Abstract: ABSTRACT OF THE DISCLOSURE:    The invention is concerned with a corrosion test cell assembly suitable for determining the electrochemical corrosion parameters of metals in corrosive liquid environments, which comprises an electrically non-conductive vessel for receiving an electrolyte solution, an electrically non-conductive cover member adapted to be secured to the vessel, and a plurality of metallic rods supported in the cover member in electrical isolation, both ends of the rods extending axially from the cover member, one end of each rod having terminal connector means thereon and supported within the vessel, the other end of each of the rods being connectable to suitable electrical con-ducting means.  The rods are enclosed in electrically non-con-ductive sleeves extending from the cover member to the terminal connector means; one of the rods is centrally located in the cover member, the remaining rods being arranged symmetrically around the central rod.  A reference electrode is secured to the terminal means of the centrally located rod and is adapted to be supported within an electrolyte solution in the vessel, at least one of the terminal means of one of the remaining rods being adapted to secure a test electrode thereon and supportable within an electrolyte solution in the vessel.  An auxiliary electrode surrounds the reference electrode and the test electrode.  Insulating fluid seals encircle the terminal means and are adapted to be engaged in fluid tight relationship bet-ween the terminal means and electrodes secured thereon.  The electrical conducting means provides circuits with the electrodes during the determination of electrochemical corrosion parameters.

Abstract: Abstract of the Disclosure Method and apparatus is disclosed for extracting and analyzing gas from a body of liquid such as oil in an electrical transformer.  The oil is continuously moved by thermosiphonic action through a conduit in which a gas permeation cell is mounted.  Oil within the conduit is air cooled to create a temperature gradient relative to the body of liquid for establishing the thermosiphonic move-ment.  The permeation cell comprises a semi-permeable mem-brane supported about an elongate porous tube mounted concentric within the conduit so that gas contained within the liquid permeates through the membrane and into a chamber within the cell.  An inert carrier gas is injected into and out of the chamber for carrying the permeating gas to a gas detector-analyzer unit.

Abstract: METHOD OF TREATING FORMATION   TO REMOVE AMMONIUM IONS    F-9332  Abstract of the Disclosure A method of treating a subterranean formation which has undergone an in situ leaching operation which utilized an ammonium carbonate and/or bicarbonate lixiviant.  In such a leach operation, ammonium ions will absorb onto the clay in the formation and will present a threat of contamination to any ground waters that may be present in the formation.  The present method involves flushing the formation with a strong, basic solution, e.g., sodium or calcium hydroxide, to convert the ammonium ions to ammonia which is easily carried from the formation by the basic solution.  After substantially all of the ammonium ions are removed, the formation is then flushed with water to remove any basic solution which may remain in the formation.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus and method wherein speech or other signals are sampled during a time slice of approximately 1/30 second and spectrum analysis is performed on the samples, producing measures of amplitude in several frequency bands with each frequency band being characterized by a binary digit indicating the presence or absence of significant amplitude.  The binary digits are collectively referred to as a sonogram.  Sonograms for several time slices are then concatenated, randomized and decoded using an n-tuple technique to produce a pattern corresponding to the current speech signal.  This pattern is learned by superimposing it on an existing vocabulary entry and is subsequently recog-nized if it is sufficiently similar to one vocabulary entry and different from all others.

Abstract: Improved Valve Moving Push Rod for Internal Combustion Engines and Method of Making the Same Abstract of the Disclosure:     This invention is made with a view to increasing the fusing strength of an end piece in a valve moving push rod for internal combustion engines.  The fusing part of the push rod according to the present invention consists of an .alpha.-martensite structure and a primary truestite structure in a cotransition  boundary range of a segmental section formed into the hardened layer of the end piece from the fused boundary surface of the end piece with a tube end part and is provided with a tough mixed layer arcuated from the inside and part of the above mentioned fused boundary surface to the outside end part thereof.  This mixed layer is obtained by reducing by a heat feeding means a quick temperature drop caused by the fusing part simulta-neously with cutting off the fusing current in welding by electric resistance the end piece on the fixed side surface to the peripheral edge of the end port of a tube material.          Such crack as is recognized in the fusing part of a con-ventional product is not recognized in a product obtained by reducing the quick cooling by this method.
