Figure 4-3. Absolute values of the INDO/SCI-calculalcd electron wavcfunctions v/(a, jt, = 34) calculated for the eleven-ring PPV oligomer as a function of carbon site (hole fixed on site 34) for the excited stales corresponding to (a) die first absorption peak (3.0 cV) (b) the second absorption peak (3.8 eV) (c) the third absorption peak (5.6 eV) (d) lire fourth absorption peak (6.3 eV) and (e) lire fifth absorption peak (7.0 cV). The energies given between parentheses refer to the theoretical values.

These items are also described in Lancaster s book on page 106, They are so named because the fire dust sparks drop to remind us of waterfalls. They are prepared as follows(Fig.129) Charge a waterfall composition which contains aluminium powder of relatively large flakes into strong paper tubes which have a thin wall which burns away. (See also 15.10.) Put a quantity of ignition composition in the end of each tube. Make holes in it from the outside and pass a piece of wire which is wound with a piece of powder pasted paper through the hole. Fix the waterfall units made in this way to a hemp rope at intervals of about 50 cm. Connect the igniting ends with a line of piped quick match.

The mass-transfer devices may be sieves (holes), fixed valves, moveable valves, or bubble caps. Fig. 2 shows a selection of mass-transfer devices. The purpose of the device is intimate mixing of the vapor and liquid on the tray deck. An ideal device has high capacity, high flexibility, low leakage, low pressure drop, and low cost. 

Larger current sizes have bolt-hole fixings. 

When directed towards the test piece the laser beam passes through a centre hole in a 45 degree fixed-angle mimor. Between this mirror and the test piece the laser beam and the flourescence follow a common beam path. A photodetector is aimed at the 45 degrees angle mirror and, therefore, looks along the laser in this common beam path, see Fig 3.

Several forms of apparatus employing electrical heati iig wi 11 be described. A simple form may be readily constructed from a domestic electric iron of 400-500 watts rating. The handle is removed, and two holes of 8 mm. diameter are drilled through the base (ca. 11 mm. thick) so that they meet in the centre of the block. One hole is for a 360° thermometer (small bulb) the other hole is spare and can be used for comparison with a standard thermometer. The heater is mounted on a sheet of thick asbestos board which is fixed to an appropriate wooden base. The wires from the heating unit are connected to two insulated terminals fitted on the board (Fig. 11, 11, 1). The rate of heating is controlled by either of the following methods ... 

Another common system is the fixed knife mill. This consists of a chamber containing fixed knives and a rotating three-armed spider that shreds the fmit by forcing them against the fixed knives. Fmit are gravity fed into the chamber from an opening in the top. Small holes under the knives permit the mash to fall through to a conveyor. 

Electrochemical deburring is a fast process. Typical process times are 5 to 30 s for smoothing the surfaces of manufactured components. Owing to its speed and simplicity of operation, electrochemical deburring can often be performed using a fixed, stationary cathode tool. The process is used in many apphcations, and is particularly attractive for the deburring of the intersectional region of cross-drilled holes. 

The number of tube holes in a given shell is less than that for a fixed-tube-sheet exchanger because of hmitations on bending tubes of aveiy short radius. 

Pellet Mills Pellet mills operate on the principle shown in Fig. 20-92. Moist, plastic feed is pushed through holes in dies of various shapes. The friction of the material in the die holes supplies the resistance necessary for compaction. Adjustable knives shear the rodlike extrudates into pellets of the desired length. Although several designs are in use, the most commonly used pellet mills operate by applying power to the die and rotating it around a freely turning roller with Fixed horizontal or vertical axis. 

In the constant-strain method, the specimen is stretched or bent to a fixed position at the start of the test. The most common shape of the specimens used for constant-strain testing is the U-beud, hairpin, or horseshoe type. A bolt is placed through holes in the legs of the specimen, and it is loaded by tightening a nut on the bolt. In some cases, the stress may be reduced during the test as a result of creep. In the constant-load test the specimen is supported horizontally at each end...

Another variation is to use a thin air jet around a process or an opening to a pt(x ess. For welding or soldering on a table, a circular tube with supply holes in the upper side could be used. The circular tulw is placed around a fixed welding (soldering) place and blow s upward around the welding point into a basic opening hood. 

In canned pumps the rotor (the moving part of the electric motor) is immersed in the process liquid the stator (the fixed part of the electric motor) is separated from the rotor by a stainless steel can. If there is a hole in the can, process liquid can get into the stator compartment. A pressure relief plug is therefore fitted to the compartment and should be used before the compartment is opened for work on the stator. One day, an operator opened the pump without using the pressure relief plug. There was a hole in the can which had caused a pressure build-up in the stator compartment. When the cover was unbolted, it was blown off and hit a scaffold 6 feet above. On the way up it hit a man on the knee and the escaping vapor caused eye irritation. The worker was not familiar with canned pumps and did not realize that the pressure relief plug should be used before opening the compartment. 

A distilling flask ( litre) is fitted with a double-bored cork. Through one hole a thermometer is inserted, the bulb of which must be covered by the liquid in the flask and through the other a tap-funnel passes. The side-tube of the distilling flask is fixed by a coik into the upper end of a long condenser. An adapter is fitted to the lower end and passes through the neck of a flask, which is surrounded by ice. The apparatus is shown...
