Patent ID: 8017076

Claim:
A direct-heating reaction disc arrangement comprising: a reaction disc body, a plurality of clampers, a heater, and a driving plate, wherein the reaction disc body comprises holding slots for receiving reaction cups, the plurality of clampers are mounted under a bottom surface of the reaction disc body, and each of the plurality of clampers comprises an upper clamper and a lower clamper both of which are mounted under the bottom surface of the reaction disc body, the heater is sandwiched between the upper clamper and the lower clamper configured to improve conductive heat transfer to the reaction disc body and the reaction cups through at least the upper clamper, at least a portion of a bottom surface of at least one of the reaction cups directly contacts an upper surface of the upper clamper with the lower clamper to sandwich the heater for the improved conductive heat transfer from the heater through at least the upper clamper to the reaction cups, and the driving plate is mounted to one or more supporting flanges of the reaction disc body for receiving a power supply to drive the reaction disc body, wherein the one or more supporting flanges are part of an integral and inseparable structure of the reaction disc body configured to support or secure the driving plate to the reaction disc body.
