Abstract: A system for conditioning electric power supplied from a three-phase alternating current electric power supply, including three phase lines, to a load, including the phase lines and an electric ground line, includes a plurality of first surge arresters, a plurality of second surge arresters, a plurality of third surge arresters, a three-phase surge suppressor, and a plurality of capacitors. The surge arresters minimize the amount by which the voltage between two phases and the ground line exceeds a rated value. The three-phase surge suppressor minimizes the amount by which the voltage between any of the three phases and the ground line exceeds a rated value. The capacitors minimize the amount by which the voltage between two phases falls below a rated value.

Abstract: A heating apparatus for heating rigid plastic pipe for the purpose of bending and forming the pipe. The heating apparatus includes an elongate housing that has a bottom wall, a pair of side walls, a first end wall, and a second end wall to define an interior. Each of the end walls has a pipe hole for permitting a user to insert rigid plastic pipe through the interior. An elongate burner member burns combustible gas to produce heat and is mounted to the housing and is positioned in the interior proximate to the bottom wall. A valve assembly regulates a flow of the gas to the burner member. An elongate burner plate disperses the heat generated by the burner member and is positioned above the burner member. A plurality of pipe support members support the pipe above the burner plate while positioned in the interior of the housing. An elongate cover member selectively covers the opening to the interior of the housing.

Abstract: Pharmaceutical delivery systems containing 7-dimethyl-6-deoxy-6-demethyltetracycline or a non-toxic acid addition salt thereof comprising mixtures or separate administration units of pH sensitive polymer coated spherical granules adapted to release the minocycline in a medium having a pH of in the range of from about 4.0 to about 7.5 and coated or uncoated quick release granules adapted to release minocycline in a medium having a pH of less than about 3.9 or minocycline powder, pH adapted multi-coated compositions and oral dosage unit form liquids, capsules or tablets containing the above are provided. These systems and formulations provide at least minimum therapeutic blood levels of minocycline for at least about 24 hours when administered to a subject only once-a-day. Methods for the preparation of the systems and formulations are provided as well.

Abstract: Pharmaceutical delivery systems containing 7-dimethyl-6-deoxy-6-demethyltetracycline or a non-toxic acid addition salt thereof comprising mixtures of a minor proportion of slow-release blended polymer coated spherical granules adapted to release part of the minocycline in a medium having a pH of below 3.9 and the rest in the range of from about 4.0 to about 7.5 and a major proportion of coated or uncoated quick-release granules adapted to release minocycline in a medium having a pH of less than about 3.9 and oral dosage unit form capsules containing the above are provided. These systems and formulations provide enhanced therapeutic blood levels of minocycline for at least about 24 hours when administered to a subject only once-a-day, regardless of whether the patient is fed or fasted. Methods for the preparation of the systems and formulations are provided as well.
