Synergy Aircraft Synergy. The Synergy Aircraft Synergy is a proposed five-seat, single-engine, kit aircraft, designed by John McGinnis of Kalispell, Montana and intended for production by his company, Synergy Aircraft.

The aircraft's closed wing design, termed a "double box tail", is intended to lower induced drag and be stall resistant, along with boundary layer control methods. Many of the details are disclosed in .

Design and development
Development was started in 2010 to develop the Synergy as a future kit airplane. The Synergy is the first aircraft that was designed to use the  DeltaHawk V-4 engine. An electric-powered 1/4 scale version of the aircraft has been built and flown via radio control.

The Synergy design was unveiled at the 2011 CAFE Foundation electric aircraft symposium. The aircraft was intended to compete in the 2011 NASA/CAFE Green Flight Challenge, but its funding and engine were delayed, forcing the team to withdraw from the competition.

After receiving the DeltaHawk engine in December 2011 work resumed and a funding drive was launched to complete the prototype. Intended as a Kickstarter crowdfunding project, the initial project application and appeal were rejected on the basis of not fitting in with Kickstarter's creative arts focus. On 13 May 2012, however, Kickstarter informed McGinnis that they had reconsidered and that the project was approved. The project raised US$ 95,627 gross funds.

By mid-December 2012 McGinnis indicated that the Kickstarter campaign had raised US$80,000 and that he was intending to have a flying proof-of-concept aircraft at AirVenture 2013. He also stated that if the aircraft is not complete then he will not have a display there. The Kickstarter campaign also attracted a lot of interest, but answering email and phones calls has slowed work on the prototype down.

In May 2023 DBT Aero co-founder McGinnis was let go and replaced by Thomas Hatfield as CTO.

In July 2023 the first full scale prototype received its FAA Special Airworthiness Certificate in the experimental category which allowed to conduct flight tests.

Charles Redvers Westlake. Sir Charles Redvers Westlake (29 April 1900 – 17 February 1972) was a British electrical engineer and industrialist.

Biography 
Westlake was born in the hamlet of Forton in Hampshire on 29 April 1900, to Colour Sergeant Harry Westlake and his wife Elizabeth.

In 1929 Westlake became County Electrical Engineer for Dumfriesshire, and two years later Chief Engineer and Manager of the Electricity Board for Northern Ireland.
From 1935 to 1948, he was an engineer at the electricity generating station (established by the Finchley Electric Light Co. and subsequently acquired by Finchley Urban District Council) at Squires Lane in Finchley, North London.
During World War II he served at the War Office, and at the same time was president of the Finchley branch of the NALGO trade union.

In 1946 Westlake was appointed by the British Colonial Office to recommend a site for a hydroelectric power station in Uganda. His report, jointly produced in 1947 with the civil engineer E. V. Richards, recommended Owen Falls as the location. Westlake, as chairman of the newly formed Uganda Electricity Board, went on to direct the project (now known as the Nalubaale Hydroelectric Power Station) until its commissioning in 1954. Queen Elizabeth attended the opening of the dam and conferred a knighthood on Westlake. In 1955 he was reported as being President of the East African Association of Engineers.

Westlake retired from his post in Uganda in October 1955. In 1956 he returned to England to become chairman of Metal Industries, Limited, where he remained until 31 October 1964, leading the group from a position of heavy losses to a profitable state. He went on to become chairman of the metal window manufacturer Williams and Williams.
In 1969 he became chairman of the S. W. Wood Group, a non-ferrous metal merchant

Westlake married twice: in 1929 to Winifred Lucy Luxton Western, with whom he had two daughters (Patricia and Barbara), and in 1968 to Evelyn Isabel Aistrup. He died in Lisbon in 1972 of prostate cancer.

Gooseville Mill/Grist Mill. The Gooseville Mill/Grist Mill is a historic mill on the North Branch Milwaukee River in Gooseville, Wisconsin. The mill was built in 1879 to replace an 1855 mill that had burned down. The mill is a small custom mill with board and batten siding and is typical of the custom mills common in Sheboygan County in the 1800s. A Lefel turbine powered the mill, replacing the paddle wheel used in the 1855 mill. A burr mill was used to grind the grain processed at the mill. As of 1984, the mill was still operational and occasionally used as a sawmill.

The mill was added to the National Register of Historic Places in 1984.

Software bus. A software bus is a software architecture model where a shared communication channel facilitates connections and communication between software modules. This makes software buses conceptually similar to the bus term used in computer hardware for interconnecting pathways.

In the early microcomputer era of the 1970s, Digital Research's operating system CP/M was often described as a software bus. Lifeboat Associates, an early distributor of CP/M and later of MS-DOS software, had a whole product line named Software Bus. D-Bus is used in many modern desktop environments to allow multiple processes to communicate with one another.

Examples 
 Lifeboat Associates Software Bus-80 aka SB-80, a version of CP/M-80 for 8080/Z80 8-bit computers
 Lifeboat Associates Software Bus-86 aka SB-86, a version of MS-DOS for x86 16-bit computers.
 Component Object Model for in-process and interprocess communication.
 D-Bus for interprocess communication.

L&YR Class 3. The L&YR Class 3 was a class of  steam locomotives of the Lancashire and Yorkshire Railway introduced in 1891 with forty being built.  George Hughes rebuilt six locomotives with superheaters between 1908 and 1909, they were later designated L&YR Class 4.  All passed to the London, Midland and Scottish Railway at the grouping in 1923 but were withdrawn by 1930.

Design

Origins
The design originated with a William Barton Wright's 4-4-0 of 1880 with driving wheels of  and boiler pressure of .  Aspinall then produced a modified version with 6ft wheels which was the basis for the class 3.

Class 3
John Aspinall succeeded Barton Wright in 1886.  He initially order more locomotives of Barton's Wright's  design. but determined a driving wheels of  and boiler pressure increased to  should give increased speed for the same tractive effort.

Class 4
Six locomotives were rebuilt with superheaters by George Hughes between 1908 and 1909.  They became L&YR Class 4 in the Hughes classification scheme introduced in 1919.  All six passed to the London, Midland and Scottish Railway at the grouping in 1923.

There were two different versions of the rebuild. One had 19" bore cylinders and Joy valve gear. The other had 20" bore cylinders and Walschaerts valve gear.

Numbering
The L&YR numbered them 1093-1229 and then randomly, using numbers between 318 and 498. The LMS numbered its 34 Class 3 locomotives 10150-10183. The six which had been rebuilt to Class 4 were numbered in a separate series, LMS 10190-10195.

Class 4 numbering

Withdrawal
Withdrawals began in 1925 and the Class 4 superheated locomotives were all withdrawn by 1926.  The last members of the type were withdrawn in 1930.  None have been preserved.
