D.C. Stover. D.C. Stover (May 9, 1839 – January 17, 1908) was a 19th-century industrialist who was known for founding the Stover Wind Engine Company, the Stover Manufacturing and Engine Company, the Stover Bicycle Manufacturing Company and the Stover Engine Works. He was considered to be one of the wealthiest man in Freeport Illinois.

Early life

He was born in Antrim Township, Pennsylvania May 9, 1839. He was the son of Jacob P. Stover and Elizabeth (née) Emmert Stover. He was the youngest of 12 children and he lived on the family farm in Pennsylvania until he was 18. He moved to California for a time and he worked as a miner. In 1866 he moved to Freeport Illinois. He then worked on inventing farming items, and he invented machines for the manufacture of barbed wire fences. On the 1880 U.S. Census form he listed his occupation as "inventor".

Career 

Throughout his career he established many businesses. In 1876 Stover established the Stover Wind Engine Company to sell Windmills.

In 1881 Stover started a farming machine manufacturing company called the Stover Manufacturing and Engine Company.

In 1889 Stover founded the Stover Bicycle Manufacturing Company to produce bicycles, starting with six employees. The company produced bicycles under the name Phoenix. They were one of the early manufacturers of the Safety bicycle.

By 1897 his bicycle company had become one of the largest bicycle producers, making 20,000 bicycles per year. By 1899 he had sold the company to a Bicycle Trust which organized under the name American Bicycle Company.

Stover then started several other companies in Freeport Illinois. He manufactured combustion engines under the name Stover engine Works. He also operated the Stover Motor Car Company, manufacturing automobiles and marine motors.

During Stover's career his companies produced tanks, bicycles, stationary engines, windmills, cultivators and other farm equipment.

Personal life 
July 13, 1871 he married Mary C. (née) Porter. They had a son and a daughter. He made two trips around the world before his death.

Death 
Stover's cause of death was reported as a severe heart ailment.

IEC metric screw sized connectors. IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread, namely M5, M8 and M12. The number gives their outer screw thread diameter in millimeters as with the identically named screws. However, the connectors are further classified by a so-called coding, denoted by one or more letters, which defines things like pin layout, shape of connecting surfaces and electrical properties.

The many types are partly to prevent incorrect connection. The larger connector sizes are the most varied, with designated connectors ranging from analog and digital signals to AC and DC power.

Each "coding" has a different  keyway that prevents incorrect connection between incompatibly keyed connectors.

The connectors on the ends of cables have a freely rotating screw threads that are turned to screw the plug into its mating socket, while the connectors attached to equipment have fixed screw threads that do not rotate.  This means two panel-mount connectors will not fit together as they cannot be screwed in, however two cables are able to be joined together.  The gender does not affect this arrangement - both male and female panel-mount connectors are fixed, and both male and female cable ends have freely rotating screw threads.

Major uses include factory automation and transportation.
Products can be designed for high weather and chemical resistance (high IP rating) as well as mechanical durability.

Standard listing
 IEC 61076-2-101 M12 connectors with screw-locking: M12 A, B, C, D and P-coding
 IEC 61076-2-104 M8 connectors with screw-locking or snap-locking: M8 A and B-coding
 IEC 61076-2-105 M5 connectors with screw-locking: M5 (only A-coding defined)
 IEC 61076-2-109 M12 connectors with screw-locking for data transmission frequencies up to 500 MHz: M12 X and H-coding
 IEC 61076-2-111 M12 power connectors with screw-locking: M12 E, F, K, L, M, S, T-coding
 IEC 61076-2-113 M12 connectors with screw-locking, power and signal contacts for data transmission frequencies up to 100 MHz: M12 Y-coding
 IEC 61076-2-114 M8 connectors with screw-locking, power and signal contacts for data transmission frequencies up to 100 MHz: M8 D and P-coding
 IEC 61754-27 M12-FO (fiber optic)

Variants

All variants permit one or more pins to be removed to create differently keyed connectors.  For example any pin in a 6-pin connector could be removed, to make six different, incompatible 5-pin connectors.

IGC (file format). An IGC file  (.igc extension) is a text file format used in flight recorders especially in gliders but also in paragliders in order to certify a performance (circuit performed as planned, altitude gain, duration of a flight, etc.). This format allows in particular the recording of the position (determined via the satellite navigation), the recording of the evolution of the altitude (measured by GPS or by barometric sensor) but also of additional information such as the possible ignition of an engine.

Specification for this file format is published by the International Gliding Commission of the International Aeronautical Federation.

These files can be created using specialized equipment called FAI recorder or FAI logger (Volkslogger, LXNAV Nano among others) or using certain anti-collision devices (FLARM) or using a dedicated application that can run on smartphone (XCSoar, LK8000, SeeYou Mobile ...).

IGC files can optionally be digitally signed using public key cryptography, so that an IGC file can be verified as being created on a certain flight computer. IGC files generated on smartphones or other multipurpose hardware will not be signed.

