Carlson compass
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
A borehole-surveying device consisting of a gimbal-mounted open frame, rigidly enclosing a graduated circle inside of which is a gimbal-mounted compass. this assemblage, inserted in a glass tube filled with a melted gelatin mixture, is placed inside a tightly sealed brass tube or clinometer. when the tube is lowered into, and suspended at a point in, a borehole for a suflicient length of time to allow the gelatin to set or jell, the position of the gimbal-mounted parts becomes fixed in the solidified gelatin, thereby providing a means whereby the compass course and inclination of the borehole at a specific point may be determined. compare maas compass.

Compasant, английский
A corruption of corpo santo, a ball of electric light observed flickering about the masts, yard-arms, and rigging, during heavy rain, thunder, and lightning.

- Compatible assembly system
- Navigational instrument showing the direction of the vessel in relation to the earth`s geographical poles or magnetic poles. commonly consists of a magnet aligned with the earth`s magnetic field, but other technologies have also been developed, such as the gyrocompass.
- Буссоль, компас
- An instrument for drawing circles, measuring the distance between two points, etc.; consists of two pointed legs, movable on a joint or pivot, usually made so that one of the points can be detached for the insertion of a pen, extension, etc.
- Компас
- The magnetic instrument which indicates the direction in which the boat is headed. coin pass rose. the circles on a chart which indicate the direction of true and magnetic north.
- An instrument employed by navigators to guide the ship`s course at sea. it consists of a circular box, containing a fly or paper card, which represents the horizon, and is suspended by two concentric rings called gimbals. the fly is divided into thirty-two equal parts, by lines drawn from the centre to the circumference, called points or rhumbs; the interval between the points is subdivided into 360 degrees—consequently, the distance or angle comprehended between any two rhumbs is equal to 11 degrees and 15 minutes. the four cardinal points lie opposite to each other; the north and south
- A direction-finding instrument showing the heading of a ship. magnetic compasses orient themselves to the earth’s magnetic field and can only show magnetic north. a gyrocompass depends on the tendency of freely-spinning rotors to maintain spatial orientation, and can be set to indicate true north.
- A maas or other compass device used in borehole-survey work.
- An instrument for determining directions, usually by a device having a magnetic needle free to turn in a horizontal plane.

Compass bowl, английский
A round dish in which the compass card is mounted.
Compass brick, английский
An arch brick. compass-headed arch a semicircular arch.
Compass card, английский
- Картушка компаса
- A circular card, divided around its rim into the cardinal or inter-cardinal points of the compass, or into degrees. a lubber’s line on the fixed compass bowl is aligned to the bow, and hence its intersection with the card shows the vessel’s heading. to a shipboard observer the card seems to rotate when the vessel turns, but in fact it remains aligned to the north while the ship turns around it. also compass rose. almost without exception, the northward direction on a compass card is indicated by a fleur-de-lys—a stylized lily flower, formerly the emblem of french royalty. few mariners would be able to explain why, but the practice dates back to the twelfth century when the french called their water compasses “mariniere.” in 1258, the florentine brunetto latini wrote; “even as our august king is our guide on the land, so does the fleur-de-lys on the mariniere guide the seafarer by constantly pointing to boreas (the ancient greek god of the north wind) no matter how the ship may go.”
Compass center pin, английский
Compass compensation, английский
Adjustments to a magnetic compass to counteract the effects of degaussing.
Compass course, английский
- A bearing as indicated by the horizontal angle between the compass needle and the centerline of the aircraft. a compass course is equal to a true course ± variation and deviation; also equal to a magnetic course ± deviation.
- Компасный курс - угол между направлением магнитной стрелки и диаметральной плоскостью судна в направлении движения, измеренный по часовой стрелке
- Компасный курс
- The angle between the direction of compass north and the ship’s fore-and-aft line, measured clockwise from compass north.
- The course as read on a compass. the compass course adds the magnetic deviation and the magnetic variation to the true course.
Compass deflection, английский
- The difference, expressed in degrees, between the direction a magnetic compass needle points and true or astronomical north.
- Differences, expressed in degrees, between magnetic-north directions and the direction a magnetic compass points, owing to local magnetic interference.

Compass error, английский
Consists of two components. [1] variation, which is caused by the difference between the geographic and magnetic poles, and changes with the observer’s position on the earth’s surface; and [2] deviation, which is due to the magnetic effect of the iron in the ship itself.

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
