Porterfield Aircraft Corporation. The Porterfield Aircraft Corporation was an American aircraft design and manufacturing company founded in 1934 in Kansas by Edward E. Porterfield.

History

Edward Porterfield was running a flying school at the Fairfax Airport outside Kansas City. He had been operating Jennies and Lincoln Standard biplane trainers, and felt the need for a more suitable and better-performing trainer aircraft. He consulted with several aeronautical engineers of the period, including Giuseppe Mario Bellanca, and soon launched the production of several light single-engine two-seat high-wing and biplane aircraft. Then, in 1925, he started the American Eagle Aircraft Corporation.

Late in 1929, the worldwide stock market crash severely depressed the sale of non-essential items such as sport airplanes, although American Eagle continued producing airplanes until 1931. Early in that year, Porterfield's company declared bankruptcy and halted production. On 15 May 1931, the company's assets were purchased by the Lincoln-Page Aircraft Company of Lincoln, Nebraska, and Porterfield assumed the title of aircraft sales representative of that company, which became known as the American Eagle-Lincoln Aircraft Corporation, with production headquarters in Lincoln.

Porterfield left the company in 1932, forming then the Porterfield Aircraft Company in 1934. The new company was seen as a comeback for Porterfield and in 1937 it leased the former Federal Sash and Door Company factory. While it never achieved the numerical success of the larger light aircraft manufacturers such as Piper Aircraft, Aeronca and Taylorcraft, the planes were well made and popular with pilots. A focus on selling to Central and South American countries achieved some success. With the start of World War II, however, light aircraft production for civilian use came to a stop. Harlow Aircraft Company bought a one-third interest in the company in 1940. In an attempt to take advantage of the large growth in training due to the war, the company founded a technical school in December and purchased another in 1941. Bigger companies took great benefit from military contracts but Porterfield, with no large military orders forthcoming, eventually shut down. The final straw for the company came in 1942, when it failed to secure a contract to build liaison aircraft for the U.S. military.

Portfield was succeeded by the Columbia Aircraft Company, which was created when the firm Auchincloss, Parker & Redpath took over the former. However, Columbia itself soon went into receivership. The Ward Furniture Company later took over Porterfield's inventory and glider production contracts.

Edward Porterfield died from a heart attack in 1948.

John R. Hillman. John Hillman, P.E. (born April 20, 1963) is an American structural engineer who invented the hybrid composite beam (HCB) and founded the HC Bridge Company. In 2010, he was recognized with the Award of Excellence from Engineering News-Record.

Education and career
Born in North Dakota and raised in east Tennessee, Hillman received a bachelor's degree from the University of Tennessee in 1986 and a master's degree in civil engineering (MSCE) from Virginia Tech in 1990. Hillman has worked at several well-known bridge companies including Figg & Muller (see Eugene Figg), Jean Muller International (see Jean M. Muller), VSL, Teng & Associates in Chicago. He is currently employed at Kiewit (see Kiewit Corporation) in Denver, Colorado.

Development and design of the hybrid composite beam
At one point in his career, Hillman worked on developing fiber reinforced polymer (FRP) bridges. This led to his idea of the hybrid composite beam: combining a concrete and steel tied arch structure within an FRP box. A $320,000 grant from the Transportation Research Board's Innovations Deserving Exploratory Analysis (IDEA) program paid for the first HCB's to be constructed.(insert ENR ref tag) These beams were installed on a railroad test track (the Federal Railroad Administration's Facility for Accelerated Service Testing (FAST) loop at the Transportation Technology Center near Pueblo, Colorado). There the beams successfully supported a heavily-loaded train.

The hybrid composite beam is single structural element, a beam. It is constructed as a composite of three materials steel strands, concrete, and fiber reinforced polymer. The materials are arranged in a manner that the materials act as what would traditionally be separate structural elements. The concrete is in the shape of an arch and carries compressive load internal to the beam. The steel strands act as a tie for the arch and carry the tensile load internal to the beam. The FRP shell carries the shear and bending moment internal to the beam. This means that the beam acts structurally in a hybrid nature, somewhere between a tied-arch and a beam.

Awards and distinctions
 2010 Award of Excellence from Engineering News-Record for creating a new type of structural beam.

