Abstract: Provided is a utensil for cooking food under pressure including: a vessel and a lid; at least one locking member mounted to move on the lid between a locking position and an unlocking position; a control device for controlling the movement of the locking member, including an operating member suitable for being actuated by a user in such a manner as to cause the locking member to move; wherein the locking member is mounted on the lid in such a manner as to be urged by positioning resilient return means towards its locking position; and the operating member is mounted to be drivingly linked to the locking member in a manner such that the action by the user on the operating member causes the locking member to move towards its unlocking position.

Abstract: The invention relates to system conceived and designed to identify pieces of fruit, especially citrus fruits, affected by any amount of rot and to determine the automatic expulsion of these pieces from the conveyor moving them through the installation. The system comprises illuminating the fruits with UV-A band light in a computer vision unit, and capturing images of the illuminated fruits by means of a camera to send them to a general control member in order to detect fluorescences associated to the rot effect. The identified fruit is automatically expelled from the conveyor in an expulsion unit, the position of the defective fruit being determined with the aid of an encoder associated to the conveyor. The general control member is a PC type computer, equipped with specific application software.

Abstract: Heat-stable composition, destined to emit insecticidal vapors by being heated, which contains at least one insecticidal substance of the family of pyrethrinoids, a stabilizer chosen from among the compounds defined by the chemical formula ##STR1## in which R represents one or two optional alkyl radicals containing one to twelve carbon atoms, R' and R", alike or different, represent each an alkyl radical containing one to eighteen carbon atoms, R' and R" together can represent a divalent saturated hydrocarbon group containing two to seven carbon atoms, and R'" represents a hydrogen atom or an alkyl radical containing one to seven carbon atoms; and, optionally, an adjuvant inert to the insecticide and chosen from among diluents, thickening agents, perfumes, synergists, colorants, repellants, solid supports and comburants.

Abstract: A device intended to emit vapors emitted by an active substance, in particular an insecticidal substance, which comprises, in a rigid assemblyA. a reservoir intended to contain the active substance and having an evaporation surface for the emission of the active vapors,B. an electrical resistance associated with the said reservoir in such a way as to heat at least the part of the said reservoir which comprises, or is close to, the said evaporation surface, andC. a system for connecting the resistance to a source of electric current: the said reservoir comprisesI. a system of two plates of a porous or fibrous material, one of the large faces of one of the plates facing one of the large faces of the other, and a frame for the plates, which separates the space between the two plates from the exterior while leaving entirely or partially free at least one of the two large external faces of the two plates, which can thus serve as an evaporation surface, andIi.
