Power injection

NOTE Where the fuel tank contains oily water emulsions, sludge, and particulates, the effectiveness of any fuel treatment is directly related to the ability of the additive to penetrate and attack the sludge or emulsion mass. Simply feeding the treatment to the tank does not work. Typically, some form of power-injection equipment is employed to inject the chemical under 100 to 200 psig pressure. Agitation of the entire tank contents also is required and can often be carried out using the same equipment. 

The test commences with a heat extraction of about 1 kW (duration 45 h), subsequently this extraction rate was increased to 1.35 kW. After a total time of 60 h, a short recovery period (10 h) was allowed. During this period the heat pump was reversed and started storing heat in the buffer tank. Subsequently a heat injection of about 1 kW was started, after which there is a transient power injection with a maximum power injection rate of about 3.4 kW. The experiment settings have to be adjusted manually, therefore some control problems are obvious in the graph. For instance, when changing to... 

In parallel to these developments, the capability (modularity) of PROHYTEC to test HTSE at a higher thermal power has to be assessed in an objective of performance testing by 2015. Typically, calculations have shown that the electrical power which could be injected in the HTSE is about 2.5 MW when the exchange thermal power at the steam generator level is about 0.8 MW. When the available power will be about 7.8 MW the thermal power could be of 1.9 MW and the electrical power injected in the HTSE of about 5.9 MW. This increase in power could match the objective of 2015 but is still to be defined.

FIGURE 11.12 He-like and Li-like argon spectrum using quartz (loT) crystal. HF power injected P = 400 W. Argon partial pressure pAr = 5 x 10 mbar, total pressure ptot = 5 x 10 mbar. This spectrum has been obtained with an integration time of 2 h. The focal position of this spectrum was in correspondence to the ls2p Pn — Is Sq peak, near channel 310.

It seems that the milling intensity (power injected) is the characteristic milling parameter that defines final (steady-state) phase induced by milling, so it has been suggested, that it should be quoted whenever possible in order to compare diverse investigations [73].

Load coming on-line without grid connection. The requested power from the load coming on-line is a step function, while the inertia-less micro source always takes a finite amount of time to ramp up to the newly requested value. Since the unit cannot change its output power instantaneously, the power is balanced by voltage reduction. As the power injected from the micro source increases to supply the needed load the voltage is restored. 

The pancreatic phase of contrast enhancement is performed through the pancreas 40-45 s after a bolus of iodinated contrast is power injected through an antecubital vein at a rate 4 mL/s. For the pancreatic phase of contrast enhancement, the scan is performed from the diaphragm to the iliac crests. This should be performed with the thinnest slice collimator available on the CT scanner, so for a 16 row scanner 16 x 75. 

The reflection coefficient and return loss are, in general, a function of the frequency. A typical design criterion requires that the reflection coefficient satisfies r = 5ii < —10 dB, for fi less than 10% of the power injected at the antenna terminals may be reflected, over the frequency band fL,fH -...

It may be helpful to separately represent the power supplied by the battery (see Figure 3.17) and the power injected into the battery (Figure 3.18), Although this division is artificial (there is no discontinuity between these two currents), it enables us to show the amount of electricity consumed during traction and the amount that is recovered during braking.

The NiCd battery in this Peugeot 106 has a nominal capacity of 12 kWh. The power injected and the SOC are shown in Figure 3.21. 

Typically a groin approach is used and the celiac axis is selected with a Sos catheter. Selective angiography is performed to lay out the splenic artery. A glidewire is then passed distally and either the Sos or a Cobra catheter is advanced. Embolization can be performed through the 5 French catheter at this point. If too tortuous, then a microcatheter can be passed coaxially. (Fig. 8.4) We use either a Mass Transit (Cordis, Miami, FL) or Renegade (Boston Scientific, Boston, MA) microcatheter. These catheters can withstand a power injection of 2-3 cc per second if needed.

A safe IV line is always necessary, and our preference goes to an antecubital catheter. The largest possible size is chosen. Placement of the catheter is ideally performed by a nurse in the outpatient suite after skin preparation with anesthetic cream (lidocaine-prilocaine, Emla ). This catheter makes it possible to use a power injector. Power injection provides an excellent examination quality, and continuous flow decreases the risk of extra vascular passage. The injection should be visually monitored and stopped in case of extra-vascular passage. In younger children, hand injection under visual control seems safer.
