Mounting pin

Another ak pollutant that can have very serious effects is hydrogen sulfide, which is largely responsible for the tarnishing of silver, but also has played a destmctive role in the discoloration of the natural patinas on ancient bronzes through the formation of copper sulfide. Moreover, a special vulnerabihty is created when two metals are in contact. The electromotive force can result in an accelerated corrosion, eg, in bronzes having kon mounting pins. [Pg.425]

Figure 2.4 One of Leeuwenhoek s microscopes front, back and side views. The tiny spherical or hemispherical lens is held in the slightly raised structure in the upper part of the metal plate. The object to be examined was mounted at the tip of the sharp-pointed mounting pin. Focusing was accomplished by means of the three thumbscrews to which the mounting pin is attached. These are approximately actual size. Figure 2.4 One of Leeuwenhoek s microscopes front, back and side views.

A ctyovial is selected and placed on a flat surface at ambient temperatures. This allows the external most layer of solid propane to thaw (c. 10 s) and will result in release of the loop/mounting pin from the cryovial. At this point, a substantial amount of propane will remain in solid form... [Pg.66]

The mounting pin (held by the magnetic crystal wand) is manoeuvred into the head of the cryotong. Encased within the head of the cryotong, the loop-mounted crystal will remain at cryogenic temperatures for up to 20 s. [Pg.66]

Larger button cells with rated capacities in the range 35-lOOOmAh are manufactured for direct mounting on printed circuit boards where they are used as standby power sources for CMOS RAMs, reference voltage sources, etc. Fig. 9.10 shows the construction of these cells and the position of the terminal/mounting pins. Projected discharge curves for Catalyst Research Corporation cells are given in Fig. 9.11. [Pg.285]

Method L Place a small amount ca. 2 mg) of the synthesized material in a glass vial and add 10 mL of methanol. Place the vial in a sonicator for half an hour. Place a drop of the suspension on carbon tape stuck to a mounting pin. Allow the methanol to evaporate completely and insert into the sample chamber. If FESEM images indicate an agglomeration of nanotubes, try preparing your sample from a chloroform suspension. [Pg.457]

Method 2. Simply place a small amount (spatula tip) of the black powder onto carbon tape fastened to an aluminum-mounting pin. Tap down the powder with the flat end of the spatula and shake off the excess prior to mounting in the SEM vacuum chamber. [Pg.457]

If a hacksaw is used, extend the length of the mount pins and install five blades on the frame. This should cut the correct width slot in one pass. Hacksaw blades are. 5" high, so epoxy a. 0625" wide strip along the side of the top edge to limit the depth of the cut to. 4375", If a miter box is available, set angle to 87 ... [Pg.37]

The Mounting Pin. In this laboratory the best results have been obtained with a specially designed mounting pin, illustrated in Figure 1. The pin is a hollow copper rod with a diameter corresponding to the adaptor hole in the goniometer head (normally 3 mm or 0.125 in). The tip of the pin is tapered down to 0.5 mm. The bore diameter near the tip is -0.5 mm the rest of the bore is 1.5 mm. In preparation for use the fine bore hole is filled with standard electronic solder (by capillary action). A glass fiber of... [Pg.260]

Disintegrators These so-called dynamic scrubbers consist of concentric rotor and stator mounted pins through which the gas stream is driven by means of a fan placed downstream or by fan blades at the outer end of the rotor. Water injected into the centre of the rotor, is broken into fine droplets by the pins and dispersed in the gas stream. The wet particles impinge on the stator walls and are collected at the bottom of the disintegrator. The system works efficiently when the gas flow is reduced. [Pg.211]

The lens of this headlamp was molded from polycarbonate (stiff, strong, impact resistant, and has excellent light transmission in its clear form). The lens itself was a Fresnel type lens and the part also had some molded-in mounting pins. We had a prototype mold fabricated to prove out the optics and when the first parts were tested we noticed some problems. The optics of the lens was fine, but the mounting pins were not quite strong enough. So we started exploring ways to improve the structure. [Pg.226]
