Title: Production of copper compounds.
Inventor: BROWNE CHRISTOPHER JOHN
IPC: C01G3/14
Filed: 1990-08-01
Abstract: A method of producing copper compounds involves contacting metallic copper with oxygen or an oxygen-containing gas, with an aqueous solution consisting essentially of water in solution in which is a soluble ammonium salt NH4X, where X is the anion of the salt, and with ammonia in an amount such that the solution is initially alkaline. As a result of such contact the metallic copper is initially dissolved to form a copper ammine Cu(NH3)4X and the formation of the ammine continues until the saturation concentration of the ammine is reached. Subsequently, the ammine continuously breaks down to form 3Cu(OH)2.CuX2 and the water soluble products of the ammine decomposition continuously reform the amine by further reaction with the metallic copper and the oxygen on oxygen-containing gas.

Abstract: A novel bottle crate is described which has at the sides (3) self-supporting carrying handles (9) which are formed by the gripping openings (8) leading in each case at one end up to the top edge of the crate. Both the self-supporting carrying handles (9) and the adjoining wall parts (6) are expediently formed from hollow profiles. Further hollow profiles (6, 11) form end-side carrying handles (10) and lead to the crate bottom (1, 2) so that, in total, a combination of hollow profiles allows high rigidity and strength with low weight. The self-supporting carrying handles (9) result in very good carrying convenience. Additionally, a further inside carrying handle (13) may be provided which connects the free ends of the self-supporting carrying handles (9) to one another. As a result, the strength is further increased and the crate can be carried without great inclination and thus with good clearance above the ground. <IMAGE>

Abstract: A multistage amplifier for amplifying an input signal so as to output an amplified signal. The multistage amplifier is comprised of a plurality of transistors that are monolithically formed around a central VIA hole. Predetermined electrodes of the respective transistors are electrically connected to each other in the area immediately surrounding the central VIA hole and are connected to the VIA hole itself. This allows for a reduction of the number of VIA holes used over conventional methods. The distance between the central VIA hole and the predetermined electrodes of each of the transistors is minimal, as is the wiring pattern of each of the electrodes. No scattering is caused by the characteristics of the transistors, as they are monolithically formed in the same manufacturing process.
