Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE            Title:     TOGGLE CONTROLLED SERVO SYSTEM          Inventor:  HUBERT (N.M.I.) BLESSING                           ABSTRACT         Digital control signals can be accepted and translated directly into low inertia, high torque intermittent rotary motion by this fast time response apparatus which comprises a low mass, rotatably mounted driving member, a source of driving torque such as a torque motor, a low rotary inertia torsion member which interconnects the driving member with the torque member to there-by apply torque to rotate the driving member, reciprocatably operated escapement means for controlling the rotation of the driving member, and a two-ended toggle linkage connected at one end in an operating relationship with the escapement means, and at the other end to a mechanism which supplies a reciprocating driving force.  The toggle linkage has a normally flexible knee joint which can be selectively locked by electromechanical means to which the digital signals are supplied.  When locked, the toggle linkage transmits a reciprocating driving force from one end, thereby triggering the escapement means so that the driving member is selectively, incrementally rotated under power from the torque motor through the torsion member.

Abstract: ABSTRACT   A dispenser for liquid, gaseous or powdered materials comprises a pressure vessel containing an upper tank containing material to be dispensed and a lower tank containing propellant.  The material tank is movable along the inside walls of the pressure vessel in sealing engagement with the inside walls and is provided with an easily frangible portion at its upper end.  The propel-lant tank is a rigid tank which holds the propellant under pressure.  The bottom of the pressure vessel has a manually operable pricking member which when operated pierces the propellant tank to release the propellant which forces the material tank upwardly.  A further pricking member which may be a nozzle tube at the top of the pressure vessel then engages and rips open the material tank.  The material can then be dispersed in the usual way by operating a finger controlled valve.  Both tanks may be replaced with full ones after use simply by unscrewing the bottom of the pressure vessel.

Abstract: Abstract Disclosed is a digital radio paging communication system having a transmitter and a plurality of receivers.  The transmitter generates a preamble signal, a synchroniæation signal, a plurality of calling signals and a stabilization signal, respectively, which are arranged into a sequence of first signals including the preamble signal and at least one batch, the batch including the synchronization signal and the plurality of calling signals which are divided into a plurality of groups, each group having the stabilization signal at the leading portion thereof.          A carrier wave is modulated with the sequence of first signals and then transmitted.  Each of the plurality of receivers is adapted to receive the modulated carrier wave and demodulate it into the sequence of synchronization signals and is responsive to at least the demodulated preamble signal and stabilization signal for providing a reference voltage.  The demodulated sequence of synchronization signals is converted into the sequence of preamble signals with the reference voltage.  Power is supplied intermittently to at least parts of the receivers in response to a first control signal and continuously to at least in response to a second control signal.  The second control signal is provided upon detection of the preamble signal and the group assigned to its own receiver, and the first control signal is provided upon detection of the synchronization signal.  The system according to the invention is of high reliability and low power drain.
