Glass balls

The graph in figure 3.4.4 shows the pressure drop over 5.6 mm 0 glass balls. Generated pressure was not significantly different on these larger balls than it was over the 0.2 mm powder.

To use such pipettes, a suitable pipette filler is first attached to the upper or suction tube. These devices are obtainable in various forms, a simple version consisting of a rubber or plastic bulb fitted with glass ball valves which can be operated between finger and thumb these control the entry and expulsion of air from the bulb and thus the flow of liquid into and out of the pipette. Suction by mouth must never be used to fill a pipette with liquid chemicals or with a solution containing chemicals.

Earlier we have said that the flow of filled materials can be raised by modification. One of the modification alternatives consists in using a combination ( flexible ) filler. As shown in [366], addition of a small quantity of glass balls to composites filled with chalk caused a sudden increase of the flow of the system, provided the filler concentration is below critical. Similar behavior was also observed in fiber-filled systems when a small quantity of dispersed particles were added [33],... 

When uranium-235 nuclei are bombarded with neutrons, they can split apart in a variety of ways, like glass balls that shatter into pieces of different sizes. In one process, uranium-235 forms barium-142 and krypton-92 ...

In principle, Eq. (8.1) can be applied only for small scattering centers with small scattering cross sections. For extended centers (e.g., a cell, a glass ball) with high scattering cross section, Eq. (8.1) has to be replaced by... 

You can t do style on a shoestring, man Jacopo pirouetted, whirling his cape. He was showing off for my benefit, trying to persuade me that in private he was on equal terms with his brothers. Look— it s the buttons that make this outfit. My tailor used ugly little glass balls. I made him take it back and put these amethysts on. It cost ten times as much, but look at the result. ... 

Add 1.0 ml of Soln. F to the above pellet and heat the mixture to 90 °C for 1 h. It is recommended to close the test tubes with a glass ball to avoid dryness.

Figure 18.3 Ground-glass ball-and-socket joint with grooved O-ring seal. The physical contact between the socket and ball is minimized by the use of the O-ring, and the flexibility of the joint is increased. Lubricant is not essential to hold a vacuum.

An explosion-proof motor-driven grinder or steel or glass balls can also be used to grind the sample (see Critical Parameters).

Distillation is an ancient unit operation, and has been widely practiced for thousands of years. Early applicetions used crude vaporization and condensation equipment, often for concentrating the alcoholic content of beverages, The first vertical columnar continuous distillation still was developed by Cellier-Blumenthal in France in 1813. Perrier introduced an early version of the bubble-cep tray in England in 1822, Packings were used as early as 1820 by a technologist named Clement who used glass balls in an alcohol still. Coffey developed the first sieve tray column in 1830. The first book on fundamentals of distillation was La Rectification de I alcohol by Ernest Sorel in 1893.

Common industrial inorganic supports are [14] silica, porous glass, alumina, zeolites, ceramics, Aerosil, and glass balls. Prior to its use the porous silica glass, for instance, must be modified as shown in Eq. 12 with amino alkoxy silanes [141. 

In view of all these obvious or hidden drawbacks of methods I and II, a multicomponent saturator has been developed for the generation of gaseous feed streams in laboratory flow-type units [18, 19]. Its salient features (cf. Fig. 4) are a vertical saturator column packed with an inert solid, typically glass balls, and a moving liquid phase (as opposed to the saturators shown in Fig. 2) which trickles downwards, while the carrier gas A is conducted countcrcurrently. A pump conveys the liquid B + C-l----mixture from the storage vessel via a...
