Abstract: L'invention concerne un circuit (58) destiné à compenser des variables dans un transducteur (2). Dans ledit transducteur, un capteur (54) détecte une première variable de processus telle qu'une pression différentielle et un convertisseur (56) numérise la variable de processus détectée. Le capteur (54) détecte des pressions comprises dans une plage de valeur de pression. Une mémoire (68), située dans le transducteur, mémorise au moins deux fonctions d'appartenance. Cette mémoire (68) mémorise également un ensemble de formules de compensation, chaque formule correspondant à une fonction d'appartenance. Un circuit de sélection (64), faisant partie du transducteur (2), sélectionne les fonctions d'appartenance ayant une valeur différente de zéro, pour la variable de processus numérisée, et un circuit de correction (66) délivre au moins une valeur de correction calculée à partir d'une formule de compensation correspondant à une fonction d'appartenance sélectionnée. Un circuit de pondération (70) multiplie chaque valeur de corrrection par sa fonction d'appartenance sélectionnée correspondante, et combine les multiplicandes pour délivrer une variable de procédé compensée. La variable de procédé compensée est couplé à un circuit de commande (6) reliant le transducteur (2) à un système de commande (4).

Title: Synthetic ester lubricant stabilizer composition
Inventor: LAI JOHN T
IPC: H04B7/185
Filed: 1994-12-15
Abstract: An antioxidant stabilizer composition is disclosed that is the reaction product of a diphenylamine and an N-aryl naphthylamine in the presence of an organic peroxide.  The mole ratio of diphenylamine: N-aryl naphthylamine is from 1:1 to 10:1.  This results in more oligomeric reaction products and significantly less unreacted monomeric residual reactants.  The resultant product composition comprises diphenylamine homooligomers and diphenylamine/N-aryl naphthylamine cross oligomers.  The diphenylamine and N-aryl naphthylamine are desirably substituted with alkyl groups having from 1 to 20 carbon atoms or styryl groups.  The reaction temperature is preferably from about 130° to 150°C.  The controlled reaction conditions allow the use of solvents with extractable hydrogen atoms without producing significant amounts of dehydrocondensation between the solvent and the diamines.  The reaction products have superior oxidative resistance in the Oxidation Corrosion Stability Test (OCS) and Vapor Phase Coker Test over products products produced under other conditions.

Title: Alarm monitor for belt slip in a combine
Inventor: SALZ MAURY V
IPC: A01D75/18
Filed: 1996-09-23
Abstract: An agricultural vehicle, tractor, or combine includes a slip monitoring system for determining whether a slip condition exists.  The agricultural vehicle includes a combustion engine which indirectly drives a piece of equipment such as a rotor.  The rotor is mechanically coupled to the engine via a rotor-drive belt system including two belts and four pulleys.  The slip monitoring system analyzes the speed of the rotor and the speed of the engine to determine if there is slippage between the belts and the pulleys.  The system determines when a slip condition exists by comparing the ratio of the rotor speed to the engine speed to the ratio of the rotor speed to the engine speed under no-load conditions. When the system determines that the ratio is below the threshold, a display provides visual and audio warnings of the slip condition.  The monitoring system is implemented as a software subroutine.

Title: Synthetic swelling clay minerals
Inventor: VOGELS ROLAND JACOBUS MARTINUS
IPC: C08F4/02
Filed: 1995-08-31
Abstract: Swelling clay minerals are made up of elementary three-layer platelets consisting of a central layer of octahedrally oxygen-surrounded metal ions (octohedron layer), which layer is surrounded by two tetrahedrally surrounded, silicon atom-containing layers (tetrahedron layers), a number of such elementary platelets being optionally stacked. The dimensions of the clay platelets vary from 0.01 µm to 1 µm, the number of the stacked elementary three-layer platelets varies from on average one platelet to twenty platelets, while in the octahedron layer at most 30 at.% of the metal ions has been replaced by ions of a lower valency and in the tetrahedron layers at most 15 at.% of the silicon ions has been replaced by ions of a lower valency, such a replacement having taken place in at least one of these layers and these layers having a deficiency of positive charge because of the replacement. They are prepared by bringing the pH of an aqueous liquid containing the components of the clay to a value of 3-9 and the temperature of the liquid to a value of from 60 to 350 °C and maintaining it at said value for the time required for the reaction, the pH being maintained at a value within said range.
Patent CA-2199122-A1 (CA)
Inventor: CAMACHO JUAREZ FRANCISCO
IPC: C09C3/04
Filed: 1995-12-07
Abstract: The process is carried out by using pigments which contain conventional metal elements treated by a chromatic stabilization method, in screenings of at least one polymer to be coloured, prior to the introduction of the polymer mass into an extrusion pre-chamber. The stabilization method consists in modifying the distribution of electrons in the external orbitals of the pigments so as to present an affinity to electron distribution characteristics in the external orbitals of the polymer to be coloured, through photonic discharges of ultrashort wave length light onto the pigments in order to displace electrons from the internal orbitals to the external orbitals of the metal elements in the pigments, in a number inversely proportional to the value of the molecular weight to be obtained. The energy applied to the photonic discharges is determined as a function of the difference of the power potentials between said orbitals. To this effect, the wave length (X) of the ultrashort wave length light applied, is adjusted by dividing the light velocity (C) by the Planck constant (KP), and substracting from the result a power potential higher than the power potential of said internal orbitals. The discharges are applied during a time duration which provide for the exposure of pigments during 0,1 second per 10 microns of thickness of the pigments to be treated.

Filed: 1995-09-26
Abstract: Two rolls (34, 36) are mounted to a frame (30) and rotated about spaced parallel axes (62) by electric motors (56) operating through speed reducers (58). Each roll (34, 36) has a surface (40, 42) formed of uniformly spaced, circumferential extending triangular grooves (44) and ridges (46) defined between grooves (44). The ridges (46) of one roll (34, 36) are closely spaced from the grooves (44) of the other roll (34, 36) to define a sinuous nip (32) therebetween.
