A bicycle seat with inflatable interior including a bicycle seat comprised of a seat portion and a stem portion. The stem portion couples the bicycle seat to a frame of a standard bicycle. The seat portion has an outer layer and a padded inner layer. The padded inner layer has a recess formed in a central portion thereof. An inflatable cushion is disposed within the recess formed in the central portion of the padded inner layer of the bicycle seat. The inflatable cushion has a generally hourglass configuration. The inflatable cushion has an air tube extending outwardly therefrom and extending outwardly of the bicycle seat. A free end of the air tube has a hand pump coupled thereto for selectively pumping air into the cushion.

Bicycle seat with inflatable interior

Method and apparatus for curing a tire having an internal cavity using as heat and fluid pressure media first steam and then cooler inert gas. The time rate of pressure loss in the cavity is determined in each tire curing cycle by closing the cavity so as to form a completely closed chamber for a test time less than the normal cure time for the tire. Pressure loss during the test time is monitored and if determined to be at a greater than tolerable rate a warning device is actuated and means for loading a next tire into the mold is rendered inactive.
