Abstract: The instant disclosure provides a process for making spray dried compositions and a spray drying apparatus. A relatively small, compound spray dryer is provide with an appropriately sized aspect ratio of height to diameter to allow sufficient drying time for typically sized spray dried dispersion particles intended for solid dosage form applications. The dryer is further designed to provide an amount of drying recirculation that serves to rapidly mix incoming hot drying gas to eliminate hot regions on the dryer walls.

Abstract: A method and apparatus for battery cell temperature maintenance including determining a battery cell temperature of a battery cell is below a temperature threshold and initiating a temperature maintenance mode. Upon initiation of the temperature maintenance mode, determining a charge level of the battery cell and initiating one of a charge sequence in which the battery cell is charged and a discharge sequence in which the battery cell is discharged. The charge sequence initiated upon determining the charge level is equal to or less than a discharge limit and the discharge sequence initiated upon determining the charge level is equal to or greater than a charge limit.

Abstract: An improved door assembly includes a door frame having a door jamb and a door having a fixed portion including a hinged side and a locking side where the hinged side of the door is hinged to the door frame. At least one of the hinged side and the locking side of the door has at least one pivotable door portion configured to pivotably move between a retracted position inside the door and an extended position that extends inside at least one complementary shaped channel within the door jamb of the door frame to interlock the door and the door frame.
