摘要:
A wheel assembly includes a tire, having each bead seat angle in the range of 10 degree to 12 degree with respect to the axis of rotation, preferably 11 degree, and an aspect ratio of less than 60%, and a wheel rim, having a circumfurential well and a bead support surface angle also in the range of 10 degree to 12 degree, each bead support surface terminating in an upstanding flange overlapping a radially inner portion of the tire to support the sidewall of the tire. The flanges may be part circular in cross section defining a segment of approximately 135 degree, the radius of curvature being greater than 0.5 inches and preferably 0.75 inches.

A system for extracting odors is disclosed. The system comprises a toilet having a bowl with an upper rim. The bowl can be configured to contain water in the bottom of the bowl. A flush opening in the bottom of the bowl can be configured to enable water to be evacuated from the bowl through the flush opening. The system further comprises a ventilation conduit extending between the bowl and drain. The ventilation conduit comprises an upper wall and a lower wall. The lower wall of the ventilation conduit can extend above the upper rim of the bowl. The system also comprises a negative pressure unit. The negative pressure unit can be configured to draw air from the bowl through the ventilation conduit and into the drain.

An aerosol container cap and activator button assembly is provided having a housing portion designed to mount on one end of an aerosol container with a tight friction fit. The housing has a bore therethrough defined by an interior wall with an activator button rotatably and slideably mounted within the bore. The activator button has a detent formed on the lower portion to engage the housing bore to keep the button secured within the housing. The button has a dispensing nozzle orifice formed therein as well as a positioning member formed on the top opposite the orifice to facilitate movement from a dispensing to a non-dispensing position. The assembly has positive stops to limit rotation of the button between the dispensing and non-dispensing positions.
