More sophisticated systems are able to remove charges from cells which have a higher voltage than the others and to bring them to cells which have a lower voltage in the series connection [58], Among the main converter topologies, the bidirectional nondissipative buck-boost converter [59,60] and the flyback converter [61,62] are the most studied. Active systems appear to be sophisticated circuits and thus may be expensive in relation to the cost of the cell they are intended to protect. [Pg.443]

Steps 5 to 7 are the same as steps 1 to 3 in the opposite direction The permeation mechanism can be simplified by considering only the series connection of three main steps (i) the surface resistance on the upstream side of the membrane due to the surface dissodation of molecular hydrogen and leading to the formation of sub-surface H ad-atoms (ii) the bulk impedance associated with the transport of hydrogen ad-atoms and (iii) the surface resistance on the downstream side of the membrane due to the surface recombination of hydrogen ad-atoms into molecular hydrogen and subsequent transport of gas away from the interface. [Pg.700]

The conclusion is that the GC theory is not satisfactory, mainly due to the assumption of the ions being point charges. It was Stem (1924) who clearly recognized this fact and proposed a modification to overcome that limitation. The modified model is depicted in Figure 3.11 an additional plane, the Helmholtz plane. Stem plane, or 2 plane is defined, as the distance of closest approach to the surface. Ions cannot get closer to the surface, and the space between the plane and the surface, termed the inner layer, is hlled by solvent, which behaves as a dielectric. This model is interpreted, from an electrical point of view, as two capacitors in series one is the inner layer or Stern capacitance, C , and the other is the diffuse layer capacitance, Q. The series connection means that the inverse of the capacitance is additive ... [Pg.44]

The disk filter is similar to the dmm in operation, but filtration is conducted using a series of large diameter filter disks that carry the filter medium on both sides of the disk. They are connected to the main horizontal shaft and partly immersed in the feed slurry. The central shaft is connected by a set of valves which serve to provide vacuum and air as in dmm filters. As the disk sections submerge during rotation, vacuum is appHed to form a cake on both sides of the disk. The cycle of operation is similar to that in a dmm filter. One unit can have as many as 12 disks of up to 5-m diameter. Disk filters, both compact and cost effective, are used extensively in the iron ore industry to dewater magnetite concentrates. [Pg.414]

We will notice subsequently that series and shunt compensation are complementary. What a shunt capacitor cannot do, a series capacitor does and vice versa. On a secondary transmission system, say up to 66 kV, a shunt compensation may always be necessary to improve the power factor, as the load would mainly be indtictive. A series compensation may become essential, to improve the stability of the system, to cope with load fluctuations, switching of non-linear loads and voltage fluctuations occurring on the other power system or the grid to which this system may be connected. [Pg.783]

The piping around any facility, other than the straight pipe connecting the equipment, is made up primarily of a series of control stations. Flow from one vessel goes through a control station and into a piece of pipe that goe.s to another vessel. In addition to considering the use of block valves, check valves, etc., all control stations should be designed so that the control valve can be removed and any bypass valve is located above or on a level with the main control valve. If the bypass is below the con tiol valve, it provides a dead space for water accumulation and corrosion. [Pg.466]

A number of trends connected with ionic radii are noticeable across the series. In keeping with Fajans rules, salts become somewhat less ionic as the Ln " radius decreases reduced ionic character in the hydroxide implies a reduction in basic properties and, at the end of the series, Yb(OH)3 and Lu(OH)3, though undoubtedly mainly basic, can with difficulty be made to dissolve in hot cone NaOH. Paralleling this change, the [Ln(H20)j ] + ions are subject to an increasing tendency to hydrolyse, and hydrolysis can only be prevented by use of increasingly acidic solutions. [Pg.1236]

Capacitor Motor. A capacitor motor is a single-phase induction motor with a main winding arranged for a direct connection to a source of power and an auxiliary winding connected in series with a capacitor. There are three types of capacitor motors, as follows ... [Pg.404]

This series covers recent advances in electrocatalysis and electrochemistry and depicts prospects for their contribution into the present and future of the industrial world. It illustrates the transition of electrochemical sciences from a solid chapter of physical electrochemistry (covering mainly electron transfer reactions, concepts of electrode potentials and stmcture of the electrical double layer) to the field in which electrochemical reactivity is shown as a unique chapter of heterogeneous catalysis, is supported by high-level theory, connects to other areas of science, and includes focus on electrode surface structure, reaction environment, and interfacial spectroscopy. [Pg.704]

Not only is the choice of a uniform prior-prejudice distribution not sensible it also exposes the calculation to two main sources of computational errors, both connected with the functional form of the MaxEnt distribution of scatterers, and with its numerical evaluation namely series termination ripples and aliasing errors in the numerical sampling of the exponential modulation of mix). The next two paragraphs will illustrate these issues in some detail. [Pg.19]

However, more quantitative molecular orbital treatments still leave scope for improvement, and in particular a systematic treatment of the whole metallocene series, rather than of isolated members such as ferrocene, is much to be desired. Moreover, theoretical studies have generally neglected the bis-arene and mixed sandwich series, and in both cases such treatments would be of value in indicating the extent to which the mainly metal n level is or is not less anti-bonding than in the metallocenes. In this connection it is interesting to note that in the (Ch) Cr(Cp)- anion the mainly metal n dxz, dyz ) level may still lie relatively high since esr measurements 1 78) indicate the odd electron to... [Pg.154]

Hydrogen production from wind energy has not been implemented in large-scale WFs yet. The main reason for this, apart from the high cost, is that the present commercially available electrolyzers are designed to operate at lower capacities. An increase in the size of an electrolyzer is achieved by connecting electrolysis stacks in series. [Pg.176]
