A mixing and atomizing nozzle is disclosed which has a first or inner orifice which directs a thin film of gas outwardly and expands the same to supersonic speed for subsequent transition to subsonic speed over a deflector member or mandrel, together with first and second orifices which are positioned adjacent each other and immediately outwardly of the first orifice for applying thin films of first and second liquids for mixing and atomization.

Mixing nozzle

A hot melt pumping and dispensing apparatus for heating and pumping a heat liquefiable product from a barrel includes a platen movable into the barrel and having a plurality non-perforated, sector-shaped cast heater segments, each provided with an electric heater, arranged in a circle on the lower face of the platen and having inner ends defining a central space at a common apex thereof. The segments are spaced from each other to define narrow radial passageways between adjacent segments opening into the central space for delivery of liquefied product thereinto. A cartridge-type pump carried by the platen communicates with the central space. The lower face of each heater segment is provided with depending heat conducting cylindrical projections which extend in advance of the segments into the product in the barrel to preheat and soften the product. The segments may each have a truncated inner end or may each be pointed and have a truncated upper portion spaced radially outwardly of the point for defining the central space.

Hot melt dispenser

A dispenser, such as for a hot melt material, incorporates a platen which is movable into a container of material to be dispensed and incorporates a cartridge-type gear pump positioned centrally of the platen. The platen is carried on a support tube and the lower end of the support tube is provided with an opening through which the cartridge gear pump may be inserted or removed from the platen without the necessity of otherwise disturbing the platen.
