Catalytic bead sensor. A catalytic bead sensor is a type of sensor that is used for combustible gas detection from the family of gas sensors known as pellistors.

Principle

The catalytic bead sensor consists of two coils of fine platinum wire each embedded in a bead of alumina, connected electrically in a Wheatstone bridge circuit. One of the pellistors is impregnated with a special catalyst which promotes oxidation whilst the other is treated to inhibit oxidation. Current is passed through the coils so that they reach a temperature at which oxidation of a gas readily occurs at the catalysed bead (500-550 °C). Passing combustible gas raises the temperature further which increases the resistance of the platinum coil in the catalysed bead, leading to an imbalance of the bridge. This output change is linear, for most gases, up to and beyond 100% LEL, response time is a few seconds to detect alarm levels (around 20% LEL), at least 12% oxygen by volume is needed for the oxidation.

Issues
Catalyst poisoning - because of the direct contact of the gas with the catalytic surface it may be deactivated in some circumstances. 
Sensor drift - Decreased sensitivity may occur depending on operating and ambient conditions.
Modes of failure - which include poisoning and sinter blockage, they become apparent during routine maintenance checking.

ČSD Class E 669.2. The ČSD E 669.2 is a class of electric locomotives designed, built and used in the former Czechoslovakia for heavy freight trains. The class is a development of the E 669.1 class.

Surviving members of the class are now used in the Czech Republic (ČD Class 182) by ČD Cargo and ODOS, in Slovakia by private operator Lokorail and in Poland by various private operators including CTL Logistics and PTK Holding).

History
As the class is a slight modification of Class E669.1, no prototype was built. The locomotives were built in the years 1963–65 in three types: 59E1, 59E2 and 59E3. 168 locomotives were built in those series.

Currently the whole class is being systematically withdrawn in the Czech Republic, where the last survivors are based in Ostrava. In Slovakia the whole series was withdrawn on 31 March 2006. Since 2005, withdrawn locomotives have usually been rented or sold to various Polish private operators.

Camelion-class sloop. The Camelion class was a class of screw-driven sloops of wood construction, designed by Isaac Watts and operated by the Royal Navy. Eight ships of the class were built from 1858 to 1866 with another eight cancelled. They were initially rated as second-class sloops, but were later reclassified as corvettes.

Design
The class was designed by Issac Watts as second-class sloops of 17 guns, and were a lengthened version of the .

Construction
Built of a traditional wood structure, they were  long at the gundeck,  in beam and displaced 1,365 tons. A barque rig was fitted to allow easy sail handling with a relatively small crew of 180.

Propulsion
They were fitted with a two-cylinder horizontal single-expansion steam engine (although Perseus and Reindeer received single trunk steam engines) driving a single screw. These engines generated 200 nominal horsepower, giving a speed of approximately .

Armament
They were armed with five 40-pounder breech-loading guns and twelve 32-pounder muzzle-loading smoothbore guns, although Reindeer was completed with a single 110-pounder and five 64-pounder guns.

Ships 
The first two vessels were ordered on 3 April 1854, although neither was laid down for several years. Another three were ordered on 1 April 1857 and a further three on 27 March 1858.  The final eight ships were ordered in two batches on 5 March 1860 and 25 March 1861, but were either cancelled, or in the case of Circassian and Trent, completed as ironclad sloops under new names.

Chopper (propeller). A chopper is a propeller design largely of interest for production outboards on fast pad v-bottom boats. Unlike a cleaver the chopper's trailing edge extends aft with a large chord line at each radius. Choppers provide good acceleration and top speed and generally have relatively high rake, which has the effect of increasing the boat's angle of attack without changing the motor trim. This trimming effect is mistakenly called 'bow lift'.

Dead hedge. A dead hedge is a barrier constructed from cut branches, saplings, and foliage. The material can be gathered from activities such as pruning or clearing, and in traditional forms of woodland management, such as coppicing. Its ecological succession can be a beetle bank or hedge.

Restoration ecology and biological pest control 
In coppicing, dead hedges are useful for keeping compartments of a coppice tidy, and keeping the public from certain areas. At the same time, they can provide excellent habitats and corridors for wildlife habitat conservation and restoration ecology. They offer habitats for insects such as beetles, and shelter and feeding opportunities for small mammals and birds. Dead hedges can be used to create habitats for natural 'biological control agents' to provide biological pest control. They have roles in the tending of natural landscapes, wildlife gardening, and organic gardening.

Agriculture
Dead hedges can provide enclosures for livestock. They can also play a role in biological pest control (for example, in organic farming and sustainable agriculture).

Dead hedges provide a carbon-efficient way of recycling biomass, without the need for transport or burning.

John Griffith (engineer). Sir John Purser Griffith (5 October 1848 – 21 October 1938) was a Welsh-born Irish civil engineer and politician.

