A fully wetted ultrasound scanhead for medical applications is described in which the motor and the rotor are enclosed within a sealed housing filled with ultrasound coupling fluid. The invention includes a drive belt to drive the rotor from the motor, rather than a precision drive means. Speed adjustment means, including an encoder disk mounted on the rotor, provide feedback for an electronic speed controller. Accordingly, the speed of the motor can be adjusted as a direct consequence of the actual speed of the rotor.

Fully wetted mechanical ultrasound scanhead

A photographic processing apparatus for severing an advancing strip into successive segments and for mechanically segregating the segments in conjunction therewith includes a strip feed for advancing the strip in a lengthwise direction and a guide for guiding the strip past a cutting station in a predetermined path of advance. A cutting blade is mounted at the cutting station and is operable to sever from the strip the segments thereof that have passed the cutting station. The blade has a home position wherein it permits passage of the strip along the path of advance before severance and is movable through a cutting stroke from the home position and back into the home position. The blade has a deflecting position wherein it permits passage of the strip beyond the cutting station while deflecting the strip from the path of advance. A blade actuator is provided to move the blade into and from the home position and deflecting position and through the cutting stroke in timed relation to strip advancement.
