Method And Device For Evaluating And/Or Adjusting The Cleaning Performance Of A Cleaning Liquid

View page
US Patent:
6694804, Feb 24, 2004
Filed:
Sep 23, 2002
Appl. No.:
10/252281
Inventors:
Robert R. Roelofs - Allen Park MI
Assignee:
PPG Industries Ohio, Inc. - Cleveland OH
International Classification:
G01N 3700
US Classification:
73 6011, 73 5301, 73 5417
Abstract:
A method and device are provided for measuring and/or adjusting the cleaning performance of a cleaning liquid. One method of the invention includes determining a control value (i. e. , the number of drops of the cleaning liquid to provide a selected volume) indicative of when the cleaning performance of the cleaning liquid is at or approaching an unacceptable level. At least one substrate can be contacted with the cleaning liquid and a drop number for the cleaning liquid (i. e. , the number of drops of the cleaning liquid to provide the selected volume) again measured. At least one cleaning agent, such as at least one surfactant, can be added to the cleaning liquid when the measured drop number is at or near the control value. In one embodiment, the cleaning agent can be added until the measured drop number is at or near a baseline drop number for the cleaning liquid (i. e. , the number of drops of the cleaning liquid when cleaning performance is acceptable).

10/767913
Inventors:
Robert R. Roelofs - Allen Park MI, US
Hans F. Letzring - Pleasant Ridge MI, US
Assignee:
PPG Industries Ohio, Inc. - Cleveland OH
International Classification:
B05D 1/38
US Classification:
427202, 427195, 427203
Abstract:
This invention is directed to an improved method of coating a substrate. The improvement includes applying to the substrate a rinse composition which contains one or more surface energy-modifying compounds. The invention is further directed to an improved method of producing weldable parts and the parts prepared by this method. The invention is especially useful for automotive parts using weldable pre-painted metal substrates to which are applied essentially zero VOC powder coatings.

Bimetal Laminate Structure And Method Of Making The Same

View page
US Patent:
20090269562, Oct 29, 2009
Filed:
Apr 25, 2008
Appl. No.:
12/109531
Inventors:
Robert Roelofs - Allen Park MI, US
Dan Bullard - Valparaiso IN, US
Mike Bilos - Chicago IL, US
Bryan Tullis - Royal Oak MI, US
Assignee:
MATERIAL SCIENCES CORPORATION - Elk Grove Village IL
International Classification:
B32B 7/12
B65C 9/25
US Classification:
428215, 428213, 156322
Abstract:
The present invention provides a bimetal laminate structure and improved method for manufacturing the same. The method includes: applying a layer of adhesive to a metallic substrate; and laminating a decorative metallic sheet to the metallic substrate in such a manner that substantially all surface defects and all read through appearance along an outer surface of the decorative metallic sheet are eliminated. The resultant bimetal laminate includes a decorative metallic layer consisting of a first metallic material, and a metallic substrate consisting of a second metallic material that is different from the first metallic material. The metal substrate has a thickness that is greater than the thickness of the decorative metallic layer. An adhesive layer is disposed between, and spans substantially the entirety of the decorative metallic layer and metallic substrate to rigidly attach the same.

US Patent:
59935626, Nov 30, 1999
Filed:
May 18, 1998
Appl. No.:
9/080482
Inventors:
Robert R. Roelofs - Allen Park MI
Jonathan N. Warren - Dearborn MI
Robert N. Deneau - Lake Orion MI
Assignee:
PPG Industries Ohio, Inc. - Cleveland OH
International Classification:
B08B 700
B08B 900
US Classification:
134 7
Abstract:
A method of cleaning interior surfaces of fluid delivery systems including (a) passing through the system an abrasive cleaner composition including at least one liquid carrier containing solubilizable abrasive particles, at least some of which are in non-solubilized form, effective to abrade the material to be removed from the interior surfaces, and (b) rinsing the system with at least one fluid effective to (i) displace the carrier and (ii) remove the abrasive particles, at least partially by such chemical means as dissolution or decomposition or neutralization. Optionally, the method can include a first step of contacting the inside surfaces of the fluid delivery system with a pretreatment fluid capable of softening or loosening the material that is to be cleaned from the internal surfaces of the delivery system for a time sufficient to soften or loosen unwanted material.
