Title: Improvements in and relating to high tension electrical supply for wireless apparatus
IPC: H04B1/16
Filed: 1928-02-27
Abstract: 311,849. Milnes, H. R. Feb. 27, 1928. Charging and discharging batteries.-High-tension secondary batteries for use with wireless apparatus are charged by a secondary battery of different type and slightly higher voltage, the charging continuing until a state of balance is reached with the voltages of the batteries equal. A high-tension battery of nickel-iron cells may have its cells connected in paralleled groups of four to a 6-volt lead accumulator used for the filament supply. The lead accumulator discharges at uniform voltage, and the voltage of the nickel-iron cells rises steadily during charging until the balance is reached with the cells charged. The lead accumulator may be periodically charged from the mains, a charger and switch being added to the apparatus and a resistance being connected between the lead accumulator and the high-tension battery so that the charger current flows mainlv to the lead accumulator. Groups of nickel-iron cells C in a frame F are connected to contacts C<1>, C<2> co-operating with longitudinal contact bars S<1>, S<2> and cross-pins S<3> on a rotatable switch S, the bars S<1>, S<2> connecting the groups in parallel to the lead accumulator for charging and the pins S<3> connecting the cells, disconnected from the accumulator, in series for use. The contacts C<1> are pressed down by the lid L and some are connected to tappings P. The cells C have glass wool W at the bottom or are entirely packed with the wool. Oil 0 is placed on the electrolyte and the cells may have a rubber sealing-cap. Rubber bands R act as distance-pieces. The contacts C<1>, C<2> are held in rubber tubes T between metal and wood bars T<1>, T<2>. The Provisional Specification describes also a rubber cell-sealing cap pierced to form a gas valve, a series-parallel switch comprising a sliding plate operated by a lever, and a circuit in which the voltage of the low-tension accumulator is modified, by a series cell of another type or otherwise, to produce the correct charging voltage.
