Embodiment 1
[0076] According to various aspects of the invention, a high temperature TCO device is formed as follows. Thermal pellets are formed by combining 980 g to 1000 g of triptycene (commercially available from Sigma-Aldrich manufacturer, 95-99% pure) with 20 g to 0.5 g of colorant, binder and / or mold release agent mix. The homogenized mixture was processed on a standard powder compaction press (commonly available from pharmaceutical equipment suppliers). Powder is fed through a gated powder flow control system and evenly distributed over the rotating die table. The mold is filled with the powder and the powder in the mold is punched under a pressure of about 1 to 4 tons to form compacted powder pellets having a density of 29 to 50 pellets / gram. The thermal pellets were placed into a highly conductive metal closed-end cylinder with an inner diameter close to the outer diameter of the TCO thermal pellets. The closed end of the barrel is staked shut with axial conductive metal lead...
