Abstract:
A dispenser system employs a packaging module for use with moisture sensitive materials. The packaging module comprises an outer carton and an inner bladder, which is substantially impermeable to moisture and is filled with one part of an adhesive. The carton is loaded on a mobile cart and the one part adhesive is supplied to a pump/mixer without exposure to moisture in the atmosphere. The packaging and dispensing system can be used in conjunction with mechanized adhesive application equipment for the construction trades.

Abstract:
The instant invention discloses a method of generating silicon powder aerosol to maintain cleanliness of the silicon powder during the feed process which utilizes an carrier gas, optionally, inert, and non-contaminating feed line to a plasma spray gun.
Abstract:
Apparatus for melting and dispensing very high viscosity material, such as butyl. A chamber with heated walls is provided with an internal conveyor and pump near the bottom wall of the chamber. The conveyor has sections which transfer rotational energy to material within the chamber, dragging high viscosity material to a pump inlet hole in the bottom wall of the chamber. Deflection plates mounted within the chamber push material down onto the conveyor, so that pump suction can be maintained. The plates also promote vertical as well as horizontal material mixing, thereby exposing new surfaces of the thermoplastic material to the heated walls of the chamber, increasing the rate of heat transfer from the walls to the material.
Abstract:
A device for dispensing liquids such as paint, lacquer, glue and the like containing solvents which evaporate in air at room temperature, includes an outer rigid shell forming an enclosure for an inner flexible bag or container. The bag has an outlet orifice coincident with an outlet opening provided in the bottom wall of the outer shell, and an air inlet communicates with the interior of only the enclosure for establishing an atmospheric pressure therewithin so as to permit the dispensing liquid to flow outwardly of the outlet opening. The outlet may be closed by a shut-off valve so as to create a sub-atmospheric pressure level within the enclosure to thereby interrupt the liquid flow from the device. Otherwise, the air inlet may be closed when its outer end becomes submerged in a quantity of water contained within a receptacle and divided by a flexible diaphragm from the dispensed liquid. The water level changes in response to changes in the supply of dispensing liquid in the receptacle as an applicator roll coats products with the dispensed liquid.
Abstract:
A convenient and efficient paint tank which utilizes water pressure as the pressure means for dispensing paint from the tank through the application device. More specifically a paint tank having an upper and lower chamber separated by a flexible diaphram. Paint and the like is introduced into the upper chamber by way of an access port and water is introduced into the lower chamber by a hose. The water induces a pressure against the diaphram forcing the paint out of the upper chamber and through a valve to the application device. Further, a way of introducing water into the upper chamber is also provided such that the tank will clean itself when the paint has been removed.
Abstract:
Method and apparatus for agitating an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material are disclosed. Movable vanes are disposed beneath the surface of a bath of the composition. The vanes have a relatively large surface area and are moved through the bath at low speed so that the shear stress imposed on the dispersed particles is minimized. This prolongs the stability of the composition.
