Abstract: NOISE BLANKER WITH VARIABLE RATE SHUT-OFF AND/OR VARIABLE BLANKING THRESHHOLD LEVEL                          ABSTRACT      A noise blanker circuit for a stereo radio receiver is disclosed herein.  The noise blanker circuit detects noise impulses in a received radio signal.  When the magnitudes of these detected noise impulses exceed a predetermined thres-hold level corresponding noise blanking pulses are produced which are coupled to a gate means.  The gate means receives the received radio signal and selectively passes and blocks this signal in response to the noise blanking pulses such that the output of the gate means is essentially free of noise impulses.  A manually adjusted actuator is provided for selectively altering the predetermined threshold level of the noise blanker circuit such that the most efficient mode of noise blanking can be implemented.  In addition, rate shut-off circuitry is provided to prevent the pro-duction of noise blanking pulses when the detected noise impulses occur at a repetition rate exceeding a maximum repetition rate.  The manually adjustable actuator also selectively determines the value of this maximum allowable repetition rate and thereby also selectively implements the most efficient mode of noise blanking.  The manually adjust-able actuator is illustrated as comprising either the tone control actuator or the stereo-monaural selection switch actuator of a radio receiver, whereby control of the noise blanker circuit is implemented without adding an additional control to the stereo radio receiver.  In addition, an embodiment of the present invention illustrates the use of a stereo decoder means of the stereo radio receiver to select the predetermined threshold level and/or the maximum repetition rate of the noise blanker circuit.

Abstract: MEANS AND METHOD FOR FORMING AND ENLARGING HOLES IN SOIL              ABSTRACT OF THE DISCLOSURE        A hole is formed in soil by penetrating it with a tool comprising a shaft having a tapered point or auger of relatively small cross section attached to its lower end, and a series of outwardly pressing rams mounted on the shaft above the tapered point.  The rams are effective successively to enlarge incrementally by outward compaction or displacement of the soil, the hole intially formed by the tapered point or auger.  Full hole dimension above the tool is maintained by reason of the fact that the soil is incrementally compacted and compressed to resist collapse.  If desired, the integrity of the hole may be preserved with the aid of a following shield, or the hole may be filled with soil stabilizing fluid such as drilling mud.  After formation of the hole, the tool is withdrawn and the hole may be filled with concrete to form a load supporting column or it may be left as an open shaft.

Abstract: ABSTRACT OF DISCLOSURE            Disclosed is a process for making wine in commercial quantities wherein the skins and seeds of the destemmed grapes are centri-fugally separated from the grape must and left almost entirely free of moisture.  The grape must is subsequently enzymatically depectinized.  The depectinized grape must is then cleaned of substantially all insoluble colloids and fermented into wine, using only a minimum, if any, of sulfur dioxide or other bact-eriological retractant.  The skins and seeds are then separated by wind  sifting, or screening, to make usable by-products.          Also, for additional flavor and for red wines, color can be extracted from the segregated skins.
