Abstract
Abstract An apparatus employing directed infrared radiation emitted by two spaced sources delimiting a baking space for a plate receiving food to be baked. The two sources are separated by a space of 5 to 10 centimeters. The lower source is preferably located less than one millimeter from the bottom of the support, which is constituted by a circular removable plate. The plate is supported and guided rotationally with respect to the floor of the apparatus and is made of an infrared-permeable material and cooperates by its periphery with a constant-speed positive rotational drive arrangement. The drive confers a sequential character on the strong radiation energy of the infrared sources.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
An apparatus for baking flat foods, comprising: an upper and a lower rectilinear source of infrared radiation, said sources being separated by a space between 5 and 10 cm; a support means for supporting the food to be baked, said support means being a rotatably supported removable plate disposed between said upper and lower sources, wherein said plate is made of an infrared-permeable material and is disposed less than 1 mm above said lower source, wherein said upper and lower infrared radiation sources are displaced on either side of a median vertical plane passing through the plate diameter with which their respective lengthwise axes are parallel, and wherein each of said infrared sources is designed to furnish infrared radiation that increases starting from its midpoint out to each of its ends extending beyond the plate; a constant speed positive rotational drive means for rotating said plate thereby conferring a sequential character on the infrared source radiation energy; and a roof and a floor, said upper and lower sources being disposed between said roof and said floor in reflecting gutters respectively provided in said roof and said floor.
Claim 2
Independent Claim
187 words
An apparatus for baking flat foods, comprising: an upper and a lower rectilinear source of infrared radiation, said sources being separated by a space between 5 and 10 cm; a support means for supporting the food to be baked, said support means being a rotatably supported removable plate disposed between said upper and lower sources, wherein said plate is made of an infrared-permeable material and is disposed less than 1 mm above said lower source, wherein said upper and lower infrared radiation sources are displaced on either side of a median vertical plane passing through the plate diameter with which their respective lengthwise axes are parallel, and wherein each of said infrared sources is designed to furnish infrared radiation that increases starting from its midpoint out to each of its ends extending beyond the plate; a constant speed positive rotational drive means for rotating said plate thereby conferring a sequential character on the infrared source radiation energy; and a roof and a floor, said upper and lower sources being disposed between said roof and said floor in reflecting gutters respectively provided in said roof and said floor.
Claim 3
Dependent Claim
106 words
The apparatus according to claim 1, wherein said plate is rotatably supported by a plurality of stepped rollers having first and second stepped surfaces, said rollers adapted to freely rotate about axes that are horizontal and radial relative to said plate, said axes being spaced angularly and supported by fixed bearings each of said rollers being disposed such that said first stepped surface is arranged above said floor by said predetermined distance and said second stepped surface is arranged radially outside of said first stepped surface and constitutes a stop for holding a peripheral edge of said plate, said plate resting on said first stepped surface.
Claim 4
Dependent Claim
48 words
The apparatus according to claim 1, wherein said drive means further comprises an electric motor having an output shaft disposed radially relative to the plate, and a gear attached to said output shaft cooperating with a plurality of circular teeth integral with a peripheral edge of said plate.
Claim 5
Dependent Claim
48 words
The apparatus according to claim 3, wherein said electric motor and said infrared radiation sources are connected to an electrical circuit comprising a timer, means for setting the radiation power of each of said sources, and safety means for switching off said sources if said electric motor fails.
Claim 6
Dependent Claim
90 words
The apparatus according to claim 4, wherein the safety means comprises a wiper in contact with the plate and integral with an oscillating lever, said lever being urged from a resting position towards a control tongue of a cutoff contactor by rotation of said plate, said lever being urged away from said control tongue by a return spring towards said resting position such that when rotation of said plate is interrupted, said spring causes said lever to return to said resting position releasing said control tongue from said cutoff contactor.
Claim 7
Dependent Claim
29 words
The apparatus according to claim 1, wherein said roof has a front cutaway for access to said plate, said cutaway extending essentially to half the depth of said plate.
Claim 8
Dependent Claim
26 words
The apparatus according to claim 1, wherein said lower infrared source, said plate, and said drive means are disposed on a frame forming a removable drawer.
