Protection systems schematic diagram

A combined filter and manure system must be completely reliable, since it is not easy to make repairs under the slats. After 2-3 years of experience a system which works well has been developed. (2, 3, 4) In Fig.2 a schematic diagram of the filter system is shown under the slatted floor. In the channel under the slats two angle sections (1) are attached one above the other and fixed over the whole length to both walls. These are covered from above with protective plates (2) joined underneath the slats. The filter net (3) is provided with... 

Figure 7.2 Schematic diagram of the dilution concept , including purging. Time axis t = top to bottom protective gas flow V = left to right, (a) Containment system as a source of release of a flammable substance, protective gas is air. After purging, the protective gas flow is reduced to ensure an adequate dilution of the flammable release down to =s25% LEL. (b) Containment system as a source of release of a flammable substance accompanied by oxygen, protective gas is an inert gas (e.g. nitrogen, N2). After purging, the protective gas flow is reduced to ensure a safe oxygen level s 2% (v/v) 02.

Fig. 9. Schematic diagrams of the major components of cw and pulsed EPR-ENDOR instruments. The sample is in a resonant microwave cavity, situated between poles of a magnet and surrounded by a temperature-control system (not shown). The structure of the circulator directs microwaves from the source to the cavity, and from the cavity to the detection system. A radio frequency synthesizer provides rf to coils situated around the cavity. Note that this diagram shows an arbitrary orientation of the rf coils. For convenience the magnetic field modulation coils are not shown for the cw spectrometer. For the pulsed EPR spectrometer (B), fast switches (ovals) are used to control pulse timing for the rf and microwave pulses, as well as to protect the detector. For simplicity, several features including the timing circuitry are not shown. The signal from the detector is sent to a boxcar integrator. Both spectrometers are computer-interfaced for data collection and storage. Further details may be found elsewhere.

Fig. 7 Schematic diagram of the cyclodextrin-containing delivery system, (a) Components of the delivery system. The CDP condenses siRNA and protects it from degradation. The AD-PEG stabilizes the complexes in systemic circulation via inclusion compound formation. The AD-PEG-transferrin (Tf-PEG-AD) conjugate confers a targeting ligand to the complex, (b) Assembly of the targeted delivery systems. CDP, AD-PEG, and Tf-PEG-AD are combined and added to siRNA to generate stable complex. (Adopted from Cancer Research 2005 65 8984-8992)...

Impressed current cathodic protection requires (i) DC power supply (rectifier) (ii) an inert anode such as catalyzed titanium anode mesh (iii) wiring conduit (iv) an embedded silver/silver chloride reference electrode. A schematic diagram of an impressed current cathodic system is shown in Figure 5.26. By an impressed current, the potential of the steel is adjusted to values greater than -850 mV, thus making the steel bar cathodic and prevent the corrosion (25). 

To protect HEPA filters against premature clogging, air filtration is usually multistage. At least one prefilter is added to remove dust from the air before it enters the HEPA filter. Figure 29.19 shows a schematic diagram of a typical aseptic spray dryer system.

Effective and economic anticorrosion protection of structures is obtained by the simultaneous application of appropriately chosen insulation coatings and cathodic protection. Both types of protection can be applied simultaneously and they can mutually supplement each other (Peabody, 1967). The general schematic diagram of a modern anticorrosion protection system of pipelines is presented in Fig. 8-17.

Figure 1-2 shows the simplified schematic diagram of the SMART nuclear steam supply system (NSSS) and exhibits the safety systems and the primary system as well as auxiliary systems. The engineered safety systems designed to function passively on demand consist of a reactor shutdown system, passive residual heat removal system, emergency core cooling system, safeguard vessel and reactor overpressure protection system.

A.804. The requirements for the reactor protection system are discussed in paras 626-634 of Safety Series No.35-Sl. The reactor protection system, including all its components, shall be described in detail. A schematic diagram shall show how the parameters for initiating protective actions are derived from monitored process variables, such as neutron flux, temperatures and flow, and how these parameters are logically combined. 

Figure 6-20. Schematic Ti-Al phase diagram (after Kattner et al. (1992) and Zhang et al. (1997)). There is no overlap between protective AI2O3 scale formation in air and room-temperature ductility (with alloying additions) in the Ti-Al system. The intermixed AI2O3 + Ti02 scale that forms on titanium aluminides can provide adequate protection from scaling up to ca 750-800 C.

Figure 6-28. Schematic binary Nb-Al phase diagram (after Cervant and Ansara (1997) and Colinet et al. (1997)). There is a wide gap in protective AI2O3 scale formation and room-temperature ductility in the Nb-Al system. (Note that binary NbAb is only capable of AI2O3 scale formation under limited time and temperature conditions.)...
