A glass container that includes a base defining a hole, and methods of manufacturing and using the glass container, is disclosed. The glass container is manufactured by providing the container and cutting a hole in a wall of the container. The hole may be cut into the wall by any technique in which glass material is separated from the wall including by mechanical shearing, thermal energy, and/or fluid impingement. To use the glass container, a deformable blow-out plug may be inserted into the hole to fluidly seal the hole, a liquid beverage may be introduced into the container, a closure may be coupled to the container to close the container and provide a pressurizable package, and thereafter the package may be internally pressurized by introducing a pressurizing gas into the package.

A shutdown system for a media blast system includes a normally closed diverter path which remains closed to air flow during operation of the blast system. During shutdown, the air flow to the metering valve is shut off, shutting off the system. At the same time, the diverter path is opened, relieving pressure in the supply line by permitting pressurized air and abrasive in the supply line to back flow through the diverter from which it is exhausted, almost instantaneously shutting off flow through the nozzle. A diffuser system is included for receiving and exhausting residual abrasive media and for reducing the noise level of the exhausted air.

Provided is a centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet and through the media separator. The centrifuge media separator comprises an upper panel, a lower panel, and an outer wall. The upper panel has a central opening formed therein. The outer wall is configured in a truncated logarithmic shape and which extends between the upper and lower panels. The outer wall has at least one particulate escape aperture formed therein. The upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet. An air foil extends from the outer wall in to the air passageway. The distance than the air foil extends in to the air passageway is adjustable. The inlet is configured to allow a flow of air to enter the air passageway and circulate therethrough toward the outlet. The escape aperture is configured to exhaust the blast particulate out of the passageway. The central opening is configured to exhaust the fine particulate out of the passageway.

A method for treating a surface of a fibre composite component, wherein an abrasive removal of the surface of the fibre composite component takes place by blasting a removing agent transported by a gaseous transporting fluid onto the surface of the fibre composite component by a feed nozzle and a suction extraction of the removing agent and material removed by the removing agent takes place by an extraction nozzle arranged in the region of the feed nozzle.

The present invention relates to a welding jig micro-cleaning apparatus, and more particularly a welding jig micro-cleaning apparatus including a housing, a sandbox connected to the housing, an air supply unit connected to the sandbox through with a hose, a blasting gun positioned in the housing, a jig fixing portion positioned at a lower first end of the blasting gun, and a controller, wherein the jig fixing portion includes a magnetic unit configured to fix a welding jig.

A management device simultaneously clamps both the power cord and the vacuum tube of a floor preparation machine to appropriately direct the power cord and vacuum tube and protect from damage the power cord, vacuum tube cord plug and machine socket associated with the power cord and fitting associated with the vacuum tube.

An apparatus for treating a surface of an object is disclosed, including a carrier configured to transport the object through a treatment zone and an array of nozzle devices, each nozzle device positioned to deliver a cavitating jet into the treatment zone. The apparatus further includes a fluid source, a pump connected to the fluid source, and a hose configured to carry fluid under high pressure generated by the pump from the fluid source to the array of nozzle devices.

A device for irradiating a suspension on workpieces, the device including at least one pressure vessel for the suspension; at least one feed line for the suspension connected to the pressure vessel, the feed line is connected or can be connected to a radiation device; at least one valveswitched between the pressure vessel and the radiation device; at least one prechamber connected to the pressure vessel by a valve; at least one return line for the suspension, connected to the prechamber; and a line and a valve, by which the prechamber can be connected to a compressed air source or by which the prechamber is connected to a compressed air source. The valve between the prechamber and the pressure vessel is a check valve connected at its one upper, connection at a pressure vessel connection, which discharges into the pressure vessel through the bottom of the pressure vessel at the lowest point thereof, and which is connected at its other connection to the prechamber, wherein the flow direction of the check valve is directed toward the pressure vessel.

A polishing method includes: a step of preparing a polishing device including a processing member and a suction mechanism configured to generate suction force; a step of setting a workpiece in the processing member; and a step of accelerating abrasive grains fed toward the workpiece to a predetermined speed with an air flow generated by operation of the suction mechanism, and polishing the workpiece by causing the abrasive grains to contact with or collide with the workpiece.
