Abstract: PURPOSE: To prevent the contamination of filtered water by relatively thickening a sand layer and jetting pressurized water from upper side in addition to reverse wash and jet flow stirring of the sand layer.  
     CONSTITUTION: A sand layer 11 is disposed above a porous plate 12. Under the plate 12 there is provided a closed conduit 13 for collecting purified filtered liquid. Feed water is supplied to a supply closed conduit 14 as shown in an arrow A, and introduced through an opening 16 into a small chamber 10, i.e. filter cell. During the passage through the sand layer 11, suspended matters are catched by sands, and purified water is introduced into the closed conduit 13 and passed through a outflow pipe 17 into a closed conduit 15 for the purified water. A pump P 1  is suspended from a support 20 into the closed conduit 15 for the purified water, sucks the filtered water through a first change-over valve 21, and pressure-feeds the filtered water to the closed conduit 13 by means of a second change-over valve 22. The filtered water is jetted through the porous plate 12 into the sand layer 11.

Title: Sealed lead-acid battery
Inventor: SAWAI KEN
IPC: H01M2/16
Filed: 1993-03-25
Abstract: PURPOSE:To improve charging/discharging cycle life of a sealed lead-acid battery for absorbing oxygen gas formed during charging into a negative electrode, by using a positive electrode lattice consisting of a lead-antimony alloy, and by providing an organic high polymer having an ion exchanging functional group between a positive electrode plate and a negative electrode plate. CONSTITUTION:The diameter of the primary particle of silica very fine powder used for an electrolyte holder is 10-40nm, and the surface area is 20m<2>/g. A powder-form cation exchange resin of 200-400 mesh is used as an ion exchange resin, and the capacity of the exchange group of the resin is no less than 4.4meg/g-R. The lifetime is thus extended while the current decreasing is reduced. Since a lead-antimony alloy is used for a positive electrode lattice, degradation of positive electrode active material and the extension of the lattice are expected to be reduced. The movement of antimony from a positive electrode to a negative electrode is considered to be inhibited by the ion exchange resin. In the diagram indicating the result, the curves 1-3, of the curves indicating transition of discharging capacity and transition of the amount of reduced liquid, indicate the characteristic of the battery used.
