Abstract: An aerial digital camera comprises a housing 15, a lens, a frame 45, an image sensor 35 mounted on the frame, at least three flexure bearings 51 connecting the frame and the housing, the flexure bearings allowing a displacement of the frame relative to the housing in a displacement direction 67 parallel to a light receiving surface of the image sensor, a spring 69 providing a biasing force between the housing and the frame oriented in the displacement direction; and an actuator 71 for displacing the frame relative to the housing against the biasing force of the spring.

Abstract: A method and apparatus for cleaning candles in a candle filter using a cleaning fluid that flows inside the candle from the side of the filtrate, whereby said fluid is pressed in an opposite direction to the direction of the filtrate from the inside to the outside, through said candles, by a gaseous medium subjected to an overpressure. Water is or can be used as an appropriate cleaning fluid and air is used as a gaseous medium. The prior art teaches nozzle-shaped contractions that are respectively disposed on the outlet end of the candles or deflectors arranged inside the candle at a distance from said contractions, whereby the in-flowing cleaning fluid is deflected towards all sides in the direction of the inner walls of the candles, are provided for distribution of said cleaning fluid.

Abstract: A method of operating a plant for filling containers by moving a liquid such as water through an apparatus with at least one portion for receiving the liquid before it is filtered and at least one portion for receiving the liquid after it is filtered, so that the liquid moves from at least an upper area of apparatus to lower area of the apparatus to be transferred to bottles or other containers.

Abstract: The invention relates to a method for controlling an electronically directly driven focal-plane shutter which has two lightproof curtains, each of which is associated with, and controlled by, an electric drive motor. The drive motors move the curtains across an image field. One curtain starts in a closed position, and the other curtain starts in an open position prior to taking the exposure. So as to achieve operating sequences of the two curtains which are as identical as possible, both drive motors initially are driven simultaneously in an "open" direction. The curtain which starts in the open position first is pressed against a defined open-position stop. Then, by reversing the associated drive motor, that curtain is moved in the "close" direction to complete the exposure.

Abstract: A device for indicating the depth of field of a camera having aperture setting means and range setting means. The device comprises a plurality of optically active elements positioned for view in the camera viewfinder and scale means associated with the optically active elements. Means are also provided which are responsive to the camera aperture setting and the range setting to select adjacent ones of the optically active elements to indicate the depth of field.
