Abstract: Marine propulsion unit, where said unit comprises a streamlined body, where said body has a front end and a rear end, where in use the front end will be facing upstream and the rear end downstream, where the front end has a larger cross section perpendicular to the intended travelling direction than the rear end, and where the front end is provided with a water inlet opening, where said opening is in communication with an impeller, which impeller rotates around an axis parallel to the intended travelling direction, where said impeller has one or more vanes whereby the water entering the front end is expelled radially away from the impeller's rotating axis, where said expelled water is forced through one or more rectifier nozzles directing said expelled water along the outer surface towards the rear end of the streamlined body.

Abstract: Support structure for light-weight construction elements which is consisting of elongate strips (10; 110; 210) of a strong material, wherein each strip (10; 110) is provided with slits (14) starting out from one of its longitudinal edges (12), the width of which is slightly larger than the thickness of the material and, wherein alternatingly in the longitudinal direction of the strip (10; 110; 210) the slits (14) are diagonally extending forwardly and diagonally backwardly and, wherein the individual strips (10; 110; 210) by means of the slits (14) are inserted into each other in such a way that the longitudinal directions of the strips (10; 110; 210) inserted into each other each are perpendicularly positioned with respect to each other, as well as a method for producing such a support structure.

Abstract: A control system including a personal computer (1) for controlling a process. The personal computer (1) includes a communications processor (14), which is connected to a field bus (2). Sensors (3, 4) and/or actuators (5, 6) are connected to the field bus (2). A monitoring unit (16) monitors a cyclic data transmission on the field bus (2). The monitoring unit (16) also causes a PC processor (7) to process data received at the field bus (2) by means of a control program, if at least one predetermined condition is met, e.g., a change in the process data. Thereby, the PC processor (7) is relieved of the burden of continuously polling the process data. The process data are stored in a memory (15). The control system is used, in particular, in communications processors for personal computers.

Abstract: This invention is directed to a process for preparing aldehydes by hydroformylation of monoterpene compounds, which comprises reacting a monocyclic or bicyclic monoterpene compound with at least one double bond at from about 70.degree. to 160.degree. C. under a pressure of from about 100 to 400 bar and in the presence of a catalyst mixture of tertiary phosphines and rhodium carbonyl complexes containing tertiary phosphines. The aldehydes prepared are useful as perfuming agents.
