Container chime

Instructor Web Site is a text-specific site containing some of the assets as found on HM ClassPresent and HM ClassPrep as well as links to Chime and other useful instructor aids. 

Figure 9.7. Various linear notation schemes for chemical representation. Some contain only atom types and connectivity (WLN, ROSDAL, SMILES, SLN) and are chemist-readable. Others are compressed versions of molecule file formats (CHIME) and are meant for computer interpretation.

Since pails are small enough to be handled manually, steel handles are often attached for this purpose. It is also common to reduce the diameter of the bottom or top chime to facilitate stacking. These containers are widely used in the pharmaceutical industry for the in-house handling of tablets. Tight-headed pails with one closure only are often fitted with specially shaped tops which have a raised portion instead of a recess above the double seam. This is known as an interrupted chime, and its purpose is to allow the pails to be stored in the open without the risk of water accumulating in the head and penetrating the closure by capillary action. 

Aluminium aerosols are inherently more expensive than tinplate but can be made in one piece with neither side seam nor bottom chime. However, for practical or economic reasons these Monobloc containers are usually restricted to the smaller sizes of aerosol. Larger sizes are produced in two pieces, i.e. with a continuous side wall and a seamed-on base. In the past few years the process of drawing and wall ironing has enabled continuous side wall containers to be produced from both aluminium and tinplate sheet. Unlike two-piece extruded body containers, these containers have no base chime but instead have a seamed-on cone. When two different metals are involved, e.g. aluminium body and tinplate base, additional product compatibility checks must be carried out due to the risk of electrolytic corrosion. Again special coatings are available to inhibit this effect. 

Chime n. The top ring of a coating container into which the friction top is pressed in order to effect an air-tight seal. Syn chimb and chine. 

The most important Plug-In for chemistry is Chime from MDL Information Sy.stems. Chime contains all the functionality of rasmol plus 2D-display features and extended script-ability for animations. A professional version which interfaces to MDL databases is also available. Chime is available for IRIX, PC, and Macintosh platforms, but not for anything else. Chime applications are described in Internet-based Computational Chemistry Tools. 

Chemscape Chime a Netscape Navigator plug-in that allows researchers to view chemical structures contained in HTML pages or tables. Chime is available for free from MDL s website.
