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.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system uses a treatment unit for spraying fluid at agricultural objects. The treatment unit is configured with a treatment head assembly that includes a moveable treatment head with one or more spraying tips. A first and second motor assembly are operated by the treatment unit to control the movement of the treatment head. The first motor assembly includes a first motor rotatable in a first rotational axis. A first linkage assembly is connected to the first motor and the treatment head assembly. The first linkage assembly is rotatable by the first motor. The second linkage assembly is rotatable by the second motor.

A system and method have been shown for the effective implementation of a height and rotational adjustment system for a plurality of spray guns for use in a line striper.

A system for automatically washing and sterilizing a heat exchanger of a system air conditioner is proposed. The system for automatically washing and sterilizing a heat exchanger of a system air conditioner according to an embodiment includes: a washer body including an air compressor, a compressed air tank, a detergent liquid tank, a washing water tank, a washing water tank, a high-pressure pump, a hot air generator, a steam generator, and a hot air generator; a washing module that sprays washing water, etc., supplied from the ground during rotation thereof to a cooling fin by a spray nozzle, thus washing the cooling fin; a waste water collection vinyl cover that collects waste water dropping when the cooling fin is washed; and a controller configured to control the washing module that sprays washing water, etc., to the cooling fin.

An adjustable landscaping marking tool includes a strap having a hook disposed at a strap first end, a hook receiving ring disposed on an adjustable connector at a middle section, and at least one (1) marking device aperture disposed at a strap second end. The device is configured to permit a user to secure the hook about a vertical support structure. A marking means secured within a desired marking device aperture may then be used to circumscribe a mark on the ground surface around the vertical support structure.

Systems and methods for treating a plant in a geographic area are disclosed. In one aspect, an agricultural treatment system can include a vehicle having a body and one or more legs operably connected to the body. The vehicle can also include an engine control unit configured to control motion of the vehicle. The system can include one or more image capture devices including a camera configured to capture images of a ground scene or terrain. The system can include an on-board computing system configured to identify features of the images of the ground scene including a target plant. The system can include a treatment unit configured to target and emit a laser beam on at least a portion of a plant located on the terrain.

An effective implementation is shown for a height adjustment system for one or more spray guns used in a line striper.

A nozzle apparatus may comprise a nozzle body having a nozzle tip with a discharge port for spraying a treatment fluid onto a substrate; a nozzle moving member for moving the nozzle body relative to the substrate; a rotating member for rotating the nozzle body or the nozzle tip so that a treatment fluid is sprayed onto the substrate during rotation; and a control unit configured to control an operation of the nozzle moving member and the rotating member.
