Geared continuous hinge. A geared continuous hinge is a type of continuous hinge used mostly on doors in high-traffic entrances and features gear teeth that mesh together under a cap that runs the length of the hinge. The hinges use a number of fasteners to attach the door to the frame from top to bottom to distribute a door’s weight more evenly along the frame to stop doors from sagging. They are often used in schools, hospitals, hotels, offices, airports, stadiums, storefronts and many other commercial and industrial buildings.

They are generally made from extruded architectural aluminum and most are anodized to resist corrosion (common colors include black, bronze and clear). To meet building fire codes, they can be made with up to a three-hour fire rating.

Styles
Geared continuous hinges are available in several styles, including concealed, full surface (mortise), half surface (mortise), swing clear and toilet partition models for new construction and retrofit applications.

History
In 1963 Austin Baer, an MIT-trained engineer, earned a patent for his design of hinge leaves with intermeshed gears. In 1968, he earned a second patent for adding thrust bearings to the original design. All geared hinges today are based on this design, which distributes the door’s weight over the entire door length rather than concentrated on two or three spots as with butt or pivot hinges. The gears allowed fluid movement as the door opened and closed.

Baer's patent expired in 1985. He sold his company to a national manufacturer in 1989. With the sale, and with other companies beginning to manufacture geared continuous hinges, the market soon went from regional to national.

Later the hinges were tested to verify their endurance. In 2004, a geared continuous hinge earned 60 minute Ballistic Resistance and Forced Entry certification from the United States Department of State for use in its embassies overseas. In 2005, a geared continuous hinge surpassed 25 million open/close cycles in the ANSI (American National Standards Institute) Physical Endurance Swing Test at Architectural Testing, Inc. in St. Paul, Minn.

Today, every major U.S. commercial hardware manufacturer now offers a line of geared continuous hinges.

Historical Aircraft Restoration Society. The Historical Aircraft Restoration Society, often referred to by its acronym, HARS, is an Australian based aircraft restoration group. The group has two museums, at Shellharbour Airport in New South Wales, Australia, and Parkes, New South Wales, Australia. HARS was formed in 1979 by a group of aviation enthusiasts interested in the preservation of Australian Aviation History. Its mission is "To recover and where possible restore to flying condition, aircraft or types of aircraft that have played a significant part in Australian Aviation History both in the Civil and Military arenas".

The group possesses a collection which includes several large and significant aircraft such as a Boeing 707 and a Boeing 747-400. Many of its aircraft are kept at an airworthy standard, including a Lockheed L-1049 Super Constellation which is the last remaining flying example in the world. Other examples are kept at a taxiable standard where restoration of airframes to an airworthy standard is not feasible. The group operates a Navy Heritage Flight, which operates a range of ex Royal Australian Navy Fleet Air Arm aircraft in support of the Navy.

The group's Boeing 707 was formerly owned by actor John Travolta, who donated the aircraft to the group in 2017. As of May 2022, however, the aircraft is still in the United States, with the COVID-19 pandemic impacting the process to relocate the aircraft to Australia significantly.

The arrival of the 747 required significant preparation to allow the aircraft to land at the small regional Shellharbour Airport without damaging the runway.

Current conveyor. A current conveyor is an abstraction for a three-terminal analogue electronic device. It is a form of electronic amplifier with unity gain. There are three versions of generations of the idealised device, CCI, CCII and CCIII. When configured with other circuit elements, real current conveyors can perform many analogue signal processing functions, in a similar manner to the way op-amps and the ideal concept of the op-amp are used.

History
When Sedra and Smith first introduced the current conveyor in 1968, it was not clear what the benefits of the concept would be. The idea of the op-amp had been well known since the 1940s, and integrated circuit manufacturers were better able to capitalise on this widespread knowledge within the electronics industry. Monolithic current conveyor implementations were not introduced, and the op-amp became widely implemented. Since the early 2000s, implementations of the current conveyor concept, especially within larger VLSI projects such as mobile phones, have proved worthwhile.

Advantages 
Current conveyors can provide better gain-bandwidth products than comparable op-amps, under both small and large signal conditions. In instrumentation amplifiers, their gain does not depend on matching pairs of external components, only on the absolute value of a single circuit element.

First generation (CCI) 
The CCI is a three-terminal device with the terminals designated X, Y, and Z. The potential at X equals whatever voltage is applied to Y. Whatever current flows into Y also flows into X, and is mirrored at Z with a high output impedance, as a variable constant current source. In sub-type CCI+, current into Y produces current into Z; in a CCI-, current into Y results in an equivalent current flowing out of Z.

Second generation (CCII) 
In a more versatile later design, no current flows through terminal Y. The ideal CCII can be seen as an ideal transistor with perfected characteristics. No current flows into the gate or base which is represented by Y. There is no base-emitter or gate-source voltage drop, so the emitter or source voltage (at X) follows the voltage at Y. The gate or base has an infinite input impedance (Y), while the emitter or source has a zero input impedance (X). Any current out of the emitter or source (X) is reflected at the collector or drain (Z) as a current in, but with an infinite output impedance. Because of this reversal of sense between X and Z currents, this ideal bipolar or field-effect transistor represents a CCII−. If current flowing out of X resulted in the same high-impedance current flowing out of Z, it would be a CCII+.

Third generation (CCIII) 
The third configuration of the current conveyor is similar to the CCI except that the current in X is reversed, so in a CCIII whatever current flows into Y also flows out of X.

Velocity V-Twin. The Velocity V-Twin is an American twin engined, homebuilt aircraft, designed by Velocity Aircraft and following the layout of their earlier Velocity XL but with a single vertical tail. It is the flagship model of the Velocity Aircraft Line.

Development

The Velocity V-Twin is a four-seat (with a five-seat option), retractable tricycle landing gear, composite construction aircraft with a twin engine pusher configuration and the canard layout of the Velocity XL single engine aircraft.  Its fuselage is that of the XL-RG, with the addition of the single, vertical surface which replaces the twin end plate fins of the smaller XL.

The aircraft features "gull wing" car-like doors and dual sidestick controllers.  The flight control surfaces are the same as those of the XL. The aircraft's design goal was to offer the safety of twin engines without the stall and spin risks of a conventional twin during single-engine operations. The rear-facing pusher propellers are mounted close together where the fuselage cross-section tapers, reducing asymmetrical single-engine thrust yawing compared to conventional twin-engine aircraft.

The prototype was first flown on 13 March 2012 and appeared at Sun 'n Fun the following month.
