Stearns Steam Carriage Company. Stearns Steam Carriage Company was a manufacturer of steam automobiles in Syracuse, New York, founded by Edward C. Stearns.  Stearns built electric automobiles from 1899 to 1900 and steam cars from 1901 to 1903. The company was also known as the Stearns Automobile Company in 1903.

History
E. C. Stearns & Company was a manufacturer of hardware and bicycles and entered the automobile business producing an electric car from 1899 to 1900.  The electric car sold in small quantities until fall 1900 when they decided to switch to steam cars and the Stearns Steam Carriage Company was formed.  George M. Barnes designed the steam car based on his Barnes Steam Trap of 1899.

The Stearns was powered by a compound twin-cylinder 8-hp engine, with a chain drive and tiller steering. It was offered in several body styles, including a station wagon which was probably the first use of that style of car.  The Runabout was priced at $900 () while the top of the line Station Wagon was priced at $1,600, .  By November of 1901, the Stearns Steam Carriage Company reported to have produced over 100 cars.

A Stearns participated in the 1901 500 Mile Endurance Run and received a First Class Ribbon.  Stearns  displayed at the Pan-American Exposition, and exhibited in the major motor shows. In 1902 a Stearns participated in the 500 Mile Boston-New York Reliability Run without any penalized stops.    

Edward Stearns went into business with promoter Edward Joel Pennington and was vice-president of Pennington's Anglo-American Rapid Vehicle Company.  A new incorporation called the Stearns Automobile Company became a subsidiary, but in the summer of 1903 the property of the Stearns Automobile Company was sold at a receiver's sale for $595.

Mouseless. The Mouseless is a proposed input device for personal computers. A prototype Mouseless, designed by Pranav Mistry of the MIT Media Lab. Mouseless replaces conventional hardware mouse with a set of infrared laser strobe, an infrared camera and image recognition software. The laser beam is optically split into a wide beam illuminating an imaginary plane above the working desk. The camera captures the pattern of invisible infrared light as it illuminates user's hand. The user rests the palm on the desk and commands the system in the same way as he or she would do with a conventional mouse.

As of July 2010, the project has been presented to the media but has not been commercialized. According to Mistry' statement, the fully functional prototype of the Mouseless costs around $20.

Lawrence Ennis. Lawrence Ennis CMG OBE (31 August 1871 – 5 May 1938) was a Scottish engineer.

He was best known as the managing director of Dorman Long and the main supervisor of the construction of the Sydney Harbour Bridge.

Life
Ennis was born in West Calder, Scotland. He was descended from a family of engineers on his maternal line. His father was a builder from County Meath in Ireland. He was educated at Gavieside School, but due to his family's poor circumstances he left at the age of 12. His first job was to work as a drawer in a local shale pit. He emigrated with his family to Rochester in the United States at the age of 15. He attended a technical college in Rochester and was apprenticed to an engineering firm.

Ennis developed his reputation when he patented a new angle iron whilst employed at the Carnegie steel works in Pittsburgh. Ennis managed one of the American Bridge Company's largest sites by 1900. Ennis joined Dorman Long in 1903 as superintendent in charge of bridge and constructional works. In 1905 he was made works manager. Ennis became general manager of the company in 1915 and a company director in 1924.

Ennis was appointed OBE in 1918, in recognition of his conversion of the Dorman Long works into a munitions manufacturing site during World War One.

From 1924 to 1932 Ennis was resident in Australia to manage the construction of Sydney Harbour Bridge.

Upon his return to Britain in 1932, Ennis was appointed managing director of Dorman Long. Under his tenure the firm built a large steelworks at Warrenby, Redcar.

He died in 1938.

Rampart Engineering. The Rampart Engineering Company was a British manufacturer of fire extinguishers founded in 1910.

