Patent NO-178079-C (NO)
Inventor: HRUSCHKA ANTON
IPC: D06L4/70
Filed: 1991-02-06
Abstract: The process comprises three stages, namely an oxygen bleach which is optionally combined with a hydrogen peroxide bleach (EOP stage), an ozone bleach (Z stage) and a peroxide bleach (P stage). According to the invention, the residual oxygen content of the exit air from the Z stage is completely reacted in the EOP stage, and the effluent of the Z stage is used for dilution between the EOP and Z stages and/or for ash removal from the pulp after bleaching. It is advantageous in this case to control the temperature, the NaOH supply and the O2/H2O2 ratio in the EOP stage, so that the oxygen consumption at a constant conversion is adjusted to the residual oxygen content of the exit air from the Z stage.

Title: System for cross-connecting high speed digital sonet signals
Inventor: UPP DANIEL C
IPC: H04L12/66
Filed: 1989-12-08
Granted: 1994-06-07
Abstract: ABSTRACT OF THE DISCLOSURE      A modular, expandable, non-blocking system for cross-connecting high speed digital signals is provided.  The system is capable of connecting DSn, CEPTn, and STSn signals as desired, with lower rate signals being included as components of the high-rate signals or terminating on low speed lines, as desired.  The system accomplishes its goals by converting all incoming signals into a substantially SONET format, and by processing all the signals in that format.  The signals are typically cross-connected in the substantially SONET format, although an expandable non-blocking wide band cross-connect module provided which cross-connects any like signals.  If the outgoing signal is to be in other than SONET format, the substantially SONET formatted signal is reconverted into its outgoing format.  To create a complete system, various modules are utilized, including: add/drop multiplexer means for add/drop applications of DS-0, DS-1, CEPTn signals, etc.; a SONET bus interface; a virtual tributary cross-connect module which cross-connects virtual tributary payloads in space, time, and phase to generate new substantially SONET formatted signals; a wide band cross-connect module; a DS-3/SONET converter; and front end interfaces including a DS-3 line interface, and various STSn interfaces.  The modules may be mixed and matched as desired to accommodate a multitude of applications.

Title: Oxide superconductive wire, method of manufacturing the same and the products using the same
Inventor: HAYASHI NORIKI
IPC: H01B12/06
Filed: 1990-03-29
Granted: 1997-02-25
Abstract: An oxide superconductive wire is provided by, for example, forming an oxide superconductive layer on a tape-type flexible base.  A preliminary compressive strain is applied to the oxide superconductive layer in the longitudinal direction.  The remaining strain can be provided by using a base having thermal expansion coefficient larger than that of the oxide superconductive layer and by cooling the same after heat treatment, due to contraction of the base.  Since the preliminary compressive strain is applied to the oxide superconductive layer, degradation of superconductivity of the oxide superconductive layer can be suppressed even if the oxide superconductive wire is bent in any direction, compared with the wire without such strain.  Therefore, the oxide superconductive wire can be coiled, for example, without much degrading the superconductivity.

Granted: 1996-09-17
Abstract: It is common practice to apply a shrink sleeve to a weld joint in a pipeline. The success of such application depends upon the ability to transport equipment from joint to joint and the adaptability of the heating apparatus to a variety of pipe sizes. A relatively simple apparatus for meeting the above defined requirements includes a skeletal frame carried by rollers for movably supporting the apparatus on a pipe to be heated, a clamp on the frame for releasably engaging the pipe to stabilize the apparatus, and heaters pivotally mounted on the frame for rotation between a closed position around the pipe and an open position permitting movement of the apparatus to another joint. By making the height of the frame variable, the apparatus can be adapted to pipes of different diameters.

Title: Echo canceller
Inventor: YATSUZUKA YOUTARO
IPC: H04B3/23
Filed: 1992-03-11
Granted: 1996-11-12
Abstract: In an echo canceller used in a four-wire digital telephone circuit, a main echo estimator (21) and a sub echo estimator (22) are coupled with a receive path for measuring a receive signal, and subtracters (25, 26) are inserted in a transmit path for cancelling an echo component in a transmit signal. Filter coefficients in said estimators (21, 22) are adaptively controlled by a convergence control processor (24). The main echo estimator has a small step gain for updating filter coefficients so that the response to an echo is slow, while the sub echo estimator (22) has a large step gain and quick response for an echo. An register accumulator (23) is provided so that the filter coefficients by the sub echo estimator (22) are selectively accumulated on the related filter coefficients in the main echo estimator (21) according to operation modes, ordinary mode, accumulating mode, and reset mode. In an ordinary mode, said two echo estimators (21, 22) operate independently from each other, updating the filter coefficients. In an accumulating mode, when an echo output of the second subtracter (26) is lower than that of the first subtracter(25), and the filter coefficients in the sub echo estimator (22) converge, the filter coefficients in the sub echo estimator (22) are accumulated on the related ones in the main echo estimator (21), respectively, and after reset of the coefficients in the sub echo estimator (22), the mode is then switched to the ordinary mode. When the filter coefficients in the sub echo estimator (22) diverge, or echo output of the second subtracter (26) is larger than that of the first subtracter (25), the sub echo estimator (22) is reset, and then, the mode is switched to the ordinary mode.
