Transparent, oxygen-scavenging compositions containing polyesters comprising a cyclobutanediol and articles prepared therefrom

Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.

Method and apparatus for high speed electron beam rapid prototyping

An electron beam as a curing technique with dynamic beam control technology in order to produce arbitrarily shaped parts. The result of this is equipment which can create prototypes and parts rapidly without additional tooling. The electron beam from a low divergence gun is accelerated towards uncured monomer in vacuum. Deflection of the beam combined with a grid which is used to turn the beam on and off, creates a two dimensional curing path with a depth of approximately five (5) thousandths of inch. Successive layers of this type, built up as monomer is added, creates a three dimensional pattern. The layers can either be of uniform thickness, or can be varied in thickness by varying the energy of the beam.

Movable belt conveyor system

A movable belt conveyor system for a leach pad for use for sulfidic copper ore, where favorable conditions are to be generated for leaching out the copper by a slight compaction of the ore piled up into a dump for the microbiological leaching technology. The movable belt conveyor system of a length of up to several km is composed of a plurality of smaller belt segments, comprising a tail segment (70), standard segments (711-n) and a head segment (72), as well as a traveling tripper (8). To prevent the loading by these individual components from being excessively compacted by the weight of the device during multiple travel over the dump during the moving process, the belt drives with the driving drum are accommodated in the tail element (70), which is supported on the soil next to the leach pad. In addition, the traveling tripper (8) is designed as an independent unit with the belt drums, additional belt drives and the belt-tensioning means, which unit is autarchically displaceable on a caterpillar-type moving gear (85) of its own. Due to the moving of the belt on the caterpillar-type moving gears of the standard segments (711-n), on the head segment (72) and on the traveling tripper (8) as well as due to the absorption of the weight of the tail segment (70) by the transfer carriage (6), the surface pressure acting locally on the dump is reduced and the compaction of the ore on the dump due to being traveled over by the belt conveyor system remains low. Traveling over with a moving device, which frequently happens with the use of a moving caterpillar, is eliminated.

Use of ventilation air methane exhausted during mining of non-combustible ore in a surface appliance

Utilization of mine methane produced by mining a non-combustible ore, such as trona, as an energy source for heat, steam, and / or power generation. Such utilization is beneficial for a surface appliance which is close to surface outlet(s) of mine methane recovery system(s). A method for reducing greenhouse gas emissions generated during mining of a non-combustible ore uses the combustion of co-produced mine methane. The mine methane is recovered in a mine ventilation air exhaust with very low methane content and may be additionally recovered in a drainage gas, such as gob gas, with much higher methane content. The surface appliance may be selected from the group consisting of calciner, dryer, boiler, kiln, furnace, engine, turbine, power generation unit, co-generation unit, and any combinations thereof. Benefits may include reduction in energy purchases, reduction in greenhouse emissions, and / or gain through sale of carbon credits to the carbon market by registering carbon reductions.
