Abstract: An intragastric device includes an elongated member having a proximal end and a distal end and an anchor connected to the elongated member. The anchor includes a stem, a first arch and a second arch, and a curvilinear element. The stem includes a proximal end and a distal end. The distal end of the stem is attached to the proximal end of the elongated member. Each arch has first and second ends and a proximal peak therebetween. The first end of each arch is attached to the proximal end of the stem, and the second end of each arch extends radially away from the stem. The curvilinear element connects the second end of the first arch to the second end of the second arch.

Abstract: A battery housing has a plurality of housing sidewalls defining an enclosure, where a first housing sidewall of the plurality of housing sidewalls defines a plurality of openings cumulatively defining a valve opening. The housing defines a valve coupling structure around the valve opening.

Abstract: A machine adapted to be maneuvered across a surface, typically a floor, in order to remove an unwanted coating such as asbestos and adhesive from the floor. An impeller hurls an abradent such as metal shot at an angle against the floor abrading the material which then rebounds along with the abradent up into a return channel where the abradent shot and the abraded material are separated. The shot is returned to the impeller. The abrasion takes place in a downward facing cavity. A wetting spray outside the cavity in advance of the forward end of the machine wets the surface in advance of the abrasion and creates a mist within the cavity which cools the flow of material rebounding from the surface. The presence of the mist greatly abates the dispersion of the abraded material permitting it to be discharged into a collecting drum without contaminating the ambient air.
