Abstract: A feed mechanism for a food slicing machine. The feed mechanism is capable of dual configurations: gripper mode and continuous feed mode. The apparatus has dual conveyors that can feed food products continuously, and a gripper mechanism that can feed food products reciprocatingly. Before engaging the continuous mode, the gripper mechanism is driven to an end of the machine and then a drive belt, which a jaw clamps during the gripper mode, is released. The dual, opposing conveyors then feed the food product that rolls to them by gravity over a moveable roller frame extending beneath the gripper mechanism. During gripper mode, the upper conveyor can be removed or raised out of the way, and the moveable roller frame is positioned just beneath the gripper. The gripper jaw clamps the drive belt and the gripper is driven in a reciprocal manner over the lower conveyor.

Abstract: The invention provides an incubation vessel supporting apparatus, including a moveable support and a plurality of incubation vessel mountings carried by the support and moveable independently relative to the support such that, in use, each of the plurality of vessel mountings is simultaneously independently moveable so that each vessel mounted by the mountings is capable of movement to achieve substantially the same temperature/time integral. Such vessel supports can be used in, for example, an automated assay apparatus.
