US Classification:

26433114, 264104, 264105, 264507, 264663, 264 33, 264514, 264 134, 264319, 264320, 526242, 526243, 526244, 526245, 526247, 526248, 526249, 526250, 526252, 526253, 526254, 526255

Abstract:

Disclosed herein is a method to produce a semi-crystalline fluoro-polymer film. A semi-crystalline fluoro-polymer material is used. The material is compressed to produce the film. During compression, the material is maintained at a temperature below the melting point of the material. The compression step can be cycled to allow cooling of the material between compression stages. Alternative methods are provided for compressing the material with a co-extrusion substrate, extruding the material and utilizing mandrel expansion for the material.

US Classification:

72262, 72426, 226183

Abstract:

An apparatus and method for moving a wire along its own axis against a high resistance to its motion causing a substantial uniaxial compression stress in the wire without allowing it to buckle. The apparatus consists of a wire gripping and moving drive wheel and guide rollers for transporting the moving wire away from the drive wheel. Wire is pressed into a peripheral groove in a relatively large diameter, rotating drive wheel by a set of small diameter rollers arranged along part of the periphery causing the wire to be gripped by the groove.

Assignee:

Bethlehem Steel Corporation - Bethlehem PA

International Classification:

B29C 2300

B32B 2706
B32B 2732

US Classification:

428 36

Abstract:

A thick-walled, seamless, rigid conduit having a substantially uniform wall thickness which is not less than about 0. 5 percent of the outside diameter consisting essentially of an oriented crystalline thermoplastic polymer characterized by a structure comprised of radially compressed discrete, platelet-like spherulitic crystalline aggregates and having a combination of good ultimate tensile strength and low temperature tensile impact strength is described. The conduit is fabricated by solid state hydrostatic extrusion of a substantially non-oriented semi-crystalline thermoplastic polymer preform which may contain up to about 60 weight percent filler. The polymer is substantially simultaneously elongated in both circumferential and axial directions by compressive forces with the circumferential elongation being at least 100 percent. The apparatus used to produce the product is a hydrostatic extrusion press which includes an annular orifice in which the thermoplastic polymer is elongated substantially simultaneously circumferentially and axially with the circumferential elongation being at least 100 percent. Means for maintaining the rigidity of tooling and the hydrostatic extrusion fluid pressure while providing a film of the fluid on the preform for lubricity are provided in the apparatus.

Assignee:

Bethlehem Steel Corporation - Bethlehem PA

International Classification:

B30B 1130

US Classification:

425 97

Abstract:

A hydrostatic extrusion apparatus whereby semicrystalline thermopolastic polymers can be hydrostatically extruded in a solid state is described. The apparatus includes an outer tooling support means; a container assembly aligned within one end of the outer support means and having pressure means contiguous therewith whereby pressure is applied to the apparatus to both rigidly align the tooling and provide sufficient pressure for extrusion of a polymer billet within the container assembly and a receiver assembly coaxially aligned with the container assembly in the other end of the tooling means. The container assembly includes a container means, sealing means to prevent leakage of hydrostatic fluid in the container means and a die portion on the inner forward surface of the container means. The receiver assembly includes a concentrically aligned mandrel which supports and aligns a mandrel-head in spaced relationship with the die portion of the container means. Means are also provided for receiving, lubricating and cooling the extrudate in the receiver assembly.

Inventors:

Alfred R. Austen - Center Valley PA

International Classification:

F16F 126

US Classification:

267182

Abstract:

A resettable apparatus including a deformable restraining element adapted to contact and restrain active elements for producing a time-delayed force or displacement response. The apparatus functions by the release of the force and/or displacement active element by the creep deformation action of the restraining element at a time interval after actuation of the active element.

Abstract:

A hydrostatic extrusion apparatus whereby thermoplastic polymers can be hydrostatically extruded in a solid state is described. The apparatus includes: (a) an outer casing or tooling support means, (b) a container assembly concentrically contained within the outer casing and having pressure means attached thereto to provide extrusion pressure to a fluid in the assembly, sealing means to prevent leakage of the fluid, means for holding a polymer billet and including a die portion, and (c) a receiver assembly axially aligned with the container assembly concentrically within the outer casing having pressure means to clamp the container and receiver assemblies together, a mandrel for holding and aligning a mandrel-head in spaced relationship with the die, and means for receiving, lubricating and cooling the extrudate. Optionally, means for preheating and loading the polymers into the container assembly are provided whereby the press may be operated on a semi-continuous or continuous basis.
