An arrangement is disclosed for the preferably automatic coating of objects with a coating material, in particular coating powder. The arrangement includes at least one spray device having a spray nozzle via which the coating material is dispensable in a main spraying direction. An extension is further provided, wherein an end region of the extension facing the spray device is preferably detachably connected to an end region of the spray device associated with the extension opposite from the spray nozzle. The arrangement further includes a preferably horizontally extending guide via which the extension with the spray device connected thereto can be longitudinally moved in the direction of extension of the guide relative to the object to be coated. The main spraying direction of the spray nozzle may be implemented so as to deviate from the direction of extension of the guide by a predefined or definable angle.

A collapsible mulch dispenser has a collapsible hopper, a blower assembly, and a motor. The collapsible hopper is a freestanding receptacle that has a collapsible frame, a container, an outlet and a declined surface. The container is a bag that is mounted within the collapsible frame so that mulch can be poured into the container to be dispensed through the outlet. The declined surface is mounted within the container and forms a slope that directs the contents of the container to pass through the outlet. The blower assembly is a system used to deposit the mulch onto a desired surface. Accordingly, the motor and the blower assembly are coupled to the out so that mulch can flow out of the container and through the blower assembly.

A powder layer composite includes a base and a powder layer having a thickness of 100 ?m or less and disposed on the base. An average of a total value of a number of powder aggregates having a long diameter of 500 ?m or greater and a number of pinholes having a long diameter of 500 ?m or greater, in any of a plurality of different regions of 20 mm?20 mm on a surface of the powder layer, is 0.2 pieces/cm.sup.2 or less.

A rotary coating tool includes a rotary tool for coating bores and surfaces using solid-state deposition and consolidation of high velocity powder particles undergoing thermal plastic deformation.

An extendable bag roller for supporting a bag of material during removal of the material from the bag includes a bag support having a curved surface configured to support the bag of material on the curved surface and a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag. The bag support includes a base defining a first portion of the curved surface of the bag support and an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes.

A liquid mixture supplying device is provided for mixing a liquid mixture of a liquid and a powder and supplying the liquid mixture to a spray valve for spraying. The device has a structural design consisting of a containing vessel, a driving device, a dip tube and a scraper. The containing vessel is provided for storing the liquid mixture, and the driving device drives the containing vessel to rotate while a scraper disposed on a side of a dip tube is being used for distributing the liquid mixture. The containing vessel is installed in a tiltable external cavity, and a flow barrier is formed on an inner wall of the containing vessel, and the driving device drives the containing vessel to move by a magnetic force or a transmission shaft, so as to achieve the effect of uniform mixing.

An apparatus for enrobing a product portion can include a polymer spray head arranged to direct a plurality of polymeric fibers in an upward direction and levitate product portions in a polymer enrobing zone above the polymer spray head. Polymeric fibers produced by the polymer spray head can wrap around the product portions levitated in the polymer enrobing zone to create an enrobed product. Side guide structure(s) and/or air knife(s) can be provided adjacent to the polymer enrobing zone to inhibit levitated product portions from falling out of the polymer enrobing zone and/or to guide levitated product portions along a desired path. Exemplary enrobed products include smokeless tobacco products.

Implementations are disclosed herein that relate to a firefighting system. An example provides a firefighting system comprising a conveyance configured to receive and elevate screened soil, a chute configured to receive the screened soil at an entry point, and a nozzle configured to emit the screened soil toward a fire site, the nozzle comprising an augmentation device configured to increase a flow speed of the screened soil.

A reactive hopper assembly for feeding a low pressure cold spray applicator for applying powder coatings is disclosed. A powder feed cartridge provides powder feed to a reaction chamber. An impeller housing is interconnected with the reaction chamber for receiving powder feed from the reaction chamber for metering powder feed received from the reaction chamber. A hopper vessel receives metered powder feed from the impeller housing for providing powder to the low pressure cold spray applicator. The reaction chamber is fluidly connected to a source of a reactive gas for chemically modifying the powder feed for in situ reducing surface oxidation of the powder feed.

A mechanical gravimetric disk dispensing apparatus, which in order to prevent compaction of the powder and maintain the flow thereof constant, has a container equipped with an internal mixer that does not require external motorization since it uses that for the rotation of the dosing disk. The mixer is equipped with scrapers to distribute the powder and make it flow on the disk.