Company timeline

1910 Rampart Engineering Company was formed in 1910 by Leonard Jones to make fire extinguishers for the trade. Their first factory was in Walworth Road, London. Leonard Jones was the grandson of Samuel Jones, the founder of Samuel Jones and Co. Ltd. the famous paper converters and finishers.
1912 Rampart moved to Peckham Grove, London and became the engineering department of Samuel Jones and Co. Ltd., making tape-dispensing machines as well as fire extinguishers.
1918 Rampart took over a new factory in Peckham Grove and expanded throughout the first World War and after, continuing to make extinguishers for the trade, its customers including Pyrene and Minimax. Read and Campbell's famous copper-shell hand-rivetted extinguisher was also made by Rampart.
1926 Production of extinguishers had expanded to one thousand per week.
1929 Rampart changed its name to Samuel Jones and Co. (Engineering) Ltd., but for many years after was known by the locals as 'down the Rampart'. In the period between the wars the company became the largest manufacturer to the fire trade in the UK, producing an extremely wide range of extinguishers, hose reels, and trolley and trailer units.
1937 A new factory was built at Peckham Grove.
1939-45 During the second World War one million extinguishers, four hundred thousand sten guns and vast quantities of other military equipment were produced as part of the war effort.
1968 Chubb and Sons Ltd. purchased Samuel Jones (Engineering) Ltd., and in 1973 the name reverted to the original Rampart Engineering Co. Ltd. In 1971 Rampart purchased Fireward Ltd., specialist manufacturers of plastic bodied fire extinguishers.
1981 Rampart was still operating from Peckham Grove manufacturing for the trade.

Caustic embrittlement. Caustic embrittlement is the phenomenon in which the material of a boiler becomes brittle due to the accumulation of caustic substances.

Cause

As water evaporates in the boiler, the concentration of sodium carbonate increases in the boiler. In high pressure boilers, sodium carbonate is used in softening of water by lime soda process, due to this some sodium carbonate maybe left behind in the water. As the concentration of sodium carbonate increases, it undergoes hydrolysis to form sodium hydroxide.

The presence of sodium hydroxide makes the water alkaline in nature. This alkaline water enters minute cracks present in the inner walls of the boiler by capillary action. Inside the cracks, the water evaporates and the amount of hydroxide keeps increasing progressively. The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes embrittlement of boiler parts like rivets, bends and joints, which are under stress.

Prevention

This can be prevented by using sodium phosphate () instead of sodium carbonate as softening reagents. What happens is that its molecules will get inside the hair-line crack and block it, as a result of which sodium hydroxide, even if it is there, will not be able to come in contact with iron, and no reaction will be there. Adding tannin or lignin to boiler water blocks the hair-line cracks and prevents infiltration of NaOH into these areas. Adding Na2SO4 to boiler water also blocks the hair-line cracks.

Zenair CH 150. The Zenith CH 150 Acro Zenith is a Canadian single-engine, low wing, all-aluminum aircraft designed by Chris Heintz and produced by Zenair in kit form for amateur construction. The aircraft is intended for aerobatic use and was introduced at the Experimental Aircraft Association convention in 1980.

The CH 150 is one of only six amateur-built aircraft types specifically approved by Transport Canada for aerobatics, without other restrictions.

Development
After emigrating to Canada and setting up Zenair to sell plans and kits for amateur construction of his Zenith two seat-light aircraft, the German aircraft designer Chris Heintz started design of a smaller, single seat development of the Zenith, the Zenair CH 100 Mono-Zenith. The first CH 100 made its maiden flight on 8 May 1975, powered by a 55 hp (41 kW) Volkswagen air-cooled engine of 1600 cc. Heintz used the Mono-Zenith as a starting point to develop a single-seat aircraft for aerobatic training and competition flying, the resulting aircraft, the CH 150 Acro-Zenith making its maiden flight on 19 May 1980. It was designed to be powered by engines of between 100 and 180 hp (75–134 kW) and had a tailwheel undercarriage instead of the nosewheel undercarriage of the earlier aircraft. Zenair continued to produce kits until 1988.

In a 1983 advertisement Zenair described the design goals of the CH150:

Orionette. Orionette is a historic German motorcycle brand.

The Orionette AG für Motorfahrzeuge (also: Orion AG für Motorfahrzeuge) was a German motorcycle manufacturer. The company was founded in 1921. The company's headquarters was the Industriehof Oranienstraße 6 in Berlin-Kreuzberg. There was also the serial production of the Orionette. It was one of the most important companies in the automotive and motorcycle industry in Berlin.

The company built a range of , ,  and  two-stroke machines with mainly unitdesign engines and two or three-speed gearboxes. The design department, headed by Engelbert Zaschka, also produced some interesting unorthodox designs. Unfortunately the very desmodromic lay-out of this interesting two-stroke engine still remains secret. It is called system Zaschka.

At last later sales declined and in 1925 the company went bankrupt and closed.
