Wedge, английский
- Клин - конфигурация разворота, по виду напоминающая клин;
- Клин, поглощающий клин
- A pie-shaped wooden block hammered in to tighten a batten against its coaming so as to batten down the hatches.
- The act or process of changing the course of a borehole by a deflecting wedge.
- The tapered wedge used to initiate the deflection of a borehole. see deflecting wedge, hall-rowe wedge.
- Tapered pieces of core that tend to bind and block a core barrel.
- Клин ~ of failure призма скольжения, призма обрушения ~ of infinite extent бесконечный клин
- A chart pattern composed of two converging lines connecting peaks and troughs. in the case of falling wedges, the pattern indicates temporary interruptions of upward price rallies. in the case of rising wedges, indicates interruptions of a falling price trend.
- Device used to direct ultrasonic energy into a test object at an acute angle. see also shoe.
- Device used to direct ultrasonic energy into a test object at an acute angle.7,22 see also shoe.
Wedge (ut), английский
A device used to direct ultrasonic energy into a test part at an angle; also, see shoe.
Wedge - shaped brick lintel, английский
Wedge anchor, английский
In prestressed concrete, a device for providing the means of anchoring a tendon by wedging.
Wedge bit, английский
A tapered-nose noncoring bit, used to ream out the borehole alongside the steel deflecting wedge in hole-deflection operations. also called bull-nose bit, wedge reaming bit, wedging bit.
Wedge capping, английский
Wedge clinometer, английский
An end clinometer the bottom end of which is shaped to match the wedge-guide pin on the drive wedge; hence the two can be fastened together with copper shear rivets. when the drive wedge is driven into the wooden plug in the borehole, the copper rivets break, and after the clinometer has been removed from the borehole the relation of the bearing and inclination readings to the flat face of the projection on the bottom of the clinometer ease can be used to orient and place the deflection wedge in a manner so as to direct the deflected hole to follow the desired course.
Wedge combustion chamber, английский
Tapering combustion chamber of overhead valve engine of a type intended to reduce the tendency to detonate. (figure w.3). cylinder bore figure w.3 wedge combustion chamber with roesch
Wedge coping, английский
Coping that slopes in only one direction (not ridged or gabled).
Wedge core lifter, английский
A core-gripping device consisting of a series of three or more serrated-face, tapered wedges contained in slotted and tapered recesses cut into the inner surface of a lifter case or sleeve. the case is threaded to the inner tube of a core barrel. as the core enters the inner tube, it lifts the wedges up along the case taper. when the barrel is raised, the wedges are pulled tight, gripping the core.
Wedge cut, английский
Wedge expander, английский
Brake expander unit in a drum brake in which a taper wedge forces apart two pistons or tappets, which bear on the brake shoes.
Wedge failure, английский
Two intersecting discontinuities release a wedge-shaped rock mass.
Wedge filter (rt), английский
A filter so constructed that its thickness varies continuously or in steps from one edge to the other. wedge filters may be used to increase the uniformity of radiation in certain types of exposures.
Wedge gate valve, английский
Wedge grips, английский
Клиновый захват (испытательной машины)
Wedge guide, английский
Wedge hopper, английский
Wedge hopper:, английский
A hopper in which the sloping sides converge only in one plane (with vertical ends) intended to produce plane flow in the stored solids
Wedge lock, английский
Sliding wedge of a fifth

Gamma-ray source, английский
Skip distance, английский
- In angle beam tests of plate or pipe, the distance from the sound entry point to the exit point on the same surface after reflection from the back surface. also called v path. snell!s law: physical law that defines the relationship between the angle of incidence and the angles of reflection and refraction. source, acoustic emission: (1) unique mechanism that generates acoustic emission. (1) place of an acoustic emission event.
- In angle beam tests of plate or pipe, the distance from the sound entry point to the exit point on the same surface after reflection from the back surface.7 also called v path.22 snell’s law: physical law that defines the relationship between the angle of incidence and the angle of refraction. snr: see signal-to-noise ratio. snt-tc-1a: see recommended practice no. snt-tc-1a.
