Abstract: A multiplexer for the transmission of signals on different carrier frequencies includes a Butler matrix with a set of delay elements secured to output terminals of the matrix. Each of the delay elements differs from the other delay elements in that the delays imparted to signals by each of the elements differ by an integral number of delay units. The selection of frequency values is made in accordance with the increment in delay unit so as to develop incremental values of phase shift which compensate for phase shift introduced by the phase shift taper of a Butler matrix. This permits summation of signals from plural input ports of the matrix without the generation of intermodulation products among the various signal channels.

Abstract: An apparatus (30) for performing multiplications with reduced power includes an arithmetic logic unit (44) and a decode block (41) for performing an equivalent of a multiply instruction. A frequently-encountered multiply instruction occurs between a variable and a known constant. If the known constant is positive or negative one, the decode block (41) enables the arithmetic logic unit (44) to either add the variable to zero, or subtract the variable from zero, in response to the sign bit of the known constant. In response to a multiply and accumulate instruction between a variable and a known constant of positive or negative one, the decode block (41) enables the arithmetic logic unit (41) to either add the variable to the prior accumulated result or to subtract it therefrom, in response to the sign bit of the known constant. In either case, a high-speed multiplier (45) is disabled and its power saved.

Abstract: A method of quantitative analysis of drilling fluids comprising subjecting an untreated wet sample of the fluid to a reflectance infrared spectroscopy technique, typically attenuated total reflectance spectroscopy, and comparing the spectrum obtained with spectra obtained from calibration samples of fluids of known composition. The sample can be obtained directly from the flowing mud with no preparation or alternatively the sample might comprise a prepared sample which is re-suspended in a liquid phase carrier. The sample can also be analysed for non-spectral properties which might also provide useful information in conjunction with spectral data. The method requires little or no sample preparation and can be used to quantitatively analyse both water-based and oil-based drilling fluids using a continuous in-line and/or on-line arrangement.

Abstract: A long-lived, lightweight, and quickly and precisely charged storage capacitor power supply capable of stably supplying electric power to a load. The power supply has a capacitor block consisting of capacitors connected in series , in parallel or in any combination of series and parallel. The power supply further includes a charging circuit for charging the block, a charging power supply connected with the block via the charging circuit, and a charge-limiting circuit. This limiting circuit detects the voltage across the terminals of the block and limits charging of the block if the voltage reaches a given value. One embodiment of the invention further includes a charge-limiting circuit, a full charge-detecting circuit, and a residual electricity-detecting circuit connected in parallel with the block. The charge-limiting circuit senses that the voltage across the terminals of the block exceeds the given value and causes the charging current to bypass the block. The full charge-detecting circuit senses that the charge-limiting circuit is operated and determines that full charge is attained. The residual electricity-detecting circuit finds the residual electric power from the voltage across the terminals of the block. Another embodiment has a first and a second capacitor blocks. The voltage across the terminals of the first block is detected. The first block is charged from the second block until the detected voltage reaches a given voltage. The first block supplies electric power directly to the load.
