Abstract: ABSTRACT OF THE DISCLOSURE     The present invention teaches a method of planarizing built-up vacuum deposited surfaces or areas on Josephson junction and semiconductor devices so that successively deposited layers do not replicate the undulations of previous layers.  After a surface layer is deposited in a vacuum system and part of the surface is etched, a raised surface is generated.          A photoresist lift-off stencil is applied to the surface to be preserved and the material to be removed is removed by isotropically etching so as to leave an overhang or ledge of photoresist material over the area of the material retained.          A new layer of material is now deposited by vacuum deposition so as to almost fil the area to be planarized.  A small gap remains between the top of the new material being vacuum de-posited and the bottom of the photoresist stencil so that solvent can be introduced to the stencil.  When the photoresist stencil is removed, the top of surface being preserved is substantially planar with the new layer of material.

Abstract: ABSTRACT    This invention relates to packer element design for use in well bores that may be at a relatively low initial temperature and be subsequently heated to much higher temperatures.  High temperature packing material of asbes-tos fibers impregnated with Inconel wire is employed in packer rings of frusto-conical shape which face on a center packer ring of triangular cross-section formed of the same material.  Low melting point thermoplastic wafers of frusto-conical shape are interspersed at least between adjacent frusto-conical packer rings.  These thermoplastic wafers soften at a relatively low well bore temperature and help to initiate a seal when squeezed between the high temperature rings as the packer is set.  As the well bore temperature increases, the low melting point thermoplastic liquifies and is squeezed out from between the high temperature packer segments, which then take over the sealing function.

Abstract: P A T E N T            IMPROVEMENTS IN OR RELATING TO METHOD OF PREPARING POLYMER LATTICES OF HOMOGENEOUS INTERPENETRATED STRUCTURE.          INVENTION : ALBERT GOURDENNE             PASCAL HEINTZ            ELECTRICITE DE FRANCE (SERVICE NATIONAL) ABSTRACT         A method of preparing polymer lattices of homogeneous interpenetrated structure, starting from a mixture of at least two basic prepolymer constituents is characterised by the fact that a microwave radiation is applied having a frequency spectrum chosen in order that it interacts preferentially with the first prepolymer and a power density chosen in order that it directly activates the exothermic reaction of cross-linking of the first pre-polymer.  The cross-linking of the second prepolymer is only triggered under the combined action of the heat due to the interaction of the microwave energy with the second prepolymer and the heat introduced by the cross-linking reaction of the first prepolymer, which makes it possible to combine propagation of the two cross-linking reactions at similar speeds.

Abstract: ABSTRACT        This  disclosure  is  directed  to  a  method  of obtaining coated glass articles having a desired shading coefficient with the most economical thickness of coating composition  applied   thereto.    The  method   taught   is characterized  by  the  following  steps.   A  plurality  of glass   samples   are   coated   with   a  selected   coating composition.   This  coating  operation  is  carried on  the various  glass  samples  in  a manner  such  that  the  glass samples have different coating thicknesses of the selected coating  composition.    The thickness  of   the  coating composition on each glass sample, along with the resulting shading coefficient, is measured.  The correlation is made between the thickness of coating and the resulting shading coefficient.  The correlation is one which will define two separate  functions  interconnected by a transition point.          A  first  function  (1)  is  one  in  which  the  shading coefficient decreases with  increasing coating  thickness.          A  second  function (2)  is  one  in  which  the  shading coefficient  remains  relatively  constant  although  the coating  thickness  is  increasing.   The  method  of  this disclosure  is concluded by coating commercial  quantities of  glass  with  the  selected  coating  composition  to  a thickness  which  is  plus  or  minus  10%  of  the  coating thickness  where  the  correlated  relationship between  the coating thickness and the shading coefficient goes through its transition point (3) from the first defined functional relationship   (1)   to   the   second   defined   functional relationship (2).
