Abstract: An electro-magnetic generator is disclosed, comprising a housing containing an arched array of metal coils and a magnet connected to a inverted pendulum. The inverted pendulum is configured to move the magnet relative to the bottom surface of the arched array of metal coils, generating an electrical current in one or more of the metal coils through electromagnetic induction. Each coil in the array includes a first terminal and a second terminal for electrical output. The generator further includes a plurality of current rectifier circuits, each connected to the first and second terminals of the respective metal coils, ensuring that the output current flows in a unified direction. The outputs from the rectifier circuits are summed together to create a combined current, which is routed to a battery terminal for storage. A voltage regulator is connected to the battery terminal to stabilize the electrical output.

Abstract: A resettable earthquake valve for gas lines, the valve having a housing with an external turn cock and an internal valve sleeve with a port that functions as a stopcock valve, the housing having an internal passage with a port and a closure biased valve disk displaceable from the port by a support member having an inertial mass, the support member being debilitated by a shock to the valve, the support member being connected to the biased valve disk at one end and engageable by a displaceable support base at the other, the valve having a cam mechanism for resetting the support member after being debilitated, for returning the support member to its support position displacing the valve disk from the valve port on resetting the valve.

Abstract: An improved integral opening and recapping device incorporated in the top of conventional aluminium top container constructed with an opening tab pivotally mounted to a pivot rivet centrally located on the container top, the tab having a detent edge engageable with a scored aperture flap for forced displacement of the flap to form an aperture, the tab having further a lever portion for operating the detent edge, the underside of the lever portion forming a sealing lip which on pivoting of the tab about the rivet, is engageable with the aperture to hermetically seal the container. The container top has a protective recess into which the sealing lip is nestled for protection of the lip from contamination prior to use.
