摘要:
A method of making a lightweight hose assembly including a step of extruding the inner liner. A nonmetallic material is then braided about the exterior of the liner. The inner liner and braided layer are then passed through a reservoir containing a solution of the fluorocarbon polymer. The solvent is then removed, leaving a fluorocarbon polymer coating dispersed throughout the braided layer.

An applicator for applying resin to fibers being braided in a tubular shape (e.g., in the manufacture of a fuse casing), the applicator having a wiping surface on which the fibers wipe as they travel to a mandrel on which they are braided, the wiping surface being defined by a surface of revolution around the mandrel and having a continuous orifice for supplying resin continuously around the wiping surface. Also disclosed is an electrical fuse including a fuse casing having a tubular wall including multiple-filament reinforcing yarns that have been braided in the tubular shape of the wall and a synthetic resin bonding the yarns together and impregnating the yarns, a pair of terminals secured to the ends of the fuse casing, and a fusible element inside the casing and connected to the terminals.

A lightweight hose assembly of the type adapted for carrying fuels and other corrosive fluids. The assembly (10) includes a tubular member (11) and a pair of coupling members (20). The tubular member (11) includes an inner liner (12) of a fluorocarbon polymer. A glass fiber is braided about the exterior of the inner liner (12) to form a braided layer (13). The assembly (10) further includes an outer fluorocarbon coating (14) dispersed throughout the braided layer (13) for preventing kinking or permanent deformation of the inner liner (12). A conductive strip (16) is formed on the inner liner (12) for dissipating electrical charges accumulated in the inner liner (12). A method of making the assembly (10) comprises the steps of extruding the inner liner (12). A nonmetallic material (13) is then braided about the exterior of the liner (12). The inner liner (12) and braided layer (13) are then passed through a reservoir containing a solution of the fluorocarbon polymer. The solvent is then removed, leaving a fluorocarbon polymer coating (14) dispersed throughout the braided layer (13).

An electrode supporting conduit tube for electrical heating of underground hydrocarbon resources comprises a metal conduit tube and an insulating member adhered on and around the outer peripheral surface of the metal conduit tube. The insulating member is a laminated body of a web of glass fiber impregnated with water-dispersion varnish of a hot-water resistant and thermoplastic resin and a polyether/ether/ketone resin film, which is formed by first alternately winding the glass fiber web and the resin film on and around the outer peripheral surface of the metal conduit tube for a plurality of winding turns, and then subjecting both polyether/ether/ketone resin film and glass fiber web thus wound on and around the metal conduit tube to shaping under heat and pressure at a heating temperature of from 350.degree. C. to 450.degree. C, and under a pressure of from 10 kg/cm.sup.2 to 200 kg/cm.sup.2.

There is disclosed an improved apparatus for making flexible hoses comprising a means for storing and unwinding reinforcing threads needed for hose building, said means comprising a set of joinable drum storing platforms as a thread applying means capable of simultaneously applying reinforcing threads in the order of magnitude of a thousand to the flexible hose to be manufactured; at least one driving mechanism being capable of positively gripping any part of the hose and being capable of advancing or advancing and rotating the hose; optional input means for supplying heat, e.g. electric current, to said hose for vulcanization or other heat treatment; supplementary support means for allowing and promoting the advancing or the advancing and rotating movement of the hose, said support means being arranged along a track of hose movement of any desired shape; and elements of adjustable height located within a track section of the driving mechanism wherein the height of said elements is preferably set and controlled automatically by the hose itself while it is being built up from its component parts.
摘要:
A machine for producing pile fabric comprises a sonotrode (1) , a matrix (4) of tubes (5) bringing threads (10) onto a support sheet (7) for the purpose of welding rows of loops to the surface of this sheet. The matrix (4) is guided between slides (6) which are parallel to the longitudinal axes of the tubes (5) and perpendicularly to the surface of application of the sonotrode (1) vibrations. A driving mechanism (13, 14, 15) periodically brings the extremities of the tubes (5) from which the threads leave against the sonotrode (1) by pressing the base of a row of loops and the support sheet (7) against the sonotrode in order to cause them to be welded together.
摘要:
A method of manufacturing a pressure tank comprises forming the tank with an inner thin wall of light metal and applying a backup wrapping of resin impregnated fibers having a large breaking strength and a small coefficient of thermal expansion to the tank and the tank is cooled in order to compensate for the accumulating filament tension during the winding operation.
摘要:
A process and apparatus are disclosed for the simultaneous preparation of several hollow fiber devices especially useful for fluid fractionation operations, wherein at least one hollow fiber is wound around means, at least three in number, located in different planes thereby obtaining with this fiber an envelope having a polygonal section, which can be cut in at least two places as it is formed, so as to obtain at least two distinct groups of hollow fiber lengths. Various specific embodiments are described.
