Abstract

1526308 Bird scares AGRICAID Ltd 31 Jan 1977 [28 Nov 1975] 49016/75 Heading A1E [Also in Division H3] A bird scarer emits bangs at irregular intervals. A pseudo-random electronic timer energises an electromagnet 25 at irregular intervals of between 20 seconds and 40 minutes, causing a lever 28 to actuate a valve 5 to admit propane gas to the cylinder 8 of a single-acting piston. The piston is thus extended, pivoting a lever 40 against spring bias, and at the end of its stroke returning lever 28 to its initial position and thus actuating the valve 5. Gas is thus expelled from the cylinder 8 by the spring return of the piston and passes to an explosion chamber 3. Release of the lever 40 by the piston causes actuation of a piezo-electric igniter 13 producing a spark in the explosion chamber. A photoelectric cell disables the timer at night.
