Racking back

Place the test tubes back in the rack and the rack back in the water bath and let the color develop for about 5 minutes. 

Figure 12 shows the plan and elevation views of a process unit piping (9). A dmm is supported off the piperack. Heat exchangers are located far enough back from the support columns so that they are accessible and their shell covers can be removed. Pumps are located underneath the piperack, but sufficient room is provided for maintenance equipment to access the motors and to remove the pump if necessary. The motor is always oriented away from the process equipment and located on that side of the piperack. Instmment valve drops are shown supported from the columns. The instmment trays themselves mn on the outside of the support columns. Flat turns are only made from the outside position of the piperack. Nozzle-to-nozzle pipe mns are made whenever possible. Larger lines are located on the outside of the piperack. Connections to nozzles above the rack are made from the top... 

Place emulsion-coated slide in a horizontal position and wipe the back of the dipped slide with a paper towel or a damp sponge and place the slide flat on a drying rack protected from safelight exposure for 1 h at 45-50% relative humidity (RH). The emulsion will gel in approximately 1 h but can be speeded up by placing the slide on a cold metal plate for 15-... 

Begin with the test tube labeled pH3. Position the pH electrode in this test tube. Since the desired pH is more acidic than the pH of the red cabbage solution, add the 0.5 MHC1, dropwise, and stir with a glass stirring rod until the pH is about 3. Place it back in the rack. 

A fearful fit of coughing racked the little form and David held him gently in his arms until the paroxysm had passed. Then, laying the boy back upon the pillows, he said quietly ... 

The sample rack is unique in that it possesses pitch both front to back and side to side. A single robot pick-up point is defined, and an optical (IR) sensor constantly monitors the pick-up point for the presence of a sample. Vials placed in the rack roll down to the pickup point, under the influence of gravity. The rack allows implementation of a novel processing scheme. 

Automatic plating lines in which the movement of parts through the line are computer-controlled can increase drain time by augment the dwell times that parts spend above the process baths after they are removed. It also aids drainage to remove the parts as slowly as possible from the baths less fluid is entrained on the parts that way. On hand lines, when parts are removed from the baths, they can be hung on racks above the baths, or above drainage boards that drain back into the baths. 

UMEs used in our laboratory were constructed by sealing of carbon fibre into low viscosity epoxy resin (see Fig. 32.4) [118]. This method is simple, rapid and no specialised instrumentation is required. Firstly, the fibres are cleaned with this aim. They are immersed in dilute nitric acid (10%), rinsed with distilled water, soaked in acetone, rinsed again with distilled water and dried in an oven at 70°C. A single fibre is then inserted into a 100- iL standard micropipette tip to a distance of 2 cm. A small drop of low-viscosity epoxy resin (A. R. Spurr, California) is carefully applied to the tip of the micropipette. Capillary action pulls the epoxy resin, producing an adequate sealing. The assembly is placed horizontally in a rack and cured at 70°C for 8h to ensure complete polymerization of the resin. After that, the electric contact between the carbon fibre and a metallic wire or rod is made by back-filling the pipette with mercury or conductive epoxy resin. Finally, the micropipette tip is totally filled with epoxy resin to avoid the mobility of the external connection. Then, the carbon fibre UME is ready. An optional protective sheath can be incorporated to prevent electrode damage. 

Holmes had been sending her tapes regularly since moving back up to Sydney. They arrived with no notes, just one or several words. She sometimes didn t know if he had written the title or the artist or the label. Autechre, Illuminate the Planet, System 7. ReactTest Art of Trance Techno Slut Audio Psy Harmonics. Some of it she knew already. Others more clues to the racks in city record shops. Little by little the staff got to know her and a stack of new releases was set aside each time she went in. 

Squeegee the front and back of each print and place them on print drying racks with a nylon screen, either face up or down, or hang them with film clips in a dryer.
