Abstract: A conduit locknut wrench for use in the electrical trade and designed for tightening and loosening both six and eight tooth conduit locknuts. The conduit locknut wrench allows the electrician the ability to access hard to reach locknuts at any angle and around any obstruction including other locknuts with or without protruding wires. The small light weight wrench has very thin dimensions and includes a C-shaped head with two arcuate arms, two opposed engagement teeth, an elongated thin neck and a handle portion. The handle portion includes a screwdriver leverage hole and an oversized belt clip hole.

Abstract: An electric lighting device created for use as a safe, long lasting, authentic looking alternative to a flame bearing candle. This electric ‘candle’ being made from real candle wax, or hollowed out candles with the wicks removed. The ‘candle’ can be scented or colored, and the glow is authentic and pleasing being viewed through real candle wax. Miniature lamps suspended in a clear or yellowish heat resistant medium provide the source lighting. The glow of the artificial flame is color and volume-of-output matched to that of a real flame and realism is added by simulated flame movement with the use of an adjustable oscillator circuit hidden inside the candle. This flameless ‘candle’ can be used safely unattended, and is realistic in that real candle wax, or real used candles, are used for the body of the device.

Abstract: An electric lighting device created for use as a safe, long lasting, authentic looking alternative to a flame bearing candle. This electric ‘candle’ being made from real candle wax, or hollowed out candles with the wicks removed. The ‘candle’ can be scented or colored, and the glow is authentic and pleasing being viewed through real candle wax as opposed to an artificial medium. Instead of a dangerous flame, miniature lamps suspended in a clear or yellowish heat resistant medium provide the source lighting. The glow of the artificial flame is color and volume-of-output matched to that of a real flame and realism is added by simulated flame movement with the use of an adjustable oscillator circuit hidden inside the candle. This flameless ‘candle’ can be used unattended, hence the name Safety Candle, and is much more realistic than the prior art in that real candle wax, or real used candles, are used for the body of the device.

The conduit locknut wrench allows the electrician the ability to access hard to reach locknuts at any angle and around any obstruction, including other locknuts with or without protruding wires. The small light-weight wrench has very thin dimensions and include a C-shaped head with two arcuate arms, two diametrically opposed engagement teeth, an elongated thin neck, and a handle portion. The handle portion includes a screwdriver leverage hole and an oversized belt clip hole.

Abstract: Methods and apparatuses for detecting leakage of hydrocarbons from and preventing corrosion of underground storage tanks. Soil samples near an underground storage tank are taken and analyzed in the field, preferably using hexane as a solvent to detect the presence of hydrocarbons such as heating and waste oil. The soil-to-tank potential of the tank and the presence of water within the tank are measured and, if warranted, cathodic protection provided to the tank to prevent corrosion or further corrosion.
