Powder pasted paper or cloth

Generally we manufacture two kinds of pasted paper or cloth those with black powder and others with red thermit. The former is used for ordinary ignition and the latter for high temperature ignition. For the manufacturing process see the Lancaster s book on pages 245 246. [Pg.198]


It may well be a Japanese custom to sit on the floor to assemble shells, but it is rational, for it is possible to arrange all the components and tools around the worker and to avoid the shock caused when things fall on the floor. (But as described later, for shells which require less explosive than Warimono a working bench is often used in ordinary manufacture.) The operator must take care not to build up a mass of material around the working area. When chlorate compositions are used, have a wet cloth to hand, and wipe the hands with it immediately after handling each composition. Cutting powder pasted paper or quick match must be done in another room. [Pg.242]

Mechanical polishing is generally first done with fine emery paper. Care must be taken to work across the lines (scratches) formed on the surface by continual random rotation of the sample. Then alumina powders of different grades (on different felts) or diamond pastes of different grades (on different cloths) are used to remove, as well as possible, the disturbed layer.t A mirror finish should be observed for instance, no trace of the lines due to the polishing should appear when observation is magnified 20 times. [Pg.33]
