  • Patent number: 10355435
    Abstract: The present invention, relates to an improved mobile cell-phone charger device, a wireless USB male prong plug, to charge a plurality cell-phones or tablets apparatus members. One of the embodiment features of the present invention, pertains to a revolving pivot pinion wheel, which rotates in a clockwise or counterclockwise movement, inside the casting frame member, charging a cell-phone member. This improved mobile cell-phone charger device, consist of an electrical female prong connector holes, attached to a revolving pivot pinion wheel, to charge multiples different cell-phones apparatuses members. The universal multi-charger device, has others improved features, such as a rotating dial member, to control and charge different cell-phones apparatuses members.

  • Patent number: 5482199
    Abstract: A one handed soldering tool incorporating a heated tip configured with one or more solder retaining recesses therein. Adjacent this heated tip is an end region of a solder supply conduit through which a solid wire solder passes. During operation, as the heated tip is heated, the adjacent end region of the solder supply conduit is likewise heated. Such heating will melt the wire solder therein thereby causing it to flow out of the conduit and into the recesses in the heated tip. This collection of melted solder can then be used to attach a workpiece in place as desired. Consequently, the user is able to support this workpiece during such operation since the step of continuously biasing the solid solder against the heated tip has been eliminated due to the collection of the solder stored in the solder retaining recesses of the heated tip.

  • Patent number: 4521965
    Abstract: A can opener for opening cylindrical metal cans by means of a reciprocating, circular motion produced by holding the can opener in the hand of the user and moving it up and down while also rotating it about a vertical axis. The can opener includes a handle at its upper end on a hollow, cylindrical shaft which includes at its bottom end a series of, for example, four radially extending arms having at their distal ends downwardly pointed, "V" shaped blades having sharp tips, and a smaller, spring-bias shaft which telescopically fits into the main shaft and which has at its lower end a magnet. The ends of the cutting blades also preferably include inverted "U" shaped hooks which engage and hold the upper, vertically extending peripheral lip of the can during the cutting operation. The cutting blades telescopically fit into the radially extending arms, so that they can be easily removed and replaced with cutting blades that provide a different effective diameter of cutting action for different sized cans.
