Abstract: A hookah assembly for smoking is provided comprising an outer chamber having a smoke outlet and an inner chamber for containing a liquid. The inner chamber is enclosed within the outer chamber and an interim chamber is provided within the outer chamber and outside of the inner chamber. Also provided is a smoke conduit for transmitting smoke from a smoke source into the inner chamber below a fill level of the liquid. The inner chamber is in fluidic communication with the outer chamber above the fill level of the liquid and the inner chamber and the outer chamber are not in fluidic communication with the interim chamber. Smoke is drawn from the inner chamber to the outer chamber when smoke is drawn from the smoke outlet. Also provided is a liquid chamber assembly for use in an existing hookah.

Abstract: Tongs are provided, where the tongs have a pair of tong arms each having a first end and a second end. Each tong arm comprises a substantially cylindrical hinge component at the first end formed from a structural material and a gripping component at the second end formed from the structural material. A handhold extends from the hinge component to the gripping component and is formed from a handhold material, and a substantially linear linking element extends from the hinge component to the gripping component of the corresponding tong arm. The linking element is formed from the structural material. The structural material is stronger than the handhold material, and the linking element is surrounded on at least three sides along its length by the handhold.

Abstract: A filter assembly has an outer housing having an open first end and an open second end. An inner filter housing is within the outer housing adjacent the second end, and a gasket is provided at the first end of the outer housing. An internal chamber is provided between the first end of the outer housing and the inner filter housing, where during use, fluid from the within the internal chamber is drawn out the second end of the outer housing by way of the inner filter housing. A filter is provided within the inner filter housing. The gasket forms a gasketed opening smaller than the open first end of the outer housing. The gasket may extend axially adjacent a wall of the outer housing and abut the inner filter housing, such that the internal chamber is defined by the gasket and the inner filter housing.

Abstract: Systems, methods, and devices for heat management of heating implements for a water pipe.

Abstract: A heat management system, device, and method are provided for a system for facilitating smoking of tobacco from a hookah having a bowl with an interior space for holding organic matter to be smoked by a user. An electric heating head is provided for resting on the bowl, the electric heating head having a heating element, a screen located between the heating element and the bowl when the heating head is rested on the bowl, and a lower air gap between the heating element and the screen.

Abstract: A device is provided to inspect welds in nozzles located in water within a containment vessel of a nuclear power plant. A computer connected to the device controls movement by use of thrusters located along a main rail while buoyancy packs regulate the depth. After the device is navigated to a weld needing inspection, feet extend radially outward from the main rail to secure the device in the nozzle. Then transducer clusters are moved along the main rail to be radially inside the weld to be inspected. Thereafter, the transducer clusters are extended radially outward and rotated adjacent to the weld while simultaneously emitting test signals and receiving reflected signals to indicate the condition of the weld.
