Abstract: MULTIPLE TEMPERATURE AUTOREGULATING HEATER                   ABSTRACT OF THE INVENTION     A multiple temperature autoregulating heater com-prises a laminate of a conductive material, a first ferromagnetic layer on a surface of the conductive material and a second ferromagnetic layer insulated from the first layer.  The layers have different Curie temperatures.  A switching device is provided to connect one or the other of the layers to be energized from a constant current source.          The device autoregulates in the region of the Curie tempera-ture of the selected layer.  The conductive material may be non-magnetic (copper) or a low resistivity ferromagnetic material having a Curie temperature well above the Curie temperatures of the autoregulating layers.  In the latter case, a thin layer of copper or the like may be interposed between the surface and the conductive ferromagnetic material to further increase conductivity.  The device may be provided with multiple ferromagnetic layers to provide multiple different autoregulating temperatures.

Abstract: ABSTRACT     An improvement to a Viterbi-type decoder for decoding convolutional error-correcting codes whereby decisions regarding which predecessor state to a given state most probably corresponds to the best path terminating in that given state are stored in association with that given state and not in association with the best path. Paths are reconstructed by searching through such stored decisions.  Such searches are used to recover a number, possibly greater than one of data symbols for later output from the decoder.  The larger this number, the less frequently a search need be carried out.

Abstract: ABSTRACT         This invention provides a line protection switching system of improved reliability and decreased switching time.  In order to increase the reliability, the service signals are sent in parallel via several transmission lines, using a service bit area of PCM bit frames.  Unlike prior art systems the present system switches a failed transmission line to a stand by lines at a station where a fault is detected before waiting for the switching of the opposite station to be completed.  At the same time, the switching command is sent to the opposite station.  If the switching of the opposite station fails, the station commands retry of the switching but if it fails again, the station switches the transmission line to the initial state.  Since a low priority signal is transmitted through the stand by line, the total system can be economized.

Abstract: CONSTANT-PERCENT BREAK    PULSE CORRECTOR            Abstract Constant-percent break interval pulse correctors insure that the break interval of a dial pulse subsists for a substantially constant percentage of the total dial pulse interval; i.e., break interval plus make interval.  The constant-percent break interval pulse correction of the first pulse in a string of pulses is realized by employing an up/down counter which is controlled to count up at a first clock rate for a first predetermined inteval from the beginning of the dial pulse, then to count down at a second clock rate for a second interval from the end of the first interval to the beginning of a subsequent dial pulse and then to count down at a third clock rate until a predetermined count is reached, e.g., zero.  The second clock rate is the difference between the third and first clock rates.        In one embodiment, proper correction of the last dial pulse in a string of dial pulses is realized by employing a plurality of such up/down counters.  A first counter is triggered by the leading edge of the first dial pulse in the string.  Thereafter, each of the up/down counters is triggered by the trailing edge of the prior dial pulse being corrected.

Abstract: A process for automatically going into the mode for increased suction extraction of the gases emitted by the tanks of series for the production of aluminium by igneous electrolysis using the Hall-Heroult process, each tank being closed around its periphery by a plurality of removable covers which are disposed in substantially sealed relationship with each other and between each thereof and their support means on the periphery of the tank, the gases being collected over each tank by at least one duct connected to a centralized suction extraction system. The temperature of the gases in the duct is continuously measured. Opening of at least one cover gives rise to an abrupt drop in temperature, which makes it possible to put the system into the increased suction extraction mode, which will be automatically stopped when, all the covers being closed again, the temperature of the gases will substantially resume its initial value. The power required for the suction system is thus substantially reduced.

Abstract: ABSTRACT      To prevent unacceptable untwisting of the outer helically wound wires of an overhead electric conductor whilst it is being strung under tension between towers, a flexible weighted device is connected between the leading end of the conductor and the trailing end of a flexible pulling line.  This device comprises a flexible elongate member built up of at least three flexible rods connected end-to-end, each of which rods has freely pivotally connected to one of its ends an elongate counterweight having a transverse cross-section of substantially C-shape.  When tension is applied to the flexible line to draw the conductor into position and before the conductor is secured to dead end clamps, each elongate counterweight will be suspended downwardly from the flexible rod solely under the action of its weight to prevent unacceptable untwisting of the wires and, as the flexible elongate member is drawn through a stringing block, each elongate counterweight in turn will be caused to pivot upwardly to lie alongside, and pass through the stringing block with, its associated flexible rod.
