NER Class K. The North Eastern Railway (NER) Class K classified as Class Y8 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting.  It was designed by Thomas W. Worsdell and five of these tiny engines were built in 1890. These were numbered 559-63.

Description
The Class K design was not just small, it was diminutive, and as Class Y8 these were the smallest steam locomotives used by the LNER. They were fitted with steam and hand brakes only, never having vacuum brakes, and were unusual in having no bunker behind the cab for the coal, but rather having the small amount of coal required stored in a bin at the back of the footplate.

The Y8s were built with 'marine' type boilers, i.e. with a cylindrical flue into which the grate fitted. Between 1902 and 1904, they were all re-boilered with more traditional boilers similar to those fitted to the NER Class H locomotives.

Originally all of the Y8s were fitted with a single whistle of the bell-shaped type. 560, 561, and 563 acquired the organ type during LNER ownership. 559 also had one of these whistles fitted, but after 1940. In 1942 LNER No. 8091 (NER No. 560) acquired the chime whistle from the LNER Class A4 4469 Sir Ralph Wedgewood when it was damaged during an air raid on York in 1942. By 1946, the original organ-pipe whistle had been restored.

Operation and preservation
The NER built the K class specifically to shunt the docks at Hull, and it was here that they performed for most of their lives. During World War I No.559 was used both at Woolwich Arsenal and by the Royal Engineers near the mouth of the Humber Estuary. In 1940-41 559 spent a second period on the Spurn Head Railway. No 8091 became Departmental Locomotive No. 55, and acquired a 50A shed plate, being the last of the class when finally withdrawn in June 1954.

All five K class locos survived into LNER ownership. However, the Depression-era reduction in dock traffic and the increased use of Sentinel shunters (LNER Class Y1 and LNER Class Y3) led to the scrapping of three Y8s in 1936/7. Numbers 559 and 560 survived to the 1946 renumbering, and were renumbered as 8090 and 8091 respectively. Both survived into British Railways (BR) ownership, but neither survived long enough to acquire an updated '60000' number plate. 8090 was withdrawn in November 1948.

None of the original five survived into preservation. After years of speculation, in 2022 the Beamish Museum announced plans to build a new K Class engine where its small size and marine type boiler are seen as perfect for the museum's short demonstration line.

Amdahl UTS. UTS is a discontinued implementation of the UNIX operating system for IBM mainframe (and compatible) computers. Amdahl created the first versions of UTS, and released it in May 1981, with UTS Global acquiring rights to the product in 2002. UTS Global has since gone out of business.

System requirements 
UTS Release 4.5 supports the following S/390 model processors and their successors:

 Amdahl 5990, 5995A, 5995M series of ECL processors
 Amdahl Millennium Global Server series of CMOS processors
 Fujitsu Global Server
 IBM ES/9000/9021 series of ECL processors
 IBM G4, G5 & G6 Servers (the 9672 R and X series of CMOS processors)

History
The UTS project had its origins in work started at Princeton University in 1975 to port UNIX to the IBM VM/370 system. Team members there were Tom Lyon, Joseph Skudlarek, Peter Eichenberger, and Eric Schmidt. Tom Lyon joined Amdahl in 1978, and by 1979 there was a full Version 6 Unix system on the Amdahl 470 being used internally for design automation engineering. In late 1979 this was updated to the more commonly ported Version 7.

In 1980 Amdahl announced support for Unix on the System 470. Five years later, IBM announced its own mainframe Unix, IX/370, as a competitive response to Amdahl.

The commercial versions of UTS were based on UNIX System III and UNIX System V. In 1986, Amdahl announced the first version to run natively on IBM/370-compatible hardware, UTS/580 for its Amdahl 580 series of machines; previous Unix ports always ran as "guests" under the IBM VM hypervisor. Version 4.5 was based on Unix System V, Release 4 (SVR4).

