Abstract: In a continuous process for drying a sludge composed of combustible material and water, the wet sludge is first mixed with a proportion of material which has been dried in the process and is then fed into a hot gas stream from a burner. The hot gas stream carries the mixture along and dries it, and a proportion is tapped off and mixed with the incoming wet sludge. A part of the remainder is fed, with supplementary fuel, if necessary, to the burner to create the hot gas stream. The rate of fuel supply is varied in dependence on a temperature of the hot gas stream when it exhausts from the mixture drying operation.

Abstract: This patent discloses a shield for an automatic transmission used in race cars radial that includes a strengthened fluid pan and a formed metal jacket shield that extends around the section of the housing of the transmission adjacent to the fluid pan from opposite sides of the fluid pan. The strengthened fluid pan is constructed to extend outwardly from the transmission housing to provide locations at which the jacket shield may be secured to the fluid pan and to increase the volume of the fluid pan as compared to conventional fluid pans. The jacket shield is secured directly to the fluid pan and in combination with the fluid pan provides a shield that continuously surrounds the transmission and resists perforation and separation due to impact of fragments propelled from the transmission after breakage of rotating components of the transmission.
