The invention relates to a process for cooling gases using a circulating fluidized bed technique, wherein gas is conveyed through a fluidized bed formed by circulating fluidized bed material so that part of the circulating fluidized bed material is driven along with the gas flow and whereby the circulating fluidized bed material entrained in the gas flow is separated from the gas flow and returned...

The appts. forms areas of modified optical properties in a layer. The layer (3) is heated locally to a point beyond the write temperature by a radiation beam (107a) whose power is adjusted in a pulsating pattern. A signal indicates the forming-speed of the area affected and is derived from radiation reflected from the layer. The measurement circuit (50) includes an adjustment circuit including a c...

A leadfree plate-shaped roof flashing material comprises a sandwich structure in which a stress damping and stabilizing layer (1) of ductile material is completely covered on one side and at least partly covered on the other side by preferably metallic foil sheetings (2, 3), e.g. of aluminium foil, designed with densely positioned flattened folded sections (4) having such a form, e.g. as closed in...