RA-1 Enrico Fermi. RA-1 Enrico Fermi is a research reactor in Argentina. It was the first nuclear reactor to be built in that country and the first research reactor in the southern hemisphere.

Construction started in April 1957, with first criticality on 20 January 1958. By contrast, the HIFAR reactor in Australia went critical just six days later, on 26 January 1958. The RA-1 reactor produced the first medical and industrial radioisotopes made in Argentina, and was used to train staff for the first two nuclear power stations there.

It is a pool type, with enriched uranium oxide fuel (20% U-235), light water coolant and moderator, and a graphite reflector. It produces 40 kilowatts of thermal energy at full authorized power.

It has been modernized on several occasions, and is currently used for research and teaching.

OpenSolaris for System z. OpenSolaris for System z is a discontinued port of the OpenSolaris operating system to the IBM System z line of mainframe computers.

History 
OpenSolaris is based on Solaris, which was originally released by Sun Microsystems in 1991. Sun released the bulk of the Solaris system source code in OpenSolaris on 14 June 2005, which made it possible for developers to create other OpenSolaris distributions. Sine Nomine Associates began a project to bring OpenSolaris to the IBM mainframe in July, 2006. The project was named Sirius (in analogy to the Polaris project to port OpenSolaris to PowerPC). In April, 2007, Sine Nomine presented an initial progress report at IBM's System z Technical Expo conference.

At the Gartner Data Center Conference in Las Vegas, Nevada in late 2007, Sine Nomine demonstrated OpenSolaris running on IBM System z under z/VM.  It was there that David Boyes of Sine Nomine stated that OpenSolaris for System z would be available "soon."

At the SHARE conference on 13 August 2008, Neale Ferguson of Sine Nomine Associates presented an update on the progress of OpenSolaris for System z.  This presentation included a working demonstration of OpenSolaris for System z.  During this presentation he stated that while OpenSolaris is "not ready for prime-time" they hoped to have a version available to the public for testing "in a matter of weeks rather than months."

In October, 2008, Sine Nomine Associates released the first "prototype" (it lacks a number of features such as DTrace, Solaris Containers and the ability to act as an NFS server) of OpenSolaris for System z to the public.  OpenSolaris for System z has a project page at OpenSolaris.org. OpenSolaris for System z is  available for download at no charge, and is governed by the same open source license terms as OpenSolaris for other platforms. All source code is available; there are no OCO (object code only) modules.

The port uses z/Architecture 64-bit addressing and therefore requires an IBM System z mainframe. Because the port depends on recently defined z/Architecture processor instructions, it requires a System z9 or later mainframe model and will not run on older machines. It also will not run on the release version of Hercules mainframe emulator, the needed changes are included in the SVN version 5470 of Hercules. It also requires the paravirtualization features provided by z/VM; it will not run on "bare metal" or in a logical partition (LPAR) without the z/VM hypervisor at Version 5.3 level or later. Also, because OpenSolaris uses a new network DIAGNOSE instruction, PTF VM64466 or VM64471 must be applied to z/VM to provide support for that instruction.  On 18 November 2008, IBM authorized the use of IFL processors to run OpenSolaris for System z workloads.

The Register reported in March 2010 an email from an insider saying that:

Time Sharing Operating System. Time Sharing Operating System, or TSOS, is a discontinued operating system for RCA mainframe computers of the Spectra 70 series.  TSOS was originally designed in 1968 for the Spectra 70/46, a modified version of the 70/45. TSOS quickly evolved into the Virtual Memory Operating System (VMOS) by 1970. VMOS continued to be supported on the later RCA 3 and RCA 7 computer systems.

RCA was in the computer business until 1971 when it sold its computer division to Sperry Corporation. Sperry renamed TSOS to VS/9 and continued to market it into the early 1980s. In the mid seventies, an enhanced version of TSOS called BS2000 was offered by the German company Siemens.

