Abstract
The present invention is an electrical device that can seal an array of glass ampules and micro ampules using plasma arc produced by electricity. The device can produce high temperature by making mini plasma arcs which will melt down the glass and make a permanent seal. The arc is produced in a sealing head which covers the plasma arc and can focus the heat in a very small area so that the heat can be directly transferred to the glass without any intermediate, thereby increasing the efficiency. The plasma arc can increase the heat by using multiplication of the arcs encased in the sealing head.
Claims16
1) A glass sealing device, comprising:
- a) a tray to receive and hold one or more glass ampules;
- b) one or more sealing heads to seal said one or more glass ampules, each sealing head is:
- i) a closed top head or an open top head, wherein the closed top head has a bottom cavity configured to receive the top head of each glass ampule, and the open top head is a two piece head each having a side cavity, wherein the top head of each glass amplue is placed in between said side cavities;
- ii) a set of conductive wires passed through each sealing head to form a set of electrodes in the bottom cavity of the closed top head or in the side cavities of the open top head;
- c) a power source to generate a set of plasma arcs between each pair of electrodes across the bottom cavity or side cavities to heat, melt and seal the top head of each glass ampule.
13) A glass sealing device, comprising:
- a) a chamber having a bottom surface and a top lid to close the chamber;
- b) a tray to receive and hold one or more glass ampules, wherein the tray is placed inside the chamber on the bottom surface;
- c) the top lid comprising of one or more sealing heads to seal one or more glass ampules, each sealing head comprising of a top section and a bottom section, wherein the bottom section has a cavity configured to receive a top head of each glass ampule to be sealed, and a set of conductive wires passed through the lid from the top section to each cavity forming a set of electrodes in each cavity, whereby the electrodes can generate a set of plasma arcs across each cavity;
- d) a power source to generate the set of plasma arcs to heat, melt and seal the top head of each glass ampule.
