Hydrogen tanker. A hydrogen tanker or liquid hydrogen tanker is a tank ship designed for transporting liquefied hydrogen.

Research 
The World Energy Network research program of the Japanese New Sunshine Project was divided into 3 phases during the period 1993 to 2002, its goal was to study the distribution of liquid hydrogen with hydrogen tankers based on the LNG carrier technology of self-supporting tank designs such as the prismatic and spherical tank. Further research on maritime transport of hydrogen was done in the development for safe utilization and infrastructure of hydrogen project (2003–2007).

Similar to an LNG carrier the boil off gas can be used for propulsion of the ship.

Demonstration tests 
The "Suiso Frontier" collected a cargo of liquid hydrogen from the port of Hastings in Victoria, Australia on 28 January 2022 and arrived back in Kobe, Japan at the end of February, 2022 with the cargo.
A second cargo was collected from the Hastings terminal in May, 2022 with a return to Japan in June 2022.

In November 2022, Approval in Principle (AiP) was granted by Nippon Kaiji Kyokai (ClassNK) for Kawasaki Heavy Industries's dual fuel generator engine using hydrogen gas as fuel, which will be installed on a 160,000 m3 liquefied hydrogen carrier developed by Kawasaki. Kawasaki intends to conduct a demonstration test of this engine after installing it on a large-scale liquefied hydrogen carrier which is planned to be commercialized in the mid-2020s.
In June 2023, Kawasaki Heavy Industries announced its completion of technological development for a cargo containment system (CCS) to be used in large liquefied hydrogen carriers.

Matte display. A matte display is an electronic display with a matte surface. Matte displays feature a light-scattering antireflection layer, which reduces reflectivity at the cost of decreased contrast and color intensity under dimly lit conditions. If the steep nanostructures are used – etched in the surface – a matte display can achieve an effect that is similar to continuous refraction index reduction. 

The image quality in displays with matte finish is not as sharp or bright as a glossy screen but is easier to color-match and calibrate with a printer.

EcoJet concept car. The EcoJet concept car is a concept car designed to run on biodiesel fuel, using a Honeywell LTS101 based gas turbine instead of a reciprocating engine. The engine is normally used in helicopters and provides 650 horsepower and 583 ft-lb of torque. Drive is to the rear wheels through a four-speed automatic transaxle adapted from a C5 Corvette. An automatic transmission had to be used, because the turbine requires a constant load and operating a clutch with a manual gearbox would cause the turbine to overspeed.

This concept car was the result of a collaboration between Jay Leno and General Motors, Honeywell, Alcoa and BASF.  Unlike other concept cars, it was meant to be driven on the road in a regular fashion, as well as for show purposes.

It is a two-seater car of a coupé design with a hydroformed aluminum chassis and carbon-fiber-reinforced polymer bodywork. The car contains two separate fuel tanks; one contains the main biodiesel fuel, soybean oil, and the other contains a conventional clean-burning jet engine fuel, Jet A (kerosene). The kerosene is used to start the turbine easily at the beginning of a trip and also to run the engine at the end of a trip to clean it, since biodiesel fuel tends to gum up the fuel system if not cleared. The exhaust gas temperature is 1000 degrees Fahrenheit in normal operation and 1800 Fahrenheit at full power.  Exhaust is directed upward from two ports on the rear deck.  In essence, the car runs on refined cooking oil, thus producing the same kind of smell created by cooking French fries.

The car has an Azentek in-dash car computer running Microsoft Windows Vista, with two LCD screens on the dashboard — one for the aircraft-style digital gauges and another for the multimedia and navigation controls — as well as the standard PC functions, such as word processing and Web access through a WiMAX system. Two other smaller LCD screens are placed on the dashboard to provide rear views, as the car has no rear-view mirrors and uses cameras instead.  The functions are controlled by Touchscreen or by Speech recognition software, using an array of microphones. The car was assembled by the Big Dog crew, mechanics employed by Jay Leno to help him maintain his large collection of cars.

Beam lead technology. Beam lead technology is a method of fabricating a semiconductor device. Its initial application was for high-frequency silicon switching transistors and high-speed integrated circuits. This technology eliminated the labor-intensive wire-bonding process that was commonly used for integrated circuits at the time. It also enabled the automated assembly of semiconductor chips onto larger substrates, facilitating the production of hybrid integrated circuits.

History
In the early 1960s, M.P. Lepselter developed techniques for fabricating a structure that involved electroforming an array of thick, self-supporting gold patterns on a thin film Ti-Pt-Au base, leading to the term "beams." These patterns were deposited on the surface of a silicon wafer. The excess semiconductor material beneath the beams was subsequently removed, resulting in the separation of individual devices and leaving them with self-supporting beam leads or internal chiplets cantilevered beyond the semiconductor material. These contacts not only served as electrical leads but also provided structural support for the devices.

