Abstract: A dispenser for stored product such as food products includes a generally hollow housing having a cavity configured to retain product; an outlet provided at a lower portion of the housing with a proximal portion adjacent the cavity and a distal portion spaced from the proximal portion; a gate disposed between the cavity and the distal portion or disposed at the distal portion; an actuator coupled to the gate to selectively position the gate between a closed position and an open position, wherein in the closed position product disposed within the cavity cannot move to the outlet and in the open position product falls by gravity from the cavity to the outlet; and optionally an environmental control unit to control an environmental control apparatus to modulate at least one of temperature, moisture content, or oxygen content within the dispenser or an agitator assisting movement of the product to the outlet.

Abstract: A container for stacked food products, such as potato chips, is provided. The container includes composite laminate that includes one or more layers of cardboard. The container has a non-circular shape. The container has a horizontal cross-section with end portions that have a constant radius along their length and side portions that have a changing radius along their length wherein the end portions and the side portions transition between each other continuously.

Abstract: A device (1) for generating encrypted images which are only visible through a polarizing filter (5) oriented in a predetermined direction, comprises: a source (3) of digital information; an LCD screen (2) connected to said source (3) to form on its front face a matrix of chromatic filters which represents images; a polarizing layer (4) oriented in a predetermined direction and located behind a rear face of the LCD screen (2) to intercept a beam of light passing through the LCD screen (2) and oriented towards an observer of the front face.

Abstract: A multi-layer film (1), depicting a colour two-dimensional image which is only visible through a polarizing filter comprises an optically active layer (2) placed over a polarizing layer (3) and configured to form the image on its face opposite the polarizing layer (3) when said face is seen through the polarizing filter, the optically active layer (2) comprising a plurality of sheets (4) of optically active material placed over each other, at least one of which is shaped to form at least one portion of the outline of the image.

Abstract: A film (1) depicting a colour two-dimensional image which is only visible through a polarizing filter comprises an optically active layer (2) placed over a polarizing layer (3) and configured to form said image on its face opposite the polarizing layer (3) when said face is seen through the polarizing filter; the optically active layer comprises a plurality of areas (4) arranged side by side in said face to form corresponding portions of the image, each area (4) being mechanically stressed to a predetermined intensity so that the corresponding portion of the image has a predetermined colour when seen through the polarizing filter. Also described is an apparatus (6) for making the film (1).
