Abstract
Abstract A heated tool comprises a one piece tool member having a plurality of bar portions with different cross sections. A single current path is defined through the bar portions for heating various areas of the bar portions to different extents. Advantageously, one or more U-shaped heating bars can be defined in the single tool member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
A heated tool for heating at least one object, comprising a plurality of contiguous current passing bar portions defining a contiguous path for the resistive heating of at least some of the bar portions, at least some of said bar portions having different cross sections for passing different amounts of current and being resistively heated by different amounts, at least one of said bar portions comprising an connecting bar portion having a relatively large cross section, and at least one of said bar portions comprising a heating bar portion having a relatively small cross section, said heating bar portion carrying a heating surface lying in a plane which is offset by a selected spacing from said connecting bar portion whereby said connecting bar portion acts as a relatively cool holding device for a component to be heat treated by said heating surface.
Claim 2
Dependent Claim
142 words
A heated tool for heating at least one object, comprising a plurality of contiguous current passing bar portions defining a contiguous path for the resistive heating of at least some of the bar portions, at least some of said bar portions having different cross sections for passing different amounts of current and being resistively heated by different amounts, at least one of said bar portions comprising an connecting bar portion having a relatively large cross section, and at least one of said bar portions comprising a heating bar portion having a relatively small cross section, said heating bar portion carrying a heating surface lying in a plane which is offset by a selected spacing from said connecting bar portion whereby said connecting bar portion acts as a relatively cool holding device for a component to be heat treated by said heating surface.
Claim 3
Dependent Claim
22 words
A tool according to claim 1 wherein at least some of said bar portions have different mechanical dimensions and different thermal masses.

Claim 5
Dependent Claim
103 words
A heated tool for heating at least one object, comprising a plurality of contiguous current passing bar portions defining a contiguous path for the resistive heating of at least some of the bar portions, at least some of said bar portions having different cross sections for passing different amounts of current and being resistively heated by different amounts, said plurality of contiguous bar portions being formed as a single one piece mechanical unit; and a plurality of slots cut into said unit and defining at least two heating bar portions therebetween, each heating bar portion carrying a heating surface for heating an object.
