Roslyn, Pennsylvania
Roslyn is an unincorporated community in Abington Township, Montgomery County, Pennsylvania, United States. Originally called Hillside, the name Roslyn came from rose gardens that once grew there. The first known person of European descent to settle the area was John Tyson, who bought a tract of land here in 1717. He built lime kilns to turn the abundant local limestone into quicklime, starting an industry that operated into the late 20th century. The first rail connection to Roslyn was built by the Northeast Pennsylvania Railroad in 1873. Today's railroad station, which replaced the original in the late 1970s, is on SEPTA's Warminster Line The Warminster Line is a route of the SEPTA Regional Rail commuter rail system. It serves stations between its namesake town, Warminster, and Center City, Philadelphia. Half of the route is shared by other lines, including the Lansdale/Doylesto ....

Unincorporated Community
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or uninhabited areas. By country Argentina In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune. Australia Unlike many other countries, Australia has only one level of local government immediately beneath state and territorial governments. A local government area (LGA) often contains several towns and even entire metropolitan areas. Thus, aside from very sparsely populated areas and a few other special cases, almost all of Australia is part of an LGA. Uninc ...

Calcium Oxide
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, Caustic (substance), caustic, alkaline, crystalline solid at room temperature. The broadly used term "''lime (material), lime''" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, ''quicklime'' specifically applies to the single chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime. Quicklime is relatively inexpensive. Both it and a chemical derivative (calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals. Preparation Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wissahickon Creek
Wissahickon Creek is a tributary of the Schuylkill River in Montgomery and Philadelphia Counties, Pennsylvania. Wissahickon Creek rises in Montgomery County, runs approximately 23 miles (37 km) passing through and dividing Northwest Philadelphia before emptying into the Schuylkill River at Philadelphia. Its watershed covers about . Much of the creek now runs through or next to parkland, with the last few miles running through a deep gorge. The beauty of this area attracted the attention of literary personages like Edgar Allan Poe and John Greenleaf Whittier. The gorge area is now part of Wissahickon Valley Park in Philadelphia, and the Wissahickon Valley is known as one of 600 National Natural Landmarks of the United States. The name of the creek comes from the Lenape word wiessahitkonk, for "catfish creek" or "stream of yellowish color". On the earliest map of this region of Pennsylvania, by Thomas Holme, the stream is called ''Whitpaine's creek'', after one of t ...

Sandy Run (Wissahickon Creek)
Sandy Run is a second-order stream (according to the Strahler stream order) that is a tributary to the Wissahickon Creek at Fort Washington State Park. The headwaters are in Dresher and Roslyn, Pennsylvania, and the stream flows west for approximately . The stream follows through Abington, Upper Dublin, Springfield, and Whitemarsh Townships; and flows through several golf courses, including Sandy Run Country Club, Lu Lu Country Club, and Manufacturers Country Club. This creek can be fished in some places, mainly between Manufacturer's Country Club and the Wissahickon Creek. Fish that inhabit this creek include Sunfish, Carp, Smallmouth and Largemouth Bass, Catfish, and several other species.

Parochial School
A parochial school is a private primary or secondary school affiliated with a religious organization, and whose curriculum includes general religious education in addition to secular subjects, such as science, mathematics and language arts. The word ''parochial'' comes from the same root as "parish", and parochial schools were originally the educational wing of the local parish church. Christian parochial schools are called "church schools" or 'Christian schools'. In Ontario, parochial schools are called "separate schools". In addition to schools run by Christian organizations, there are also religious schools affiliated with Jewish, Muslim, and other groups; however, these are not usually called "parochial" because of the term's historical association with Christian parishes. United Kingdom In British education, parish schools from the established church of the relevant constituent country formed the basis of the state-funded education system, and many schools retain a church ...

Northeast Pennsylvania Railroad
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 'points' (and any finer subdivisions are described in fractions of points). Compass points are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal directions are north (N), east (E), s ...

Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, CaCO3 + heat → Calcium oxide, CaO + Carbon dioxide, CO2 This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere (unit), atmosphere), but a temperature around 1000 °C (1832 °F) (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. Early li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
