US Patent:

56784848, Oct 21, 1997

Filed:

May 4, 1995

Appl. No.:

8/435006

Inventors:

Ronald Callan - Lemont IL
Michael Gregory - Winfield IL
Steven Drensky - Waukegan IL

Assignee:

Baldwin Web Controls - Lombard IL

International Classification:

B41F 1302

US Classification:

101226

Abstract:

A system and method for preventing a broken printing web from wrapping about or otherwise fouling the blanket cylinders of printing press units. The system and method includes a web tensioning device located downstream of the printing press units for maintaining tension upon a broken web and pulling the web from the printing press units. The device includes a plurality of web disturbance detectors for detecting a wave, ripple or other disturbance indicative of a web break. A pair of anti-wrap rollers located above and below the web are engaged upon detection of a web break to engage the web between them to exert tension onto the web and pull it from the printing units. The anti-wrap rollers are rotated at a surface speed nominally greater than the surface speed of the printing rolls. The anti-wrap rollers include a plurality of opposed peak and valley portions which enable them to interlock and grip the web along a line of contact. The system and method also includes a flow bar system to reduce false detections of a web break.

Inventors:

Ronald Callan - Lemont IL
Michael Gregory - Winfield IL
Tat Luk - Aurora IL
Gifford Neill - Hanover Park IL

Assignee:

Baldwin Web Controls - Lombard IL

International Classification:

G01N 2910

US Classification:

73628

Abstract:

An apparatus for detecting breakage of a web of material traversing a machine for feeding the web, and a method for the same. The apparatus includes a housing for mounting three transducers, a first transducer adapted to periodically emit a burst of energy for a period of time, the burst of energy being reflected off an object and producing an echo signal. A second transducer adjacent to the first transducer receives a portion of the echo signal, and a third transducer also adjacent to the first transducer receives another portion of the echo signal. The strongest portion of the echo signal is used to detect whether the web is broken.

Appl. No.:

Inventors:

Michael A. Gregory - Chicago IL

International Classification:

F16L 500

US Classification:

137362

Abstract:

An expansible, resilient receptacle positionable about a standpipe installed for the relief of subsurface water pressure occasioned specifically by sewer backup. The receptacle surrounds the standpipe and communicates with the inner portion thereof through strategically located openings in the walls of the standpipe. The water introduced to the receptacle bulges its walls and urges a watertight engagement between the walls and floor about the base of the standpipe. The seal contains any water leaking upwardly around the base of the standpipe and prevents the floor from failing. In the event the excessive subsurface water pressure is encountered, the water is permitted to escape into the room to avoid possible rupture of the floor surface. The water is releaseable from the receptacle when the subsurface pressure diminishes.
