| 20090113985 | FLUID FLOW MEASURING AND PROPORTIONAL FLUID FLOW CONTROL DEVICE - Embodiments disclosed herein provide restrictive-flow flow measurement devices, valve improvements and signal control devices and processes that control the flow of liquids, including control processes for single-liquid calibration. In some embodiments, a fluid flow device can be calibrated using a single standard calibration fluid. The fluid flow of a first fluid through a flow meter is measured by calculating a first pressure difference between pressures sensed by two pressure sensors of the flow meter. The fluid flow of a second fluid through the flow meter is measured by calculating a second pressure difference between pressures sensed by the same two pressure sensors. A calibration coefficient is determined based upon the relationship between the flow rate, the fluid density and the calculated pressure difference for the first and second fluids. A relationship between the calibration coefficient and the kinematic viscosity of each fluid is then determined and stored. | 05-07-2009 |

| 20130041625 | Advanced Statistical Detection of Emerging Trends - Advanced statistical detection of emerging trends in a process is disclosed, based on a Repeated Weighted Geometric Cumulative Sum analysis, which may be combined with time window-based estimation of proportions and related thresholds. Threshold derivation and significance computation is based on parallel simulation runs with power-exponential tail approximations. A battery of tests using the statistical theory of sequential analysis and change-point theory in combination with targets is used to evaluate non-conforming conditions in a process. Trends in fall-out rates are detected based on non-time-to-failure data that corresponds to counts of failures in consecutive time periods, with possibility of delayed input. | 02-14-2013 |

| 20100193329 | ACCUMULATION-AND-RELEASE CONVEYOR - An accumulation-and-release conveyor using a roller belt with rollers arranged to rotate in the direction of belt travel. The rollers extend through the thickness of the belt. A movable stop is positioned along the carryway just downstream of a bearing surface that is movable into and out of contact with the rollers. When the bearing surface is out of contact with the rollers, they are freely rotatable; when the bearing surface contacts the rollers, they roll on the bearing surface to propel articles in the direction of belt travel. The stop is selectively moved between a blocking position preventing articles from passing and accumulating them with low back line pressure on the freely rotatable rollers and a release position allowing articles to pass to the accumulation zone where they are propelled forward and separated from each other by the rotation of the rollers rolling on the bearing surface. | 08-05-2010 |
| 20100270122 | CASE TURNER FOR A ROLLER CONVEYOR - A case turner comprising a powered roller conveyor with a bump turn and a tapered roller just downstream of the bump turn to assist in turning cases completely 90°. The larger diameter of the tapered roller is on the opposite side of the conveyor from the bump turn. | 10-28-2010 |
| 20110017575 | Low-Pressure Accumulation System - A low-pressure accumulation system and a conveyor belt in an accumulation conveyor for the use with the system. The belt, which is flanked on opposite sides by lines of gravity rollers, has a longitudinal lane of article-supporting belt rollers arranged in groups along the length of the conveyor belt. The groups are spaced apart from each at regular intervals. Trays sit atop the gravity rollers until they are lifted slightly higher by one of the slightly elevated groups of article-supporting belt rollers, which engage the bottom of the tray and convey it along toward a discharge end. Retractable stops selectively block the trays from advancing on the accumulation conveyor. The freely rotatable article-supporting belt rollers roll along the bottoms of any blocked and accumulated trays and provide low back pressure. The belt may also include low-friction rollers that ride on bearing surfaces below the belt to help lower friction between the belt and the conveyor structure while the belt is running. | 01-27-2011 |
| 20110215036 | PACKAGE-CULLING CONVEYOR SYSTEM AND METHOD - A package-culling conveyor system and a method for culling flat packages from a bulk flow of flat and non-flat packages. The conveyor system includes a tilted conveyor belt that conveys flat packages along its length while non-flat packages tumble off its lower side edge to initially cull flat packages from a bulk flow of packages. Retention means, such as a high-friction outer conveying surface or a raised barrier along the length of the outer conveying surface of the tilted conveyor belt, holds flat packages on the tilted conveyor belt. The initially separated packages are more fully culled in a conveyor comprising a roller conveyor belt with package-supporting belt rollers rotated in a direction to push packages sidewise toward a culling element that extends along the length of the roller conveyor belt. Examples of culling elements include powered rollers and vertical walls forming side guards. The powered roller lifts the contact side of non-flat packages to free flat packages underneath. The belt rollers push the flat packages under the culling elements and off the side of the roller belt. The culling elements block the non-flat packages from exiting laterally off the side of the roller belt so that they are conveyed off the exit end of the roller belt separate from the flat packages. | 09-08-2011 |
| 20130272832 | WORKSTATION FOR UNLOADING A PALLET - A workstation to aid in the manual unloading of a pallet. The workstation comprises a work area bounded on tows ides by a pallet load platform, a takeaway conveyor, and two parallel conveyors. An operator standing in the work area removes pallet elements from the top layer of the pallet load and places them on one or the other parallel conveyors, which convey them to the takeaway conveyor. The parallel conveyors, which may be tilted gravity conveyors or powered conveyors, are hinged so that they can be raised to an open position allowing operator to enter or exit the work area. The pallet layer may be supported on a tilted scissor lift. | 10-17-2013 |
| 20140008274 | CONVEYOR SYSTEMS AND METHODS - A conveyor system and methods for conveying and unstacking flat and non-flat packages. The conveyor system includes an inclined conveyor belt delivering packages to a tilted conveyor belt that conveys flat packages along its length while non-flat packages tumble off its lower side edge to initially cull flat packages from a bulk flow of packages. Retention means, such as a high-friction outer conveying surface or a raised barrier along the length of the outer conveying surface of the tilted conveyor belt, holds flat packages on the tilted conveyor belt. The inclined conveyor belt has stop elements spaced apart along the belt's length and is advanced in stop-and-go fashion to help unstack piggy-backed packages as they are conveyed up the incline. The initially separated packages are more fully culled in a conveyor comprising a roller conveyor belt with package-supporting belt rollers rotated in a direction to push packages sidewise toward a culling element that extends along the length of the roller conveyor belt. | 01-09-2014 |
