Rice paper plant

In Europe, around the 1900s, a paperlike substance was originally known as rice paper, due to the mistaken notion that it is made from rice. In fact, it consists of the pith of a small tree, Tetrapanax papyrifer, the rice paper plant.

The plant grows in the swampy forests of Taiwan, and is also cultivated as ornamental plant. In order to produce the paper, the boughs are boiled and freed from bark. The cylindrical core of pith is rolled on a hard flat surface against a knife, by which it is cut into thin sheets of a fine ivory-like texture.

Dyed in various colors, this rice paper is extensively used for the preparation of artificial flowers, while the white sheets are employed for watercolor drawings. Due to its texture this paper is not suited for writing.

Mulberry Paper

See also: Washi

The sort of paper that many people think of when hearing the term ice paper (smooth, thin, crackly, strong) is not actually made from rice at all. The paper is made from fibers from the bark of the mulberry tree. It got the name ice paper because it was used to make packets for rice. This sort of paper is used for origami, calligraphy, paper screens and clothing, etc. It is much stronger than commercially made wood-pulp paper. Although paper can be made from rice straw, this is not the ice paper that people usually think of.

The correct name for this type of paper is, depending on the type of mulberry used, kozo (Broussonetia papyrifera, the paper mulberry), gampi (Wikstroemia diplomorpha), or mitsumata (Edgeworthia chrysantha). The fiber comes from the bark of the mulberry, not the inner wood or pith, and traditionally the paper is made entirely by hand.

The branches of the mulberry shrubs are harvested in the fall, so the fiber can be processed and the paper formed during the cold winter months, because the fiber spoils easily in the heat. The branches are cut into sections two-three feet long and steamed in a large kettle, which makes the bark shrink back from the inner wood, allowing it to be pulled off like a banana peel. The bark can then be dried and stored, or used immediately. There are three layers to the bark at this stage: black bark, the outermost layer; green bark, the middle layer; and white bark, the innermost layer. All three layers can be made into paper, but the finest paper is made of white bark only.

If the bark strips have been dried, they are soaked in water overnight before being processed further. To clean the black and green bark from the white bark, the bark strip is spread on a board and scraped with a flat knife. Any knots or tough spots in the fiber are cut out and discarded at this stage.

The scraped bark strips are then cooked for two or three hours in a mixture of water and soda ash. The fiber is cooked enough when it can easily be pulled apart lengthwise. The strips are then rinsed several times in clean water to rinse off the soda ash. Rinsing also makes the fiber brighter and whiterine kozo paper is not bleached, it naturally pure white.

Each bark strip is then individually inspected, by hand, against a white background or lit from behind by a lightbox. Any tiny pieces of black bark and other debris are removed with tweezers, and any knots or tough patches of fiber missed during scraping are cut out of the strips. The ultimate goal is to have completely pure white bark.

The scraped, cooked, and cleaned strips are then laid out on a table and beaten by hand. The beating tool is a wooden bat that looks like a thicker version of a cricket bat. The fibers are beaten for about half an hour, or until all the fibers have been separated and no longer resemble strips of bark.

The prepared fiber can now be made into sheets of paper. A viscous substance called formation aid is added to the vat with the fiber and water. Formation aid is polyethylene oxide, and it helps slow the flow of water, which gives the papermaker more time to form sheets. Sheets are formed with multiple thin layers of fiber, one on top of another.

Edible paper



Rice paper can come in squares or circles

Edible rice paper is used for making fresh summer rolls (also called spring rolls) or fried spring rolls in Vietnamese cuisine, where the rice paper is called bh trg or bh ?a nem. Ingredients of the food rice paper include white rice flour, tapioca flour, salt, and water. The tapioca powder makes the rice paper glutinous and smooth. It is usually sold dried in thin, crisp, translucent round sheets that are wrapped…(and so on)

Seversky Aircraft

The Seversky Aircraft Company was founded in 1931 by Alexander de Seversky, a Russian expatriate and veteran WWI pilot who had lost a leg in the war. In the beginning, many of Seversky Aircraft’s designers were Russian and Georgian engineers whom Seversky had rescued from Stalin’s purges by bringing them to the United States, including Michael Gregor and Alexander Kartveli, who would go on to design many of Republic’s most famous aircraft.

After several failed attempts, Seversky Aircraft finally won a design competition for a new United States Army Air Corps fighter, and was awarded its first military contract in 1936 for the production of its Seversky P-35.

In 1939, Seversky Aircraft again entered in a military fighter competition, this time with the much improved AP-4. Unfortunately, the contract was instead awarded to the somewhat inferior Curtiss P-40, but the Army Air Corps were very pleased with the aircraft’s medium- and high-altitude performance and ordered 13 additional AP-4s for testing.

Republic Aviation

By April 1939, the Seversky Aircraft Corporation had lost $550,000, and Seversky was forced out of the company he had founded. The board, led by financier Paul Moore, voted Wallice Kellet to replace him as president, and in September 1939, the company was reorganized as the Republic Aviation Corporation. Seversky continued to fight for his company, and the matter was not resolved to his satisfaction until September 1942.

Meanwhile, Seversky’s AP-4 continued in development, finally going into production as the P-43 Lancer. 272 P-43s were eventually produced, with 108 of them being sent to China to be used against the Japanese. Many passed through the hands of the AVG Flying Tigers,[citation needed] whose pilots were pleased with the plane’s performance at altitudes up to 30,000ft (9,100m), while their P-40s were ineffective at altitudes over 20,000ft (6,100m) Unfortunately, Claire Chennault disliked the early P-43’s lack of self-sealing fuel tanks and armor, and declined to retain the plane for his crews.

