A method for maintaining solids and heavy liquids in fluid suspension within a bulk storage tank includes providing a nozzle and suction assembly mounted to a storage tank sidewall having a horizontally extending discharge pipe and a suction pipe for recirculation of the emulsion of fluids within the storage tank. The discharge pipe and suction pipe can be extended to the tank floor and configured with a bend to extend along the tank sidewall to which is attached a submersible swivel joint fitted with a choked nozzle. The nozzle and suction assembly produce positive and vacuum pressure, respectively, for causing the simultaneous discharge and suction of contained tank fluids to cause recirculation. The nozzle may be adjusted so the direction of flow may follow the angle of the tank floor.

The invention relates to a treatment device for workpieces, having the following: a treatment chamber (1); a shaft (2) which extends through a wall of the treatment chamber (1) into the treatment chamber and which is mounted in a rotatable manner; an electric treatment unit (3) which is secured to the shaft (2); and a power supply arrangement (6) with a first supply line (61), an electric coupling (63, 64), a second supply line (62), and an actuating unit (7). The electric coupling (63, 64) has a first coupling element (63), which is secured to the shaft (2) outside of the treatment chamber (1), and a second coupling element (64). The first supply line (61) connects the electric treatment unit (3) to the first coupling element (63), and the second supply line (62) is connected to the second coupling element (64). The actuating unit (7) is designed to actuate the coupling (63, 64) in order to bring the second coupling element (64) into contact with the first coupling element (63) or release the second coupling element (64) from the first coupling element (63).

A displacement detecting apparatus according to the invention comprises: a mover which moves and positions a positioning object; an imager which images an image including an imaging object which is the positioning object or an object displacing integrally with the positioning object as the positioning object is displaced; and a displacement detector which detects the imaging object from the image imaged by the imager and detects a displacement of the positioning object based on the position of the imaging object detected in the image, wherein the displacement detector obtains a displacement amount of the positioning object with respect to a predetermined reference position from a value obtained by multiplying a distance between the position of the imaging object and the reference position in the image by a coefficient determined according to size of the imaging object in the image.

A method of covering a surface of a building, the method comprising spraying an expandable foam material onto the surface and allowing the foam material to solidify whereby to form a covering of the surface and a robotic vehicle configured to carry out the method.

A nozzle unit 22 is attached to a mounting portion 15 of a coating apparatus 10 through a support portion 21. The nozzle unit 22 can move along an arc-shaped guide portion 29 provided on the support portion 21. The guide portion 29 maintains a tip of a nozzle 31 at a center position of the arc shape and supports the nozzle unit 22 such that the nozzle unit 22 can move along the arc shape.

A car wash spray device can include a fluid inlet to receive a pressurized fluid from a fluid source. The car wash spray device can also include a first spray nozzle, and a first pressure-sensitive valve in fluid communication with the fluid inlet and the first spray nozzle. The first pressure-sensitive valve can be configured to allow flow of the pressurized fluid therethrough at or below a first pressure. The car wash spray device can further include a second spray nozzle, and a second pressure-sensitive valve in fluid communication with the fluid inlet and the second spray nozzle. The second pressure-sensitive valve can be configured to allow flow of the pressurized fluid therethrough at or above a second pressure. Controlling a pressure of the pressurized fluid can facilitate delivery of the pressurized fluid through at least one of the first nozzle and the second nozzle.
