William Henry Bristol
William Henry Bristol (July 5, 1859–June 18, 1930) was an inventor, manufacturer, educator, and environmentalist. Bristol was born in Waterbury, Connecticut. After graduating from the Stevens Institute of Technology in 1884 with an engineering degree, he returned there in 1886 as an instructor and progressed to become a professor of mathematics in 1899. While at Stevens, he patented products including a steel lacing for industrial belts and a pressure chart recorder. The need to manufacture these products led to the founding of the Bristol Company in 1889 with his brother, Franklin, and his father, Benjamin. By 1915, the company was manufacturing the largest and most complete line of industrial instruments in the world, including instruments to measure and record temperature, electricity, pressure, motion, time, flow, and humidity. These instruments were the first to provide an uninterrupted history of manufacturing plant operations; increasing efficiency, improving quality, ...

Gravestone Of William H Bristol And Wife
A headstone, tombstone, or gravestone is a stele or marker, usually stone, that is placed over a grave. It is traditional for burials in the Christian, Jewish, and Muslim religions, among others. In most cases, it has the deceased's name, date of birth, and date of death inscribed on it, along with a personal message, or prayer, but may contain pieces of funerary art, especially details in stone relief. In many parts of Europe, insetting a photograph of the deceased in a frame is very common. Use The stele (plural stelae), as it is called in an archaeological context, is one of the oldest forms of funerary art. Originally, a tombstone was the stone lid of a stone coffin, or the coffin itself, and a gravestone was the stone slab that was laid over a grave. Now, all three terms are also used for markers placed at the head of the grave. Some graves in the 18th century also contained footstones to demarcate the foot end of the grave. This sometimes developed into full kerb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chart Recorder
A chart recorder is an electromechanical device that records an electrical or mechanical input trend onto a piece of paper (the chart). Chart recorders may record several inputs using different color pens and may record onto strip charts or circular charts. Chart recorders may be entirely mechanical with clockwork mechanisms, electro-mechanical with an electrical clockwork mechanism for driving the chart (with mechanical or pressure inputs), or entirely electronic with no mechanical components at all (a virtual chart recorder). Chart recorders are built in three primary formats. Strip chart recorders have a long strip of paper that is ejected out of the recorder. Circular chart recorders have a rotating disc of paper that must be replaced more often, but are more compact and amenable to being enclosed behind glass. Roll chart recorders are similar to strip chart recorders except that the recorded data is stored on a round roll, and the unit is usually fully enclosed. Chart record ...

John Scott Medal
John Scott Award, created in 1816 as the John Scott Legacy Medal and Premium, is presented to men and women whose inventions improved the "comfort, welfare, and happiness of human kind" in a significant way. "...the John Scott Medal Fund, established in 1816...". Since 1919 the Board of Directors of City Trusts of Philadelphia provide this award, recommended by an advisory committee. Eugene Garfield is member of the Advisory Committee. In 1822 the first awards were given to thirteen people by the Philadelphia Society for Promoting Agriculture entrusted by the " Corporation of the city of Philadelphia". The druggist John Scott of Edinburgh organized a $4,000 fund which, after his death in 1815 was administered by a merchant until the first award, a copper medal and "an amount not to exceed twenty dollars", was given in 1822. (At the time, $20 could buy one ox or a 12-volume encyclopedia.) Several hundred recipients have since been selected by the City Council of Philadelphia, whic ...

Pyrometer
A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from the amount of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry. The word pyrometer comes from the Greek word for fire, "πῦρ" (''pyr''), and ''meter'', meaning to measure. The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. Modern pyrometers or infrared thermometers also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux. Principle It is based on the principle that the intensity of light received by the observer depends upon distance of observer from source and temperature of dis ...

19th-century American Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
