    摘要: The present disclosure describes operationally simple methods for the low temperature, catalytic activation of carboxylic acids for organic reactions, in particular for direct amidation reactions with amines. The methods involve the use of orthosubstituted arylboromc acids of the formula (I), wherein the groups R1 to R5 are as defined herein. In preferred embodiments R1 is halogen. The arylboromc acids catalyze nucleophilic 1,2-addition reactions, conjugate 1,4-addition reactions, and cycloaddition reactions, including Diels-Alder reactions involving α,β-unsaturated carboxylic acids.

    摘要: An apparatus for rotary dumping of rail cars, including a material receiving pit. A rotary rail car dumper includes a rotational frame supporting at least one baffle. The rotational frame is configured to dump a load from a rail car during rotational motion of the rotational frame between an upright position wherein the entire load is in the rail car and a dumping position wherein the load can exit the rail car. A backside airflow diverter is located beneath the rotational frame and includes a curved upper surface. A lower margin of the at least one baffle contacts the curved upper surface during at least part of the rotational motion of the rotational frame. A backside hood is located beneath the backside airflow diverter on the back side of the pit.

    摘要: An apparatus for rotary dumping of rail cars, including a material receiving pit. A rotational frame is disposed at least partially in the pit, is configured to dump a load from a rail car during rotational motion. A backside airflow diverter is disposed within the pit along with a backside hood for removing contaminated air. At least one baffle contacts the upper surface of the backside airflow diverter during at least a portion of the rotational motion. The invention includes an end of hood close off panel extending substantially from a platen supporting wall to the backside air flow diverter or an end ring baffle that extends from a grizzly upwardly to approximately the perimeter of a supporting ring and from the backside airflow diverter toward a dump side of the pit whereby dust laden air is substantially prevented from escaping from the pit under the end ring baffle.

    摘要: A method and apparatus for controlling dust generated by the rotary dumping or rail cars may include one or more flexible baffles are provided to the back-side of a rotary dump frame to seal a portion of the material receiving pit during a portion of the rotary motion. The dust cloud generated by this dumping is retained in the pit for an increased time due to tumbling of the cloud induced by the baffles and other features of the facility. A plurality of intake ducts removes the dust cloud from the pit for transfer to a remote filtering facility.

    摘要: A nickel-based alloy composition is disclosed comprising from about 0.05 to about 3 percent by weight beryllium; from about 1 to about 40 percent by weight copper; no greater than about 10 percent by weight chromium, the balance being nickel. The alloy composition may be adjusted to achieve a high, as-cast hardness alloy over a wide range of alloy component contents, or a moderate, as-cast hardness alloy useful for forming articles such as golf clubs which has relatively constant mechanical properties over a wide range of copper contents.
