Question: 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.

Answer: single-bottom
Question: Geographically, the empire was divided into several provinces, the borders of which changed numerous times during the Umayyad reign. Each province had a governor appointed by the khalifah. The governor was in charge of the religious officials, army leaders, police, and civil administrators in his province. Local expenses were paid for by taxes coming from that province, with the remainder each year being sent to the central government in Damascus. As the central power of the Umayyad rulers waned in the later years of the dynasty, some governors neglected to send the extra tax revenue to Damascus and created great personal fortunes.

Question: Another body established under the Good Friday Agreement, the British–Irish Council, is made up of all of the states and territories of the British Isles. The British–Irish Parliamentary Assembly (Irish: Tionól Pharlaiminteach na Breataine agus na hÉireann) predates the British–Irish Council and was established in 1990. Originally it comprised 25 members of the Oireachtas, the Irish parliament, and 25 members of the parliament of the United Kingdom, with the purpose of building mutual understanding between members of both legislatures. Since then the role and scope of the body has been expanded to include representatives from the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly, the States of Jersey, the States of Guernsey and the High Court of Tynwald (Isle of Man).

Question: There were two distinct lines of Enlightenment thought: the radical enlightenment, inspired by the philosophy of Spinoza, advocating democracy, individual liberty, freedom of expression, and eradication of religious authority; and a second, more moderate variety, supported by René Descartes, John Locke, Christian Wolff, Isaac Newton and others, which sought accommodation between reform and the traditional systems of power and faith. Both lines of thought were opposed by the conservative Counter-Enlightenment.
