Abstract: A. Tedeschi - Case 3 MERCURY-WETTED SEALED CONTACT SWITCH     Abstract of the Disclosure The possibility of contact bounce in an electrical switch is minimized by transferring energy from an armature of the switch to a damping liquid.  An arrangement for damping the armature by such a transfer is particularly suited for use with a mercury-wetted sealed contact switch. The switch includes first and second spaced terminals embedded at opposite ends of a cylindrical envelope.  The armature is located in the space between the two terminals.  It is hinged by a thin leaf spring at the first terminal and is normally positioned to form a gap with the second terminal.          Operation of the switch to close and reopen the gap results from an application and a removal, respectively, of a magnetic field through the terminals and the armature.  Mercury wets the contact points between the second terminal and the armature.  The mercury is supplied from a pool located at the first terminal.  To dampen the motion of the armature, a damping member is rigidly coupled to the armature and extends from the armature into the pool of mercury.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE           A two-speed pneumatically powered rotary nut runner having an auxiliary motor, and a main motor axially offset from the auxiliary motor and being drivingly connected thereto by a reduction gear cage.  An output spindle is provided for engagement with a drive shank for setting of a threaded fastener, and an intermediate spindle, drivingly connected to the auxiliary motor, is coupled to the output spindle by plane-tary gears.  A torque signal assembly is operatively associated with the main motor and is operative upon reverse rotation of the main motor to generate a pneumatic signal indicative of such reverse rotation   Reverse rotation of the main motor is caused by the auxiliary motor when it has exerted predetermined final torque upon the threaded fastener.  The fact that the main motor is axially offset from the auxiliary motor, allows the rotor of the main motor to be of smaller diameter.  This, coupled with reduced speed of rotation of the reduction gear cage by reason of a spur gear coupling with the main motor output shaft, provides a reduction in kinetic energy at lower torque values without errors in torque readings because of stored energy in the rotating parts.
