Abstract: An improved apparatus is disclosed for controlling the flow of liquid fuel through a feed tube onto the convex exterior surface of an atomizer bulb of the Babbington type. Liquid fuel is directed into a deaeration chamber (50) having a suitable baffle for separating entrained air and dissipating dynamic flow effects. The inlet (64) of the feed tube for the atomizer bulb is positioned at the lower end (54) of the deaeration chamber so that as the chamber fills with liquid fuel, any air in the feed tube is quickly flushed. The upper end of the deaeration chamber is closed and provided with an inlet (56, 104) to a conduit (58). An adjustment (62; 72-88; 90-126) is provided to permit variation of the flow through the suction conduit and, hence, variation of the flow over the atomization bulb.

Abstract: An optical concentrator and cooling system in which a photovoltaic cell array is immersed in a liquid inside an elongated tube having a curved transparent wall for incident radiation, said liquid having a refractive index suitable for concentrating the incident radiation onto the photovoltaic cell array.
