20090010856 | Composition, Comprising Hydrofluoric Acid, for Inhibiting Dental Erosion - The present invention relates to a composition, for inhibiting dental erosion, and the use thereof. The composition comprises an aqueous solution of hydrofluoric acid, in which the concentration of hydrofluoric acid is 0.05%-2.00% and the pH is between 2.5 and 4.5. | 01-08-2009 |
20120213716 | METHOD FOR ALLEVIATING THE UNDESIRED SIDE EFFECTS OF DENTAL BLEACHING - The present invention relates to a method for reducing or eliminating loss of minerals from the enamel and dental hypersensitivity against temperature changes, in particular when caused by the bleaching of teeth with products containing hydrogen peroxide or other oxidizing agents. After the bleaching process the teeth are treated with a calcium hydroxide containing solution, and subsequently the teeth are treated with a fluoride solution. | 08-23-2012 |
20140242000 | COMPOSITION, COMPRISING HYDROFLUORIC ACID, FOR INHIBITING DENTAL EROSION - The present invention relates to a composition, for inhibiting dental erosion, and the use thereof. The composition comprises an aqueous solution of hydrofluoric acid, in which the concentration of hydrofluoric acid is 0.05%-2.00% and the pH is between 2.5 and 4.5. | 08-28-2014 |

20100311291 | MARINE POWER SPLITTING GEARBOX - A power splitting gearbox is provided that allows a single prime mover to distribute power, for example torque, to multiple final drive assemblies, such as surface drives or other final drives. The power splitting gearbox can be provided downstream from a marine transmission and can be mounted directly to a transom of a marine vessel. The gearbox can have a back wall that accepts and supports mounting surfaces of the multiple final drive assemblies such that the gearbox bears the weight of the multiple final drive assemblies. The gearbox has two outputs that rotate in opposing directions so that a pair of final drive assemblies mounted to the gearbox will counter-rotate a pair of propellers for providing a propulsive force that moves the marine vessel. | 12-09-2010 |
20110217177 | Stepped Surface Propeller - A marine surface propeller, and blade therefore, which is surface piercing and partially submerged, and includes a blade geometry that improves distribution of pressure and control to wetted and ventilated regions. Preferably, the feature has a positive step (ramp, cup, interceptor, indent or other geometric addition or intervention) between one fifth and four fifths chord length so as to create a high pressure peak or zone in what is now a low pressure zone on either the blade face or back or both and to create speed controllable wetted and ventilated regions. | 09-08-2011 |
20110263165 | Electric Marine Surface Drive - A marine articulated surface drive propulsion system is provided with a housing construction that allows the direct application of an electric motor for power onto the drive structure. Alternatively, it can include a power transmitting element for reducing the rate of rotation or the position of the motor shaft with respect to the propeller shaft. The drive can be retrofitted to existing boat hulls and does not require a dedicated hull. The electric motor can be fitted to the surface drive housing on the inside of the transom. It is contemplated that an electric motor with very small dimensions can be mounted in the drive thrust tube and ball socket, eliminating the need for U joints. Notably, if the propeller is left free wheeling it becomes the propulser for the electric motor to become a generator and recharge the batteries. | 10-27-2011 |
20110275254 | Waterjet Propulsion System and Method for a Marine Vehicle - A waterjet based propulsion system and method that utilizes more than one waterjet outlet port and controls the selective application of power to the waterjets with a splitter gearbox thereby improving the efficiency of the marine craft at low and high speeds. | 11-10-2011 |
20120258639 | Two-Into-Two or One Hybrid Power Device for a Marine Vehicle - A hybrid power device for a marine vehicle is provided that has two hybrid prime movers, an electric motor and a combustion engine, that distribute power, for example torque, to a single or dual propulsor, such as surface drives with propellers. The prime movers can apply power singly or in unison, but maintain substantially optimum propulsive efficiency in all cases. The power outputs of the prime movers are in communication with a power transmitting device such as a gear box that may combine the power outputs to drive a single propulsor, or may have a power-splitting embodiment driving dual propulsors. In addition, multiple hybrid power devices may be deployed in other embodiments. | 10-11-2012 |
20140060412 | Trimmable Rudder - A trimmable rudder system for a marine vessel such as a planing power boat, the system including a pair of rudder assemblies, each of which includes a rudder blade movably coupled to the hull by way of a ball-and-socket joint. Each rudder assembly includes a rudder shaft that extends from the rudder blade through the ball-and-socket joint and can be rotated for rotating the rudder blade to steer the power boat. Each rudder shaft may be operably coupled to a pair of actuators configured to control trim and camber positions of the rudder blade so that the pair of rudder blades can collectively achieve a desired hull trim change, including listing control and planing control of the power boat. Steering position, trim position, and camber position of the rudder blades may be simultaneously changed. | 03-06-2014 |
20140271122 | Rooster Tail Suppression Apparatus - A modifier may be used to prevent formation of a rooster tail when surface drive propellers are used with marine vessels. The modifier may be retractable by attaching it to the transom of the marine vessel or fixed-mounted by attaching it to the drive housing. The modifier changes the direction of the rooster tail so it flows substantially parallel to the surface of the water and hull of the marine vessel. | 09-18-2014 |
