Patent number: 5122394Abstract: A coating applicator is provided for depositing a film on a surface of glass or other substrates by chemical-vapor deposition. The applicator includes a pair of opposing coating nozzles for applying a vaporized coating-chemical reactant in a carrier gas to the surface at such a concentration and velocity that coating of the surface is achieved under substantially reaction-rate-controlled conditions. Each coating nozzle is positioned adjacent the surface with a small clearance therebetween, the clearance being open to the outside atmospehre. The opposing coating nozzles are directed toward each other at a selected angle with respect to the surface of the substrate. The angle and the clearance provide a condition where there is substantially no intermixing of coating vapors with the outside atmosphere.Type: GrantFiled: May 25, 1990Date of Patent: June 16, 1992Assignee: Atochem North America, Inc.Inventor: Georg H.

Patent number: 4583920Abstract: A positive displacement pump utilizes at least three driven displacer valves and a plurality of driving membranes and at least one pumping membrane to withdraw minute quantities of corrosive fluid from a drum and discharge same from a spray nozzle. The pump is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator comprising pneumatic logic circuitry. The driven displacer valves operate in a particular sequence to draw fluid into the pump body, advance same from pumping chamber to pumping chamber within the pump body, and then discharge same at a constant rate of discrete pulses through an outlet port. The pulse generator and logic circuitry provide the control pulses for operating the displacer valves at the proper times in the operational cycle. The delivery characteristics of the instant pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.Type: GrantFiled: December 28, 1983Date of Patent: April 22, 1986Assignee: M&T Chemicals Inc.Inventor: Georg H.
