Patent number: 4728353Abstract: Apparatus for pyrolytically forming a metal compound coating on an upper face of a hot glass substrate 1 in sheet or ribbon form comprises conveyor means 2 for conveying a the substrate along a path also indicated at 1 in a downstream direction 3, a roof structure 5 defining a coating chamber 6 opening downwardly onto the path 1 and means 7 for discharging coating precursor material into the chamber 6. Upstream of the coating chamber 6 there is an antechamber 25 which communicates with the coating chamber 6 via an entry slot 24 which is defined in part by the path of the substrate 1, and via which gas can be caused to flow into the coating chamber 6 so as to form (when the apparatus is in use) a blanket layer which covers the upper face of the substrate 1 along a first part of the length of the chamber 6. Means 26 is provided for controllably preheating the gas forming the blanket layer.Type: GrantFiled: November 14, 1986Date of Patent: March 1, 1988Assignee: GlaverbelInventors: Jean-Francois Thomas, Robert Terneu, Albert Van Cauter, Robert Van Laethem

Patent number: 4721632Abstract: This specification is directed to a method of improving the conductivity and lowering the emissivity of a doped tin oxide film on the surface of a soda lime silica glass sheet. The method includes the steps of heating the glass sheet to a temperature in a range from 1000.degree. F. to 1250.degree. F. Thereafter, a fluorine-containing compound is applied to a surface of the heated glass sheet to react therewith to form a film in which divalent oxygen atoms and hydroxyl ions on the surface of the glass sheet are replaced with monovalent fluorine atoms. In this manner, the surface of the glass sheet is brought closer to a state of electro-neutrality and the monovalent fluorine atoms form a more stable bond with soda and silica atoms of the surface of the glass sheet. Thereafter, a doped tin oxide film is applied to the film formed on the heated glass sheet to a thickness required to give the doped tin oxide film the desired conductivity and emissivity characteristics.Type: GrantFiled: August 25, 1986Date of Patent: January 26, 1988Assignee: Ford Motor CompanyInventor: Franklin I.

Patent number: 4719134Abstract: It is often required to solder an electrical connection to a component or a lead thereto via a contact pad. At present pads are commonly of materials that tend to oxidize during any subsequent heat processing of the device, and are then difficult to solder. It has now been discovered that certain alloys of copper containing manganese may be used to construct contact pads that are both solderable and remain so even when ovened in air at 200.degree. C., and the invention provides a method of constructing solderable contact pads upon a chosen substrate, in which method there is formed on the relevant area of the substrate a layer of such a manganese/copper alloy.Type: GrantFiled: October 1, 1986Date of Patent: January 12, 1988Assignee: The General Electric Company p.l.c.Inventor: Brian W.

Patent number: 4696837Abstract: In accordance with the invention, there is provided herein an improved chemical vapor deposition method for forming fluorine-doped tin oxide coatings using a liquid coating composition which includes a reactive organic fluorine dopant and an organotin compound. The method is carried out under a defined set of process conditions such that the coating produced has a minimum and constant sheet resistance which is substantially independent of deposition temperature.Type: GrantFiled: November 12, 1985Date of Patent: September 29, 1987Assignee: M&T Chemicals Inc.Inventor: Goerg H.
