RWD 18. The RWD 18 was a four/five seat STOL (Short Take-Off and Landing) utility aircraft designed and built in Poland from 1936.

Development 
DWL studied a small twin-engined STOL utility aircraft as a private venture due to the lack of official support, hoping to kindle new markets in multi-engined, utility and business aircraft.
The RWD 18s safe handling characteristics and STOL capability were derived from the full span leading edge slats, which were operated by servo suction from a leading edge mounted venturi tube, and the fixed tri-cycle undercarriage. Construction was to have been mixed with wooden cantilever high wings having anhedral on the inner sections, fitted with full span powered leading edge slats and trailing edge flaps. The fuselage was a welded steel tube framework faired with wooden formers, covered with plywood and fabric, fitted out with a dual control cockpit and a bench seat in the cabin for two or three. At the rear of the fuselage a cantilever twin finned wooden tail unit was fitted to improve low-speed yaw control and stability. 

The spatted undercarriage legs were cantilevered from the engine nacelles and the fuselage under the nose with the main wheels fitted with 'Bendix' pneumatic brake units and the nosewheel steerable from the rudder bar. Any engine of around 150 hp could be fitted, but the prototype was fitted with 150 hp Cirrus Major four-cylinder inverted in-line engines fitted in nacelles at the junctions of the inner and outer wings.

An RWD 9 was converted to the RWD 20, by fitting a tri-cycle undercarriage, to speed the development of the RWD 18s, with extensive trials carried out including rough and ploughed field landings, take-offs and taxiing. Flight trials were scheduled to be carried out in December 1939 but the incomplete prototype was destroyed in an air raid during the German invasion of 1939.

Taha El Sherif Ben Amer. Taha El Sherif Ben Amer (June 28, 1936 - March 6, 1978) was a Libyan engineer and politician.

He was born in the city of Benghazi, Libya in June 1936. He spent his childhood in Benghazi where he finished his primary school and high school. He was awarded a scholarship in order to pursue his education in Cairo, Egypt. In 1959 he obtained a bachelor's degree with honours in Civil Engineering from Ain Shams University.

Soon after graduation, he went back to Benghazi to work as a Junior Engineer and establish an engineering office which involved in many engineering projects across the eastern region of Libya. After the revolution in Libya in 1969, Taha El Sherif was appointed as the Deputy Minister of Transportation until 1971. Then, he became the Minister of Transportation to 1975. Soon after this date, he was selected as the Secretary of State.

On March 6, 1978 Taha El Sherif Ben Amer died in a helicopter crash of which he was going to visit a project near the city of Tripoli with the East German Politburo member Werner Lamberz who was the party's second most important ideological spokesman.

Duct (industrial exhaust). Industrial exhaust ducts are pipe systems that connect hoods to industrial chimneys through other components of exhaust systems like fans, collectors, etc. Ducts are low-pressure pneumatic conveyors to convey dust, particles, shavings, fumes, or chemical hazardous components from air in the vicinity to a shop floor or any other specific locations like tanks, sanding machines, or laboratory hoods. Ducts can be fabricated from a variety of materials including carbon steel, stainless steel, PVC, and fiberglass.  They can be fabricated through rolling (preferable for ducts of 12" or more in diameter) or extruded (for ducts up to 18").

HVAC systems do not include this category of industrial application, namely exhaust systems.  A distinction from HVAC system ducts is that the fluid (air) conveyed through the duct system may not be homogeneous. An industrial exhaust duct system is primarily a pneumatic conveying system and is basically governed by laws of flow of fluids.

Fluid flow 
The conveying fluid that flows through the duct system is air. Air transports materials from the hood to a destination. It is also instrumental in capturing the material into the flow system. Air is a compressible fluid, but for engineering calculations, air is considered as incompressible as a simplification, without any significant errors.

Design 
Process design of exhaust system will include
 Identification of contaminants, their density and size
 Deciding of air flow
 Sizing of the ductwork
 Calculation of resistance
 Finalizing the capacity of blower, etc.
The goal is to keep contaminants out using minimum airflow. It is estimated that increase in an inch wg of static pressure can add a few thousands of dollars to the operation cost per annum.

Genteq. Genteq is a subsidiary of Regal-Beloit Corporation, one of the largest manufacturers of electric motors in the world. Genteq is the rebranding of Regal's GE ECM, GE Capacitors and GE Commercial Motors divisions, which occurred in 2009.

Genteq develops and manufactures electronically commutated motors (ECM) and capacitors for residential and light commercial heating and air conditioning (HVAC) systems. The company is based in Fort Wayne, Indiana, with manufacturing facilities in Mexico.

Genteq is the developer of BLAC motor technology, and the DEC Star blower.

DEC Star blower technology has been developed into the DEC Star Fan Panel System, a development made by IBEC:  Innovative Building Energy Controls, a Kansas corporation headed by Dave Ogle, Kansas Master Mechanical and the developer of the Net Positive RTU using the DECStar technology.

DEC Star Fan Panels are both a retro-fit, and new manufacturing application for large energy reductions in commercial HVAC applications.

DEC Star blower technology is a key component to the Power Scout program, a comprehensive approach to building/facility wide energy and demand reductions.

Genteq markets its products to original equipment manufacturers (OEMs), as well as to HVAC contractors, distributors and technicians.

History
Regal acquired General Electric’s Commercial and HVACR Motors and Capacitors businesses in 2004. These acquisitions from General Electric effectively doubled Regal's size.

