Method of and apparatus for introducing pulverulent material into a tire
First Claim
1. A method of introducing a pulverulent material into a tire through a tire valve stem comprising the steps of(a) confining a predetermined amount of pulverulent material,(b) subjecting the confined pulverulent material to pressurized cyclonic air currents moving along a generally horizontal flow path,(c) progressively altering the generally horizontal flow path to an inclined flow path, and(d) introducing the pulverulent material into a tire through an associated tire valve stem under the influence of the pressurized cyclonic air currents.

Abstract
A method of and apparatus for introducing pulverulent material into a tire through a tire valve stem is performed by confining a predetermined amount of pulverulent material in a cylindrical chamber having axially spaced and radially offset inlets and outlets, subjecting the confined pulverulent material to pressurized air which is transformed into a cyclonic air current within the chamber by the radially offset inlet and outlet, and introducing admixed air/pulverulent material from the chamber into a tire through its associated tire valve stem.

3. A method of introducing a pulverulent material into a tire through a tire valve stem comprising the steps of
(a) confining a predetermined amount of pulverulent material in an essentially rigid chamber having a single air inlet and an air outlet which are radially and axially offset, (b) subjecting the confined pulverulent material to pressurized cyclonic air currents moving along a generally inclined flow path descending in the direction of flow, and (c) introducing the pulverulent material into a tire through an associated tire valve stem under the influence of the pressurized cyclonic air currents, the amount of pulverulent material so introduced being sufficient to effect dynamic balancing of said tire and an associated wheel assembly.

4. A method of introducing a pulverulent solid material into a tire through a tire valve stem comprising the steps of:
-
(a) confining a predetermined amount of pulverulent material in an essentially rigid chamber having a single air inlet and an air outlet which are radially and axially offset and at opposite ends of said chamber, (b) passing a pressurized air stream successively through said air inlet passageway, said chamber and said air outlet passageway, the pressurized air creating cyclonic air currents within the chamber and thereby creating an essentially uniform admixture of said pulverulent material and air, and (c) introducing the resulting admixture of said pulverulent material and air into a tire through an associated tire valve stem under the influence of the pressurized cyclonic air currents, the amount of pulverulent material so introduced into the tire being sufficient to effect dynamic balancing of said tire and a wheel assembly associated therewith but insufficient to substantially fill said tire. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An apparatus for introducing a pulverulent material into a tire through a tire valve stem comprising:
-
(a) an essentially rigid and essentially cylindrical chamber for confining a predetermined amount of pulverulent material, said cylindrical chamber having a single air inlet and a single air outlet which are radially and axially offset and at opposite first and second ends of said chamber, said air inlet and said air outlet being axially remote and non-aligned whereby the confined pulverulent material is subjected to pressurized cyclonic air currents when pressurized air is introduced through said air inlet, (b) a source of pressurized air, (c) a flow path for pressurized air extending from said source of pressurized air to said air inlet, said flow path having a pressure regulator therein, and (d) means for introducing an admixture of pressurized air and said pulverulent material into a tire through an associated tire valve stem under the influence of the pressurized cyclonic air currents, the volume of said chamber being sufficient to contain an amount of pulverulent material sufficient to effect dynamic balancing of said tire and an associated wheel assembly but insufficient to fill said tire. - View Dependent Claims (18, 19, 20, 21, 22, 23)
