e very numerous, having reference mainly to detail: to regulate the admission of air, the egress of carbureted air, the graduation of the quantity of liquid admitted, a forced circulation in the carbureting chamber; to regulate the temperature of the liquid, the air, and the result; means for drawing off the heavy oil.
As means of forcing the air: —
Bassett and McAvoy use the weighted gas-holder, the inverted cylinder whose lower edge is immersed in the water of an annular chamber.
Prichard forced the air by water under pressure, admitted below to expel the air from the chamber.
Douglas's has a rotary fan.
Levi Stevens's has a meter-wheel, whose shaft has its bearing below the center of the partition dividing the meter and regulation chambers, and gears with a wheel on the regulator-shaft, which has a bearing at the center of the partition.
Both chambers are partially filled with carbureting liquid.
Air is introduced to the top of the meter-chamber.
