Title: Microprocessor controlled liquid chemical delivery system and method
Inventor: TURNER JAMES R
IPC: B01F15/04
Filed: 1990-06-13
Granted: 1995-06-13
Abstract: A liquid chemical delivery system automatically delivers viscous chemicals to a number of destinations, such as a number of industrial clothes washers.   Several distinct chemicals are pumped, one at a time, into a manifold.  The chemical being pumped is mixed with water in the manifold and then transported through a distribution line to its specified destination.  By mixing the chemicals with water, viscous chemicals are diluted and delivered using a low pressure delivery system.  A single flow meter is used to calibrate  all  the  chemical  metering  pumps  and  to recalibrate  those  pumps  periodically,  thereby providing accurate chemical metering.  The manifold and distribution tube  are  automatically  flushed with water  after  every chemical  delivery  so  as  to  reduce  corrosion  and maintenance  costs.    In  addition,  potentially  reactive chemicals are kept separate from one another despite the use of only a single distribution line.  The system uses a proof-of-flow conductivity meter in the manifold to confirm the presence of each specified chemical in the manifold during  the  chemical  pumping  process.     Local proof-of-delivery  conductivity  meters  at  the  system's output ports are used to verify delivery of each chemical to the specified output port.

Granted: 1998-12-29
Abstract: The method of making polystyrene foam for foam products which comprises utilizing atmospheric gases as the blowing agents or preferably mixing one or more of these gases and a blending  agent  which  is  non-volatile  at  the  extrusion temperatures, introducing the mixture to a molten thermoplastic polystyrene resin containing nucleating agents such as sodium bicarbonate and citric acid and extruding the thermoplastic in the form of a foam.  The resultant foam has substantially no residual blowing agent,  is dimensionally stable at ambient temperatures and when used with a non-volatile blending agent can be made with small amounts of blowing agent permitting cooling of the melt without high loading on the extruder.  The foam may be coextruded with one or more layers of thermoplastic film so that the resultant product is adapted for use for plates, cups, food containers or packaging and for labels for containers such as glass and plastic containers and for labels that are shrunk in place on a container.
