Disclosed are methods for the heterogeneous catalytic transesterification of compounds having one or more ester groups and groups reactive under transesterification conditions, such as 1,1-disubstituted alkene compounds, with alcohols or esters and novel compositions prepared therefrom. Further disclosed are novel compounds and compositions prepared as a result of the methods.

Heterogeneous catalytic transesterification of ester compounds with groups reactive under transesterification conditions

Disclosed are compositions comprising polyester macromers containing in one or more chains the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes, and optionally one or more dihydrocarbyl dicarboxylates, and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols. The chains may contain the residue of the one or more diols and one or more diesters comprising one or more diesters 1,1-diester-1 alkenes and optionally one or more dihydrocarbyl dicarboxylates randomly disposed along the chains. Disclosed are methods of preparing the polyester macromers and incorporating them in a variety of polyester containing compositions such as coatings and films.

Polyester macromers containing 1,1-dicarbonyl-substituted 1 alkenes

A composition comprising about 97 mole percent or greater of one or more 1,1-dicarbonyl substituted-1-ethylenes and about 3 mole percent or less of one or more 1,1-dicarbonyl substituted-methanes. A process comprising: contacting in a fluid state one or more 1,1-dicarbonyl substituted-1,1 hydroxymethyl-methanes and greater than 200 ppm to about 1000 ppm of one or more strong acids based on the weight of the one or more 1,1-dicarbonyl substituted-1,1 hydroxymethyl-methanes with a zeolite catalyst at a temperature of about 180&#xb0; C. to about 220&#xb0; C. for a sufficient time to convert about 96 percent or greater of the one or more 1,1-dicarbonyl substituted-1,1 hydroxymethyl-methanes to one or more 1,1-dicarbonyl substituted-1-ethylenes.

High purity 1,1-dicarbonyl substituted-1-alkenes and methods for their preparation

A bucket is filled with water from a water tray that has been filled with water from a water tank. The water tray signals the water tank when it needs water. When a bucket reaches a certain position, the unit bar tips the water tray and the bucket receives the tray's water. The weight of the filled bucket causes it to drop to the water sewer below. The bucket dumps the water into the sewer. The water is pumped from the sewer to the water tank. The two units are attached by a sprocket cable at the unit bar, and the cable travels over three pulley wheels. The units are separated by a rack. The units have a generator mounted on a unit bar. The movement of the bar and the motor along rack generates energy.

The present invention relates to an improved method and instruction device for teaching a language based on kanji characters by presenting a compilation of approximately 210 to 420 key kanji in a systematic order. The student is then provided with the phonetic reading of the key kanji in Roman characters, hiragana and katakana. The method involves multiple reinforcement of the phonetic readings and recognition of the key kanji by providing homophones, radicals, Japanese names of the key kanji and the meanings of the key kanji. The final step includes presenting a Japanese writing for the student accompanied by the English translation, the phonetic reading and information on looking up words that the student does not know.

A compact, easily stowed removable drain line for a Recreational Vehicle holding tank provides a rigid straight line flow path to prevent puddling or trapping of waste flows between Recreational Vehicle holding tank and sewage dump station. The invention also provides for minimal force transfer into the holding tank structure and the drain valve, minimizing the possibility of accidental damage or rupture of these sensitive components. In particular, no exposed components exist during movement of the Recreational Vehicle, minimizing the risk of breaching of sewage during over road movement, and the invention particularly protects against damage from accidental movement of the vehicle while attached to the sewage dump station.
