Type 517 radar. Type 517 radar is believed to be an A-band/VHF air search radar widely deployed on People's Liberation Army Navy surface vessels with 4 antennas in two crossed-brace supported pairs, one above the other, mounted in pairs on each side of a single tubular support carried on the turning gear.

Similar to the Russian P-8 'Dolphin'/KNIFE REST radar which China manufactures and deploys for the HQ-2 surface to air system complex, it is believed that Type 517 has similar capabilities and specifications. The system is manufactured by the Beijing Leiyin Electronic Technology Development Company (Chinese: 北京雷音电子技术开发有限公司).

Miter clamp. Mitre clamps or miter clamps clamps are designed to hold mitre joints together.

History 
The earliest mitre clamps are a simple spring in a C-shape with sharpened points that are sprung onto the outside corner of the mitre joint.

In a later design, right angled plates are higher than the screws and the holder. The screws go under the frame (work-piece) to be held, and the bit clamps down on the lower-edge of the frame.

Recent designs are more complicated; a rigid body holds one fixed and one moveable jaw activated by a cam. An example of newer clamps is Jim Chestnut's Clam Clamp.

Nallatech. Nallatech is a  computer hardware and software firm based in Camarillo, California, United States.
The company specializes in field-programmable gate array (FPGA) integrated circuit technology applied in computing. As of 2007 the company's primary markets include defense and high-performance computing. Nallatech was acquired by Interconnect Systems, Inc. in 2008,
which in turn was bought by Molex in 2016.

Background 
The company was founded by Allan Cantle ('Nalla' comes from 'Allan' spelled backwards) in 1993 and was backed by over £4 million of equity finance provided by Scottish Equity Partners and 3i. Cantle was the CEO for the firm, later moving into president and CTO roles.

In 2005 Nallatech announced a Scottish group known as the FPGA High Performance Computing Alliance, to work on a supercomputer.

Nallatech's direct sales team operates in two main geographic areas, one in the US and one in UK covering UK, Europe and rest of the world.  The team in the USA (Nallatech, Inc.) sales office in Eldersburg, Maryland and headquartered in Camarillo, California.

Nallatech is a member of the OpenPOWER Foundation.

Products
Nallatech was promoted for commercial off-the-shelf (COTS) FPGA technology applied in computing. According to David R. Martinez, Robert A. Bond, and M. Michael Vai, Nallatech systems are "based on a modular design concept in which the designer chooses the number of FPGAs, amount and type of memory, and other expansion cards to include in a system."

Nallatech is also known for its motherboards with PCI cards which provide a "high throughput connection over which a host PC can provide and receive data and monitor system performance."

On June 17, 2015, it released the 385A FPGA Accelerator Card, which includes the Altera Arria 10 / 1150 FPGA, PCI-Express form factor and works with most major servers, including IBM, HP and Dell.

In March 2011 the company announced a miniaturization service for their FPGAs.

In 2012, Nallatech has partnered with Altera, and integrated their PCI Express card with Stratix V FPGAs.

Xilinx's Xtreme DSP kit was developed with Nallatech, and like Xilinx, Nallatech uses "floating-point cores" in their FPGAs.

Constant-slope barrier. A constant slope barrier is a traffic barrier made of reinforced concrete and designed with a single slope that is used to separate lanes of vehicular traffic.  Its advantages compared to more complex shapes arise because its performance is not as affected by changes in the height of the roadbed during repaving.

The Texas Constant-Slope Barrier is  high and has a constant slope face that makes an angle of 10.8 degrees with respect to the vertical.  California has developed a constant slope barrier with an angle of 9.1 degrees with respect to the vertical.  The Texas Constant-Slope barrier has performed similarly in crash tests to the Jersey barrier.  The California design compared similarly to the F-Shape barrier in crash tests.