Patents

Patented inventions included:

 Selective Removal of Material Using Cathodic Sputtering (Plasma Etching/RIE), US Patent #3,271,286; issued 1966
 PtSi Semiconductor Contacts and Schottky Diodes (PtSi Schottky Diodes), US Patent #3,274,670; issued 1966

 Vibratory Reed Device (MEMS), US Patent #3,609,593; issued 1971

Legacy

This technology, also known as air-bridge technology, has established itself in high-frequency silicon switching transistors and ultra-high-speed integrated circuits for telecommunications and missile systems. The beam lead devices, produced by the hundreds of millions, became the first example of a commercial microelectromechanical structure (MEMS).

Seismic vibrator. A seismic vibrator is a truck-mounted or buggy-mounted device that is capable of injecting low-frequency vibrations into the earth. It is one of a number of seismic sources used in reflection seismology. The ‘Vibroseis’ exploration technique (performed with vibrators) was developed by the Continental Oil Company (Conoco) during the 1950s and was a trademark until the company's patent lapsed.

Today, seismic vibrators are used to perform about half of all seismic surveys on land.

The largest seismic vibration truck in the world, known as 'Nomad 90’, weighs 41.5T and has a 90,000 lbf force.

Principle

A seismic vibrator transforms the energy provided by a diesel engine into a vibration. It is performed by a shaker, a movable element that generates the vibration thanks to a piston-reaction mass device driven by an electrohydraulic servo valve. The shaker is applied to the ground for each vibration, then raised up so that the seismic vibrator can move to another vibrating point.

Vibrator capability is defined by the maximum force it is capable to generate, called High Peak Force and measured in pound-force. To transmit a maximum force to the ground and prevent the shaker from bumping, part of the weight of the vibrator is applied to the shaker.

The vibration frequency typically ranges between 20–150 Hz.

Popular culture
The plot of Ken Follett's 1998 thriller The Hammer of Eden turns on the use of a stolen seismic vibrator truck by ecoterrorists.

Enforcer (battering ram). Enforcer (also known informally as a "Rammit", "the Sam", "Donker", "Sam", "Bosher", and "the big red key") is the term given to a specially designed manual battering ram manufactured by Sigma Security Devices Ltd and currently used by British police and armed forces, fire services and other agencies to aid in gaining entry to premises.

Construction 
The Enforcer is a 16 kg hardened steel construction with a steel pad at the impact end so that it can absorb the impact, and a handle at the opposite end angled so that the user can swing accurately at inward-opening doors without actually applying their own pressure more than necessary. Further, there is a handle in the middle of the tube aiding the user in handling. The Enforcer can apply more than three tonnes of impact force to door locks. It is 58 cm long.

Police use
In London the Metropolitan Police Services' Armed Response Vehicles and most station vans carry them. Within most forces an officer can only use such a tool once they have attended a course receiving training in the safe handling and operational use. Also, most forces insist that the user wears gloves to cushion the user's hands from the shock created when a door is struck with the ram.

Arthur Francis Turner. Admiral Sir (Arthur) Francis Turner  (23 June 1912 – 26 October 1991) was a British naval officer. He was the son of Rear Admiral AWJ Turner and his wife Mrs AM Turner (née Lochrane).

Naval career
He entered the navy in 1931, completing a four-year course at the Royal Naval Engineering College at Keyham. During the Second World War Turner travelled to Halifax, Nova Scotia, to commission and bring back HMS Newark to the United Kingdom; then spent a period at the RNEC and at HMS Condor (the Royal Naval Air Station at Arbroath), before joining the aircraft carrier  in 1944 as air engineer officer. Indomitable was the carrier squadron flagship in the British Pacific Fleet and Turner's department maintained a very high aircraft serviceability rate for the fleet's strikes. Turner was twice mentioned in despatches, having taken part in air strikes against Okinawa, Japan in 1945.

After the Second World War, Turner planned the Royal Australian Navy's Fleet Air Arm. From 1954 Turner served in the Engineer in Chief's department at Bath, laying the foundation for the Navy's planned maintenance organisation. His other positions included: Captain Superintendent of the Royal Naval Aircraft Yard at Donibristle (1956–58), Director of Aircraft Maintenance and Planning in London, Chief Staff Officer (Technical) on the Central Staff, Mediterranean Fleet (1962–64), Director-General of Aircraft (Navy) at the Ministry of Defence (1964–67) and Chief of Fleet Support at the Ministry of Defence (1967–71). Turner was promoted to Vice-Admiral in June 1968. In 1970, Turner made naval history by becoming the first officer of a non-executive branch to reach the rank of full Admiral. He was one of the Navy's first specialists in naval aeronautical engineering and pioneered the introduction of planned maintenance to improve the reliability of the fleet's machinery. He retired in 1971.

