Abstract: Liquid aqueous bleaching compositions are disclosed which comprise hypochlorite and a specific complexing agent or mixtures thereof selected from the group consisting of polycarboxylic acid derivatives of pyridine or the salts thereof. The compositions have a pH from 11-14 and preferably further comprise a calcium/magnesium precipitation system. The complexing agent counteracts the adverse affect which certain metal ions have on fabric strength and fabric color when hypochlorite bleaches are used in the presence of said ions.

Abstract: The invention concerns a system for transmission of spatial diversity radio signals via a geostationary main communication satellite and one or more auxiliary satellites "colocated" in the same orbit. The distance between an auxiliary satellite and the main satellite is in the range from 200 km to 400 km. The system includes conventional bidirectional transmission links between terrestrial mobile terminals and the main satellite and between the latter and a terrestrial station. Additionally, unidirectional transmission links are provided between the auxiliary satellites and the main satellite. Applications include a mobile communication service with portable terminals via a geostationary satellite.
