Title: Anti-shock mechanism for an electronic lock
Inventor: RICE LARRY
IPC: E05B65/20
Filed: 1999-11-12
Abstract: The present anti-shock mechanism for an electronic lock (10) is designed to limit displacement of the solenoid plunger when an external force acts on the lock case (20) of an electronic lock. An external force applied in a horizontal direction parallel to the direction of plunger motion may cause the solenoid plunger to displace allowing the lock to be opened without authorization. The addition of a properly sized anti-shock mechanism (60) limits displacement of the solenoid plunger due to an external force or impact and allows movement of the solenoid plunger when the solenoid plunger movement is due to an authorized access. When the lock is subjected to a force or impact, the anti-shock bellcrank (60) moves or rotates to a position that will limit the plunger's movement and prevent the mechanical components of the lock from being placed in positions that would permit the lock to be opened.

Title: High linearity, low offset interface for hall effect devices
Inventor: HEINZ-BUETHE KARL
IPC: G01R21/08
Filed: 1999-10-07
Abstract: A Hall effect sensor (10) or device may be used in a variety of embodiments,  such as measuring current within an associated conductor by helping to measu re flux density within a gap of a ferromagnetic power meter core, such as in a power meter. A high linearity interface for a Hall effect device is provided  for minimizing offset effects without using complicated electronic circuits.  First (48) and second (50) levels of modulation relative to line frequency (42) are used to synchronize Hall effect device input switching circuits and  feedback loops for improved elimination of offset signals or noise from the ultimate system output. The substrate (12) of the Hall effect device may be connected electrically to an output pin of the Hall device or to a separate virtual ground to eliminate any effects caused by asymmetry of the voltage appearing in the channel relative to the substrate. The net effect of the hi gh linearity interface is to eliminate any adverse effects to linearity of the system, especially at low magnetic flux levels where the output voltage of t he Hall device would be relatively small compared to the offset voltage levels involved. The interface virtually eliminates adverse effects from operationa l amplifier input offset voltages, Hall effect device output offset voltages, and any common mode voltages.

Title: Iron production method of operation in a rotary hearth furnace and improved furnace apparatus
Inventor: KIKUCHI SHOICHI
IPC: C21B13/10
Filed: 1999-11-12
Abstract: The present invention is an apparatus and method for the direct reduction of iron oxide utilizing a rotary hearth furnace to form a high purity carbon-containing iron metal button. The hearth layer may be a refractory or a vitreous hearth layer of iron oxide, carbon, and silica compounds. Additionally, coating materials may be introduced onto the refractory or vitreous hearth layer before iron oxide ore and carbon materials are added, with the coating materials preventing attack of the molten iron on the hearth layer. The coating materials may include compounds of carbon iron oxide silicon oxide, magnesium oxide, and/or aluminum oxide. The coating materials may be placed as a solid or slurry on the hearth layer and heated, which provides a protective layer onto which the iron oxide ores and carbon materials are placed. The iron oxide is reduced and forms molten globules of high purity iron and residual carbon, which remain separate from the hearth layer. An improved apparatus includes a cooling plate that is placed in close proximity with the refractory or vitreous hearth layer, cooling the molten globules to form iron metal buttons that are removed from the hearth layer. The improvements due to the present apparatus and method of operation provide high purity iron and carbon solid buttons, which are separate from slag particulates, and discharged without significant loss of iron product to the interior surfaces of the furnace.
