US Patent:

39469182, Mar 30, 1976

Filed:

Jun 23, 1975

Appl. No.:

5/589712

Inventors:

William R. Babbin - Barberton OH
Stephen C. Sabo - Barberton OH

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

B65H 1724

US Classification:

226 1

Abstract:

Limp, elastomeric hose is fed through a pressurized chamber having an inlet and an outlet opening, the outlet opening leading directly to a pressurized hose treatment zone. Seals at both the inlet and outlet opening of the chamber simultaneously permit continuous passage of hose and prevent escape of the pressurizing fluid from the chamber and from the treatment zone. The hose is driven from the inlet end of the chamber up to and out of the outlet seal of the chamber, and into the treatment zone by a pair of vertically spaced substantially mutually parallel, endless, flexible belts disposed within the chamber.

International Classification:

B60C 906
B60C 1700
B60C 1502

US Classification:

152354R

Abstract:

A pneumatic tire which can be operated in a deflated condition without damage to the tire, wherein the tire has a cord ply, a tread, a ply with wire cords in the crown, and thick sidewalls wherein the cord ply extends from the heel of the bead to a location closely adjacent to the outer surface of the midpoint of the sidewall and then towards the inner surface of the crown. The interior portion of the sidewall rubber has a high dynamic modulus with low hysteresis properties and high aging properties.

International Classification:

B29H 1720
B29H 1726
B60C 920

US Classification:

156117

Abstract:

A radial pneumatic tire and a method of making same. The tire has a discontinuous cord belt reinforcement comprising narrow strips of fabric wound around the tire in a plurality of circumferential overlapping turns. The tire is capable of being built in one stage and shaped into toroidal shape after the circumferential belt is applied.

International Classification:

B60C 512

US Classification:

152357A

Abstract:

A vehicular pneumatic tire which, except for bead cores, is composed solely of an elastomeric blend strengthened by molecular orientation. The blend is a monoolefin copolymer rubber with a polyolefin and sufficient curing agents to effect vulcanization when the blend is subjected to heat and pressure. The process for making the tire comprises preforming an annulus of the elastomeric blend with bead cores adjacent the edges, the diameter of the preform being essentially that of the bead diameter of the completed tire and the axial distance between the beads less than the transverse arcuate dimension of the completed tire. The preform is cured and while still hot following curing, is stretched and shaped to final size and the generally toroidal form characteristic of conventional pneumatic tires with resulting biaxial molecular orientation, which orientation is retained in the tire by cooling it below the melting point of the polyolefin before removing the tire from the mold.

Appl. No.:

5/584056

Inventors:

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

B29D 2300
B29H 714

US Classification:

425445

Abstract:

An apparatus adapted for continuously vulcanizing elastomeric hose comprises a tubular, helically extending vulcanizing chamber with an entrance for unvulcanized hose at one end and an exit for vulcanized hose at the other end. Means are provided to circulate fluid at elevated temperatures and pressures through the chamber thereby transporting the hose therethrough while simultaneously providing the heat and pressure required for satisfactory vulcanization. Special sealing means are provided to permit the flaccid hose structure continuous entry to the chamber while effectively preventing escape of pressurized fluid contained therein.
