QUES: 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.
What Elevator Safety Code change required a second dished bulkhead? 

ANS: 1972 ASME A17.1

QUES: Post-punk was an eclectic genre which resulted in a wide variety of musical innovations and helped merge white and black musical styles. Out of the post-punk milieu came the beginnings of various subsequent genres, including new wave, dance-rock, New Pop, industrial music, synthpop, post-hardcore, neo-psychedelia alternative rock and house music. Bands such as Joy Division, Siouxsie and the Banshees, Bauhaus and the Cure played in a darker, more morose style of post-punk that lead to the development of the gothic rock genre.
What style of music did post-punk band the Cure play in?

ANS: darker, more morose

QUES: On 29 October 1956, Israeli forces crossed the Sinai Peninsula, overwhelmed Egyptian army posts, and quickly advanced to their objectives. Two days later, British and French planes bombarded Egyptian airfields in the canal zone. Nasser ordered the military's high command to withdraw the Egyptian Army from Sinai to bolster the canal's defenses. Moreover, he feared that if the armored corps was dispatched to confront the Israeli invading force and the British and French subsequently landed in the canal city of Port Said, Egyptian armor in the Sinai would be cut off from the canal and destroyed by the combined tripartite forces. Amer strongly disagreed, insisting that Egyptian tanks meet the Israelis in battle. The two had a heated exchange on 3 November, and Amer conceded. Nasser also ordered blockage of the canal by sinking or otherwise disabling forty-nine ships at its entrance.
What did the British and French air forces bomb?

ANS: Egyptian airfields in the canal zone

QUES: The Pyx Chamber formed the undercroft of the monks' dormitory. It dates to the late 11th century and was used as a monastic and royal treasury. The outer walls and circular piers are of 11th-century date, several of the capitals were enriched in the 12th century and the stone altar added in the 13th century. The term pyx refers to the boxwood chest in which coins were held and presented to a jury during the Trial of the Pyx, in which newly minted coins were presented to ensure they conformed to the required standards.
What formed the overcroft of the monks' dormitory?
