Abstract: The present invention relates to a process for the preparation of aromatic azo-compounds, in particular 3,3′-azo-bis(6-hydroxybenzoic acid) (olsalazine) and its salts and derivatives.

Abstract: A modular jack electrical connector assembly 2 suitable for conditioning the signals in unshielded twisted pair wires for use with network components is disclosed. The modular jack 2 comprises a conventional insulative housing 4 and an insert subassembly 6 including an insert molded front insert member 8 and a rear insert member 10. Contact terminals 12 for mating with a modular plug extend from the front insert member 8 and into the rear insert member 10. The rear insert member 10 also includes signal conditioning components such as common mode choke coils 38, filter circuits 40 and transformers 54 suitable for conditioning the twisted pair signals for used in applications such as for input to and output from IEEE 10 Base-T network components.

The insert molded body 30 of the rear insert member encapsulates the signal conditioning components to protect the components and to stabilize the component to achieve reliable repeatable performance.

Abstract: Nitrogen oxides and carbon monoxide are removed from the exhaust of an internal combustion engine which operates on a methane-containing fuel by reacting the carbon monoxide, nitrogen oxides, and oxygen in the exhaust gas with methane in the presence of a catalyst comprising a crystalline zeolite having a silicon to aluminum ratio of equal to or greater than about 2.5 which is exchanged with a cation selected from the group consisting of cobalt, nickel, iron, chromium, rhodium, gallium, and manganese. Methane for the reaction is provided as a portion of the methane-containing fuel.
