    Abstract: An improved wheelbarrow is disclosed, comprising a wheel, a tray, a pair of handles, and a front guard, the improvement being in the handles and the front guard, in that each handle is provided with a roundish handlegrip including a first grip, round grip portion and second grip to facilitate an easier and safer forward dumping of load without switching handgrips, and in that the front guard facilitates a stabler forward dumping of load. The front guard may comprise at least one bar portion in parallel to the wheel axis or a curved plate. The front guard may alternatively comprise a pair of bar portions extending along the circumference of the wheel.

    Abstract: This invention relates to a process for producing .alpha., .beta.-unsaturated alcohol, which uses unsaturated aldehyde as a starting material, and in which only the aldehyde group in the unsaturated aldehyde is selectively hydrogenated by hydrogen transfer reaction, while the carbon-carbon double bond is left as it is. The method is characterized by using a catalyst which contains at least one oxide selected from the group consisting of oxides of yttrium, lanthanum, praseodymium, neodymium and samarium, as a main active ingredient. The catalysts exhibit high activity and selectivity, as well as a long life span.

    Abstract: A resin used for magnetic recording media, comprising a vinyl chloride copolymer containing vinyl monomers with hydroxyl groups and vinyl monomers with quaternary ammonium salt groups as component units. The resin is made by a method which comprises polymerizing an organic solvent solution containing vinyl chloride, vinyl monomers with hydroxyl groups and vinyl monomers with quaternary ammonium salt groups in a reacting apparatus to thereby precipitate a vinyl chloride copolymer, the interior surface of said reacting apparatus, which comes into contact with said organic solvent solution being coated with a fluororesin.
