Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
A DEVICE FOR INJECTING CATALYZED RESIN INTO A RECEPTACLE WHEREIN THE RESIN IS TO HARDEN, COMPRISING THE COMBINATION OF (A) A SYRINGE FILLED WITH A LIQUID UNCATALYZED POLYESTER RESIN, THE SAID SYRINGE HAVING AN EXIT ORIFICE AND ATTACHMENT MEANS SURROUNDING SAID ORIFICE, AND (B) A TUBULAR CARTRIDGE CONTAINING AN ORGANIC PEROXIDE CATALYST FOR THE SAID RESIN AND A SOLIDIFYING AGENT, A DELIVERY TUBE AT ONE END OF THE CARTRIDGE, MEANS PROVIDED AT THE OPPOSITE END OF SAID CARTRIDGE TO CONNECT THE SAME TO THE ATTACHMENT MEANS OF SAID SYRINGE, AND MEANS TO FORM A PASSAGE THROUGH THE SAID CATALYST MASS WHEREBY, WHEN THE SAID SYRINGE AND THE SAID CARTRIDGE ARE JOINED, RESIN MAY BE FORCED THROUGH THE SAID PASSAGE AND ENTRAIN CATALYST DURING THE PASSAGE OF THE LIQUID RESIN FROM SAID SYRINGE TO THE SAID DELIVERY TUBE.

Claim 3
Dependent Claim
72 words
THE PROCESS OF MIXING A POLYMERIZATION CATALYST WITH A LIQUID RESIN WHICH INCLUDES, UNIFORMLY DISTRIBUTING THE CATALYST IN A SUSPENDING MEDIUM AND ALLOWING THE SUSPENSION TO SOLIDIFY, THEN PRIOR TO PLACING THE RESIN IN ITS FINAL POSITION, FORCING THE LIQUID RESIN THROUGH A PASSAGE FORMED IN THE CATALYST MASS, WHEREBY THE FLOW OF RESIN THROUGH SAID PASSAGE WILL REMOVE CATALYST MATERIAL FROM SAID CATALYST MASS AND PRODUCE A UNIFORMLY CATALYZED RESIN-CATALYST MIXTURE.
