A self-locking electrical and mechanical connecting means and method between a helical curved end-portion of a self-supporting resilient, electrical wire-helix of a certain radius and a nominally straight-axis, metal socket-portion of an electrical terminal characterized in that the socket is plastically deformed to self-lock onto the elastically deformed and somewhat straightened wire-helix end-portion.

Self-locking electrical and mechanical connecting means and method of

A preformed radiator hose and a method of manufacturing such a hose are disclosed herein. A long length of an uncured hose is first fabricated by alternately wrapping layers of an uncured elastomer and fiber reinforcements around a straight mandrel. The uncured hose is then removed from the straight mandrel and cut into shorter segments. Each of these segments is then placed on a contoured mandrel having a shape corresponding to the intended configuration of the final hose and cured by heating. Although the fully cured hose does have a permanent shape, because of the unique arrangement of the reinforcements, etc., it has sufficient deformability to be easily slipped off the mandrel.

Reinforced formed hose

A helically fabricated electrically conductive flexible hose having a self-supporting electrically conductive helical reinforcing element of non-circular cross-section with a flat side facing inwardly and defining the outermost element of the hose bonded to a flexible plastic hose wall.

Flexible hose with external sheathed electrical conductor

In the forming of flexible tubing of at least one wire helix covered by a helically wrapped tape, an apparatus and method for making such tubing wherein an endless belt of a width a plurality of times the pitch of the wire helix is passed against a rotating mandrel surface to draw the wire helix and tape wrapping together.

Apparatus and method for forming wire reinforced helically fabricated

Flexible tubing formed of a wire helix wrapped helically with plastic tape having overlapping turns fused directly together ultrasonically, with no extraneous adhesive, and with knurling imprinted on the tubing interior, and apparatus and a method for making such tubing wherein a rotating cantilevered mandrel has a knurled anvil band over which overlapping edges of the tape pass to receive fusing vibrations from an adjacent ultrasonic horn.

Ultrasonically bonded helically fabricated tubing and apparatus and

Hose continuously manufactured with an extruded elastomeric liner with a flexible strand reinforcement laid on the outer surface thereof together with a foam/sponge insulation layer thereon which is attached to the liner between the reinforcement strands. The apparatus comprises a ram air extruder mechanism for extruding the elastomeric foam outer insulation layer, or by addition of chemical blowing agents to the insulation compound.

Method and apparatus for making insulated, reinforced flexible hose

Thermoplastic compositions comprising a resin admixture of chlorinated polyethylene with polyvinylidene fluoride are described. These compositions may be formed into a flexible film having particular utility as a laminate for web which may be employed under conditions requiring high stability and flame resistance.

Thermoplastic compositions containing polyvinylidene fluoride and

An electrical current-carrying flexible hose wherein a strip is helically wound in tubular form with interlocking tongue and groove edge portions and insulated electrical conductor means are disposed within a hollow central section between the edge portions.

Electrical current-carrying flexible hose and method of making same

An electrical conduit formed of helically fabricated grounding and reinforcing elements, including a spaced-turn foil channel defining a substantially smooth conduit bore, and an end fitting in combination with the conduit.

Electrical conduit including helical grounding and reinforcing elements

An electrical conduit formed of helically fabricated grounding and reinforcing elements, including a foil channel having overlapped turns welded to one another and to a supporting helix.

Welded-turn helical electrical conduit with electrically conductive

An electrical conduit formed of helical inner and outer channels having movably interlocked flanges, so that the channel convolutions separate on the outside of a bend of the conduit and come together on the inside of the bend.

Double-channel electrical conduit

A helically fabricated flexible hose having a self-supporting helical reinforcing element of non-circular cross-section with a flat side facing inwardly, thereby imparting a substantially smooth surface to the hose interior.

Smooth bore flexible hose

A high pressure hose construction and method of and apparatus for making the same is disclosed wherein the hose construction has a smooth walled inner liner of resilient polymeric material, and an adhesive layer, which may also be of polymeric material bonded to the liner. A braided cover is disposed over the entire layer and embedded therein. This braided cover is comprised of a plurality of elongated intermeshing strands of non-metallic fibers, such as yarn, and metallic fibers. Preferably, every three strands are of flexible, non-metallic fibers, such as nylon fibers, and every fourth strand is of metallic fiber, such as piano wire or spring steel. One set of strands crosses over and under another set to produce an intermeshing or weaving effect. These strands may also extend in a direction at an angle, such as 45.degree. or 53.degree., to the longitudinal axes of the liner, to improve the bend radius and prevent ballooning or extension or the like of the finished hose construction when used in high pressure applications.

Method for making high pressure hose
