Title: Method and apparatus for providing instructions for the production of structured values
Inventor: GARCIA JOSE M
IPC: G06F9/06
Filed: 1990-12-19
Abstract: METHOD AND APPARATUS FOR PROVIDING INSTRUCTIONS FOR THE                PRODUCTION OF STRUCTURED VALUES Abstract Instructions for producing a structured destination value are provided by applying a rule application specifier to one or more typed source values. The rule application specifier refers to a production rule which specifies how any destination value having the type of the destination value is produced from any source values having the types of the source value. The rule application specifier includes a first part indicating what components of the source values are to be used to produce the destination value and a second part indicating how those components are to be used to produce the destination value. The first and second parts include structure specifiers specifying the structure of any structured types and component names which refer to the components of the source value which are used in the destination value. The component names may refer to components of possibly nested lists. Components from less than all of the elements of a list may be specified, as well as the order in which the components will be used. The second part may include a possibly recursive reference to a production rule which is applied to components represented by component names to produce a component of the destination value. Production rules may also have multiple rule bodies. Which rule body is applied is determined by the values of components of the source values. The instructions are provided by an interpreter which interprets parse trees made by a tree builder from source text containing source code for the types of the values, the production rule, and the rule application. Binding of type information and values to the component names is accomplished by annotating the parse tree representing the production rule.

Abstract: Method and apparatus for automatically loading at least one look-up table in a textile dyeing system with firing time data. The machine operator enters a list of entries including a base entry, machine color loading entries and a stock entry into the system. A firing time table of firing times is generated for each of a plurality of color bars with respect to a given base, from the base entry. A machine color table of color data is generated for each of the plurality of color bars from the machine color loading entries and a pattern color table of pixel codes and their associated colors with respect to a given pattern is generated from the stock entry. The system correlates the firing times, color data and pixel codes to obtain a modified firing time for each pixel code for each color bar and loads the look-up table with the modified firing time data. <IMAGE>

Title: Method for measuring the fibre orientation anisotropy in a fibrous structure
Inventor: BERNARD PIERRE
IPC: G01N21/21
Filed: 1991-09-20
Abstract: ABSTRACT         A  method  and  a  device  for  the  non  destructive measurement of the fibre orientation anisotropy in a fibrous structure. The method relies on the difference of refractive indices  for  light  beams polarized  in  two  perpendicular directions to measure the value of the anisotropy on the surface of a fibrous structure. Because the use of an infrared light, with a wavelength in the 9 to 11 µm spectral range, the penetration depth of the light is of the order of a few tenths of  microns  and  the  fibrous  structure  shows  a  large birefringence directly associated with the fibre orientation anisotropy. This birefringence can be measured as a difference in the refractive indices of the fibrous structure in two different directions. A light beam produced with an infrared light source, such as a CO2 laser, is modulated by a chopper, linearly polarized and sent to a photoelastic modulator which varies the state of polarization of the light at a given frequency. After directing the modulated light towards the surface of the fibrous structure, the light is reflected and polarized again. The intensity of the second harmonic and the total intensity of the reflected polarized beam is measured according to a plurality of angles of incidence. These angles are obtained by the rotation of the sample platform parallel to the plane of incidence. The angles of incidence at the minimum ratio between the intensity of the second harmonic and the total intensity (Brewster's angle) are calculated for two different orientations and the fibre orientation anisotropy is determined by subtracting the two Brewster's angles: the higher is the difference between the Brewster's angles, the higher is the fibre orientation anisotropy. The average refractive index is obtained from the mean value between the Brewster's angles.

As the vessel rotates around the mooring device the flexible pipes are twisted around the central rigid pipe forming a helix.  An axial swivel is provided in each flexible pipe to relieve torsion in the flexible pipe.
