Abstract: The present disclosure relates to a spray head assembly for a beverage making machine comprising a mounting for connection to a flow of liquid from a reservoir or other water source and a surface for joining to a spray head. A face portion of the spray head has an interior surface with relative rises and depressions or hills and valleys. Orifices are located generally at the peak of a hill with valleys being defined between neighboring hills.

Abstract: An apparatus and method of dispensing a partially frozen beverage. The apparatus includes at least one beverage hopper for retaining a quantity of partially frozen beverage. The beverage hopper has a dispensing aperture formed therein and a guide member in an exterior surface of the beverage hopper. A chilling unit cools the partially frozen beverage retained within the beverage hopper. A dispenser assembly is provided which includes a handle, a biasing element, a gasket and a slideable valve member. the valve member has a portion dimensioned to slideably engage the guide member of the beverage hopper.

Abstract: An external combustor for a gas turbine engine has a cyclonic combustion chamber into which combustible gas with entrained solids is introduced through an inlet port in a primary spiral swirl. A metal draft sleeve for conducting a hot gas discharge stream from the cyclonic combustion chamber is mounted on a circular end wall of the latter adjacent the combustible gas inlet. The draft sleeve is mounted concentrically in a cylindrical passage and cooperates with the passage in defining an annulus around the draft sleeve which is open to the cyclonic combustion chamber and which is connected to a source of secondary air. Secondary air issues from the annulus into the cyclonic combustion chamber at a velocity of three to five times the velocity of the combustible gas at the inlet port. The secondary air defines a hollow cylindrical extension of the draft sleeve and persists in the cyclonic combustion chamber a distance of about three to five times the diameter of the draft sleeve.
