H. C. Patten. Henry C. Patten (1887 – January 30, 1956) was General Manager of the Toronto Transportation Commission from 1939 until 1952.

He was born in Boston, Massachusetts, and graduated from the Massachusetts Institute of Technology in 1908 with a degree in electrical engineering. He served in the U.S. Army Engineering Corps for two years during World War I, and was otherwise employed by the consulting engineering firm of Jackson and Moreland, working on projects involving railways and other utilities.

He came to Toronto in 1920 as a resident engineer with Jackson and Moreland, who had been engaged by the City of Toronto government to assist with the arbitration and valuation of the City's purchase of the property of the Toronto Railway Company. In November 1923, he left the engineering firm to join the Toronto Transportation Commission as a Cost Engineer. In May 1924 he was appointed Comptroller.

He was appointed General Manager effective January 1, 1939, following the death in December 1938 of D.W. Harvey. He served as General Manager until 1952.

Mr. Patten also served as President of the Canadian Transit Association, director of the American Transit Association and director of the Toronto Industrial Commission. Patten died in Toronto in 1956.

The revenue building at the TTC's Hillcrest Complex is named the Patten Building in his honour.

Bis(2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl)oxalate. Bis[2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl]oxalate (also known as bis(2,4,5-trichloro-6-carbopentoxyphenyl) oxalate or CPPO) is an organic compound with the formula .  A white solid, it is classified as a diester of oxalic acid.  It is an active ingredient  for the chemiluminescence in glowsticks. It can be synthesized by reacting 2-carbopentoxy-3,5,6-trichlorophenol with oxalyl chloride. 

When mixed with hydrogen peroxide in an organic solvent (diethyl phthalate, ethyl acetate, etc...) in the presence of a fluorescent dye CPPO causes the emission of light, following its degradation to 1,2-dioxetanedione (note that many side-groups of the aromatic rings are not shown.):

The reaction rate is pH dependent, and slightly alkaline conditions achieved by adding a weak base, e.g. sodium salicylate, will produce brighter light.  Developed by American Cyanamid in the 1960s, the formulation containing CPPO, a fluorescer, and a glass capsule containing hydrogen peroxide and a base catalyst, all in dialkyl phthalate solvents, was marketed as Cyalume.

The following colors can be produced by using different dyes:

Beta Code. Beta Code was a method of representing, using only ASCII characters, the characters, accents, and formatting found in ancient Greek texts (and other ancient languages). Its aim was to be not merely a romanization of the Greek alphabet, but to represent faithfully a wide variety of source texts – including formatting as well as rare or idiosyncratic characters. For most applications, it has been obsoleted by Unicode.

Beta Code was developed by David W. Packard in the late 1970s and adopted by Thesaurus Linguae Graecae in 1981. It became the standard for encoding polytonic Greek and was also used by a number of other projects such as the Perseus Project, the Packard Humanities Institute, the Duke collection of Documentary Papyri, and the Greek Epigraphy Project at Cornell and Ohio State University. Beta Code can be easily converted to a variety of systems for display, most notably Unicode. Most of these projects have since converted their data to Unicode. For example, Perseus originally encoded all its Ancient Greek texts using Beta code, but now releases them as Unicode.

Encoding

Greek alphabet

Notes 

 Instead of upper-case Latin letters, lower-case Latin letters may also be used (e.g. a for α and *a for Α).
 The TLG Beta Code Manual uses upper-case ASCII letters to represent Greek letters. A variant (used by the Perseus Project) uses lower-case ASCII letters instead. In both cases, the unadorned ASCII letter represents a lower-case Greek letter, and an asterisk must be added to indicate an upper-case Greek letter.
In general, one encoding character S for Greek sigma is sufficient; it is interpreted as a final sigma at the end of words or when followed by punctuation, and as a medial sigma in other positions. In cases where this auto-disambiguation is not correct, the specific codes S1 and S2 are available.
 Some representations use J for the final sigma and S for the medial sigma. However, J is not supported/output by many applications such as Morpheus and uni2beta.

