  • Fuel tank level indicator
    Patent number: 5279252
    Abstract: A fuel tank level indicator for indicating at a surface when a fuel tank is filled with fuel, such indicator installed on a fuel inlet pipe and having a loop pipe in line with the inlet pipe with a riser pipe at the top of the loop and a float member disposed in the riser pipe to raise an indicator member above the surface when the loop pipe fills with fuel. The fuel is prevented from backing up the inlet pipe by a back flow preventor and some of the fuel then passes into the riser pipe, raising the float member and its attached indicator member above the surface where it is visible by the person entering fuel into the inlet pipe who will then see the indicator member and stop the flow of fuel.

  • Method for making a silicon/copper contact mass suitable for direct reaction
    Patent number: 5250716
    Abstract: A method of preparing an active silicon/copper contact mass for the direct reaction of organic halides with silicon to make organohalosilanes by contacting a particle size distribution of silicon with a copper catalyst vapor, aerosol or a combination of vapor and aerosol. The copper catalyst aerosol can be produced by rapid nucleation of the vapor, by an exothermic reaction between copper metal and chlorine gas or by ultrasonic energy dispersion of a solution of a copper compound to a fine mist consisting of extremely fine particles 0.1 to 0.01 micron or smaller. The preferred copper catalyst is copper chloride. The small, sub-micron size copper chloride aerosol provides an efficient utilization of copper to form the active Cu-Si alloys on the silicon particles' surfaces.
