A diagnostic imaging apparatus such as a magnetic resonance imaging (MRI) device includes a vacuum vessel (,) having a central helium reservoir (,) in which superconducting magnetic coil windings (,) are maintained at a superconducting temperature. The vacuum vessel defines a bore (,) within which a gradient tube assembly (,) and an RF coil (,) are received. The gradient tube assembly includes an integral tongue (,) extending from a patient end (,) thereof. A first constraint (,) retrains the gradient tube assembly in a &ldquo;push-pull&rdquo; arrangement in both directions along the z-axis. The constraint (,) is mounted to a patient-end of the vessel (,) at a lowermost (i.e., six o'clock) position. The constraint includes vibration isolators (,) interposed between the tongue and a saddle mount (,) to reduce vibration transmission from the gradient tube assembly to the vessel. A second constraint (,) and a third constraint (,) are positioned at the twelve-o'clock positions at the patient-end and service-end, respectively of the vessel. The constraints (,) restrain the gradient tube assembly in directions along the x and y-axes. Each constraint (,) includes at least one elastomeric plug (,) and means for expanding the plug along the x and/or y-axis to wedge the plug between the gradient tube assembly and a cylindrical housing member (,) defining the bore (,).

Method and apparatus for mounting gradient tube to diagnostic imaging device

A magnetic actuator for adjusting the zero and span settings of a transmitter used in industrial process control systems. The actuator has a single magnet in a housing. The actuator is removable from the transmitter. When the actuator is unactuated the magnet is in a null position wherein it does not actuate either the zero or span setting reed switches. The magnet can be moved to either a first position wherein it actuates the zero setting reed switch or a second position wherein it actuates the span setting reed switch. The actuator applies a torque in the proper direction to return the magnet to the null position when the torque applied to move the magnet to either the first or second position is removed.

A cover lock assembly for a process transmitter having threadably removable end caps and corrugated outer surfaces is provided for engaging the corrugated surfaces by way of a toothed cover lock which is removably affixed to the transmitter housing.
