Speed of operation

Microprocessors (transputers), with the help of a special language (Occam), can handle flows of information in a parallel fashion instead of sequentially (serially), thereby greatly increasing the speed of operation. Transputers also control the flow of information by communicating with each other. 

Selection. The magnetic pulley width should match that of the belt. The face width is normally 51 mm wider than the belt width up to 1067 mm wide, and 76 mm on widths ia excess of 1219 mm. The speed of operation of the conveyor belt should be determined by calculating the maximum capacity to be handled. Using this iaformation, the diameter of the pulley required to handle the capacity can be determined (Table 2). The operating belt speed must be acceptable for the diameter selected. If the recommended belt speed is exceeded, the pulley diameter that can handle the belt speed must be used. 

There are many techniques available for measuring the particle-size distribution of powders. The wide size range covered, from nanometers to millimeters, cannot be analyzed using a single measurement principle. Added to this are the usual constraints of capital costs versus running costs, speed of operation, degree of skill required, and, most important, the end-use requirement. 

The phenomenon of a switching surge is related to the performance of the switching device, i.e. its speed of operation and ability to quickly rebuild its dielectric strength (deionization of the arc phisma) between the parting contacts after a current zero. 

Although the operating time of relays often varies between wide limits, relays are generally classified by their speed of operation as follows ... 

Sometimes it is advantageous or economical to use two or more pumps in series (one pump into and through the other) to reach the desired discharge pressure. In this situation the capacity is limited by the smaller capacity of any one of the pumps (if they are different) at its speed of operation. The total discharge pressure of the last pump is... 

At any constant or steady speed of operation of a compressor, the head-capacity and efficiency curves are characteristic of the impeller and casing design only. These curves that are determined by test can be translated to other reasonable speeds and conditions of operation of the wheel-casing combination of the affinity laws. The operation of the compressor must meet or establish the desired point on the head-capacity-system curve, which requires a combination of controls. 

The volumetric efficiency varies with the speed of operation, being lower at lower speeds and higher for low discharge pressures. As a general guide, the orders of magnitude of efficiencies are as follows ... 

This type of blade is well suited to streamline flow conditions and is used extensively on ventilating, air conditioning, and clean and dirty process gas streams. The backward blade does not catch dirt easily. The outstanding and important characteristic is the nonoverloading horsepower. This is the only commonly used blade style with this feature. It is important in process control and eliminates the need for oversized motors or other drivers. Speed of operation is high, which allows direct or belt connection to the driver. Certain streamlined blade designs provide the same basic characteristics with more efficient and quieter operation. The usual... 

Table 1 summarises the features of equipment design which influence the risks of odour problems arising from surface spreading. There are numerous combinations of these features to be found in slurry tankers however, tanker design is often directed more to productivity in terms of speed of operating and area of ground covered rather than to minimising odour and aerosol production. 

Although AIMB is a working prototype, we have many questions remaining to be answered. We would like to explore the detailed heuristics and study the effect of changing these on the final models constructed. We are interested in seeing how the size of the knowledge base is related to the quality of results and speed of operation. Finally, we would like to explore its application in areas where conventional methods simply can not be used. 

Owing to the volatility of cyanogen iodide, the yield is slightly dependent on the speed of operation. By the above method sublimation as a means of purification is avoided. If, however, sublimation is desirable, it can be accomplished with appreciable speed only under reduced pressure and at temperatures at which cyanogen iodide is slowly decomposed into iodine and cyanogen. The vacuum must be constantly renewed during the operation. 

Computers in general have traditionally been distinguished by a number of characteristics. The two foremost characteristics generally cited are, the word size which the computer uses and the speed of operations performed by the computer. 

Figure 20 Plate revolutions simulated for varying spheronization times for three spheronizers of increasing scale from two manufacturers, A and B. Each simulation is at maximum recommended speed of operation. Each rpm in the legend for A or B represents a spheronizer of a specific diameter (scale).

A good gas chromatographic column is considered to have high separation power, high speed of operation, and high capacity. 

Reichert and Linckens [83] have reviewed gas chromatographic methods for the determination of nitriloacetic acid in potable waters. They point out that esterification of the nitriloacetic acid is required to enable it to be volatilised in the gas-liquid chromatographic column, and they compared a range of esterification reagents and conditions for simplicity and speed of operation. The method chosen involved treatment of a concentrated sample with a mixture of -propanol-acctyl chloride (10 1) and the resulting nitroacetic acid-propyl ester injected into a column, which was fitted with a nitrogen-sensitive detector. The detection limit for nitriloacetic acid in potable water is about lpgL-1.
