Azeotrope tables. This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture. Boiling points are reported at a pressure of 760 mm Hg unless otherwise stated. Where the mixture separates into layers, values are shown for upper (U) and lower (L) layers.

The data were obtained from Lange's 10th edition and CRC Handbook of Chemistry and Physics 44th edition unless otherwise noted (see color code table).

A list of 15825 binary and ternary mixtures was collated and published by the American Chemical Society. An azeotrope databank is also available online through the University of Edinburgh.

Utility helicopter. A utility helicopter is a multi-purpose helicopter capable of pursuing a wide array of tasks. They have proven useful in both civilian and military operations, with versatility being their defining trait.

Civil
Helicopters play a crucial role in various aspects of civilian safety. Police and fire rescue aircraft demonstrate exceptional versatility across a broad spectrum of tasks. Common applications for civilian utility include traffic surveillance, medical evacuations, news coverage, and search and rescue missions. Recently, usage has been extended to air evacuations, air and water pollution control, emergency cargo transportation (including blood, organs, and special equipment), and as helitankers in aerial firefighting. 

Traditionally, helicopters with three placed reciprocating engines, such as the 47G Series and the Hughes 300C were the primary choices for civilian use. However, the preference has been shifted towards turbine engines. The FH-100 and the Bell 206A JetRanger are examples of turbine engine helicopters which have proven to be more effective in operational scenarios. 

The arising issue with civilian use helicopters is the price tag of the turbine engine helicopters. With initial cost being around $100,000, difficulties are posed when budgeting for the necessary modifications. Such modifications include night vision capabilities, infrared, and radar.

Military 

In military terms, a utility helicopter is an aircraft designed to transport troops, but is versatile in performing various combat roles. These tasks include command and control, logistics, casualty evacuation, and fire support. The defining characteristics of these helicopters are lightweight frames capable of quick maneuvers, and space, for transporting troops and cargo. Common types of cargo include ammunition, weapons, and food.

These aircraft play a crucial role in military operations by providing defensive capabilities in scenarios of evacuation and cargo transportation, as well as offensive roles in fire support and surveillance. Their ability to adapt to different mission requirements contribute significantly to the success of military objectives.

Nakajima E8N. The Nakajima E8N was a Japanese ship-borne, catapult-launched, reconnaissance seaplane of the Second Sino-Japanese War. It was a single-engine, two-seat biplane with a central main-float and underwing outriggers. During the Pacific War, it was known to the Allies by the reporting name "Dave". This aircraft was identified by the British as the Nakajima KT-95 Dave.

Design and development
The E8N was developed as a replacement for the same company's E4N and was essentially an evolutionary development of the earlier reconnaissance seaplane, with revised wings of lesser area and taller tail surfaces. Seven prototypes were constructed, under the company designation MS, first flying in March 1934. These were duly engaged in comparative trials against competitors from Aichi and Kawanishi, with the E8N being the preferred option due to its superior manoeuvrability and ruggedness.

Operational history
The MS was ordered into production, designated Navy Type 95 Reconnaissance Seaplane Model 1 in October 1935. A total of 755 E8Ns were built by Nakajima and Kawanishi, production continuing until 1940. It was subsequently shipped aboard all the capital ships then in service, 16 cruisers and five seaplane tenders.

It was used successfully in the Second Sino-Japanese War not only for reconnaissance, but also for dive-bombing and artillery spotting.

One E8N was purchased in early 1941 by the German Naval Attache to Japan, Vice-Admiral Paul Wenneker, and dispatched on board the KM Münsterland to rendezvous with the German auxiliary cruiser Orion at the Maug Islands in the Marianas. The meeting occurred on 1 February 1941, and Orion thus became the only German naval vessel of the Second World War to employ a Japanese float plane.

The Royal Thai Navy placed an order for eighteen E8Ns in 1938. After delivery in 1940, they were reclassified as the BRN-1, but did not see any combat action until 1945, responding to the Allies Operation Livery. One BRN-1 was totally destroyed and two others were written off. The remaining fifteen served on after the war until lack of spare parts resulted in their decommissioning and scrapping.

