Abstract

552,630. Degassing liquids. THOMPSON PRODUCTS, Inc. Feb. 28, 1942, No. 2658. Convention date, Sept. 5, 1941. [Class 1 (i)] [Also in Group XXVI] A pump suitable for boosting the supply of gas free fuel to aircraft at high altitudes comprises a centrifugal pump 28, 29 drawing fuel from a tank 10, and having on the pump shaft agitating means such as a screw pump 31 for beating out gases from the fuel before it enters the inlet eye of the pump 28. The eye is carried by a plate 22 which supports a funnel 26 inside which the fuel flows to the pump while outside the separated gases rise to the surface of the fuel in 10. In another form, the impeller has blades which taper towards the centre of the impeller, and carries a conical agitator projecting into the eye of the pump. In another form, the agitator is a centrifugal impeller which receives the fuel from the tank and forces the degassed liquid to the eye of the pump arranged below it. In another form, the fuel flows to the eye through a vertical cylinder in the tank, while the separated gases flow upwards outside it, and the impeller blades have portions projecting up into the eye to agitate the fuel In another form the fuel flows to the agitator fan through a funnel carried inside a cylindrical strainer ; in another the impeller carries a number of arms sweeping over the upper flared surface of the eye; and in another a number of small blades are mounted on the upper end of the impeller shaft to agitate the fuel. Specification 548,383, [Group XXVI], is referred to.
