Abstract: A pneumatic tire inflation device and method is disclosed, the device comprising an arrangement of parts that enables its user to selectively gradually inflate a tire at a specified intermediate rate and pressure, and then to selectively suddenly continue such inflation at a substantially greater rate and pressure until complete inflation is achieved.

Abstract: An inner tube assembly for a pneumatic tire, comprising a primary annular tube, a secondary annular tube surrounding the primary annular tube, an annular primary tube-restraining band interpositioned between the primary and secondary tubes, and valves intercommuncating the primary and secondary tubes with one another, is disclosed. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way.

Abstract: A raw pneumatic tire carcass having an uncured, elastomeric, annular body and an uncured, elastomeric, liner superposed upon and affixed to the internal surface of the body, is disclosed. The liner in one form thereof includes bead-communicating recesses for venting fluid from between the liner and an inflatable bladder used in a mold for effecting inflation of the body and liner from a cylinder to a torus. The liner in the latter form is constituted of an appropriate thermoplastic material which, when engaged and inflated by a smooth surface of the bladder and vulcanized, undergoes a transformation in which the recesses gradually disappear substantially and are transformed into a correspondingly smooth surface. A second form of the liner (which is preferably incorporated as part of the first said form of the liner) is represented by a convexity on at least one surface of the liner.

Abstract: A broad class of furan-3-carboxamide derivatives has been found to possess good fungicidal, insecticidal and nematocidal properties.

Abstract: A high speed pneumatic tire with a tread whose width of running contact with the ground is automatically variable. The tread consists of a central portion that is in constant contact over its entire width with the ground and two lateral shoulder portions which are respectively arranged on each side of the central portion and are each separated from the central portion by an essentially continuous circumferential groove that forms a flexible joint or coupling. Each lateral shoulder portion of the tread is radially contracted and inclined with respect to the central portion so that it contacts the ground where required by the dynamic forces on the tire, e.g., acceleration, turning and braking. The central and lateral shoulder portions of the tread each may have the same or different design patterns for particular purpose, e.g., snow, anti-skid.
