摘要： A method of assaying the compressive strength of rock comprises testing a primary plurality of rock samples of similar lithology, at least some of which have different porosities, to determine, for each sample respectively, values corresponding to compressive strength and porosity. A first series of pairs of electrical compressive strength and porosity signals, the signals of each pair corresponding, respectively, to the compressive strength and porosity values for a respective one of the samples, is generated. These signals are processed by a computer to extrapolate additional such pairs of signals and generate a second series of electrical signals corresponding to compressive strength as a function of porosity. The second series of signals may correspond to unconfined compressive strength, and may be further processed to generate a cumulative series of signals, using electrical adjustment signals corresponding to other conditions affecting the compressive strength of the rock.

摘要： A drill bit (10) includes at least two truncated conical cutter assemblies (20) rotatably coupled to support arms (18). The truncated conical cutter assemblies (20) are frusto-conical or conical frustums in shape, with a back face (60) connected to a flat truncated face (22, 62) by conical sides. Primary cutting elements (24) are arranged in a predetermined pattern on the flat truncated face (22, 62). The teeth (26) of the cutter assemblies (20) are spaced from cutting elements (24) of other cutter assemblies (20). The primary cutting elements (24) cut around a conical core rock formation (40) in the center of the borehole, which acts to stabilize the cutter assemblies (20) and urges them outward to cut a full-gage borehole. Secondary cutting elements (52) are mounted in the downward surfaces of a dome area (50). The secondary cutting elements (52) cut down the free-standing core (42) when the bit (10) advances.

摘要： Oxygen sensor deterioration is detected by initially counting the number of fuel units required to change the output voltage of a nondeteriorated sensor between first and second voltages, and subsequently counting the number of fuel units required to change the output voltage of the sensor between the first and second voltages, as the sensor ages, until a subsequent count exceeds the initial count by a given amount. The method detects when the air/fuel ratio desired for normal engine operation drifts outside acceptable tolerance. The method detects and stores a first difference between air/fuel ratios, corresponding to first and second sensor output voltages, and then subsequently detects a second difference between air/fuel ratios, corresponding respectively to the first and second sensor output voltages. When the second difference exceeds the first difference by a given amount, deterioration is indicated.
