摘要： The invention relates to rigid, open-celled hydrophilic polyurethane foams obtained by reacting in the presence of water as a blowing agent and a polyisocyanate with a polyhydric polyamine initiated polyether polyol. The polyether polyol is initiated with a polyhydric polyamine having three (3) to five (5) active amine hydrogens and has internal blocks of polyoxyethylene groups. The foam retains from 15 to 35 times its weight in water.

摘要： The invention relates to rigid integral skin polyurethane structural foam having high impact strength, high heat distortion, and flame retardant properties. The foam is prepared from triisopropanolamine-initiated polyoxyalkylene (TIPA) polyether polyols oxyalkylated with a compound producing primary hydroxyl functional termination. The polyether polyol is advantageously of a molecular weight sufficient to enable TIPA to flow well while retaining its flame retardant characteristics in the foam.

摘要： The present invention relates to low density, water-blown, rigid foams with good physical properties made with blends of toluenediamine (TDA)/glycerine initiated polyols. The foams made using these blends exhibit no initial surface friability. Further, it was found that specific blends of lower hydroxyl number polyols could be used, thereby reducing isocyanate consumption without affecting the physical properties of the foam.

摘要： A multi-channel communications system for communications between a mobile units and dispatch agencies through tower sites under control of a multi-channel communication controller. The method of communications used is time division multiple access with provisions for alternate methods. The mobile units and dispatch agencies have forms of identifications to route messages between the mobile units and dispatch agencies according to the forms of identification. The forms of identification are resolved from one form to another to operate with the alternate methods of communications. The mobile units are handed off from one communications channel to another by the multi-channel controller as channel loading conditions exceed a predetermined limit. Mobile units change tower sites as the geographic coverage of a tower site changes. Mobile units determine distance to a tower site by computing distance to a tower site by using GPS position information of the mobile unit and the known locations of the tower sites to compute signal strength.