Griffith was educated at Trinity College Dublin and gained a licence in civil engineering in 1868. He served a two-year apprenticeship under Dr Bindon Blood Stoney, the Engineer in Chief of the Dublin Port and Docks, before working as assistant to the county surveyor of County Antrim. He returned to Dublin in 1871 and worked as Dr. Stoney's assistant, becoming the Chief Engineer in 1898 before retiring in 1913.

He served as president of the Institution of Civil Engineers in Ireland between 1887 and 1889  and of the Institution of Civil Engineers between 1919 and 1920. He was elected Commissioner of Irish Lights in 1913 and was a member of the Royal Commission on Canals and Waterways between 1906 and 1911.

Griffith purchased and drained the bogland at Pollagh, part of the Bog of Allen, a peat fuelled power station was built which drove an excavator, excess peat being taken by the Grand Canal for sale in Dublin. The site was sold to the Turf Development Board in 1936 who used it as a basis for all of their later peat fuelled power stations, the area is now a nature reserve.

Griffith received a knighthood in 1911 and became vice-president of the Royal Dublin Society in 1922. He served as an Honorary Professor of Harbour Engineering at Trinity College, his alma mater, and received an honorary M.A.I. degree from the University of Dublin in 1914. From 1922 he was an elected member of the Seanad Éireann until its abolition in 1936. In the 1930s he and his niece Sarah Purser, endowed the Purser Griffith Travelling Scholarship and the Purser Griffith Prize to the two best-performing students in European Art History at University College Dublin.

He died at Rathmines Castle in Dublin on 21 October 1938.

Millot. Millot was a French automobile built by the Millot brothers in the town of Gray, in 1896.

The car was steered with a flat steering wheel in the center of the car. The seating was a seat at the back facing forward and a seat on the front where the passengers would have been facing in the opposite direction. The engine was under the rear seat and turned the wheels with a huge chain. Another strange feature was the enormous flywheel.

In 1901, the 'Vis-à-vis' body was replaced by a modern 2+2 body. They also built cars with four-cylinder engines.

The automobile was not very successful and the number of cars produced is unknown. It is believed that only a very limited number were ever made. The company was closed in 1902.

Forest Hills Co-op Houses. The Forest Hills Co-operative Houses are located on an  site at 108-03 62nd Drive on the border of the Queens neighborhoods of Forest Hills and Corona in New York City, United States.

History
Unlike the rest of the surrounding neighborhood, the block on which the Houses stand was among the last to be developed because of its soil quality. Initially it was a wetland through which Horse Brook passed on its way from Elmhurst to Flushing Meadows. Near the corner of Colonial Avenue and the future Long Island Expressway, a mill was built in 1652 damming the creek. The block was largely occupied by a reservoir. By the 1930s, surrounding development had dried up the creek and in 1938, the mill was demolished to make way for the Long Island Expressway. Nevertheless, because of the high water table, construction never took place on the block. In the postwar years, the block was used as a golf driving range.

In 1966, Mayor John V. Lindsay announced plans to build three 24-story low-income housing projects on the empty block as part of his scatter-site plan, where low-income projects would be spread out among largely middle-class white neighborhoods. Fearing that Forest Hills would decay into a minority ghetto, the local residents formed the Forest Hills Residents Association to protest the plans.

As a compromise, the height of the towers was reduced to 12 floors, and 40 percent of the residents were to be elderly. Over the years, as the population within the projects aged, it became recognized as a NORC. In addition, the income requirements were higher than for most New York City Housing Authority (NYCHA) housing units. Residents were given "shares" of their units as owners, but they were forbidden from selling them to anyone but NYCHA. The Forest Hills Houses were the first co-operative public low-income housing in the city. On the site of the projects was also the Forest Hills Community House, which has programs for projects residents and neighbors of all ages.

Construction commenced in 1971 amid violent protests. In 1976, the buildings were completed. Until the early 1990s, the projects' population was largely white, elderly and Jewish. Following a 1992 investigation alleging discrimination, the white percentage of the residents has decreased, in favor of more minorities.

Tenants voted in 2017 to convert the public housing project into private rental units and leave NYCHA management. Residents then set up the Forest Hills Mutual Housing Association to manage the property and sold a portion of the site to nonprofit housing developer Phipps Houses for $8.5 million. Phipps will build two buildings, one 17-stories and the other 13-stories which would include community and parking space.

Coiling (pottery). Coiling is a method of creating pottery. It has been used to shape clay into vessels for many thousands of years. It is found across the cultures of the world, including Africa, Greece, China, and Native American cultures of New Mexico. Using the coiling technique, it is possible to build thicker or taller walled vessels, which may not have been possible using earlier methods. The technique permits control of the walls as they are built up and allows building on top of the walls to make the vessel look bigger and bulge outward or narrow inward with less danger of collapsing.  To do this, the potter takes a clay body then rolls it until it forms a coil, or long pliable cylinder. By placing one coil on top of another, different shapes can be formed.  As this is done while the clay is still fresh and soft, individual coils can be joined seamlessly with simple pressure, rather than by scoring and/or applying slip to the surface. Optionally, coils may only be joined internally or externally, leaving them visible on the other side as an aesthetic choice.
