    摘要： There is provided a regulator for wall thermostats. The regulator is operated by a timer, and provides a warm air stream upwardly beneath a thermostat to cause the thermostat to lower the house temperature between specific hours, such as at night, and cuts off the warm air stream for the remainder of the day. A housing defines an air passage which has manual means for restricting it to a greater or lesser degree. Illumination and heating means are provided within the housing which simultaneously heats the air to promote convective flow upwardly, and illuminates the manual means.

    摘要： An electrical protection system, which can be connected between an electrical power supply and an electrical load, firstly includes a switch switchable between a normal state in which the switch is electrically connected in series between the power supply and the load such that an operating current passes through the switch and the load, and a fault sate in which the switch is disconnected with the load such that no current passes through the load. The switch switches to the fault state in an over-current or an over-temperature situation. The system further includes a controller operable in an open state when the switch operates in the normal state, in which state the controller is electrically disconnected from the power supply such that no current passes through the controller, or a closed state when the switch operates in the fault state, in which state the controller is electrically connected in series between the switch and the power supply such that a self-holding current passes through the switch and the controller. The controller operates to automatically set the switch to the normal state when the self-holding current is off.
