Abstract: A multiple tank and pallet assembly comprising a rectangular pallet and four rectangular tanks arranged in a side-by-side confined cluster on the pallet enabling handling and transport of the pallet and tanks as a unit, individual tanks being removable from the assembly when desired. Each of the tanks is particularly constructed to facilitate discharge of the contents so that the assembly can be used to dispense four different liquids.

Abstract: A fluidized bed discharge bin comprises a removable closure covering an opening in the bottom of the bin. The interior surface of the closure is covered by an air-permeable sheet whose outer perimeter is held between the bin opening and the closure. Spacing means are disposed on the surface of the closure to space at least a portion of the air-permeable sheet from the closure. Aerating fluid is introduced into the bin via an inlet in the closure which is located in close proximity to the location where the spacing means is spacing the air-permeable sheet from the interior surface of the closure. The aerating blower system includes a control for supplying aerating fluid to the bin in the form of successive aerating pulses and provision is made for causing an initial surge of pressure to be imparted to the beginning of each aerating pulse which is greater than the nominal aerating pressure. Plural embodiments of the invention are disclosed.