Kogi State Polytechnic. Kogi State Polytechnic was established in 1993, and is located in Lokoja, Kogi State, Nigeria. It is owned and operated by Kogi State. 
As of 2007 it was accredited by the National Board for Technical Education (NBTE) to give certificates in Art and printing, Business, Engineering, Finance and Science Computing at the National Diploma and Higher National Diploma levels.
In December 2009 the polytechnic presented 16 programs for accreditation to a visiting team of NBTE officials, mainly for the new schools of Engineering and Environmental Technology, Applied Science and Management Studies. The Rector said the school had to be able to offer core engineering and technology programs in order to fulfill its mandate.

In October 2005 the Kogi state governor, Alhaji Ibrahim Idris approved disbursement of N80 million to the polytechnic. He announced this at the first convocation ceremony, which covered academic sessions from 1992/93 to 2003/2004 and graduated 21,646 students.

In December 2005 a large number of hoodlums disrupted the matriculation ceremony of fresh students, set fire to the rector's office and damaged several vehicles before escaping. The incident may have been related to a struggle over who would succeed the rector, an Igala by tribe.
In March 2010 seventy five people, including 18 students of the Polytechnic, were crushed to death by a cement truck that ran out of control. In protest, students barricaded the Lokoja/Abuja highway, set fires and vandalized vehicles.   Governor Bello Appointed Dr Salisu Usman Ogbo as the Acting Rector Of Kogi State Polytechnic on the 7th April 2020 and confirmed his appointment as the substantive Rector on 11th February 2021 in order to consolidate the achievements he made and bring back the lost glory of the polytechnic.

ClearCube. ClearCube is a computer systems manufacturer based in Austin, Texas, owned by parent company ClearCube Holdings. The company became known for its blade PC products;  it has since expanded its offerings to include desktop virtualization and VDI. It was founded in 1997 by Andrew Heller (former IBM Fellow) and Barry Thornton as Vicinity Systems.

In 2005, ClearCube derived about a third of its revenue from virtual infrastructure products sold into the financial services sector, with the majority of the rest of the revenue coming from customers in the health-care and government sectors. Since 2005, ClearCube has continued to focus on virtualization-capable hardware and management software, which has led to strong revenue growth. In 2011, the company announced 50% year-over-year revenue growth due to the strong performance of its virtual desktop products.

In 2011, ClearCube acquired Dallas-based Network Elites. The acquisition brought roughly 25 additional employees to the company and expanded ClearCube's Cloud services capabilities.

Partnerships 
Until 2005, IBM was a reseller of the entire product line of ClearCube. Afterwards, IBM bundled some of its own hardware with ClearCube's software, and also diversified its software offering to include Citrix and VMware products. When IBM sold its PC division to Lenovo, the latter also began reselling ClearCube blades. Other major PC manufactures, like HP, also began to compete in the blade PC niche around this time. Other resellers of ClearCube products included Hitachi and SAIC.

In 2008, ClearCube spun off its software division as VDIworks, and while VDIworks has developed additional OEM relationships, the two companies remain closely associated in OEM partnership, and share the same investors and owners. In January 2008, ClearCube also introduced products implementing Teradici's PC-over-IP protocol, including two dual DVI thin clients, the I9420 I/Port and C7420 C/Port, which connect to the blades using copper-based and fiber-optic Ethernet, respectively.

Fokker D.IX. The Fokker D.IX was a Dutch single seat, single engine fighter aircraft, the final, more powerful evolution of the Fokker D.VII World War I success, flown in 1921. The sole example was purchased by the US Army Air Service but not developed further.

Design and development
The D.IX was the final development of the D.VII, an outstanding World War I fighter. It had a 300 hp (224 kW) Hispano-Suiza 8Fb (Type 42) water-cooled V-8, much more powerful than the D.VII's original 160 hp (120 kW) Mercedes D III engine and even most other engines experimentally fitted to this airframe.  Engine installation apart, the D.VII and D.IX were externally similar apart from their empennages.

