  • Adjustable pre-load screw and nut assembly
    Patent number: 5252015
    Abstract: An adjustable pre-load screw and nut assembly is described including a screw with external helical threads and a nut having two separate portions each with internal threads complementary to those on the screw. An adjustment nut and adjacent O-ring can be turned an amount sufficient to interengage the nut portions to urge them apart and thus establish contact with opposing surfaces of the screw threads to effect pre-loaded contact therewith to eliminate backlash when the screw is turned in either direction.

  • Electrothermal reactor
    Patent number: 3956885
    Abstract: An electrothermal reactor is provided to control the decomposition of chemical compounds and mixes and generate a gas flow. The reactor embodies a reaction chamber which has an electrical heat source. Means are provided to inject the chemical compounds and mixes into the chamber such that the compounds will vaporize. The heat source raises the temperature within the chamber to the reaction temperature wherein the chemical compounds and mixes react, thereby releasing chemical energy and producing a gas flow of the reaction products.
