Abstract: A water turbine propeller includes an optional turbine casing having forward and rearward openings, a rotational cylindrical unit, a plurality of rotating foil blades rigidly secured to the inner periphery of the rotational shaft on a common shaft, and an engine or motor which rotates the rotational shaft within the turbine casing. The operation of the engine causes the rotation of the rotational shaft and the helical blades direct water into the forward opening of the turbine casing and out the rearward openings of the turbine casing, thereby creating a focused torque (or vortex) effect on the water flow for a propulsive force.

Abstract: A computing system is able to modify one or more settings controlling the operation of an interactive application system. The interactive application system is configured with a plurality of accounts to enable, at least, attribution and authorization by the interactive application system of interactions with the interactive application system. One or more settings control the operation of the interactive application system with regards to the interactions and the accounts. The computing system is configured to receive a plurality of inputs in relation to a first setting of the one or more settings, the inputs being associated with different ones of the plurality of the accounts. The computing system then correlates the plurality of inputs and modifies the first setting in dependence on the correlated inputs.

Abstract: There is provided a hair treatment applicator (1) for applying a hair treatment product to hair. The applicator comprises: a handle (2) comprising a first extremity and a second extremity; and a first retaining structure (3a) and a second retaining structure (3b) for receiving, retaining and spreading said hair treatment product, both retaining structures being connected to said handle. The first retaining structure and the second retaining structure are located at the first extremity and the second extremity, respectively, and the retaining structures are different from one another.

Abstract: A method and apparatus for predicting the result of the coloration of a substrate by a coloring product. The method and apparatus involve the use of micro-processing system and are especially suitable for quickly and easily determining the result of hair coloration by a commercial hair dye product. Preferably a bar-code scanning device is used to input information relating to the product into the micro-processing system.
