Abstract: Methods, systems, and apparatus for a conveyor assembly. The conveyor assembly includes a conveyor, at least one stationary track positioned parallel to the conveyor, a process dolly configured to operatively couple to the at least one stationary track, and a syncing apparatus configured to couple to the process dolly and operatively couple to the conveyor. The syncing apparatus is configured to lock the process dolly in place along the conveyor such that the process dolly moves together with the conveyor with respect to the at least one stationary track.

Abstract: Apparatuses, systems, and methods for receiving a part from another system. An apparatus includes a platform configured to receive a first part and a second part to be unloaded from another apparatus. The apparatus further includes a first guide member and a second guide member. The first guide member and the second guide member are configured to engage with, respectively, a first engaging member and a second engaging member on another apparatus and enable the first part and the second part to be unloaded. The first guide member and the second guide member may be configured to contact, respectively, the first engaging member and the second engaging member to actuate a first gate member connected to the first engaging member and a second gate member connected to the second engaging member to move to open positions to enable the first part and the second part to be released.

Abstract: Apparatuses, systems, and methods for delivering a part to another system. An apparatus includes a platform. The platform includes a plurality of holding stations configured to hold a plurality of parts to be delivered to another system. The plurality of holding stations include at least a first holding station and a second holding station. The apparatus further includes a first gate member and a second gate member. The first gate member is coupled to the first holding station and a first engaging member and is configured to move to an open position when the first engaging member is engaged with a first guide member coupled to another apparatus. The second gate member is coupled to the second holding station and a second engaging member and is configured to move to an open position when the second engaging member is engaged with a second guide member coupled to another apparatus.

Abstract: A delivery dolly includes a carousel that is rotatably mounted on a support column. The carousel includes a recess on an underside of the carousel. A locking mechanism is biased toward a locked position. The locking mechanism includes a locking wheel on which the carousel rotates until the carousel reaches a preselected angular position. The recess aligns with the locking wheel at the preselected angular position and, due to a bias force, the locking wheel extends into the recess to inhibit rotation of the carousel until the carousel is spun manually, forcing the carousel to rotate and the locking wheel to retract until the locking wheel encounters the recess again.

Abstract: Impure aromatic carboxylic acids such as are obtained by liquid phase oxidation of feed materials comprising aromatic compounds with substituent groups oxidizable to carboxylic acid groups, or comprising aromatic carboxylic acid and one or more aromatic carbonyl impurities that form hydrogenated species more soluble in aqueous solvents or with less color or color-forming tendencies than the aromatic carbonyl impurity, are purified to an aromatic carboxylic acid product with lower levels of impurities by a process comprising contacting an aqueous solution comprising the impure aromatic carboxylic acid with hydrogen at elevated temperature and pressure with an attrition-resistance, acid stable catalyst composition comprising at least one hydrogenation catalyst metal and a support comprising relatively high surface area silicon carbide.
