The screw dislocation is more difficult to visualise, but basically comprises a structure in which a helical path is traced around the linear defect ( dislocation line ) by the atomic planes of atoms in the crystal lattice.

For an edge type, b is perpendicular to the dislocation line, whereas in the cases of the screw type it is parallel.

On modern band and orchestral drums, the drumhead is placed over the opening of the drum, which in turn is held onto the shell by a " counterhoop " ( or " rim "), which is then held by means of a number of tuning screws called " tension rods " which screw into lugs placed evenly around the circumference.

The cutting action of the gimlet is slightly different from an auger, however, as the end of the screw, and so the initial hole it makes, is smaller ; the cutting edges pare away the wood which is moved out by the spiral sides, falling out through the entry hole.

Approximately 65 % of the water in the wet gluten is removed by means of a screw press ; the remainder is sprayed through an atomizer nozzle into a drying chamber, where it remains at an elevated temperature a short time to evaporate the water without denaturing the gluten.

Bidding is unrestricted except for the screw the dealer rule: the number of tricks bid cannot equal the number available.

Screw pumps are a more complicated type of rotary pumps, featuring two or three screws with opposing thread —- that is, one screw turns clockwise, and the other counterclockwise.

The twin screw pump is constructed of two intermeshing screws that force the movement of the pumped fluid.

It is necessary to flip back the horizon mirror shade to be able to see the horizon, and then the fine adjustment screw on the end of the index bar is turned until the bottom curve ( the lower limb ) of the sun just touches the horizon.

A screw conveyor is an Archimedes ' screw contained within a tube and turned by a motor so as to deliver material from one end of the conveyor to the other.

With a chain placed on the central sprocket, the screw is turned until a pin is pushed from the linkage

Rotary screw compressors also use positive-displacement compression by matching two helical screws that, when turned, guide air into a chamber, whose volume is reduced as the screws turn.

This is a variation on the older worm and sector design ; the steering column turns a large screw ( the " worm gear ") which meshes with a sector of a gear, causing it to rotate about its axis as the worm gear is turned ; an arm attached to the axis of the sector moves the Pitman arm, which is connected to the steering linkage and thus steers the wheels.

They were set either by sliding a wedge, or later by twisting the handle, which turned a screw, narrowing or widening the jaws.

The final blow to the accident theory was delivered not by Sir Bernard Spilsbury ( who did give forensic evidence of the remains of the unknown person ), but by an expert on automobiles who studied the remains of the Morris Minor, and found somebody had forcefully turned a nut and screw to allow petrol to flow into the motor ( making a fire all the easier to set ).

Roth turned the screw of fantasy and myth one notch higher than others and ended up with a work far truer to the sport: He knew his target, loved it dearly, and knew as well what exaggerations it could withstand.

After hanging the chain on the towing hook the releasing screw must be turned to the tight position.

When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose ( or when screwed the opposite direction, to loosen ).

When the key is turned its teeth mate with teeth on the chuck, turning an internal screw which in turn moves the threaded jaws in or out along a tapered surface.

In this alluring tour through unsettled emotional territory, Jason Patric ( The Lost Boys ) gives an exceptionally sharp performance as an ex-boxer with one screw loose and another turned down tight.

Similarly an electromagnetic ratchet mechanism can be used with a linear screw actuator so that the drive system lifting a load will lock in position when power to the actuator is turned off.

A screw shaft is attached to the plunger, when the shaft is turned the plunger moves in or out of the sleeve and the value of the capacitor changes.

To do so, the instrument is placed on a perfectly level plane surface and the screw turned until the point just touches ; the exact instant when it does so is defined by a sudden diminution of resistance succeeded by a considerable increase.

There are several variants which improve the accuracy with which lever can be moved, including the " Snail " regulator, in which the lever is sprung against a cam of spiral profile which can be turned, the Micrometer, in which the lever is moved by a worm gear, and the " Swans Neck " or " Reed " regulator in which the position of the lever is adjusted by a fine screw, the lever being held in contact with the screw by a spring in the shape of a curved swans neck.

BNC tools are usually light weight, made with stainless steel, and have screw driver type plastic handle grips for applying rotating torque.

Their shafts are usually double the length of a standard screw driver.

A snap-shackle does not screw, and can be released by hand, but it is usually less strong or more expensive than a regular shackle.

There is usually an aziumuth adjustment screw for each position.

Before this, screw threads were usually made by chipping and filing ( that is, with skilled freehand use of chisels and files ).

The reveal tube is usually held in place by a reveal screw pin ( an adjustable threaded bar ) and protective packing at either end.

Compatible screw heads are usually identifiable by a single raised dot or an " X " to one side of the cross slot.

Installing a black box into the telephones commonly used during the 1960s to early 1980s was usually simple because many were assembled using screw terminals meaning that no soldering was required.

* A metal tube crimped over stranded wire to secure it within a screw terminal usually with electrical insulation protecting any exposed portion of the wire not completely inside the screw terminal post.

Basket presses are composed of a cylinder of wooden slats on top of a fixed plate, with a moveable plate that can be forced downward ( usually by a central ratcheting threaded screw.

The grounding screw is usually painted green.

If treatment is required, it is usually a valgus osteotomy of the femur fixed by an angled blade plate device or even a dynamic hip screw.

Another modern type of pickle press is usually made from plastic, and the necessary pressure is generated by turning a screw and clamping down onto the pickles.

Hand-picked or machine-harvested grapes are usually tipped into a receival bin when they arrive at the winery and conveyed by a screw mechanism to the grape-processing equipment.

The blade is usually made of polyurethane and attaches to the shaft by a screw.

For production machine tools, the shank type is usually one of the following: a standard taper ( such as Morse or Brown & Sharpe ), a straight round shank to be held by a collet, or a straight round shank with a flat for a set screw, to be held by a solid toolholder.

For hand tools, the shank end is usually a square drive, intended for use with the same type of wrench used to turn a tap for the cutting of screw threads.

On the lathe, knurl cutting is usually accomplished using the same automatic-feed mechanisms that are used to cut screw threads ; knurling can be thought of as simply a series of threads cut at extremely coarse pitch and in both the left-hand and right-hand directions.

An auger is a drilling device, or drill bit, that usually includes a rotating helical screw blade called a " flighting " to act as a screw conveyor to remove the drilled out material.

With the two screw style, the ring usually aligns well but does not have the strength of the four screw system.
