    Abstract: A device for transducing a force into a pneumatic signal comprises an air obstructing body composed of a rigid ball and supporting disc against which a force to be transduced is applied, and an air nozzle including an opening facing the rigid ball, the air nozzle being connected to a compressed air supply unit. Compressed air from the opening of the air nozzle flows away along the surface of the rigid ball. As a result the above, the air obstructing body moves upward or downward by the difference between a compressed air force acting upon the rigid ball compressed and the applied force to be transduced. When both forces balance, the air obstructing body settles in an equilibrium position and at that time, back air pressure of the nozzle has a relationship which is proportional to the applied force to be transduced. Back air pressure is measured by an air pressure measuring instrument connected to the air nozzle as a pneumatic signal.

    Abstract: FORCE MEASURING SYSTEM HAVING A SENSING INDUCTANCE AND A MOVABLE FORCE SENSITIVE ELEMENT FOR CHANGING THE EFFECTIVE Q OF SAID INDUCTANCE. A SERVO RESTORING COIL FOR RESTORING THE MOVEMENT OF SAID MOVABLE ELEMENT IS PROVIDED. AN OSCILLATOR HAVING A TRANSISTOR WITH AN OUTPUT TERMINAL IS ALSO PROVIDED AND INCLUDES A LOADING CIRCUIT HAVING SAID INDUCTANCE COUPLED TO THE OUTPUT TERMINAL AND ARRANGED TO VARY THE EFFECTIVE LOADED WITH CHANGES IN THE POSITION OF SAID MOVABLE ELEMENT. FEEDBACK MEANS IS ARRANGED TO CAUSE VARIATION IN SAID LOAD TO CHANGE THE AMPLITUDE OF OSCILLATION AND MEANS IS PROVIDED TO APPLY THE CHANGES IN AMPLITUDE TO SAID SERVO RESTORING COIL TO OPPOSE THE MOTION OF SAID MOVABLE FORCE SENSITIVE ELEMENT.

    Abstract: A detector provides a signal for switching on the power supply of a proximately positioned transmitter upon the detection of desired information. A signal representative of the desired information is transmitted and, at predetermined times thereafter, coded signature signals are produced for transmission, these latter signals being supplied by a code generator upon the receipt thereto of pulses from a one-shot and/or repetitive interval timer. The system consumes no power in the standby mode.
