摘要： A small motor vehicle such as a motorcycle having a front fairing with the radiator, engine and the like positioned therein. A front fender is provided which includes a peripheral portion positioned about a portion of the front wheel and extending fore-and-aft between the struts of a front fork. The fender further includes side plates including narrow upper portions extending to just outwardly of the front fork and lower portions. The lower portions extend outwardly and rearwardly to lie in a streamline aligned with the lower sides of the vehicle fairing. Further edge portions extend downwardly from the peripheral portion of the fender rearwardly of the front fork so as to create an appropriate fender well.

摘要： A process for producing a granular slow-acting nitrogenous fertilizer, which comprises blending an aqueous methylol urea solution to a urea-isobutyraldehyde condensate powder or a mixture thereof with a urea-formaldehyde condensate powder, and granulating the resulting blend while subjecting the methylol urea to dehydration condensation under an acidic condition to form a urea-formaldehyde condensate.

摘要： A process for producing a methylol urea solution which comprises carrying out addition reaction between urea and formaldehyde in the presence of water and an alkali, wherein said alkali is a polyphosphoric acid salt; and a process for producing a slow-releasing nitrogenous fertilizer which comprises subjecting the resulting methylol urea solution to dehydration condensation and drying the resulting condensate are disclosed. The methylol urea solution undergoes no substantial pH variation with time either during or after the addition reaction, and the fertilizer obtained therefrom is excellent in slow-releasing properties.
摘要翻译：一种制备羟甲基脲溶液的方法，其包括在水和碱的存在下进行尿素和甲醛之间的加成反应，其中所述碱是多磷酸盐; 以及一种生产缓释氮肥的方法，其包括使得到的羟甲基脲溶液进行脱水缩合并干燥所得的冷凝物。羟甲基脲溶液在加成反应期间或之后不会随时间发生显着的pH变化，并且由此获得的肥料具有优异的缓释性能。
