20080282457 | CANISTER FLUSH VALVE - A canister type flush valve has an upright cup-shaped hollow float working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area. The seal is backed by a slotted flange located just above the retaining groove. | 11-20-2008 |

20130035783 | MOVING STOP STATION FOR ROBOTIC ASSEMBLY - A moving stop station includes a vehicle carrier configured to move a vehicle along an assembly line, an assembly platform disposed adjacent to the assembly line, and a synchronizer in communication with the vehicle carrier and the assembly platform. The synchronizer is configured to synchronize the motion of the assembly platform with the motion of the vehicle carrier as the vehicle carrier moves along a length of the assembly line, and includes a sensor, processor, and actuator. The sensor is configured to sense the position of the vehicle carrier and to generate a position signal corresponding to the sensed position. The processor is configured to receive the position signal and selectively provide a synchronization signal in response, and the actuator is configured to receive the synchronization signal and synchronize the motion of the vehicle carrier and the motion of the assembly platform in response. | 02-07-2013 |

20130158709 | ROBOT CONTROL DURING AN E-STOP EVENT - A system for a work cell having a carrier that moves a product along an assembly line includes an assembly robot, sensor, and controller. An arm of the robot moves on the platform adjacent to the carrier. The sensor measures a changing position of the carrier and encodes the changing position as a position signal. The controller receives the position signal and calculates a lag value of the robot with respect to the carrier using the position signal. The controller detects a requested e-stop of the carrier when the arm and product are in mutual contact, and selectively transmits a speed signal to the robot to cause a calibrated deceleration of the platform before executing the e-stop event. This occurs only when the calculated tracking position lag value is above a calibrated threshold. A method is also disclosed for using the above system in the work cell. | 06-20-2013 |
