    Abstract: A pneumatic tire transporter is provided for dismounting and transporting a pneumatic tire, tire carcass or the like from a collapsible tire building drum. The transporter includes a transport cage frame capable of being positioned circumferentially about a portion of a pneumatic tire assembled on a collapsible tire building drum. A plurality of support pads are spaced about and slidably supported on said cage frame preferably in two spaced circumferential sets. The support pads are capable of moving radially inwardly to engage the pneumatic tire assembled on the building drum at least adjacent opposite axial end portions of the building drum. The cage frame is supported and moved by a transport base member that is capable of moving the cage frame horizontally to dismount said pneumatic tire from the collapsible building drum and preferably thereafter rotating said pneumatic tire to a vertical position for detaching the detachable means and the pneumatic tire from the remainder of the transporter.

    Abstract: A novel class of resins having excellent impact strength, flexural modulus and heat distortion characteristics consists essentially of blends of vinyl aromatic polymers and graded ABA block copolymers in which each A represents essentially polymerized styrene, the other monomer incorporated in the block being butadiene, and B represents essentially polymerized butadiene, the other monomer incorporated in the block being styrene. In each ABA block copolymer the weight ratio of total A to total B ranges from about 50:50 to 35:65. The block copolymers are preferably present in an amount sufficient to give a total styrene content, both as homopolymer and copolymer, of about 75 to 94, preferably 80 to 85, weight percent based on the total blend. In the blends of this invention, the discontinuous phase, made up of the graded block copolymers, is present in the form of particles of which at least 70%, preferably 85% or more, by weight have particle diameters in the range of 0.2 to 5 microns as measured by the ''''Zeiss Particle Size Analyzer''''.

    Abstract: This invention comprises blends of otherwise relatively imcompatible polymers, particularly vinyl aromatic polymers and conjugated aliphatic diene polymers, by the incorporation of graded ABA block copolymers, the A and B segments of which are compatible with the otherwise relatively incompatible polymers in the blend. Of particular importance is the embodiment comprising blends of styrene and butadiene polymers in molar ratios of from about 2:1 to about 5:1 with certain graded ABA styrene-butadiene block copolymers acting as surfactants thereby producing a novel class of resins having excellent impact strength, flexural modulus and heat distortion characteristics. The block copolymers have a weight ratio of A:B in the range of 45:55 to 60:40 and are present in an amount sufficient to give a total styrene content, both as homopolymer and copolymer, of about 75 to 95 weight percent based on the total resin in the blend. In the blends of this invention the discontinuous phase, made up of the diene polymers and the block copolymers, is present in the form of particles of which at least 70, preferably 85 or more, weight percent have particle diameter in the range of 0.2 to 5 microns as measured by the ''''Zeiss Particle Size Analyzer''''.

    Abstract: A pneumatic tire carcass building machine has a cylindrical building drum adapted for forming thereon a tire carcass of rubberized cord plies. Bead portions of the tire carcass are made by forming bead ring receiving shoulders in a rubberized fabric ply or plies positioned on said drum at each side of said drum with shoulder forming means, abutting or seating annular bead rings with said bead ring receiving shoulders with bead ring seating or carrier means positioning and holding the bead rings concentrically with bead lock means, and wrapping edge portions of the ply around the bead rings with turnover means while maintaining the concentric position of the bead rings with the bead lock means. Preferably each bead lock means includes at least three bead clamps spaced radially about the shaft of the cylindrical drum in preferably symmetric array, which clamps are driven from preset retracted positions to preset extended positions where they concentrically position the bead rings during turnover of edge portions of the carcass ply or plies.

    Abstract: Rubber compounds are readily bonded to polyester reinforcing elements, particularly tire cords of polyester fibers, using a one-step dip process in which the dip consists essentially of an alkaline aqueous emulsion of a minor amount by weight of a mixture of a major amount by weight of a rubbery vinyl pyridine copolymer and a minor amount by weight of a heat reactable 2,6bis(2,4-dihydroxy phenylmethyl)-4-chlorophenol composition, wherein said emulsion is essentially free of alkali metal materials and wherein the emulsifier used in the emulsion is an ammonium salt or soap. High aged H-adhesions are obtained with this process.

    Abstract: A method and apparatus for assembling articles, especially bushings, of the type having a generally cylindrical or oval elastomeric insert, a rigid outer sleeve, and a rigid inner core. The sleeve and the core are positioned within the fixture of the present invention and the bottom portion of the insert is located within the top portion of the outer sleeve. The positioning of the parts is such that the outer sleeve, the insert, the inner core, and the apparatus define an included chamber which is substantially air-tight. A vacuum is then applied to the enclosed chamber and the resulting suction on the bottom portion of the insert, together with any additional external force that may be required, cause the insert to move into assembled position, radially compressed, between the inner core and the outer sleeve.
