Abstract: A viscous fluid pumping system having a pair of opposing gears (130, 132) is provided in a housing (32) disposed above an inlet port (73) in a follower plate (70). The follower plate (70) is dimensioned to sealingly fit in a container or drum (D) filled with highly-viscous fluid. In operation, the gears generate a vacuum between the follower plate (70) and the viscous fluid, allowing atmospheric pressure to press the follower plate into the viscous fluid. This, in turn, forces the fluid through the inlet port (73) and into the gears (130, 132). The gears exert high shear forces and localized heating to the fluid, decreasing its viscosity. The fluid exits the system through an outlet in the gear housing. The pumping system may use two such pumps working in conjunction or incorporate a single such pump with a valve structure for recycling fluid through itself.

Stream parts 10, 11 and 12 may be separated by partition on approach to the pump gear and also by partitions 8 and 9 in the pump 1 itself.

Abstract: A gas/liquid mixer in which intermeshing gears are caused to rotate and establish mixing, by pressure of the fluids being mixed. The gears are mounted for rotation in a gear chamber and interengage in a meshing zone of the chamber. A gas is introduced into the chamber through a gas inlet which is adjacent to one end of the meshing zone. A liquid inlet enters the chamber between the gas inlet and an outlet which is positioned adjacent a second or opposite end of the mixing zone. The gears are rotated in the chamber by the introduction and expansion of the gas and liquid in the spaces between the gear teeth. Flow regulating means controls the gas/liquid ratio. The apparatus is useful, among other purposes, for mixing a soluble gas with molten hot melt adhesive, directly adjacent the nozzle of a dispenser for preparing a hot melt foam.

Abstract: A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion. In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pumping cavity between the liquid inlet and the outlet, and which are positioned to be "wiped" by the gear teeth as the gears rotate. The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.

Abstract: A gear pump is modified by the incorporation of a hollow rod means to permit a liquid additive to be injected into the gear pump at the point at which the gear wheels separate. At this point the pressure is at or below atmospheric pressure and, as a result, the additive can be added uniformly and independently of the pumped liquid flow and pressure.
