摘要:
A cleaning implement for removing particulate soils from a compressible resilient surface is provided.The cleaning implement includes a ramp for pressing particulates against the compressible resilient surface and a collection member for collecting the particulates which are projected away from the compressible resilient surface when the cleaning implement is moved across the compressible resilient surface.

A tire pressure indicator that is combined with a fill valve. The indicator and the fill valve are coaxial or concentric. The invention may be screwed onto a tire valve stem. The indicator has three bands or sections, each of which is a different color, for indicating whether tire pressure is within a predetermined range, above that range, or below that range. The colors are viewed through a lens, aided by a mirror. A diaphragm pushes the indicator up when pressure rises, while a spring pushes the indicator down when pressure drops. A tire may be inflated or deflated while the invention is mounted on a tire stem. During inflation, the pin in an air chuck at the end of an air hose may depress a valve pin assembly to open the fill valve. A user may deflate the tire by manually depressing the valve pin assembly to release air.

摘要:
An inflation stem having an inflation valve combined with a blow-off valve to prevent overinflation. The valves are forced open during inflation when the actuating pin is depressed by the compressor chuck head, opening a fill chamber through which fluid flows into an inflatable object, and also opening a blow-off chamber. A blow-off intake allows lower pressure fluid from the interior of the object to enter the blow-off chamber. The fluid entering the blow-off chamber is isolated from the high pressure fluid coming in from the compressor through the fill chamber by a separation fin and shield joined to the bottom end of the actuating pin. A blow-off gasket is biased upward by a blow-off spring. But as pressure in the object and the blow-off chamber increases, the blow-off gasket is forced down, until at the predetermined pressure it is pushed past a blow-off port, through which fluid then escapes.
