Abstract: METHOD FOR FILLING ELECTROCHEMICAL CELLS AND ARTICLE     ABSTRACT   A method for filling an electrochemical cell can with a pressurized liquid electrolyte solvent and/or a liquid depolarizer.  The method includes disposing an electrochemical cell system within a cell can having an open end, loosely positioning means for temporarily sealing the cell can between the open end of the cell can and the electrochemical cell system, and redu-cing the diameter of the open end of the cell can thereby confining the temporary sealing means between the electrochemical cell system and the open end of the cell can.  The pressurized liquid electrolyte solvent and/or liquid depolarizer is introduced into the cell can.  After the cell can is filled some of the electrolyte solvent and/or liquid depolarizer vaporizes. The resulting gas forces the temporary sealing means into temporary sealing engagement with the narrowed end of the cell can thereby substantially pre-venting loss of electrolyte solvent and/or liquid depolarizer from the cell can before the cell can is capped and permanently sealed.

Abstract: ELECTROSURGICAL GENERATOR     ABSTRACT OF THE DISCLOSURE            A solid-state electrosurgical generator is disclosed which provides three separate output circuits that may be operated from a single common power source.  One of the output circuits produces an output electrical waveform which is optimized for cutting and coagulation with monopolar electrodes.  Another source provides a waveform which is optimized for cutting and coagulation with bipolar electrodes.  The other electrosurgical source produces an output electrical waveform which is optimized for fulguration.  The output circuits produce the optimized waveforms by appropriately processing electrical power provided by a D.C. power source.  In order to do this, the output circuits may be connected to the power source by means of four semiconductor switches which may be arranged in either a bridge configuration for one output circuit or in a series arrangement for the other output circuit.  The switches are, in turn, controlled by a timing circuit which provides different timing waveforms to the switches depending on their configuration.

Abstract: ABSTRACT OF THE DISCLOSURE     Process and apparatus for measuring the effective diameter of the guided mode in a monomode optical fibre.     The apparatus comprises, for example, a lighting source such as a tungsten filament, quartz-halogen lamp, a monochromator for selecting light of wave-length .lambda. from the lamp, as well as a variable aperture lens.  The image of the source is performed on the input face of the fibre by means of the lens, said image having a size greater than the diameter of the fibre core.  The light from the source falls on the fibre in accordance with a cone having an apex halfangle 0.  The lighting power P(0) transmitted by the fibre is measured as a function of 0 and the effective diameter 2wo is determined by the formula P(0) = P? [1 - exp (-2( 2wo2/ 2) sin2 0)]   in which P? is independent of 0.     Application to the characterization of monomode fibres.            (Fig. 1)

Abstract: VERTICAL CHANNEL FIELD CONTROLLED  DEVICE EMPLOYING A RECESSED GATE  STRUCTURE AND METHODS OF MAKING     ABSTRACT OR THE DISCLOSURE          A vertical channel junction gate electric field con-trolled device (e.g., a field effect transistor or a field con-trolled thyristor) includes a semiconductor base region layer, and a plurality of grooves having vertical walls formed in the upper surface of the base region layer.  Between the grooves on the upper surface of the base region layer but not extending to the grooves are upper electrode regions, for example, source electrode regions or cathode electrode regions. Formed in the groove bottoms and sidewalls are junction gate regions.  Upper electrode terminal metallization is evaporated generally on the upper device layer, and gate terminal metallization is over the junction gate regions at the bottoms of the grooves.  The disclosed structure thus has continuous metallization along the recessed gate regions for a low-resistance gate connection.  The structure facilitates fabrica-tion by methods, also diclosed, which avoid any critical photo-lithographic alignment steps in masking to define the locations of the source (or cathode) and gate regions, and avoid the need for any mask or mask alignment for metal definition when forming elec-trode metallization.  As a result of the structure of the upper electrode and gate regions, it is not critical to avoid any metal deposition on the groove sidewalls.

Abstract: ABSTRACT An improvement in a condensing furnace where gaseous products of combustion are ducted through fin tube condensers that act to heat incoming  air.  The improvement involves spraying water into the products of combustion upstream of the fin tube consider, so that the sprayed water droplets mix intimately with the products of combustion and are thus vapourized.  In this manner, the combined water vapour and gaseous combustion products can condense in the fin tube condenser to create a liquid condensate of which the pH is closer to neutral than would have been the case in the absence of the sprayed water.

Abstract: ABSTRACT          This invention relates to an imaging composition for providing improvement in speed of image formation and quality of the image.         Dark images or visibly colored images can be formed on various substrates without the use of carbon by methods which provide for the reaction of rosin soaps of nickel or iron with dye precursor metal chelating materials such as dithiooxamide chelating agents.  These chelating agents operate to form colored complexes with the nickel or iron cations.         A shortcoming of systems containing rosin soaps of nickel is the length of time required for an intense image to form after the reaction of nickel with dithiooxamide. Users of carbonless imaging systems generally prefer that such an image be formed in a shorter time.         This invention provides a soap composition which comprises (1) at least one metal cation, e.g. nickel, which produces an image when reacted with a dye precursor which is a derivative of dithiooxamide, (2) at least one rosin soap, and (3) at least one metallic soap e.g. lithium stearate.  The presence of the metallic soap results in a higher level of metal cation, i.e., nickel or iron, available for image formation, thus improving speed of image formation and image quality.
