Sentry Siren
Sentry Siren, formerly known as Sterling Siren, is a civil defense siren brand. History Sentry Siren was founded as the Interstate Machine Products Company of Rochester, New York in the very early 20th century. The company would later rename itself to the Sterling Siren and Fire Alarm Company in 1925. The company began producing sirens in 1902, producing small scale vehicular sirens, before beginning large scale siren production with the Model M series of sirens beginning in 1912, designed by Merton C. Armstrong. The Model M was used in fire warning, air-raid warning, and disaster warning and ended production in the 1980s to make way for a new line of sirens. The units were noted for their durability; a 1917 Model M siren is still in use today by the Manchester, Michigan Fire Department. Today, Model M units are considered collectibles by siren enthusiasts, due to rising rarity and simplicity to restore. Some other products that Sterling Siren produced were the "Little Giant", ...

Manufacturing
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final p ...

Civil Defense Siren
A civil defense siren, also known as an air-raid siren or tornado siren, is a siren used to provide an emergency population warning to the general population of approaching danger. It is sometimes sounded again to indicate the danger has passed. Some sirens, especially within small towns, are also used to call the volunteer fire department when needed. Initially designed to warn city dwellers of air raids in World War II, they were later used to warn of nuclear attack and natural destructive weather patterns, such as tornadoes. The generalized nature of sirens led to many of them being replaced with more specific warnings, such as the broadcast-based Emergency Alert System and the Cell Broadcast-based Wireless Emergency Alerts and EU-Alert mobile technologies. A mechanical siren generates sound by spinning a slotted chopper wheel to interrupt a stream of air at a regular rate. Modern sirens can develop a sound level of up to 135 decibels at .

Emergency Population Warning
An emergency population warning is a method whereby local, regional, or national authorities can contact members of the public en masse to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including: * weather emergencies such as tornadoes, hurricanes, and ice storms; * geological disasters such as earthquakes, landslides, volcanic eruptions, and tsunamis; * industrial disasters such as the release of toxic gas or contamination of river water; * radiological disasters such as a nuclear plant disaster; * medical emergencies such as an outbreak of a fast-moving infectious disease; * warfare or acts of terrorism. Many local areas use emergency population warnings to advise of prison escapes, abducted children, emergency telephone number outages, and other events. Requirements In order to develop an effective emergency warning system, certain things are required: * an agreement as to what constitutes an emergency in the area served by ...

Manchester, Michigan
Manchester is a village in Manchester Township within Washtenaw County in the U.S. state of Michigan. The population was 2,037 at the 2020 census. History Chicago Road In 1824 the United States Congress passed the General Survey Act, intended to create and maintain military roads through what was then the west of the country. One third of the funds allocated went to build a road between the strategic army posts of Detroit and Fort Dearborn, at the little town of Chicago. Known as the Chicago Road, it followed the old Sauk Trail and opened the entire area for settlement. Also in 1824, the land around today's Manchester was surveyed by John Mack, who noted it as being "a good mill seat." John Gilbert, who had recently completed work on sections of the Erie Canal, agreed with John Mack, and on May 10, 1826 he purchased of land along the Raisin River at that location. Early village history Originally from upstate New York, John Gilbert resettled to Ypsilanti, Michigan, in 1831. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Box
A call box or callbox is a (usually metal) box containing a special-purpose direct line telephone or other telecommunications device which has been used by various industries and institutions as a way for employees or clients at a remote location to contact a central dispatch office. Uses Police and taxicab dispatching Some taxi companies used callboxes before the introduction of two-way radio dispatching as a way for drivers to report to the dispatch office and receive customer requests for service. Taxi callboxes were installed at taxicab stands, where taxis would queue for trips. Also, before the introduction of two-way radios, some police agencies installed callboxes or "police boxes" at street locations as a way for beat officers to report to their dispatch office. Before the development of emergency telephone numbers and the proliferation of mobile phones, some firefighting agencies installed callboxes at various street locations so that a pedestrian or driver spo ...

Washing Machine
A washing machine (laundry machine, clothes washer, washer, or simply wash) is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid or powder form, to the wash water. History Washing by hand Laundering by hand involves soaking, beating, scrubbing, and rinsing dirty textiles. Before indoor plumbing, individuals also had to carry all the water used for washing, boiling, and rinsing the laundry from a pump, well, or spring. Water for the laundry would be hand carried, heated on a fire for washing, then poured into the tub. That made the warm soapy water precious; it would be reused, first to wash the least soiled clothing, then to wash progressively dirtier laundry. Removal of soap and water from the clothing after washing was a separate process. Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Defense
Civil defense ( en, region=gb, civil defence) or civil protection is an effort to protect the citizens of a state (generally non-combatants) from man-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons. Since the end of the Cold War, the focus of civil defense has largely shifted from responding to military attack to dealing with emergencies and disasters in general. The new concept is characterised by a number of terms, each of which has its own specific shade of meaning, such as ''crisis management'', '' emergency management'', ''emergency preparedness'', ''contingency planning' ...

Siren (noisemaker)
A siren is a loud noise-making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars, and fire engines. There are two general types: mechanical and electronic. Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire sirens are either mounted on the roof of a fire station or on a pole next to the fire station. Fire sirens can also be mounted on or near government buildings, on tall structures such as water towers, as well as in systems where several sirens are distributed around a town for better sound coverage. Most fire sirens are single tone and mechanically driven by electric motors with a rotor attached to the shaft. Some newer sirens are electronically driven speakers.
