Abstract: A hard hat adapter for a welding helmet is disclosed. The dapater includes a housing which has an outer wall, an interior surface and a bottom surface. The outer wall includes a surface defining a window therethrough. The interior surface includes a recessed surface circumscribing the window. The recessed surface includes at least one planar surface thereon. A rotatable boss is captured within the housing against the interior surface. The boss has an annular lip that includes at least one planar surface thereon configured to selectively engage the planar surface on the recessed surface of the housing and prevent the boss from rotating when engaged thereon and freely rotatable when disengaged therefrom. A mounting post extends from the boss and projects through the window on the housing. The mounting post is configured to selectively couple to a welding helmet. The welding helmet may include a rotatable cam configured to engage a lever arm on the hard hat adapter.

Abstract: An electrical appliance housing is disclosed having a housing with an open side portion and an open front portion adjacent and perpendicular to the open side portion. A removable end panel is provided to fit within the open side portion of the housing and may include an elastically deformable detent mechanism on the side edges of the end panel to temporarily lock it to the housing. An interchangeable modular component is provided within the housing for establishing the function of the electrical appliance housing. The electrical appliance housing function may include air conditioning, air moving, light emitting, infrared light emitting or any other function desirable in a ceiling or wall appliance. The modular components are interchangeable, such that the function of the electrical box may be changed at any time by interchanging the modular components within the housing to the desired set-up.

Abstract: Apparatus for selectably buttering and salting an article of food such as an ear of corn or the like. A separate butter receptacle and salt receptacle are pivotably interconnected with each other so that the salt receptacle can fit into an opening of the butter receptacle, thereby urging a chunk of butter through a dispensing opening to be spread onto the corn. After the corn is buttered, the buttering and dispensing apparatus may be inverted in position to salt the corn.
