The apparatus 1 comprises a detecting means 11 for detecting a shape of the molding surface 4, a cleaning means 12 for cleaning the vent hole 5, a controlling means 13 for storing molding surface information in advance and including shape information of the molding surface 4 including a position of the vent hole 5 and for calculating the position of the vent hole 5 by comparing the shape of the molding surface 4 obtained by the detecting means 11 with the molding surface information, and a guiding means 14 for moving the cleaning means 12 based on the calculated position of the vent hole 5.

A system and method for treating a portion of a food flow path in a food processor having a freezer chamber includes imparting a continuous flow of solution through a portion of the food flow path with sufficient flow rate, temperature and flow duration to impart at least one of (i) impart at least a 6 log reduction in inoculum count and (ii) extend the necessary time for manual cleaning of the portion of a food flow path exposed to the continuous flow of solution to at least 7 days.

When an alkali-free glass is polished with a polishing liquid containing hydrofluoric acid as a main component, a sludge is generated on a glass surface and in a storage unit and a pipe of a polishing device. As a result, there arise problems such as deterioration of quality and stopping of the device. A washing liquid that dissolves a sludge containing aluminum and fluorine produced in a glass polishing device is characterized by containing Al3+ ions, and a sludge formed by bonding a divalent element such as Mg, Ca, Sr, and Ba with Al and F can be dissolved with this washing liquid. The problems are solved by washing the inside of the polishing device with this washing liquid.

In a method of removing scale deposits from a used oilfield tube having first and second threaded ends, a coupling collar is unscrewed one or more rotations from a first threaded end about a longitudinal axis of the oilfield tube without detaching the coupling collar from the first threaded end. A spray of water is discharged through a spray tip of a lance. The spray tip is fed along the longitudinal axis from the collar to the second threaded end using a lance feeder, wherein the spray tip travels through a bore of the collar and the interior of the oilfield tube. Scale deposits are removed from the bore of the collar and the interior of the oilfield tube using the spray of water during the feeding of the lance.

A valve body with conduits on opposing sides having attachable pressure cover-plates and valve servicing assemblies that can be selectively installed onto the valve body while it is fully pressurized. The valve body includes simple isolators that allow access openings to be blocked and exposed that allow various style operating mechanisms and tools without the need for intermediate isolating mechanisms. Attachable subcomponents can provide pressurized fluid that is injected into the valve body from an external power source to move sand and debris away from seating surfaces while advancing and retracting various style gates.

This invention relates to cleaning the induction systems, the combustion chambers and exhaust systems of internal combustion engines. And, more particularly, to chemicals and mixtures of chemicals for removing the different types of carbon deposits encountered in internal combustion engines used in road vehicles. Carbon deposits were taken from the induction systems of these road vehicles for the purpose of bench testing such carbon and product development. More specifically, chemicals (i.e., solvents) and chemical mixes (i.e., solutions) have been accurately tested on such harvested carbon deposits for their ability to remove the various types of carbon deposits that accumulate within road vehicle internal combustion engines. Additionally this invention also relates to apparatus for delivering chemicals and chemical mixes. Which includes those developed by applicant, as well as those prior art products marketed for carbon removal, to the induction system of vehicles to maximize the effectiveness of the chemical delivery.

Provided is a substrate treating apparatus for treating a substrate. The substrate treating apparatus includes a substrate treating unit configured to supply a water-insoluble water repellent to the substrate to perform water-repellent treatment to the substrate, a decomposition solution mixing mechanism configured to mix a decomposition solution for decomposing the water repellent to a water repellent-containing liquid that contains the water repellent as a waste liquid generated through the water-repellent treatment of the substrate, and a discharging unit configured to discharge a mixed liquid of the water repellent-containing liquid and the decomposition solution to an outside of the substrate treating apparatus.

A method for inspecting a rotary machine having a flow path through which a fluid flows includes a step of measuring a width of the flow path by a non-contact sensor in a stationary component of the rotary machine at a position facing the flow path; and a step of determining whether or not the measured width of the flow path is less than a predetermined lower limit threshold.

The present disclosure provides a chimney cleaning system. The chimney cleaning system may include a support bracket configured to couple with a chimney pipe. The chimney cleaning system may include a first swivel arm and a second swivel arm. The system may further include a spring that connects to a first swivel arm. The chimney cleaning system may include a gearbox, and a shaft, which may be a horizontal shaft, coupled to the gearbox. The chimney cleaning system may further include a chain having a first end and a second end. The first end connects with the first swivel arm via the spring and the second end connects to the second swivel arm. The actuation of the shaft causes a rotation of the chain about the internal surface of the chimney pipe thereby causing the chain to clean soot, creosote, and other debris from at least a portion of the internal surface of the chimney pipe.

An underdrain system for a media pressure vessel has a set of removable pipe sections located between an external header and the bottom of a vessel. Septa extend upwards from the removable pipe sections into the vessel. The header is attached to the bottoms of the removable pipe sections. Each pipe section, and its associated septum, may be removed individually. To clean the vessel, after media is removed from the vessel the pipe sections are removed sequentially while the header remains otherwise attached to the vessel. While a pipe section is removed, its associated septum is removed so that solids can be removed from the annulus between the septum and the vessel. In this way, media can be cleaned from the annuli without moving the external header or entering the vessel.
