Abstract

1,025,397. Stage lighting systems. ALLMANNA SVENSKA ELEKTRISKA A.B. Feb. 4, 1963 [Feb. 5, 1962], No. 4407/63. Heading H2H. The lamp group 1 of a stage lighting system is fed from taps on auto-transformers 3, 3<SP>1</SP>, which are energized from a dimming device comprising a potentiometer 4 whose sliding contact 5 varies the ratio of the voltages applied to transformers 3, 3<SP>1</SP>, movement of the contact 5 to an end position to shortcircuit the transformer 3 or 3<SP>1</SP> causing closure of contacts 2 or 2<SP>1</SP> to short-circuit the secondary side of the short-circuited transformer, whose tap setting may then be altered without disturbing the lighting system. Fig. 2 shows an arrangement in which the light group 1 is connected to transformers 3, 3<SP>1</SP> through binary relay systems 7, 8, 9 and 71, 8<SP>1</SP>, 9<SP>1</SP>, which may be controlled in a predetermined sequence by a press-button contact system 12<SP>1</SP> or by a system 12 comprising a pivoted arm 121 movable to cause its contacts 125 to bridge contacts 122, 123 connected to the relays. Alternative control of the relays is provided by contacts 10, 10<SP>1</SP>. The light group 1 may be connected to the supply 6 through rheostats 11, 11<SP>1</SP> instead of transformers 3, 3<SP>1</SP>, each rheostat being common to several circuits, if desired. The rheostat 11 may be remotelycontrolled by the arm 121 through a potentiometer 124 incorporated in the contact system 12 and connected to the terminals 115, 116 of rheostat 11. By suitable dimensioning, a setting of potentiometer 124 will correspond to that of the relay system 7, 8, 9 and contact system 12, and thus a desired setting for this system may be made through potentiometer 124 with contacts 10 open, subsequent closure thereof switching the light group 1 from the rheostat 11 to the transformer 3. Automatic control of the relay system 7, 8, 9, may be achieved by recording a desired lighting sequence with terminals 14 connected to the punch apparatus of a punch-card system, and then connecting these terminals to the reading contacts of the system when reproduction is required. Such an automatic programme may be interrupted by opening contacts 10 and transferring to the manually-controlled system 12. The dimming device 4 may also be automatically controlled through a punch-card system.
