  • Well scrubber
    Patent number: 7121336
    Abstract: A cylindrical brush for scrubbing the inside surface of a pipe is made of bristles attached to a springy helix. The diameter of the brush is greater than the inside diameter of the pipe. When the brush is pushed through the pipe the helix collapses and compacts the bristles to scrub the surface. When the brush is released in the pipe, the helix expands and spreads the bristles; thereby aiding in release of debris collected on the bristles during the scrubbing.

  • Method for producing carbamates and method for producing isocyanates
    Patent number: 7122697
    Abstract: A method for producing carbamates that enables carbamates to be produced at low costs, with high selectivity and high yield, and in a simple manner, and a method for producing isocyanates that enables isocyanates industrially used to be produced by using the carbamates obtained by the carbamates producing method. Nonaromatic amine selected from the group consisting of aliphatic amine, alicyclic amine, and aralkyl amine is allowed to react with alkylaryl carbonate to thereby produce carbamates. Also, the carbamates thus obtained are thermally decomposed to thereby produce isocyanates. When carbamates are produced in this method, alkyl carbamates can be obtained with high selectivity and at high yield by using simple equipment. Also, when isocyanates are produced in this method, polyisocyanates used industrially as the raw material of polyurethane can be produced in a simple manner and with efficiency.
