Abstract

445,708. Batteries. STONE & CO., Ltd., J., Deptford, and CHILTON, A. H., 200, Brompton Road, Chelsea, both in London, and SCHOFIELD, W., 7, Dynevor Gardens, Leigh-on-Sea.. Oct. 16, 1934, No. 29597. [Class 53] [See also Group V] An accumulator plate consists of a number of perforated or porous tubes 3 which are provided with inner tubular sheaths or linings 7 within which the active material 1 is contained. The linings 7 are made of fibrous material such as glass wool or nitrocellulose, and the active material surrounds rods 2 connected to bars 5, 6. The tubes 3 may be made of ebonite and may be provided with ribs 4, and the area of the perforations in the tubes may be from 28 to 35 per cent of the surface of the tubes. In one method of making the plate the tubes 3 are first assembled on the bottom bar 6 and around the rods 2. The linings 7 which may be cemented to tubular form are then placed in position in the tubes and powdered active material is dropped into the spaces between the linings and rods 2. The structure is vibrated to pack the material in place and when the tubes are full the bar 5 is secured to the rods 2. In another method of making the plate a paste of red lead and sulphuric acid is filled into semi-cylindrical recesses 9, 10 in the two halves 11, 12 of a mould, Fig. 4. A rod 2 is supported at its ends in recesses 13 in the mould part 11 so that the rod extends axially along the cylinder formed by the recesses 9, 10. The two parts of the mould are then placed together and subjected to pressure. Pins and holes 14 ensure registration of the two mould parts. The pencil of active material surrounding the rod 2 is then removed and dried. A sheet of glass wool may then be wrapped cylindrically round the pencil, or a tape of glass wool may be wound helically round the pencil. The covered pencil is pushed into a tube 3 which is immersed for some days in dilute sulphuric acid and then dried. The plate is then built up from a number of pencils and tubes so produced.
