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.
Claim 5
Dependent Claim 13 words
Apparatus of claim 1, wherein said heat conducting member is a metal plate.
Claim 6
Dependent Claim 28 words
Apparatus of claim 4, wherein said plate and heater are provided with beveled edges, whereby said plate is slideably engaged in close abutting conformity with said heater assembly.
Claim 7
Dependent Claim 20 words
Apparatus of claim 5, further including: at least one set screw of maintaining said plate in engagement with said heater.
Claim 8
Dependent Claim 12 words
Apparatus of claim 1, wherein said projections are bolts with enlarged heads.
Claim 9
Dependent Claim 16 words
Apparatus of claim 1, wherein said pad is composed of a compound resistant to heat degredation.
Claim 10
Dependent Claim 13 words
Apparatus of claim 1, wherein said pad is composed of a silicone compound.
Claim 11
Dependent Claim 13 words
Apparatus of claim 1, further comprising: a temperature sensor cooperative with said heater.
Claim 12
Dependent Claim 13 words
Apparatus of claim 1, further comprising: a temperature sensor cooperative with said pad.
Claim 13
Dependent Claim 14 words
Apparatus of claim 1, further comprising: a heat insulating layer cooperative with said heater.
Claim 14
Dependent Claim 76 words
Apparatus for heat transfer labelling, comprising: a mounting assembly; a heat insulating layer in overlaying conformity with said mounting assembly; a second assembly in overlaying conformity with said insulating layer, and having a plurality of elongated holes therein; a plurality of heat generating elements disposed within said holes; a plate having an aperture slideably engagable with said second assembly; a plurality of elongated projections extending from said plate; and a silicone pad molded over said projections.
Claim 15
Dependent Claim 76 words
Apparatus for heat transfer labelling, comprising: a mounting assembly; a heat insulating layer in overlaying conformity with said mounting assembly; a second assembly in overlaying conformity with said insulating layer, and having a plurality of elongated holes therein; a plurality of heat generating elements disposed within said holes; a plate having an aperture slideably engagable with said second assembly; a plurality of elongated projections extending from said plate; and a silicone pad molded over said projections.
Claim 16
Dependent Claim 19 words
Apparatus of claim 13, further comprising: a set screw for maintaining said plate in engagement with said second assembly.
Claim 17
Dependent Claim 9 words
Apparatus of claim 13, wherein said projections are bolts.
