Abstract: 1,081,958. Pure fluid amplifier. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan.4, 1965 [Jan. 7, 1964], No.51755/64. Heading G3H. [Also in Division G4] A fluid pulsed-jet device comprises a pulsed power jet 1 leading to an interaction chamber 4 which receives control signals from inlets 5 or 6. The control signals are supplied as a low pressure steady flow and a signal from inlet 5 will form a clockwise vortex in the chamber 4 so that the pulsed jet issuing from nozzle 1 flows to the outlet 14, 7 and locks on to the wall 2. The control signal from inlet 6 has the reverse effect to direct the jet to the outlet 3, 8. However, if the control signal is changed from inlet 5 to 6 while the pulsed jet is flowing, this prevents the forming of the anti-clockwise vortex until the pressure pulse ceases and the vent pulse is then directed to outlet 3. Passages 9a, 9b are provided to equalise static pressures. In a modification, the device is asymmetrical and only one control signal passage is then necessary. Such a device may be used in a binary counter or shift register (see Division G4).

Abstract: In a ring communication system comprising selectively connectable data stations, each station has connecting circuitry including a phase-locked loop arrangement (111) which is frozen at its current frequency and phase in response to a signal interruption caused by a station insertion or removal operation. Control logic (113) generates a freeze control signal in dependence of the signal energy status on input lines (75). This control signal activates gates (149, 151) and switches (155, 157) to interrupt change control signals of the phase-locked loop circuitry and to keep an oscillator control voltage at a given value. The control logic also provides an auxiliary data signal during the freeze interval which is applied to the ring to keep stations downstream in synchronism. By this method and arrangement, undesired reactions and excursions of the phase-locked loop circuitry in response to a signal energy outage are prevented, and synchronization can be rapidly regained after station insertion or removal.

Abstract: Status and alerting signals are distributed in a TDM communication system in a split-up form in broadcasting mode: the cadencing information of all status/alerting signals is distributed in word format on an existing signaling channel, each bit of such a word representing the scan value of a different status/alerting signal at a given moment. The basic tone common to all status/alerting signals may be distributed in coded form on a special or a common channel like voice signals. Any terminal instructed to do so will regenerate any required tone signal for itself.

Abstract: A closed loop communication system in which the terminals are grouped into priority classes. Any terminal can seize a free channel if certain priority conditions exist. A channel (frame) is always preceded by a header comprising a priority request field and a priority grant field. The request field has n bits assigned to the n priority classes; a terminal requiring service sets that bit to "1" which corresponds to its class. Thus, the controller receives a compiled overall request and inserts, for the next cycle, into the grant field an indication as to which priority class or classes are now allowed access to the channel. This is accomplished by shifting the contents of the request field to the grant field. A terminal can only seize the channel if its priority class is allowed for that cycle by the grant field, and if the channel is still free.
