Frozen smoothie kit and method

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.

Preparative purification process for human furin

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%.

Chlorinated hydrocarbon waste incinerator and valorization of chlorinated residuals process unit

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.

Deep dehydration pretreatment process for landfill sludge

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.

Cleaning product

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.

Rigid serrated surface for welding shoes

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.
