Halbert Powers Gillette
Halbert Powers Gillette (1869–1958) was an American engineer and prolific author of textbooks and handbooks for the engineering and construction fields. Biography Born on August 5, 1869, in Waverly, Iowa, to Theodore Weld and Laetitia S. (Powers),"GILLETTE, Halbert Powers, Editor, engineer" in: ''WHO WAS WHO IN AMERICA,'' Vol. III 1951–1960 Gillette attended the Hammond Hall Academy in Salt Lake City, from which he graduated in 1886. Six years later in 1892, he received his engineering degree at the School of Mines at Columbia University, where he was classmate of Edward B. Durham.

Halbert P
A halberd (also called halbard, halbert or Swiss voulge) is a two-handed pole weapon that came to prominent use during the 13th, 14th, 15th, and 16th centuries. The word ''halberd'' is cognate with the German word ''Hellebarde'', deriving from Middle High German ''halm'' (handle) and ''barte'' (battleaxe) joined to form ''helmbarte''. Troops that used the weapon were called halberdiers. The halberd consists of an axe blade topped with a spike mounted on a long shaft. It always has a hook or thorn on the back side of the axe blade for grappling mounted combatants. It is very similar to certain forms of the voulge in design and usage. The halberd was usually 1.5 to 1.8 metres (5 to 6 feet) long. The word has also been used to describe a weapon of the Early Bronze Age in Western Europe. This consisted of a blade mounted on a pole at a right angle. History The halberd was inexpensive to produce and very versatile in battle. As the halberd was eventually refined, its point was mor ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Time Sheet, 1909 (front)
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chart Of Total Construction Costs, 1909
A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info. The term "chart" as a graphical representation of data has multiple meanings: * A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data. * Maps that are adorned with extra information (map surround) for a specific purpose are often known as charts, such as a nautical chart or aeronautical chart, typically spread over several map sheets. * Other domain-specific constructs are sometimes called charts, such as the chord chart in music notation or a record chart for album popularity. Charts are often used to ease understanding of large quantities of data and the relationships between parts of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Calculator
A mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or (historically) a simulation such as an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer. Surviving notes from Wilhelm Schickard in 1623 reveal that he designed and had built the earliest of the modern attempts at mechanizing calculation. His machine was composed of two sets of technologies: first an abacus made of Napier's bones, to simplify multiplications and divisions first described six years earlier in 1617, and for the mechanical part, it had a dialed pedometer to perform additions and subtractions. A study of the surviving notes shows a machine that would have jammed after a few entries on the same dial, and that it could be damaged if a carry had to be propagated over a f ...

Mimeograph
A mimeograph machine (often abbreviated to mimeo, sometimes called a stencil duplicator) is a low-cost duplicating machine that works by forcing ink through a stencil onto paper. The process is called mimeography, and a copy made by the process is a mimeograph. Mimeographs, along with spirit duplicators and hectographs, were common technologies for printing small quantities of a document, as in office work, classroom materials, and church bulletins. Early fanzines were printed by mimeograph because the machines and supplies were widely available and inexpensive. Beginning in the late 1960s and continuing into the 1970s, photocopying gradually displaced mimeographs, spirit duplicators, and hectographs. For even smaller quantities, up to about five, a typist would use carbon paper. Origins Use of stencils is an ancient art, butthrough chemistry, papers, and pressestechniques advanced rapidly in the late nineteenth century: Papyrograph A description of the Papyrograph meth ...

Time Clock
A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a device that records start and end times for hourly employees (or those on flexi-time) at a place of business. In mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card. One or more time cards could serve as a timesheet or provide the data to fill one. This allowed a timekeeper to have an official record of the hours an employee worked to calculate the pay owed an employee. The terms Bundy clock, bundy clock, or just bundy''Bundy.'' (n.d.).

Driller (oil)
The Driller is a team leader in charge during the process of well drilling. The term is commonly used in the context of an oil well drilling rig. Driller comes after the Toolpusher in the Rig crew hierarchy. Toolpusher takes the operation orders from the Company-man. Toolpusher then supervises these order to the driller and the rest of the drilling crew and gets the job done. While Toolpusher, driller and the drilling crew generally belong to the Drilling contractor company, Company-man is the employee of the operator company. The driller is in charge of the crew, and running the rig itself. Most of the time, his or her job is simply to monitor the rig's activity, while the automatic driller runs the breaks and drills the hole. The driller is responsible for interpreting the signals the well gives regarding gas and fluids with high pressure. In an emergency he is also responsible for taking the correct counter measures to stop an uncontrolled well control situation from emerging. ...
