An interactive toy system is shown and described. The toy system can include a container forming a receptacle and having a top opening and a carriage. The carriage is disposed in the receptacle and rotatable about an axis between a first position and a second position. The carriage has a first receiving space and a second receiving space. The first receiving space is accessible through the top opening when the carriage is in the first position and inaccessible when the carriage is in the second position. The second receiving space is accessible through the top opening when the carriage is in the second position and inaccessible when the carriage is in the first position. The toy system can include a fog system configured to generate fog within the container. The fog obfuscating the first receiving space.

A method for plasma coating an object includes an object profile, having the steps of: a) manufacturing a replaceable shield comprising a jet inlet, a nozzle outlet and a sidewall extending from the jet inlet to the nozzle outlet, wherein the nozzle outlet includes an edge essentially congruent to at least part of the object profile; b) detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; c) placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge; d) plasma coating the object with a low-temperature, oxygen-free plasma at an operating pressure which is higher than the atmospheric pressure by providing a plasma jet in the shield via the plasma jet generator and injecting coating precursors in the plasma jet in the shield.

This invention relates to a method, system and apparatus for cladding a surface of an articles subject to corrosive, erosive or abrasive wear, such as impact or grinding tools. The method includes providing a supply of stock material and feeding the stock material towards a portion of the surface of the article via a dedicated feed source. A dedicated heat source heats the fed stock material and the portion of the surface of the article such that the heated stock material and the portion of the surface at least partially melt. Upon removal of the heat, the molten feedstock and the surface portion form a bonded coating layer on at least a portion of the surface of the article, thereby protecting that part of the assembly against wear.

A cooling system for a cold spray nozzle or a thermal spray barrel and a fabrication method thereof are provided. The cooling system includes a sleeve with cooling fins that encapsulate a spray nozzle or barrel to enable heat transfer from the nozzle or barrel to the fins and then to the external ambient environment. The sleeve may optionally include one or more channels with cooling tubes to enable enhanced cooling with a cooling medium flowing through the tubes and across the fins.

The present invention provides a plasma torch which comprises: a first pipe having a first flow channel through which a liquid can flow, a first exit through which the liquid is sprayed being provided on an one end side; a second pipe body that surrounds the first pipe body, and has a second flow channel through which a gas can flow, a second exit through which the gas is sprayed being provided on the one end side; and an electrode extending into the second flow channel. The second exit is provided further to the one end side than the first exit, some of the inner peripheral surface of the second pipe decreases in diameter towards the second exit, and the diameter of the inner peripheral surface closer to the second exit than the first exit is equal to or larger than the opening diameter of the first exit.
