Abstract: A sack includes a flexible sack body and a mouth that includes two separable lips that form a mouth opening when the lips are separated from one another, and that close the opening when the lips are adjacent to one another. Closing structure is configured to enable a separating force that is applied to the lips to separate the lips from one another to form the mouth opening, and to bring the lips adjacent to one another to close the mouth opening in the absence of the applied separating force.

Abstract: An order fulfillment system includes a plurality of stock locations for storing items, and movable collection containers, each configured to hold one or more of the items. A network of tracks along which each of the collection containers is configured to move in a single direction includes junctions where at least two of the tracks intersect, each collection container being controllable at a junction to continue travelling along one of the tracks. The network of tracks is configured to enable the collection containers to move to the stock locations. A controller is configured to receive a list of ordered items, to determine a selected stock location at which each ordered item is stored, to calculate a route along the network of tracks to bring a collection container to each selected stock location, and to control movement of that collection container along the calculated route to the selected stock locations.

Abstract: A sorting system includes one or a plurality of transporter units, at least one loading station for loading a parcel onto transporter units, a plurality of destination stations, and a network of paths, each path including at least one track, the network including a plurality of junctions where at least two of the paths intersect. Each transporter unit is controllable to travel along the paths of the network of paths and to continue travelling along one of the at least two paths at a junction. A controller is configured to calculate a route within the network of paths between a loading station and a selected destination station, and to control the transporter unit to travel along the calculated route.

Abstract: The present invention presents a non-destructive method and means of obtaining either the inner portion or the outer contour of a two-dimensional or three-dimensional model of the outer contours of a gemstone.

Abstract: Communication system for a rotating turret having a plurality of electronic components, comprises: a first aggregated communication link connecting between the turret and external electronics, and a first internal communication switch located within the turret for connecting each of the plurality of electronic devices to a channel of the aggregated communication link.
