Mining method for co-extraction of non-combustible ore and mine methane A method for co-extracting non-combustible ore (e.g., trona) and methane from an underground formation comprising at least one methane-bearing layer and a non-combustible ore bed having a rock roof, comprising:

• • providing a well having a downhole end positioned above the ore bed roof;
  • mining an ore region from an initial cavity and removing the mined ore, thereby creating a subsequent cavity;
  • advancing the mining step to another ore region from the subsequent cavity;
  • allowing the roof of the initial cavity to cave so as to create a gob;
  • repeating the mining, advancing and caving steps, the caving being effective in generating fluid communication between the gob and the well downhole end and in fracturing the methane-bearing layer so as to release methane into the gob; and
  • recovering a gob gas comprising released methane through the well to the surface.

A frozen pellet for blending with other ingredients to make a smoothie is formed of a sugar sweetened yogurt or yogurt formulation diluted with water and frozen solid at temperatures between 0° F. and 32° F. The frozen-solid yogurt pieces eliminate the need for the use of ice in the smoothie making process. Instead the frozen-solid yogurt pieces simply are blended together with fruits, preferably also frozen, and a liquid such as a juice, soda or milk to make a cold smoothie having a desirable thick consistency.

Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50-fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on Capto-MMC(TM) resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20% pure preparation obtained after Capto-MMC(TM) chromatography had already a purification degree allowing on-column maturation of pro-VWF. Then an additional Arginine Sepharose chromatography purification was carried out. This two column process for purification of truncated human furin resulted in an almost pure furin preparation with a specific activity of approximately 290,000 U furin/mg protein and a yield of about 50%.

A closed-loop process for incinerating chlorinated hydrocarbon-containing material without the emission of air borne pollutants. The chlorinated hydrocarbon-containing material is incinerated, preferably in the substantial absence of air, thereby producing a gaseous effluent containing hydrogen chloride and pollutants such as carbon dioxide, acid gases, and halogenated compounds. The gaseous effluent is passed through a hydrogen chloride purification system to remove hydrogen chloride from the gaseous effluent and to produce a concentrated anhydrous hydrogen chloride gaseous stream. The gaseous effluent is passed through at least one sorbent bed, such as a bed of activated carbon, to remove halogenated pollutants from the effluent. The pollutants are desorbed from the one or more sorbent beds and recycled to the incinerator where they are decomposed by combustion.

The invention discloses a treatment process for stable dehydration of ammonia-alkali process alkali residues. By taking the concentration of alkali residues as a standard, the concentration of the alkali residues is controlled to be within a process interval, and then the alkali residues are modified by adding a chemical conditioner, so that the alkali residues meet related environmental protection indexes and reach the class I general industrial solid waste standard; and the diluted alkali residues are mechanically dehydrated to obtain alkali residues subjected to stable dehydration treatment, and meanwhile, the alkali residue clear liquid is recycled for diluting the alkali residue slurry. The concentration of the alkali residue slurry is used as the standard of the dilution degree of the alkali residue slurry, so that the generation of the alkaline residue slurry in the dilution process is effectively reduced, the effect of conditioning the alkali residues by a chemical conditioner is exerted to the maximum extent, the waste of the chemical conditioner and water is avoided, and the treatment cost of dehydrating the alkali residues by an ammonia-alkali process is saved.

The invention relates to a deep dehydration pretreatment process for landfill sludge. The deep dehydration pretreatment process comprises the following steps of (1) performing viscosity measurement onexcess sludge of a sewage treatment plant to obtain a sludge viscosity standard range; (2) diluting to-be-treated landfill sludge based on the sludge viscosity standard range obtained in step (1), then measuring the viscosity of the to-be-treated landfill sludge so that the viscosity of the diluted landfill sludge is within the sludge viscosity standard range and is smaller than a maximum value of the sludge viscosity standard range; and (3) adding a chemical conditioning agent to the diluted landfill sludge, conditioning and then dehydrating the diluted landfill sludge to obtain the deep dehydration pretreatment sludge having a water content of less than 60%, and recycling the sludge dehydration liquid for diluting the landfill sludge. Compared with the prior art, the deep dehydration pretreatment process for the landfill sludge effectively reduces the generation of the dehydration liquid and maximizes the effect of the medicament by using the sludge viscosity as a reference for thelandfill sludge dilution degree, and fills in the gap of the technical field of pretreatment before conditioning of the landfill sludge.

