Abstract: A method is provided for controlling a boat. The boat is adapted to float in a body of water. The boat includes a hull having a longitudinal extension along a hull longitudinal axis, a lateral extension along a hull lateral axis and a vertical extension along a hull vertical axis. The boat also includes a set of drive units, the set of drive units comprising at least one drive unit. Each drive unit in the set is arranged such that it, during driving of the boat, is adapted to be at least partially submerged into the body of water; adapted to be pivotable, relative to the hull, around a drive unit longitudinal axis that is substantially parallel to the hull longitudinal axis such that a drive unit roll angle can be varied, and adapted to be pivotable, relative to the hull, around a steering axis that forms an angle with the drive unit longitudinal, axis such that a drive unit steering angle can be varied.

Abstract: The invention discloses an electronics device for personal use, comprising at least a first main surface, and at least a first antenna for communication via electromagnetic waves between the device and a second party. The antenna is an array antenna comprising at least a first and a second antenna element, and is arranged on said first main surface. Suitably, the electronics device is a portable computer comprising a lid which may be opened or closed, said first main surface being the lid, so that the antenna is arranged in the lid of the portable computer.

Abstract: The invention discloses a repeater antenna for use in point-to-point applications in telecommunications systems in the microwave range, intended for connecting transmissions from a first radio unit at a first site to a second radio unit at a second site. The repeater antenna is essentially plane, and is designed as a traveling wave antenna with at least a first and a second antenna beam, so that the first beam can be used for transmissions to and from said first radio unit, and the second beam can be used for transmissions to and from said second radio unit.

Abstract: A transport package for a boat propeller drive (2) that has a suspension fork (6) for suspending the drive in a suspension plate mounted on the stern transom of a boat. The package includes a bottom plate (14) and a cover that can be removed from the bottom plate. The drive is held in a fixed position in the package by means of upper and lower spacing elements (21, 22). When the cover and the upper spacing elements are removed, the suspension fork is exposed and the drive is held stable in an upright position by the bottom plate together with the lower spacing elements to serve as a mounting fixture.

Abstract: Apparatus for adapting a propeller system including a propeller shaft (15, 16) and a propeller (7, 8) adapted to be mounted on the propeller shaft (15, 16). The propeller system includes a propeller (7, 8) connected in a rotationally fixed manner to a propeller shaft (15, 16), the propeller shaft (15, 16) having a portion provided with splines (19, 20) which cooperate with corresponding splines (25, 28) inside the hub (23, 26) of the propeller (7, 8) in order to obtain the rotationally fixed connection, where the splines (19, 20) on the propeller shaft (15, 16) and in the hub (23, 26) of the propeller (7, 8) are helical, with a predetermined oblique angle (?, ?). The invention also relates to a propeller shaft (15, 16) and a propeller (7, 8) which are intended to be used in the propeller system.

Abstract: Method and device for regulating the phase angle between a first and a second crankshaft of an internal combustion engine. The engine includes primary cylinders that communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston that is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston that is connected to the second crankshaft. The first and second crankshafts are connected to each other by means of a transmission adapted with the device that includes a crankshaft extension for obtaining the control of the phase angle, the extension being fixed against rotation and displaceably connected to one of the crankshafts and via a grooved portion rotationally connected to the second of the crankshafts. When the crankshaft extension in displaced, rotation is obtained in the grooved portion that results in a corresponding phase angle shift.

Abstract: Propulsion unit for marine vessels with a gear or bearing housing (6) in which a propeller shaft (7) with a surface-breaking propeller (8) is carried. In a horizontal plane the propeller shaft forms an angle (.alpha.) to a guide fin (9) so as to create a resultant force (R) of the pressure force (P) of the propeller and the side force (S), with the resultant force being aligned with the longitudinal direction (C.sub.L) when the vessel is travelling straight ahead.
