Abstract: A segmental annular safety support having swivel hinged segments for mounting on a rim inside a tire chamber with at least one of said segments having resilient means at the inner periphery for compression between the rim and segment when the segments are latched together to provide preloaded clamping of the support on the rim.

Abstract: Tubular tire for motor vehicles, of the type including an inflatable tubular inner (pneumatic) tube, a bracing, a case of the radial type, a rim strip, some rubber sides, a tire tread and two semi-rigid circular rods. The two rods 7 are set at the level of the bracing 2 at the edges thereof; the rim strip 4 has a width included between approximately 0.25 L and approximately 0.35 L; the transverse section of the tire has an H/L ratio included between approximately 0.5 and approximately 0.6; the sides 5 of the tire have a profile corresponding to that of the top part of the curve which represents the equation of a classic radial tire; the aggregate is such that, seen in transverse section, the tire fairly forms an isostable triangulated system.

Abstract: A heat sensitive, but stable, gellant system is added to a foam latex during manufacture of the latex or as an additive ingredient being incorporated at the time of preparing the liquid foam compound. The system is comprised of an amphoteric surfactant acid or an amphoteric surfactant acid neutralized with a fixed alkali, said surfactant being capable of both sensitizing the latex emulsifier and functioning as a stabilizer; a water soluble ionizable organic or inorganic acid capable of activating the gelation mechanism and a water soluble, volatile, organic or inorganic base which is added in an amount sufficient to neutralize the combination of the surfactant and the acid to a pH of 8 to 12.

Abstract: Brass coated steel tire cord is treated with vaporized benzotriazole and/or other treatment agents to promote corrosion resistance and cord to rubber adhesion retention.

Abstract: A segmental annular tire safety support for mounting on a wheel rim to support a pneumatic tire in the deflated condition. The safety support includes a segmental curved member having a generally cylindrical radially outer supporting surface of revolution with a substantially constant radius circumferentially of the tire safety support. The ends of the curved member have radially outer end surfaces which are relatively flat and are spaced from the axis of the support a distance less than the length of the radius of the outer supporting surface of the curved member to reduce the stresses generated at the end edges and to provide warning vibrations and noise during operation of the tire in the deflated condition.

Abstract: An improved process of preparing phenolic antioxidants in increased yields with superior color properties, the improvements being obtained by carefully controlling process variables such as the temperature of the reaction, moisture level and catalyst level.

Abstract: Amide and imide age resistors such as N-(3,5-di tert.butyl-4-hydroxyphenyl) acrylamide and N-(3,5-di tert.butyl-4-hydroxyphenyl) itaconimide, age resistant polymers having amide and imide age resistors physically combined therewith and age resistant polymeric compositions prepared by free radical polymerization techniques involving the use of said amides and imides as monomers.

Abstract: Ester age resisters such as 4-anilinophenyl acrylate and 4-anilinophenyl methacrylate, age resistant polymers having ester age resisters physically combined therewith and age resistant polymeric compositions prepared by free radical polymerization techniques involving the use of said esters as monomers.

Abstract: A support member curved about an axis of revolution for mounting on a wheel rim inside a tire chamber to support the tire in a deflated condition. The support member has a generally U-shaped cross section and may have open ends or the ends may be closed with webs having edges joining the radially inner and outer peripheral edges of the support member.A relatively lightweight high-strength material such as reinforced plastic may be used in the construction of the support member with relatively long fibers of reinforcing material extending generally in planes containing the axis of revolution and relatively short fibers of reinforcing material extending generally circumferentially of the support member and in planes perpendicular to the axis of revolution. Heat-conducting material in the form of wire screen or short lengths of wire may be embedded in the support member to conduct heat away from the surface engaged by a deflated tire.

Abstract: An enclosed container having a divided chamber with an air pressure section and a liquid coolant section separated by a pressure-transmitting wall. A one-way inflation valve in the container is in communication with the air pressure section for inflation of this section. A liquid release valve in the container is in communication with the liquid coolant section and is set to release liquid into a tire cavity when the tire is operated in a deflated condition. The container is of a resilient, noncollapsible material for retaining air under pressure and for gripping the rim on which the tire is mounted.

Abstract: Ester such as 3,6,9-trioxyundecane-1,11-bis (3-n-dodecylthiopropionate) when combined with conventional free amine antioxidants such as N,N'-diphenylparaphenylenediamine or with polymer bound antioxidants such as N-(4-anilinophenyl) methacrylamide produce improved antioxidant systems for SBR and NBR type polymers.
