In the early days of oilfield operations, there was no way to control the underground pressures encountered during drilling. When an oil or gas reservoir was tapped, wells were allowed to \"blow out\" until pressure was reduced sufficiently to allow capping. Many inventors attempted to develop a device to control such blowouts. In 1922, oil wildcatter James Smither Abercrombie (1891-1975) and machinist Harry S. Cameron (1872-1928) developed a successful ram-type BOP by using a small number of simple, rugged parts. It was installed on the wellhead, and the rams were closed to seal off the well, allowing full control of the pressure during drilling and production. The original design could withstand pressures up to 3,000 psi, an industry record in 1922. (In comparison, today's BOP can withstand 15,000 psi, working in water depth up to 10,000 feet.)\n\u003C/p\u003E","title":"ASME-Landmark:First Ram-Type Blowout Preventer (BOP)","link":"","lat":29.83498,"lon":-95.562748,"icon":"/w/images/a/a0/Orangemarker.png"},{"text":"\u003Cp\u003E\u003Ca href=\"/Milestones:First_Real-Time_Speech_Communication_on_Packet_Networks,_1974_-_1982#_46b5202f5c11e93ab775532f8d64a927\" title=\"Milestones:First Real-Time Speech Communication on Packet Networks, 1974 - 1982\"\u003EMilestones:First Real-Time Speech Communication on Packet Networks, 1974 - 1982\u003C/a\u003E\n\u003C/p\u003E\u003Cp\u003EIn August 1974, the first real-time speech communication over a packet-switched network was demonstrated via ARPANET between MIT Lincoln Laboratory and USC Information Sciences Institute.

Cornish engines do not have rotating parts, such as a flywheel, but rather are controlled by piston movement and the opening and closing of valves. In simple terms, steam depresses the piston and raises the plunger and weight box, and on the return stroke, the plunger descends under gravity, displacing water into the main.

But financial problems plagued the Broad Gauge\u2014and, in 1895, John T.

Prior to the development of this system, automobile wheels had to be removed from the vehicle for static balancing (without rotating). Mr. Merrill came up with the idea of balancing the tire and wheel while they were still mounted on the car. To do this, with the wheel jacked off the ground he would spin the tire and wheel at high speed, and then analyze the resultant vibrations as the wheel coasted to lower speeds. The vibrations were monitored by an electronic pickup, which sat on the floor and was attached to the bumper of the car by a magnet on the end of a probe. The signal was used to trigger a stroboscopic light which made the wheel appear to stand still. This light identified the point at which the balance weight should be added. The signal also helped to establish the amount of weight to be added to effect a proper balance. If the wheel to be balanced were a front wheel, it was spun by a \"spinner\" which consisted of an electric motor with a large flat pulley which was pressed against the wheel. If a rear wheel were to be balanced, only one rear wheel was jacked up and it was spun with the automobile's engine.\n\u003C/p\u003E","title":"ASME-Landmark:Merrill Wheel Balancing System","link":"","lat":39.673634,"lon":-105.010541,"icon":"/w/images/a/a0/Orangemarker.png"},{"text":"\u003Cp\u003E\u003Ca href=\"/ASME-Landmark:Meter-Type_Gas_Odorizer\" title=\"ASME-Landmark:Meter-Type Gas Odorizer\"\u003EASME-Landmark:Meter-Type Gas Odorizer\u003C/a\u003E\n\u003C/p\u003E\u003Cp\u003EThe meter-type gas odorizer was developed in 1937, just a few months after 294 school children and adults died in a natural gas explosion in a New London, Texas, school on March 18, 1937.

Conventional mechanical test systems had been available for years to obtain strength data under long term conditions (hours to days) or static conditions (minutes) using screw or hydraulic loading systems. The maximum deformation or strain rate of these machines is about 0.1 per second (0.1 s-1). Pendulum impact machines can produce strain rates of up to about 100 s-1, yielding only energy absorbed to fracture, but not a complete stress-strain curve. During World War II, strength properties associated with shock waves were developed using light-gas gun or explosively driven flyer-plate impact experiments, producing high hydrostatic pressures and strain rates in excess of 104 s-1. The SwRI Split-Hopkinson Pressure Bar was designed to fill the strain rate range from 102 s-1 to 5.0 x 103 s-1, the time duration of many explosive, ballistic impact, crashes and other accident scenarios of interest for both military and civilian applications.\n\u003C/p\u003E","title":"ASME-Landmark:Split-Hopkinson Pressure Bar Apparatus","link":"","lat":29.449024,"lon":-98.61368,"icon":"/w/images/a/a0/Orangemarker.png"},{"text":"\u003Cp\u003E\u003Ca href=\"/ASME-Landmark:Springfield_Armory\" title=\"ASME-Landmark:Springfield Armory\"\u003EASME-Landmark:Springfield Armory\u003C/a\u003E\n\u003C/p\u003E\u003Cp\u003EGeorge Washington's concern over standardization of rifles for the Continental Army led to the formation of national armory and to his selection of Springfield as its site.

Launched as a state-of-the-art ship for its time, the Mather served as a prototype, incorporating the latest advancements. Subsequent enhancements that extended the ship's economic life included a single oil-fired boiler, steam turbine propulsion, automatic power plant control, as well as a dual propeller bow-thruster. As a result, Great Lakes shipping remained efficient, productive, and competitive with other modes of transportation. The savings helped local iron ore sources maintain an economical edge over non-US suppliers.\n\u003C/p\u003E","title":"ASME-Landmark:Steamboat William G.

In 1849 it became clear that the town was outgrowing the spring capacity, and the Company decided to augment the supply by pumping water from the Codorus Creek. The new building demanded the installation of the latest equipment, a steam-powered pump. When a cleaner water supply was required and the old pumping station was abandoned, the new raw water pumping station was built near Brillhart in\n1897.\n\u003C/p\u003E","title":"ASME-Landmark:Worthington Horizontal Cross-Compound Pumping","link":"","lat":39.962991,"lon":-76.724617,"icon":"/w/images/a/a0/Orangemarker.png"},{"text":"\u003Cp\u003E\u003Ca href=\"/ASME-Landmark:Wright_Field_5-Foot_Wind_Tunnel\" title=\"ASME-Landmark:Wright Field 5-Foot Wind Tunnel\"\u003EASME-Landmark:Wright Field 5-Foot Wind Tunnel\u003C/a\u003E\n\u003C/p\u003E\u003Cp\u003EWind tunnel testing of aircraft models is essential to determine aerodynamic parameters such as lift and drag.
