Abstract: ABSTRACT       An improved ozone generator includes a cryogenically cooled reaction chamber in which gaseous oxygen well below the boiling point of liquid oxygen is subjected to a corona discharge and forms liquid ozone.   The discharge portion of the reaction chamber holds a body of liquid ozone to block the flow of unreacted oxygen from the reaction chamber.   A bed of glass particles within the body of liquid helps to suppress explosive decomposition of the ozone.   A temperature gradient across the discharge portion of the reaction chamber permits the ozone to volatilize to a gas and exit the reaction chamber in a smooth, controllable manner.

Abstract: ABSTRACT OF THE DISCLOSURE       A wide-band automatic fine tuning (AFT) circuit capable of a ?2 MHz pull-in range without false lockups responds to the output of a picture carrier discriminator, a sound carrier discriminator and a vertical synchronizing signal sensing means to operate a reversible digital counter in either its count up or count down direction depending upon the relationship of the outputs of the two discrimina-tors and the synchronizing signal sensing circuit.  The output of the counter is supplied to a digital-to-analog converter which produces a tuning control voltage used for controlling the frequency of operation of the local oscil-lator of the receiver.  The output of the digital-to-analog converter is added to a conventional AFT voltage which main-tains the desired tuning once it has been established by the wide-band AFT system.

Abstract: ABSTRACT OF THE DISCLOSURE    In a radio communication system having a base or command station and one or more controlled stations, the base station transmits outbound binary messages to the controlled stations in order to make an inquiry or give a command to the controlled stations.  Each controlled station responds to its address message with an inbound binary message.  In order for the stations to synchronize with messages transmitted to them, each outbound message and each inbound message includes three spaced binary synchronizing code words having nine bit values 011100100 in sequence, nine additional bit values 100011011 in sequence, and nine additional bit values 100011011 in sequence.  Or, the three synchronizing words may have the bit values 001001110, 110110001, 110110001 respectively. These synchronizing code words enable controlled stations to synchronize with an outbound message and enable the base station to synchronize with an inbound message quickly and reliably.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a reference rectifier in a multifrequency  signal receiver in order to obtain a correct detection of the two signalling frequencies in an incoming voice frequency signal independently of disturbing signals of varying frequency and duration.  The rectifier comprises a first signal path including a first circuit for example, a peak rectifier for creating a first signal level in dependence on the incoming signal level.  This signal level is compared with the signal component having the frequency equal to one tone in the incoming voice frequency signal.  The rectifier also comprises a second signal path including a second circuit for example, a mean value creating circuit which, in dependence on the incoming signal gives a second signal whose level is smaller than said first signal level.  A number of diodes is connected between the outputs of the receiver and the first signal path to inhibit the output signal from this signal path in dependence on the comparison between the signal level from the first signal path and the signal component having the frequency equal to one tone in the incoming voice frequency signal.
