Abstract: Methods and systems for providing improved audio environments in relation with gaming systems are described. According to one embodiment, a gaming system comprises a gaming device comprising sound producing components and a sound processing system for transmitting sounds to a player based on sounds produced by the components. The sound processing system comprises a microphone; filtering means filtering the audio signal resulting from the sound capture; and outputting means outputting an audio environment based on the filtered signal. Therefore, the system provides, in real time or with a non-perceivable delay, an improved audio environment reflecting an outcome generation process. In another embodiment, a method is described comprising the steps of capturing outcome generating sounds in a signal, filtering it, and outputting an audio environment accordingly, wherein the method is performed in real time or with an non-perceivable delay.

Abstract: The conservation of water is an issue that preoccupies an increasing number of people. Among all domestic appliances, toilet is an appliance that consumes an appreciable quantity of water. The present invention provides a dual flush system that allows to select the volume of water when using a toilet by choosing between two volumes of water.

Abstract: Disclosed is a process for treating waste sulfuric acid generated from a process for producing titanium dioxide pigment by treating titanium slag with sulfuric acid. The waste acid is treated in a first step with a calcium-containing material to produce a gypsum suspension which is filtered and from which a filtrate is recovered. The filtrate is treated in a second step with a calcium-containing substance and clarification solids from the treatment of the titanium slag with sulfuric acid. A precipitate is produced in this second step which is subsequently filtered. The precipitate is suitable for disposal in a landfill.
