| 20110005904 | AUTOMATIC BELT TRACKING SYSTEM - In an aspect of the present invention, a system and method are provided that detect belt mis-tracking and in response, automatically adjusts. In some implementations, the system and method are implemented in conjunction with a weigh feeder or weigh belt. In other implementations, the system and method are implemented in conjunction with other devices that convey material via one or more belts. The system and method can be implemented by providing one or more sensors that detect belt mis-tracking, a motor for adjusting a belt pulley and one or more controllers that operate the motor in response to signals from the one or more sensors. | 01-13-2011 |
| 20100127194 | CINCH VALVE - A cinch valve includes an upper plate having a first aperture; an orbital plate rotatable relative to the upper plate and having a second aperture substantially aligned with the first aperture; an actuator coupled to the orbital plate arranged to rotate the orbital plate between a first position and a second position; and a plurality of cables each having a flexible portion and each having a first end and a second end, wherein each first end is coupled to the upper plate and each second end is coupled to the orbital plate. Rotation of the orbital plate from the first position to the second position causes the plurality of cables to converge and form a woven closure in approximately the center of the second aperture. | 05-27-2010 |

The system and method can be implemented by providing one or more sensors that detect belt mis-tracking, a motor for adjusting a belt pulley and one or more controllers that operate the motor in response to signals from the one or more sensors. | 04-09-2009 |
| 20090050654 | Metering Mechanism For Strand-Type Bulk Solid Materials - A system and method are disclosed that provide a specific volumetric output (e.g., product feed and discharge) of a material. In some implementations, these systems and methods are particularly suited for use with strand-type materials, namely, materials having difficult handling characteristics. For some implementations, a specific pile depth and width of a material is created on a moving belt to provide a specific volumetric output based on the speed of the belt. One or more leveling drums can be used to make the pile depth consistent. Moreover, a weighing system can be provided that is used in combination with the metering mechanism and other components (e.g., a control system) to create a “weight-loss” type weigh feeder. | 02-26-2009 |
