Abstract: The surgical kit comprises at least one elongate strip for supporting the urethra of a patient, the strip comprising a knit of yarns forming empty spaces between one another, at least in the longitudinal middle portion of the strip that is to extend transversely under the urethra when the strip is implanted, said knit comprising both reinforcement constituted by longitudinal chains and an intermediate trellis transversely interconnecting the chains. In order to guarantee light obstructive support of the urethra, the treatment kit further comprises suture means adapted to be connected to the chains of the knit by being passed through the empty spaces so as to join the middle portion of the strip with the anatomical tissue under the urethra at least two connection spots in alignment in a direction that is substantially perpendicular to the longitudinal direction of the strip.

Abstract: Method and device for the selective extraction of compounds, particularly biochemical compounds having a high added value, from a complex solution. The method makes use of a monoenzyme reactive membrane system (3, 4, 5, 6) in a liquid medium, at the interfaces of which an electrochemical potential gradient of one of the reagents creates asymmetrical conditions which force the reversible reaction catalyzed by the reactive membrane system to operate in opposite directions on either side of said system, the passage of the compound to be extracted from one side to the other being favored by the presence on both faces of said system of barriers (5) which confine a compound other than the compound to be extracted. Device for implementing such method. Application to the extraction of compounds which are interesting from a biochemical point of view by concentration and accumulation on one side of the membrane system.

Abstract: The invention concerns a process and a device for roasting an agro-food product in the form of grains.The process consists of fluidizing an auxiliary body in the form of fine solid particles in an enclosure 1, and putting the grains of the product to be roasted in flotation in the fluidized bed of particles of which the temperature is adapted to roasting, to generate the roasting by the effect of the shocks of the fine particles of the auxiliary body with the grains of the product.The invention can be applied particularly for the roasting of grains of a product such as coffee, cocoa, etc.