Punctuation 

The character ' is used both for encoding an apostrophe and for adding a metrical breve to a vowel. The intention is disambiguated because the apostrophe is used in Greek only for elision, which normally occurs after a consonant.

Accents and diacritics 

These are normally postfix operators, as in the examples above, but for capitalized words, accents come between the * and the letter. The documentation does not otherwise define a required or canonical order for accents. In some data sources, breathing is normally seen before a tonal accent, and one implementation defines a canonical order of breathing, accent, iota subscript. In some implementations, the ordering of the accents can determine the arrangement of the combining characters after conversion to Unicode. Many implementations do not implement macronization.

Institute of Transportation Engineers. The Institute of Transportation Engineers (ITE) is an international educational and scientific association of transportation professionals who are responsible for meeting mobility and safety needs. ITE facilitates the application of technology and scientific principles to research, planning, functional design, implementation, operation, policy development, and management for any mode of ground transportation.

History
The organization was formed in October 1930 amid growing public demand for experts to alleviate traffic congestion and the frequency of crashes that came from the rapid development of automotive transportation. Various national and regional conferences called for discussions of traffic problems. These discussions led to a group of transportation engineers starting the creation of the first professional traffic society. A meeting took place in Pittsburgh on October 2, 1930, where a tentative draft of the organization's constitution and by-laws came to fruition. The constitution and by-laws were later adopted at a meeting in New York on January 20, 1931. The first chapter of the Institute of Traffic Engineers was established consisting of 30 men with Ernest P. Goodrich as its first president.

The organization consists of 10 districts, 62 sections, and 30 chapters from various parts of the world.

Transportation Professional Certification Board
ITE founded the Transportation Professional Certification Board Inc. (TPCB) in 1996 as an autonomous certification body. TPCB facilitates multiple testing and certification pathways for transportation professionals.

Standards development
ITE is also a standards development organization designated by the United States Department of Transportation (USDOT). One of the current standardization efforts is the advanced transportation controller. ITE is also known for publishing articles about trip generation, parking generation, parking demand, and various transportation-related material through ITE Journal, a monthly publication.

Criticism
Urbanists such as Jeff Speck have criticized ITE standards for encouraging towns to build more, wider streets making pedestrians less safe and cities less walkable. Donald Shoup in his book The High Cost of Free Parking argues that the ITE Trip Generation Manual estimates give towns the false confidence to regulate minimum parking requirements which reinforce sprawl.

Mathers Bridge. Mathers Bridge is a  low-level swing bridge located on the southern tip of Merritt Island, Florida, crossing the Banana River at the end of County Road 3.

History
The bridge was built in 1927 by John Mathers in order to connect Merritt Island to what is now Indian Harbour Beach, and was moved to its present location in 1952. It was constructed by the Austin Brothers Bridge Company. The bridge and the control house were rehabilitated in 2007. During the summer of 2022, the bridge was closed for repair due to corrosion. As of March 2023, the bridge is fully functional, allowing many boats to pass via its swinging mechanism each day.

Takanami-class destroyer. The  is a class of destroyer serving with the Japan Maritime Self-Defense Force (JMSDF). This warship is the slightly modified class of second-generation, general-purpose destroyers of the JMSDF.

Background
Since FY1991, the JMSDF started construction of the second-generation, , . These destroyers are generally satisfactory for the fleet, but there is some discontent. From FY1998 onwards, a slightly modified version that corrected these dissatisfaction points was to be built: Takanami class.

Design
The hull design is generally based on that of the Murasame class. However, the weapons mounted are different, and as a result, the internal structure has also been changed. The large lattice mast affected the stealthiness of the Murasame class, so in Takanami class, it was planned to change to two small masts, but that was not implemented.

Although their displacement become slightly increased, there was no change to their main engines, as it was not a big difference so it had little effect on the performance of the ship.

