Method and System for Switching a Dispensed Fluid in a Nanofabrication Dispensing System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18064798 titled 'Method and System for Switching a Dispensed Fluid in a Nanofabrication Dispensing System

Simplified Explanation: The patent application describes a method for switching a first fluid with a second fluid in a dispenser system without mixing the two fluids.

  • The method involves stopping the flow of the first fluid into a common portion of the system.
  • A flush fluid is then used to clean out the common portion before the second fluid is introduced.
  • The first fluid is continuously circulated to and from a reservoir without entering the common portion.

Key Features and Innovation:

  • Method for switching fluids in a dispenser without contamination.
  • Use of a flush fluid to clean out the system.
  • Continuous circulation of the first fluid to prevent mixing.

Potential Applications:

  • Industrial dispensing systems.
  • Chemical processing plants.
  • Pharmaceutical manufacturing.

Problems Solved:

  • Prevents contamination of fluids in dispensing systems.
  • Ensures clean and accurate fluid switching.
  • Reduces the risk of cross-contamination.

Benefits:

  • Improved accuracy in fluid dispensing.
  • Enhanced cleanliness in fluid switching processes.
  • Reduced waste of fluids.

Commercial Applications:

  • Precision dispensing equipment for various industries.
  • Fluid handling systems for pharmaceutical companies.
  • Automated dispensing systems for chemical manufacturing.

Prior Art: Prior art related to this technology may include patents or research on fluid switching methods in dispensing systems, as well as patents on fluid cleaning processes in industrial settings.

Frequently Updated Research: Research on advancements in fluid handling technologies, automated dispensing systems, and contamination prevention methods in industrial processes may be relevant to this technology.

Questions about Fluid Switching Technology: 1. How does this method compare to traditional fluid switching techniques in dispensing systems? 2. What are the potential cost savings associated with implementing this fluid switching method in industrial applications?


Original Abstract Submitted

A method of switching a first fluid supplied to a dispenser with a second fluid. The method includes stopping the first fluid from flowing into a common portion of a flow system, causing a flush fluid to flow through the common portion, stopping the flush fluid from flowing into the common portion, removing the flush fluid from the common portion, causing the second fluid to flow through the common portion, and continuously circulating the first fluid to and from a reservoir without the first liquid entering the common portion of the flow system. The continuously circulating of the first fluid begins a) after stopping the fluid liquid from flowing into the common portion of the flow system and b) prior to or during the second fluid flowing through the common portion of the flow system.
