Patent number: 7740130Abstract: A digital processor for use in a conveyor belt rip detector, which provides excitation signals at a selected frequency to inverted and noninverted sensor loops on a conveyor belt and then, detects corresponding received signals from the sensor loops. The digital processor then performs FFTs on the corresponding received signals to provide respective received signal frequency spectrums. Next magnitude and phase values of the selected frequency in the respective received signal frequency spectrums are used to determine a qualitative state of the sensor loops. The selected frequency has a lowest detected ambient noise level, and the magnitude value is a normalized magnitude value.Type: GrantFiled: May 31, 2006Date of Patent: June 22, 2010Assignee: Veyance Technologies, Inc.Inventors: Jack Bruce Wallace, John James Gartland, Richard Herman Blausey, Edward Louis Kerekes, Jr.

Patent number: 7740128Abstract: A self-synchronizing system and method for conveyor belt sensor operation is disclosed based on the address of an RFID tag in the belt and the location of that tag in the system memory. A moving conveyor belt system has a plurality of sensors spaced along the belt and a sensor reader for detecting and identifying the presence of a sensor passing by the sensor reader. The belt further includes a plurality of identification tags spaced along the belt and a tag reader for detecting and identifying the presence of a tag passing by the tag reader. Associated time and distance target values are acquired from a calibration table for a next sensor (S1) based upon a detected and identified functional tag. Time and distance counters are initiated. The conveyor belt may be stopped in the event that the next sensor (S1) is not detected before the time and distance target values are exceeded.Type: GrantFiled: November 8, 2005Date of Patent: June 22, 2010Assignee: Veyance Technologies, Inc.Inventors: Jack Bruce Wallace, John James Gartland

Publication number: 20100055363Abstract: Floating hose is normally comprised of a carcass that is covered with a layer of foam to provide buoyancy. The foam can be deformed and compressed by being repeatedly reeled onto a drum under conditions of high axial forces (reeling forces plus hose weight). The propensity for the foam layer to become compressed is aggravated in typical conditions where the hose is stored on a reel for extended periods and is on the reel more than it is in the water. In any case, compression damage causes the hose to lose buoyancy which can ultimately result in the hose sinking under conditions of normal use. It would accordingly be desirable to develop a floating hose that minimized the permanent damage caused by the foam layer being compressed to high levels over and over again. The floating hose of this invention is resistant to damage that can be caused by axial forces, such as those encountered while being collected on a reel.Type: ApplicationFiled: September 4, 2009Publication date: March 4, 2010Applicant: VEYANCE TECHNOLOGIES, INC.Inventors: Ronald M.
