Canvas tables

The chief machine and devices employing principle (3) are the round and canvas table. For sulphide ores and material which is adapted to saving by methods of flotation the preference would be flotation rather than these devices if only one method is employed. The methods of flotation, while not the panacea for dressing problems that they were originally supposed, recover more in the size range to which principle (3) is applicable from about 80-mesh to the smallest which are visible to the eye. If desired flotation can precede machines employing this third principle or it can come after provided it is desired to recover an extra modicum which would not be yielded by flotation alone. Flotation like other methods is weak on the very finest material and while it is the practice to submit all the very finest material made to it provided it is of the kind which will float there are serious losses in the very finest sizes. 

Cotton has been successfully combined with other materials to create fabrics for specific purposes. Table 4.4 lists some of these fabrics. Cotton fabric has also been given various names depending on the coarseness or fineness of the weave, and its intended use. These include calico, canvas, batiste, cheesecloth, muslin, organdy, cotton gabardine, gingham, lawn, voile, ter-rycloth, and cotton flannel. 

Once I ve established that I don t have the smallpox, I put on a bunchy woolen dress sewn by Mrs. Gill, then a canvas apron. When I have stuffed my hair into a cap, I am ready to make the journey to the kitchen, where my breakfast is on the table. 

Typical ATR crystal materials are listed in Table 4.6. Samples must be in actual intimate physical contact with the ATR crystal. The first ATR systems were designed to analyze solids that could be pressed against the surface of the crystal polymers, films, moldable resins, textiles, canvas paintings, and the like. Little or no sample preparation is required. For example, the IR spectrum of a valuable painting could... 

The development of film-to-film adhesion (canvas/canvas peel strength, ASTM-D-1876) with bonding after 30 min open time is shown in Fig. 19 for the two formulations given in Table 15.
