National guard units tried to seize power in Paris on 31 October 1870 and 22 January 1871. On 18 March 1871, when the regular army tried to remove cannons from an artillery park on Montmartre, National Guard units resisted and killed two army generals. The national government and regular army forces retreated to Versailles and a revolutionary government was proclaimed in Paris. A Commune was elected, which was dominated by socialists, anarchists and revolutionaries.

Bismarck honoured the armistice, by allowing train loads of food into Paris and withdrawing Prussian forces to the east of the city, prior to a full withdrawal once France agreed to pay a five billion franc war indemnity. At the same time, Prussian forces were concentrated in the provinces of Alsace and Lorraine. An exodus occurred from Paris as some 200,000 people, predominantly middle-class, went to the countryside.",

General De Wimpffen, the commander of the French V Corps in reserve, hoped to launch a combined infantry and cavalry attack against the Prussian XI Corps. But by 11:00, Prussian artillery took a toll on the French while more Prussian troops arrived on the battlefield. The French cavalry, commanded by General Marguerite, launched three desperate attacks on the nearby village of Floing where the Prussian XI Corps was concentrated. Marguerite was killed leading the very first charge and the two additional charges led to nothing but heavy losses. By the end of the day, with no hope of breaking out, Napoleon III called off the attacks. The French lost over 17,000 men, killed or wounded, with 21,000 captured. The Prussians reported their losses at 2,320 killed, 5,980 wounded and 700 captured or missing. By the next day, on 2 September, Napoleon III surrendered and was taken prisoner with 104,000 of his soldiers. It was an overwhelming victory for the Prussians, for they not only captured an entire French army, but the leader of France as well. The defeat of the French at Sedan had decided the war in Prussia's favour. One French army was now immobilised and besieged in the city of Metz, and no other forces stood on French ground to prevent a German invasion. Nevertheless, the war would continue.",

The French expected the invasion to divert German troops and to encourage Denmark to join in the war, with its 50,000-strong army and the Royal Danish Navy. It was discovered that Prussia had recently built defences around the big North German ports, including coastal artillery batteries with Krupp heavy artillery, which with a range of 4,000 yards (3,700 m), had double the range of French naval guns. The French Navy lacked the heavy guns to engage the coastal defences and the topography of the Prussian coast made a seaborne invasion of northern Germany impossible.",

    "title": "7: Elevator",
    "context": "Past problems with hydraulic elevators include underground electrolytic destruction of the cylinder and bulkhead, pipe failures, and control failures. Single bulkhead cylinders, typically built prior to a 1972 ASME A17.1 Elevator Safety Code change requiring a second dished bulkhead, were subject to possible catastrophic failure. The code previously permitted only single-bottom hydraulic cylinders. In the event of a cylinder breach, the fluid loss results in uncontrolled down movement of the elevator. This creates two significant hazards: being subject to an impact at the bottom when the elevator stops suddenly and being in the entrance for a potential shear if the rider is partly in the elevator. Because it is impossible to verify the system at all times, the code requires periodic testing of the pressure capability. Another solution to protect against a cylinder blowout is to install a plunger gripping device. One commercially available is known by the marketing name \"LifeJacket\". This is a device which, in the event of an uncontrolled downward acceleration, nondestructively grips the plunger and stops the car. A device known as an overspeed or rupture valve is attached to the hydraulic inlet\/outlet of the cylinder and is adjusted for a maximum flow rate. If a pipe or hose were to break (rupture), the flow rate of the rupture valve will surpass a set limit and mechanically stop the outlet flow of hydraulic fluid, thus stopping the plunger and the car in the down direction.",

The safety and speed of electric elevators were significantly enhanced by Frank Sprague who added floor control, automatic elevators, acceleration control of cars, and safeties. His elevator ran faster and with larger loads than hydraulic or steam elevators, and 584 electric elevators were installed before Sprague sold his company to the Otis Elevator Company in 1895.

The elevator will then travel non-stop to the selected floor, and will remain in code-blue service until switched off in the car.

The system lets them know which car to wait for, instead of everyone boarding the next car. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced, passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period the benefit of destination control will be limited as passengers have a common destination.",

In some cases the physical length of the antenna can be \"trimmed\" to obtain a pure resistance. On the other hand, the addition of a series inductance or parallel capacitance can be used to cancel a residual capacitative or inductive reactance, respectively.",

By adding an inductance in series with the antenna, a so-called loading coil, the capacitive reactance of this antenna can be cancelled leaving a pure resistance which can then be matched to the transmission line. Sometimes the resulting resonant frequency of such a system (antenna plus matching network) is described using the construct of electrical length and the use of a shorter antenna at a lower frequency than its resonant frequency is termed electrical lengthening.",

Using horizontal polarization, ghosting is reduced because the amount of reflection of electromagnetic waves in the p polarization (horizontal polarization off the side of a building) is generally less than s (vertical, in this case) polarization.

Marconi discovered that by raising the \"aerial\" wire above the ground and connecting the other side of his transmitter to ground, the transmission range was increased. Soon he was able to transmit signals over a hill, a distance of approximately 2.4 kilometres (1.5 mi). In Italian a tent pole is known as l'antenna centrale, and the pole with the wire was simply called l'antenna.
