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.

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.

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 invention discloses a phenolic lignin-based modified foaming phenolic resin, foamed plastic and a preparation method of the phenolic lignin-based modified foaming phenolic resin. The foaming phenolic resin comprises phenol, lignin, an acid catalyst, aldehydes, a base catalyst and an acid neutralizer.

The locking element has an outer edge that is generally opposite the pivot axis that opposes a base surface of the opening when the locking element is in the hold position. The outer edge is configured to pull away from the base surface when the locking element is rotated from the hold position toward the release position.

In a structure in which peripheral part of a diaphragm section of an electrical insulating film is covered with a protective film made of an organic material, the resistor wire on the diaphragm section crosses the peripheral part of the diaphragm section. At a place where a narrow wire of a resistance temperature detector and the like crosses the peripheral part of the diaphragm section, the protective film is thinner than the other part, and the dust impact resistance is reduced. At a place where a heating resistor wire connected to a heating resistor body or resistance temperature detector wires connected to resistance temperature detector bodies cross a periphery of the diaphragm section, a film component protruding from an electrical insulating film is arranged side by side with the heating resistor wire or the resistance temperature detector wires.
