Abstract: Provided is an assembly structure of sun gear shaft and spline shaft of a gearbox for wind turbine. The assembly structure relates to the technical field of gearboxes for wind turbine and includes a sun gear shaft, a spline shaft, a mechanical pump drive gear, and a distance ring. The spline shaft is a hollow shaft. One end of the sun gear shaft is inserted into the spline shaft. The one end of the sun gear shaft inserted into the spline shaft is connected to the spline shaft through a spline pair. The mechanical pump drive gear is mounted at one end of the spline shaft. The inner diameter of the mechanical pump drive gear is less than the inner diameter of the spline shaft. The distance ring is disposed in the spline shaft. One end of the distance ring abuts against the inner side of the mechanical pump drive gear and is securely connected to the mechanical pump drive gear. Another end of the distance ring is spaced from the one end of the sun gear shaft in the spline shaft.

Abstract: Provided is a gear box including a lubricating oil pool arranged at a bottom of the gear box, and at least one oil stirring box that includes an oil storage chamber, the oil storage chamber being provided with an oil scooping port and at least one oil outlet. The at least one oil stirring box is arranged on a rotary component in the gear box and rotatable along with the rotary component. A lubricating oil in the lubricating oil pool is allowed to flow through the oil scooping port into the oil storage chamber when the at least one oil stirring box rotates to the lubricating oil pool. The lubricating oil in the oil storage chamber is further allowed to flow out of the at least one oil outlet to a lubrication point when the oil stirring box rotates to the vicinity of the lubrication point.

Abstract: A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the copolyester may also be extruded with the thermoplastic starch at a temperature low enough to avoid substantial removal of the moisture in the starch. Furthermore, the copolyester is also modified with an alcohol to contain one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a relatively low molecular weight.

The anti-adherent agents include botanical agents such as Soybean extract, Horse chestnut extract, Gypenoside, Resveratrol, Astragalus extract, Rhubarb root extract, Allium cepa extract, Cassia seed extract, Ginkgo biloba extract, and Silymarin, and combinations thereof. The efficacy of the botanical agents is microbe and surface dependent. Various delivery vehicles, including a wipe, may be used to deliver the composition to the surface.

Abstract: Methods for adjusting the solubility of a botanical oil in water, along with the resulting modified botanical oil and related products (e.g., treatment compositions, wipes, absorbent articles, etc.) are provided. In one embodiment, the method includes reacting the botanical oil to form a reactive product (e.g., having a hydroxyl group); and attaching a hydrophilic end group (e.g., a carboxylic acid, a carboxylic acid salt, a sugar, etc.) on the reactive product to form a modified botanical oil. The modified botanical oil generally, in most embodiments, has a greater solubility in water than the botanical oil (e.g., a solubility in water of about 10 grams per 100 grams of water or greater, such as completely soluble in water). The botanical oil includes, in one particular embodiment, an essential oil, such as those essential oil that include at least one terpene compound.

Abstract: Lateral-flow assay and time-resolved fluorescence technologies provide a sensitive tool for detecting norovirus particles in a sample. A flow-through assay device employs norovirus and norovirus G2 antibodies. The lateral-flow assay includes a conjugate pad having conjugated probes. The conjugated probes are particles modified with a binding member that is configured to bind with a norovirus. The particles also have a fluorescent label. A general method of detecting the virus includes (i) preparing a sample with contaminants, (ii) processing the sample and depositing it onto the assay device, and (iii) measuring the fluorescence signal.

Abstract: Formulations and wipes for imparting a sporicide to a surface are disclosed herein. To achieve the sporicidal efficacy of the product, a synergistic amount of an amine oxide surfactant and a mixture of oxidants is incorporated into the formulation. The operative sporicidal formulation contains a solvent, an amine oxide surfactant, a water soluble oxidant and a water insoluble oxidant. Typically, the formulation can contain about 0.05 to about 3.7 percent (by weight of the formulation) of an amine oxide surfactant, about 0.5 to about 4 percent (by weight of the formulation) of a water soluble oxidant, and about 0.1 to about 6 percent (by weight of the formulation) of a water insoluble oxidant.

Abstract: A method for forming a biodegradable aliphatic-aromatic copolyester suitable for use in fibers is provided. In one embodiment, for example, an aliphatic-aromatic copolyester is melt blended with an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