Toyota Motor Manufacturing Indiana. Toyota Motor Manufacturing Indiana (TMMI) is an automobile manufacturing plant located in Gibson County, Indiana, United States, nearly halfway between Princeton and Fort Branch, and mostly in Union Township. It is a subsidiary of Toyota Motor North America, itself a subsidiary of Toyota Motor Corporation of Japan. With over 7,000 employees, TMMI is the largest employer in the Evansville Area.

History 
Toyota Motor Manufacturing Indiana was built in May 1996 to begin production of a full-size pickup truck solely for the North American market. TMMI began production of the Tundra in 1999 for the 2000 model year, and Sequoia production began a year later for 2001. Both the Tundra and the Sequoia were new to the market and have only been sold in North America; the Tundra replaced the Toyota T100 in the US market.

In 2003, production of the Sienna minivan shifted to TMMI for the release of its redesigned 2004 model, while Toyota Motor Manufacturing Kentucky produced the Solara in place of the Sienna.

On July 10, 2008, Toyota announced that they would consolidate Tundra production at Toyota Motor Manufacturing Texas in San Antonio after 2008. Owing to the large unsold supply of Tundras and Sequoias, production of both Tundras and Sequoias would be suspended. Toyota also announced that production of the Highlander would be shifted to TMMI and would start in 2009. Production of the Sequoia later resumed, although at a reduced output.

Layout 
The roughly 950,000 square foot factory is split into two different plants. The original factory, "West Plant," originally built to produce Tundras, began producing Highlanders then Sequoias but now produces Highlanders, Grand Highlanders, and in September 2023 will begin producing the Lexus TX. TMMI later expanded to add "East Plant" which produces Siennas, and now produces the bulk of Highlander orders as well. Both plants have joined weld, stamping, and plastic production sections. East Plant also started producing Highlanders as of 2016. Both plants have undergone large expansions to support the high domestic and worldwide demands for the Highlander, and Grand Highlander.

TMMI is the sole source of Highlanders for all markets worldwide except China. Chinese-market Highlanders are made in China exclusively for the Chinese market.

Present automobiles produced 
 Lexus TX  (West Plant - 2023–present)
 Toyota Grand Highlander  (West Plant - 2023–present)
 Toyota Highlander  (West Plant - 2009–2024)  (East Plant - 2016–present)
 Toyota Sienna  (East Plant - 2003–present)

Past automobiles produced 
Toyota Tundra (1999–2008), production moved to Toyota Motor Manufacturing Texas
Toyota Sequoia (2000–2021), production moved to Toyota Motor Manufacturing Texas

Indian Institute of Chemical Technology. The CSIR-Indian Institute of Chemical Technology is a national-level research center located in Hyderabad, Telangana, India under the Council of Scientific and Industrial Research (CSIR). IICT conducts research in basic and applied chemistry, biochemistry, bioinformatics, chemical engineering and provides science and technology inputs to the industrial and economic development of the country. IICT has filed one of the maximum CSIR patents.

Activities

The research and development programmes of IICT relate to the development of technologies for pesticides, drugs, organic intermediates, fine chemicals, catalysts, polymers, organic coatings, use of low-grade coals, and value-added products from vegetable oils. Process design and mechanical engineering design form an integral part of technology development and transfer. IICT is also actively engaged in basic research in organic synthesis and catalyses.

Public health

An example of the institute's work is development of technology for accurate identification, of principal mosquito vector in rural endemic areas for designing suitable control measures of vector-borne diseases like malaria, filaria, Japanese encephalitis, dengue fever, etc.

In developing countries like India, classification and identification of the mosquito species from rural endemic areas are of paramount importance. The World Health Organization monograph which describes the taxonomic data in the form of a pictorial key is generally difficult to understand by a non-taxonomist. Keeping this difficulty in view, a novel software has been developed which is user-friendly and menu-driven. The package can be successfully used in mosquito control programs in rural areas. Rapid identification and greater accuracy are the salient features of the technology.

