Abstract: An electrical energy supply indicator for a helmet is disclosed to employ a casing having a storage chamber for housing an electrical resistor, a light-emitting diode (LED), a cover plate, a female terminal socket; wherewith the storage chamber has a compartment plate, the female terminal socket has an article locking member, a pin receiving member having four trapezoidal faces, an anode and a cathode for connecting with the resistor and LED. The locking member is immobilized between the compartment plate and an interior surface, the receiving member passes through the receiving channel to connect externally with a male terminal pin. The LED operates to determine if attached electrical circuit is powered. A slant-faced extrusion block is on the underside of the cover plate to superimpose onto the locking member such that the locking member can be more secured inside the casing, thereby preventing undesirable movement of the female terminal socket.

Abstract: A method for manufacturing hose couplings is composed of three steps as follows. The first step involves jointing and fixing a top casting-cavity insert and a bottom casting-cavity insert within a mold base of a casting machine. The second step is injecting a high-temperature molten metal into both the casting-cavity inserts, so that the molten metal can fill up the casting-cavity inserts. The third step is cooling the casting-cavity inserts by using a cooling liquid, so that the cooled and solidified metal can be released from the casting-cavity inserts to form a hose coupling. By using the method, various types of top casting-cavity inserts and bottom casting-cavity inserts may be adapted as desired and, therefore, various types of hose couplings may be manufactured as desired.
