    摘要： A silane or siloxane containing at least one organic group is prepared by a hydrosilylation reaction between a silane or siloxane (A) containing at least one Si—H group and an allyl compound (B) in the presence of a noble metal catalyst. The silane or siloxane (A) and the allyl compound (B) are fed continuously through a reaction zone which is maintained at a temperature in the range 115–200° C. and which is provided with heat exchanger means to dissipate the heat from the exothermic hydrosilylation reaction. The residence time of (A) and (B) in the reaction zone is less than 20 minutes.

    摘要： A system and a method are disclosed for controlling structural deterioration of a vehicle parking structure by arresting deterioration caused by road salt erosion and corrosion of concrete floors and reinforcing steel in that structure. The invention includes spray washing the underside of vehicles prior to entry into the parking structure to remove road salt and thereby reduce road salt corrosive action within the facility. The invention further comprises arresting corrosion due to road salt which already has penetrated the concrete floors within the parking structure by the application of a chemical detergent which neutralizes the road salt that previously has penetrated the concrete.

    摘要： A machine for drying granular materials such as sand and gravel. The machine includes coaxial inner and outer cylinders. Moist sand is introduced into an inlet end of the inner cylinder and gravel is introduced into the inlet end of the outer cylinder. The sand is moved along the inner cylinder by impellers toward the outlet end of the inner cylinder in heat exchange relation with the inner cylinder while the sand is heated to evaporate water therefrom. The heated sand is directed from the outlet end of the inner cylinder into an inlet end portion of the outer cylinder to mix with the gravel. Impeller assemblies mounted on the interior of the outer cylinder raise the sand-gravel mixture as the cylinders rotate to cause the sand-gravel mixture to advance along the space between the cylinders toward the outlet end of the outer cylinder and to cascade against an outer wall of the inner cylinder. End portions of the inner cylinder are carried by support assemblies mounted on the outer cylinder. Resilient support assemblies support a central portion of the inner cylinder. The resilient support assemblies accommodate variations in diameter of central portions of the cylinders during operation of the machine.

    摘要： A machine for drying granular materials such as sand and gravel. The machine includes coaxial inner and outer cylinders. Moist sand is introduced into an inlet end of the inner cylinder and gravel is introduced into the inlet end of the outer cylinder. The sand is moved along the inner cylinder by impellers toward the outlet end of the inner cylinder in heat exchange relation with the inner cylinder while the sand is heated to evaporate water therefrom. The heated sand is directed from the outlet end of the inner cylinder into an inlet end portion of the outer cylinder to mix with the gravel. Impeller assemblies mounted on the interior of the outer cylinder raise the sand-gravel mixture as the cyliners rotate to cause the sand-gravel mixture to advance along a space between the cylinders toward the outlet end of the outer cylinder and to cascade against an outer wall of the inner cylinder. Catch plate assemblies mounted on the outer wall of the inner cylinder and extending outwardly therefrom catch the sand-gravel mixture as the sand-gravel mixture cascades against the outer wall of the inner cylinder to hold the sand-gravel mixture in heat exchange relation to the inner cylinder as the cylinders revolve so that an outlet end portion of the inner cylinder can heat the sand-gravel mixture to a sufficient temperature that moisture in the gravel is caused to evaporate, and the sand-gravel mixture is cooled by the moist sand in an inlet end portion of the inner cylinder as the sand-gravel mixture advances to the discharge end of the outer cylinder. The cylinders are driven by a chain which runs on a sectional sprocket mounted on the outer cylinder. Sections of the sectional sprocket are separately mounted on the outer cylinder so that the outer cylinder can flex with changes of temperature of portions thereof.
