Abstract: ABSTRACT  OF  THE  DISCLOSURE        Disclosed is a method of and system for removing micron and submicron liquid and solid particulate matter entrained in a gas stream.  The gas stream with the micron and submicron liquid and solid particulate matter entrained therein is forced through a collection media at a pressure drop across the collection media greater than ten inches water gauge.          The collection media has a void fraction in excess of ninety percent, and comprises a unitary three-dimensional network of interconnected strands of material with the strands being integrally connected at spaced apart nexus to form a skeletal outline of a multitude of interconnected open cells with each opening to each cell common to an adjacent cell.  The network has sufficient strength to prevent the force of the gas stream flowing therethrough significantly collapsing the network of strands from its unloaded state as the gas stream is forced therethrough.  The strands of the collection media are kept substantially covered with a film of collection liquid but the quantity of collection liquid maintained in the collection media is insufficient to generate incipient flooding of the collection media so that the liquid and solid particulate matter is separated from the gas stream and carried in the film of collection liquid.  The gas stream and collection liquid droplets are subsequently passed through a liquid separation device after passage of the gas stream through the collection media to separate substantially all of the particulate matter laden collection liquid droplets from the gas stream.

Abstract: METHOD AND APPARATUS FOR FAST DETERMINATION OF INITIAL TRANSVERSAL EQUALIZER COEFFICIENT VALUES                     ABSTRACT A method for determining the initial values of the coefficients of a transversal equalizer for a synchronous data transmission system, wherein a training sequence is transmitted to allow the equalizer coefficients to be adjusted to optimum initial values.  According to the method, a sequence (vi) of L elements vi,  having a periodic autocorrelation function, only the first coefficient of which is not zero, is derived from a periodic binary pseudo-random sequence (ui) of L binary elements ui having a periodic autocorrelation function, the first coefficient of which is equal to L and each of the other coefficients are equal to -1.  Then, the sequence (vi) is transmitted through the transmission channel and the initial values of the equali-zer coefficients are derived from the received sequence.  In a pre-ferred embodiment of the invention the initial values of the equalizer coefficients are derived from the received sequence through a direct method which involves the calculation of the autocorrelation matrix of samples of the transmission channel impulse responses.

Abstract: ABSTRACT       The invention is directed to freeze concentra-tion of liquid mixtures including solutions by the direct contacting in at least two stages, of the mix-ture with a miscible refrigerant.  After the con-tacting of the refrigerant with the liquid mixture, there is provided a first stage crop of substantially pure crystals of a mixture component which is separa-ted from the mother liquor.  The mother liquor is then further cooled and crystallized in further stages.          Any crystals from said further stages are returned to the first or proceeding stage.  This concentrates the second stage and further stage mother liquors.      This process is applicable to the freeze concen-tration of juices, coffee or tea extracts and beers.          It also may be utilized for the purification or bra-ckish water.  The purity Or the first stage crystals is assured by controlled crystal growth.  The successive stages provide for a complete concentration of the residual matter in the mother liquor.  When the residual matter in the mother liquor is the desired product, it is recovered in very concentrated form.  Should the crystals from the first stage be the desired product, their high degree of purity is advantageous.

Abstract: ABSTRACT   An internal combustion engine ignition apparatus includes a secondary spark plug having a center electrode to which a high voltage is applied.  A cylindrical peripheral electrode surrounds the center electrode and has peripheral openings.          Upon the formation of a corona discharge due to the high voltage applied to the center electrode, a strong ionic wind and convection of an air-fuel mixture are produced.  The ionic wind causes fuel constituents to be gathered in the vicinity of the peripheral electrode thus preventing production of hydrocarbons due to cooling or quenching of the fuel on the combustion chamber wall.  Initial ignition of the air-fuel mixture is by means of a main spark plug.  The resultant flames are propagated to the corona discharge portion of the secondary spark plug.  The corona discharge is then changed to secondary continuous spark discharge, to thereby positively fire the stratified air-fuel mixture.
