A careful inspection of both shaft ends must be made to ensure that no burrs, nicks, or scratches are present that will damage the hubs. Potentially damaging conditions must be corrected before coupling installation. Emery cloth should be used to remove any burrs, scratches, or oxidation that may be present. A light film of oil should be applied to the shafts prior to installation. Keys and key-ways (discussed in Section 59.3) also should be checked for similar defects and to ensure that the keys fit properly. Properly sized key stock must be used with all keyways do not use bar stock or other material. 

Avoid scratching or nicking bearing surfaces. Care must be taken when polishing bearings with emery cloth to avoid scratching. 

A commercial silver alloy in the form of wire or foil is suitable for this determination. Clean the alloy with emery cloth and weigh it accurately. Place it in a 250 mL conical flask, add 5 mL water and 10 mL concentrated nitric acid place a funnel in the mouth of the flask to avoid mechanical loss. Warm the flask gently until the alloy has dissolved. Add a little water and boil for 5 minutes in order to expel oxides of nitrogen. Transfer the cold solution quantitatively to a 100 mL graduated flask and make up to the mark with distilled water. Titrate 25 mL portions of the solution with standard 0.1 M thiocyanate. 

Notes. (1) Iron wire of 99.9 per cent purity is available commercially and is a suitable analytical standard. If the wire exhibits any sign of rust, it should be drawn between two pieces of fine emery cloth, and then wiped with a clean, dry cloth before use. The general reaction which occurs has been given in Section 10.92. 

Figure 3 shows a significant difference in thoron progeny activity plated-out on laboratory coat cotton cloth samples and Millipore filters (0.8 /un), and emery cloth. Differences between the two latter sample materials are not clear in these measurements. 

I and Table III for emery cloth as having the lowest plated-out activity. However, there is disagreement between cotton cloth and Fiberglas. This difference shows with both the weak and strong reference sources (see Table III). This experimental observation seems to rule out spurious or systematic errors.

When relocating probes, the electrodes should be cleaned and re-aged. Electrodes should be cleaned with emery cloth or steel wool to a dull shine and then degreased. After cleaning, do not touch the electrodes. 

Remove oxides and other contaminants from all the metals by polishing them with emery cloth. 

Polish the copper, first with medium emery cloth and then with fine emery cloth, to remove scratches and create a brushed finish. 

Remove the wax by placing the ring in warm water and wiping off the wax. Using fine emery cloth, polish the ring. 

Guiding surfaces may be polished using a fine emery cloth. The bellows and other metal parts may be cleaned using acetone or alcohol, then rinsed with clean tap water and dried. 

A stout platinum sheet (80 mm x4mm) formed the cathode metals (Fe, Co, Ni, Cu, Zn, Ag, Au) were cleaned with 5 mol/L HC1. They were finely polished with a fine emery cloth. Some reagents were used as supplied and others were adequately treated. The electrolyte (ca. 200 mg) was added to a 200-mL round-bottomed Schlenk flask into which THF and acetonitrile (typically 3 1 ratio) were distilled under Ar. Monomeric cyclopentadiene (ca. 4mL) was then condensed into it (similarly for methylcyclopentadiene). The flask was fitted with a...
