Abstract: SEMICONDUCTOR STRUCTURES AND MANUFACTURING METHODS                 Abstract of the Disclosure A plurality of microwave semiconductor devices is pro-vided by plating a thin heat sink layer on a surface of a wafer of semiconductor material, masking selected portions of the heat sink layer, and plating unmasked portions of the heat sink layer to form a support layer.  Substantial portions of the semiconductor material are removed to form a plurality of mesa shaped diodes, at least one semiconductor mesa shaped diode being formed in each region of the semiconductor material disposed on the masked portions of the heat sink layer.  Thus each mesa shaped diode, or sets of mesa shaped diodes, has formed on one surface thereof a thin heat sink layer while the mesa shaped diodes are supported by the support layer for subsequent processing.  Upper electrodes for the diodes are formed interconnecting the mesa shaped diodes.  The individual diodes, or sets thereof, are then separated from the support structure to provide individual single diode, or multiple diode devices.

Abstract: GOLD RECOVERY PROCESS Abstract of the Disclosure A process for treating refractory ores combines pressure oxidation treatment of the ore with cyanidation and carbon-in-pulp recovery.  Pressure oxidation is carried out under acidic conditions, at elevated temperatures and pressure.  Before cyani-dation, the oxidized slurry is subjected to a multiple stage washing operation to remove excess acid and heavy metals generated during the pressure oxidation.  Such heavy metal removal lowers the subsequent cyanide usage and makes the process more economical.  Cyanidation is carried out in a conventional manner, and it has been found that carbon-in-pulp recovery leads to greatly enhanced recovery of gold when compared to other conventional methods, such as zinc precipitation.

Abstract: PRESSURE SEAL FOR VALVE STEMS AND THE LIKE            ABSTRACT          An improved elastomeric seal is provided for preventing both low or high pressure fluid from escaping past a rotatable valve stem or similar shaft.  The annular seal comprises an outer generally envelope-shaped first plastic member for sealing engagement with the rotatable stem and valve bonnet, and an inner second plastic member substantially encapsulated by the first member.  The annular legs of the envelope-shaped member are positioned downstream from fluid pressure, thereby sealing the inner second member from fluid attack.  Novel techniques are employed for forming the elastomeric seal outside the valve bonnet by applying a substantial radially-directed force for deforming the first plastic member into the envelope configuration, while deforming the inner plastic member into an elliptical configuration.  The seal in the substantially deformed configuration is then assembled within the bonnet cavity while preventing radial expansion of the envelope-shaped member.

Abstract: ABSTRACT OF THE DISCLOSURE         A high pressure reaction vesselhas a container portion and a removable head portion which houses a flow channel or channels, valve members and valve operators, and which seals and covers the container portion.  Each channel terminates at a tapered valve seat angled at at least 36° with respect to the horizontal and each of the valves is provided with a mating tapered surface which is wedged more tightly within the valve seat as pressure within the vessel increases.  A port and a chute are provided for introducing a particulate solid feed through at least one of the channels into the interior of the vessel.  In one embodiment a dip tube depends from a second valve seat (in communication with a second channel) and extends to a point adjacent the bottom of the container portion.  In the preferred embodiments the head portion is surrounded by a removable flange having a central tapered opening and is in the form of a plug member in which the channels are formed and which carries the valve seats, valves and valve operators.  The circumference of the plug member is tapered to mate with the tapered surface of the removable flange in such a way that increasing pressure within the vessel enhances the seal between the plus member and the central opening of the removable flange.  In one embodiment the body portion of the reaction vessel is provided with a liner of a halogenated hydrocarbon resin which extends upward to a seal between the tapered surfaces of the plug member and the central opening of the removable flange and is pinched more tightly therebetween as pressure within the vessel increases.  In another embodiment the liner is tubular and similar removable flanges, with mating plug members, are provided at top and bottom of the container with a wedged valve and valve seat providing for solids discharge through the bottom plug member.

Abstract: METHOD AND SYSTEM FOR GRAPH IMAGE STORAGE AND RETRIEVAL   ABSTRACT OF THE DISCLOSURE    Automation  of  graph image storage and retrieval in  a multi-user system having a central processing facility  with performing  processes  that create and  translate  graphical image   representations   in varying  levels  of   readable expression.   The  created,  translated representations  are stored  in system storage in the form of graph image  files. The  invention  is expressed as a  method  that  tabularizes stored  graph image representations by table  entries,  each identifying  a specific graph and including a listing of the corresponding graph image files.   When a user of the system identifies  a graph by table entry and specifies  a  machine output  or  modification  function to be  performed  on  the identified  graph,  the tabularized entries are searched  to locate an entry for the identified graph.   Once the correct table  entry  is found,  the graph file listing is  searched according  to  a user-specified  representation  preference ordering  to determine whether a specified  output  function can  be  performed  by any of the stored graph  image  files produced  for  the identified graph.   If a match  is found between one of the representations stored for the graph  and one  of the representations in the preference ordering,  the matched file is retrieved from storage and translated to the level  required for the function.   The translated  file  is then dispatched to the user for performance of the function.

Abstract: CANISTER HEATER WITH PTC WAFER                     Abstract An electric heater assemblage for attachment to the air intake opening of a fuel vapor recovery canister of the type containing material adapted to alternately ad-sorb and store, or release fuel vapor. The assemblage includes a wafer of electric resistance heating materi-al, and electrical connections for effecting energiza-tion of the wafer. The wafer has opposite expansive surfaces, and there is a first wall located at one side of the wafer and having an expansive surface coextensive with one wafer surface, and a second wall located at the opposite side of the wafer and having an expansive sur-face coextensive with the other wafer surface. The first wall and wafer thus define a first chamber, and the sec-ond wall and wafer define a second chamber in communica-tion with the first chamber at the periphery of the wa-fer. A housing that carries the wafers and walls directs air from the exterior of the canister into the first chamber, past one side of the wafer and its periphery and into the second chamber, past the opposite side of the wafer and thereafter to the interior of the canis-ter, for imparting heat to the adsorbent material con-tained therein. The advantage of the present construc-tion over the devices of the prior art is that improved efficiency is obtainable, while maintaining low overall cost.
