Macrocyclic polyester oligomers as carriers and/or flow modifier additives for thermoplastics

Concentrates of a carbon-based filler—such as carbon nanotubes, exfoliated graphite, and the like—and a macrocyclic polyester oligomer (also referred to herein as macrocyclic oligoester or MPO) are presented. When mixed with polymer, the MPO can act as a flow modifier, as well as a carrier for the carbon-based filler, allowing enhanced processability of the polymer-filler composite without adversely affecting the properties of the composite.

Method and apparatus for expendable tubing-conveyed perforating gun

Methods and apparatus are presented for a “disappearing” perforator gun assembly. In a preferred method of perforating a well casing, inserted into the well casing is a tubing conveyed perforator having an outer tubular made from a metallic glass alloy having high strength and low impact resistance. An inner structure is positioned within the outer tubular and holds one or more explosive charges. Upon detonating the explosive charges, the outer tubular is fragmented. The inner structure is preferably also substantially destroyed upon detonation of the one or more explosive charges. For example, the inner structure can be made from a combustible material, corrodible, dissolvable, etc., material. A disintegration-enhancing material is optionally positioned between the outer tubular and the inner structure. Additional embodiments are presented having gun housings which dematerialize upon detonation of the charges.

Low-energy-consumption low-carbon-emission economical energy-saving urban sewage treatment method

The invention discloses a low-energy-consumption low-carbon-emission economical energy-saving urban sewage treatment method. The method comprises the steps that: 1, the to-be-treated wastewater is collected by a sewage pipe network and then is filtered by lattices, and is lifted by a pump to enter a pulse water distribution pot of a novel efficient turn-back anaerobic biochemical pool (ABR); 2, the swage subjected to the treatment in step 1 flows into a circulation-flow biological oxidization pool; 3 the effluent water from the step 2 flows into an artificial reinforced biological contact oxidization pool reconstructed by a water body from natural tunnels and reservoirs; and 4, the effluent water from the step 2 or the step 3 flows into constructed wetlands. After the sewage is treated by the above steps, the most pollutants in the water are effectively removed and the treated effluent water reaches the standard first-grade A in GB 18918-2002 ''Discharge standard of pollutants for municipal sewage treatment plant''. The energy-saving sewage treatment purification process with low cost, low energy consumption, low carbon emission and low operating cost is particularly suitable for the sewage treatment in small towns or rural areas.

The present invention describes a specialized exercise apparatus and method for use that targets the muscles in and around the abdominal, oblique muscles and mid section of the body. The machine is comprised of a flat platform upon which an individual stands while grasping a pair of handlebars that are positioned at waist height. The handle bars are attached to the top of a vertical riser that extends downwardly and is attached to a pair of horizontal rotating pivot arms. The pivot arms are attached to the center of a rotating power pulley horizontally suspended by bearings below the forward area of said platform. The power pulley is connected by a belt to a resistance mechanism, such as a flywheel or turbine fan, again suspended by bearings, below the rear portion of said platform. In the flywheel adaptation of this invention, additional resistance is provided by an adjustable magnet that is controlled by a lever mounted to the side of the vertical riser. An individual stands upon the apparatus, and while keeping the lower body relatively stationary, rotates the handle bars, and thus the pivot arms, from side to side up to 220 degrees of rotation and provides an adjustable measure of resistance which produces an increased use of the muscles in and around an individual's torso and midsection area.
