US Patent:

54430089, Aug 22, 1995

Filed:

Oct 21, 1994

Appl. No.:

8/327095

Inventors:

Mark Pavliny - Rolling Meadows IL
Edward Lewandowski - Hoffman Estates IL
William Lawrence - Addison IL
Michael Gregory - Wheaton IL
Guntis Ozers - Hinsdale IL

Assignee:

Baldwin Web Controls - Countryside IL

International Classification:

B41F 504

US Classification:

101484

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.

Filed:

Appl. No.:

8/188526

Inventors:

William P. Lawrence - Downers Grove IL
Apostolos C. Raptis - Downers Grove IL

Assignee:

The University of Chicago - Chicago IL

International Classification:

G01N 1100
G01N 2902

US Classification:

73 5441

Abstract:

An ultrasonic viscometer and method for measuring fluid viscosity are provided. Ultrasonic shear and longitudinal waves are generated and coupled to the fluid. Reflections from the generated ultrasonic shear and longitudinal waves are detected. Phase velocity of the fluid is determined responsive to the detected ultrasonic longitudinal waves reflections. Viscosity of the fluid is determined responsive to the detected ultrasonic shear waves reflections. Unique features of the ultrasonic viscometer include the use of a two-interface fluid and air transducer wedge to measure relative signal change and to enable self calibration and the use of a ratio of reflection coefficients for two different frequencies to compensate for environmental changes, such as temperature.

Assignee:

The University of Chicago - Chicago IL

International Classification:

G01L 504
G01N 2900

US Classification:

73159

Abstract:

An ultrasonic method and system are provided for monitoring a fabric to identify a defect. A plurality of ultrasonic transmitters generate ultrasonic waves relative to the fabric. An ultrasonic receiver means responsive to the generated ultrasonic waves from the transmitters receives ultrasonic waves coupled through the fabric and generates a signal. An integrated peak value of the generated signal is applied to a digital signal processor and is digitized. The digitized signal is processed to identify a defect in the fabric. The digitized signal processing includes a median value filtering step to filter out high frequency noise. Then a mean value and standard deviation of the median value filtered signal is calculated. The calculated mean value and standard deviation are compared with predetermined threshold values to identify a defect in the fabric.

Abstract:

Systems, methods, and apparatus for a data bus-in-a-box (BiB) are disclosed. The system involves an electrical box, and at least one optical connector located on the box. The system further involves at least one mother board housed inside of the box, and comprising a transmit side comprising at least one transmit optical media converter (OMC) tile, and a receive side comprising at least one receive OMC tile. Also, the system involves first receive optical fibers that are each connected from at least one receive OMC tile to a receive coupler; and a second receive optical fiber connected from the receive coupler to one of the optical connectors. Further, the system involves first transmit optical fibers that are each connected from at least one transmit OMC tile to a transmit coupler; and a second transmit optical fiber connected from the transmit coupler to at least one of the optical connectors.
