A mechanical tube cleaning system is a cleaning body that is moved through the tube in order to remove deposits from the tube wall. In the most simple case it is a matter of a brush that is moved in the tube by means of a rod or a flexible spring (device). In large-scale technology and industrial sector, however, several processes have ...
Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids.
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be emptied.
On 20 January 1937, the Lamson Engineering Company Ltd was incorporated as a merger of the Lamson Store Service Co Ltd and Lamson Pneumatic Tube Co Ltd. In 1973, the firm was promoting its "Rallypost" system with PVC track and battery-operated carriers that could carry up to 6 kg. [ 4 ]
An air line is a tube, or hose, that contains and carries a compressed air supply. In industrial usage, this may be used to inflate car or bicycle tyres or power tools worked by compressed air, for breathing apparatus in hazardous environments and to operate many other pneumatic systems. [1]
A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work. In the normal sense of the term, the circuit must include a compressor or compressor-fed tank.
Drilling a blast hole with a pneumatic drill (jackhammer). A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2) stored in small cylinders allowing for portability. [1]
Compute the change in the free energy (surface energy − elastic energy) as a function of the crack length. Failure occurs when the free energy attains a peak value at a critical crack length, beyond which the free energy decreases as the crack length increases, i.e. by causing fracture. Using this procedure, Griffith found that
