    摘要： A NOVEL PHOSPHATE-FREE GRANULAR POTASSIUM CHLORIDE (KCI) FERTILIZER COMPOSITION IS DESCRIBED IN WHICH THE KCI HAS EMBEDDED WITHIN IT PREDETERMINED AMOUNTS OF MICRONUTRIENT VALUES.OPTIONALLY, MACRONUTRIENTS, E.G. SECONDARY NUTRIENT VALUES AND OR A SOURCE OF THE PRIMARY NUTRIENT NITROGEN, E.G., NITROGEN-CONTAINING COMPOUNDS ARE ALSO EMBEDDED IN THE KCI THE NOVEL KCI COMPOSITION (OTHER THAN FOR THE ABSENCE OF PHOSPHORUS) PROVIDES A BALANCED PLANT NUTRIENT COMPOSITION IN THAT SNSTANTIALLY EACH KCI GRANULE IS A BALANCED PLANT NUTRIENT CONTANING PREDETERMINED AMOUNTS OF SELECTED NUTRIENTS. INCORPORATION OF THE VARIOUS NUTRIENTS IN KCI IS ACCOMPLISHED BY COMPACTINGKCI AND THE ADDED SELECTED NUTRIENTS AT PRESSURES SUFFICIENT TO CAUSE PLASTIC FLOW IN THE KCI WHILE THE KCI IS IN INTIMATE CONTACT WITH THE ADDED SOURCE OF THE SELECTED NUTRIENTS. TYPICALLY PRESSURES OF 8,000 TO 30,000 POUNDS PER LINEAR INCH ARE USED, SPECIFIC MICRONUTRIENTS EXEMPLARY OF THOSE INCORPORATED IN THEKCI ARE THE ELEMENTS BORON MANGANESE, COPPER, IRON, ZINC, MOLYBDENUM AND COBALT, KCI COMPOSITIONS DISCLOSED CONTAIN AT LEAST 0.05 PERCENT BY WEIGHT OF THE DESIRED MICRONUTRIENTS QUANTITY OF MICRONUTRIENT COMPOUND INCORPORATED IN THE KCL VARIES CONSIDERABLY AND DEPENDS UPON SOIL AND CROP DEMAND. QUANTITIES OF MICRONUTRIENT INCORPORATED CAN VARY FROM0.05 TO 50,E.G., 0.1 TO 30, WEIGHT PERCENT BASED DON KCI DISCLOSED INCLUDE CALCIUM MAGNESIUM AND SULFUR.

    摘要： A highly sensitive magnetometer consisting of at least one pair of generally rectangular core elements having square hysteresis loops is disclosed. The primary windings of each of the cores are driven by an oscillator, with the secondary windings of each core being differentially connected through a null circuit, which serves to balance the effects of background fields, and a detector to a suitable indicator. The primary windings of the cores are operated in a resonance and the secondary windings are arranged to provide a high null output which eliminates the dead band caused by the threshold value of the diodes in the output detector circuit. This high null output may be accomplished by unbalancing the core windings or by feeding a portion of the primary winding drive current, or a signal synchronous therewith, to the corresponding secondary winding, thereby permitting measurement of the small magnetic fields which previously fell within the dead band of the device. Also disclosed is a method of aerial surveying and a guidance system for off-vertical drilling using the magnetometer.

    摘要翻译： 公开了一种由具有方形磁滞回线的至少一对大致矩形的核心元件组成的高灵敏度磁力计。 每个磁芯的初级绕组由振荡器驱动，每个磁芯的次级绕组通过零电路进行差分连接，零电路用于平衡背景场的影响，并将检测器平衡到合适的指示器。 芯的初级绕组以谐振工作，并且次级绕组被布置成提供高零空输出，其消除了由输出检测器电路中的二极管的阈值引起的死区。 这个高零点输出可以通过使芯线圈不平衡或通过将初级绕组驱动电流的一部分或与其同步的信号馈送到相应的次级绕组来实现，从而允许测量先前落在死区内的小磁场 设备的频带。 还公开了一种航空测量方法和使用磁力计进行垂直钻井的引导系统。
