The specification discloses an improved pressure cleaning system (10) which is adapted to facilitate complete purging of air and thus priming of the system in minimal time, and which incorporates all mechanical or electrical components constructed and arranged so as to be suitable for use in hazardous areas. The cleaning system (10) includes a float entry tank (20) connected via a U-shaped conduit (38) to a pump (42) located at substantially the same level as the tank. An electrical heater tank (88) is connected to the pump (42) and is located beneath the pump. A flow sensor (28) on the inlet to the float water tank (20) and temperature sensor (132) on the heater tank (88) are provided for sensing conditions which could lead to overheating and thus premature burnout of the heating elements in the heater tank. The controls are responsive to the flow sensor (28) and temperature sensor (132).

A spiral fluid heater coil system for facilitating drainage of fluid from the heater and increasing the efficiency of transferring heat to a fluid. The spiral fluid heater coil system includes a heater assembly including a combustion chamber having a chamber perimeter wall defining a chamber interior. The chamber perimeter wall has an upper end and a lower end, with the upper end of the chamber perimeter wall defining an opening into the chamber interior. The heater assembly includes a burner apparatus for burning fuel and expelling heat into the chamber interior of the combustion chamber, with the burner apparatus being positioned adjacent the lower end of the chamber perimeter wall for directing heat upwardly in the chamber interior toward the upper end of the chamber perimeter wall. The heating assembly includes a heating conduit for moving fluid through the heater housing to heat the fluid. The heating conduit has a heating portion positioned adjacent to opening in the upper end of the chamber perimeter wall of the combustion chamber for permitting heat from the chamber interior to pass through the heating portion of the heating conduit.

A new support frame for supporting a cleaning device. The inventive device includes a base having a pair of spaced apart elongate side bars and spaced apart elongate first and second end bars. The end bars of the base are extended between the side bars of the base. The base has ground engaging members downwardly depending therefrom. The frame also includes first and second end members with each end member having a pair of elongate lower arm portions and an elongate upper cross portion. An upper mounting assembly is spaced apart from the base and is interposed between the base and the upper cross portions of the end members. Elongate first and second upper bars are extended between the arm portions of the first end member and are interposed between the upper cross portion of the first end member and the first end portion of the upper mounting assembly. A handle member is extended from the first end member away from the second end member. A pair of spaced apart elongate mounting brackets are coupled to the upper mounting assembly and to the upper cross portion of the second end member.

122328

A low pressure steam generator including a water tube structure of plural, substantially annular coaxial portions each connected individually by separate conduits to a steam header above and a water header below. The portions coact with suitable baffle means to comprise a combustion chamber, but are significantly spaced to allow combustion products to pass between them from a burner directing a flame axially within the chamber, and the greater part of the combustion products are directed upward by the baffle means to bathe the steam header outside the combustion chamber as well. Means are provided for maintaining the water to be vaporized at a suitable level, and the whole is enclosed in a suitable housing to the top and bottom of which the headers are secured. The tube structure may be a continuous helix or an array of discrete annuli.

Mechanism for controlling flow of cleaning fluids under pressure to a discharge nozzle of cleaning apparatus using steam or hot water for industrial cleaning purposes. A control valve for controlling flow of the cleaning fluid is operated by other fluid introduced thereto by an automatically closing manually opened valve. The control valve is arranged to close gradually when the manually opened valve is permitted to close, to prevent shock loads in the fluid system.

A venturi-type ejector for delivering cleaning liquid to an article to be cleaned and having cold and hot liquid inlets; a high pressure pump for delivering cold liquid to the cold liquid inlet; a boiler for heating liquid and having an outlet for connection to the hot liquid inlet; and a low pressure pump for delivering liquid to the boiler. A pair of motors are connected each to a different pump and are controlled to cause cold or hot fluids to be delivered to the ejector for ejection therefrom separately or together, selectively. Control elements are included for controlling operation of the boiler responsive to flow of liquid to the boiler and to temperature of fluid discharged from the boiler.

A new encapsulated heating element fluid heater for heating a fluid such as water. The inventive device includes a vessel and an end cap. The end cap has a plurality of bores therethrough extending between the first and second ends of the end cap. A plurality of elongate heating element rods extend through the bores of the end cap and each heating element rod has a heating portion outwardly extending from the first end of the end cap and an electric coupling portion outwardly extending from the second end of the end cap. The first end of the end cap is inserted into an open end of the vessel such that the heating portions of the heating elements extend into the vessel. The end cap is then welded to the end of the vessel.