These files can be viewed (GPS track and altitude in particular) using software running in the form of rich client (GPXSee for example ) or web application. Some smartphone applications also allow you to view these files (IGC Viewer & Browser on Android for example).
There are also tools to convert IGC files to tracks in GPX or KML with extension gx:Track format. They allow you to view the track made (but lose a lot of information present in the original IGC file such as the circuit declaration).

Stover Engine Works. Stover Engine Works was a manufacturer of stationary gasoline engines based in Freeport, Illinois. The company was started by D.C. Stover in 1898.

History 

The Stover Engine Works began to create prototype gasoline engines in 1895. The company was formed in 1898. They finalized one of their basic engines in 1904. That version of their engine was in use until the 1920s.

In 1906 the business required a larger building. They built a 3-story building with 21,600. D.C. Stover also worked employed his nephews, Jacob Stover and Frederick Dawson.

The company made engines that could operate on Kerosine. Many were used for pumping or generating power. By 1907 the company was making engines that were as small as 2 horsepower and as high as 50 horsepower in 1907.

The company built a variety of engines including marine motors, and also started the Stover Motor Car Company. He also operated the Stover Motor Car Company for the manufacture of automobiles and marine motors. The engines were known for their simplicity.

By 1914 the company added a 60-horsepower model. The majority of their engines were primarily 1 cylinder, but the 40, 50 and 60 horsepower models were 2 cylinders. One of the best features for consumers was the ability of the engine to work with the less expensive crude oil.

The Stover company and its various company names, made more than 277,000 engines of various sizes and uses.

Joachim Wetzel. Joachim Wetzel (born December 31, 1918, in Aue, Germany) was a German radio engineer and microphone maker.

Wetzel was a trained radio engineer with a master craftsman's certificate. He founded a small workshop in his parents' house in Leipzig in late 1945 when he returned home after a brief war imprisonment period.
At that time, Wetzel was particularly interested in the development and construction of reel tape recorders, condenser microphones and electrostatic tweeters. Later, after the company was running successfully, he opened a larger workshop in 16 Lindenstrasse, Leipzig. This is where the first condenser microphones were produced. He developed his own capsules in the style of Neumann M7, which were also supplied to other microphone manufacturers like Thiele or Adler. From 1960 on, Joachim Wetzel only manufactured microphones in his workshop, although he also provided repair services for other microphone manufacturers, so it is possible to find RFT, ERWA or Neumann microphones that have Joachim Wetzel stickers, meaning they were serviced by him. Over the years he continued to manage his repair workshop, maintaining and servicing microphones, but also TV sets and cassette decks until shortly before his death in May 1989.

Models
Wetzel microphone series - Some microphones were built with different tube body, depending on what was currently available at the time, mixed with self-developed prefabricated plastic parts.

Tube: ECC83

Capsule: Wetzel M7 type capsule

The microphones were built with omnidirectional or cardioid polar patterns. There are also some model with gold plated bodies.

Bayshore Resilience. Bayshore Resilience, also known as Bashor or Bashore Resilience, is a test to determine the ratio of the energy released in deformation recovery to the energy that caused the deformation, or an estimate of the energy-absorbing statistics of a material in reference to another material. A ratio of 100 percent indicates a completely elastic pair of materials where a ratio of 0 percent indicates a pair of completely energy-absorbent materials.

The ratio is determined by dropping a weighted ball onto the material to be measured, and then taking the ratio of the rebound height to the initial height. The ratio is also an indicator of hysteretic energy loss.

The test for Bayshore Resilience is used to test the elasticity of polyurethanes.

Under National Federation of State High School Associations regulations, the material on the edge of a basketball backboard must meet a Bayshore Resilience number of 20 to 30.

J. Hans Meier. Johann Hans Meier (1913 — 2006) was an American engineer who contributed to the development of the strain gauge.

Education 
Meier received a Diplom from the Federal Technical University in Switzerland and move the Massachusetts Institute of Technology in 1937. He obtained an MS working with William M. Murray. Meier continued on with Arthur C. Ruge on work investigating earthquake stress on elevated water tanks. This research led to the invention of the strain gauge concurrent with the work of Edward E. Simmons at the California Institute of Technology. Notably, the Massachusetts Institute of Technology Patent Committee did not feel that the commercial use is likely to be of major importance.

Research and career 

Meier left the Massachusetts Institute of Technology to work for Bucyrus-Erie where he applied strain gauge measurements on the long arms of Bucyrus-Erie's cranes and set up one of the first comprehensive industrial laboratories for experimental stress analysis. He moved to General Electric Company to Manage the Applied Mechanics Section of the General Engineering Laboratory, including work with Dominick J. DeMichele. In 1958 he moved to the IBM Development Laboratory in Vestal, New York until he finally retired in 1980.  He was the President of the Society for Experimental Stress Analysis (SESA) (now Society for Experimental Mechanics) from 1950 to 1951. He was named the fourth Honorary Member of the Society in 1968, a position held until his death in 2006.  When SESA introduced the rank of Fellow, Meier was among the first class of SESA Fellows in 1975 along with the seven other living Honorary Members of the society.