In 1939, both Republic and Curtiss participated in an Army competition to develop a lightweight interceptor. Curtiss submitted a lightweight version of the P-40 designated the XP-46 while Republic submitted a similar design designated the XP-47. Both designs were based on a lightweight aircraft built around an Allison V-1710 V-12 engine, with the Republic design using a turbosupercharger. In the end, neither design showed a significant improvement over the P-40, and neither was produced.



A 1943 advertisement for REPUBLIC AVIATION from Flight & Aircraft Engineer magazine

Further development of the P-43 continued in the form of a lightweight version using a Pratt & Whitney R-2180 radial engine. The resulting aircraft was known as the XP-44. When the R-2180 didn’t produce the expected horsepower, Republic switched to the Wright R-2600. Despite possessing 1,600horsepower (1,200kW), this engine couldn’t be turbo-supercharged and Republic finally modified the design again, this time to accommodate the enormous Pratt & Whitney R-2800 Double Wasp engine, which produced 1,850horsepower (1,380kW). The resulting aircraft, now known as the P-44, was truly impressive. Capable of speeds of 404mph (650km/h) at 20,000ft (6,100m), and a climb rate of 4,000ft (1,200m) per minute, the aircraft would have been an exceptional interceptor. Unfortunately, the aircraft was capable of carrying no more fuel than the P-43, and the Double Wasp engine was far more thirsty, significantly limiting the aircraft’s range.

As the air war in Europe progressed, the Army was discovering that what it really needed was a long range fighter capable of escorting bombers into Germany. Alexander Kartveli was called to the Army’s Experimental Aircraft division and told of the new requirements, and that the P-44 would not be ordered in its current configuration. This was a devastating setback for Kartveli and Republic Aircraft because Kartveli knew the XP-44 could not be redesigned to meet these new requirements. On the train back to New York, he began…(and so on)

Flimsy Parts The top of the phone is also know to have some flex issues.[3]

Battery cover It has been stated in some official and unofficial reviews,[cite this quote] that the battery cover is very difficult to open. The User’s Manual shows that you only have to push out the battery cover, yet this is very difficult to accomplish.[citation needed] An easy fix for this is to put a eraser on the cover and use it to slide the cover open.

Tube Bending is a metalworking process used to permanently form stock tubing in to the shape of a die. Straight tube stock can be formed using a bending machine to create a variety of single or multiple bends and to shape the piece into the desired form. This process can be used to form complex shapes out of different types of ductile metal tubing.[1].



The picture is piping on an air condition system. Note that the bend kinks a little at the elbow, didn’t use an elaborate mandral.

Process

The process of Tube Bending involves using mechanical force to push stock material pipe or tubing against a die, forcing the pipe or tube to conform to the shape of the die. Often, stock tubing is held firmly in place while the end is rotated and rolled around the die. Other forms of processing including pushing stock through rollers that bend it into a simple curve. [2] For some tube bending processing, a mandrel is placed inside the tube to prevent collapsing. The tube is also held in tension by a wiper die to prevent any creasing during stress. A wiper die is usually made of a softer alloy i.e. aluminum, brass to avoid scratching or damaging the material being bent.

Tubing Geometry

A straight cylindrical tube can be transformed into a vast variety of shapes depending upon the needed application. A tube can be bent in multiple directions and angles. Although a single die can produce various shapes, it cannot shape other tube sizes and make different bend radii. Common simple bends consist of elbow (2-90 degrees), and U-bends. Complex bends include helical and coiled (more than one wrapping revolution), complex two-dimensional, and complex three dimensional bends as well. One side effect on the workpiece as a result of this process is the deformation of the wall thickness. The wall along the inner radius of the tube becomes thicker and the outer wall becomes thinner, depending on the tension in the tubing, the workpiece material, and the radius of the bend.

Tubing Specifications

Tube diameter can vary from 1/4″ - 8″ or approximately 6.3 mm - 203 mm. The cross section generally consists of a thin-wall with wall thickness varying from 0.031″ - 0.375″ or approximately 0.79 mm - 9.5 mm.

Mandrel Style

In production of a product where the bend is not critical a plug mandrel can be used. A form type tapers the end of the mandrel to provide more support in the bend of the tube. When precise bending is needed a ball mandrel (or ball mandrel with steel cable) should be used. The conjoined ball-like disks are inserted into the tubing to allow for bending while maintaining the same diameter throughout. Other styles include using sand, cerrobend, or frozen water2. These allow for a somewhat constant diameter while providing an inexpensive alternative to the aforementioned styles.

Process Results

There are several factors that effect the process results:- Workpiece material - Stainless steel, mild steel, copper, brass, aluminum, titanium, etc.- Bend geometry- Lubrication - type and quality- Sturdiness of workholding methods- Rigidity of actual bending equipment- Surface finish of holding tools

Tool Materials

Much of the tooling is made of hardened steel or tooled steel to maintain and prolong the tools life. However wherever there is a concern of scratching or gouging the work piece, a softer material such as aluminum or bronze is utilized. For example, the clamping block, rotating form block and pressure die are often formed from the hardened steel because the tubing is not moving past these parts of the machine. On the other hand, the pressure die and the wiping die are formed from aluminum or bronze to maintain the shape and surface of the workpiece as it slides by.

Power Requirements

The power required to bend the tubing is directly dependent on the tubing’s material,diameter, and wall thickness. For a wall thickness of 0.035 inches and a tubing material of aluminum the typical power requirements range from 4 to 80 foot-pounds. While steel tubing from of the same thickness typically requires power in the range between 12 and 245 foot-pounds.

Calculations

To calculate the speed at which a particular bend can be made in the workpiece, one must utilize the following formula where ? is the angle of the bend (in degrees) and R is the rate of the bend (in degrees per second).Speed = ?/R
