ICIFM-21SP Monopolar Electrolyzers. Id s EM-21 SP monopolar electrolyzer incorporates stamped electrodes that are 2 mm thick and of a relatively small (0.2 m ) size (50). The electrolyte compartments are created by molded gaskets between two of the electrode plates the electrode spacing is finite and is estabHshed by gasket thickness. The electrode frames are supported from rails and are compressed between one fixed and one floating end plate by tie rods. Inlet and outlet streams are handled by internal manifolds. A crosscut view of the electrolyzer is shown in Eigure 21. As of 1989, ICI had Hcensed 20 plants having an annual capacity of 468,250 t of NaOH. 

Plate and Frame. Plate-and-frame systems consist of plates (Fig. 15) each with a membrane on both sides. The plates have a frame around their perimeter which forms flow channels ca 1 mm wide between the plates when they are stacked. The stack is clamped between two end plates, sealing the frames together.

The second most commonly used header is a cover-plate header. The cover plate is bolted to the top, bottom, and end plates of the header. Removing the cover plate provides direct access to the tubes without the necessity of removing individual threaded plugs.

Fig. 28.8. Exaggerated drawing of the deflections that occur in the loaded drum. The shaft deflects under four-point loading. This in turn causes the end plates to deflect out of plane, creating tensile (-r) and compressive (-) stresses in the weld.

Moke end plate thicker (increase t in eqn. 28.10). Plate would have to be 70 mm thick heavy difficult to weld to collar might overstress plate-shell weld collar would become irrelevant. 

Increase shaft diameter and decrease end plate. thickness Increases / and decreases t in eqn. 28.10. Would need 250 mm diameter shaft + 1 5 mm thick end plate very heavy and expensive. Would still need to check plate-shell weld. 

Decrease shaft overhang - move bearings next to end plates. Requires major modifications to support framing or over-long shells. 

Use fixed (non-rotating) shaft and mount bearings in end plates. Probably the best solution, but no good for drive drums. 

Check bore and face-end plates for nicked edges, deep scratches, or scoring. Stone or scrape if necessary, and polish with very fine aluminum oxide polishing paper. 

By the early 1980s high-gloss DMCs using low-profile resins were finding use in kitchen appliances such as steam iron bases, toaster end-plates and casings for electric fires. 

Example 2.6 The bobbin shown in Fig. 2.16 has been manufactured by sliding the acetal ring on to the steel inner and then placing the end-plate in position. At 20°C there are no stresses in the acetal and the distance between the metal end-plates is equal to the length of the acetal ring. If the whole assembly is heated to 1(X)°C, calculate the axial stress in the acetal. It may be assumed that there is no friction between the acetal and the steel. The coefficients of thermal expansion for the acetal and the steel are 80 x 10 °C and 11 X 10 °C respectively. The modulus of the acetal at 100°C is 1.5 GN/m. ...

Fig. 6.6. One-dimensional, pressure-versus-location predictions at various times are shown for a typical powder compact subjected to baratol plane-wave explosive loading. The pressure is shown to ring-up to a final value between the copper end plates (after Graham [87G03]).

Electron microscopic study reveals an incalculably small space between nerve endings and the effector organ (eg, tlie muscle, cell, or gland) diat is innervated (or controlled) by a nerve fiber. Fbr a nerve impulse to be transmitted from die nerve ending (motor end plate) across die space to die effector organ, a neurohormone is needed. 

The somatic motor nervous system or voluntary nervous system consists of nerve libers that irmervate skeletal muscle motor end-plates.
