When applied to the eye and orbit, this device can be used in hypothermia or hyperthermia applications, the control of intraocular pressure (IOP), and the application of treatment modalities. Methods of using the device in treating patients suffering from central retinal artery occlusion, anterior optic nerve disease, pathology of the choroid and retina including the macula, inflammation of the eye including the vitreous and anterior segment, glaucoma, inflammation and / or infections of the anterior and / or posterior segment of the eye, treatment before / during / after surgery of the eye, and the application of treatment modalities through a semi-permeable membrane are described.

The invention belongs to the field of pesticide production and particularly relates to a glufosinate separation and purification method. According to the method, the separation and purification is started when a glufosinate hydrochloride reaction solution in the steps of distilling the glufosinate hydrochloride reaction solution under reduced pressure to remove dilute hydrochloric acid, adding ammonia water to adjust the pH to maximally produce ammonium chloride, distilling under reduced pressure to remove water, adding a flotation solvent for dispersion, placing the material into a chute at specific temperature and speed, performing flotation separation according to the difference in the proportion of a principal component and subsidiary salt, removing the solvent, dissolving the material in aqueous methanol to remove trace ammonium chloride, filling ammonia gas to adjust the pH value to 8, performing centrifugation and drying to obtain a final product. The glufosinate separation and purification method uses a flotation method for separating the principal component glufosinate and an intermediate of the principal component from the subsidiary salt ammonium chloride and the aqueous methanol for purification and is high in yield, good in purity, simple in process, low in cost and is suitable for industrial production.

The invention relates to a kind of shell joint structure and its joint method. The joint structure consists at least two parts: upper shell, which bears a joint including(from its outside to its inside orderly) first concave, first convex, first flute and second convex; and lower shell, which also bears a joint including(from its outside to its inside orderly) first concave, first convex and second concave. In addition, the first concave and the first convex of the upper shell are relative to the first convex of the lower shell, and the first flute and the first convex of the upper shell are relative to the first convex and the second concave of the lower shell respectively, thus jointing the upper shell and the lower one together. Through the use of this type of shell joint structure and its joint method, shell shadow and line flows can be reduced and the increase of the electricity climbing distance of the electric clearance after the combination of the shells will enhance the appearance of the shells of electric devices and their components as well as their electric characteristic.

Apparatus and method for a continuous replenishing of the lift gas and maintaining the proper pressure and lift of a tethered medium altitude aerostat utilizing a novel feed tube running the entire length of the tether. A first end of the feed tube is connected to the aerostat while a second end is connected through a novel slip ring means to a pressure controlled helium ballast chamber and scrubber on the ground to maintain pressure and lift by a reversible compressing pump. A plurality of pressure and temperature sensors and tension gauges strategically placed inside and around the airship continuously monitor the temperature and pressure changes in the aerostat. A data retrieval and communication unit mounted on the aerostat collects measurement data from the pressure, temperature and tension sensors which is relayed to the ground station and the data is used to regulate lifting gas pressure inside the aerostat.

The invention discloses an environment-friendly thixotropic anti-rust oil. The anti-rust oil comprises the following raw materials by weight: 81 to 90 parts of bobbin oil, 0.1 to 0.3 part of hydroxyethylpyrrolidone, 1 to 2 parts of 1-hydroxyethyl-2-oleic imidazoline, 5 to 7 parts of dinonyl-naphthalene sulfonic acid calcium salt, 1 to 2 parts of organic bentonite, 0.7 to 1 part of polyoxyethylene nonyl phenyl ether, 3 to 4 parts of epoxidized soybean oil, 0.6 to 2 parts of decyl primary amine, 0.6 to 2 parts of Span-80 and 5 to 6 parts of an anti-rust auxiliary agent. The anti-rust oil provided by the invention has excellent performance and cleaning performance, certain lubricity and good thixotropy, so the anti-rust oil can form a stable oil film on the surface of metal, hardly flows and can maintain the stable oil film when a steel plate is rolled up, thereby reducing the application amount of the oil.

The invention discloses an efficient reformer for autothermal reforming of methane. The efficient reformer for autothermal reforming of methane comprises an external cylinder body and an internal cylinder body; the external cylinder body and the internal cylinder body are concentrically arranged cylinders; an annular space between the external cylinder body and the internal cylinder body comprisesa combustion chamber and a combustion buffering chamber, wherein the combustion chamber is formed in the upper part and used for supplying heat to combustion, and the combustion buffering chamber isformed in the lower part; and the cylindrical space in the internal cylinder body comprises a reforming buffering chamber and a reforming chamber, wherein the reforming buffering chamber is formed inthe upper part, and the reforming chamber is formed in the lower part of the reforming buffering chamber and used for hydrogen production by reforming. As an external combustion chamber of a reactor has a small section, and a reforming chamber of the reactor has a big section, the heat transfer resistance from the combustion chamber to the reforming chamber is reduced, the staying time of reforming gas in the reforming chamber is also increased, and the strong heat of combustion is sufficiently absorbed; moreover, compared with a common internal combustion and external reforming form, the efficient reformer for autothermal reforming of methane, disclosed by the invention, has the advantages that the heat exchanging areas of the combustion chamber and the reforming chamber are also increased, and the heat exchanging efficiency is made higher.
