Abstract: ABSTRACT OF THE DISCLOSURE     This invention is directed to a process for the production of polyaryl amines containing methylene bridges.          These compounds are prepared from aryl amines and formalde-hyde in the presence of acids and water and the catalyst is simultaneously recovered.  The polyaryl amine salt solutions produced by conventional methods are mixed with the starting aryl amines to form at least partially hetero-geneous systems, optionally after the addition of water and optionally in the presence of hydrophobic solvents.          Polyaryl amines are exchanged by aryl amines to form on the one hand, mixtures of polyaryl amines and aryl amines and on the other hand, an aqueous solution of the acid in the form of a salt of the aryl amine.

Abstract: Application for Patent of JACK SACKS     for IMPULSE NOISE REDUCTION SYSTEM                 ABSTRACT OF THE DISCLOSURE        This invention describes a system and method for detecting unwanted pop and click sound signals caused by mechanical defects on a recording medium. A pair of wholly or partially correlated signals is generated from the recorded sound informa-tion by a conventional stereo pickup device.  The output signals of the stereo pickup device are combined so that desired sound signals generated by horizontal movement on the record medium are subtracted and undesired signals generated by vertical movement on the record medium are added.  The resulting undesired signal representing clicks and pops is detected as the noise signal. A gating signal starting before the leading edge of the detected undesired sound signal terminating innocuously on the sound signal, and having a width that is greater than the width of the detected undesired sound signal, is used in the system to eliminate the undesired signals.

Abstract: TITLE              CHANNEL BAR BUBBLE PROPAGATE CIRCUIT                           INVENTORS                         Edward Della Torre Witold Kinsner ABSTRACT OF THE DISCLOSURE         The magnetic bubble propagate circuit combines the forces on a bubble due to the properties of a modulated channel in a bubble material with the forces on the bubble due to a field produced by discrete magnetic poles P1 and P2 to move the bubble along a predetermined path.  The channels may be modulated in width or in depth and be of the mesa or groove type so as to have a channel with periodically spaced stable bubbles positions O which are separated by barrier positions X.  The poles P1 and P2 consist of soft-magnetic material bars which are placed either along the channel perpendicular thereto such that alternate ends of sequential bars overlap the channel between pairs of stable positions, each bar providing a pole P1 or P2, or along the channel parallel thereto such that the ends of  the  bars fall between adjacent pairs of stable positions, each bar providing a pole P1 and P2.  The propagate circuit thus has repeated pattern O, X, P1, O, X, P2.  The bars P1 and P2 are periodically magnetized-to opposite polarities by an alternating transverse magnetic field which is parallel to the length of the bars to produce a force on the bubbles which are in a stable positions to move them across adjacent barrier positions X.  When the field reverses, the bubbles move across the next barrier.  Turn-around circuits and as transfer gates which may be combined with the basic propagate circuit to form loop and minor-major loop memory arrangements may be similarly constructed.  These are made such that the pattern O, X, P1, O, X, P2 is not broken either between two parallel propagate circuits to form a loop or between a minor loop and a major loop in a memory arrangement.  The minor loop and the major loops are driven by independent perpendicular alternating magnetic fields and thus these fields control the transfer of bubbles between them.

Abstract: ABSTRACT        A precipitating agent for precipitating precious metals such as gold from aqueous cyanide solution of the precious metal ions includes aluminum powder and a reducing agent such as sodium hydrosulfite, sodium borohydride or hydrazine. The precipitating agent may also include an alkali metal carbonate, such as potassium carbonate, as an activaator. The precipitating agent efficiently reduces the precious metal ions to elemental metal for recovery and also consumes a portion of the cyanide content, which is often high in such solutions. The method of use includes adjusting the precious metals cyanide solution to a high pH, adding the precipitating agent with agitation, prefer-ably in incremental portions of the amount required. The solution is allowed to stand to permit the precipitated metal to settle, and the metal is separated from the solution.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous production line is divided into a plurality of zones, with each of which there is associated a presettable counter.  An anticipated length of a material, which has been calculated from information as to the length of the material before welding, is converted into a given number of pulse signals, which in turn are preset in this counter, with its timing being shifted a zone to zone distance.  Elongated materials which have been sequen-tially joined by welding into a continuous length of material are fed into the production line, and the length of material actually fed is detected by means of a feed length gage.  Output from the gage is converted into a pulse signal.  The length of the material actually fed is subtracted from the anticipated length of the material, i.e., the preset count value, as the material is being fed.  Thus, it is presumed that a welded point of the length of material is present in the zone where a preset count value becomes zero as a result of the aforesaid subtraction. This presumption is further corrected by means of a welded point detecting means provided in a given position in the production line.  The welded point detecting means is provided in the form of a X-ray thickness gage or temperature detector for non-contact-ing detection, without subjecting the material to physical or chemical working.