Claud Jones-class destroyer escort. The Claud Jones-class destroyer escorts were four destroyer escorts built for the United States Navy in the late 1950s. These ships were a diesel-powered version of the earlier  and were designed with the aim of producing a cheaper ship suitable for rapid production in wartime. These ships also had reduced armament and speed compared to their predecessors. They were not seen as effective anti-submarine warfare vessels by the United States Navy and were sold after only 15 years service to the Indonesian Navy.

Description
The class was designed under project SCB 131 as a cost-effective version of an anti-submarine warfare (ASW) ship that could be built quickly in case of rapid mobilization. The Claud Jones class had a standard displacement of  and were  at full load. The destroyer escorts were  long at the waterline and  overall with a beam of  and a draft of . The Claud Jones class had an aluminum superstructure, a tripod mast forward and a pole mast further back amidships, with two stacks.

Following the guidelines given to them, the designers chose a single-shaft diesel-powered ship to maximize cost effectiveness. The Claud Jones class were given four Fairbanks Morse 38ND8 diesel engines rated at . The class had a range of  at  and a maximum speed of .

The ships were initially armed with two /50 caliber guns, one located forward with a closed shield and one located aft with an open shield. For ASW, the destroyer escorts were equipped with two forward-firing hedgehog anti-submarine mortars, two fixed  Mark 32 Surface Vessel Torpedo Tubes and one depth charge rack placed over the stern. The fixed torpedo tubes were later removed and replaced with two triple tube mounts. In 1961, Charles Berry and McMorris received a Norwegian-designed Terne III ASW rocket-propelled depth-charge system.

The Claud Jones class was initially equipped with variable depth sonar, AN/SPS-10 and AN/SPS-6 search radars and SQS-29/32 hull-mounted sonar. The variable depth sonar was later removed. The vessels had a ship's company of 175 with 15 officers and 160 enlisted personnel. The class was not well-received and the designers were ordered to come back with another design, leading to the successor s.

Indonesian service
The four vessels of the class were transferred to the Indonesian Navy in 1973–1974. In Indonesian service, Samadikun (ex-John R. Perry) and Martadinata (ex-Charles Berry) had one of the 3-inch guns removed and given Soviet twin-mounted  guns and twin-mounted  guns. Monginsidi (ex-Claud Jones) and Ngurah Rai (ex-McMorris) kept their two 3-inch mounts and had twin-mounted 25 mm guns added.

ALCO DL-202. The ALCO DL-202-2 and DL-203-2 diesel-electric locomotive (known informally as the Black Maria) was an experimental freight locomotive produced by ALCO of Schenectady, New York. The primary diesel builders Alco, Baldwin and EMD pushed the War Production Board (WPB) for more opportunities to build more diesels. The Transportation Equipment Division of the WPB announced a production schedule on December 10, 1943, that allowed Alco to build one 4500 horsepower experimental diesel locomotive. This experimental diesel locomotive was to be built in the fourth quarter of 1944.  The two A units were built in January 1945 and the B unit at a later date in 1945. The two A units were put on test at Building No. 37 at Schenectady to work out problems with the connecting rods and  turbocharger in the Alco 241 engine, developed by both McIntosh and Seymour and ALCo. The total production run included 2 cab DL202-2 A units, and a single DL203-2 B (cabless booster) unit.  The locomotives were powered by a V12 ALCO 241 diesel engine, rated at . The units were released for test in September 1945.  The locomotive could attain a top speed of  (Freight) and  (Passenger).
With the B-B wheel arrangement and carbody construction, equipment layout and electrical gear these experimental units were the immediate predecessors of the FA units to come in early 1946. Outwardly, the bodies strongly resembled those on the DL-109, some of which were still under construction at Schenectady in early 1945.

The three units were numbered 1500A, B, C and were tested on the New York Central Railroad, the Delaware and Hudson Railroad, the New York, New Haven and Hartford Railroad, and the Bangor and Aroostook Railroad,
among others. As no orders materialized for such units, and no railroad bought the demonstrators, the set was scrapped in Schenectady New York September 1947.
