Bandsaw

(english) A power saw, the blade of which is a continuous,narrow,steel band having teeth on one edge and passing over two large pulley wheels.

Zirconia

(english) ZrO2 an acid refractory up to 2500 B0C (4532 B0F) having good thermal shock resistance and low electrical resistively.

In situ treatment

(Environmental Engineering) Treatment of a waste in place, as opposed to pumping or digging the waste up and then treating it.

Burnt Rubber

(english) Small or large black spots that generally show up on surface and are generally caused by pickling steel too hot.

Base Type

(english) Tin Mill term; Thickness divided by .00011. Also weight in pounds of one Base Box of Tin plate. In finished inventory base weight is specified instead of decimal thickness.

Fermentation

(Environmental Engineering) Energy production without the benefit of oxygen as a terminal electron acceptor, i.e. oxidation in which the net effect is one organic compound oxidizing another. See respiration.

Bust Coil

(english) Coils removed from the off-gauge reel. The BUST (build up side trimmer) coil contains defects (gauge variation and quality defects) and off-spec widths.

Connection:

(english) Connection is similar to the concept of support, except that connection refers to a relationship between members in a structural model. A connection restrains degrees of freedom of one member with respect to another. For each restrained degree of freedom, there is a corresponding force transferred from one member to the other; forces associated with unrestrained degrees of freedom are zero. See fixed connection and pin connection.

Cement Gel

(Concrete Engineering) The colloidal gel (glue like) material that makes up the major portion of the porous mass of which hydrated cement paste is composed.

Builtup Plate

(english) "A pattern plate of suitable material, with the cope pattern mounted on or attached to one side; the drag pattern may be attached to the other side or to a separate mounting. See Matchplate "

Fixed connection:

(english) In two dimensions, a fixed connection between two members restrains all three degrees of freedom of the connected member with respect to one another. A fixed connection is sometimes called a rigid connection or moment-resisting connection.

Absolute Volume

(Concrete Engineering) The volume of an ingredient in its solid state, without voids between individual pieces or particles, in the case of fluids, the cubic content occupied. In concrete, the actual volume occupied by the different ingredients determined by dividing the weight of each ingredient pounds, by ifs specific gravity, times the weight of one cubic foot of water in pounds. Example: Absolute Volume of one sack of cement equals: 94 ๗ (3.15X62.4) = 0.478 cubic feet
