The present invention is generally directed to a method of controlling a pyrolytic carbon deposition coating process performed in a fluidized bed. In one illustrative embodiment, the method comprises positioning a product to be coated in the fluidized bed, determining a coating rate of carbon material formed on the product in the fluidized bed, and determining a desired duration of the coating process by dividing a desired coating thickness for the product by the determined coating rate.

Method for determining product coating rates for fluidized beds

A method and apparatus for treating and preventing arteriosclerosis includes a magnet located inside the human body adjacent an artery. The magnet generates magnetic flux through the artery. At least a portion of the magnetic flux has a component perpendicular to the direction of blood flow through the artery.

Method and apparatus for treating and preventing arteriosclerosis

A fluidized bed apparatus which produces a pyrolitic carbon coating with improved wear and porosity characteristics of the coating by producing a more uniform flat temperature profile throughout a reaction chamber in the area where coating is taking place. The apparatus has heating coils surrounding a lower end of the reaction chamber placed immediately adjacent one another at tight spacing. This contrasts to previous apparatus wherein heating coils were spaced between 2 cm and 5 cm apart. The apparatus also has a multi-jet nozzle to control a flow of gases through the reaction chamber. The jets in the nozzle comprise passages which are oriented such that the length of the passages lie on a series of cones having common axes.
