Patent GB-2032069-A (GB)
Title: Electrical primer
IPC: F42B3/182
Filed: 1979-09-19
Abstract: An electrical primer comprises a conductive pyrotechnical priming composition 3 placed in contact with a useful pyrotechnical charge 2 of the primer and two electrodes 6 and 7 in electrical contact with the conductive pyrotechnical composition 3. The resistance of conductive pyrotechnical priming compositions tends to vary with external conditions and time, so that primers employing such compositions tend to be of somewhat unpredictable performance. To alleviate this, a stable electrical resistance 10 is connected in parallel with the conductive pyrotechnical composition 3, between the two electrodes 6 and 7. The invention is applicable to the electrical ignition of pyrotechnical devices. <IMAGE>

Title: Logic electric networks
IPC: G06K15/10
Filed: 1980-03-25
Abstract: A matrix dot printer drive circuit 12 is supplied from a ROM 10 through a logic circuit which effectively extends the vertical array of the print out.
