Title: Sealing assembly for subterranean well packing unit
Inventor: STONE PATRICK C
IPC: E21B33/12
Filed: 1990-08-30
Granted: 2001-05-29
Abstract: In subterranean wells, it is common to effect the radial expansion of an annular organic sealing element into sealing engagement between a tubular inner body and the inner wall of a well conduit, such as a well casing. Extrusion of the organic material has been encountered between the inner surface of upper and lower cone elements and the exterior of a tubular body portion and also between the inclined surfaces of upper and lower cone elements and the cooperating surfaces of cone rings. The first mentioned extrusion path is eliminated by forming a generally radial surface on the inner end of the upper and lower cones and inserting a carbon fiber filled organic material in the resulting annular chamber. The extrusion path between rhe inclined surface of the cone and the cooperating surface of the cone ring is minimized by utilizing the forces exerted by the compressed sealing material of the packing element to effect the shearing of the vertex portion of a packer ring along a plane that corresponds exactly to the inclined surface of the cone rang.
Patent CA-2030302-C (CA)
Title: Apparatus and method for determining elastic properties of optical fiber by contact area measurement
Inventor: ROCHESTER JAMES
IPC: G01N3/00
Filed: 1990-11-20
Granted: 1995-07-04
Abstract: The  elastic  properties  of  an optical fiber (10)  are determined from measurements of the contact area  (20,  24)  of  the optical fiber (10) against a surface  (16,  22),  under a loading perpendicular to the  surface.   In  a preferred approach, an optical fiber  is  passed  over  a  curved  surface (22) of a transparent  lens  in the form of a pulley (38), with a  tension  applied  to  the optical fiber (10).  The buffer  layer  (14)  of  the  optical fiber  (10) is flattened  against  the  curved contact surface (22), forming   a   contact   region  (24)  whose  area  is measurable.    The  relative elastic deformability of the  buffer  layer  (14),  a  function of its elastic modulus,  is  determined  from  the  contact area and other    measurable   parameters.     Contact   area measurement  is performed continuously as the optical fiber  (10)  is  passed  over  the  pulley  (38)  by monitoring  the  amount  of light that is transmitted through  the  contact region (24).  The variations in the elastic properties of the optical fiber (10) may therefore  be  measured  continuously  as the optical fiber (10) is transported over the pulley (38).

Title: Vacuum-suction degassing apparatus
Inventor: SANO MASAMICHI
IPC: C22B9/04
Filed: 1991-06-17
Granted: 1999-08-03
Abstract: A melt is stored in a vessel.  A lower half of a degassing member is immersed in the melt.  The degassing member has a cylindrical form with the lower end closed, and the lower half section is made of a porous material which is permeable to gas and impermeable to melts as molten metal, molten slag, or molten matte.  This lower half section is a partitioning member.  When an internal space inside the degassing member is sucked to realize vacuum or reduced pressure atmosphere, gas producing components in the melt pass through the partition member of the degassing member, and are exhausted to inside the degassing member, thus being separated from the melt.          Also, by making the degassing member rotate or move in a horizontal or vertical direction, the melt is stirred.     With these features, gas-producing components in the melt can be removed at a high efficiency.
