Abstract: A magnetic field sensor is provided in which plane polarised light at first and second wavelengths is admitted into a block (2) of material exhibiting the Faraday effect. The light undergoes rotation of its plane of polarisation in the presence of a magnetic field. The angle of rotation of the plane of polarisation is proportional to the strength of the magnetic field, and is a function of wavelength of the light. The light emerging from the block (2) is analysed to determine the amount of rotation experienced by each wavelength. Inclusion of an output polariser (24) results in a sensor in which the light leaving the sensor is colour encoded as a function of magnetic field.

Abstract: L'une des préoccupations majeures concernant l'éradication globale des virus poliomyélitiques se rapporte à l'aptitude à détecter rapidement des virus poliomyélitiques de phénotype sauvage dans des échantillons cliniques. L'invention se rapporte à un procédé de détection des virus poliomyélitiques appartenant à tous les trois sérotypes dans des isolats viraux d'échantillons cliniques, ce procédé consistant à utiliser une paire d'amorces d'amplification PCR dégénérées. Cet ensemble d'amorces, qui utilise des restes de désoxyinosine pour équilibrer des erreurs d'appariement de troisième position au niveau de positions spécifiques, reconnaît les séquences nucléotidiques proches du site de liaison de récepteur des virus poliomyélitiques. Il s'agit ici de séquences particulières des virus poliomyélitiques, lesquelles sont entièrement préservées au niveau des acides aminés. En conséquence, ces amorces de PCR ne reconnaissent pas des entérovirus n'appartenant pas à la catégorie des virus poliomyélitiques. Tous les sérotypes du virus poliomyélitique (40 génotypes apparentés au vaccin contre le polio et 120 génotypes du virus poliomyélitique de phénotype sauvage provenant de différentes parties du monde) ont donné des résultats positifs. Toutes les 14 souches prototypiques des entérovirus n'appartenant pas aux virus poliomyélitiques, ont donné des résultats négatifs. L'invention se rapporte également à une série d'amorces d'amplification PCR dégénérées qui différencie entre les trois sérotypes du virus poliomyélitique de phénotype sauvage, ainsi qu'à un procédé de détection de la présence des trois sérotypes au moyen d'une technique d'amplification d'acide nucléique.

Abstract: A fluid-powered, laterally tiltable tool actuator (40). A tool has a pair of clevises (36,38), and an actuator (40) has a generally cylindrical body (42) with an output shaft (50) rotatably disposed therein with an axis in general parallel alignment with a forward rotation plane through which the tool (34) is rotatable on a backhoe arm (20) by the operation of a rotation link (24). A bracket is attached to the body and has a pair of clevises (36,38) for pivotal attachment to the vehicle arm (20) and rotation link (24). The output shaft (50) has a pair of shaft attachment members (70) at each end for attaching the shaft to the corresponding tool clevises (36,38). The first pair of shaft attachment members  (70) is rigidly fixed to the shaft and attached to a first tool clevis (36,38). The second pair of shaft attachment members is pivotally attached to the shaft (50) and pivots in a plane generally parallel to the longitudinal axis of the shaft. The pivoting attachment members can be adjustably positioned to accommodate various distances which separate the first and second tool clevises (36,38) of different tools to allow the pivoting attachment members to be readily attached to a second tool clevis. A linear-to-rotary transmission device disposed within the body produces rotational movement of the shaft (50) relative to the body (42) to produce lateral tilting of the tool (34) in a lateral plane generally transverse to the forward rotational plane.

Abstract: There is disclosed a process for the preparation of viscosity-stable polyurethanic elastomer. 
     The present invention pertains to an improvement in stability of viscosity of polyurethanic elastomer through the actions of a suitable catalyst for polymerization and a chain-growing agent. For the polyurethanic elastomer, a prepolymer which is obtained by reacting a diol component consisting of a low molecular weight diol compound having an average number of molecular weight of 50 to 500 and a high molecular weight diol compound having an average number of molecular weight of 1000 to 3000 with an excess of diisocyanate compound in the presence of suitable catalyst cf metallic compound is elongated by the action of chain-growing agent. This elongation of the prepolymer is stopped by adding a monoamine compound, a chain-growth stopper, followed by addition of light stabilizer. 
     Without degradation of intrinsic physical properties including elongation, tensile strength and elastic recovery, it is capable of remarkably improving thermal resistance and viscosity stability.

Abstract: The method provides a holographic simulation of objects or surfaces. A reduced size model of the object to be simulated is made. This is holographically recorded with at least one wavelength different from ultraviolet light. The image is reconstructed by divergent projection with the same number of laser wavelengths in the visible range, as real size images at required positions. Preferably in the hologram recording, the coherent light beam is split up by a beam splitter into a partial light beam to illuminate the object and the remaining part of the beam is a reference beam. The hologram of the object is preferably irradiated with a coherent laser beam. Weak incoherent light may be used for reconstruction of the hologram. The beam strengths may be adapted to the surrounding brightness in the hologram reconstruction.

Abstract: A belt-type continuously variable transmission (1) has a pulley side pressure control valve (40) for controlling side pressures of driving and driven pulleys (5, 8) and a controller (60) for controlling the pulley side pressure control valve (40). This controller (60) has a correcting device (63) for correcting a belt transmission torque calculated by a belt transmission torque calculator (62) when the polarity of the belt transmission torque changes. This correcting device (63) adds to the belt transmission torque for a predetermined time a correction value (T DG ) corresponding to a peak torque (T P ) of the belt transmission torque (T BLT ) arising at times of throttle opening and closing. That is, because the nelt transmission torque is corrected in correspondence with the peak torque arising at times of throttle opening and closing, the side pressures of the pulleys (5, 8) are kept at suitable values at all times and slippage of the metal V-belt (7) is prevented.
