An automated irrigation and chemical treatment system comprising a user input device adapted to communicate with a control unit; a mixing chamber adapted to communicate with the control unit and connected to a water supply and chemical canisters, wherein each canister has a sensor to monitor fluid level therein, and control valves for connecting the mixing chamber to a network of pipes. Sprinkler heads connected to the network of pipes each include, a control valve adapted to control fluid flow to a water delivery nozzle by an electro magnet controlled rubber coated ferric ball closure member. The sprinkler heads include water and chemical saturation sensors and the sprinkler heads also communicate with the control unit via wireless transceivers. Multiple zones covered by the system may be treated according to predetermined schedules.

Polybutylene terephthalate having good heat stability and excellent hydrolysis resistance is continuously produced in a series of a first reactor for reacting an aromatic dicarboxylic acid comprising terephthalic acid as a main ingredient or a derivative thereof with a glycol comprising 1,4-butanediol as a main ingredient, thereby producing an oligomer with an average degree of polymerization of 2.2 to 5, a second reactor for polycondensating the oligomer from the first reactor, thereby preparing a low polymerization product with an average degree of polymerization of 25 to 40, and a third reactor for further polycondensating the low polymerization product from the second reactor, thereby producing a high molecular weight polyester with an average degree of polymerization of 70 to 130, or followed by a fourth reactor for further polycondensing the polyester from the third reactor to an average degree of polymerization of 150 to 200, thereby producing a high molecular weight polyester. Another third reactor or a plurality of third reactors can be provided in parallel to the third reactor, thereby producing different kinds of polybutylene phthalate with different degrees of polymerization from that produced in the main line of the third and fourth reactors or adjusting operating conditions of each of a plurality of the third reactors to increase kinds, precise quality.

A method of improving gas, water, water vapor, and / or grease resistance of a porous material is disclosed which comprises treating the material with a first treatment agent followed by the application of wax and poly(vinyl alcohol) and optionally a polyamine. Porous materials that have a multi-layer coating that includes a first coating of a first treatment agent and a second coating of wax, poly(vinyl alcohol), and optionally a polyamine are also disclosed.

The present invention relates to coding of SNR enhancement layer data produced during video signal encoding. The present method determines order or blocks in a picture according to a probability table that is obtained from frequencies of locations where non-zero data exists, scans and codes data on each block to data stream as selecting blocks in the determined order, updates the probability table, re-determines order of blocks in the picture based on the updated probability table, and scans and codes data on each block to data stream just after location where the previous scanning is suspended as selecting blocks in the re-determined order. The present invention increases probability to provide a decoding side with more data that contributes to video quality improvement.

To provide a method of fabricating a polyurethane foam with micro pores, and a polishing pad therefrom, the method including steps of (a) adding a nonionic surfactant into at least one of a first ingredient including an isocyanate group-containing compound and a second ingredient including an active hydrogen group-containing compound, (b) agitating and mixing the mixture of the first ingredient and the second ingredient while adding a non-reactive gas thereto, (c) discharging the mixture out of a container at a predetermined rate, and (d) injecting the discharged mixture into a mold so as to form a mold body into a predetermined shape.
