Abstract: A conducting loop has thick cross section and is powered by a single voltage source capable of producing extremely high currents. Anti-parallel segments of the loop are brought in close proximity to each other and the unpaired segments in this loop are shaped to collectively form a homogenous B0 field. Voltage sources shunt current from one point of the thick loop to another such that the resulting redistribution of current within the thick loop allows it to simultaneously establish required gradient fields and/or shimming fields in addition to its Bo field.

Abstract: A dispenser with increased stability includes a pillar tube extending from the stem-spring chamber assembly at the top of the fluid reservoir to the bottom of the fluid reservoir. The pillar tube transmits the force from the hand of the user used to dispense fluid to a pressure sensitive attachment device on the bottom of the fluid reservoir.