The D.IX was a single bay biplane, its wings constructed in Fokker's established fashion with two box spars and fabric covering. The interplane struts were N-form while the cabane structure included two fully triangulated forward struts connecting to the forward spar, and a pair of single struts connecting to the rear spar. Ailerons were only fitted on the upper planes.

Its welded steel tube fuselage was flat sided, with the single seat open cockpit behind the trailing edge of the upper wing.  The straight edged fin and rudder appeared small though the latter extended down to the keel.  The strut braced tailplane was placed on top of the fuselage.  The D.IX's fixed conventional undercarriage was of the single axle type, with the mainwheels on V-struts.  This was much like that of the D.VII but the airfoil shaped axle fairing was enlarged to contain a fuel tank, an arrangement first trialed in the Fokker V.36.  An extra strut from the rear of the tank to the central fuselage underside helped to support it.

The D.IX prototype first flew in 1921.

Operational history

The D.IX was sold to the US Army Air Service (USAAS) in 1922 and shipped to their experimental centre at McCook Field where they had earlier tried a variety of different engines in D.VIIs. They designated it the PW-6. Instead of the original engine a locally built licensed version of the Hispano Type 42, the 320 hp (238 kW) Wright M-2 was fitted.  They also fitted armament, two fixed 7.7 mm (0.303 in) machine guns in the upper engine cowling, firing through the propeller.  Though it had a maximum speed about 20% greater than that of the standard D.VII and climbed twice as fast, the USAAS concluded it was not worth further development.

Boeing Model 306. The Boeing Model 306 was the designation for a series of aircraft drafted in 1935 that achieved neither design nor production status. They included the Model 306 bomber, Model 306 flying boat, and Model 306A airliner.

Design
In 1935, Boeing drafted several configurations of aircraft loosely based on both the Boeing XB-15 research and experience with the Boeing 314 Clipper aircraft. Each design was a "tailless" variation of those existing models with a flying wing layout, or a creative extension of the theme. They all featured extended trailing aileron/elevators that could perform their function without disrupting the wing performance. The wings were consistently swept about 35 degrees. The immaturity of the designs is evident in the flying boat drawings, which feature neither outrigger pontoons nor stabilising sponsons to keep the aircraft upright in the water. Each land based design featured tricycle landing gear as a feature when taildragger configurations were the standard of the time.

Subaru Industrial SX engine. The Subaru Industrial SX engine series from Subaru Industrial Power Products are designed specifically for use with snow throwers, also known as snow blower. The line includes four models, the 6 horsepower SX17, the 7 horsepower SX21 and the 9.5 horsepower SX30 and the SX40-14 horsepower

Technology
The SX line incorporates many of the same technology features as other Subaru industrial engines; most notable is Overhead Cam (OHC) technology. Overhead Cam technology has been proven to enhance engine performance. The technology allows the intake and exhaust valves being positioned for optimum engine performance, which offers lower resistance for the air/fuel mixture flow.  Overhead Cam engines also have fewer moving parts and produce less mechanical noise than competitive technologies.

Applications
The SX engines are designed specifically for use with snow throwers.

Engineer Regiment (Denmark). The Engineer Regiment () is a regiment in the Royal Danish Army with base in Skive in Jutland. The soldiers of this regiment are trained in skills such as demolition, bomb disposal, bridge construction, defending against chemical, biological and radiological hazards, and much more. The engineer troops are also trained to fight alongside infantry regiments in combat zones if needed.

This regiment was formed by the amalgamation of nearly all of the Danish military engineering corps into one regiment in 1997, simply named Ingeniørregimentet. The core of the Danish combat engineers are the so-called armored engineers. These units usually work in detached squads, each under the command of and attached to an infantry company, and equipped with an M113. Their roles are combat demolition, minefield clearing, basic mine laying and EOR. They are also extensively trained as infantry, to support the ordinary troops in combat. Besides these units, the regiment has the different work fields of combat engineers (construction, EOD, CBRN) spread out over different companies.

Structure
Today the Engineer Regiment has three battalions:
  1st Armored Engineer Battalion (1 PNIGBTN)
  Staff Company
  1st Armored Engineer Company
  2nd Armored Engineering Company
   3rd Armored Engineering Company
  2nd Explosive Ordnance Disposal Battalion (2 EODBTN)
