| Bazooka | (english) Performs functions of Galvanneal Furnace; set of torches on wheels used to shoot flames onto a strip to further heat it. |
| Beam and Sling | (english) Tackle used in conjunction with a crane for turning over the cope or drag of a mold prior to assembly. |
| Bearing Strength | (english) The maximum bearing load at failure divided by the effective bearing area. In a pinned or riveted joint, the iffective area is calculated as the product of the diameter of the hole and the thickness of the bearing member. |
| Bed-In | (english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings. |
| Bedding | (english) Sinking a pattern down into the sand to the desired position and ramming the sand around it. |
| Bench Work | (english) Work done primarily at a bench with hand tools. Occasionlly suplemented by small power-driven tools. |
| Bend Test | (english) Various tests which is used to ascertain the toughness and ductility of a metal product, in which the material is bent around its axis and/ or around an outside radius. A complete test might specify such a bend to be both with and against the direction of grain. For testing, samples should be edge filed to remove burrs and any edgewise cracks resulting from slitting or shearing. If a vice is to be employed, then you must line the jaws with some soft metal, to permit a flow of the metal in the piece being tested. |
| Bent Axis Pumps | (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. |
| Beryllium Copper | (english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc. |
| Bessemer Process | (english) A process for making steel by blowing air through molten pig iron contained in a refractory lined vessel so that the impurities are thus removed by oxidation. |
