Filed:

Feb 14, 2003

Appl. No.:

10/366978

Inventors:

Stanley W. Seevers - Perrysburg OH, US
Guy R. Hughes - Lawrenceburg IN, US
Frank A. Robinson - Sylvania Township OH, US

Assignee:

Master Chemical Corporation - Perrysburg OH

International Classification:

G01N033/00

US Classification:

73 6159, 73 6142, 73 5305, 73 6456, 73 6141

Abstract:

An automatic system for monitoring/controlling a variable of a machine or metalworking fluid system also achieves cleaning and optionally, a calibration check of the sensor of the variable. The system includes one or more sensors for variables such as pH, fluid concentration, conductivity, temperature and the like, a supply of a cleaning agent and associated valves and conduits for connecting the automatic system to a fluid to be measured. A cleaning cycle can be scheduled as necessary to clean and/or check calibration of the sensors and ensure accurate measurement of sensed variables. If desired, the data regarding the sensed variables may be utilized to perform corrective action in real time.

Nov 3, 2008

Appl. No.:

12/263916

Inventors:

Kenneth K. Buchanan - Renton WA, US
Paul W. Norby - Tacoma WA, US
Frank H. Robinson - Des Moines WA, US
Kevin J. Raiche - Burien WA, US
Jeffrey D. Morgan - Auburn WA, US

International Classification:

B61D 17/02

US Classification:

52 84, 527414, 5274519

Abstract:

The different illustrative embodiments provide a method and apparatus for installing an edge seal. In one illustrative example, a pre-cured edge seal is placed on an edge of a composite structure with a sealant to form a placed pre-cured edge seal. The placed pre-cured edge seal is then cured on the composite structure.In another illustrative embodiment, an edge of a structure is prepared with solvent, and a brush coat of sealant is applied to the top and the edge of the structure. A fillet is applied to the base of the edge of the structure. A pre-cured edge seal is applied to the edge of the structure, and the edge is cured.

Appl. No.:

5/876467

Inventors:

Thomas E. Grime - Temperance MI
Frank A. Robinson - Toledo OH

Assignee:

Champion Spark Plug Company - Toledo OH

International Classification:

H05B 360
B65D 5502
E05B 1100

US Classification:

219295

Abstract:

A safety device for an electrode-type steam vaporizer having an electrode assembly enclosed in a protective housing allows access to the electrodes for cleaning or adjustment only when a key, preferably the electric plug for the vaporizer, is inserted through an opening in the protective housing to release an interlock mechanism normally precluding removal of the protective housing from the electrode assembly. When the protective housing is removed, the key is automatically locked in the opening in the protective housing by a spring-biased lock pin and cannot be removed until the electrode assembly is again repositioned in the housing with the electrode assembly and housing properly assembled relative to each other. The safety device can be used in other electrical appliances, such as a toaster, that have electrical elements enclosed in a protective housing.

Appl. No.:

7/687977

Inventors:

Frank A. Robinson - Toledo OH
Albert S. Orr - Indianapolis IN
Marvin D. Burns - Millbury OH
Alan H. Fritz - Toledo OH

Assignee:

Ransburg Corporation - Indianapolis IN

International Classification:

B05B 128

US Classification:

239296

Abstract:

A replaceable baffle for dropping high pressure air to low pressure air for atomization and for pattern shaping in a high volume low pressure (HVLP) air paint spray gun. The baffle has a first plurality of orifices for distributing and dropping the air pressure to a low pressure for atomization and has orifices arranged in two stages for dropping the air pressure to a low pressure for pattern shaping. The baffle may be replaced with a baffle having different sized orifices to permit use of different air cap and/or fluid tip designs on the spray gun when applying paints having different flow properties.
