Engineering steel chain drives are especially suited for heavy-duty apphcations.The normally offset sidebar chain (Fig. 5.87) can handle speeds up to 1000 ft/min (305 m/min) and power... 

To the industrialist faced with a production-limiting foaming problem defoaming cyclones can be a very attractive solution. Any process-related downside risks with these devices are normally deemed minor. When it comes to selling their use to management, their relatively low cost and potential to solve the foaming problem will normally offset any process risk concerns. They may... 

A considerable reduction in stress concentration could be achieved by using a cross-bore which is eUiptical in cross-section, provided the major axis of the eUipse is normal to the axis of the main cylinder. A more practical method of achieving the same effect is to have an offset radial hole whose axis is parallel to a radius but not coincident with it (97,98). Whenever possible the sharp edges at the intersection of the main bore with the cross bore are removed and smooth rounded corners produced so as to reduce the stress raising effects. 

The yield surface in strain space is a ciruclar cylinder normal to the 11 plane with radius k/2fi and axis offset from the origin by e ", as shown in Fig. 5.7(b). It may be seen that, if the yield function in stress space is independent of pressure, then the yield function in strain space is independent of volume change and vice versa. 

As long as the normalization condition given by Eq. (5) is satisfied, an arbitrary offset constant may be added to W(X) without affecting averages in Eq. (3). The absolute value of the PMF is thus unimportant. For convenience, it is possible to choose the value of the free energy W(X) relative to a reference system from which the solute-solvent interactions are absent. The free energy W(X) may thus be expressed as... 

The flexible element coupling requires no lubrication, which is a distinct advantage. The need for lubrication is always a problem with gear couplings. This advantage is partially offset in the flexible element by the need for corrosion-resistant materials for the normal chemical plant atmosphere. Inconel 718 and 15-5 PH have been used and have been rea-... 

Modern hot-wire anemometers are normally used in the constant temperature (CT) mode, where the wire resistance and w ire temperature are kept virtually constant. In the CT-mode the wire is one part of a Wheatstone bridge circuit, which has a feedback from the bridge offset voltage to the top of the bridge (see Fig. 12.18). 

Typical marine propellers are fixed pitch and small in diameter with veiy thin, but broad, blade sections. They are made from either cast metal, corrosion-resistant metal alloys such as copper, or composite materials. Marine propellers normally operate at 60 percent efficiency due to the proximity of the ship s hull, which limits the overall diameter of the propeller and disturbs the efficient flow of water through the blades. As a result, the blades have to be veiy wide to produce adequate thrust. Marine propeller designers use innovations such as overlapping blades and wheel vanes to offset those problems and improve efficiency. 

Oil whirl In an abnormal mode of operation, the rotating shaft may not hold the centerline of the sleeve bearing. When this happens, an instability called oil whirl occurs. Oil whirl is an imbalance in the hydraulic forces within a sleeve bearing. Under normal operation, the hydraulic forces such as velocity and pressure are balanced. If the rotating shaft is offset from the true centerline of the bearing, instability occurs.
