    摘要： A method for the formation of monoalkyleneglycols, monoalkanolamines and alkylenediamines, comprising the steps of: (a) reacting ammonia or ammonium carbonate with an alkylenecarbonate to form a carbamate, (b) heating the carbamate to form a monoalkyleneglycol, an alkyleneurea and a 2-oxazolidinone, (c) further reacting the alkyleneurea and the 2-oxazolidinone with ammonium hydroxide to form ammonia or ammonium carbonate, a monoalkanolamine, and an alkylenediamine, (d) separating the ammonia or ammonium carbonate, the monoalkyleneglycol, the alkylenediamine, and the monoalkanolamine, and (e) recycling the ammonia or ammonium carbonate to reaction step (a).

    摘要： A golf putter head with base member and wing member is disclosed. The base member has a front face for contacting a golf ball in the performance of putting a golf ball. The front face extends in a direction along the axis of elongation of the base member. The wing member is relatively wide where at its connection interface with the base member, to assure that force is applied from the wing member evenly to the base member as a golfer swings the putter. The disclosure also covers a golf putter with the disclosed putter head and shaft assembly.
