  • Patent number: 7109291
    Abstract: The invention concerns novel compounds capable of modulating the activity and stimulating the production of catalytic antibodies. More particularly, the invention concerns a compound capable of increasing the activity of an antibody having specific affinity for the catalytic site of the antibody, and it is not immunogenic. Such compounds are useful in particular for therapeutic treatment or prevention of a pathology related to an enzymatic deficiency, to stimulate in vivo hydrolysis of xenobiotics, drugs, medicines or any other molecule potentially toxic for the organism or for preventing or inhibiting allergic reactions.

  • Patent number: 5855941
    Abstract: Materials, for example, plant-based food products, are subjected to heat and pressure in a processing enclosure, wherein the pressure is greater than the pressure of the atmosphere. The heated, pressurized materials are then subjected to a pressure-reduction phase during which the pressure in the processing enclosure is reduced at a rate greater than 500 millibars per second and by an amplitude greater than 1 bar. The rapid pressure-reduction phase of the invention contributes to the production of processed materials having a slightly spongy structure that is due to the presence of micro-cavities that promote the recapture of subsequent moisture.

  • Patent number: 5301632
    Abstract: A check sample of a deep-frozen product or a product is provided, whose keeping, conserving or preserving temperature, which is below ambient temperature, must be controlled or checked. The sample includes a case or envelope, which is sealed in an inviolable manner and, in the case or envelope, a meltable object having a predetermined shape different from the internal shape of the case. This object has a melting point below or equal to the thawing or keeping temperature of the product and the initial shape of the object is impossible to reconstitute following thawing or reheating, even of a partial nature, of the product. According to the invention, the case comprises a first part made invisible and integral with the product or a pack containing the latter by insertion into the pack or the case a second part, which is visible and integral with the first part.

  • Patent number: 4940912
    Abstract: The motor includes a rotor (2) with permanent magnets and a stator (3) that surrounds the rotor and includes reluctance pads (9, 10) provided to place the rotor (2), upon stopping, in a position where the startup of the motor will be assured. The reluctance pads (9, 10) are asymmetrical with respect to the magnetic axis (A) of the coils of the stator (3) and include notches (4), at least some of which serve to accommodate at least one coil of the stator (3), in order to assure obtaining a maximum winding coefficient.

  • Patent number: 4281263
    Abstract: A tubular stator capable of creating a magnetic field having both linear and rotary components comprises a tubular magnetic frame formed from longitudinal magnetic elements which are angularly spaced. The magnetic elements have teeth which extend radially inwardly. Circular induction coils are disposed between the teeth and undulating coils are disposed longitudinally between the magnetic elements. A magnetic sleeve surrounds the magnetic frame.An electric motor comprises a cylindrical rotor mounted within the tubular stator so as to be rotatable and translatable.
