Abstract: The positionable towing hitch includes a first beam supporting a movable housing assembly and a second beam assembly movable in the housing. The first beam protrudes out of the housing for mounting to a hitch receiver of a vehicle. A first beam driver assembly is coupled to the first beam to selectively extend and retract the housing with respect to the first beam in a horizontal direction. A second beam driver assembly is coupled to a second beam to selectively raise and lower the second beam with respect to the housing in a vertical direction. A ball mount bracket is fixed to the second beam for mounting a ball mount thereon to move with the second beam. The movements of the housing and the second beam facilitate positioning of the ball mount for connection to a trailer to be hitched.

Abstract: The multistage aeration system includes a water jet tank system having a closed water tank that holds a pool of water and seals in air above the pool of water. A nozzle in the top portion includes air bleeder passages to allow an ambient air to flow through the nozzle and into the closed water tank. A water flow meter and a water pump circulate water from the closed water tank to outside the tank through the water flow meter and then through the nozzle. The nozzle entrains air through the bleeder passages into the water as the water passes through the nozzle, and forms a jet spray into the pool of water. An air flow meter valve and a closed water tank air outlet pipe extend from the closed water tank and connect the water jet tank system to a diffused aeration tank system with a series tank system.

Abstract: A water desalination system and process are provided in which a suspension is fed into a water desalination chamber from a source container. At least one effervescent tablet is introduced into a base fluid within the source container to form the suspension. The effervescent tablet serves to increase the heat absorption of the base fluid and enhance the efficiency of the water desalination process. The effervescent tablet used in the process may include multi-walled carbon nanotubes (MWCNT) as well as one or more surfactants and/or effervescent agents such as sodium dodecyl sulfate, monosodium phosphate, and sodium carbonate. Introduction of the effervescent tablet into the base fluid may result in the growth of crystals within the suspension. The presence of crystals in the suspension serving to further enhance the solar radiation and heat absorbance of the base fluid.

Abstract: An effervescent suspension for metallic quenching and coating purposes, is implemented by providing and an effervescent tablet with mixture comprising a solid alkaline, a solid acid, and noble metal particles. The mixture is added to water to produce a reaction in the water resulting in the release of CO2 gas, which disperses the noble metal particles in the water to provide a suspension. A hot metal material, having a temperature below its melting point, is immersed in the suspension to provide a quenched metal that has a temperature below its melting point in the suspension to provide a quenched metal coated with noble metal particles. The solid alkaline may comprises sodium bicarbonate (NaHCO2) powder and sodium carbonate (Na2CO3) powder. The solid acid may comprise monosodium phosphate (NaH2PO4) powder.

Abstract: The amusement ride for children has an open frame and a swinging passenger carriage suspended from a crossbar carried by two trolleys mounted in parallel tracks on the roof of the open frame. The passenger carriage has an upper platform rotatably mounted on a base platform, rotation of the upper platform being controlled manually by the passenger through rotation of a wheel mounted on a column having an end journaled into a bearing mounted in the base platform. A reversible motor is mounted on the roof frame, the shaft of the motor being connected to the crossbar by a crank and connecting rod to control translational movement of the trolleys, causing the passenger carriage to swing forward and backward. The combination of translational movement and swinging movement of the carriage with rotational movement of the upper platform provides a uniquely thrilling sensation for a child seated on the passenger carriage.

Abstract: The core sample holder for microwave heating of a core sample includes a hollow housing having opposed open first and second ends. A resilient sleeve is disposed within the hollow housing. An annular bladder is disposed within the hollow housing and surrounds the resilient sleeve. The annular bladder is adapted for receiving a liquid. An annular cavity is defined between the outer surface of the annular bladder and the inner surface of the hollow housing and is adapted for receiving a pressurized fluid through at least one pressurized fluid port. First and second caps releasably cover and seal the first and second ends of the hollow housing, respectively. A microwave waveguide passes through the wall of the hollow housing and the annular cavity for transmitting microwave radiation from an external microwave source into the liquid contained within the annular bladder to heat the liquid.

Abstract: The system and method for determining physical stability of dispersed particles in flowing liquid suspensions is performed by passing a fluid with suspended particulates in a column of filter elements having progressively smaller porosities. The fluid is received by a fluid supply receptacle and then passed through the column of filter elements. The filter elements are arranged so that successive filters are downstream of each other, with successive filters having successively smaller porosities. The porosity of an initial filter element has a sufficiently large porosity to filter a largest particle size intended for detection, and a final filter element has at least a sufficiently small porosity to filter a smallest particle size intended for detection. This results in the successive filters separating successively smaller particles from the fluid. Average particle size and particle count are obtained by removing a mesh filter element and performing SEM analysis on the filtered particles.

Abstract: A multi-heat energy source core sample holder assembly for conducting experiment on a core sample includes a core sample holder, a flexible sleeve, and a multi-heat energy generation source arrangement. The core sample holder includes a cylindrical pressure chamber and a pair of disk-shaped flanges positioned along opposite ends of the cylindrical pressure chamber to accommodate at least one fluid injection port and at least one fluid discharge port. The flexible sleeve is arranged within and along the cylindrical pressure chamber to define one or more section(s) to hold the core sample. The energy generation source includes a wire member to be coiled along an internal wall of the flexible sleeve to be supplied with electric current in at least one of a Direct Current (DC) form to produce an electric resistance heating, or an Alternate Current (AC) form to produce an electromagnetic heating, singularly or in combination.
