    "abstract": "We present a toolbox for cold atom manipulation with time-dependent magnetic\nfields generated by an atom chip. Wire layouts, detailed experimental\nprocedures and results are presented for the following experiments: Use of a\nmagnetic conveyor belt for positioning of cold atoms and Bose-Einstein\ncondensates with a resolution of two nanometers; splitting of thermal clouds\nand BECs in adjustable magnetic double well potentials; controlled splitting of\na cold reservoir. The devices that enable these manipulations can be combined\nwith each other. We demonstrate this by combining reservoir splitter and\nconveyor belt to obtain a cold atom dispenser. We discuss the importance of\nthese devices for quantum information processing, atom interferometry and\nJosephson junction physics on the chip. For all devices, absorption-image video\nsequences are provided to demonstrate their time-dependent behaviour.",
