Abstract: ADPCM ENCODER/DECODER WITH ZERO CODE SUPPRESSION            Abstract of the Disclosure An ADPCM encoding/decoding arrangement produces n-bit ADPCM codes which have 2n-1 possible codes, excluding the all-zeroes code.  A range of error signals about zero is quantized by the encoder as a non-zero ADPCM code.  In order to avoid such non-zero codes resulting in undesired changes of predictor coefficients of an adaptive predictor of the arrangements updating of the predictor coefficients in dependence upon a reconstructed error signal derived from the ADPCM signal is inhibited when each such non-zero code occurs.

Abstract: EQUALIZATION SYSTEM FOR MODEMS IN A POLLED ARRANGMENT            ABSTRACT     In a system in which a central modem individually polls a number of remotely located modems for data, an adaptive equalizer in the central modem is initially trained to minimize communication link interference from a remote modem and the equalizer develops a set of equalization coefficients based on the initial training which is transmitted to the remote modem and stored there for future use while the central modem goes on to do the same with other remote modems. When a remote modem is polled, the stored equalization coefficients are used to set the adaptive equalizer of the remote modem so the adaptive equalizer of the central modem does not have to be retrained for each individual remote modem.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention is related to improved nucleic acid reagents comprising arrays of nucleic acid fragments and com-binations of such fragments.  The preparation of such fragments by recombinant DNA techniques and their use in hybridization methods is also described.  By making different combination of the arrays of nucleic acid fragments - some labeled and some affixed to solid carriers, it is possible to create kits for the identification of e.g. venereal diseases.  The improved nucleic acid reagents comprise two series, one labeled and one affixed to a solid carrier of at least two but preferably more arrays of alternating nucleic acid fragments, which are sufficiently homologous to sequences in the nucleic acid to be identified.  Nucleic acid fragments belonging to different series must not be homologous to each other.  The invention is especially related to arrays of nucleic acid fragments prepared from the recombinant plasmid pXTH1220 (DSM 2825), comprising DNA from the Chlamydia  trachomatis L2 serotype and from the recombinant plasmid pKTH1271 (DSM 2825) compris-ing DNA from the cytomegalovirus (AD 169, ATCC VR-538)-(CMV). Sandwich hybridization tests performed with arrays of nucleic acid fragments are at least four times as sensitive as sand-wich hybridization tests performed with reagents belonging to the prior art.

Abstract: ABSTRACT Darlington transistor arrangement.           The emitter of an input transistor (T1) of a Darlington transistor is connected to the base of an out-put transistor (T2). The collector of the input transis-tor (T1) is connected to the input of a current amplifier circuit comprising a third transistor (T3) arranged as a diode and having a first resistor (R1) arranged in its emitter circuit, and a fourth transistor (T4) having its base is connected to that of the third transistor (T3) and having a second resistor (R2) arranged in the emitter circuit. The collector of the fourth transistor (T4) is connected to the base of the output transistor (T2). The ratio between the resistance values of the first and the second resistors (R1, R2) is larger than the ratio be-tween the emitter areas of the fourth and the third tran-sistor (T4, T3). Thus, for small currents a low and for large currents a high current gain is obtained, so that the current gain factor of the output transistor (T2) which decreases for large currents is compensated for partly. Moreover, the base current of the input transis-tor (T1) remains small in the case of large output cur-rents.     Fig. 2.

Abstract: Abstract Given the method, the pairs of circular knives (4,5) of a longitudinal cutter apparatus are displaced on rails (7) proceeding transversely relative to the web, being displaced thereon by prescribable positioning distances from an outer, apparatus-fixed bench mark up to a carriage-fixed bench mark. In order to be able to take the alterred position of the cutting edge (19) which may have arisen under given circumstances due to re-grinding into consideration, the distance of the cutting edge (19) from an edge (69) fixed to the carriage of a circular knife is measured by means of position sensors (80) and is input into the control as part of the positioning distances. The carriage (6) is thereby po-sitioned at a different location such that the cutting edge (19) again lies at the proper location despite the re-grinding.

Abstract: Abstract A trap chamber is formed by a cylindrical container and a head sealed to and closing the upper end of the container, which is releasable from the head by actuating a detent.  Air and entrained liquid from a milk receiver are sucked into the head through a tangential inlet from which air discharges through a top outlet to a vacuum pump while separated liquid spirals down along the chamber wall to a valved drain outlet.  Liquid accumu-lating in the chamber eventually raises a floating ball valve against a seat to close the air outlet and break the vacuum so that the chamber is drained through the bottom outlet.  The ball valve is then released from its seat by an element operable to break the vacuum in the air outlet.  Vacuum in the chamber draws the container upward to compress a sealing gasket against the head and thus prevent leakage.

Abstract: Enhanced Hydrocarbon Recovery by Permeability Modification with Phenolic Gels Abstract Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modifica-tion of the strata of the reservoir with gel-forming phenolic compositions.  The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir.  The per-meability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypachlorite or mineral acid.
