Patent number: 6413579Abstract: The invention is a method of making a coated glass substrate having a low haze. A soda-lime glass substrate having at least one surface upon which a coating may be deposited is provided. The glass substrate is heated and maintained at a temperature sufficient to volatilize salts that may be formed during the depositing of a first coating on the glass substrate. A first gaseous precursor mixture including a halogen containing precursor, a metal precursor, an oxidizing agent, and an inert to carrier gas is directed toward and along the surface to be coated and reacting the mixture at or near the surface of the glass substrate to form a first coating containing a metal oxide coating. The glass substrate is cooled to a temperature to reduce crystalline growth in a second coating to be applied over the first coating.Type: GrantFiled: January 27, 2000Date of Patent: July 2, 2002Assignee: Libbey-Owens-Ford Co.Inventors: Douglas Nelson, Steven Phillips

Patent number: 6268612Abstract: An autobalance control circuit for use in a moisture sensor which senses moisture on the surface of a transparent material. The moisture sensor includes detectors for receiving emitter signals which are influenced by moisture on the transparent material. The moisture sensor further includes a pre-demodulation circuit for attenuating unwanted signal components in the detector output signal while amplifying the useful signal components for further processing by a microprocessor. An autobalance circuit is provided for receiving the pre-demodulation circuit signal and providing an autobalance signal to the pre-demodulation circuit input. The autobalance signal at least partially cancels the detector output signal to prevent saturation of the pre-demodulation amplifier when undesirable detector output signal amplitudes are encountered.Type: GrantFiled: June 12, 2000Date of Patent: July 31, 2001Assignee: Libbey-Owens-Ford Co.Inventor: Rein S.

Patent number: 6238738Abstract: A chemical vapor deposition process for laying down a tin or titanium oxide coating on a glass substrate through the use of an organic oxygen-containing compound and the corresponding metal tetrachloride. The organic oxygen compound is preferably an ester having an alkyl group with a &bgr; hydrogen in order to obtain a high deposition rate. The resulting article has a tin or titanium oxide coating which can be of substantial thickness because of the high deposition rates attainable with the novel process, and, in the case of titanium oxide coating possesses a desirable refractive index greater than 2.4.
