Title: Dimming circuit for high pressure gas discharge street lamp - has relay to switch alternative combinations of capacitance and inductance
Inventor: LOEF CARL
IPC: H05B41/04
Filed: 1980-04-02
Abstract: The dimming system for high pressure gas discharge street lamps, to save power, uses a choke coil (L) with a centre tapped winding and a series capacitor (C1) in series with each lamp (Lp1). A switch also in series with the lamp is operated by a relay (Rel1) connected at one end to a control line and at the other end to one side of the mains connection. This switches a capacitor (C2) in parallel with the lamp across the two mains connections, and by-passes the series capacitor and also one section (L1) of the choke winding. Alternative circuits include a circuit with a relay which simply connects a capacitance in series with a choke coil with a single winding and in series with the lamp, to dim it. In normal operation, there is only the choke in series with the lamp. Another circuit switches out one of two parallel chokes and switches in a series capacitance.

Filed: 1980-07-05
Abstract: The punching tool (1) is fitted on a swivelling lever (5) with a pivot (13) on the holding-down device (14) of the press. During the downwards movement of the ram the holding-down device (14) has a forward slip in relation to the tool upper part (10) until the centering tip comes to rest on the appropriate point of the workpiece. A further downward movement of the upper part (10) carries out the punching action by means of pressure cam (15) and swivelling lever (5). When the swivelling lever (5) moves, so does the punching tool (1) carrying out the punching on the workpiece (3). The pressure cam (15) and/or the adjoining surface (16) are curved, so that the two surfaces roll or glide over each other. After completed punching operation the return stroke of the ram begins and a plastic sleeve (20) ensures the slipping-off of the workpiece from the punching tool (1).
