Abstract: An electrophotographic imaging device employs a continuous form sheet having a plurality of segments divided by perforations. An image is formed on a predetermined area of each of the segments in accordance with image data. It is discriminated whether an image is printed, in accordance with the image data, on a segment of the continuous form sheet which is to be discharged out of the imaging device. If it is discriminated that the segment is discharged without an image being printed in accordance with image data, a pair of marks are printed on the segment. The discriminating mechanism and the mark printing mechanism can be disabled when a page length of a sheet of the continuous form sheet has a predetermined value.

Abstract: A method for producing power comprises compressing gas from an ambient source during a first period of time; storing the compressed gas in a storage reservoir; and supplying said compressed gas from the storage reservoir to a gas turbine during a second period of time to produce electric power.

Abstract: A vessel made of composite material wound on a metallic liner is tested via holographic interferometry, in which the interference of two holographic images of a tested zone are taken under two different states of thermal cycling. The thermal cycling is homogeneously applied to the entire liner, via a heated fluid placed inside the vessel. The interferogram is made outside the vessel, where a second image is made after having raised the liner to a temperature different from the one duly measured when the first image is made. The second image shot is controlled by the detection, outside and near the vessel, of a variation of the outer infrared radiation emitted by the vessel, resulting from the liner temperature variation being equal to a predetermined threshold value.
