Abstract: A fan includes a sealed electronics housing, in which a printed circuit board having electronic components is arranged. The electronics housing is divided into an upper region and a lower region. A cooling wheel which is arranged in the lower region is axially adjacent to the printed circuit board. The printed circuit board has at least one central opening and a plurality of peripheral-edge openings or gaps in order to bring the upper region into fluid communication with the lower region. Air is drawn out of the upper region into the lower region by the cooling wheel via the at least one central opening and, via the plurality of peripheral-edge openings or gaps. The air is fed back into the upper region. An air circuit having at least one air flow develops along a surface of the printed circuit board on which the electronic components are arranged.

Abstract: The invention relates to a radial fan with an impeller (100) and a cylindrical drive unit (200) that can be rotated around the longitudinal axis, whereby the impeller (100) consists of a baseplate and of blades (101) arranged on the baseplate, and whereby the blades are located on the side facing the main air flow, and it is characterized in that the impeller (100) can be operatively connected to the drive unit (200) in two fastening planes.

Abstract: For exhaust gas recirculation in internal combustion engines operating, for example, with low sulphur marine diesel oil, an exhaust gas cooler with a cooling unit may be applied that uses a liquid injection system to maintain clean and/or clean a cooling surface of the cooling unit. The liquid injection system may provide liquid into an exhaust gas passage upstream of and or along a condensation starting region the cooling surface, thereby reducing the formation of films and deposits from particulate matter and condensing liquid of an evaporated liquid within the exhaust gas such as sulphuric acid and/or water, as those deposits could otherwise at least partially block the exhaust gas cooler.

Abstract: The invention provides improved backpack and waist bag carrying systems in which a waist bag rotates through a lower compartment of a backpack to allow the bearer of the backpack to access the contents of the receiver of the waist bag by rotating the waist bag to the front of the bearer's torso. One or more doors are provided in one aspect to secure the receiver of the waist bag in the lower compartment of the backpack but permit the egress of the receiver through the opening covered by the door, which may be tensioned away from the opening by a tensioning element when the free end of the door is released.

Abstract: A motor, comprising an electronics housing having integrated motor electronics, a stator, and a rotor. The stator comprises a stator bushing and a laminated stator core having motor windings. The stator bushing is arranged axially between the electronics housing and the rotor. The motor according to the invention has an air-conveying element connected to the rotor in a rotationally fixed manner and at least one axially extending passage opening arranged in the stator bushing. The air-conveying element is arranged axially between the stator bushing and the rotor and has a circumferential axial intake opening on the side of the stator bushing. During motor operation, the air-conveying element sucks in an axial volumetric air flow at an external wall of the electronics housing through the intake opening and the passage opening.

Abstract: The present invention concerns an electronic housing for an electric motor, consisting of a housing holder part with a housing floor and a housing wall comprising the housing floor. A housing opening lies opposite the housing floor. Arranged in the housing holder part is a motor electronic component with an electronic printed circuit board, which is arranged parallel to the opening plane of the housing opening. Detachably arranged on the electronic printed circuit board or on the motor electronic component, on a side of the electronic printed circuit board facing away from the housing floor is a contact protecting component, which covers this surface, from an electrically insulating material, which has at least partially a grid structure as an air outlet.

Abstract: The invention provides a carry-on wheeled luggage (1) for photographic equipment that has an interior compartment (80) deep enough to accommodate a large article of photographic equipment such as at least a 400 mm 2.8 f-stop aperture telephoto lens.

Abstract: The invention provides improved backpack and waist bag carrying systems in which a waist bag rotates through a lower compartment of a backpack to allow the bearer of the backpack to access the contents of the receiver of the waist bag by rotating the waist bag to the front of the bearer's torso. One or more doors are provided in one aspect to secure the receiver of the waist bag in the lower compartment of the backpack but permit the egress of the receiver through the opening covered by the door, which may be tensioned away from the opening by a tensioning system when the free end of the door is released. The receiver is tapered to easily fit into the lower compartment and remain in that compartment due to friction with the walls defining the compartment.

Abstract: A water-resistant connector for use with fabric and sheet-like material comprises two plates stitched to each other on either side of and through the fabric or sheet-like material with at least one gasket made of an elastomeric material such as neoprene being placed between one of the plates and the fabric or sheet-like material. The gasket is stitched through and compressed between the plates so as to press against the stitching for water resistance. A suitable elastomeric material is a sheet of elastomeric compound adhered to either side of a reinforcing scrim.

Abstract: The invention provides a backpack (10) and cooperating waist bag (100) carrying system. In one embodiment the backpack has a lower or lumbar region below the bag portion of the backpack that releasably contains the receiver of the waist bag when the belt of the waist bag is secured around the bearer's waist and the backpack is worn on the bearer's back. The receiver of the waist bag can be moved without having to take off the backpack so that the receiver of the waist bag is disposed to the bearer's front and the bearer can gain access to the contents of the receiver. The bearer can then move the receiver back to the lower region of the backpack and the combination of the backpack and the waist bag then will appear to be a normal backpack with a waist belt. While moving the receiver, the waist bag remains operatively connected to the backpack.

Abstract: A system for carrying articles from a belt worn on the body of a person or other animate bearer comprises a belt or elongated member (20) with a substantially planar rail (30) borne on the outside surface of the belt and a carrier (50) for articles attached to the rail by a sleeve sewn to the body of the carrier. The carrier (50) may be free to slide along the rail (30) or may be secured at least temporarily to the rail. The carrier (50) thereby can be moved along the rail when worn on the belt so that the bearer can place the carrier (50) in a more comfortable or useful position with respect to the body of the bearer and secure it in that position at least temporarily.
