Abstract
Abstract Disclosed herein is an insertable article for altering the cure rate and chemical composition of an object thus pierced which includes an elongated shaft, preferably formed from heat conductive material, and recesses extending along the length of the shaft provided with areas around the recess for the disposition of chemicals therein. The shaft has a terminus which is pointed for ease in insertion into the object, and the support areas and recesses are so disposed on an outer face of the shaft that the cure rate of the article and its chemical configuration is altered by a gradual leaching outwardly of the chemicals and a cure rate pattern altered by the heat conductive shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
An insertable article for altering the cure rate and chemical composition of an object comprising in combination: an elongate shaft, recess means along the length of said shaft provided with support areas for carrying chemicals therein, said shaft having one pointed terminus for facile insertion into the object, said support areas and recess means communicating without said shaft whereby chemicals disposed therein gradually leach out into the object wherein said recess means comprise a spiral groove (5) running the length of said shaft around said shaft and wherein said support areas comprise pockets (4) along side edges of said groove, above and below, and having openings (6) facing said groove and wherein said pockets have a circular configuration in section with an open arc area facing said groove and a shoulder extending to edge portion of said groove, and linear with an outer periphery of said shaft to protect against displacement of the chemicals upon insertion, removal, or rotation of said shaft, and wherein said support area are coextensive with said groove and similarly follow a spiral path.
Claim 2
Dependent Claim

An insertable article for altering the cure rate and chemical composition of an object comprising in combination: an elongate shaft, recess means along the length of said shaft provided with support areas for carrying chemicals therein, said shaft having one pointed terminus for facile insertion into the object, said support areas and recess means communicating without said shaft whereby chemicals disposed therein gradually leach out into the object wherein said recess means comprise a spiral groove (5) running the length of said shaft around said shaft and wherein said support areas comprise pockets (4) along side edges of said groove, above and below, and having openings (6) facing said groove and wherein said pockets have a circular configuration in section with an open arc area facing said groove and a shoulder extending to edge portion of said groove, and linear with an outer periphery of said shaft to protect against displacement of the chemicals upon insertion, removal, or rotation of said shaft, and wherein said support area are coextensive with said groove and similarly follow a spiral path.
Claim 3
Dependent Claim
40 words
The device of claim 1 wherein said shaft is formed from heat conductive material to accelerate the curing process of the object proximate to its inserted position thereby influencing and altering the overall cure pattern and gradient of the object.
Claim 4
Dependent Claim
12 words
The device of claim 2 wherein said shaft is formed of aluminum.
Claim 5
Dependent Claim
22 words
The device of claim 1 wherein said shaft has a handle means at an extremity remote from said pointed terminus, threaded thereon.
Claim 6
Dependent Claim
11 words
The device of claim 4 wherein said handle is heat conductive.
Claim 7
Dependent Claim
41 words
The device of claim 1 wherein plural shafts extend from a support base threadedly engaging apertures in said base, thereby forming an array whereby when an object to be treated is disposed thereon, larger areas of the object can be effected.
Claim 8
Dependent Claim
12 words
The device of claim 6 wherein said base is non heat conductive.
