Sunrise Mill
The Sunrise Mill is an historic grist mill complex that is located near Schwenksville in Upper Frederick Township, Montgomery County, Pennsylvania in the United States. History and architectural features This complex includes a grist mill with an attached saw mill. Built circa 1767, it was enlarged in 1819. The complex also includes a farmhouse that was built circa 1828 and a Swiss bank barn that was erected in 1795. The grist mill originally operated using an internal waterwheel system that ran off the adjacent Swamp Creek, before converting to turbine power after 1870. The property also includes a mill dam that was reconstructed in 1891, a mill race, and a stone arch bridge that was built circa 1845. The property was later owned by Dr. Chevalier Jackson (1865-1958), an internationally known physician and specialist in laryngology, who lived at Sunrise from 1919 until his death in 1958. Dr. Jackson established a workspace inside the grist mill where, using power generated ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Schwenksville, Pennsylvania
Schwenksville is a borough in Montgomery County, Pennsylvania, United States. The population was 1,385 at the 2010 census. It is notable for being located near the site of the Philadelphia Folk Festival. The borough was founded in 1684, when the Lenni-Lenape Indians ceded to William Penn the land along the Perkiomen Creek; it was incorporated in 1903. The borough was named for George Schwenk, whose son, Jacob Schwenk, served in George Washington's army. The town was the inspiration for the protagonist in Catherine Gilbert Murdock's novel ''Dairy Queen'' (2006). The Hall & Oates song "Perkiomen" was written about the Perkiomen Creek, which constitutes Schwenksville's eastern border. "Perkiomen" is Lenape for "muddy waters" and "where the cranberries grow." Schwenksville is also the gateway to the Perkiomen Trail, a nineteen-mile section of the former Reading Railroad's Perkiomen Valley corridor. It now serves as a multi-use rail trail and was completed in 2003. Geography Schwen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chevalier Jackson
Chevalier Quixote Jackson (November 4, 1865 – August 16, 1958) was an American pioneer in laryngology. He is sometimes known as the "father of endoscopy", although Philipp Bozzini (1773–1809) is also often given this sobriquet. Chevalier Q. Jackson extracted over 2000 swallowed foreign bodies from patients. The collection is currently on display at the Mütter Museum in Philadelphia. Biography Jackson was born in Pittsburgh, Pennsylvania. He went to school at the Western University of Pennsylvania (now the University of Pittsburgh) from 1879 to 1883, and received his MD from Jefferson Medical College in Philadelphia. He also studied laryngology in England. His work reduced the risks involved in a tracheotomy. He essentially invented the modern science of endoscopy of the upper airway and esophagus, using hollow tubes with illumination (esophagoscopes and bronchoscopes). He developed methods for removing foreign bodies from the esophagus and the airway with great safety — a h ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Larynx
The larynx (), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus. The word ʻlarynxʼ (plural ʻlaryngesʼ) comes from the Ancient Greek word ''lárunx'' ʻlarynx, gullet, throat.ʼ Structure The triangle-shaped larynx consists largely of cartilages that are attached to one another, and to surrounding structures, by muscles or by fibrous and elastic tissue components. The larynx is lined by a ciliated columnar epithelium except for the vocal folds. The cavity of the larynx extends from its triangle-shaped inlet, to the epiglottis, and to the circular outlet at the ...

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or col ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Laryngology
Laryngology is a branch of medicine that deals with disorders, diseases and injuries of the larynx, colloquially known as the voice box. Laryngologists treat disorders of the larynx, including diseases that affects the voice, swallowing, or upper airway. Common conditions addressed by laryngologists include vocal fold nodules and cysts, laryngeal cancer, spasmodic dysphonia, laryngopharyngeal reflux, papillomas, and voice misuse/abuse/overuse syndromes. Dysphonia/hoarseness; laryngitis (including Reinke's edema, Vocal cord nodules and polyps); *Spasmodic dysphonia; dysphagia; Tracheostomy; Cancer of the larynx; and vocology (the science and practice of voice habilitation) are included in laryngology. Etymology of "laryngology" The word "laryngology" is derived from: * the Greek prefix λαρυγγ- (''laryng-'', root = λάρυγξ, meaning "larynx"), and * the Greek suffix -λογία (''-logy'', root = λόγος, meaning "the study of", or "knowledge").

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor featur ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...
