  • Patent number: 5968656
    Abstract: In accordance with the present invention, an intermediate toner transfer member includes a substrate and an outer surface layer that includes a ceramer comprising a polyurethane silicate hybrid organic-inorganic network. The ceramer is formed by a crosslinking reaction between a polyurethane with reactive alkoxysilane terminal moieties and a tetraalkoxysilane. The silane-terminated polyurethane is the reaction product of one or more aliphatic polyols with terminal hydroxyl groups and an alkoxysilane-substituted alkyl isocyanate compound. Further in accordance with the present invention is a process for forming an intermediate toner transfer member having an outer surface layer comprising a polyurethane silicate hybrid organic-inorganic network.

  • Patent number: 5925256
    Abstract: The present invention concerns the treatment of an aqueous effluent and consists of ridding it of the iron which it contains, notably in the form of a complex. The method according to the invention consists of treating this effluent by successively a silicate, and a magnesium and aluminium hydroxycarbonate, then decanting and filtering. The method according to the invention is particularly useful in the treatment of photographic effluents.

  • Patent number: 5633125
    Abstract: The invention concerns a process for the selective extraction of the halide ions from photographic fixing solutions.The process consists of bringing the photographic fixing solution into contact with a liquid membrane comprising a solvent and a crown-ether carrier capable of carrying the halide ions from the fixing solution into an aqueous solution which is thus loaded with halides, and is then removed.

  • Patent number: 5496858
    Abstract: Aqueous disinfectant concentrate which includes succinic dialdehyde, glutaraldehyde and/or formaldehyde, one or more alcohols of limited water miscibility and optionally usual auxiliaries. By diluting with water, a working solution can be prepared from the concentrate. The advantages of the new disinfectant concentrate or disinfectant are the reduced development of odor, an improved material compatibility, an improved microbicidal effectiveness and a clearly increased storage-stability. Furthermore, the activation usual up until now with disinfectants based on aldehyde is superfluous. Preferred application fields are surface and instrument disinfection.
