Abstract: A water closet seat assembly with a closet seat for use in an elevated or a conventional position. The seat assembly includes support walls mounted on opposite sides of the water closet and provided with two vertical and opposed guideways. The closet seat has a central opening for access to the receptacle and guides which project into the guideways and are free to slide and pivot therein. Support protrusions project inwardly from the support walls to support the closet seat in the elevated position. As the closet seat guides are moved to the bottom of the guideways, an extended lip portion of the closet seat which rests on the support protrusion, moves rearwardly to clear the protrusions and permit the closet seat to be lowered to its conventional position adjacent the upper edge of the water closet receptacle. Arm rests may extend from the walls to provide support for the arms of the user.

Abstract: A two piece top rail assembly for interchangeable use in constructing both open top trailers with exterior posts and exterior skin. The rail assembly includes an elongated outside element having in cross section a depending base leg for securing to the posts on the trailer. A lower cross leg is secured in angle to the base leg and an intermediate leg is secured to the lower cross leg and has at least a portion extending substantially in the opposite direction to the base leg. An upper cross leg is secured to the intermediate leg and extends at an angle substantially in the direction toward the base leg. An inside element that may be used in two positions in contact with the outside element includes a connecting leg extending between and connecting first and second transverse leg. Openings which are in alignment are provided in the first and second transverse leg for receiving the roof bow.

Abstract: A process and composition for removing sulfur dioxide from combustion gases particularly those emitted from the burning of high sulfur coal. The gases are treated with a liquid composition comprising 1 to 10 pounds of ClO.sub.2 per hundred pounds of SO.sub.2 to be treated and from 5 to 40 pounds of detergent per pound of ClO.sub.2. The composition is preferably alkaline, and may be injected as an atomized spray into the stack carrying gases, to preferably produce a stack gas of a pH between 7.0 and 7.5. The composition may also include 0.1 to 40 pounds of alkali per pound of ClO.sub.2 and 0.1 to 20 pounds of ammonia per pound of ClO.sub.2. Additionally, 1 to 30 pounds of an organic solvent per pound of ClO.sub.2 may be added.

Abstract: A portable olefin gas generating apparatus such as for generating ethylene to initiate the ripening of various climateric fruits. A reaction liquid is fed by gravity to a reaction chamber where it is catalytically converted into the desired olefin gas.The reaction liquid includes an alcohol such as ethanol, a denaturing agent such as a ketone, an ester of a monocarboxylic acid, gasoline or gum rubber and a catalyst activating agent such as an ester of monocarboxylic acid, a straight chain hydrocarbon or an aromatic hydrocarbon.To control the temperature of the gas generator apparatus an electronic temperature controller circuit is used in the reaction chamber.
