The invention relates to a protective device for the sealing of a stern tube (1) of propeller-driven ships, in which an intermediate space is provided between the stern tube (2) and the propeller hub (3), which is covered by a tubular protective jacket (4) arranged concentrically to the propeller hub. Said protective jacket is firmly anchored to the stern tube (2) and engages over the propeller hub (3) such that an annular gap (5) is left open, wherein a ring (6), which is concentric to the propeller hub (3) and has a U-shape in the radial section, is arranged in the intermediate space between stern tube (2) and propeller hub (3) inside the protective jacket (4), the U-shaped opening of the ring being directed radially outwards. The aim of the invention is to provide an easily manageable and cost-effective solution. In order to achieve said aim, the invention provides that the ring (6) consists at least partially of a material (B) which can have a pourable consistency at room temperature (T = 20 °C).
B63H 5/16 - Arrangements on vessels of propulsion elements directly acting on water of propellers characterised by being mounted in recessesArrangements on vessels of propulsion elements directly acting on water of propellers with stationary water-guiding elementsMeans to prevent fouling of the propeller, e.g. guards, cages or screens
The invention relates to a fin stabilizer (1) for stabilizing water vehicles, comprising a pivotable stabilizing fin (2), a fin box (6) for receiving the stabilizer fin in the pivoted state, and at least one covering element (8) for at least partially covering a fin box opening, through which the stabilizer fin exits and enters the fin box during swiveling in and out, wherein the at least one covering element (8) is resilient. The invention also relates to a covering element for a fin box opening and a water vehicle having at least one fin stabilizer.

EVAPORATION SYSTEM, EVAPORATION METHOD, AND SEALING SYSTEM
The invention relates to an evaporation system for separating at least two liquids mixed with each other, comprising a reaction vessel for holding the mixture, a blow-in device for blowing a gaseous aerating agent into the mixture, a heating device for heating the mixture, and an outlet for leading away the blown-in aerating agent and for leading away liquid vapor, wherein a feed for introducing a gaseous fluid is arranged above a mixture surface in order to produce a gaseous transport flow to the outlet. The invention further relates to a method and to a sealing system.
B01D 1/14 - Evaporating with heated gases or vapours in contact with the liquid
B01D 3/34 - Distillation or related exchange processes in which liquids are contacted with gaseous media, e.g. stripping with one or more auxiliary substances
The invention relates to an axial bearing (1) for receiving axial loads that act on a rotatary element, wherein the axial bearing has ring retainers (10) for accommodating pushing pieces (8), which ring retainers (10) each have a positioning segment (14) for stationary positioning and a spring ring segment (12) for axially elastic deformation when a load limit acting on at least some of the pushing pieces (8) is exceeded, wherein a spring gap is formed between the spring ring segments and in each case a back-side housing segment. The invention further relates to a retainer for such an axial bearing.
F16C 27/08 - Elastic or yielding bearings or bearing supports, for exclusively rotary movement primarily for axial load, e.g. for vertically-arranged shafts
The invention relates to a sealing system (1) for sealing a shaft (2) that is located under water, in particular a propeller shaft of a ship. Said system comprises two sealing systems, the sealing system that is farther away from the propeller preferably having at least one lip seal (36) for separating an air chamber (28) from a lubricant chamber (30) and the sealing system that is nearer to the propeller having a slide-ring seal (44). The air pressure in the air chamber is greater than the lubricating-oil pressure in the lubricant chamber. The invention also relates to a method for sealing a shaft, in particular a propeller shaft, and to a watercraft.
A method is disclosed for preparing a fluid loaded with ingredients. Said fluid is set into a circular motion in a reaction container and ultrasonic waves and/or ultraviolet radiation is applied. A local radiation intensity is adapted to a specific concentration of the ingredients in the fluid, wherein at a high specific concentration, the local radiation intensity is higher than at a low specific concentration. A device for carrying out the method is also disclosed.
The invention relates to a seal assembly (100) for a component supported rotatably in relation to a further component comprising a bellows (10), a stationary seal element (8), and a rotatably seal element (6) supported in sliding contact with respect to the stationary seal element (8). A compressive force, which causes a sealing effect between the stationary seal element (8) and the rotatable seal element (6), is produced by the bellows (10).
F16J 15/34 - Sealings between relatively-moving surfaces with slip-ring pressed against a more or less radial face on one member
F16J 15/36 - Sealings between relatively-moving surfaces with slip-ring pressed against a more or less radial face on one member connected by a diaphragm to the other member
Disclosed is a sealing system for sealing shafts against liquid media, for example propeller shafts, impeller shafts, rudder stocks of ships and the like, with the opposing corner regions of said sealing system that are located radially inside, of a clamping space for clamping at least one sealing ring, being formed by inclined run-on surfaces that diverge when viewed radially from the inside towards the outside, wherein for accommodation in the clamping space a clamping section of the sealing ring comprises two opposite edge regions that are formed by inclined surfaces that correspond to the run-on surfaces, and a sealing ring for such a sealing system.
