  • Patent number: 5695577
    Abstract: A method for the production of patch-rubbers intended to repair radial-ply and bias-ply tires. The patch-rubbers, although having the same strength as those known, are more flexible and do not affect the original mechanical features and performances of the regions of the tires repaired therewith, and are also suitable to perform retreading operations on tires by both high pressure molding machines and autoclaves. The method consists in superposing the plies (1a, 1b), embedding a fabric made by fiber cords, in such a way that their medium axes diverge from the longitudinal or symmetry axes A of the patch-rubbers, and in superposing on the plies, a further ply (2) of smaller area having rectilinear metallic cords forming a different angle with the above mentioned axes A.

  • Patent number: 5609715
    Abstract: A repair apparatus for tire punctures is operable upon a damaged tubeless tire in situ and includes a hollow probe initially containing a rubber boot disposed in a collapsed condition but subsequently automatically unfolding when urged into the tire interior by a plunger rod in the probe. A stem integral with a circular main body of the rubber boot is connected to the plunger rod by a flexible tether that serves to retain the unfolded boot juxtaposed the puncture point inside the tire while a drive rod forces a measured amount of rubber bonding fluid through the probe to sealingly secure the boot. Alignment and retention of the probe and drive rod is facilitated by a mounting unit secured to the tire by adjustable attachment elements clampingly engaging the rim of the wheel mounting the tire while threads on the probe and drive rod cooperate with tapped bores in the mounting unit to permit controlled advancement and retraction of the probe and drive rod.

    Abstract: An improved golf ball comprising a hollow, spherical shell of a polymeric material; a unitary, noncellular core of a material which, at the time of introduction into the shell, is a liquid and a one-piece spherical cover over the center. The spherical shell, as opposed to the core, is primarily responsible for the high initial velocity obtained when the golf ball is struck by a golf club so as to allow the golf ball to be driven long distances both in the air and on the ground when it lands. In an alternate embodiment, the center and cover are of a one-piece, blow-molded construction.

  • Patent number: 5403417
    Abstract: A punctured, substantially deflated pneumatic automotive tire is internally sealed using a specially designed sealant canister containing CO.sub.2 gas propellant and a tire sealant mixture. The canister sealant comprises approximately 97% by weight of an acrylic latex material which is present with the propellant under a pre-use internal pressure of about 55-65 psig. An outlet cone portion of the canister is removably connectable to the tire inflation valve, and the internal volume and pre-use pressure of the canister are related to the internal volume and normal full inflation pressure of the tire in a manner such that the canister is operative to deliver essentially its entire contents into the tire, yet only partially inflates the substantially deflated tire past its initial pressure.

  • Patent number: 5350481
    Abstract: Disclosed is a device to repair ruptures in the wall of a flexible pressurizable enclosure. The device has an apertured plate on the wall's outer surface, and has a threaded fastener protruding through the aperture and rupture into the enclosure. A butterfly member threaded to the fastener within the enclosure has clamping members swingable out from the fastener so that engagement surfaces on the clamping members face the ruptured zone of the wall. A layer on the engagement surfaces has a curable adhesive resin initially segregated from a setting agent therefor, which is also in the layer. The segregation of resin and setting agent is achieved by enclosing at least one of these substances in capsules distributed within the layer. Once the clamping members swing away from the fastener, turning the fastener moves the clamping members to press them on the inner surface zone of the enclosure wall. The wall is thus sealingly pressed between the clamping members and the plate on the wall's outer surface.

  • Patent number: 5160394
    Abstract: The invention comprises a method and apparatus for repairing a ruptured sidewall in a truck tire which eliminates bulging. The method includes the inventive step of removing the sidewall reinforcement pad from the interior of the repair area after curing the tire. The apparatus used to perform this operation comprises a sidewall reinforcement pad having a metal layer disposed between two layers of rubber. In one preferred embodiment, the metal layer is comprised of longitudinally disposed metal cords. The metal cords give additional strength to the section repair patch and prevent bulging of the ruptured repair area during the curing process.

  • Patent number: 5150906
    Abstract: An improved golf ball having a coefficient of restitution of at least 0.700 and comprising a hollow, spherical shell of a deformable polymeric material which is filled with either a liquid or a unitary, non-cellular core of a material which, at the time of introduction into the shell, is a liquid. The spherical shell may be solid or cellular. The core material may be added through a hole in the shell as a liquid, a gel or a melt. In the preferred embodiment, the spherical shell is formed from two half shells which are bonded to each other. The mating edges of the half shells may have surface configurations which maximize their contact area.