As part of that acquisition, Regal acquired the rights to use the GE brand through 2009. Nearing the end of that licensing period, Regal rebranded these divisions as Genteq in February 2009.

General Electric developed an Electronically Commutated Motor (also called Electronically Controlled Motor), or ECM, technology for use in residential and light commercial heating and air conditioning systems in North America in the mid-1980s.  The GE ECM motor was the first ultra-high efficiency motor for home heating and air conditioning systems, providing greater home comfort and energy efficiency.

The DEC Star blower was added to the Genteq product line in 2014.

The DEC Star Fan Panel system began development in 2015, and is currently available now, in 2016 through the IBEC corporation.  www.ibec-group.com.

National Appliance Energy Conservation Act. The National Appliance Energy Conservation Act of 1987 (NAECA; ) is a United States Act of Congress that regulates energy consumption of specific household appliances. Though minimum Energy Efficiency Standards were first established by the United States Congress in Part B of Title III of the Energy Policy and Conservation Act (EPCA), those standards were then amended by the National Appliance Energy Conservation Act of 1987, the Energy Policy Act of 1992 and the Energy Policy Act of 2005.

All of these laws and regulations have to do with creating mandatory standards that deal with the energy efficiency of certain household appliances.  These standards were put in place to ensure that manufacturers were building products that are at the maximum energy efficiency levels are that are technically feasible and economically justified.

History

The National Appliance Energy Conservation Act of 1975 (NAECA) was enacted to help create uniform appliance efficiency standards at a time when individual states were creating their own standards. The NAECA established a conservation program for major household appliances, however no real standards came into existence until the 1980s when appliance manufacturers realized it was easier to conform to a uniform federal standard then individual state standards.

The National Appliance Energy Conservation Act of 1987 amended the Energy Policy and Conservation Act and was introduced and supported by democratic Senator Bennett Johnston, Jr. from Louisiana in January 1987. The new amendments to the act established minimum efficiency standards for many household appliances, including:
Refrigerators
Refrigerator-Freezers
Freezers
Room Air Conditioner
Fluorescent Lamp Ballasts
Incandescent Reflector Lamps
Clothes Dryers
Clothes Washers
Dishwashers
Kitchen Ranges and Ovens
Pool Heaters
Television Sets (withdrawn in 1995)
Water Heaters

Congress set the initial efficiency standards at the start of the act then set a schedule for the United States Department of Energy to review them. The act also put into place laws prohibiting manufacturers from making any representations about the energy efficiency of any product on this list without first being tested by Federal testing procedure, and disclosing the results of such tests. Lastly the new act set new rules for when state regulations will be superseded by federal regulations in regard to testing and labeling requirements, and energy conservation standards.

British European Airways Flight 142. 

British European Airways Flight 142 (callsign Bealine 142) was a scheduled service between London Heathrow Airport and Naples Airport. On 22 October 1958, it was flown by a Vickers Viscount 701, registered G-ANHC, and named "Sir Leopold McClintock". During its flight, the Viscount collided with an Italian Air Force North American F-86E Sabre over Anzio, Italy.

Accident
Flight 142 was flying at 23,500 feet towards Naples when it collided with the F-86E. The F-86E was the leading aircraft of four on a tactical training exercise when it hit the Viscount. Both aircraft crashed, with the loss of all people on the Viscount. The F-86 pilot, Captain Giovanni Savorelli, didn't use his ejector but parachuted down successfully and spent 6 months in hospital.

Investigation
While no blame was assigned for the accident, it was noted that the Viscount had strayed out of its airway and into a military-prohibited area.

AN/ASQ-213 HARM targeting system. The AN/ASQ-213 HARM targeting system (HTS) is a targeting pod mounted to either of the engine inlet hardpoints of an F-16 Fighting Falcon aircraft. It enables the aircraft to track the location of hostile radar systems in any weather, and identify them to allow for usage of the AGM-88 HARM missile or other air-to-ground weapons. It greatly assists in Suppression of Enemy Air Defenses (SEAD) and Destruction of Enemy Air Defenses (DEAD) operations, where surface-to-air missile (SAM) sites are directly attacked or threatened, and therefore suppressed, by aircraft carrying anti-radar missiles and other munitions. While the firing of anti-radar missiles (AGM-88 HARM) in Harm As Sensor (HAS) mode, an HTS pod greatly reduces the workload of the pilot, increases the precision of the HARM, and allows HARMs to be fired while pointed away from the SAM site being attacked when in Equation of Motion (EOM) mode.

As an aircraft maneuvers closer to a SAM site and is scanned by the radar for longer periods, the quality of the HTS pod's report of the location of the SAM site increases. This is represented by the PGM (Position Quality) number. A single F-16 is capable of attaining a PGM5 track, the lowest quality track, up to PGM2. When combined with the F-16's Link 16 datalink system, a team of aircraft is capable of Pseudo-range multilateration to obtain the position of SAM systems with a high degree of accuracy, allowing for the highest quality track, PGM1.

In combat, the pod displays the range, bearing, and type of threats to the aircraft in relation to itself. During flight, the pilot may adjust the area scanned by the pod as well as the frequencies scanned to optimize threat detection and ranging.

Development 
After the deactivation of the successful EF-4C Wild Weasel IV, the contract for the creation of the HTS pod was awarded to Texas Instruments (The defense business of which was sold to Raytheon in 1997 for $2.95 Billion USD). 

After the successes of the original design of the HTS pod, future upgraded variants featured vastly improved ranging speed and improved threat identification, as well as improving the frequency covered and the number of targets which could be tracked at once.
