A projectile launching apparatus for cleaning the inner surface of a tube by forcing a projectile through the tube, comprising: a main body containing a breech chamber terminating in an exit port, wherein the breech chamber is provided with a loading port in a side thereof for radially loading a projectile into the breech chamber; a slide disposed on an exterior surface of the main body, the slide being axially movable between a first position wherein the loading port is exposed for loading of a projectile into the breech chamber and a second position wherein the loading port and the breech chamber are sealed; a gas gun operatively connected to the main body in pneumatic communication with the breech chamber; and an exit nozzle connected to the exit port and being connectable to a first end of the tube to be cleaned.

The super nail punch is the only product of its kind that works with not one, but two cylinders, each carefully crafted to serve a specific purpose, and to ensure the nails are installed and secured correctly. This device is uniquely designed to be safe, simple, and highly functional. It includes interchangeable heads that fit the smallest to the largest nails to be employed in the pneumatic accessory, and guarantees the nails are adequately laid and sunk into any working surface. Moreover, the super nail punch is made with durable materials, a triangulated failsafe LED light, and a safety trigger to ensure long term sustainability, when used in private or commercial settings.

A method for determining at least one parameter of a high temperature liquid with a sensor unit and a system to carry out the method. A measuring probe releasably carrying the sensor unit is provided to acceleration means, which accelerates the sensor unit after separation from the measuring probe. The acceleration means is provided in a distance DA to the surface of the high temperature liquid and the distance DA between the surface of the high temperature liquid is less than 50% of the distance of the surface of the high temperature liquid to the opening of the container DM. The sensor unit is projected in the direction of the high temperature liquid, immersed under the surface and the parameter of interest is measured. The invention further relates to a system suitable to carry out the inventive method and a metallurgical vessel comprising the inventive system.