Opposing, paired and positionally adjustable air cooled welding shoes, run-off tabs, and sumps affixed at the junction of workpieces to be welded with an Electroslag welding system. The air-cooled shoes are capable of being controlled between 800 to 1000 degrees Fahrenheit, resulting in faster welds, smaller heat affected zone in the workpieces welded, and far less base metal dilution. These significant results provide a smaller weld grain structure and much stronger bond in the weld fusion zone.

There is described a method for maintaining the concentration of a treatment liquid bath in the production process for contact lenses which comprises the process steps of rinsing each lens in a water bath immediately prior to immersing the lens in a liquid bath for extraction and/or rinsing and/or coating thereof. Immediately following the rinsing in the water bath each contact lens is immersed in an arrangement of two or more successive treatment liquid baths of the same kind. The treatment liquids in the successive baths are continuously renewed and are transported from one bath to the preceding bath in a direction opposite to a transport direction of the contact lenses from bath to bath. A metered volume of treatment liquid is continuously introduced into the last bath of the arrangement of treatment liquid baths in dependency of a measured concentration, and a specified volume of treatment liquid is continuously removed from the first bath.

The invention is a detergent solution for cleaning a receptacle for milk or liquid milk-derived products, the detergent solution comprising water, one or more types of surfactant and an odour absorbing compound. The surfactants are provided to dissolve greasy milk-based residues from the receptacle and the odour absorbing compound is provided to neutralise odours produced by any remaining milk-based residues not removed by the surfactants. The detergent solution is water-based so that it can be rinsed off easily in a sink in the home. The detergent solution is particularly suited to plastic receptacles because plastic is more prone to accumulating mal-odour producing bacteria. This is because a plastic surface is more porous than glass so it is more difficult to remove greasy residues from a plastic surface and therefore grease can build up in the pores, out of the reach of surfactants, and provide a place for odour-producing bacteria to grow. An odour absorbing compound does not remove the residue but can neutralise the odours from the residue. The invention also discloses a method for dispensing a detergent solution comprising at least one surfactant, the method comprising ejecting detergent solution from a reservoir in the form of a spray, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution. The invention discloses also a method of cleaning a receptacle for milk, or liquid milk-derived products, the method comprising: spraying a detergent solution comprising at least one surfactant onto the receptacle, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution.

Adjustable articulated air-cooled copper welding shoes, capable of being controlled between 800 to 1000 degrees Fahrenheit during Electroslag welding operations, result in faster welds, smaller heat affected zone in the workpieces welded, and less base metal dilution. The shoes thus provide a smaller weld grain structure and stronger bonds in the weld fusion zone.

Opposing, paired and positionally adjustable serrated water-cooled copper welding shoes, run-off tabs, and sumps affixed at the junction of workpieces to be welded with an Electroslag or Electrogas welding system. The serrated water-cooled copper welding shoes are capable of being controlled between 150 to 200 degrees Fahrenheit, and the welding flux plating over the serrations reduces over-chill to the molten weld puddle while also reducing the amount of heat that the serrated water-cooled shoe removes from the surface of the work piece. This reduction in base material heat allows the welding operator to reduce the weld voltage to dramatically decrease the size of the weld nugget and, in turn, to decrease the heat input from the welding process into the work piece. These significant thermo-dynamic improvements to the Electroslag or Electrogas welding process provide a smaller weld grain structure and much stronger bond in the weld fusion zone.
