An ultra-lean dilution apparatus is provided for proportioning minute quantities of a first fluid, such as a concentrated cleaning solution, for mixing into a second fluid, such as tap water, which provides improved performance and which can be manufactured by assembling several molded components with little or no machining. The dilution apparatus (20) provides a selective pressure drop in a conduit (22) by including a plurality of dilution disks (50a-50f), each dilution disk (50a-50f) having a tortuous path (52a-52f) of sufficient cross-sectional area to be resistant to clogging and having a sufficient number of sharp turns to create a desired pressure drop. While each disk (50a-50f) produces a predetermined drop, the serial configuration of the tortuous paths of the plurality of dilution disks is additive to produce a range of dilution suitable for the chemicals used. Advantageously, the tortuous path of a first of the plurality of dilution disks (50a) is recessed into a front face so that bringing the front face (54a) of the first dilution disk (50a) in contact with a back face (55b) of a second dilution disk (50b) completes the tortuous path (52a). Furthermore, a blind intake (58a) of the tortuous path (52a) of the first dilution disk (50a-50f) selectively communicates with an output port (56b) of another tortuous path (52b) on a front face (54b) the second dilution disk (50b).

A process for the conversion of carbohydrates from any of a number of sources into butanol and hexanol for fuel or chemical use is disclosed. The process includes conducting a homoacetogenic fermentation to produce an acetic acid intermediate which is chemically converted to ethanol.

An independent and conserved source of fuel and / or power comprises a top stage rocket engine firing up to 5000 F. at very high pressures, delivering jet flows up to transonic velocities into a near adiabatic tunnel for mixing in general and / or for transforming reactants introduced to suit specific objectives. The related compression is supplied by an independent prime mover which compresses its exhaust and other recoverable fluids. Low grade flows, thereby upgraded in temperature and pressure, are adiabatically contained, are further upgraded in the tunnel to become part of the prescribed fuel for export at the tunnel ends; or fuel to be fired in a prime mover for electric or other power, or hydrogen for chemical use. Expansion turbines for this purpose are relieved of the load used to compress the excess air in standard gas turbines thus increasing export power. A portion of the expansion turbine's exhaust becomes part of recoverable fluids. When oxygen is used instead of air, the gases through turbines are nitrogen-free with more heat capacity reducing turbine inlet temperatures for the same power. When reactant transformation is specified, the larger water vapor content in the cycle enhances the water gas / shift autothermally for ammonia and / or power and alternatively for pyrolysis cracking for olefins and diolefins. Further, staging rocket engine reactors increases efficiency in boilers and steam turbines; and staging can produce sponge iron and / or iron carbide as well as expansion turbine power and fuel cells for peak and off-peak loads.

The microorganism can be Clostridium autoethanogenum, Clostridium ljundahlii or Clostridium ragsdalei.

The invention discloses a PVC material and a preparation method thereof. The PVC material comprises the following substances according to parts by weight: 100 parts of PVC, 2-8 parts of stabilizer, 2-6 parts of processing agent, 1.5-2.5 parts of lubricants, 4-12 parts of filler, and 0.05-1 part of colorant.

An immersion processing system is provided for cleaning wafers with an increased efficiency of chemical use. Such a system advantageously uses less cleaning enhancement substance that may be provided as gas, vapor or liquid directly to a meniscus or wafer / liquid / gas bath interface so as to effectively modify surface tensions at the meniscus with minimized chemical usage. Such a delivery system design may be applied for single wafer processing or for processing multiple wafers together within a single liquid bath vessel. For single wafer processing, in particular, cleaning enhancement substance can be delivered along one or both major sides of the wafer, preferably at the meniscus that is formed as the wafer and liquid are relatively moved, while a processing vessel usable for such single wafer processing may itself be designed with a minimized size to accommodate a single wafer. By reducing the vessel volume, chemical usage for any processing chemicals that are to be provided within a liquid bath may also be advantageously reduced.

Remote monitoring of vehicle washing facilities allows a facility operator to more efficiently manage each site, particularly when combined with environmental conditions that influence the rate at which individual chemicals are used. Accurate chemical exhaustion times can therefore be predicted and communicated to the operator, and wash sequences and parameters may be altered in accordance with such environmental parameters. For example, information related to the composition of soil on a car may be monitored and used to alter the chemicals used in the wash cycle for that car. Other environmental conditions may include without limitation weather conditions, road conditions, types of vehicles, mechanical system status, vehicle temperature, etc.

The present invention provides a steam cleaning system comprising a housing and a steam generating system for producing a low pressure, superheated saturated steam. A steam dispensing system comprising a water reservoir and a pump feeding the water into a steam producing boiler, is coupled thereto for dispensing the steam from the system to at least one first outlet port. A cleaning solution dispensing system is provided, having at least one reservoir for a cleaning solution, and a pump system for dispensing a predetermined amount of a cleaning solution from said at least one reservoir to at least one second outlet port. The at least one first and second outlet ports are positioned adjacent one another, such that a mixture of cleaning solution and saturated steam at a low pressure and low volume of steam and cleaning solution is dispensed from the system. The present invention is particularly suited to clean objects off the floor, vertical surfaces such as glass, and small areas of floor. Because of the small volume of water and chemicals used, it can be used indoors, as well as mounted on mobile platforms such as trucks, buggies, utility vehicles, automatic floor scrubbers or the like. The system also provides for cleaning of roads, sidewalks, exterior structures, or for spot cleaning or cleaning of surfaces in difficult environments. The low pressure, superheated, saturated steam cleaning assembly of the present invention provides low pressure (10 Bar) operation, and relies upon superheated steam temperatures coupled with environmentally friendly chemicals as an abrasive force, thus avoiding any collateral damage usually caused by the high pressure output. The present invention only applies 3 to 10 gallons of water an hour, depending on the size of the machine, while a conventional high-pressure washer / steamer will use 240 gallons per hour.
