Abstract: A tire curing membrane has a pattern of interconnected ribs integrally molded on its inside surface. The ribs collectively define a pattern of closely fitted, approximately equilateral hexagons with no non-hexagonal interstices.

Abstract: Deterioration of cord dip coating with resultant loss of adhesion of subsequently applied rubber to tire cords is avoided by using a cord dip composition including latex and an acrylic ester copolymer containing acrylic acid and methylol acrylamide.

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.

Abstract: A sole and heel construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced thin fins that extend transversely across the body. The fins are evenly spaced and uniform in width throughout. All fins are identical and are inclined relative to a horizontal plane such that any weight applied to the sole compresses the fins to trap air between adjacent fins to minimize mud build-up.

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.

Abstract: A radial ply pneumatic tire has a belt assembly which is constructed so that the laminated layers of rubberized parallel cord material in the belt are arranged in such a way that the lamina stiffnesses of the belt plies are symmetrically arranged with regard to the thickness midplane of the belt.

Abstract: A tire truing machine that has a continuously orbiting band saw moving across a tool guide that has a plurality of adjustable guide members that can be shaped to the profile of the tire to be trued or contoured to a preexisting cam profile with the cumulative guide members defining an arcuately shaped recess or guide which positions the cutting edge of a band saw adjacent to the tread of a pneumatic tire in a precise profile control. The tire is chucked and rotated as the band saw operates on the tread surface or portions thereof to the profile set or adjusted.

Abstract: A tie-back device restrains full extension of an evacuation slide until a predetermined inflation is attained. Inflation of the slide causes tension to be applied to the device. The device comprises two attachment rings and two components which are coupled by a shear pin. A transparent cover is permanently attached to one component. This cover makes the device tamperproof and nonreusable. The cover, in conjunction with the attachment rings and the two components, allows tensile forces to be applied to the shear pin from only one direction.

Abstract: An apparatus for cold branding of vulcanized tires wherein an endless conveyor is suspended from a support frame having a plurality of stations located along the closed path of the conveyor. A plurality of branding machines are mounted on the conveyor for movement therewith along the endless path of the conveyor. The conveyor means and branding machines are moved intermittently along the closed path stopping at the stations for a predetermined time interval to provide unloading and loading of tires therefrom with the cold branding being done during the movement of the tires between the stations. Heating is provided to the branding machines for heating the branding heads for branding the sidewalls of a tire carried by the branding machines.

Abstract: A combination comprising a wheel having a tire mounting rim and a pneumatic tire capable of being run in a deflated condition, the bead portions of the tire being cemented onto the bead seats of the rim with an epoxy adhesive so that the bead portions will remain on the bead seats when the tire is run without any inflation.

Abstract: A nonmetallic friction member is constructed of a bulk graphite component bonded to a resin impregnated carbon cloth component. The friction member is particularly useful for brake and clutch devices, especially multiple disc-type brakes for aircraft. The member may be in the form of a rotor or stator. If driving slots are provided, the member may be reinforced with resin impregnated carbon cloth at these slots.

Abstract: An extruder apparatus for working polymeric material having a feed screw with dual flight defining a primary channel and a secondary channel. The primary channel progressively decreases in cross-sectional area while maintaining a constant width in cooperation with the secondary channel that increases in cross-sectional area to accommodate all the melt as it changes from a solid phase to a fluent phase. The secondary flight's height is such as to accommodate the melt as it is formed in the primary channel.
