Abstract
1,072,773. Photo-electric control systems. C.A. DE LA CHEVRELIERE. July 10, 1964 [Oct. 22, 1963], No.28661/64. Heading G1A. To control a sprinkling or irrigation device a photo-sensitive device 3 is positioned in a box 1 having a slot 2 in the opposite wall. The box is mounted for angular adjustment on a stand 9 and is so positioned that it is possible for direct sunlight to fall on the device 3 for a suitable period during the day, preferably when the sun is low. When sunlight does pass through the slit and fall on the cell it causes a relay 5 to be energized controlling electromagnetic valve 6 in the pipeline 7 to the watering system. The period of time during which sunlight can operate the system depends on the width of the slot 2. The effective width of this can be varied by means of a screen hinged to the front of the box and capable of being locked in a desired angular position or by a sliding shutter movable partially over the slot. A filter 14 may be placed in front of the cell 2 or the relay arranged to function only when the light intensity is above a given value. Preferably the dimensions of the arrangement are chosen to prevent any chance of the system being actuated when the sun is high.
