Abstract: ABSTRACT        Electrode arrangement for electrochemical cells. A deformable sandwich structure (working electrode, insula-tor, secondary electrode, insulator) forms a primary electrode arrangement. A three-dimensional structure can be formed by rolling up the primary sandwich structure around and axis. The shapes and material structures of electrodes and insulators co-operate with each other to enable axial and/or radial flow of an electrolyte which is pumped througth the electrode roll. With such electrode rolls a high ratio of electrode surface to cell volume can be attained. Furthermore, by mounting one or more of the electrode rolls on a hollow axle and pumping the electrolyte through orifices of the axle from its interior into the electrode rolls, the scale-up of current and voltage of a cell is considerably facilitated and advantageously achieved.

Abstract: ABSTRACT OF THE INVENTION      Disclosed is an adaptive filter for suppressing interfering narrow-band signals in a composite signal con-taining a desired broad-band signal.  The adaptive filter is useful in a system which uses a broad-band signal and signal processing apparatus to derive information from the broad-band signal.  In one embodiment the system makes use of a delay line to provide a delayed replica of the composite signal which is used to provide a correction signal to cancel the interfering narrow-band signal.  The desired broad-band signal is not canceled by the adaptive filter.

Abstract: DIRECTIONAL OPTICAL WAVEGUIDE COUPLERS     Abstract of the Disclosure Directional optical waveguide couplers for use with planar-form optical waveguides or optical fiber waveguides are disclosed.  In the coupler arrangements, light energy propagating in a direction of interest in the core of a cladded optical waveguide is first coupled into a selected region of the cladding by a mode coupling means and then coupled out of the selected cladding region by a branching optical waveguide or power tap for subsequent conversion to a representative electrical signal.          The selected region of the cladding is isolated from spurious cladding modes by a pair of stripper-absorber means to ensure that the coupled out light energy is derived only from the core-guided modes propagating in the direction of interest.

Abstract: Abstract of the Invention A well jar has telescoping inner and outer elements having a torque transmitting connection therebetween.  An intermediate member is rotatably mounted relative to the telescoping elements and is affixed in a longitudinal direction to one of the teles-coping elements.  A releasable latch is connected between the intermediate member and one of the telescoping elements.  The intermediate member is rotatable relative to the telescoping elements upon a predetermined minimum longitudinal force applied between the telescoping elements.  The rotation causes a release of the latch and movement of the telescoping elements to an impact of coacting impact faces on the telescoping elements. An improve-ment involves a time delay section connected between the intermed-iate member and at least one of the telescoping elements for restraining such relative rotation for a preselected time interval of application of at least such minimum longitudinal force.  In addition the preferred embodiment has the time delay section and the latch located in a common chamber, and the time delay section includes a hydraulic time delay device that makes use of the same fluid as that used for lubricating the latch.  A method is disclosed for filling the common chamber and a method is dis-closed for forming a well jar having such a fluid chamber.

Abstract: Abstract of the Disclosure:              A pressure accumulator and method of forming the same is disclosed which comprises the steps of advancing a cylindrical resilient metallic sleeve carrying a separator or bladder through the open mouth of a shell forming a part of the casing of the accumulator, the shell including on an inner wall surface thereof an annular groove defining an inwardly directed sharpened lip in the casing wall.  The sleeve is positioned such that the outer circumference thereof, adjacent its upper end, is disposed in abutting relation to the said lip.  An electrode is placed against the upper edge of the sleeve opposite the lip at a posi-tion remote from the deformable bladder.  The shell section and the electrode are relatively rotated about an axis of revolution coincident with the longitudinal axis of the shell while electrical current is passed through the electrode, sleeve, and into the casing, the current flow being sufficient to induce a melting and consequent fusion between components of the metal forming the sleeve and lip portion, whereby the sleeve is secured to the shell section and a seal is defined by the annular fused por-tions of the shell and the sleeve.  Thereafter the open mouth portions of the shells are welded together to define a completed casing.
