Three-cylinder design

A chlorine cylinder design includes three fuse plugs (which melt at 165° F or 74° C) in each end. The heat from steam reportedly melted the plugs and the chlorine escaped through 3/8-inch (0.9 cm) diameter orifices. (See Chapter 3 for details.) (A tragedy also occurred when a steam hose was used on an ice cream refrigeration unit in Chapter 4.)... 

Table 1 shows the three mix designs the six different tests performed to the plastic modified concrete. Axial compression on concrete cylinders was tested in two different mix designs, No. 1 and No. 2. The other properties were examined only for one of the mix designs.

Actuators for control valves come in three basic designs pneumatic, electric, and hydraulic. Pneumatic actuators, which convert air pressure to mechanical energy, use three designs diaphragm, piston, and vane. Electrically operated actuators convert electricity to mechanical energy. Common examples include solenoid valves and motor-driven actuators. Hydraulically operated actuators convert liquid pressure to mechanical energy. The hydraulic actuator uses a liquid-tight cylinder and piston to move or position the valve stem. 

Welded cylinders are specified in DOT-4 or DOT-8 series of specifications. Welded cylinders are assembled from preformed components consisting of two half shells for a capsule type with center girth weld, or two heads with a formed body for a longitudinal three-piece design. Automatic submerged arc welding is used... 

In a duplex pump, the flow splits into two cylinders inside the pump, whereas in a triplex it splits into three cylinders. Table 9-2 compares both designs.

Plunger pumps are available with one, two, three, four, five, or even more cylinders. Simplex and duplex units are often built in a horizontal design. Those with three or more cylinders are usually of vertical... 

Two of the machines will operate full-time the third will serve as a standby. For such a situation, the suction header would be sized for the suction capacity of two machines. In practice, it may be better to run all three machines at reduced speed. Then when one comes down for some reason, the other two can speed up to carry the full load. Of course, this type of operation cannot be accomplished with a fixed speed drive. For the situation described, the design load is still the full capacity of two machines or four cylinders. 

As mentioned by Mathias et al. [9], reliable methods to measure the thermal conductivity of diffusion layers as a function of compression pressures are very scarce in the open literature. Khandelwal and Mench [112] designed an ex situ method to measure accurately the thermal conductivities of different components used in a fuel cell. In their apparatus, the sample materials were placed between two cylindrical rods made out of aluminum bronze (see Figure 4.28). Three thermocouples were located equidistantly in each of the upper and lower cylinders to monitor the temperatures along these components. Two plates located at each end compressed both cylinders together. The temperatures of each plate were maintained by flowing coolant fluids at a high flow rate through channels located inside each of the plates. A load cell was located between two plates at one end so that the compression pressure could be measured. 

The binding change mechanism for the trimeric Fi component resembles the action of a Wankle (or rotary) engine used in some automobiles. Fi s cylinders are made up of three identical polypeptide chains, and each protomeric unit is in a different conformation (designated L for Loose , T for Tight , and O for Open ). ADP and Pi bind to the L-site. Then, an energy-driven step occurs that successively converts L-ADP-Pi to T-ATP and T ATP to O + ATP ... 

Plunger pumps are available with one, two, three, four, five, or even more cylinders. Simplex and duplex units are often built in a horizontal design. Those with three or more cylinders are usually of vertical design. The driver may be an electric motor, a steam or gas engine, or a steam turbine. This is the common type of power pump. An example, arranged for belt drive, is shown in Fig. 10-28 from which the action may be readily traced.
