US Patent:

49838113, Jan 8, 1991

Filed:

Jun 16, 1989

Appl. No.:

7/367863

Inventors:

Rick L. Oppor - Hanover Park IL
Timothy L. Braun - Lombard IL

Assignee:

Appliance Control Technology, Inc. - Addison IL

International Classification:

H05B 102

US Classification:

219497

Abstract:

An auxiliary control system for an oven or similar device that is separate from the primary control circuitry and operates independently when the condition occurs that could be hazardous or unsafe. The control acts to prevent the temperature of a known point to rise above a predetermined set point, or points, and the primary circuitry failed to take corrective action.

Timothy Braun - Roselle IL

International Classification:

B41J 2085

US Classification:

347 76

Abstract:

Printing distortions caused by ink stream/charge tunnel misalignment, charge tunnel mis-dimensioning or a variation in drop spacing or changes in ink resistivity are corrected by measuring the actual induction co-efficients for a particular printer. For this purpose, charge sensors located along the ink stream or adjacent the ink catcher detect induced charges from which the induction co-efficients are calculated by a programmable controller. These co-efficients are used to adjust the charge tunnel voltages to reduce or eliminate printing distortion.
