Abstract: A video inspection system for hazardous environments is provided, comprising a housing, sealable so as to contain a pressurized gas therein, having a view opening therein and further including a valve for introducing pressurized gas into the housing, connected to the housing; and a transparent lens, sealingly affixed across the view opening; a camera for recording visual images through the view opening, mounted within the housing; and a power supply, for powering the camera, mounted within the housing and operatively connected to the camera. A method for operating the above system is also provided, including the steps of substantially purging undesirable gases from the interior of the housing; sealing the housing, eliminating external connections thereto; introducing non-flammable gas to the interior of the housing until the pressure in the housing reaches a desired level; and operating the camera within the housing.

Abstract: A solid or semi-solid fuel produced entirely from vegetable products having an approximate formulation of 86.1% ethanol, 2.2% water and 11.7% sodium salts of fatty acids produced by virtually any commercially available process for producing ethanol from vegetable crops such as cane sugar, beet sugar, wheat, pineapple, corn and the like which also produces "sweetwater" which contains fatty acids, sugar water and fibrous plant material in which the sweetwater is mixed with the ethanol in a reactor which heats the mixture to a temperature of 110-140 degrees fahrenheit wherein the mixing is performed in two stages by two reactors in which the first reactor rotates at between 750-1800 r.p.m. for from five to seven minutes and the second reactor rotates at between 2200-3100 r.p.m. for about five to seven minutes.
