screen


screen,

in architecture, partition or enclosure not extending to the ceiling; usually a structure in stone, wood, or metal. It frequently serves to mark the boundaries of portions of churches and cathedrals. The choir screen or chancel screen, the most usual form, separates the choir or chancelchancel,
primarily that part of the church close to the altar and used by the officiating clergy. In the early churches it was separated from the nave by a low parapet or open railing (cancellus), its name being thus derived.

 from the body of the church. In many medieval cathedrals the choir screen was a richly decorated structure of pierced stonework, often with sculpture. The screens of the cathedrals of Chartres and Albi in France and of York, Lincoln, and Durham in England are especially noteworthy. Many English parish churches contain fine screens of carved and painted wood. In the basilican churches of Italy, such as St. Mark's, Venice, the chancel front was often marked by an elaborate inlaid marble parapet wall. With the coming of the Renaissance the constructing of chancel screens became rare except in Spain, where rejas of ironwork or bronze were extensively employed (see grillegrille,
in architecture, a system of bars, usually of decorative metalwork, forming an openwork barrier or enclosure. In its usual materials of wrought iron or bronze, it has been favored for decorative treatment in all periods.

). In Greek Christian churches, the choir screen takes the form of a solid partition, the iconostasis, decorated with holy images (whence its name) and usually provided with three doors. It entirely separates the sanctuary from the body of the church and conceals from the congregation the altar and the celebration of Mass. The rood screen is a more elaborate form of choir screen that bears the roodrood

 is a wall or screen behind the high altar. As an article of furniture, the folding screen is of great antiquity, dating in China from the 2d cent. B.C. Widely used to adorn palaces and mansions, the screens of China and Japan were often gorgeous conceptions with carved wood frames, their panels of rich textiles or inlaid with jade and precious metals. The use of the folding screen, often showing East Asian influences in its construction, materials, and design, has continued to the present day.

Screen

Any construction whose essential function is merely to separate, protect, seclude, or conceal, but not to support.

Screen

 

a device or machine for the mechanical sorting of bulk materials according to size of particles (pieces). It is used to divide coal, ore, or crushed stone into fragments, and also to dry materials (enriched coals, washed ores, and so on). The screen is one of the basic types of mechanical equipment of crushing and sorting mills and preparation plants. Fixed screens are classified as devices; mobile screens, as machines.

Fixed screens (bar. arc. and conical screens) consist of the working part of a stationary screening surface and its supporting structure. Bar screens have an inclined surface with slots larger than 50 mm and are used for crude sorting of material that comes in large chunks: arc screens are used to dry and sort fine-grain materials (coal or sand); and conical screens are used for drying and crude sorting.

Mobile screens (machines) assure highly efficient screening. They consist of one or more screening surfaces (sieves), their supporting structure, and the drive mechanism for the sieve. In terms of the type of motion of sieves, a distinction is made among screens with rotating surfaces (trommels), shaking screens, and vibrating and semivibrating types. Trommels consist of concentric screening surfaces that rotate about a single axis. They are used mostly for washing materials and for incidental crude sorting. Shaking screens have one or more sieves that are fastened to a rectangular crib linked to a driving mechanism, usually an eccentric. Material moves along the sieve under the force of gravity or inertia. Thanks to the rigid kinematic link between the crib and the eccentric, the scope of vibrations of the sieve is strictly defined and does not depend on the load in the crib. The crib of a vibrating screen is oscillated (vibrated) by the forces created by a vibrator. According to the kind of vibration, screens of this type are classified as linear, elliptical or circular. Unlike shaking screens, the magnitude of the sieve’s vibrations in vibration screens is not constant but depends on the load.

All types of screens are used in industry, but the most promising are the vibrating type (see Table 1). Within this group special attention is due so-called resonance screens, in which the motor’s energy is expended only to overcome resistances to vibration and not to impart kinetic energy to moving masses. Therefore resonance screens require a less powerful drive, and the balanced state of the material makes it possible to build such screens with large screening surfaces.

Screen

 

(1) A large operations unit consisting of individual detachments in Soviet Russia in the initial period of the Red Army’s formation, when it was extremely small in size. The screen system was established by the Supreme Military Council to defend the demarcation line established after the Treaty of Brest in March 1918. It included the Northern Sector (March 14-September 11), the Southern Sector (August 5-September 11), and the Western Sector (April 8-September 11) of screen detachments. The screen sectors were headed by military councils, each consisting of a military leader and two political commissars. Small headquarters were established to direct the screen detachments. The screen system later served as the basis for deployment of a number of armies and fronts.

(2) A method of camouflage. The screen is created by smoke or by hanging up authorized (or available) means that conceal the particular military objects (structures, positions, and so on) against visual and air observation by the enemy.

(3) Submarine curtain, a group of submarines formed in general search or combat formation for joint performance of the assigned combat mission.


Screen

 

In printing, an optical device used in the reproduction of halftones. Such a device consists of a system of opaque elements—most often, parallel lines—that are applied to a nondeforming base, such as glass. Screens differ in the character of the opaque elements (Figure 1) and in the line frequency, that is, the number of such elements per centimeter. Depending on the technique involved, screens may be classified as projection or contact types. Projection types (Figure 1,a-d) are used only in photographic processes. Such a screen is mounted inside the process camera at a small, precalculated distance from the photosensitive layer. The light flux that passes through the screen during exposure is broken up into separate beams of light; these beams have the same dimensions but differ in intensity,

Figure 1. Screen types: (a) one-way, (b) crossline, (c) Schultze (rhomboid), (d) mezzograph, (e) contact, (f) for intaglio printing

which depends on the brightness of the sections of the original that are being reproduced. The different quantities of light that reach the photosensitive layer cause the formation of exposed sections on the negative in the form of dots or lines of unequal size. The density, structure, and overall dimensions of these dots also depend on the exposure parameters and on the characteristics of the light sources, screen, and photographic material.

Contact screens (Figure 1,e) are used in contact with photosensitive layers. They are employed both in photographic processes and in the transfer of an image from a negative or positive to the printing surface. The formation of the screen image is a result of the absorption of part of the rays coming from the original by the dots on the screen, which are of nonuniform density. There exist gray (silver-containing) and magenta (based on finely dispersed dyes) contact screens. The dyed screens are preferable because of the better quality of the resulting image.

In relief and planographic printing, crossline or autotype screens are generally used. The line frequency in this case ranges from 24 to 60 lines per cm (Figure 1,b). Intaglio printing employs special contact screens with high line frequencies (Figure 1,f). These screens are used in the transfer of the image to the printing plate.

What does it mean when you dream about a screen?

The dreamer may be needing to “screen out” information that she or he may not be able to assimilate.

Screen Stocks

To investigate stocks for potential investment according to a predetermined set of criteria. For example, an investor may screen stocks according to the lowest price, the most market capitalization, the most favorable price-earnings ratio, or any number of other variables. One may also combine criteria while screening stocks. The process is designed to help one make the best investment decisions, and is often accomplished with the help of a computer.

screen

To examine various securities with the goal of selecting a limited number that meet certain predetermined requirements. For example, an investor might screen all electric utilities for stock that offers a dividend yield of 8% or more and a price-earnings ratio of 8 or less.

Screen.

A screen is a set of criteria against which you measure stocks or other investments to find those that meet your criteria.

For example, you might screen for stocks that meet a certain environmentally or socially responsible standard, or for those with current price-to-earnings ratios (P/E) less than the current market average.

A socially responsible mutual fund describes the screens it uses to select investments in its prospectus.
