Figure 2.21(b). Kossel diagram of the Blue Phase 11 seen along the threefold symmetry axis [111]. The apparent sixfold symmetry of the experimental diagram is due to the reflection of light on the surface of the cylinder glass in the cell. Due to this reflection the diagrams from the north and south hemispheres are superposed.

Figure 3.10 Flat glass recent history. Plate (cast and rolled) versus sheet (crown and cylinder) glass division vanishes with Float glass revolution. Meanwhile, they were automated from 19(X).

Nessler tubes Cylinders of thin glass, generally graduated, used for comparing turbidities and colours of solutions. 

To verify the modelling of the data eolleetion process, calculations of SAT 4, in the entrance window of the XRII was compared to measurements of RNR p oj in stored data as function of tube potential. The images object was a steel cylinder 5-mm) with a glass rod 1-mm) as defect. X-ray spectra were filtered with 0.6-mm copper. Tube current and exposure time were varied so that the signal beside the object. So, was kept constant for all tube potentials. Figure 8 shows measured and simulated SNR oproj, where both point out 100 kV as the tube potential that gives a maximum. Due to overestimation of the noise in calculations the maximum in the simulated values are normalised to the maximum in the measured values. Once the model was verified it was used to calculate optimal choice of filter materials and tube potentials, see figure 9. 

The extractor consists of a glass cylinder A, terminating at the base in the open tube B. Fused within the top of A as shown is another tube C, having a small hole D blow n in the side a fine glass tube leads from the base of C, rises about two-thirds of the height of the cylinder to E, and then returns past F into the open tube B. 

Spray. For most purposes a simple spray device, based on the ordinary scent-spray, suffices. A finer and less intermittent spray can be obtained using the apparatus shown in Fig. 26. A narrow glass cylinder J has a ground-glass... 

When the solvent around the spot has evaporated, the plate is placed ertically in a glass developing tank (a cylinder for small slides) which contains a small quantity of the solvent and is lined with filter-paper dipping into the solvent the level of the latter is adjusted, preferably with a pipette, so that the lower edge of the absorbent layer is under the soh ent but the spot is above this level, and the top of the cylinder is then firmly closed. The solvent rises through the adsorbent layer, and the components of the mixture ascend at different rates depending on their affinities for the adsorbent. 

Meanwhile, prepare a pellet of the substance, using a pellet press of the type shown in Fig. 78 (p. 431), but having the cylinder C of about 3 mm. internal bore to enable a pellet of 20-50 mg. to be compressed and then ejected. (Do not compress the pellet more than is necessary for manipulation, otherwise it may dissolve too slowly in the boiling solvent.) Transfer the pellet to a watch-glass, which preferably should be kept in a small desiccator before and after weighing. 

The apparatus depicted in Fig. 11,34, 1, intended for advanced students, may be used for the filtration of a small quantity of crystals suspended in a solvent either a Hirsch funnel or a glass funnel with Witt filter plate is employed. The mixture of crystals and mother liquor is filtered as usual through the funnel with suction. Rotation of the three-way tap wifi allow air to enter the filter cylinder, thus permitting the mother liquor to be drawn oflF by opening the lower tap. The mother liquor can then be applied for rinsing out the residual crystals in the vessel, and the mixture is again filtered into the cylinder. When all the crystals have been transferred to the funnel and thoroughly drained, the mother liquor may be transferred to another vessel the crystals may then be washed as already described (Section 11,32). 

Sulphur dioxide. Sulphur dioxide is avail-able in the liquid form in heavy glass cylinders the gas is obtained by simply turning the metal valve. 

Chlorine from a cylinder is passed through two wash bottles containing concentrated sulphuric acid, then through an empty wash bottle filled with glass wool to remove spray. 

Place 200 ml. of absolute ethyl alcohol in a 500 ml. aU-glass wash bottle, and cool to — 5° by immersion in a bath of ice and salt. Pass a slow stream of ammonia, derived from a cylinder and dried by passage through a tower filled with small pieces of quicklime, into the alcohol until the...
