Abstract

1,171,914. Lighting control systems. THORN ELECTRONICS Ltd. 19 Oct., 1967 [21 Oct., 1966], No. 47340/66. Heading H2H. [Also in Division G3] The Specification relates to lighting control systems generally similar to those described in co-pending Specifications 1,171,915 and 1,171,916, but is primarily directed to the layout and functioning of the channel selector and the input scanner. As shown, the selector 13 comprises a " hundreds " register 50 and a " tens " register 51, both of which can be set by push-buttons (not shown) and which are connected to corresponding AND gates in respective matrices 52, 53, each gate also receiving an input from the corresponding " hundreds " and " tens " outputs of the divider circuit 16. The output 54, 55 of the matrices are connected to an AND gate 56 in turn connected to all the AND gates in the matrix 58 of the input scanner 22, each of the latter gates also receiving an input from a fader and an input from the unit register of the divider 16. Thus the fader outputs appear at terminal 59 for the range of channels selected by selector 13, the matrix 58 being duplicated to provide two output terminals respectively supplying " raise " and " dim " analogue signals from the faders. The channel selector may be modified according to the number of faders provided in the system, e.g. the channel selector may have " hundreds," " tens " and " units " if only one fader is present. Operation of the system for various numbers of faders is discussed. If a greater number of channels are required, the divider and channel selector are modified together with an increase in the master oscillator frequency or the time of the divider cycle. The Specification also describes an AND gate matrix, Fig. 4 (not shown), suitable for the file selector (35) of the lighting control system of Specification 1,171,916.
