Displacement, size, motive power, speed, radius of action, and armament were gradually increased until the "E" class contained boats possessing the following features: Submerged displacement, 800 tons; length 176 feet; beam 22-1/2 feet; heavy oil engines of 2000 H.-P.; electric engines of 800 H.-P.; surface speed 16 knots; submerged speed 10 knots; cruising range 5000 miles; armament: 4 torpedo tubes, space for 6 torpedoes, and two 3-inch quick-firing, high-angle, disappearing guns; armoured conning-towers and decks; wireless equipment; 3 panoramic periscopes.
The wire filament is formed into a loop like that of an incandescent lamp and its outside ends are connected with a 6-volt storage battery, which is called the A battery; then the + or positive terminal of a 22-1/2 volt dry cell battery, called the B battery, is connected to the metal plate while the or negative terminal of the battery is connected to one of the terminals of the wire filament.
The barometer stands at about 22-1/2 inches, and our thermometer gave the boiling point of water at 199 degrees. We could never get eggs well boiled in the high lands, and attributed this, whether rightly or not I cannot say, to the low temperature of boiling water.
As it was just daylight we were enabled to see the scenery at that point and Kicking Horse Pass. From the summit of the Rocky Mountains, for some nine miles, the line is considered to be merely a temporary one, though permanently and strongly constructed, there being a grade for two or three miles of it of 4-1/2 feet per hundred, say 1 in 22-1/2.
The apparatus you need for this set includes: a loose coupled tuning coil, a variable condenser, two fixed condensers, a crystal detector, or better a vacuum tube detector, an A or 6 volt storage battery, a rheostat, a B or 22-1/2 volt dry cell battery, a fixed resistance unit, or leak grid as it is called, and a pair of head-phones. The Vacuum Tube Amplifier.
The entire Illinois Freight Association gave an audience to the Warden of the Penitentiary and representatives from the Agricultural College and a uniform freight rate has been granted of one-half cent per ton per mile. This will enable us to secure ground limestone delivered at Heart-of-Egypt for $1.22-1/2 per ton.
The smallest A or 6 volt storage battery on the market has a capacity of 20 to 40 ampere hours, weighs 13 pounds and costs about $10.00. The B or dry cell battery for the vacuum tube plate circuit that gives 22-1/2 volts can be bought already assembled in sealed boxes.
The average length of a transport's voyage from the United Kingdom to Cape Town, as determined from 162 records, was 22-1/6 days. With them, and their one predecessor, 6,000 additional troops were at the latter date five weeks after the Boers' ultimatum became operative landed at the far base of operations, yet 500 miles by railroad from the front.
The Government sold 3000 old muskets at 22-1/2 per cent, of their cost. The purchaser becoming insolvent paid only 13 per cent. of the price he agreed to pay; that is, he paid $900. What did each musket cost the Government? Give operation in full. Question 7.
For this set you require: one variocoupler; two variometers; one .001 microfarad variable condenser; one .0005 microfarad variable condenser; one 2 megohm grid leak resistance; one vacuum tube detector; one 6 volt A battery; one 200 ohm potentiometer; one 22-1/2 volt B battery; one .001 microfarad fixed condenser, and one pair of 2,000 ohm headphones.
