- The altered position of a vessel by current or falling to leeward when hove-to or lying-to in a gale, when but little head-way is made by the action of sails. in artillery, a priming-iron of modern introduction used to clear the vent of ordnance from burning particles after each discharge. also, a term sometimes used for the constant deflection of a rifled projectile. (see deflection.)
- [1] that component of a vessel’s or aircraft’s movement attributable to the influence of wind, current or tide. [2] a vessel’s leeway, expressed in knots. [3] an alternate name for current. [4] the speed of a current expressed in knots at sea, but statute miles/ hour in rivers. [5] to float or be driven along by a current of water or air. [6] a short length of anchor chain laid on deck for working purposes. [7] the distance between two blocks in a tackle.

- The deviation of a borehole from its intended direction or target. compare walk.
- Rock, sand, clay, or material deposited by glaciai ice or water.
- A horizontal underground passage parallel to or along a vein or related structure. 4. to excavate a drift; to drive. 5. a tool used for flattening dents or straightening the inward bulges in casing or other pieces of tubular equipment.
- See: concept drift. d-separation two nodes in a directed graphical model are d-separated if all the paths from a to b through common ancestors pass through known (instantiated) ancestors and all of the paths through descendents are not instantiated. nodes that are not d-separated are d-connected. an equivalent condition is that the disjoint subsets a and b are separated by a third subset c in the moral graph of the smallest sub-graph of graph g containing a b c. see also: graphical model, moral graph.
- An approximately horizontal passageway in underground mining.
- 1) a horizontal tunnel. a drift follows the vein, as distinguished
- A synonym of adit, particularly in coal mining.
- Horizontal, underground passage.

Clinometer, английский
- Hand instrument used by foresters and timber cruisers to measure vertical angles. such angles, when correlated with specific distances, indicate the height of standing trees (12).
- An instrument for measuring vertical angles. climbing form 218 clerestory, 1 clevis hanger clip 1. a portion of a brick cut to length. 2.a special fastener made of light-gauge sheet metal or wire for the attachment of gypsum lath to channel or steel studs. 3. a small device, usually of metal, for holding larger parts in place, either by friction or by mechanical action, as a spring device of metal used to hold glass in a window. clip angle, lug angle a short angle iron that takes a portion of the stress of any member.
- An instrument for measuring the inclination of a vessel’s roll, heel, or list. also, but slightly incorrect, inclinometer.
- A borehole-surveying device consisting of a rubber-stoppered, glass culture tube partially filled with a dilute solution of hydrofluoric acid enclosed in a watertight brass or steel container the upper end of which is equipped with box threads fitting the pin thread of a drill-rod coupling. when attached to the lower end of a line of drill rods and suspended at a point in a borehole for approximately 1 hour, the acid etches the inside of the glass tube, forming what appears to be a line where the upper surface of the acid is in contact with the tube. the inclination of that line is measured and with necessary corrections for capillarity indicates the dip of the borehole at the point where the clinometer was suspended. in addition to the above end or plain type, there is the line clinometer and a special type used with the hall-kowe wedging device.
- A simple device for measuring vertical angles, ground slopes, dips, etc. consists of a hinged bar or sighting tube on which is mounted a circular scale and a pendulum or small spirit level.
- Clinometer rule. 2. an instrument used in plane-table surveying, con sisting of a telescope or sighting device pivoted to swing through a vertical graduated arc atop a vertical stand attached to a steel rule, one edge of which is parallel with the sight line of the telescope. 3. sometimes incorrectly used as a synonym for
- Клинометр
