Abstract: A device for reducing the size of dry ice granules for dry ice cleaning devices including a supply of dry ice to a device for mixing of dry ice particles with the flow of gaseous medium. The device includes a die with a set of orifices for granulate passing and a granulate pushing-through member for pushing the granulate into the die. The die is placed in a body with at least one sloped surface inclining to the inside of the body towards the die, which, the body, is connectable to a supply of dry ice granulate to a device for mixing of dry ice particles with the flow of gaseous medium in a dry ice cleaning device, where above the die a granulate pushing-through member is movably mounted.

Abstract: Dry ice container for dry ice cleaning devices comprises the container for dry ice closed by the lid (2) on the upper side, and provided by the opening (3) for drawing out dry ice pellets on the lower side. The container (1) has the bottom (4) sloped towards the opening (3) for drawing out the pellets. The linear-movable member (5) is arranged in the chamber (6) at the bottom (4) of the container (1) transversely to the axis of the container (1). The member (5) has the shape of a gutter in which groups of separated openings (5a, 5b, 5c) are provided, to which at least one pellets plowing element (5d) is placed in the member (5). Each group of openings (5a, 5b, 5c) pertains to one opening (3) for drawing out the pellets.

Abstract: Device for mixing solid particles of dry ice and the flow of gaseous medium including a feeding element (2) rotatively placed within the fixed housing (1) having openings (12, 13) for the flow of gaseous medium and/or the flow of gaseous medium with solid particles. Between the fixed housing (1) and rotatively placed feeding element (2) the immovable elastic membrane (3) is placed. The fixed housing (1) is at the side of the elastic membrane (3) provided by at least one sealed pressure chamber (14) connected with the opening (13) for the flow of gaseous medium and/or the opening (12) for the flow of gaseous medium with solid particles.

Abstract: Disclosed is a projector image correction method and system that actively modifies a projected image based on observed distortions in the reflected image from the projection surface. The method and system utilize a projector for displaying an image or motion picture on a screen, a camera for capturing the projection surface and projected image, an image correction unit for processing the differences between the captured image and the projected image, and an algorithm for interpreting the camera and projector image differences and effectuating the active correction of the projector image. Correction data from the camera image is utilized to correct the projected image by superimposing the data over the image for each frame, accounting for image distortion due to rough or multi-colored surfaces that otherwise change the projected image quality on the projection surface.
