Title: Coin telephone box with anti-stuffing coin return chute
Inventor: DEARKLAND JAMES R
IPC: H04M17/02
Filed: 1991-05-17
Abstract: ABSTRACT        Apparatus is provided in a coin operated telephone box for inhibiting the stuffing of the coin return chute of the box with foreign materials.     Coin operated telephone boxes are provided internally with a coin return chute, coin retrieval cavity below the coin discharge end of the coin return chute, and a coin return door in the front wall of the box.     The return door is pivoted at its upper edge portion for swing movement inwardly toward the coin discharge end of the return chute and provides finger access to the coin retrieval cavity for the removal of coins from the box.    To inhibit stuffing of the coin return chute there is provided a first gate plate, affixed to and carried by the return door proximate its lower edge portion, which partially spans the open top portion of the coin retrieval cavity.      A second gate plate is pivotally attached to the coin return chute at its coin discharge end and such second gate plate extends downwardly to the upper surface of the first gate plate proximate the rearward edge portion thereof.    The first and second gate plates cooperate to close off access to the coin return chute from the coin retrieval cavity when the coin return door is closed or pivoted inwardly.          The second gate plate is pivotally movable away from the first gate plate by coins descending within the coin return chute to the first gate plate for sliding discharge along the first plate into the coin retrieval cavity.

Abstract: METHOD FOR GRAFTING PREFORMED HYDROPHILIC POLYMERS ONTO         HYDROPHOBIC POLYMER SUBSTRATES                           ABSTRACT     Coatings of hydrophilic organic polymers such as polyvinyl alcohol are grafted to substrates formed from hydrophobic organic polymers and polyorganosiloxanes by exposing the surface of the substrate to an aqueous solution of the hydrophilic polymer in the presence of a solubilized compound of tetravalent cerium that preferably contains hydroxyl or amino groups as ligands.  The conditions of the exposure are sufficient to graft at least a portion of the hydrophilic polymer to the surface of the substrate.
