Title: Alumina-zirconia ceramic
Inventor: BROG TERRENCE K
IPC: C04B35/10
Filed: 1988-07-21
Granted: 1993-06-08
Abstract: ABSTRACT OF THE DISCLOSURE A method for producing a ceramic is disclosed. The method involves comminuting a batch composed of from 6 to 95 percent of particulate ZrO2 and from 5  to 94  percent of particulate Al2O3 . A  part  of  the  particulate ZrO2 is in a metastable tetragonal crystal structure, for  example, as  a consequence of 3m/? of Y2O3 dissolved therein and a part has a monoclinic crystal structure. The comminuted  batch is compacted into a shape, and  the shape  is fired. The degree of comminution of the hatch,  the  firing  conditions  and  the  proportions of stabilized and monoclinic ZrO2 in the batch are controlled to produce a dense, gas  impervious ceramic  which contains both metastable  tetragonal  and  monoclinic  ZrO2,  and  in  such proportions  that  the  ceramic  has  improved   strength  by comparison with an otherwise identical ceramic wherein all of the ZrO2 is in either a metastable tetragonal or a monoclinic crystal structure.    Also disclosed  is a method where the particulate alumina can be an alumina-chromia solid solution containing up  to 50 m/? of chromia.    In  another  embodiment,  a ceramic article is disclosed. The  article  is  composed  of  from  6  to   95  percent  of particulate ZrO2,  from 5 to 94 percent of particulate Al2O3, from 1/4 to 3 3/4 percent of MnO2 and from 1/4 to 3 3/4 percent of TiO2.

Inventor: HEINONEN ROBERT L
IPC: E21B33/08
Filed: 1988-07-22
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE     A wellhead stuffing box for sealing around the polished rod from a pumping unit to a reciprocating well  pump to provide emergency closure of the bore through the wellhead in the event of breakage of the polished rod.   The valve assembly includes a flapper valve mounted on a swivel pin for movement between a vertical open position and a horizontal closed position across the wellhead bore.  The flapper valve is spring biased toward the open position.   A well pressure responsive cylinder and piston assembly is on the side of the wellhead with an operating rod through the wellhead against the flapper valve to move the valve from the open position to a horizontal  closed position.   The piston is exposed to well pressure on the one side urging the piston outwardly to the valve open position and a spring engages the  piston on the  opposite  side  biasing the  piston inwardly toward  the  valve  closed  position when well  pressure  is  not sufficient  to  keep  the  spring  compressed.    One  form of  the wellhead  includes  a  packing  assembly  for  sealing  around  the polished  rod.    A  second  embodiment  includes  only  the  valve assembly which is used with a standard packing assembly.  A third embodiment  of  the wellhead includes  a swivel  mounted packing assembly to permit the polished rod to deviate from the vertical.

Title: Dsrna-based prevention of viral escape
Inventor: CARTER WILLIAM A
IPC: C07H21/00
Filed: 1988-11-17
Granted: 1995-08-15
Abstract: dsRNA reduces the phenomenon of viral escape and cellular damage attendant thereto.  Viral escape is a process by which a virus or intracellular pathogen alters its host range or indirectly alters its susceptibility to antiviral or immunological therapies.  Viruses do so by causing specific changes in their genomic/antigenic composition and/or by causing the elaboration of factors which enhance destructiveness of cells and their ability to multiply progeny virus. Animals susceptible to viral infections and pathology secondary to antigenic drift may have damage reduced by exposing them to dsRNA which prevents or substantially minimizes viral escape brought about through these mechanisms of molecular rearrangement and/or elaboration of factors which break down the natural host defenses.
