The present invention relates to a painting booth having a structure which sprays a paint in a painting booth, and is capable of reutilizing by withdrawing a used paint, and preventing atmospheric pollution and surrounding contamination, and is configured to include: an exhaust duct installed in an upper part of a booth; a filter plate configured by a metal net, which is installed on a front wall of the booth; a bottom filter plate installed on a bottom of the booth, and a collector collecting paint sludge which falls to the bottom.

Methods and compositions for cleaning industrial equipment (e.g. biofuel or corn ethanol plant equipment) in place at high temperatures using acidic methane sulfonic acid compositions having a low pH.

An apparatus for steam treatment of a carrier head or a substrate in a chemical mechanical polishing system includes a load cup, a pedestal in a cavity defined by the load cup, the pedestal configured to receive a substrate from or supply a substrate to a carrier head, a boiler to generate steam, one or more nozzles positioned to direct steam inwardly into the cavity defined by the load cup, and a supply line running from the boiler to the one or more nozzles to supply steam to the one or more nozzles.

A roasting and glazing apparatus includes a roaster, an agitator mounted within the roaster bowl for mixing a mixture of nuts and sugar during a roasting or glazing operation, a heater controlled to heat the roaster bowl during the roasting or glazing operation, and a cover removably mounted to the roaster bowl. The cover includes a reservoir for receiving water from a user and restricting water flow from the reservoir into the mixture of nuts and sugar in the roaster bowl. The cover and the roaster bowl together define a vent on a side of the cover opposite the reservoir. The vent is configured to direct steam out of the roaster bowl in a direction away from the reservoir.

The present invention relates to a cleaning apparatus comprising steam having an induced cyclonic rotation emanating from a tapered nozzle. Specifically, the present invention comprises an element within a tube near or otherwise adjacent to a tapered nozzle from which steam emanates. As the steam passes the element, a rotation is induced in the steam causing it to rotate upon exiting the tapered nozzle. The induced cyclonic rotation of the steam exiting the tapered nozzle of a cleaning apparatus aids in the cleaning of objects. In an exemplary embodiment, the steam cleaning apparatus is a jewelry cleaning apparatus.

A method of roasting nuts comprises placing water and a mixture of nuts and sugar in a roaster bowl, mixing the water and mixture, heating the roaster bowl during mixing to roast and sugar coat the nuts, covering the roaster bowl with a cover after roasting and sugar coating, adding water to a reservoir disposed within the cover wherein the reservoir includes at least one metering hole, flowing through the metering hole, from the reservoir to the roaster bowl, the water added to the reservoir, glazing the nuts during the flowing of water into the roaster bowl from the reservoir, and removing the cover from the roaster bowl after glazing the nuts. The measured flow of water through the reservoir results in well coated glazed nuts and prevents the formation of a large burst of steam, thus protecting the operator against being scalded during glazing of the roasted nuts, as well as providing other benefits.

A method and a system for cleaning a machine for making liquid and/or semi-liquid food products for the ice cream, pastry or catering trade, wherein the machine is fed with a capsule containing a preparation for cleaning the machine, after which a cycle for cleaning the machine is started.

The present invention relates to a painting booth having a structure which sprays a paint in a painting booth, and is capable of reutilizing by withdrawing a used paint, and preventing atmospheric pollution and surrounding contamination, and is configured to include: an exhaust duct installed in an upper part of a booth; a filter plate configured by a metal net, which is installed on a front wall of the booth; a bottom filter plate installed on a bottom of the booth, and a collector collecting paint sludge which falls to the bottom.

A mobile decontamination system has an internal combustion engine, a generator, a first pump, a boiler and a second pump. The engine is coupled to the generator and to the first pump. The first pump is designed for discharging a first decontamination medium via a first spray lance. The second pump is designed for discharging a second decontamination medium via a second spray lance. A system controller is designed for selectively operating the first pump and the heating boiler in one of at least two different operating modes. In the first operating mode, the first pump delivers a first volumetric flow through the boiler which is at such a high level that the first decontamination medium is in liquid form. In a second operating mode, the first pump delivers a second volumetric flow through the boiler which is at such a low level that the first decontamination medium transfers into gaseous form.

The present application describes apparatus for removing powder from a powder-based additively manufactured part, comprising at least one chamber (106) to contain a fluid, a device to induce flow in the fluid to agitate and remove powder from a powder-based additively manufactured part located therein, and an ultrasound generating transducer (121) to produce ultrasonic waves in the or a further fluid and agitate and remove powder from the powder-based additively manufactured part located therein. Methods of removing powder from a powder-based additively manufactured part and a method of cooling a powder cake supporting a powder-based additively manufactured part are also described.
