Abstract: A tray assembly is provided for use with a carrier in a product sortation system. The tray assembly includes a platform to receive parcels loaded onto the carrier. A pair of movable edge members are disposed at opposite sides of the platform. Each edge member is integrated with a combination including a pair of pivotable support arms and a spring element intermediate of the support arms. Each support arm supports its edge member at one end and is pivotally mounted at another end to a tray framework. The spring element is fixedly mounted at one end to the tray framework and is connected at another end to its edge member in a biasing relationship. In response to an applied load resulting from a parcel bearing down on the edge member, the support arms pivot downward in a manner sufficient to allow the parcel to reach and then rest on the tray platform. At the same time as the support arms pivot, the spring element deflects.

Abstract: A mechanical linkage system is provided to facilitate controlled tilting of a tray mounted on a carrier in a product sortation system. A pair of rotatable tilt plates are disposed between a pair of base plates and support the tray. A rotatable pivot bar is disposed between the base plates. A pair of linkage mechanisms are configured to tilt the tray in opposite directions. Each linkage mechanism includes a link pivotally connected at one end to the pivot bar, a pivot arm, and a cam follower. The pivot arm has a pivot joint connected to another end of the link, a cam joint where the cam follower is located, and a rotary joint where the pivot arm is rotatably connected to one of the base plates. The cam follower is situated in a track formed in one of the tilt plates. During operation, a pivoting of the pivot bar is transformed by the linkage mechanism into a rotation of the tilt plate, which is induced by the cam follower traveling through the track as the pivot arm rotates.

Abstract: The base plate of a robotic or manually propelled tank or pool cleaning apparatus includes a transverse conduit positioned on the interior surface of the base plate and is in fluid communication with a source of pressurized water that is also located within the pool cleaner's housing, which pressurized water is discharged from the bottom or lower portion of the transverse conduit through a plurality of openings that extend along a line that is transverse to the longitudinal axis of the pool cleaner's direction of travel, to produce downwardly-directed water jets that are discharged through and below the base plate towards the surface of the pool or tank over which the pool cleaning apparatus is moving to dislodge and suspend dirt and debris that is then drawn into and retained by the pool cleaner's filter.

Abstract: An automated self-propelled robotic pool cleaner having a housing and drive means for moving the pool cleaner over at least the bottom wall of a pool, is provided with an integral on-board electrochemical chlorine generator for producing chlorine from a chlorine compound, e.g., sodium chloride, that is dissolved in the pool water, a source of electrical power operatively connected to the electrochemical chlorine generator, control means for initiating and terminating the operation of the chlorine generator, and an outlet for discharging water containing chlorine ions produced by the electrochemical generator to thereby distribute the chlorine into the water proximate the exterior of the pool cleaner housing as the pool cleaner follows a programmed operational mode across the bottom and/or side walls of the pool. The operation of the chlorine generator is in response to a manually operated switch and/or signals transmitted directly or indirectly to the control means.
