Acid filling

Procedure. Weigh out accurately from a weighing bottle about 0.2 g of the pure sodium carbonate into a 250 mL conical flask (Note 1), dissolve it in 50-75 mL of water, and add 2 drops of methyl orange indicator (Note 2) or preferably of methyl orange-indigo carmine indicator (Section 10.9), which gives a very much more satisfactory end point (Note 3). Rinse a clean burette three times with 5 mL portions of the acid fill the burette to a point 2-3 cm above the zero mark and open the stopcock momentarily, in order to fill the jet with liquid. Examine the jet to see that no air bubbles are enclosed. If there are, more liquid must be run out until the jet is completely filled. Re-fill, if necessary, to bring the level above the zero mark then slowly run out the liquid until the level is between the 0.0 and 0.5 mL marks. Read the position of the meniscus to 0.01 mL (Section 3.12).

An example of this was a yellow body with a red band on the nose to denote high explosive, lyddite (Picric Acid) filled projectiles. When plaster kits were assembled to these projectiles a wide brown band was painted on the projectile nose and one narrow red band painted underneath it. In addition to the color markings, metal stamp and stencil markings were also employed for identification purposes...

Assemble an apparatus as shown in Fig. 102. Lubricate the ground-glass joints with phosphoric acid. Fill the apparatus with dry carbon dioxide using offtake 2. Pour 10 ml of dry carbon disulphide from dropping funnel 3 into flask 1. 

Dissolve 5 g phloroglucinol (1,3,5-trihydroxybenzene) and 1 g ascorbic acid in a minimum amount of methanol (60 ml) and transfer to a 100-ml volumetric flask. Add 0.5 ml of 10 N hydrochloric acid, fill to the mark with methanol, and mix well. Store up to 2 weeks at 4°C. Bring to room temperature before use. 

The nitrating acid is metered by means of tipping a vessel fixed on a horizontal shaft (Fig la). Acid flows into the vessel (1) from a pipe ending inside a container constructed of acid-resistant steel or lead, in which the tipping vessel is located. The stream of acid fills the vessel, and as a determined weight is reached it tips over and another empty vessel swings into place under the acid inlet pipe. This fills in turn and tips over to pour off its contents, and so the cycle continues. A volume-meter connected to the equipment indicates the volume of liquid... 

It is necessary to carry out the preparation under a hood. About 200 ml. of fuming nitric acidt (sp. gr. 1.60) contained in a 350-ml. tube (test-tube shape) is cooled with ice and salt, and sulfur dioxide is passed into it fairly rapidly. The reaction is exothermic, and the rate of addition should be such that the temperature of the solution does not rise above 5°C. In 6 or 8 hours, the crystals of nitrosylsulfuric acid fill the space of the original liquid, forming a compact mass with a layer of dark fuming liquid 2 to 3 cm.

Many of the ancient authors sing praises to the utility of vitriol. Basil Valentine called it The True Mineral Salt which contains the Red and the White spirits. If vitriol alone is distilled, there will first come over a clear liquid (the White spirit) with a strong sulfur dioxide odor. Keep this tightly sealed and the choking odor will disappear as the dissolved sulfur dioxide oxidizes to form a mild solution of sulfuric acid. As the heat is increased quite high, there will finally ascend a more viscous, reddish liquid which is a concentrated sulfuric acid filled with martial essence (the Red spirit).

Covers for the battery designs in Figures 1 and 2 are typically molded from materials identical to that of the respective case, and vent plugs are frequently made of molded polypropylene. Other combinations are possible, eg, containers molded of polyethylene or polypropylene may be mated with covers of high impact mbber for use in industrial batteries. After the cover is fitted over the terminal post, it is sealed onto the case. The cover is heat bonded to the case, if it is plastic it is sealed with an epoxy resin or other adhesive, if it is vulcanized mbber. Vent caps are usually inserted into the cover s acid fill holes to facilitate water addition and safety vent gasses, except for nonaccessible maintenance-free or recombinant batteries. In nonaccessible batteries, the vent is fabricated as part of the cover.
