Abstract
Abstract A uniquely constructed sensing apparatus is provided to 1. CONTINUOUSLY AND MORE ACCURATELY SENSE THE TEMPERATURE OF A HEATED RUBBER MATERIAL IN A MOLD THAN HAS HERETOFORE BEEN POSSIBLE, 2. REDUCE THE CURING TIME THAT HAS HERETOFORE BEEN REQUIRED TO HEAT A RAW RUBBER MATERIAL TO A CURED STATE AND TO 3. SENSE THE INSTANT OF TIME WHEN A HEATED RAW RUBBER MATERIAL BEING CURED IN A MOLD REACHES A CURED STATE AND THEREBY ELIMINATE THE COSTLY PRESENT PRACTICE OF OVERHEATING TO MAKE SURE THAT THE RUBBER MATERIAL IS PROPERLY CURED.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
A temperature sensing apparatus adapted for mounting in a curing mold to sense the temperature of the material being heated therein without the heat from said mold affecting the temperature being sensed by said apparatus, comprising two heat insulating members, the first one of said members having a wall forming a recess therein and a means to accommodate the positioning of an electrically conductive temperature sensing element in said first member and in spaced relationship from the wall forming said recess, the second of said insulating members having a rib positioned to protrude into said recess formed by said wall in said first member, said electrically conductive temperature sensing element having a temperature sensing end portion positioned between two common end portions of said insulating members that are insertable into said material, and a bushing positioned about and in contact with said members to retain them in fixed relationship with one another.
Claim 2
Dependent Claim
152 words
A temperature sensing apparatus adapted for mounting in a curing mold to sense the temperature of the material being heated therein without the heat from said mold affecting the temperature being sensed by said apparatus, comprising two heat insulating members, the first one of said members having a wall forming a recess therein and a means to accommodate the positioning of an electrically conductive temperature sensing element in said first member and in spaced relationship from the wall forming said recess, the second of said insulating members having a rib positioned to protrude into said recess formed by said wall in said first member, said electrically conductive temperature sensing element having a temperature sensing end portion positioned between two common end portions of said insulating members that are insertable into said material, and a bushing positioned about and in contact with said members to retain them in fixed relationship with one another.
Claim 3
Dependent Claim
152 words
A temperature sensing apparatus adapted for mounting in a curing mold to sense the temperature of the material being heated therein without the heat from said mold affecting the temperature being sensed by said apparatus, comprising two heat insulating members, the first one of said members having a wall forming a recess therein and a means to accommodate the positioning of an electrically conductive temperature sensing element in said first member and in spaced relationship from the wall forming said recess, the second of said insulating members having a rib positioned to protrude into said recess formed by said wall in said first member, said electrically conductive temperature sensing element having a temperature sensing end portion positioned between two common end portions of said insulating members that are insertable into said material, and a bushing positioned about and in contact with said members to retain them in fixed relationship with one another.
Claim 4
Dependent Claim
152 words
A temperature sensing apparatus adapted for mounting in a curing mold to sense the temperature of the material being heated therein without the heat from said mold affecting the temperature being sensed by said apparatus, comprising two heat insulating members, the first one of said members having a wall forming a recess therein and a means to accommodate the positioning of an electrically conductive temperature sensing element in said first member and in spaced relationship from the wall forming said recess, the second of said insulating members having a rib positioned to protrude into said recess formed by said wall in said first member, said electrically conductive temperature sensing element having a temperature sensing end portion positioned between two common end portions of said insulating members that are insertable into said material, and a bushing positioned about and in contact with said members to retain them in fixed relationship with one another.
Claim 5
Dependent Claim
44 words
The temperature sensing apparatus as defined in claim 1 wherein tapered ribs are formed along an outer surface of said insulating members and the inner surface of said bushing is of a tapered configuration to fixedly engage said outer surface of said tapered ribs.
Claim 6
Dependent Claim
74 words
The temperature sensing apparatus as defined in claim 1 wherein tapered ribs are formed on an outer surface of said insulating members, the inside surface of the bushing is constructed of a tapered configuration to fixedly engage said outer surface of said tapered ribs and to be held in a unitary relationship therewith and wherein one end of said bushing is retained in peened over relationship with an end portion of said tapered ribs.
Claim 7
Dependent Claim
42 words
The temperature sensing apparatus as defined in claim 1 wherein the outer surface of said bushing has threads formed thereon that are adapted to be inserted in fluid tight engagement with a bored out threaded wall which passes through the curing mold.
Claim 8
Dependent Claim
64 words
The temperature sensing apparatus as defined in claim 1 wherein the bushing and insulating members retained therein are constructed for insertion in any one of a number of angularly displaced positions in a wall forming a passageway through the curing mold while its associated temperature sensing end portion is simultaneously positioned at a similarly displaced location in the material being retained by said mold.
Claim 9
Dependent Claim
75 words
The temperature sensing apparatus as defined in claim 1 wherein the outer surface of the bushing is cylindrical and constructed for insertion in any one of a number of different selected angularly displaced positions in a bored out wall passing through said curing mold, and a mechanically adjusted means is employed between the bushing and the mold to retain the temperature sensing end portion in any one of said angularly displaced positions in said material.
Claim 10
Dependent Claim
33 words
The temperature sensing apparatus as defined in claim 1 wherein the surfaces of the two insulating members containing the recess and said rib are cemented in fixed fluid tight relationship with one another.
Claim 11
Dependent Claim
79 words
The temperature sensing apparatus as defined in claim 1 wherein the surfaces of the two insulating members containing the recess and said rib are cemented in fixed fluid tight relationship with one another and wherein a pair of adjacent ends of each of the two insulating members converge toward one another and toward an exposed part of the temperaturE sensing end portion to facilitate the insertion of the temperature sensing end portion into the material retained by said mold.
