Patent ID: 7800369

Claim:
An NMR apparatus comprising an NMR probe with an RF coil for stimulating a nuclear magnetic resonance in a sample and detecting response, a first plurality of adjustable circuit components tuning and matching the RF coil, each said adjustable circuit component mechanically coupled to a corresponding driven shaft for enabling adjustment of the corresponding adjustable circuit component, a first plurality of driven gears, at least one driven gear of said plurality connected to the corresponding driven shaft of each adjustable component, said driven gear being capable of axial displacement along the direction of said driven shaft and azimuthally fixed to rotation of said driven shaft; a motor for rotating at least one driving gear capable of engaging with any one driven gear of said plurality; and a first plurality of linear actuators, each linear actuator mechanically coupled to a corresponding platen, said platen disposed to urge, upon actuation of said linear actuator, a corresponding driven gear along said corresponding driven shaft to a state of engagement with said driving gear, whereby said adjustment of the corresponding adjustable circuit component is made.
