20130313786 | Sealing Ring - In seal rings for the sealing of shafts for propeller shafts, impeller shafts, rudder shafts of ships, an arrangement is provided, wherein a clamp-in element in allocated housing-fixed support rings as an installation space is provided with an adjoining intermediate part as a membrane and an angled element facing toward the shaft with formation of a seal lip for contact on the shaft. Thereby the contact region of the seal lip on the shaft is formed by a circle-shaped seal region with a constant radius over the entire adjustment range. Alternatively, the contact region of the seal lip on the shaft is formed by a circle-shaped seal region, whereby in the unloaded condition the seal region in the region facing toward the medium to be sealed comprises a smaller radius relative to a radius in the rearward region of the seal lip. | 11-28-2013 |
20140048461 | Seal Arrangement for a Rotating Ship Propeller Shaft - A seal arrangement for a ship's propeller shaft includes at least one oil-filled seal chamber bounded by seal rings around the shaft, as well as an oil reservoir tank, an oil supply line connecting the tank to the bottom portion of the seal chamber, an oil circulation pump interposed in the supply line between the tank and the seal chamber, and an oil return line communicating from the upper portion of the seal chamber back to the tank. Thereby, oil is continuously circulated through the seal chamber, and thereby flushes out any contaminant particles, air or water that might enter the seal chamber. | 02-20-2014 |
20140346738 | Seal Apparatus for a Ship Propeller Shaft and Method of Making the Apparatus - A seal apparatus, for sealing around a rotating shaft such as a propeller shaft of a watercraft between the exterior water and an interior lubricant space, includes a multiple seal arrangement with plural seal rings forming seal chambers therebetween, and plural fluid medium lines supplying and/or returning a respective fluid medium to a respective seal chamber. A section of a first medium line is formed as an axial passage through a housing of the apparatus, and a section of a second medium line is formed by a pipe arranged within the axial passage in the housing. A method of making such an apparatus especially by retrofitting an existing seal arrangement involves inserting a pipe into an axial passage in the housing in order to establish two medium lines through the housing where there was previously only one medium line. | 11-27-2014 |

20090071388 | Watercraft having a kite-like element - The invention relates to a water craft comprising a kite element, which is connected to the water craft by a traction cable. The water craft is characterized in that the kite element is equipped with adjusting devices and an energy generation unit, which delivers energy when the tractive force that is exerted on the traction cable is modified. | 03-19-2009 |
20090212574 | Positioning device for a free-flying kite-type wind-attacked element in a wind-powered watercraft - Disclosed is a positioning device for a free-flying kite-type wind-attacked element that comprises a profiled wing, is used as the exclusive, an auxiliary, or an emergency drive unit, and is connected to a watercraft via a traction rope. The positioning device is provided with a winch that encompasses means which cause the traction rope to be taken in when a given first tractive force is not attained and/or when the flow is about to stop or has stopped abruptly and/or cause the traction rope to be veered when given a second tractive force and/or a given inflow velocity are/is exceeded. | 08-27-2009 |
20090266283 | Placement system for a flying kite-type wind-attacked element in a wind-powered watercraft - Disclosed is a placement system for a free-flying kite-type wind-attacked element in a watercraft in which the kite-type wind-attacked element comprising a profiled wing is connected to the vessel body via a traction rope. Said wind-attacked element can be guided from a neutral position on board the watercraft into a raised position that is free from obstacles located at the same or a higher level. An azimuthally pivotable fixture is provided by means of which the wind-attacked element can be brought into a position in which the same is exposed to a sufficient wind effect. Furthermore, a docking receiving device is provided which is to be removably connected to the docking adapter of the wind-attacked element on the side facing away from the wind while also allowing the wind-attacked element to be furled with the aid of automatically engaging holding means. | 10-29-2009 |
20100192825 | Watercraft having a kite-like element - The invention relates to a water craft comprising a kite-type element, which is connected to said water craft by means of a traction cable. Said water craft is characterized in that the kite-type element is equipped with adjusting devices, which are supplied with energy from the water craft, said energy being transmitted in the traction cable or by an element on the latter. | 08-05-2010 |
20100282153 | Steering Unit for Free Flying, Confined Wing Element - The invention relates to a steering unit for a wind propulsion system, the steering unit comprising a first fixed attachment means for securing a first end of a tractive cable the second end of which is secured to a device or a vehicle to which a tractive force shall be transferred, a second attachment means for attaching a number of tractive lines, the second end of which being secured to an aerodynamic wing element, a mechanical support frame connecting the first attachment means to the second attachment means for transferring a tractive force. The invention aims at providing such a steering unit with improved design for better maneuverability and stability. According to the invention the second attachment means of the improved steering unit comprise at least one upper fixed attachment point, a left moveable attachment point, a right moveable attachment point, and steering actuator means for varying the distance between the upper fixed attachment point and the left moveable attachment point and for varying the distance between the upper fixed attachment point and the right moveable attachment point. | 11-11-2010 |
20120111251 | Aerodynamic Wind Propulsion Device Having Active And Passive Steering Lines And Method For Controlling Of Such A Device - The invention relates to an aerodynamic wind propulsion device, particularly for watercrafts, comprising an aerodynamic wing being connected to a steering unit located below the aerodynamic wing via a plurality of tractive lines, at least one pair of two active steering lines being connected to the aerodynamic wing at two points in distance and being coupled to a drive unit at the steering unit, a tractive cable, a first end of the tractive cable being connected at the steering unit to at least two of the tractive lines and a second end of the tractive cable being connected to a base platform, the aerodynamic wing having an aerodynamic profile which generates an uplift force, and, according to a first aspect of the invention, is characterized by a pair of two passive steering lines, wherein each of the two passive steering lines comprises a lower section and an upper section, wherein a second end of the lower section of each passive steering line is connected to a first end of the upper section of the respective passive steering line via a connecting member, second ends of the upper sections of the two passive steering lines are connected to the aerodynamic wing at two points in distance, and first ends of the lower sections of the two passive steering lines are connected to each other to form a continuous passive steering line section passing through the steering unit in order to passively follow a deformation of the aerodynamic wing.
