Title: Gamma ray well logging  for radial tracer distances
Inventor: GADEKEN LARRY L
IPC: E21B47/10
Filed: 1990-03-08
Abstract: Gamma ray well logging to obtain relative distance indications of tracers from the well bore comprises separating a measured gamma ray spectrum into component parts attributable to individual tracers, using standard spectra, and then obtaining the relative distance indicators from those parts of the spectrum. For cased borehole, using standard spectra as a guide, the proportions of the borehole component and the formation component can be determined and a composite spectrum obtained for each individual tracer by adding the borehole and formation components together. A Compton ratio R c  of gamma ray counts in an energy region of the spectrum which is sensitive to Compton scattering to gamma ray counts in an energy region of the spectrum which is not sensitive to Compton scattering is then obtained. By a linear transformation which parameterizes the Compton ratio R c  with the inverse square of the annulus diameter of a distributed region of tracer surrounding the well bore, a relative distance indication of the distribution of each tracer with respect to the well bore is obtainable for each tracer.

Abstract: An echo canceller modem (2) having a fast training echo canceller (44) is described. The echo cancellation coefficients are computed by taking correlations between a complex, periodic training signal sequence and a real component of the corresponding echo signal. The modem includes a receiver circuit (28,30) which detects a signal on a channel possibly including an echo. An echo canceller (50,52) estimates the real component of the echo signal. Training circuitry (60) applies the complex training sequence to the channel and takes correlations between the training sequence and the real component of the corresponding echo signal. In the preferred arrangement, the modem also includes a computational element for computing the period of the periodic sequence, generating the complex periodic training sequence in real time and for computing a phase roll frequency (56) based upon the computed echo cancellation coefficients.

Abstract: The binary multiplier circuit for obtaining a product of an M-bit multiplier and an N-bit multiplicand includes a mul­tiplier circuit which produces a matrix of original summand bits having M rows and M+N columns and a matrix reduction circuit. In the matrix reduction circuit, for every column of the matrix having three or more original summand bits, groups of three bits are input into full adder circuits which output a sum bit for that column and a carry bit for the col­umn in the next most significant bit position. For every column having three or fewer original summand bits, and hav­ing the least significant column position that is not yet reduced to two or fewer bits, groups of two bits are input into a half adder circuit which outputs a sum bit for that column and carry bit for a column in the next most signifi­cant bit position. Iterative reductions are performed for each column by using full adder circuits for every group of three bits in a column and by using a half adder circuit for any remaining group of two bits in a column. The reduction continues until each column of the matrix is reduced to two or fewer bits. The remaining two rows of bits can be input to a two-stage carry-propagating adder circuit to output a sum equal to the product.

Abstract: A method and apparatus provide for the continuous digestion of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, with increased sulfidity. When black liquor is withdrawn from the continuous digester (32), instead of merely passing it to a pair of flash tanks (25, 26) and then to recovery, the concentrated liquor from a first flash tank is fed to a vessel (15) in which the comminuted material is slurried with a liquid. Since the black liquor remains in intimate contact with the chips for a significant period of time, the lignin in the chips is partly sulfonized. Ultimately the black liquor is replaced with white liquor or the like, and the separated out black liquor is circulated to recovery or disposal. A high pressure feeder (16) and a solids/liquid separator (36) are utilized.

Abstract: The process is used to prepare oligo- and polypeptides in a cell-free translation system which contains besides a buffer solution process components which are involved in the ribosomal translation processes in the initiation, elongation and/or termination phase. In order to improve the efficiency of synthesis, it is provided that the individual ribosomal translation processes are controlled in a phase-directed manner and are at least partially synchronised by changes in the concentrtion of at least one of the process components at intervals in time. This takes place in such a way that during at least two of the three phases the prevailing conditions are more favourable with regard to at least one process component for the progress of the particular phase than they are in at least one of the two other phases. <IMAGE>     Fig. 1: Number [n] of polypeptide copies synthesised in five hours per mole of mRNA of BMV with varying duration (in minutes) of the control cycle [t] Curve A: Number of synthesised polypeptide molecules on cyclic alteration of the concentration of ATP (test series 1) Curve B: Number of synthesised polypeptide molecules on cyclic alteration of the concentration of all process components contained in the system (test series 2) Control: Number of synthesised polypeptide molecules with a constant concentration of all the process components contained in the system (control)
