Abstract: A circuit breaker is configured to be remotely caused to enter ON and OFF states. A lever arm is pivotably coupled to a main contact spring. A contact is supported at the distal end portion of the lever arm. Pivoting of the lever arm to bring the contact into contact with another contact on the housing causes the circuit breaker to enter the ON state. Pivoting of the lever arm to separate the contacts causes the circuit breaker to enter the OFF state. A latching solenoid includes a plunger coupled to the lever arm. The latching solenoid moves the plunger between a retracted configuration and an extended configuration. When in the extended position, the lever arm is pivoted to separate the contacts to cause the circuit breaker to enter the OFF state.

Abstract: A nursery box comprising a growth substrate for rice, rice seeds and an aqueous formulation for treating said rice seeds to protect rice plants against insects for a prolonged period of time.

Abstract: Process for treating rice plants or rice propagation material against insects with a view to obtaining sustained and effective protection of the plant after the sowing period, characterized in that there is applied to the said plants or to their propagation material an effective amount of an insecticide other than an organophosphorus insecticide having systemic properties which is capable of having a long-lasting effect, that is to say even persisting on the growing plant after germination.This process is used with a pyrazole insecticide.The invention also applies to the seeds thus treated and to the nursery boxes containing them.
