Abstract: An elongate wine bottle with an internal space for holding wine therein includes a hollow and cylindrical body with a closed bottom and a cylindrical neck extending to an open outer end of the wine bottle remote from the bottom. A thickness of a material from which the wine bottle is manufactured is the same over at least substantially the whole length of the wine bottle. The neck is provided along its outer surface with an external screw thread and only a single annular edge situated below the screw thread relative to the open outer end. A diameter of the circular cross-section of the body is at least substantially equal to a diameter of the circular cross-section of the neck such that the wine bottle has at least substantially one and the same bottle diameter along its whole length.

Abstract: The invention relates to a system and method of utilising live wallpaper on a mobile device, particularly for advertisement purposes. The system and method are operable to provide dynamic, animated and interactive advertising to mobile computing devices. The advertising is specifically targeted at the user of the mobile device and is presented to the user as live wallpaper when the device is active or as a screensaver when the device is in charging state.

Abstract: A low-flow stator (4), used upstream of a rotor (27) of a tank cleaning machine, includes a body (6) having a plurality of generally helical passageways (38) extending from a front surface (10) of the body to a rear surface (12) of the body. Each passageway has an entrance (40) and an exit (42), the exit being completely circumferentially offset from its corresponding entrance.

Abstract: A rotary spray nozzle directional tank cleaning machine has a first, stationary housing, a second housing mounted to the first housing for rotation about a first, typically vertical axis, and a third housing mounted to the second housing for rotation about a second axis. The second axis is at a first, acute angle to the first axis. The second housing is driven about the first housing through an impeller driven gear train by the pressurized cleaning liquid passing therethrough. The third housing is driven by a pair of bevel gears mounted to the first and third housings. One or more nozzles, mounted to the third housing, direct cleaning liquid along a third axis oriented at a second, acute angle to the second axis. The first and second, acute angles are preferably 45.degree. to create a hemispherical spray pattern.
