Illustrations proper handling

Bruised or damaged fruit can not be made attractive, and its use involves heavy waste. The proper handling of the fruit is therefore very important. Apricots, peaches, pears, etc., should be handled in shallow boxes which will not hold more than a bushel and will not admit of more than three or four layers of fruit. The top should be protected with cleats, so that one box can be set upon another without touching the fruit, thus insuring some ventilation. The email fruits-=-strawberries, raspberries, blackberries, and loganberries—are handled almost exclusively in chests, which are illustrated in detail in Plate II. The California packers have developed this part of the business to a... 

During scale-up of the catalyst production, one might experience deviations from ideal catalyst morphology with spherical particles following a normal distribution of particle size. Some artifacts are illustrated in Fig. 7, notably the appearance of a separate distribution of very fine particles and agglomerated particles, respectively. Proper handling and production will eliminate such effects. 

In this chapter, we have described a novel design approach to correct flow nonuniformities caused by four types of production variations in a linearly tapered coat-hanger die. The theoretical approach is based on the onedimensional lubrication approximation and can be used to predict the taper function of an adjustable choker bar. Once a choker bar is constructed based on the prediction of the mathematical model, the flow nonuniformities can be properly eliminated by inserting this bar into the die. A choker bar can be tapered in different ways as indicated in Fig. 3. The shape displayed in Fig. 3a may be easier to machine and was selected for illustration. The four production variations we have considered include (i) enlarging the manifold, (ii) including the fluid inertial terms, (iii) varying the viscosity of the polymeric liquids, and (iv) narrowing the liquid film width to meet production requirements. All these four production variations can be properly handled, but if the fluid inertia becomes dominant, or the Reynolds number is not small, the present method may not be applicable. 

Figure 6-32 illustrates ejector systems with large condensable loads which can be at least partially handled in the precondenser. Controls are used to maintain constant suction pressure at varying loads (air bleed), or to reduce the required cooling water at low process loads or low water temperatures [2]. The cooler W ater must not be throttled below the minimum (usually 30%-50% of maximum) for proper contact in the condenser. It may be controlled by tailwater temperature, or by the absolute pressure. 

Project managers find many opportunities to provide feedback to those who have a hand in completing the project. Through feedback, individuals learn about the effect their behavior has on others and on the project s success. It serves to maintain good performance and correct poor performance. To be effective, however, feedback must be handled properly. This illustration shows the continuous loop that exists when there is good feedback ... 

If removal is not expertly handled in problematic cases, considerable scarring can result, and some users have proceeded to litigation as a consequence of such complications. Complications in the removal of Norplant capsules have been evaluated in 3416 cases from 11 countries (48). Complications were reported in 4.5% of removals, usually attributable to implants being broken during removal (1.7%) or being embedded below the subdermal plane (1.2%). Logistic regression analysis showed that the most important risk factors for complicated removals were complications at insertion and an infection at the implant site (before or at the time or removal). For women without complications, the mean removal time was 12 minutes, but for those with complications the mean increased to 30 minutes. These results illustrate the necessity of proper insertion technique, under aseptic conditions. Capsules become surrounded by a fibrous sheath within 3 months after implantation beyond a few months, there is no difference in complication rate by duration of use. 

Other modules take care of equipment sizing and cost estimation, perform numerical calculations, handle recycle calculation (described in more detail below), optimize, and serve as controllers (executives) for the whole set of modules so that they function in the proper sequence. Figure 5.11 illustrates the information flow in a fiowsheeting package composed of modules. 

Once it has been verified that the data can be properly fit to a one-compartment bolus IV model, a linear regression analysis is performed on the data, with time (t) entered as the independent (x) data, and In(Cp entered as the dependent (y) data. Linear regression analysis can be performed on calculators that handle two-variable statistics, or using spreadsheet, graphing, or statistical analysis software on a computer. The analysis should provide values for the intercept (b) and the slope (m) that provide the best possible fit to the measured data in the form y = b + mx, as illustrated in Figure 10.23. The linear regression analysis also often provides a value called the correlation coefficient (r). 

Sodium, used as a heat transfer fluid, can most effectively remove heat from a fast breeder reactor. Development work on sodium handling at Argonne National Laboratory in 1945 led to the first turbine-electric power from nuclear energy in 1951. This paper presents the engineering mock-up of the experimental breeder reactor II and illustrates associated pumps, valves, and instrumentation. The past year s successful operation of the EBR-II mock-up has demonstrated that sodium technology is adequate for the job. Properly used, sodium may be the key to the problem of really using the elusive atom. 

A very important part of successful project development is the organization of personnel within the company to handle the various aspects of the job. Figure 2-1 shows a typical organization chart for industrial research. As the project develops, it is essential to obtain suggestions and criticisms from personnel in various departments from time to time. This can be done by conferences and/or circulation of progress reports. Communications problems must be solved for effective cooperation. The proper method to employ depends on the size and physical setup of the company. As a further illustration of the requirements for cooperation and communications, Table 2-1 shows how each of seven departments was involved during various phases of the development of a chemical product. 

Since, in the last section, the base-case operating condition that optimizes TAC is not able to handle properly the impmity disturbance changes in the +20% range, the side-stream flowrate is set to be higher than the optimum case of 50 kg/h in order to handle these disturbances better in the feed F3. A side-stream flowrate of 60 kg/h is used here for illustration purposes. Notice that when the side-stream flowrate increases from 50 kg/h to 60 kg/h, the TAC only increases by 0.66% (see Fig. 9.33). 

With proper-base line correction it is also possible to follow the kinetics. While isothermal kinetics is rather easy to evaluate, as is illustrated in Sect. 2.1.3, nonisothermal kinetics is somewhat more involved. The basic equation for nonisothermal kinetics is given in Fig. 2.9. An application and discussion is given in connection with the treatment of thermogravimetry in Sect. 7.5. Calorimetry of nonisothermal kinetics can be handled analogously. 

Instructing your workers in proper pipe handling is essential to your success. Know and understand the materials you are working with. Handle them accord-ingy. Once the materials are on the job site, you will need to provide proper storage conditions. Thermal expansion and contraction of plastic pipe is illustrated in...
