Natural Earth projection. The Natural Earth projection is a pseudocylindrical map projection designed by Tom Patterson and introduced in 2008. It is neither conformal nor equal-area, but a compromise between the two.

In its original presentation, the projection's origin is described as "The impetus for creating the Natural Earth projection was dissatisfaction with existing world map projections for displaying physical data." Further criteria follow, ending with "The ideal projection needed to be both functional and rather familiar in appearance."

The Natural Earth projection was originally designed in Flex Projector, a specialized software application that offers a graphical approach for the creation of new projections. Subsequently, Bojan Šavrič developed a polynomial expression of the projection.

The projection may also be referred to as the Natural Earth I projection, due to subsequent development of a Natural Earth II projection. The same group later developed the Equal Earth projection.

Definition
The Natural Earth projection is defined by the following formulas:

 

where
  and  are the Cartesian coordinates;
  is the longitude from the central meridian in radians;
  is the latitude in radians; 
  is the length of the parallel at latitude ;
  is the distance of the parallel from the equator at latitude .

 and  are given as polynomials:

In the original definition of the projection, planar coordinates were lineally interpolated from a table of 19 latitudes and then multiplied by other factors. The authors of the projection later provided a polynomial representation that closely matches the original but improves smoothness at the "corners".

Sombold So 344. The Sombold 344 Schußjäger (Shoot Fighter) was a rocket-powered aircraft designed in 1943/44 by engineer Heinz Sombold in Naumburg/Saale, Germany. The project came about when the Luftwaffe was seeking an emergency interceptor to combat the allied bombing raids over Nazi Germany in the last years of World War II.

Description
The So 344 was originally intended as a parasite escort fighter armed with two MG 81 machine guns and one MK 108 cannon, but its original design was changed in January 1944. 
The second version of the aircraft retained the two machine guns, but its front section was a detachable explosive nose with stabilizing fins filled with 400 kg of explosives. The pilot sat in the cockpit near the tail which was in the back section. The plane proper had a wingspan of 5.7 m and a length of 5.3 m. Including the ejectable nose its length would be 7 m.

The plane would have been released from a mother plane upon reaching combat altitude. Then it would ignite its single Walter HWK 109-509 rocket engine and dive towards the enemy bomber fleet at a 45-degree angle. Shortly before contact it would release its explosive nose, equipped with a proximity fuze, into the center of the combat box formation in a way that it would damage as many bombers as possible. Then it would try to get away with the remaining fuel in its rocket engine and finally land on its fixed skid. 

Owing to the extreme risks for the pilot inherent in the operation of this aircraft, the Sombold So 344 is sometimes listed as a suicide weapon. However, it was not intended as such, even though the chances of survival would have been very limited for the pilot of such a dangerous artifact.
 
A 1/5 scale model was built for aerodynamic tests, however the project was abandoned shortly before the end of the European conflict.

AM General BRV-O. The AM General BRV-O (Blast Resistant Vehicle - Off road) competed in an original field of six vehicle designs as part of the JLTV Joint Light Tactical Vehicle program that will replace the Humvee. AM General designed the BRV-O JLTV to provide better protection, performance, payload, transportability, reliability and affordability than the current Humvee. 

In August 2012, the Army and Marine Corps selected the BRV-O as one of three designs for the Engineering and Manufacturing Development (EMD) phase of the program. Also selected were designs offered by Lockheed Martin and Oshkosh.

Oshkosh's L-ATV was selected as the winner of the JLTV program on 25 August 2015. The company was awarded a $6.75 billion low rate initial base contract with eight options to procure the first 16,901 vehicles for both the Army and Marines. The current JLTV procurement objective stands at 53,582 vehicles - 49,099 vehicles for the U.S. Army and 4,483 vehicles for the U.S. Marine Corps. On 8 September 2015, AM General announced it would not protest the decision. 

The Pentagon Operational Test & Evaluation Office released a report of how each JLTV prototype performed in a Limited User Test (LUT) in February 2016, finding that the BRV-O would “require a significant redesign” to meet threshold force protection requirements, and it had reliability problems demonstrating 526 "Mean Miles Between Operational Mission Failure," compared to 2,968 miles for the Humvee and 7,051 for the winning L-ATV.

Industrial dryer. Industrial dryers are used to efficiently process large quantities of bulk materials that need reduced moisture levels. Depending on the amount and the makeup of material needing to be dried, industrial dryers come in many different models constructed specifically for the type and quantity of material to be processed. The most common types of industrial dryers are fluidized bed dryers, rotary dryers, rolling bed dryers, conduction dryers, convection dryers, pharmaceutical dryers, suspension/paste dryers, toroidal bed or TORBED dryers and dispersion dryers. Various factors are considered in determining the correct type of dryer for any given application, including the material to be dried, drying process requirements, production requirements, final product quality requirements and available facility space.

Westland CL.20. The Westland CL.20 (aka Cierva-Lepère C.31) was a two-seat autogyro designed and built by Westland Aircraft between 1934 and 1938. One flying prototype and six airframes were built, which had control problems and insufficient lift. Before these problems could be solved the programme was abandoned and the prototype was scrapped in 1938.

Development
Before the Westland C.29 had proven to be a failure, "Teddy" Petter sought to design another cabin autogyro in collaboration with George Lepère, a French autogyro designer with the Lioré et Olivier aircraft company. The initial design was by Georges Lepère in association with the Cierva Autogiro Company and was based on the Cierva-Lepère C.L. 10B. Detailed design was by Westland's Arthur Davenport and Petter.

Construction was completed in December 1934 and in January 1935 taxi-ing trials were carried out at Yeovil by Harald Penrose, after which it was transported to the Cierva flight test centre at Hanworth Aerodrome, where Juan de la Cierva flew the prototype on its first flight on 5 February 1935. During development flying, carried out by R.A.C. Brie, the CL.20 exhibited over-sensitive lateral control and was unable to exceed a height of . To improve lift, a more powerful Niagra engine was fitted but this made little difference.

Despite the poor performance of the prototype, Teddy Petter persuaded Westland to manufacture another six airframes, but further development was abandoned due to emerging work as a result of the threat of war. At the end of development flying the prototype had logged 8 hours 31 minutes flying time over 61 flights, before the flying prototype was scrapped in 1938.

Design
Based on the CL.10B, the load bearing structure of the CL.20s fuselage was based on three welded seamless steel tubes (forming a flat bottomed triangle in cross section) carrying light alloy formers. On this, light alloy stringers were fixed and covered in fabric, producing a multi-faceted surface. The cabin structure consisted of a light-alloy arched former at the back with a wooden floor. On each side a large door and additional windows reached down to the bottom longeron, giving both excellent access and downward vision.

The three-bladed rotor could be folded for storage and transport. Three fins were fitted, two as endplates to the tail-plane, one half of which was fitted with negative camber and incidence, in order to help offset the effects of the rotor.

The CL.20 was initially powered by a  Pobjoy radial engine, driving a two-bladed tractor propeller, modified to include a power take-off shaft to spin up the rotors for take off. During flight testing, in an attempt to improve performance, a more powerful Pobjoy Niagara III was fitted.
