  • Patent number: 7153446
    Abstract: A fire or explosion suppression system comprises a source (30) of a liquid suppressant under pressure, and a source (32) of an inert gas under pressure. The liquid suppressant is a chemical substance having a low environmental impact, with a short atmospheric lifetime of less than 30 days. The inert gas may be nitrogen, carbon dioxide, argon, neon or helium or mixtures of any two or more of them. The suppressant and the inert gas are fed under pressure to an output unit (34) comprising a mixing chamber in which the liquid and the gas impinge to produce a mist of the liquid suppressant of very small droplet size which is entrained in the pressurised gas together with vapour from the liquid, the so-entrained mist and vapour and the gas being discharged by a nozzle (44) into an area to be protected. The mist and vapour are therefore carried by the entraining and transporting high pressure gas into regions of the areas to be protected, enabling a total flooding capability.

  • Patent number: 7122100
    Abstract: A method for reducing the loss of particles from the surface of porous getter bodies is taught herein. The method consists in producing on the surface of the porous getter a thin layer of a metal or metal alloy with a deposition technique selected among the deposition of materials from arc generated plasma, ionic beam deposition and cathodic deposition. The deposition technique allows for granular or columnar surface of the covering material but still allowing access to the surface of the getter material, resulting in a reduced getter particle loss.

  • Patent number: 7091250
    Abstract: The present invention is an additive for producing a positive active material for lead-acid storage batteries on the basis of finely divided tetrabasic lead sulfate. The additive contains a tetrabasic lead sulfate of an average particle size less than about 3 ?m as well as finely divided hydrophobic silicic acid for preventing agglomeration of the particles of the tetrabasic lead sulfate. During maturation, this additive ensures the formation of the structure of a tetrabasic lead sulfate crystal with a very narrow bandwidth of crystal sizes and a very homogeneous distribution. In the subsequent electrochemical formation to lead oxide, this leads to particularly efficient lead-acid storage batteries. Furthermore, the invention relates to a method of making the additive according to the invention as well as its advantageous use in the positive material for the maturation and drying of plates in the production of lead-acid storage batteries.

  • Patent number: 7090787
    Abstract: A zeolite and an organic binder are mixed with a solvent to form a paste (302). The paste is then cast or molded (304) into the desired shape. A portion of the solvent is allowed to evaporate from the paste, hardening the getter (306). Getters are often formed in sheets and cut (308) into individual pieces, called dibs, after the sheets have hardened. Even after the getter is hardened, significant amounts of solvent are retained by the getter. The getter is exposed to water vapor which displaces (310) the solvent from the getter. After the solvent is removed, the getter is dried (312) to remove additional water vapor. Because the water vapor does not bind as tightly to the zeolite getter, the water vapor is removed much easier than the solvent. The water may be removed by allowing the getter to dry naturally, or by a vacuum bake process.
