Abstract
Abstract A process and an implement for converting microwave energy into heat energy which includes a body having a plurality of resistive particles therein. Upon subjecting the particles to microwave irradiation, a plurality of electric arcs are generated throughout the particles, thereby resulting in the microwave energy being converted into heat energy, and the electric arcs serving as a load for the microwave irradiation source. The implement is particularly useful with microwave ovens.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
In combination, means defining an oven cavity, a source of microwave energy connected to said cavity, an implement in said cavity, comprising: a body permeable to microwave energy, said body containing a plurality of resistive particles so disposed, which when exposed to microwave irradiation, results in a multitude of arcs being generated therethrough so as to convert said microwave irradiation into heat energy.
Claim 2
Dependent Claim
63 words
In combination, means defining an oven cavity, a source of microwave energy connected to said cavity, an implement in said cavity, comprising: a body permeable to microwave energy, said body containing a plurality of resistive particles so disposed, which when exposed to microwave irradiation, results in a multitude of arcs being generated therethrough so as to convert said microwave irradiation into heat energy.
Claim 3
Dependent Claim
16 words
In an oven, cavity, according to claim 1, wherein said microwave permeable body is electrically insulated.
Claim 4
Dependent Claim
17 words
In an oven cavity, according to claim 1, wherein the resistive particles are of a ferrite material.
Claim 5
Dependent Claim
50 words
In an oven, according to claim 1, wherein the implement further includes a heat conducting element having at least one opening therein for permitting the passage of microwave irradiation to the resistive particles to load the microwave emitting means and to permit an equal distribution of heat for a workload.
Claim 6
Dependent Claim
33 words
In an oven, cavity, according to claim 2, wherein the implement is provided with at least one surface forming a shelf and said cavity is provided with means for adjustably supporting said body.
Claim 7
Dependent Claim
144 words
In an oven, according to claim 5, wherein the cavity contains a second said implement supported by said adjustably supporting means. 7. In a microwave oven having a shelf and means for emitting microwave energy into said oven, the improvement in said shelfing comprising: a first member of a microwave permeable material shaped to conform to the interior perimeter of the cavity with which it is to be used, a second member of a microwave absorptive material, and a plurality of rods of a heat conducting material embedded within the second member and arranged in a preselected pattern which will convey the heat generated within the material of said second member in the presence of microwave energy to an oven load, said second member and said rods being so disposed that the heat generated within said absorptive material is conducted to said first member.
Claim 8
Dependent Claim
65 words
An implement for heating an article for use in an oven chamber receptive to microwave radiation comprising, a first member of a microwave permeable material, a second member of a microwave absorptive material, and a heat conducting member in a preselected relationship with said second member for conducting the heat generated by said second member in the presence of microwave energy to said first member.
Claim 9
Dependent Claim
65 words
An implement for heating an article for use in an oven chamber receptive to microwave radiation comprising, a first member of a microwave permeable material, a second member of a microwave absorptive material, and a heat conducting member in a preselected relationship with said second member for conducting the heat generated by said second member in the presence of microwave energy to said first member.
Claim 10
Dependent Claim
17 words
An implement, according to claim 1, wherein a portion of said body is of heat insulating material.
Claim 11
Dependent Claim
22 words
An implement, according to claim 9, wherein said body includes means for supporting an article in heat conducting relationship with said particles.
Claim 12
Dependent Claim
12 words
An implement according to claim 10, wherein said means is a grill.
