A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.
Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. Low-velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate.
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
8 — High pressure coupling 9 — Projectile 10 — Gun barrel. One particular light-gas gun used by NASA uses a modified 40mm cannon for power. The cannon uses gunpowder to propel a plastic (usually HDPE) piston down the cannon barrel, which is filled with high-pressure hydrogen gas. At the end of the cannon barrel is a conical section ...
