least one channel and at least one wear indicator that is disposed on the bottom of the channel. The wear indicator has a contact face which is intended to come into contact with a road surface when the tire reaches a wear limit. The contact face has a texture that contrasts with the bottom of the channel.

Woven Irrigation Tubing, Apparatus and Method of Making Same
20220080685 · 2022-03-17 · ·

Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

System for a Self-Recoiling Hose
20220082193 · 2022-03-17 ·

A system for a self-recoiling hose provides an expandible-length hose that automatically condenses to a smaller size upon completion of usage. The sheath includes a set of elastic fibers that is interwoven with a set of rigid fibers, thus allowing the expandable hose to elongate to a maximum length that is within a reasonable predetermined length range. This prevents the inner tube from expanding beyond its intended length. The apparatus further provides a connection mechanism for expandable hoses. The apparatus is designed to prevent any possible leakage between one or more expandable hoses and the apparatus. A threaded connector enables chain attachment of the expandable hose to other hoses. Another unit fits inside the inner channel of an expandable hose, while a third part surrounds the inner channel of the expandable hose. An annular fastener secures the outer channel of the expandable hose to the inner channel.

Material for use in lining pipes
11268645 · 2022-03-08 · ·

A material for use in lining pipes is disclosed. A warp-knitted tubular fabric (24, 64) in which the stitch used (for example a tricot stitch) is of a type that reconfigures as the tube is expanded radially to contract longitudinally is sufficiently flexible and compressible to enable it to conform to pipe structures. The fabric of this invention is infused with resin, which is cured once the liner is in place within the pipe. Potentially, this fabric may be thinner than known prior art materials, but exhibits comparable strength and conformability, which are necessary characteristics in the repair or rehabilitation of pipes. The use of a thinner fabric material reduces constriction of the pipe bore by repair and also offers the potential for cheaper lining material, as less resin is required. The fabric may be knitted from glass fibre yarn, which is non-toxic and a stronger material than generally used in the prior art.
