Manifold housings

The height of the spacer plate must be adapted to the height of the HR system so as to ensure the initial clamping of manifold and nozzles (see Chapter 4.2.1.2). 

The space housing the manifold must be closed off to prevent heat losses arising from an air draught. If the manifold space is not totally enclosed, it may be closed off by plates bolted onto the outside of the mould. 

The electric leads for heaters and thermocouples are located in grooves milled in the mould plates, and normally run to the top of the mould, on which a standard socket-contact is fastened.

Fig. 4. Schematic of a hemodialyzer. The design of a dialyzer is close to that of a sheU and tube heat exchanger. Blood enters through an inlet manifold, is distributed to a parallel bundle of fibers, and exits into a coUection manifold. Dialysate flows countercurrent in an external chamber the blood and dialysate are separated from the fibers by a polyurethane potting material. Housings are typically prepared from acrylate or polycarbonate. Production volume is...

Evaporation of Samples. Six samples of usually 250 ml. each are simultaneously evaporated to a moist residue in a water bath, shown in Figure 7, which is maintained at 80° to 90° C. The exhaust manifold is connected with the house vacuum. With the assemblies shown a gentle stream of air is drawn over the surface of the evaporating solution and out the vacuum line the air inlet tube is lowered frequently so as to maintain a rippled surface on the benzene extract. In this manner, 250 ml. of benzene can be evaporated completely in 10 minutes or less. 

The benzene strip or extract solutions are evaporated nearly to dryness in 500-ml. standard-taper Erlenmeyer flasks on 3 units of a 6-unit variable heat extraction apparatus hot plate (see Figure 1). Evaporation is hastened by directing a jet of air at the surface of the benzene, gentle enough to avoid spattering when maintained 0.5 inch above the surface of the liquid. The benzene vapors are removed through a manifold connected to the house vacuum. On this apparatus 250 ml. of sample can be reduced to a volume of about 5 ml. in 10 minutes.

Yan et al. [27] manufactures an instrument, which can be operated in both CEC and micro-HPLC mode. The high voltage power supply can provide up to 60 kV. A stainless-steel six-port rotary valve that also includes an injection port serves as the injection manifold, which is inserted in the electric circuit. The instrument is partially housed within a Faraday cage. 

A full-scale model of the air intake manifold, where the complete sensor (with signal processing ICs, housing, cable fittings, etc.) can be tested under real-life conditions, was available. However, failure rates of components in automotive applications under normal conditions are on the order of a few ppm, which corre-... 

The use of a tubular membrane is very attractive due to its malleability and flexibility and the ease with which it can be directly incorporated in the flow manifold. The membrane is generally housed inside conventional tubing (made of plastic or metal), establishing a concentric geometry [263,264]. The donor and acceptor streams flow on either side of the tubular membrane (Fig. 8.21, lower). Analyte diffusion takes place in... 

One advantage of miniaturization is that the entire system could be easily moved to another location for maintenance. Figure 12.16 compares the AIMS to the flow manifold for a MARS Version VI. An oven that houses the MARS parallel reactor bank was removed from the hood to provide a clearer perspective view. The front area of the AIMS occupied about one-tenth of the area of the MARS flow manifold. Obviously, the AIMS offers a significant advantage by reducing the space requirements in a fume hood. In addition, an operator can easily access all of the parts of the AIMS without needing a footstool or stepping inside the hood.
