Abstract: A housing of a centrifugal blower for use in an air conditioner is provided that includes a rotatably supported fan wheel, an inlet opening disposed in the axial direction of the fan wheel and an outlet opening disposed in the radial direction of the fan wheel. A widening diffuser is disposed downstream from the outlet opening in the flow direction, and the fan wheel is disposed in an inner volume of the housing. A crossover area formed from multiple openings is provided on at least one housing wall which delimits the inner volume. At least one chamber is disposed on the outside of the housing, the chamber completely covering the crossover area and being fluidically connected to the inner volume of the housing via the crossover area.

Abstract: A user obtains, views and stores image data of a selected celestial object from a network of available telescopes using a computer-generated user interface. Based on the selected object, information is accessed regarding each telescope from data sources such as databases and/or live data feeds to automatically select telescopes that are suitable for imaging the object, e.g., according to factors such as telescope type, power and configuration, location, weather conditions, visibility, and altitude. The user may select a particular telescope and imaging time from a schedule of available telescopes and imaging times. At the scheduled time, an image is recorded of the celestial object and communicated to a central data store for access by the user, e.g., via a web site.

Abstract: A numbering box for a press for printing bank notes has a stack of sensor boards in one-to-one correspondence with a stack of numbering wheels and each of the boards has an edge area at the printing face of the numbering box which carries an LED indicator of a status of magnetic signalling means on the respective numbering wheel. The boards are each connected to a motherboard in the numbering box. Data processing means in the numbering box may be connected to a remote computer by an optical fibre link. The sensor boards are closely spaced and each has an aperture to accommodate a bulky component of the or an adjacent board.
