A dry to wet abrasive blast machine conversion kit and method usable to convert an existing blast pot configured for sand blasting for use in wet abrasive air blasting includes a multi-function fluid manifold, and a control panel attachable to the blast pot to effectuate a first hydraulic circuit, a second hydraulic circuit, and a pneumatic circuit. The dry to wet abrasive blast machine conversion kit installs to the existing blast pot as is, and therefore enables conversion for wet abrasive blasting without additional penetrations through the blast pot envelope which might otherwise compromise manufacturer warranty and use ratings.

A method for cutting electrode foils and a device for cutting electrode foils that are intended for use in a battery cell are proposed. The cutting device

comprises a cutting tool, a vibration device for exciting at least the cutting tool to vibration, and a particle feed line for feeding at least particles. The cutting tool can be arranged above the electrode foil with a separation from a surface of the electrode foil, and the electrode foil can be cut at least as a result of the vibrations of the cutting tool that are transmitted to at least one particle.

An improved wet abrasive blast machine with remote control rinse cycle enables a pilot operating the apparatus to control remote switching between blast and rinse cycles directly, for example from a nozzle of a blast hose or from a panel. A first and second hydraulic circuit and a pneumatic circuit are controllable via communication with a control circuit which is operable remotely to direct a configurable pilot signal between various valve states. In a preferred embodiment, the control circuit is powered pneumatically via a branch circuit fed from the pneumatic circuit. Switching between to configurations is effected by directing an air pilot signal between airflows interior to a series of valves. In an alternate embodiment switching airflows between configurations is effected electrically.

A hydrodynamically optimized mixer module, to be coupled to a deterministic hydrodynamic tool that allows pulsed polishing of optical surfaces is described. This module allows the supply of abrasive foam or fluid that enters the tool to be interrupted without impairing the operational stability of the polishing process and of said hydrodynamic tool. The mixer module includes at least one interrupter element for switching high-velocity fluids; a first inlet through which air is injected under pressure and in a controlled manner; a second inlet through which a polishing fluid is injected in a controlled manner, said polishing fluid filling a predetermined volume with a hydrodynamically optimized shape and being transferred to a mixing zone where, together with the pressure-injected air, an abrasive foam is produced that is injected into at least one rotational acceleration chamber of the hydrodynamic tool to which the mixer module is coupled.

A blasting system, comprising a tank, a center tube, an inlet, a top aperture. Said tank holds a slurry mixture for blasting application. Said inlet receives a pressurized air. Said center tube receives a portion of said pressurized air and selectively receives a portion of said slurry mixture. A portion of said center tube exits said tank at said top aperture. Said tank comprises a top end and a bottom end. Said relief valve regulates fluid capacity in said tank and relives pressure from said tank.

The invention is directed toward a mobile wet-abrasive blasting system used for cleaning, preparing surfaces, removing coatings, and other abrasive blasting applications. The wet abrasive basting system has a blast pot that includes pilot-controlled pneumatics to control the loading, pressurizing, de-pressurizing, and wash down functions. The wet-abrasive blasting system also uses a floating bung in conjunction with a vent mechanism to further automate the pressurizing steps in setting up the system. The wet-abrasive blasting system also uses pilot-controlled pneumatics to decide the blasting function options of just water, just air, or water/abrasive mix and air. Wet-abrasive blasting systems mix an abrasive media with water and convey the mix to meet compressed air and direct through a blast hose and nozzle.

A wet abrasive blast pot includes a cylindrical pressure vessel have a top section, a bottom section, and sidewalls extending between the top section and the bottom section. The bottom section includes an outlet, and the top section includes a fill inlet. The top section includes a convex head, with the fill inlet located at the uppermost portion of the pressure vessel.

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.

An abrasive blasting system has an abrasive container or pot, preferably with a downwardly conically shaped interior bottom surface. A slurry delivery tube is positioned within the pot, with an open bottom end positioned at an operative distance above the bottom of the pot. The slurry delivery tube runs vertically upward and exits the pot, ultimately running to a hose and nozzle. With an abrasive slurry of solid particulate abrasive media and water inside the pot, air pressure is applied within the pot. When a relatively lower pressure is created in the slurry delivery tube, the resulting pressure differential moves the slurry downward within the pot, then upward through the slurry delivery tube, through the hose and ultimately to the nozzle, where it is directed by an operator onto a workpiece. The system is especially useful when using very fine abrasive material.
