Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for the reciprocal transmission of signals through transmitting channels.  The circuit has amplifiers therein for amplifying the signals being transmitted in op-posite directions along the line.  A pair of branch determin-ing circuits are provided so that the signals which are emit-ted by one amplifier and which must be transmitted in one direction do not overdrive the input of a further amplifier which is provided for amplification of signals to be trans-mitted in the other direction.  A circuit is provided in each of the branch determining circuits for the continuous pro-duction of a reference signal which is fed to a comparator circuit connected to the input of the amplifier so that the signals arriving at the amplifier can be compared with the outgoing signals that are being transmitted in the opposite direction.  The reference voltage is controlled with respect to its magnitude and phase so that it corresponds to the voltage produced by the outgoing signals and any difference existing between the reference voltage and the outgoing signals will cause the comparator circuit to produce a signal to effec-tively prevent the outgoing signals from reaching the input to the amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE           Tracking control apparatus for a signal reproducing system of the type wherein at least one transducer scans suc-cessive parallel tracks on a record medium in which information signals, such as video signals, are recorded. The transducer preferably is of the rotary type so that, during its orbit, it is brought into and then out of reproducing relation with res-pect to the record medium. Any deviation between the scanning trace of the transducer across the medium and a given track which is being scanned is detected, and a control signal is produced as a function of this detection deviation. The trans-ducer is supported by an adjustable support which is responsive to the control signal so as to displace the transducer trans-versely of the given track by an amount determined by the control signal, A predetermined sample of the control signal is produced while the transducer scans the given track, and this predetermined sample is stored. Prior to the time that the transducer moves into a reproducing relation with respect to the medium, the stored sample is supplied to the adjust-able support so that the transducer is pre-displaced before signals are reproduced thereby.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved electrode assembly for a high-inten-sity ionizer array utilized as the first stage in a two-stage electrostatic precipitator.  Each ionizer unit employs a pair of co-axial electrodes to create a high-intensity electric field across the path of a particulate-laden gas stream.  As the gas passes through the field, it is in tensely ionized and the particulate becomes highly charged.          The ionizer anode comprises a venturi diffuser through which the gas stream flows immediately prior to entry into a precipitator stage which removes the charged particles.  The ionizer cathode is a disc co-axially mounted within the venturi throat and having an arcuate periphery. A high voltage power supply connected between the anode and cathode establishes a high-intensity corona discharge in the annular region formed between the edge of the cathode disc and the surrounding cylindrical anode surface.  Focusing electrodes at cathode potential are positioned on either side of the cathode disc and intensify the electric field along the anode wall at the fringes of the current flux band upstream and downstream from the corona discharge plane.  This substantially reduces the width of the anode surface sub-jected to corona current and minimizes anode cleaning requirements by reducing the particle deposition area.

Abstract: GROWTH OF POLYCRYSTALLINE SEMICONDUCTOR FILM WITH INTERMETALLIC           NUCLEATING LAYER                Abstract of the Disclosure A method is disclosed for fabricating a thin elemental semiconductor, e.g., Si or Ge, film with columnar grains in a filamentary structure, by the use of an intermetallic compound incorporating the elemental semiconductor to form a nucleating layer for the growth of the semiconducting film.  The semiconductor is grown from vapor phase by the technique of either vacuum evaporation or chemical vapor deposition, e.g., by decomposition of SiH4.  The semiconductor e.g., Si, is initially deposited onto a thin film of a specific metal, e.g., Pt or Ni,  on any inert substrate, e.g., SiO2 or Al2O3, which is held at a temperature, e.g., 900°C, above the eutectic point, i.e., 830°C, of an intermetallic compound and the metallic film, and below the eutectic point, i.e., 979°C, of another intermetallic compound and the semiconductor.         Deposition of the semiconductor onto the metallic film produces a layer of liquid comprising the semiconductor and metal, which increases in thickness until the metallic layer is completely consumed.  Additional deposition of the semiconductor produces a supersaturated liquid from which large crystallites of the intermetallic precipitate.  With increasing deposition of semiconductor, the crystallites of intermetallic material continue to grow until they consume all of the metal in the liquid, at which point no liquid remains.  Continuing deposition of semiconductor material results in the growth of filamentary crystallites of the semiconductor out of the intermetallic surface.  The result is a columnar film of the semiconductor with a filamentary structure originating from the crystallites of intermetallic nucleating material.
