Abstract: ABSTRACT            STRUCTURES FABRICATED FROM ALUMINIUM COMPONENTS AND          PROCESSES INVOLVED IN MAKING THESE STRUCTURES            Aluminium alloy components are coated with adhesive and spot-welded  together,  but  are  pre-treated  to  form  a surface  layer  containing  at  least  5%  by  weight  of chromium.      Conversion    coating     and     "no-rinse" pre-treatments   are   described.    Enviromentally   stable structural adhesive bonds are formed.   The pre-treatment can  be  performed  more  rapidly  than  in  prior  art structures.  The components can be formed from aluminium sheet  which  has  been  pre-treated  and  then  preferably coated with press-lubricant.  Such sheet can be stored for up to 6 months prior to forming.

Abstract: ABSTRACT          Polymer-Modified Polyols Polymer-modified polyols of reduced viscosity are made by reacting an organic polyisocyanate with a low molecular weight hydroxyl-containing compound in a polyol in the presence of a specified dispersant.  The dispersant, which is of a type known for dispersing pigments in paints, is obtained by reacting (1) a copolymer comprising units derived from the following ethylenically unsaturated monomers in the stated proportions by weight based on the total weight of the copolymer: (a) 0-50% of a hydroxy group-containing monomer, and/or (b) 0.20% of an amide group-containing monomer, provided that there is always present at least 5% of (a) and (b); (c) 20-80% of a monomer free from carboxyl groups and containing a straight or branched chain alkyl group of from 7 to 22 carbon atoms, and (d) 0-50% of one or more monomers free from the hydroxy, amide and C7-22 alkyl groups present in (a), (b) or (c), and also, as an essential constituent, (e) up to 20% of a monomer containing an epoxide group, the total of monomers (a), (b), (c), (d) and (e) being 100%, with (2) a compound bearing a carboxyl group and a group having pigment dispersant characteristics.          Preferably, it is a copolymer of styrene; 2-ethyl hexyl acrylate; hydroxy isopropylmethacrylate; methacrylamide; glycidyl methacrylate in the ratios 26:40:25:5:4, modified by esterification with p-aminobenzoic acid in the presence of dimethyl dodecyl tertiary amine.  The modified polyols of particular interest are those used in the manufacture of flexible foam slabstock.

Abstract: ABSTRACT      The specification describes a method and apparatus for processing bivalve shellfish, particularly scallops.          The two shells are first parted by a small amount and a cutting tool is inserted to detach the shellfish from one of the shells.  The two shells are then separated.  The shell having the shellfish attached is rotated about an axis passing through the centre of the edible portion and the offal is cut or blown away from the edible portion and is thrown centrifugally away.  The edible portion is then recovered.                             -1a-

Abstract: INTEGRATED CIRCUIT HAVING DISLOCATION FREE SUBSTRATE                 ABSTRACT An integrated circuit bulk substrate having a zinc blende or Wurtzite crystalline structure is alloyed with a material having atoms that replace atoms of the host semiconductor.  The alloyed atoms have a bond length with the nearest neighboring host atoms that is less than the bond length of the host atoms.  The number of bonded alloyed atoms is small compared to the number of host atoms to as not to substantially affect electronic conduction properties of the host material, but is large enough to virtually eliminate dislocations over a large surface area and volume of the host material on which active semiconductor devices are located.

Abstract: ABSTRACT OF THE DISCLOSURE            Differential phase-shifter operating in a wide frequency  band,  with  constant  differential  phase shifting.  This device is characterized by the fact that it  produces  a  differential  phase  shift  between  two perpendicular  polarizations,  with  constant frequency.          This way,  differential phase shifters with the desired flatness in the band can be obtained,  either of 180°          (polarizers for systems of linear polarization) or of 90°          (polarizer for transforming the circular polarization into linear polarization and vice versa).  Such a phase shifter can be used generally in antenna systems.

Abstract: ABSTRACT       The laminated stator body of a large turbo-generator consists of a stack of laminations comprising laminated compression plates, which stack is clamped together by means of tie plates and tension bolts.  The end face of the compres-sion plate is stepped in the axial and radial direction.  The tie plates have either a contour which matches the outside contour of the compression plate or are smooth and, in the latter case, are supported by arch pressure in the radial direction.  The elaborate machining of the compression plate end face, resulting in the elimination of lamination shorts, can thus be omitted without impairing the electrical and magnetic effects of the laminated compression plate on the end field of the machine.

Abstract: METHOD AND APPARATUS FOR  AUTOMATICALLY PRODUCING REPRESENTATIONS   OF THREE-DIMENSIONAL HORIZONS FROM PROCESSED SEISMIC DATA            ABSTRACT Of THE DISCLOSURE    An electronic system  automatically produces representations of   three-dimensional   recommended   horizons  (50a-50e)  from processed seismic  data (40),Significant events, in  the form of turnings,  are identified  in all  of the  digitized traces that make up the processed seismic data.  Pairs of significant events in adjacent traces are determined.   The system determines these pairs through a mutual nearest neighbor technique, together with a  technique for  detecting similar  signs.  The system measures the  curvature  of  the  path  formed  by the paired turnings in successive  digital traces and terminates  the path at any point where the  curvature exceeds a predetermined  limit.  The system then  looks for  three-dimensional continuity  by looking  for a closed loop  of at least  four turnings making  up four pairs of turnings.    These  techniques   yield  at   least  one  horizon represented     in    a    first    format.    The   recommended horizon   (50a-50e),   represented   in   a  second  format.  is essentially  extracted  by   the  system  through   a  recursive "walking"  procedure for identifying all  of the turnings in the recommended horizon and designating those turnings in the second format.  At the  same time, vertical  uniqueness of each  of the turnings  in  the  recommended  horizon  is  examined  and  if a subsequent turning is found to be on the same digital trace as a prior detected turning, the subsequent turning is not permitted. The  second  format  is  used  for  storage  of  the horizon and subsequent display.

Abstract: CUTOFF POLARIZER AND METHOD Abstract of the Disclosure The cladding and a portion of the core of apparatus of a length of optical fiber are removed to form an interaction region where the fiber will not guide a light wave. A metal thin layer placed on the exposed core and a portion of the cladding. Polarizations perpendicular to the metal film couple into the metal film to form a surface surface plasma wave that propagates parallel to the fiber while parallel polarizations radiate through the metal film. The surface plasma wave couples energy back into the fiber so that the throughput of the polarizer is only the perpendicular polarization component. A photodetector forms an error signal from the polarization radiated from the fiber, and control circuitry processes the error signal to drive a polarization controller that adjusts the polarization of light input to the polarizer to minimize the error signal and maximize the intensity of the desired polarization output from the polarizer.
