A T.V. camera, mounted on the arm of a teleoperator remotely controlled gping hand, is used to view an object to be grasped through an in-line semi-reflective mirror and a laterally disposed reflective mirror. Alignment of the teleoperator with the object is indicated by a single superimposed image of the object on the television viewing screen. Non-alignment of the teleoperator hand and the object is indicated by double images.

A fail-safe pneumatically operated by-pass sampling valve suitable for use n hazardous chemical processes utilizes a manually operated spool valve to initiate a pneumatically operated piston driven crank to rotate a sampling valve. The sampling valve withdraws a sample amount of fluid from a process line without disturbing normal process flow. A pneumatically connected spindle valve and a plurality of limiting valves are proximately positioned and operatively connected to the piston to automatically move the piston actuating member from a normally closed non-sampling position to a sampling position and then back to a normally closed non-sampling position.
