Abstract: Systems and methods of operating a wheel are described herein. The wheel includes a plurality of game wedges and a wedge selector. The plurality of game wedges includes a first variable wedge, a second variable wedge, and at least one moveable wedge. Each game wedge is associated with a respective award and a respective probability of selection. The method includes generating, using a random-number generator, a random number representing a selected game wedge of the plurality of game wedges, causing the wedge selector to visibly identify the selected game wedge, and in response to a trigger game wedge of the game wedges being the selected game wedge, shifting the moveable wedge around the wheel to change a visible size of the first variable wedge and the respective probability of selection of the first variable game wedge proportional to the change in visible size.

Abstract: Bent and/or toughened silver coated glass having light transmission is produced by depositing layers of additional metal over, or both under and over, the silver layer. When the additional metal is used over the silver layer, it is selected from aluminium, titanium, zinc and tantalum. When the additional metal is used both under and over the silver, it is selected from aluminium, titanium, zinc, tantalum and zirconium. The additional metal is used in an amount such that the light transmission of the coated glass increases on bending and/or toughening. The bent and/or toughened coated glass is useful for architectural glazing and as vehicle windows.

Abstract: A bent and/or toughened coated glass is produced by subjecting glass having a coating comprising at least one metal having an atomic number of 22 to 29 and a thin layer of aluminum applied over said coating to a bending and/or toughening cycle in which the coated glass is heated to a temperature above the softening point of the glass.The invention is useful for the production of bent and/or toughened solar control glasses, low emissivity glasses (when the metal used is copper) and mirrors.

Abstract: Bent and/or toughened silver coated glass having high light transmission is produced by depositing layers of additional metal over, or both under and over, the silver layer. When the additional metal is used over the silver layer, it it selected from aluminium, titanium, zinc and tantalum. When the additional metal is used both under and over the silver, it is selected from aluminium, titanium, zinc, tantalum and zirconium. The additional metal is used in an amount such that the light transmission of the coated glass increases on bending and/or toughening. The bent and/or toughened coated glass is useful for architectural glazing and as vehicle windows.

Abstract: A surface of a hot ribbon of glass, which has just been formed, is coated by directing a flow of coating gas substantially parallel to the glass surface under laminar flow conditions. The laminar flow is in the direction of ribbon advance or co-current to that direction, and the gas is released uniformly across the width of the ribbon. The coating gas contains a constituent, for example a silane, which decomposes on the hot glass surface to deposit a coating, for example silicon, on the glass surface.
