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: 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 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 wheeled carrier equipped with a handle assembly and wheels has both top and side doors covering openings for accessing the same compartment in the body of the carrier. A strap having an opening defined in the strap for receiving a handle assembly is provided to attach a carrier to a wheeled carrier in order for the carrier to be supported by the wheeled carrier.

Abstract: A carrier has a variable-length compartment for receiving a device of variable length, such as a lens with a hood that may be alternated between a reversed and an extended or operative position. The carrier has an expansion gusset region that allows expansion of the carrier along one dimension when the device is elongated, whereby the carrier is able to securely accommodate the elongated device within the compartment, and contraction of the carrier when the device is less elongated.

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.

A gasket may be provided encircling an eyepiece of the camera.

Abstract: A system for carrying articles on a user's belt, comprising a belt (10) having multiple loops (22) on its outside surface and an article carrier (1) having a sleeve (40) sewn to the body of the carrier at a first end (42) and detachably connected to the body of the carrier at a second end (44). A stiff tab (60) is sewn at one end thereof into the sewn connection of the body of the carrier to the sleeve. The other end of the tab (64) is unattached and overlapped by the sleeve when the sleeve is wrapped around the belt for supporting the carrier from the belt. The carrier can be moved along the belt and placed in different positions unless the free end of the tab is inserted through a loop on the belt in which case the carrier will be fixed in position with respect to the belt.