Personal life
In 1963 Turner married Elizabeth Clare de Trafford, daughter of Captain Edmund Hubert de Trafford (a grandson of Sir Humphrey de Trafford, 2nd Baronet) and his wife Hon. Cecilia Strickland (2nd daughter of Baron Gerald Strickland). They raised two sons: Francis (b. 1966) and Michael (b. 1969). The family settled at Effingham, Surrey where Lady Turner lived in retirement until her death on 30 November 2011, aged 79.

Bücker Bü 134. 

The Bücker Bü 134 was a German single engine, high wing cabin monoplane prototype designed and built by Bücker Flugzeugbau GmbH.

History
Two of the designs made by Bücker's Swedish engineer Anders J. Anderson, the Bücker Bü 134, of which only one was built, and a later development, the Bücker Bü 180 Student, could have been the result of the Volksflugzeug proposal made by the LC II, the department of the Technisches Amt of the Nazi Ministry of Aviation responsible for the development of new aircraft, even though the Bü 134 was powered by a Hirth HM 504 A motor which with 105 HP fell a bit beyond the scheme.

Development
In 1936 the Bücker Flugzeugbau company developed their first monoplane design. The Bü 134 was intended as a light general aviation aircraft featuring side by side seating. The wings were foldable for convenient hangarage. Flight testing was not successful and the type was not put into series production. The single prototype aircraft, D-EQPA, was destroyed in a hangar fire on 21 May 1939.

RF microwave CAE CAD. RF microwave CAE CAD is computer-aided design (CAD) using computer technology to aid in the design, modeling, and simulation of an RF (Radio Frequency) or microwave product. It is a visual and symbol-based method of communication whose conventions are particular to RF/microwave engineering.

Scope of design 
RF and microwave circuit design and simulation software for the electronic design automation (EDA) marketplace includes but not limited to circuit simulation, analysis, schematic capture, and integrated design environment for synthesis tools which automate the design of HF (high frequency) circuits from RF to microwave to millimeter waves.  Physical modeling of stripline and microstrip for transmission lines.  A wide range of applications are possible, from analog sub-circuit design to RF circuit design for complex wireless communications systems.

Scope of modeling 
There are a vast number of device or component types which can be simulated in computer aided design software. Generally, the degree of complexity for modeling depends on the software package and the synthesis of off-the-shelf models and application-specific custom models. The component types can be categorized as follows: amplifiers, antennas, attenuators, cabling, capacitors, circulators, combiners, couplers, connectors, DC blocks, delay lines, detectors, diodes, dividers, ferrites, filters, inductors, isolators, limiters, mixers, oscillators, phase shifters, resistors, rotary joints, switches, transistors, terminators, and waveguides.

H&BR Class A. The H&BR Class A (later LNER Class Q10) was an 0-8-0 heavy freight engine designed by Matthew Stirling and built by the Yorkshire Engine Company of Sheffield.  They were the largest of the engines on the Hull and Barnsley Railway.  The Class A was developed to deal with the steeply graded eastern section of the H&BR between Springhead and Sandholme.  Because of this the special link workings they dealt with were nicknamed the "Sandholme Bankers".

Construction
An order for 15 locomotives was placed with the Yorkshire Engine Company in 1907 with 10 arriving in the spring and the remainder in the autumn of that year.  No. 117 was the first to arrive, this engine being the one used to familiarise footplate staff with them.  Due to their size they were affectionately nicknamed "Tinies" by the footplate men.

Operation
The locos were set to work being able to pull 50% more than the previous capabilities of the early Stirling Classes.  Though they were cleared for running on the whole of the H&B mainline, they never strayed from Springhead Shed and were banned from the Denaby, Neptune Street, Cannon Street and Sculcoates lines.  Despite being reasonable locomotives they were regarded with suspicion due to their high boiler pressures following the Wath explosion, so the H&B management increased payment for crews who manned the "Tinies".  The Wath explosion, in 1907, involved H&BR Class F2 0-6-2T number 109.

Modifications
Various modifications were made to the "Tinies" over their lives.  Sanding arrangements were altered to improve the adhesion of the engines, and one engine, No. 129, received a small porthole window in the cabside.  All engines received a cab roof ventilator.  During the First World War, the boiler pressure was dropped from 200 lb/sq.in to 175 lb/sq.in.  No other modifications were made until the merger with the North Eastern Railway.

LNER ownership
Under new management, some "Tinies" were sent to Darlington Works where they received domed boilers.  All members of the class passed into LNER ownership, though by the grouping more powerful ex-Great Central Railway types were available.  Cudworth shed soon became swarmed with ROD 2-8-0s, and 12 of the "Tinies" were away from their home system by 1929.

Withdrawal
The "Tinies" never found favour with other depot footplate staff, and all were withdrawn by the end of 1931.  None were preserved.
