A movable rack assembly for a washer having a generally rectangular frame. The frame includes a central hub connectable to a fluid source. A plurality of elongated tubular base members extends from the central hub and defines a bottom of the frame. A pair of spaced-apart elongated, tubular side members defines side portions of the frame and a space therebetween. Each of a plurality of spaced-apart transverse members has ends that are connected to one of the side members. The transverse members transverse the space defined between the side members. A rotary spray arm is attached to each of the transverse members. A plurality of corner spray nozzles on the frame directs fluid toward corners of the frame. The bottom members, the side members and the transverse members are fluidly connected with each other and fluidly connect the rotary spray arms and the corner spray nozzles with the central hub.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

A product applicator system for distributing a liquid product accurately using low volume applications which minimize the quantity of product used and ensures more accurate results. The product applicator system generally includes a housing which includes a removable inlet port mount and outlet port mount. The positioning of the inlet and outlet port mounts on the housing is interchangeable. Supply hoses provide a product to the inlet port mount where the product is traversed through internal conduits to exit the housing via oscillating and overlapping spray heads. An internal motor provides oscillating motion to the spray heads. A rotator assembly which includes a rotator motor may be utilized to orient the housing in horizontal, vertical, or various diagonal orientations. The housing is adapted to either connect to a vehicle, be positioned on a stationary or movable platform, or be connected to a boom using boom connectors.

A drone for cleaning an outer wall of a high-rise building is configured to float and move in the air. The drone includes a drone main body and a floating transfer unit for floating and moving the drone main body in the art. The drone main body has a camera unit provided to photograph the exterior of a building and driving wheels on one surface thereof to be guide to the exterior of the building. The drone main body further has a buffer angle member to cushion an impact with the building and a washing nozzle unit which sprays water onto and washes the exterior of the building. Accordingly, by cleaning the exterior or a window of a skyscraper using the drone, there are the effects of reducing the costs of cleaning a skyscraper, simplifying a cleaning operation, preventing human accidents due to falls, and reducing cleaning time.

A sensor assembly includes a first sensor window defining a first plane, a second sensor window fixed relative to the first sensor window and defining a second plane different than the first plane, and a nozzle positioned to deliver fluid to the first and second sensor windows. The nozzle is translatable along a first axis, rotatable about the first axis, and rotatable about a second axis transverse to the first axis.

An improved cleaning device for an air conditioning condensing unit having a housing with a sprayer cleaning device therein which includes a rotatably disposed spray nozzle connected to a spray nozzle conduit which operably communicably connects to a hose coupling connection outside the housing, wherein the spray nozzle conduit rotates about a rotational axis. A method of cleaning the air conditioning condensing unit employs the sprayer cleaning device.

An apparatus (100) for applying product to the skin of a person in a booth (10), comprising: an applicator (57) configured to apply the product to the person; a first guide (40) configured to guide movement of an applicator in a first dimension, in order to enable the applicator to apply the product to the person at a plurality of different heights; and a second guide (20) configured to guide movement of the applicator in a second dimension, in order to enable the applicator to apply the product across the width of the person. The apparatus may comprise control circuitry for controlling the applicator in dependence upon the weight of the person.

A mold paint-spraying device includes a frame and a mold fixed to the frame. A motor is fixed to the frame, an output end of the motor is fixedly connected to a mounting rack, a servo motor and a linear guide rail are fixedly connected to the mounting rack, a rail slide is arranged on the linear guide rail, a screw nut is fixed on the rail slide, a spray gun is fixed on the screw nut, and an output end of the servo motor is connected with a screw matching the screw nut.

A coating apparatus includes: a nozzle, having a spraying direction; and a rotation part, having a rotation axis, the rotation part being connected with the nozzle to drive the nozzle to rotate around the rotation axis. The spraying direction and an extension direction of the rotation axis are not perpendicular to each other.
