    Abstract: A support has a hollow tubular axial guide mounted on an end wall thereof. An operator is slidably mounted within the guide and spring biased in one axial direction or from normal unactuated position toward actuated position. Balls mounted within openings in the guide wall engage an annular shoulder of the operator to hold the operator in normal position. The balls are held in engagement with the operator shoulder by a cylindrical release member slidably mounted on the outer surface of the guide and spring biased oppositely of the operator and into engagement with the balls. A pair of seismic masses are pivoted to the support for swinging movement radially of the guide about axes located generally parallel of the guide axis. The masses are spring biased apart with respect to each other and radially outwardly of the guide into engagement with sidewalls of the support. Each mass includes a tapered elongated surface normally positioned in adjacent spaced relationship to a conical surface on a flange of the release member. Upon receipt of an acceleration pulse of predetermined amplitude and time directed generally radially of the guide, one of the masses moves radially toward the guide and the camming engagement of the tapered mass surface with the conical surface of the release member moves the release member axially of the guide to release the balls and in turn release the operator.

    Abstract: A unidirectional sensor which includes an operator mounted within a tubular guide for movement to an actuated position under a resilient bias. Primary and secondary seismic mass members surround the guide for movement axially thereat. A spring engages the secondary member to bias the secondary member into engagement with the primary member and hold the primary member in engagement with a stop to fix the weight members in a predetermined axial position. A plurality of balls are freely received within respective apertures in the guide and engage a radially tapered annular shoulder of the operator and an axially tapered internal annular wall of the primary member. Upon the application of an acceleration pulse of predetermined amplitude for a predetermined time to both weight members, the weight members move axially as the annular tapered wall forces the balls inwardly of the guide and along the operator shoulder until the balls pass through the narrower opening of the wall and release the operator for movement to actuated position. At lesser amplitude pulses, but above a minimum amplitude pulse, the secondary member moves axially of the guide while the primary member will remain stationary or move slightly axially of the balls and guide. Upon the cessation of the pulses of lesser amplitude, the secondary member moves in an opposite axial direction to impact the primary member and ensure its return to the predetermined axial position if it has moved.

    Abstract: A CYLINDRICAL SUPPORT HAS A HOLLOW TUBULAR AXIAL GUIDE MOUNTED ON AN END WALL THEREOF. AN OPERATOR IS SLIDABLY MOUNTED WITHIN THE GUIDE AND SPRING BIASED TOWARD ACTUATED POSITION. BALLS MOUNTED WITHIN RADIAL OPENINGS OF THE GUIDE ENGAGE A RADIALLY TAPERED SHOULDER OF THE OPERATOR TO HOLD THE OPERATOR IN NORMAL POSITION AGAINST MOVEMENT. THE BALLS ARE HELD IN ENGAGEMENT WITH THE OPERATOR SHOULDER BY A RETAINER SLIDABLY MOUNTED ON THE GUIDE AND SPRING BIASED AXIALLY OPPOSITE TO THE OPERATOR. AN ANNULAR SEISMIC MASS SURROUNDS THE GUIDE AND FITS BETWEEN THE RETAINER AND AN END WALL OF THE SUPPORT. THREE EQUALLY CIRCUMFERENTIALLY SPACED CONICAL DEPRESSIONS IN EACH END OF THE MASS MATE WITH LIKE DEPRESSIONS IN THE RETAINER AND IN THE SUPPORT. EACH PAIR OF MATING DEPRESSIONS RECEIVES A BALL. WHEN THE MASS RECEIVES AN ACCELERATION PULSE OF PREDETERMINED AMPLITUDE AND TIME, IT SHIFTS RADIALLY OF THE GUIDE, AND THE CAMMING ACTION OF THE BALLS MOVING WITHIN THE CONICAL DEPRESSIONS SHIFTS THE RETAINER AXIALLY AGAINST ITS SPRING BIAS TO RELEASE THE BALLS FROM THE OPERATOR SHOULDER AND IN TURN RELEASE THE OPERATOR.

    Abstract: To measure the mass flow rate of a constituent of a gaseous stream, for example, a pollutant in an engine exhaust gas, the concentration or mole fraction of the constituent is measured by an analyzer. Then a tracer gas is injected into the gaseous stream at a predetermined rate and mixed therewith and the concentration of the tracer gas is measured. Then the mass flow rate of the constituent is calculated by the equation Wc Cc Mc Wc /Ct Mt where Wc and Wt are the mass flow rates of the constituent and the tracer gas respectively, Cc and Ct are the concentrations of the constituents and the tracer gas respectively, and Mc and Mt are the molecular weights of the constituent and the tracer gas respectively. Several constituents may be monitored simultaneously in this manner by measuring the concentration of each constituent and using only the one measurement for the tracer gas.
