A method of fabricating semiconductor devices includes: loading one or more semiconductor wafers into a plurality of stations provided within a process chamber; applying a process to the semiconductor wafers which deposits a material on the one or more semiconductor wafers within the process chamber; and cleaning the process chamber. Suitably, cleaning the process chamber includes flowing a cleaning gas into the process chamber toward a deflector arranged in the process chamber, the deflector having a first surface upon which the flowed cleaning gas impinges, the first surface directing a first portion of the flowed cleaning gas impinging thereon in a first trajectory toward a first end of the process chamber and directing a second portion of the flowed cleaning gas impinging thereon in a second trajectory toward a second end of the process chamber, the second end being opposite the first end.

A cleaning brush for cleaning containers of complex design, wherein the cleaning brush can reach hard-to-reach areas of the container. The cleaning brush includes a twisted wire and a cleaning head coupled to the twisted wire. Portions of the twisted wire and the cleaning head have bristles. The cleaning head can flex sidewards relative to the twisted wire.

Installation provided with at least one high-pressure circuit comprising at least one high-pressure pump and rotating nozzles attacking the four sides of crates in order to automatically remove labels, wherein the installation further comprises a low-pressure circuit able to clean the installation inwardly and to transport labels to specific filters so that stoppages are diminished and further able to recirculate the water of the high-pressure and low-pressure circuits, and wherein trolleys holding the crates are able to rotate by means of a predefined path on perimetral guides of the frame so that the jets of the nozzles attack the required walls of the crates on four sides.

A wash ring for cleaning a tank. The wash ring comprises a curved surface having an inner edge and an outer edge. The wash ring further comprises an inner wall having a first height and an outer wall located between the inner end and outer end and having a second height that is less than the first height. A plurality of notches is located at the outer edge of the curved surface. The wash ring has a feed pipe with an outlet located between the inner wall and outer wall.

The invention relates to an apparatus for treating foodstuff containers by spraying with a biocide-containing treatment liquid in at least one treatment zone (Z1-Z4) equipped with spraying means (B) for spraying the containers, the apparatus further comprising transport means for transporting the containers through the treatment zones (Z1-Z4), at least one generator (G1) for producing a biocide solution, at least one heating device for heating the treatment liquid, lines for supplying the biocide solution from the generator (G1) to the treatment zones (Z1-Z4) and, optionally, to at least one further biocide consumer device (BV1, BV2), lines for supplying the treatment liquid to the treatment means (B), as well as valves (V1-V7), controllable metering devices and pumps required for controlling the liquid flows, characterized in that a) the apparatus comprises at least two generators (G1, G2) for producing the biocide solution, and b) the generators (G1, G2) are connected or connectable neither directly nor indirectly to one another, but via corresponding feed lines to all treatment zones (Z1-Z4) and to any further biocide consumer device (BV1, BV2); and a method for operating such an apparatus.

A portable spray cleaning system with a device for sanitizing the interior surface of residential trash cans. The device includes adjustable arms, a plurality of spray nozzles, and rubber clamps. On one end, the device may also include a port for connecting to a water supply via a hose. Once the hose is connected, water can then be sprayed out through the spray nozzles. The pressure created by the water flow enables the device to rotate while water is being sprayed. There may also be a compartment for inserting a disinfectant that mixes in with the water. The device is collapsible for easy storage and packaging. It is known that trash receptacles often become very dirty and contaminated after repeated use.

Disclosed herein are various embodiments of container washing systems and methods. The exemplary systems may include a foot valve, the foot valve having an input for a fluid, a tray having a grate, the grate configured to support the container; and a rotatable assembly having one or more nozzles, wherein actuation of the foot valve opens a fluid path from the foot valve to the nozzles, such that a fluid may be sprayed above the tray and into the interior of the container.

Various embodiments include methods and chemistries to etch metal-oxide films. In one embodiment, a method of etching tin oxide (SnO.sub.2) films includes using thionyl chloride (SOCl.sub.2) chemistry to produce an etch rate of the SnO.sub.2 films of up to 10-times higher as compared with Cl.sub.2 chemistry for similar flow-rates and process conditions, and gettering oxygen species from the SnO.sub.2 films by using the SOCl.sub.2, thereby forming volatile SO.sub.2 and volatile SnCl.sub.4 to provide human safety and machine safety and operations. Other methods, chemistries, and techniques are disclosed.

Systems, devices, and methods for passing railcar tank cleaning systems through the opening and mounted to existing manways. The invention can extend horizontally more than 25 feet and clean rail cars up to and beyond approximately 102 inches in diameter for manual, automated, or semi-automated programmable railcar tank cleaning systems, devices and methods for providing safe and efficient methods for breaking up oil, tar, chemical, radioactive, hazardous, or any other liquid, solid, or sludge waste inside rail tank cars and the like with nozzles which utilize fluid jets to break up, liquefy, and motivate tank material. The programmable railcar cleaning system can be a standalone, independent unit or integrated into new designs and/or existing systems. Simplified programming and user interface allow an operator to remotely operate the system. The various capabilities of this invention allow cleaning in a quicker and more efficient manner. The system is hydraulically controlled and can work in the presence of flammable vapors and dust.
