Applied to plate

The geometry of the cylinder is a matter of convenience. Except for numerical coefficients, the results we shall obtain will apply to plates of any cross-sectional shape. 

Very fine particles such as smokes can be caught by electrostatic precipitation. A high voltage is applied to plates or wires within the filter bank, to impart a static charge to dirt particles. These will then be attracted to earthed plates, and adhere to them. Impurities are generally cleaned off the plates by removing the stack and washing. 

Fig 4 is a diagram of an electron impact 1 source. The sample vapor is admitted into the ion source thru the slit in the back of the chamber and it passes thru a collimated electron beam b . On impact of electrons with the neutral molecules, positive ions (to a small extent negative ions) are produced. A small positive potential ( repeller potential ) between the back wall V of the ion source and first accelerator plate d , expels tile positive ions toward the accelerating region and at the same time attracts the negative ions which are then discharged at repeller plate c . The positive ions are accelerated by the potential difference applied to plates d and e , pass thru the exit slit T and continue toward the collector... 

To prevent withdrawal of the ions thus produced by penetration of the main accelerating field, either a small positive bias is applied to plate 6 or alternatively (31) the exit slit from the ionization chamber is covered by a transparent wire mesh. The ions are withdrawn from the ionization chamber by a voltage pulse of proper sign applied either to the repeller plate (plate 3) or to the ion withdrawal plate (plate 6). 

Cady in World War II realized that such a mechanical resonance of a vibrating crystal could be used in frequency control. This discovery had an important influence on radio communications.Alternating electric fields, such as those generated by the radio tubes of the time, were applied to plates of piezoelectric crystals and the expansions and contractions of the plates were caused to react on electrical circuits. If the natural frequency of the mechanical vibration of the quartz plate coincided with the frequency of oscillation of the electric circuit, resonance between the two took place and energy was acquired by the mechanical oscillators. Later. Rochelle salt and barium titanate, which are each both ferroelectric and piezoelectric, were used. ° In ferroelectric crystals, the polarization or dipole moment is reversed or reoriented upon application of an electric field. Ferroelasticity is another property displayed by some crystals in which stress can cause the interconversion between two stable orientational states. These physical properties of crystals are of great use in modern technology. 

Multivitamin syrups and energy drinks are diluted with an appropriate aqueous-alcoholic mixture (80% ethanol), and the resulting solution is applied to plates for the determination of taurine and lysine. 

No mention has been made of the ion motion in the z direction, but obviously, since no force is exerted on the ions parallel to the magnetic field, the ions would be free to drift in this direction, and would quickly be lost. To prevent this from happening, a trapping potential is applied to plates 2 and 4 (Fig. 1), which is positive for positive ions and negative for negative ions. 

Alkyl phenols Phenols coupled as p-nitrophenol azo dyes applied to plate of silica gel impregnated with alkali. Separated azo dyes located as yellow/red colours upon exposure of plate to ammonia vapour. ... 

The quantity Qj is the thermal power applied to plate j and counted positively if that plate receives heat. In a distillation column, Qn will be positive (reboiler) and Qj negative (condenser). 

These assumptions form the basis for developing the bending theory of plates and apply to plates where buckling is not a consideration. 

Aluminum alloys have a systematic numbering system as shown in Table 4.2. The specification number also designates the various product forms. For example, SB 209 applies to plate products, and SB 210 applies to drawn seamless tube poducts. The first digit of the alloy designation number indicates its major alloying element as shown in Table 4.2.
