Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
53 words
Apparatus comprising: a heater; a separate heat conducting member engagable with said heater; a plurality of rigid, spaced-apart heat conducting projections extending from said heat conducting member; and an elastomeric pad molded over said projections; whereby heat is transmitted from said heater assembly to said plate and projections, thereby heating said elastomeric pad.
Claim 2
Dependent Claim
53 words
Apparatus comprising: a heater; a separate heat conducting member engagable with said heater; a plurality of rigid, spaced-apart heat conducting projections extending from said heat conducting member; and an elastomeric pad molded over said projections; whereby heat is transmitted from said heater assembly to said plate and projections, thereby heating said elastomeric pad.
Claim 3
Dependent Claim
17 words
Apparatus of claim 1, further comprising: a plurality of heat generating elements removably disposed within said heater.
Claim 4
Dependent Claim
24 words
Apparatus of claim 1, wherein said plate is provided with a fill hole through which liquid elastomeric compound is introduced to fill a mold.
