Volvo B5TL. The Volvo B5TL is a 2-axle low-floor double decker built by Volvo. It replaced the B9TL as Volvo's Euro 6 2-axle double decker product for the UK and Irish markets.

Design
The B5TL is powered by Volvo's new 4-cylinder, 5.1 litre D5K-240 engine, which is rated at 240 bhp/177 kW. The move to a smaller engine is one of the weight-reduction measures implemented to the new bus. Along with its bodybuilding partner Wrightbus, the whole bus achieves a reduction of 1,000 kg comparing to its predecessor. Volvo stated that, with the smaller engine and weight reduction, the B5TL will achieve 10% improvement on fuel economy.

Wrightbus currently offers the lightened Gemini 3 bodywork for the B5TL, which contributes 70% of the weight reduction. MCV is also offering their body as an alternative to the Wrightbus design, while Alexander Dennis have exclusively built 98 examples of their Enviro400 MMC body on the Volvo B5TL chassis for Lothian Buses.

History

The first example appeared in London in autumn 2013, entering service with Go-Ahead London in October 2013 for evaluation. It remained until late February 2014 before being returned to Volvo. This bus was also used by Stagecoach London on other routes.

Four further B5TL demonstrators have appeared in early 2014. One was trialed by Lothian Buses, before moving to Go North East. Another was trialled by operators such as Transdev on service 36. Both of these have now been purchased by East Yorkshire and operate on the company's 66 route between Hessle and Hull. The other two were delivered to London General and Metroline and placed in service on routes 12 and 297 respectively.

In March 2014, Translink of Northern Ireland, placed an order for 42 buses with the new Wright Gemini 3 bodywork, with the last of them carrying the further redesigned version. In May 2014, Lothian Buses had ordered for 25 buses, all of them were Wright Gemini 3 bodied. Translink placed a second order in 2017 for 32 B5TLs, 10 of which being long wheelbase models for use on its Airport 300 service, with the remainder for use in Belfast. All of these have the new style front.

Outside the UK, a B5TL demonstrator was delivered to Dublin Bus in early 2014 for evaluation. A batch of 70 (SG-class) were subsequently ordered by Dublin Bus with deliveries commencing in August 2014. In 2015 Bus Éireann took delivery of 25 B5TLs, while Dublin Bus ordered a further 90 examples. Dublin Bus have continued to place orders, and by the end of 2017 it had a total of 370 in service. Further orders were placed for 2018-2019 deliveries, building up to a total of 546 in service by December 2019. There are also 72 in service with Go-Ahead Ireland, some of which were transferred from Dublin Bus and others delivered brand new to Go-Ahead. By the end of 2017, Bus Éireann had a total of 85 B5TLs in service across Ireland, operating in Dublin, Cork, Limerick, Waterford, Drogheda, Dundalk and Galway.

Volvo Buses removed product information on B5TL from their British website in mid-2021.

Linear heat detection. Linear heat detection (LHD) (also known as linear detection wire or linear heat detection cable or linear heat) is a very commonly used method of fire detection. It can detect a fire anywhere along the length of the cable, and can be of lengths in excess of a kilometer.

Applications can range from building fire alarm systems to mobile plant machinery.

Operation
Linear heat detection (LHD) cable is essentially a two-core cable terminated by an end-of-line resistor (resistance varies with application). The two cores are separated by a polymer plastic, that is designed to melt at a specific temperature (commonly 68 °C for building applications), and without which causes the two cores to short. This can be seen as a change in resistance in the wire.

There are a limited states the LHD cable can be in:

 Open-circuit - effectively an infinite resistance
 Fire detection - resistance of the linear heat cable to the short circuit
 Normal operating condition - apparent resistance will be the same as the end-of-line resistor

Based in Fort Collins, Colorado, it also has employees in Mexico and Brazil. These typically incorporate ABB or FANUC robots with Wolf's own robotic positioners.

Wolf Robotics combines robotic welding with cutting systems used for transportation OEMs and suppliers and heavy fabrication in construction, mining and agriculture.

In August 2015, welding manufacturer Lincoln Electric acquired Rimrock Holdings Corporation and its two divisions, Rimrock Corporation and Wolf Robotics.

Following the acquisition, Wolf Robotics was renamed Lincoln Electric Automation Inc.

