Abstract: In the production of nitrated aromatic compounds by reacting an aromatic compound with nitric and sulfuric acids, the NOx gases produced are contacted with water to produce weak nitric acid which is recycled to the process. Aromatic compounds are continuously nitrated by: (a) introducing the aromatic compound, nitric acid and sulfuric acid into a nitrator; (b) reacting under controlled conditions to produce a nitrated aromatic compound and NOx gases; (c) separating the NOx gases; (d) contacting the gases with essentially pure water under an elevated pressure to form weak nitric acid; and (e) recycling the nitric acid for reuse in the process. An independent claim is also included for a nitration system comprising a nitrator including: (i) feeds for aromatic compound, sulfuric acid and nitric acid; (ii) a separator for separating spent sulfuric acid from the nitrated compound; (iii) a separator for NOx gases; and (iv) a contactor for contacting these gases with water.

Abstract: An electrically heated laminated window (1) is disclosed in which an array (2) of heating wires (3) is embedded in an interlayer material (23) extending between inner and outer panes (22, 21) and connected to a voltage supply by bus bars (6, 7, 8, 9) in the form of tinned copper strips. At least one face of a bus bar in contact with the heating wires is coated with a low melting solder and that bus bar face is also coated with a halogen-free flux prior to application of the solder. The use of a halogen-free flux avoids corrosion of the heating wires in the vicinity of the heating wire/bus bar joint, thereby reducing the likelihood of inoperative heating wires and increasing the durability of the heating circuit. Such heated windows are used especially in vehicles.

Abstract: Bus member addressing method in which if a bus member detects a power drop it switches off its switch (26). A temporally defined slow switching on of switched current sources then takes place sequentially within a group of bus members. The last bus member has a detector that detects when no current is present, so that after a defined time period this switch is still open. Thus one member of a member group is specified and can have an address assigned to it. In further address cycles, other members are assigned addresses in a similar manner. Independent claims are also made for three further bus member addressing methods.
