Tube reducing

The bonding of the HT cable to the tube reduces production costs and tube length. 

A Pyrex micro filter (Fig. XII, 2, 18) of 8 ml. capacity and furnished with a sintered glass disc is useful for the filtration of hot or boihng hquids. The long cylindrical tube reduces evaporation. The filter may be inserted into a test-tube with side arm (Fig. XII, 2, 13) and the filtrate collected in a centrifuge tube or semimicro test-tube receiver.

Most investigators used tubes open only at the end opposite the point of ignition. For tubes with very large aspect ratios (length/diameter), the positive feedback mechanism resulted in a transition to detonation for many fuels, even when the tubes were unobstructed. Introduction of obstacles into tubes reduced considerably the distance required for transition to detonation. 

The efficiency of the condenser is reduced by poor removal of air and other noncondensable gases because these gases will blanket the tubes, reducing heat transfer and perhaps eventually destroying the vacuum. 

Should it be necessary, before crystallisation takes place, to filter the hot or boiling solutions to remove dust, fibre, etc., the Pyrex micro filter (8 ml capacity) shown in Fig. 2.84 is suitable since the long cylindrical tube reduces evaporation. The filter would be used in an assembly similar to that shown in Fig. 2.82. 

Filters. Metal filters placed near the exit window of the x-ray tube reduce the low energy x-rays emitted at the anode. Their use will reduce the contrast but will improve the resolution. 

If a much larger area heat exchanger is used, considerable improvement is possible. For example, if the 25,600 m heat exchanger has its tubes reduced in radius and coiled, perhaps 100 times more area could result. Using the 0.65 ran thick TH Cr-1 Mo, and cold trapped NaK on the secondary side results in a primary tritium pressure of 0.12 mPa or 8.7 x 10 Torr (29 wppm or 23 kg in a 1630 m liquid lithium blanket).

An open limb U-tube, 85 cm high, made from tubing about 10 mm bore and having a short 1 mm bore constriction in or near the bend, can be used for approximate measurements of pressure within the range 1500 mm to 20 mm Hg. The constriction in the tube reduces surging of the manometric liquid, usually mercury, when the pressure changes and damps out oscillation of the liquid column. 

The layer, formed by the deposits created in the heat exch ger tubes, reduces the heat transfer coefficient leading to ineffective cooling of the gas/vapor products, prolonging their residence time at higher temperatures and consequently reducing the product yield. 

The way in which the intersections lie with respect to the variations of N is also instructive. If a design with N = 1 operating at point D is acceptable and if fouling of the cooling tubes reduces the heat transfer coefficient, there will come a point before N reaches 0.5 when the intersection will slip down to the lower part of the curve. That the designer should be aware of this possibility is of the first importance. The diagram also shows what remedial action to take. If we want the intersection to stay on the upper part of the curve as N decreases, the feed temperature must be increased to ensure that there is a suitable intersection. Even so it is clear that AT at the point of intersection will fall and with it so will the conversion.

AA is the difference in wavelength between two spectral lines of equal intensity. Two peaks are considered resolved if the distance between them is such that the maximum of one falls on the first minimum of the other. Atomic emission apparatus have resolving powers in the order of 30 000 rising to 100 000. The use of a too wide exit slit (bandwidth arriving on the photo-multiplier tube) reduces the resolving power of the spectrometer. 

The apparatus for the preparation of unstable metal hydrides such as FeTiH is shown in Figs. 1 and 2. It consists of a reactor and a pressure-vacuum manifold which is rated for pressures up to 68 atm and is constructed of stainless steel (300 series). The reactor is constructed of j" tubing welded to a metal plug which forms the bottom closure. The top of the tube is welded to a O-ring connector (VCO Type, Cajon Co. 32550, Old South Rd., Cleveland, OH) which in turn is socket-welded to a X tube reducer. A sintered metal disc ( 5 pm...
