Abstract: A mobile apparatus for cleaning sewers, catch basins and the like includes a debris collection chamber mounted on the rear of a vehicular chassis. A vacuum conduit communicates with the chamber and is adapted to be lowered into the sewer. A vacuum fan also communicates with the chamber and draws air through the conduit and chamber thereby picking up debris from the sewer. As the debris enters the chamber, the configuration thereof creates a rapid decrease in the air flow velocity and otherwise interrupts the flow so that material entrained in the air is deposited in the chamber. The configuration of the chamber also permits facile discharge of the debris out of the bottom of the chamber in that one end wall of the chamber is swingable to open the bottom thereof. This same end wall also carries a hose reel for use in flushing the sewer. Because the debris which is picked up may well include water, means are provided to drain the water from the chamber.

Abstract: A self-service, wet-vacuum cleaning machine for carpets, upholstery, and the like, utilizes a hand-held tool attached to both a vacuum hose and a hot water hose. A motor driven pump operates for a metered time to provide hot water under a high pressure in a direction that closes a valve in the hand tool to prevent spraying until it is called for by manually unseating the valve, thus allowing hot water to be sprayed on an area to be cleaned by wet-vacuuming. A spring in the valve housing exerts a force against the valve in a direction to unseat it, but not with sufficient force to do so against the hot water pressure. When the hot water pump is turned off, cold water under line pressure enters the hot-water hose through a T-fitting at a controlled low rate and passes through the valve now opened by the spring. This flow at a low rate prevents freezing in the hot water hose or spray valve.

Abstract: A moisture stripping device for non-evaporatively stripping moisture from a moving film such as a photographic motion picture film.
