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
Clinometer case, английский
The watertight brass or steel tube encasing an acid bottle used in determining inclina¬tion of a borehole by an acid-dip survey. see cli¬nometer. also called body, clinometer shell.
Clinometer rule, английский
A simple angle-measuring device consisting of a folding rule, the two arms of which are attached to either side of a graduated hinge member and one arm of which is equipped with a small spirit level. also called angle rule, degree rule.

Plain, английский
- A term used in contradistinction to mountain, though far from implying a level surface, and it may be either elevated or low.
- Простой; ясный; очевидный
- Равнина
- A general term referring to any flat, lowland area, large or small, at a low elevation. specifically, any extensive region of comparatively smooth and level gently undulating land. a plain has few or no prominent hills or valleys but sometimes has considerable slope, and usually occurs at low elevation relative to surrounding areas. where dissected, remnants of a plain can form the local uplands. a plain may be forested or bare of trees and may be formed by deposition or erosion. compare - lowland, plateau. gg

Plain bearing, английский
- A relatively simple and inexpensive bearing typically made of two parts. a rotary plain bearing can be just a shaft running through a hole. a simple linear bearing can be a pair of flat surfaces designed to allow motion.
- Any simple sliding bearing, as distinguished from fixed pad, pivoted pad or rolling bearings. depending on the direction of the load on the bearing surface, plain bearings are classified as guide bearings, journal bearings or thrust bearings.

A churn drill used to drill shallow holes. the drill stem is rigidly connected (by rods or coupled poles) to the reciprocating beam.
Pipe-shoe bit, английский
A bit similar to a pipe bit, except that the set inside diameter is larger. generally, it is used in a one-shot attempt to drill pipe through overburden into bedrock. a pipe-shoe bit is recovered only when the drivepipe is pulled out of the completed borehole.