Some aircraft remained in service with the fleet at the outbreak of the Pacific War, and one flew reconnaissance from the battleship Haruna during the Battle of Midway. In general, though, they were soon replaced by more modern aircraft such as the Aichi E13A and the Mitsubishi F1M and reassigned to second-line duties, such as a seaplane trainer, communications and liaison work.

Makino. , commonly known as Makino, is a machine tool builder with global sales and service, headquartered in Japan.

History
Makino was established in 1937 by Tsunezo Makino in Japan, developing Japan's first numerically controlled (NC) milling machine in 1958 and Japan's first machining centre in 1966.

The North American branch of Makino was formed through the 1981 merger of the  R. K. LeBlond Machine Tool Company of Cincinnati and the Makino Milling Machine Company of Japan. Resulting from the merger was the formation of what was then called "LeBlond Makino Machine Tool Company".

In 1996, LeBlond Makino became Makino, and in 1997 LeBlond Lathe Ltd. was formed as a parts and servicing subsidiary.

Innovations
In 1984, Makino introduced the first commercial high-speed spindle for milling. In 1990, Makino introduced Geometric Intelligence, the first servo-control software tailored to high-speed machining, and Flush Fine machining, a method for cutting hardened materials.

The company developed the first drop-tank wire EDM in 1994, and HQSF (High-Quality Surface Finish) technology with patented uSc additive in 1996, increasing the ability to finish parts without hand polishing when using a ram EDM. In 2003, Makino developed the first conventional horizontal wire EDM that automatically threads and machines with a 0.02mm diameter wire.

In 2006, the company developed High Energy Applied Technology (HEAT) for wire EDMs to increase speed in wire EDMing, and released the EDAC1 micro EDM ram machine. Makino is also the only manufacturer of a horizontal wire EDM, the UPJ-2. In 2007, Makino introduced SurfaceWIZARD wire EDM technology, designed to eliminate witness lines in stepped parts. Makino created ADVANTiGE™ Technology for the machining of titanium in 2010, which was recognized as a winner of Aviation Week's 2012 Innovation Challenge. 

In 2018, Makino introduced ATHENA, Makino's voice-activated technology, which is designed for machine tool users. It is intended to make humans more effective at translating, assimilating and analyzing the onslaught of big data.

WXP (software). WXP, the Weather Processor, is a weather data manipulation and visualization package developed at Purdue University in the 1980s.  In 1989, WXP was adopted by Unidata as the Unix-based weather analysis tool and was distributed to over 40 universities.  WXP became a showcase venture for Unidata which at the time was promoting many of the new standards of software development and user interaction.  In 1992, WXP was copyrighted and sold commercially through the Purdue Research Foundation.  WXP version 4 became widely used in the university community to develop weather web site.  The primary developer of WXP Dan Vietor developed the wxp.eas.purdue.edu web site which became one of the first weather web sites on the World Wide Web.  With the move of the developer to Unisys in 1998, the rights to WXP were transferred to the Unisys corporation. As of 2020, Unisys no longer supports WXP but the developer continues to maintain and support it.

Although many developers have played a role in WXP over the years, Dan Vietor is generally regarded as the main contributor.  His work in developing WXP was honored at the 2005 American Meteorological Society Annual Meeting, where he was presented the DeSouza Award by Unidata.

WXP is a commercially licensed product. WXP is still used by many web sites for data visualization including College of DuPage and Plymouth State University.

Techno-Cracked. Techno-Cracked is a theatrical animated short film, directed by Ub Iwerks and featuring Flip the Frog.

Synopsis
In this satire of the Technocracy, Flip the Frog is nearly killed by a menacing robot he builds to work for him.

Flip would rather not mow the lawn. He reads an article from "Unpopular Mechanics" entitled "Technocracy: Why be a Slave - The Mechanical Man Works While You Sleep". Flip makes his robot out of household parts but gives it a Jack-o'-lantern for a head. The mechanical man cannot follow directions and begins mowing down everything in sight. Flip blows up the robot with a stick of dynamite and finishes the lawn by himself.

Notes and comments
When the robot mows the welcome mat it reveals the word Nerts, a possible reference to either the card game or to a popular expression of the time -- "nertz". Some have speculated that Techno-Cracked may have been photographed in two-strip Technicolor.
