Blowing charge

Now prepare the rocket head for the reception of the chain, as direrfted for parachute rockets, by placing about 2 feet of naked match in bottom of head for the blowing charge. Slip the bunch of lancet on top of this th... 

In bundles as shown on the right, for use in Candles. A bunch of crackers is made up to suit the bore of the Candle and a piece of tissue posted round to hold then together for loading. The piece of bare match will ensure ignition of the blowing charge. 

This model had an immediate nuclear problem because the positive charges in the nucleus repel each other. The nucleus should thus blow itself apart. This model clearly required a new force to hold the particles in the nucleus together. 

In the CIS pitch coke is made by carbonizing a hard coke-oven pitch in modified coke ovens. The hard pitch has an R-and-B softening point of 140—150°C and is made by air-blowing a mixture of medium-soft pitch and recycled coking oils. This feedstock is charged in the molten state over a period of 5 h and coked for 17—18 h at 1250—1300°C. The coke yield is 70%. Oils, which are recycled, amount to 20% by weight of the pitch fed. The gas yield... 

Large quantities of fines in the furnace charge cause furnace blows that are hazardous to operator and equipment. Blows result when the steady flow of mix to part of the melt zone is stopped by a fines bridge the calcium carbide Hquid overheats and then dissociates at 2250°C.

Pipe with high resistivity lining that contains semiconductive or nonconductive flammable liquids should be blown down with nitrogen rather than air. To avoid pinhole damage, the flow rate during blow-down should be no higher than normal liquid flow rate. Also, the possible hazards created in downstream tanks by charged, two-phase flow should be considered (5-2.5.4).
