Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for interrupting the opera-tion of a slurry heating furnace is disclosed.  The interuption apparatus includes cokinq detecting means, first controlling means, second controlling means, furnace temperature detecting means and third controlling means.  The slurry, which flows through heating tubes extending through the body of the heating furnace, contains solid (coal), liquid (solvent) and gas (hydrogen gas) phases.  To interrupt the operation of the furnace, the first controlling means first stops the burner of the furnace upon the coking detecting means detecting the presence of coking, and then the second controlling means stops the supply of the solid and liquid phases.  However, the gas phase is made to con-tinue to flow through the heating tubes until the fur-nace temperature detecting means has detected that the furnace temperature has fallen below a safe level, at which time the third controlling means halts the flow of the gas phase.

Abstract: Abstract of the Disclosure A self-clocking encoding technique for synchronous transmission of digital signals, and apparatus therefor.          In an exemplary embodiment, the encoding technique utilizes relatively positive and relatively negative pulses of fixed, predetermined duration.  For electrical pulses, the point of reference is preferably a zero baseline.  At the leading edge LEi of the ith bit cell, the value of the ith bit is encoded as a positive pulse in the case of a logical "1" (e.g., 82A) or a negative pulse (e.g.' 82B) in the case of a logical "0" (Step 41, 42A, 42B).  Further, if the next subsequent (i.e., (i + 1)th bit has the same value, a pulse of the opposite polarity is injected into the ith bit cell after the leading edge pulse (e.g., 82D).  Thus, positive and negative pulses alternate and the information content of the encoded signal has no d.c. component; this facilitates a.c. coupling.  Further, the encoding technique is bit-rate (i.e., frequency-) independent and usable over a wide range of bit transfer rates.  The receiver can synchronously decode the signal if it knows the pulse width; it need not know the sender's transmission rate and indeed, bit transmission rate may even change from one bit cell to the next.    For a fiber optic implementation, a non-zero baseline is used.  The optical zero output level replaces the electrical negative pulse level, the half-maximum optical output level replaces the electrical zero level and the maximum optical output level replaces the electrically positive pulse.

Abstract: ABSTRACT OF THE DISCLOSURE          A magnetic field gradiometer includes a pair of coils, encompassing different regions of space. A SQUID is provided to detect a difference in flux linking the coils thereby to provide a measure of a magnetic field gradient between the coils.   A control element of a superconducting material is provided in the vicinity of the coils and a heater is controlled to vary the proportion of the element assuming the superconducting state.   By suitably varying this proportion the balance condition of the coils can be altered.          The control element may operate in a feed back circuit.   A coil subjects both coils to an alternating magnetic field at a preset frequency.   A component in the output of the SQUID having this frequency is used to control the heater.

Abstract: ABSTRACT OF THE DISLOSURE     The  high bit-rate  coupler  is  connected between a  PCM channel bidirectional  multiplex  and  a  packet  switching  unit.  Each  channel carries packet words, such as octets, grouped in frames separated by flags 01111110.  The coupler processes the first level related to the bits  of  the  frame  level  of  a packet  exchange procedure.  For  each received frame, the coupler extracts the filling zeros from the received words between the flags, controls a frame checking sequence included at the end of each frame, counts the realigned words without filling zeros to be transmitted to the switching unit and detects the flags and the start and end of the frame. At the transmitting end, the coupler inserts filling zeros in each transmitted frame when detecting six contiguous bits "1" in the words delivered from the switching unit, derives the frame checking sequence, transmits the desaligned words with the filling words, and produces flags. The memory capacity of the coupler is reduced to  the  characteristics  or  contexts  for  processing  a word  in  each channel. Processing means are common to the packet mode channels and processes progressively the received words and the transmitted words without storing of entire frames. A memorizing means of the coupler has as many memory  cells  as  channels  for memorizing  in each  cell  the contexts written  after  a word  of  the  respective  channel  has  been processed, and read for the next word in the respective channel to be processed after the other channels have been processed, at the rate of one word per channel.

The inverted imbricated product formation leaving the deflection device is inputted from below to a winding core to be wound-up thereon to form a second product package.  By inverting the imbricated product formation due to its passage through the deflection device there is achieved the result that in the imbricated product formation supplied to the winding core the leading edges of the printed products are positioned on top so as to face the second product package.   Consequently,  a  compact  second  product package is formed in which the printed products are not able to become displayed by slipping.

Abstract: ABSTRACT        An echo canceller for cancelling echos which result from impedance mismatching in a two-wire/four-wire conversion circuit.  The prior art employed an input terminal, an output terminal, a transmitter section, a receiver section, a digital-to-analog converter, an adaptive digital filter, a subtractor, a sample hold circuit, an analog-to-digital converter, a multi-plier, a low pass filter, a hybrid circuit and a two-wire communi-cation path, for the purpose of generating a replica of the echo signal to cancel such echos.  A method has also been proposed which employs a polarity discriminator circuit instead of an analog-to-digital converter, and utilizes approximation alogrithms to correct an adaptive digital filter tap coefficient using the signs of an error signal.  In order to carry out this alternative method, the invention employs a fast convergence system comprising a circuit for generating an echo replica in response to a trans-mit signal, a circuit for producing a difference signal by sub-tracting the echo replica from a signal which contains a receiver signal and echo, a circuit for multiplying and  averaging the difference signal and a polarity of the echo replica, a circuit for absorbing a fluctuation in an absolute value of the averaged output, and a circuit for adaptively varying a tap correction amount of a filter of the echo canceller in response to an output of the fluctuation absorbing circuit.
