Abstract: An electric controller for selectively activating a plurality of solenoid water valves in a irrigation system and on a pre-selected recurrent time basis. The controller features a molded chassis and a printed circuit board construction to provide a more rugged and simplified unit as compared with the prior art controllers of the same general type.
Abstract: A time switch having two scale disks rotating at different speeds. A program, set by projections, on the faster disk can be cancelled by like projections on the slower disk. Levers contact the respective disks and, directly or indirectly, contact on one side a common lever that actuates the plunger of a switch. Additional manual means are provided for positively actuating or deactuating the switch, by holding some of the levers at fixed positions.
Abstract: The apparatus may be embodied as a self-contained unit associated with the television set or integrated into the television set. The control is basically in two functions, one which is set for programming the availability of use of the television set at predetermined time intervals of the day, and the other which is set for controlling total usage of the television set over a given period such as a 24-hour period. In the preferred embodiment the two functions are set and repeated automatically every day. In another version different settings are allowed for both control functions for weekdays and weekends. In still another version each day of the week may be set separately with regard to both control functions.