History 

Founded in 1944, Wolf Robotics operated under the name Heath Engineering and manufactured farm implement equipment using shape cutting products. In 1976, ESAB purchased Heath Engineering to make it their robotic welding division. ABB bought ESAB in 1993 and designated it as their Welding Systems Division. In 2003, the Rimrock Corporation bought the division and renamed it Wolf Robotics.

Accomplishments 

The company's robotic-grade welding positioners have a load capacity of up to 100,000 kg (220,462 lbs), which are among the strongest in the industry. It introduced robotics to the process of submerged arc welding. As one of the first four companies to be certified by the Robotic Industries Association as a robotic integrator, it is also one of six organizations recognized by the American Welding Society as an approved testing center for the Certified Robotic Arc Welding (CRAW) program.

By 2014, it had installed over 8,400 robotic systems for mining, construction, agriculture, and other industries.

In 2021, Wolf Robotics worked with the United States Army Research Laboratory and BAE Systems to develop an Agile Manufacturing Robotic Welding Cell for aluminum structures that make up the hull of a combat vehicle.

Monolith (catalyst support). Monolithic catalyst supports are extruded structures that are the core of many catalytic converters, most diesel particulate filters, and some catalytic reactors. Most catalytic converters are used for vehicle emissions control. Stationary catalytic converters can reduce air pollution from fossil fuel power stations.

Properties

Monoliths for automotive catalytic converters are made of a ceramic that contains a large proportion of synthetic cordierite, 2MgO•2Al2O3•5SiO2, which has a low coefficient of thermal expansion.

Each monolith contains thousands of parallel channels or holes, which are defined by many thin walls, in a honeycomb structure. The channels can be square, hexagonal, round, or other shapes. The hole density may be from 30 to 200 per cm2, and the separating walls can be 0.05 to 0.3 mm. The many small holes have a much larger surface area than one large hole. High surface area facilitates catalytic reaction or filtration. The open spaces in the cross-sectional area are 72 to 87% of the frontal area, so resistance to the flow of gases through the holes is low, which minimizes energy consumed forcing gases through the structure.

The monolith is a substrate that supports a catalyst. After the monolith is complete, a washcoat is applied that deposits oxides and catalyst(s) (most commonly platinum, palladium, and/or rhodium) on the walls of the holes.

Alternative structures include corrugated metal and a packed bed of coated pellets or other shapes.

Uses
Diesel particulate filters (DPF)
Catalytic incineration
Catalyst support for chemical processes
Vehicle emissions control

Putnisite. Putnisite is a mineral composed of strontium, calcium, chromium, sulfur, carbon, oxygen and hydrogen.  It was discovered on the Polar Bear Peninsula in Shire of Dundas, Western Australia in 2007 during mining activity. Following identification and recognition by the IMA in 2012 the mineral was named after mineralogists Andrew and Christine Putnis.  

Putnisite has unique chemical and structural properties, and does not appear to be related to any of the existing mineralogical families.   Crystals are translucent purple, but show distinct pleochroism (from pale purple to pale bluish grey, depending on the angle of observation) and leave pink streaks when rubbed on a flat surface. 

Putnisite occurs as small (< 0.5 mm) cube-like crystals in volcanic rock.  The mineral formed during the oxidation environment within komatiite to dioritic bodies containing sulfide minerals.

Commonwealth Railways L class. The Commonwealth Railways L class was a class of  freight locomotives built in 1951-1952 by Clyde Engineering, Granville, for the Commonwealth Railways, Australia.

History
In the late 1940s, the Federal Government placed an order with Clyde Engineering, Granville for fifty 2-8-2 locomotives. These were ordered as part of Australia's contribution to the United Nations Relief and Rehabilitation Administration rehabilitation of China. With the first locomotives under construction, China fell to the Communists and Australia's obligations ceased.

The government was able to renegotiate the contract, with only twenty built. Ten were taken by the Commonwealth Railways, even though it already had diesel locomotives on order, with the other ten going to the South Australian Railways as the 740 class. Some were immediately placed on the scrap line at Port Augusta and never entered service. All were officially withdrawn by May 1959. They were scrapped in the mid 1960s with the boilers sold overseas.

Some of the tenders were converted into water carriers for use on the Commonwealth Railways weed killer train, still being in use in the early 1980s.
