| Number | Title | Issue Date |
| 4525327 | Lead-antimony-magnesium alloys for storage cell supports and method of manufacturing said alloys A lead based alloy for electrode supports of a lead-acid storage cell, the alloy containing between 0.05% and 4% antimony between 0.02% and 0.3% magnesium, and no barium. The magnesium permits a reduced antimony content, thereby reducing the corrosion, se... | 06/25/1985 |
| 4476206 | Fiber reinforced grid for a storage cell, and method of manufacturing it A grid (10) for the plate of an electrical storage cell, eg. a lead-acid accumulator, comprises two orthogonal sets of conductive bars (7, 8) together with a current collector tab (9). The grid is made from a loosely-woven cloth comprising both bundles of... | 10/09/1984 |
| 4346153 | Electrode for a lead-acid storage cell An electrode for a lead-acid storage cell, electrode containing an active material (8), an active material support and at least one electric conductor which includes a core (10) made of a metal whose electric conductivity is higher than that of lead. Said... | 08/24/1982 |
| 4253871 | Alloys for making electrode supports in lead accumulators Low antimony alloys of lead are used for casting electrode supports in lead accumulators. They include less than 4% antimony by weight to avoid various poisoning effects of antimony on the electrochemical processes involved. Such alloys tend to have grain... | 03/03/1981 |
| 4206273 | Protector for a battery strap The protector has two ends connected to a central portion, these ends being hollow and each suitable for covering one of the two terminals of two contiguous cells of the battery, the central portion being hollow and being able to cover the connection or s... | 06/03/1980 |
| 4131723 | Lead storage battery with limited evolution of gas A maintenance-free lead storage battery comprises a container closed by a lid and containing an acid electrolyte together with a block of positive plates, negative plates and separators. The block of plates and separators is tightly packed in a case which... | 12/26/1978 |
| 4053824 | Method and device for checking a storage battery A battery of series-connected storage cells is checked by: Measuring the transient elementary open-circuit voltage at the terminals of each storage cell; Comparing the said elementary voltages with the average transient voltage of the said storage cells (i.e. ... | 10/11/1977 |
| 4044300 | Method for checking a storage battery A method of checking a storage battery with series-connected cells comprises the steps of: Passing a charging current pulse through the battery, Measuring an elementary transient voltage at the terminals of each storage cell; and Comparing elementary transient... | 08/23/1977 |
| 3940536 | Mechanically reinforced high porosity partially fused glass fiber galvanic separator A separator for a galvanic element wherein partially fused glass fibers are coated by a coating consisting of grains of thermo-hardening synthetic material immersed in a natural or synthetic latex to mechanically reinforce the knots in the glass fiber net... | 02/24/1976 |
