Angle plates

The speed at which a sphere roUs down a cylindrical tube filled with a fluid or down an angled plate covered with a film of the fluid also gives a measure of viscosity. For the cylindrical tube geometry, equation 35, a generalized form of the Stokes equation is used for any given instmment, where p is the translational velocity of the rolling sphere and k is the instmment constant determined by caUbration with standard fluids. 

This angle plate gravity separator removes suspensions of solids from a dilute liquid. The unit is more compact than a box-type settler due to the increased capacity achiev ed by the multiple parallel plates. The concept is fairly standard (U.S. Patent 1,458.805—year 1923) but there are variations in some details. For effective operation, the unit must receive the mixture with definite particles having a settling velocity. The units are not totally effective for flocculants or coagulated masses that may have a tendency to be buoyant.

If aerosolization is a major contributor to a hazard, a portion of the airborne liquid can be removed by placing an angled plate over the release point. The released material strikes the plate, which disperses much of the momentum and enhances coagulation of liquid droplets. In this way a portion of the liquid will drop out of the cloud. However, the loss of momentum may result in less efficient vapor dispersion and, hence, a larger hazard area.

When the workpiece has to be positioned at 90° to the reference surface, it can be clamped to an angle plate (Fig. 3.10). Angle plates are usually made from cast iron and the edges and faces are accurately machined flat, square and parallel. Slots are provided in the faces for easy clamping of the workpiece. Angle plates may be plain or adjustable. 

Clamps are used when the workpiece has to be securely fixed to another piece of equipment, e.g. to the face of an angle plate (Fig. 3.10). 

Clamp the plate to the face of an angle plate, ensuring that the clamps will not interfere with marking out. Use a scriher in a surface gauge and set the heights in conjunction with a precision steel rule. Scribe the datum line. Scribe each horizontal line the correct distance from the datum. 

Without undamping the plate, swing the angle plate on to its side (note the importance of clamp positions at step 1). This ensures that the lines about to be scribed are at right angles to those scribed in step 1, owing to the accuracy of the angle plate. Scribe the datum centre line. Scribe each horizontal line the correct distance from the datum to intersect the vertical lines. 

Surfaces required to be ground at right angles can be clamped to the upright surface of an angle plate.

Scanning the etalon and coarse tuner in tandem, the laser will tune in steps of the cavity FSR, c/21c, where Ic is the cavity length. Typical cavity FSRs are on the order of 300 MHz. Tuning the laser frequency between adjacent cavity modes can be achieved by smoothly increasing the cavity length by X/2. This is usually accomplished with a piezoelectric transducer (PZT)-driven cavity mirror or a tilted Brewster angle plate. To achieve smooth continuous scans, the three tuning elements must be synchronized.

The other type of bolted joint considered here is that used to connect beams to columns, and columns to colunm bases. These joints usually involve additional connection components in the form of angle or flat plate profiles. Consequently, both the bolts and the angles/plates participate in the transfer of bending moments and shear forces between beams and columns and between columns and their bases, and in the latter case also uplift forces. 

Alternative data collection possibilities to the immersion technique are shown in Figure 19. Squirter systems, couplant flow systems, and various contact methods may also be used to employ the normal beam shear wave, critical angle, plate wave, surface wave, back-scattering, or frequency perturbation techniques.

The flow resistance of the mixer can impose excessive stresses on the mixer itself. Following element folding, in an angled plate static mixer where the welded elements proved unable to withstand the loads applied in a melt cooling application, it was replaced by a single piece element machined from a solid steel blank. This proved suitable for the task (Figure 11.5).
