Title: Hybrid circuit using miller effect for protection of electrical contacts from arcing
Inventor: LEE TONY J
IPC: H01H9/54
Filed: 1996-09-09
Abstract: An IGBT semiconductor device is connected across switching contacts which are to be protected from arcing. When the contacts are in a normally open configuration, the gate portion of the IGBT is connected to the emitter portion through the contacts, while when the contacts are in a closed configuration, the collector portion of the IGBT is connected to the emitter portion through the contacts.  A capacitor is connected in parallel with the gate-collector junction.  The combination of the stray collector gate capacitance and the additional capacitor is sufficient to maintain the IGBT device in conduction as the contacts are moving from their closed configuration to their open configuration, thereby preventing arcing across the contacts.

Abstract: A packaging for a grouping of casing sticks of artificial tripe or wrappers in an overlapping alignment having a quincuncial arrangement forming a parallelepiped block has a transparent cover which is adapted to surround the parallelepiped block. The packaging has a tubular configuration where two ends of the packaging overlap on the block. The overlapping two ends define a sealing line which is located upon the middle line of one of the larger surfaces of the block. The ends of the tubular element are folded so as to fit over the ends of the sheaths. Flaps at the open sides of the packaging are folded down onto the same surface of the block on which the sealing line is located, and specifically upon the end areas of the sealing line. The transparent packaging cover is stabilized by an adhesive tape strip which is placed covering the sealing line and the folded flaps. The adhesive tape may have an adhesive free section arranged to form a manual grab tab for allowing the package to be easily opened. The tape may extend at one end by a substantial length which reaches the opposite surface of the block upon which an intermediate length is defined which stands apart from the block and may be used as a manual block grip handle.

Title: Scanning laser demolding of ophthalmic lenses
Inventor: ROSS DENWOOD F
IPC: B29D11/00
Filed: 1997-09-08
Abstract: An apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation is applied to at least one of the mold portions in a predetermined scanning pattern through the intermediary of galvanometer-driven mirrors. Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force breaks the polymerized lens/polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions separate. The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.
