Abstract: The present invention relates to a mannequin (1) provided with a video camera (10) that is hidden and connected to a processing system (14) capable of determining, for statistical purposes, age, gender and ethnic group of those people who enter the field of action of the video camera (10).

Abstract: A method for recognition between a first and second object represented by at least one first image and at least one second image, includes defining rectangular assemblies of random pixels; filtering the first image with first n filters obtained from the assemblies of pixels to obtain n first filtered matrices; classifying the n first filtered matrices by providing a first center and a first radius within a space of N dimensions; filtering the second image with the first n filters to obtain n second filtered matrices; classifying the n second filtered matrices by providing a second center within the space of N dimensions; and comparing the first center and first radius with the second center.

Abstract: A plant for continuously retorting oil products contained in shales and sands comprising a substantially horizontal retort furnace into which said shales and sands are introduced by means of hoppers and metering devices and placed on metal conveyors moving in counter-current to gases, means being provided for placing said shales and sands onto said conveyors with a suitable thickness and for stirring the shales and sands. One or more combustion chambers are arranged outside said retort furnace for producing hot gases, and one or more input zones are located along the retort furnace for admitting hot gases into the retort furnace, causing the hot gases to mix with circulating gases which have been preheated by removing sensible heat from the exhausted shale and sand material. A direct contact condenser at the furnace head utilizes cold fluid to condense distilled oil products, and a decantation tank is arranged beneath said condenser for freeing the process gases from the dust.

Abstract: A plant for retorting oil products contained in shales and sands comprising a continuous retorting in a substantially horizontal retort furnace having any cross-section, into which said shales and sands are introduced by means of hoppers and metering devices and placed on metal conveyors moving in counter-current to gases, means being provided for placing said shales and sands onto said conveyors with a suitable thickness and for stirring the shales and sands, one or more combustion chambers arranged outside said retort furnace, in which hot gases are produced, and one or more input zones along the retort furnace for the admission of hot gases into the retort furnace which hot gases mix with pre-heated circulating gases at the expenses of the sensitive heat of the exhausted shale and sand material, a direct contact condenser at the furnace head, provided for condensing distilled oil products by a cold fluid and a decantation tank arranged beneath said condenser for depurating the process gases from the dust.

Abstract: A process for making modular element for heat exchangers with thermoplastic tubes consisting of a plurality of tubes connected to one another by spacers located at intervals allowing the mutual tape-like positioning of the tubes. Also a process for making a tube nest consisting of a plurality of such modular elements.
