(english) (1) The metal present in the largest proportion in an alloy; (2) the metal to be brazed, cut or welded; (3) after welding the part of the metal that was not melted during the process.
(Software Engineering) the process model
(english) The tool used to spot (or position) the rail cars for unloading. It is located on the north end of the unloading area.
(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.
(english) Sinking a pattern down into the sand to the desired position and ramming the sand around it.
(english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace.
(english) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.
(Concrete Engineering) In the manufacture of concrete products, the period between completion of casting and the introduction of additional heat or the steam curing period
(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.
(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.
(Concrete Engineering) In prestress concrete, the device used to stress the tendons.
(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.
