Abstract: In a current overload protection circuit, a full wave rectifier bridge circuit is connected between an AC or DC power source to supply AC or DC power to a load through the output circuit of a solid-state relay. A current sensing resistor is connected across the DC terminals of the bridge circuit to sense the magnitude of the current flowing through the load. When an overload fault occurs, the voltage developed across the current sensing resistor will trigger a shunt regulator to turn on an optical isolation circuit, which upon being turned on will discharge a capacitor in an RC timing circuit. The discharge of the capacitor and the RC timing circuit triggers a Schmidt trigger circuit, which cuts off current flow to the input circuit of the solid-state relay, thereby cutting off current to the load. The shunt regulator then turns off de-energizing the optical isolator which, upon being de-energized, causes the current discharge path of the capacitor to be interrupted.

Abstract: A barrier for the protection of reserved areas including at least one upper element (1) rotatably mounted relative to a lower element (6) anchored in the ground (G). An elastic return spring (18) is interposed between the upper and lower elements (1,6). The upper element (1) is adapted to be displaced to either side of an upright reference position by rotating about a horizontal pin (2) provided on the lower element (6). A releasable mechanism selectively blocks rotation of the upper element in a first direction (F2) and a non-releasable mechanism blocks rotation of the upper element in the reverse direction (F1) at the end of a limited angular deflection. The elastic return spring provides a force opposing the limited deflection in the reverse direction.