Equipment
The combat system was slightly improved. The combat direction system is similar to the Murasame class in the first three ships, but in the fourth ship, workstations were changed to AN/UYQ-70, and in the fifth ship, it corresponded to the communication in Link 16. Radars are the same as those of Murasame class, sonars are also small revision type.

In terms of weaponry, instead of the 3-inch gun that has been adopted by conventional destroyers, a larger Oto Melara 127 mm gun was introduced. Although vertical launching systems were divided into two places in the Murasame class, 16-cell Mk 41 for VL-ASROC on the bow deck and 16-cell Mk 48 for Sea Sparrow (later replaced with Evolved Sea Sparrow) on the middle deck, they are compiled in one place, 32-cell Mk 41 on the bow deck in this class.

Power hammer. Power hammers are mechanical forging hammers that use an electrical power source or steam to raise the hammer preparatory to striking, and accelerate it onto the work being hammered. They are also called open die power forging hammers.  They have been used by blacksmiths, bladesmiths, metalworkers, and manufacturers since the late 1880s, having replaced trip hammers.

Design and operation

A typical power hammer consists of a frame, an anvil, and a reciprocating ram holding a hammer head or die. The workpiece is placed on the lower anvil or die and the head or upper die strikes the workpiece. The power hammer is a direct descendant of the trip hammer, differing in that the power hammer stores potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, and by the fact that it accelerates the ram on the downward stroke. This provides more force than simply allowing the weight to fall. Predecessors like trip hammers, steam drop hammers, board or strap hammers, used the power source to raise the ram or hammer head, but let it fall solely under gravity.

Power hammers are rated by weight of moving parts that act directly on the work piece. This includes the weight of the parts that may consist of upper die, ram, mechanical linkage arms and spring(s) or ram, piston, and associated connecting rod(s).  Specific design elements are dictated by the power source.  The largest power hammer was powered by steam and was rated at .

Types
Power hammers are generally categorized by their power source.

Steam

Steam hammers use steam to drive the hammer. These tended to be the largest models as the great energy of steam was needed to operate them.  A locomotive works was one location where such large hammers were needed and the workpieces were sometimes so large it required an overhead crane and several men to position the piece in the hammer, and a man to operate the machine.

Mechanical

These hammers tended to be smaller and were operated by a single man both holding the workpiece and operating the machine. The majority of these mechanical linkage machines were powered by line shaft flat belt systems or later electric motors that rotated a crank on the machine that drove the ram.

Air 
Air-power hammers use pneumatics to drive the hammer.

History
Steam and mechanical power hammers were made into the middle of the 20th century in the United States. At the end of the 19th century the mechanical power hammer became popular in smaller blacksmith and repair shops. These machines were typically rated between  of falling weight. Many may still be seen in use in small manufacturing and artist-blacksmith shops today. In the middle of the 20th century power hammers driven by compressed air began to gain popularity and several manufacturers are currently producing these hammers today.

Kenji Urada. Kenji Urada (c. 1944 – July 4, 1981) was a Japanese factory worker who was killed by a robot. Urada is often incorrectly reported to be the first person killed by a robot, but Robert Williams, a worker at the Ford Motor Company's Michigan Casting Center, had been killed by a robot over two years earlier, on January 25, 1979.

Urada was a maintenance worker at the Kawasaki Heavy Industries plant in Akashi. He died while checking a malfunctioning robot; after jumping over a safety barrier, which was designed to shut down power to the machine when open, he apparently started the robot inadvertently. The robot, built by Kawasaki under a license from Unimation, pinned him against an adjacent machine and either crushed him or stabbed him in the back. Other workers in the factory were unable to stop the machine as they were unfamiliar with its operation.

International newswire service UPI reported Urada was the first human killed by a robot on December 8, 1981. The circumstances of his death were not made public until after an investigation by the Hyōgo labor standards bureau was completed. The investigation concluded that workers were not sufficiently familiar with the machines and the machines were not sufficiently regulated. The robot that killed Urada was removed from the Akashi plant, and man-high fences were erected around the other two robots in the plant in the wake of the accident.
