The present invention relates to a double bell cup installed on an end portion of a painting robot to centrifugally spray paint to an object to be painted, the double bell cup comprising: an outer body having a tapered structure that becomes gradually wider from the top to the bottom, wherein the outer body has an inlet passage formed on the top side thereof, a stagnation passage formed therein to communicate with the inlet passage, and a spray passage formed on the bottom side thereof to communicate with the stagnation passage, and paint is introduced through the inlet passage and retained in the stagnation passage; and an inner body having a tapered structure that becomes gradually wider from the top to the bottom.

The present disclosure is directed to a holder. The holder includes a main body, the main body including an interior surface and an exterior surface, a film that extends around at least a portion of the circumference of a first end of the main body and covers an opening of the first end of the main body, and a sheet including a first surface and a second surface, the second surface opposed to the first surface, the first surface operably attached to the seal at at least one point, the sheet configured to extend a distance along an interior of the main body from the first end towards a second end, wherein at least a portion of the first surface of the sheet contacts the interior surface of the main body, and wherein a liquid composition contacts a second surface of the sheet.

Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A gas and a slurry that comprises fluid and ceramic particles are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.

A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.

A modular fluid jet attack system provides a system and method for both the containment of spreading flames and extinguishing a fire. A fluid jet system delivers high pressure fluids and abrasive materials to cut a hole in a wall. After the hole is cut, a firefighter can selectively stop the flow of abrasive material to provide fluid only for fire suppression using small droplets on the order of 150 microns. The fluid jet system can employ a gas system to tactically deliver a gaseous agent to aid in a military or law enforcement operation, or to deliver a gaseous agent for use in a firefighting operation, such as an electrical fire. Portions of the fluid jet system, the gas system and the attack system can be mounted in or on a vehicle, trolley, or case for portability.

A high-pressure liquid jet cutting system can include a hopper configured to contain an abrasive mixture that includes abrasive and an additive, and a cutting head configured to receive the abrasive mixture from the hopper and introduce the abrasive mixture into a high-pressure liquid jet. The system can further include a sensor configured to detect a characteristic of the abrasive mixture associated with the additive, and one or more processors operably connected to the sensor and configured to determine information about the abrasive based, at least in part, on the detected characteristic. The one or more processors can be configured to adjust or otherwise control operation of one or more components of the high-pressure liquid jet cutting system based, at least in part, on the information to, e.g., improve or optimize system performance.
