Abstract: Examples disclose a computing system comprising a host device with a connection socket to support multiple types of cables by detecting a first key position and a second key position for determination of the type of cable. Further, the computing system comprises a switching circuit to determine a logic state of each of the key positions. Additionally, the switching circuit is to deliver power associated with the type of cable based on the logic states of the key positions.

Abstract: An air turbine apparatus for use with a combustion engine either as a muffler or as an air intake device is comprised of a housing defining an expansion chamber and an airfoil positioned within the housing. The airfoil includes a central aperture extending longitudinally therethrough that is in fluid communication with both the inlet and the outlet of the housing. The airfoil is configured to allow gases flowing through the inlet to flow between the outer edge of the airfoil and the housing and through the aperture of the airfoil. In addition, the air traveling through the housing is caused to spin as it travels through the housing. This rotational flow increased the rate of flow of gases through the air turbine device. A chop core is provided between the airfoil and the outlet of the housing to encourage turbulent flow of gases without restricting flow to produce a muffling effect and thus a dampening of noise from the combustion engine.
Abstract: Disclosed is a self-contained, portable apparatus for cleaning chemical and/or radioactively contaminated articles. A cleaning chamber is provided where contaminated articles are placed. Solvent from a solvent reservoir is sprayed onto the contaminated articles to dissolve the chemical contaminants and to dislodge the radioactive particulates. The solvent and contaminants drain through a short vertical duct connecting the cleaning chamber to the solvent reservoir. There is a cooling means present in the short vertical duct which serves to condense the solvent vaporized during the cleaning operation. A filter means is provided to filter particulate contaminants from the solvent before the solvent is delivered from the solvent reservoir to the cleaning chamber.
Abstract: Disclosed is a method of and apparatus for removing chemical nerve agents such as tabun, sarin and soman and chemical blister agents such as mustard gas and lewisite from a cleaning solvent such that the solvent is rendered contaminant free and safely resuable in future cleaning operations. The solvent, trichlorotrifluoroethene and the contaminants are soluble in one another and are all of non-polar configuration. Removal is effected by preferential adsorption of the contaminants from the solvent. Effective adsorbents are Fuller's Earth, activated charcoal, activated alumina and silica gel.
Abstract: Garments contaminated with radioactive, toxin, biological and/or chemical contaminants are deposited in a cleaning drum and the drum is agitated during a wash cycle. A dry cleaning solvent is added to the drum during the initial wash cycle and then drained to a distillation means. Within the distillation means, there is a neutralizing agent which deactivates the biological and toxin contaminants and chemically breaks down the chemical contaminants removed with the dry cleaning solvent from the cleaning drum. Dry cleaning solvent is then continuously added to the drum during the secondary wash cycle and continuously removed from the drum. After the dry cleaning solvent is removed from the drum, and before it is pumped back to the drum, the dry cleaning solvent is filtered to remove remaining trace particulate contaminants. The dry cleaning solvent is also passed through an adsorber where remaining trace chemical contaminants dissolves in the dry cleaning solvent are removed.
