Title: Composite center electrode for a spark plug and method of producing same
Inventor: CLARK RONNIE W
IPC: H01T13/39
Filed: 1986-02-19
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to a composite spark plug center electrode having a sparking tip composed of a precious or semi-precious metal and a method for producing same is disclosed.  A right circular cylindrical billet of a corrosion-resistant material is initially formed into a cylindrical cup having an opened end and a closed end.  A small conical recess may be formed in the center of the exterior of the closed end during the formation.  A hole is next formed in the closed end of the cup.  A right circular cylindrical billet of a high thermal conductivity material is next inserted within the opened end of the cup and pressed to fit tightly against the sidewall and bottom of the cup cavity to form a composite billet.  An insert formed of a precious or semi-precious metal is then inserted within the hole and pressed to fit tightly therein.  The opened end of the cup is formed inwardly to partially encase the billet therein.  The composite billet and precious metal insert are inserted within a close-fitting bore of a die having an extrusion orifice.  A plunger is inserted within the bore of the die against the filled end of the composite billet to extrude all but a terminal portion of the composite billet, adjacent the filled end thereof, through the extrusion orifice to form center electrode blank.  The opposite end of the center electrode blank containing the precious metal insert is extruded a second time to form a reduced diameter portion. Lastly, the opposite end of the center electrode blank is ground to provide a flat end surface, while the terminal end thereof is ground to provide a precise longitudinal dimension of the center electrode blank.

Inventor: MORGANTI VICTOR M
IPC: G06F12/12
Filed: 1987-05-29
Granted: 1991-05-21
Abstract: ABSTRACT         In  a  multiprocessor,  multiprogrammed  data processing   system  employing   virtual  addressing, apparatus and  method  are  provided  for  selecting a page frame in main memory to be replaced  by a new page of logic signal groups required by a processor.          Rather  than  utilize  a  algorithm  implemented  in  a series of logical decisions determined by a software procedure,  the  present  invention  provides  for  a single  instruction  that  uses  the  status  signals included with a page descriptor to address an entry in a  table  of  resulting  status  signals.  The relationship between the status signals and the table entries  implements  the  algorithm.   The  table  with entries  of  resulting  status  signals  is  associated-with the instruction and is stored in the processor when the instruction is prepared for execution by the processor.  The resulting status signals are stored with  the  page  descriptor.  The  resulting  status signals are analysed  by a  software  procedure,  the software procedure implementing the page replacement and  executing  other  activity  indicated  by  the resulting status signals.

Abstract: ABSTRACT OF THE DISCLOSURE     This apparatus is capable of preventing contamination in the interior of an airturbine hand-piece and its drive for use in dental treatment such as cutting a tooth.  The apparatus comprises an airturbine drive air circuit, a discharge air circuit, and a chip air circuit for vaporizing cooled water, which serve as passageways for air at a relatively high pressure when the hand-piece is in operation and which are kept interiorly at a low air pressure when the hand-piece is out of operation.  These passageways and change-over valves therefore are incorporated in a single body.  When the hand-piece is inoperative upon completion of the treatment, it is possible to prevent various germs from penetrating from outside into the interior of the hand-piece.  The apparatus can be reduced in a compact size and can be formed of plastics.

Abstract: APPARATUS AND METHOD FOR CREATING THIN AND THICK PATTERNS                          ABSTRACT  A system for producing thin patterns in wave-energy sensitive media of planar form as well as articles of multiple thicknesses and multiple patterns in wave-energy sensitive media of fluidized form, said media thicknesses of constant or varying characteristics. In transposing the general principles of the present invention into a preferred embodiment thereof, which is presented by way of example and not by way of limitation, an energy beam generator is displaced in a continuous fashion along a single axis in a plane adjacent to an energy sensitive medium upon which a pattern or image is to be exposed. In the case where a single photographic film or thickness of wave-energy sensitive media is to be exposed, a single one-direction passage of the energy beam generator suffices to transfer the entire desired single image or pattern to the film or media, which may then serve as a masking tool or other appropriate purpose. The exposure of several adjacent thicknesses of wave-energy sensitive media yields a thick pattern, the use for which may be as a model of a part which would otherwise require several processes in order to be fabricated. Existing means of creating such products do not combine the capacity of producing both thick and thin patterns.
