Abstract: A movable heat applicator is provided that is configured to treat a citrus tree for a bacterial disease. The heat applicator includes a heat containment structure that at least partially enclose a citrus tree. A steam generator adapted to produce steam is provided to release steam at a desired pressure and temperature for treating the citrus tree. A steam dispenser is connected to the steam generator and may be arranged in the interior of the heat containment structure at a positioned to dispense steam below branches of the citrus tree. The steam is dispensed into the heat containment structure to create a steam heated treatment environment to treat the bacterial disease. The movable heat applicator may also include a chassis coupled with the heat containment structure and a drivetrain that supports the chassis over a ground surface for moving the containment structure.

Abstract: A mold of a casting machine is filled to make a cast article. The method includes providing a molten metal to a casting chamber in fluid communication with the mold, the casting chamber having a supply conduit for introducing a gas into the casting chamber, and the casting chamber having an evacuation conduit for delivering the molten metal from the casting chamber to the mold. The method also includes controlling the filling of the mold during a first time interval by delivering the molten metal from the casting chamber to the mold at a first rate. The method further includes controlling the filling of the mold during a second time interval by delivering the molten metal from the casting chamber to the mold at a second rate. The filling of the mold decelerates from the first rate to the second rate and the second rate does not exceed the first rate.

Abstract: A method for producing a cast article comprising the steps of: (a)providing a casting apparatus having a mold, a casting chamber containing a molten metal under pressure and a fluid under pressure, the casting apparatus having a first supply port for supplying the molten metal to the casting chamber and a second supply port for supplying the fluid to the casting chamber; (b) supplying the molten metal to the first supply port; (c) supplying the fluid to the second supply port; (d) determining the amount of the molten metal in the casting chamber as a variable V1; (e) determining the amount of the fluid in the casting chamber as a variable V2; (f) determining the amount of humidity in the casting chamber as a variable V3; (g) determining the amount of the fluid entering the casting chamber as a variable V4; (h) determining the pressure of the fluid in the casting chamber as a variable V5; (i) determining the amount of the molten metal needed to produce a cast article in the mold as a variable V6; (j) determini
