Abstract: A reclosing relay is provided with switch settings and microprocessor control to permit emulation of a variety of different styles of motor-driven reclosing relays in power distribution systems. The reclosing relay is particularly suitable for replacement of General Electric Co. ACR11A, ACR11B and other similar model reclosing relays that are not electrically compatible with one another. Plug-and-play compatibility is provided by a chassis with electrical contacts that are both physically compatible with a variety of relay cases, and by switches that reconfigure the functions of the external terminals for compatibility with these types. The relay has a built-in microcomputer controller that is programmable through a serial port, and that provides for software emulation of the various required electrical functions of the reclosing relay.

Abstract: A toothbrush which is adapted to contain a significant quantity of toothpaste therein and to dispense the toothpaste onto the toothbrush bristles. The toothbrush generally comprises a hollow handle having a brush head formed integrally on its top end, a disposable toothpaste containing cartridge supported within its interior, and a piston mechanism threadably attached to its bottom end. The piston mechanism is adapted to force the toothpaste out of the handle into a conduit formed through the brush head. The conduit leads from the interior of the handle to a plurality of outlet holes disposed below resilient valves in a rubber gasket layer which supports the bristles. The valves allow toothpaste to flow from the conduit onto the bristles of the toothpaste while preventing water or other fluids from flowing into the conduit to contaminate the toothpaste supply.

Abstract: An electronic engine controller limits the maximum temperature of a midbed point within a catalytic converter by determining an instantaneous temperature of the midbed point as a function of a temperature of exhaust gas at an exhaust flange, of a temperature variation of exhaust gas from the exhaust flange and exhaust gas inlet to the catalytic converter, of exhaust gas at an exhaust gas inlet to the catalytic converter, and as a function of a predetermined value indicative of a temperature rise of exhaust gas in the catalytic converter. The temperature is compared to a maximum midbed temperature range and a first air/fuel modulation variable is altered by a predetermined amount if the temperature of the midbed point is within the maximum midbed temperature range and the first air/fuel modulation variable is set to a predetermined value if the midbed temperature is below the maximum midbed temperature range.