While Sperry – now Unisys – discontinued VS/9, the BS2000 variant, now called BS2000/OSD, is still offered by Fujitsu and used by their mainframe customers primarily in Germany and other European countries.

As the name suggests, TSOS provided time sharing features.  Similar to CTSS it provided a common user interface for both time sharing and batch, which was a big advantage over IBM's OS/360 or its successors MVS, OS/390 and z/OS.

Robot II. The Robot II was a mechanical 135 film camera by Robot  introduced in 1938.
It was a slightly larger camera than the Robot I, with some significant improvements but still using the basic mechanism. Among the standard objectives were 3 cm Zeiss Tessar and a 3 cm Zeiss Tessar in 1:2,8 and 1:3,5 variations, a 1:2,0/40 mm Zeiss Biotar and 1:4/7,5 cm Zeiss Sonnar.

The film cassette system was redesigned but it was only with the Robot IIa launched in 1951 that film could accept a standard 35 mm cassette. The special Robot cassettes type-N continued their role for take up. A small bakelite box was sold to allow people to rewind colour film into the original cassettes as demanded by the film processing companies. The camera was synchronized for flash. The swinging viewfinder was retained but now operated by a lever rather than moving the entire housing. Both the deep purple filter and the yellow filter were eliminated in the redesign. Some versions were available with a double wind motor which could expose 50 frames. The Second World War stopped civilian production of the Robot but it was used as a gun camera by the Luftwaffe.

The Robot II took square photographs in the 24×24mm format, which allowed 50 exposures to fit on a 36-exposure film. It featured an all-metal Rotor shutter (1/4 to 1/500), a direct vision finder, and a screw mount for interchangeable lenses by Schneider. The standard lens is a Schneider Xenon 40 mm f1.9.

Also available was the Robot Star II/50, with a double spring motor for 50 exposures and a Xenar 38 mm f2.8 lens.

Di-positronium. Di-positronium, or dipositronium, is an exotic molecule consisting of two atoms of positronium.  It was predicted to exist in 1946 by John Archibald Wheeler, and subsequently studied theoretically, but was not observed until 2007 in an experiment performed by David Cassidy and Allen Mills at the University of California, Riverside.  The researchers made the positronium molecules by firing intense bursts of positrons into a thin film of porous silicon dioxide. Upon slowing down in the silica, the positrons captured ordinary electrons to form positronium atoms. Within the silica, these were long lived enough to interact, forming molecular di-positronium.  Advances in trapping and manipulating positrons, and spectroscopy techniques have enabled studies of Ps–Ps interactions.  In 2012, Cassidy et al. were able to produce the excited molecular positronium  angular momentum state.

Rexleigh Bridge. Rexleigh Bridge is a wooden covered bridge over the Batten Kill in Washington County, New York.  It is one of 29 historic covered bridges in New York State.

Town and Howe truss designs were patented by Ithiel Town in 1820 and William Howe in 1840, respectively.  The Rexleigh Bridge employs "the patented Howe truss, with paired diagonal timbers, single timber counters, and multiple vertical iron rods defining each truss panel.  The diagonals and verticals are connected to the upper and lower chords by means of cast-iron bearing blocks."  Those bearing blocks are "embossed with the name of their manufacturer, 'R. Comins, Troy, N.Y.,'" and, although the timber used is local, the bridge "appears to be a rare surviving example of this type of prefabricated nineteenth-century bridge construction."

It was individually inventoried by the New York State Office of Parks, Recreation and Historic Preservation in 1977.

It is one of four Washington County covered bridges submitted for listing in the National Register of Historic Places in one multiple property submission. The others are the Buskirk Bridge, the Eagleville Bridge, and Shushan Bridge.  All four were listed on the National Register of Historic Places on March 8, 1972.

Windmill (sailing dinghy). The Windmill is an American sailing dinghy that was designed by Clark Mills as a one-design racer and first built in 1953.

The Windmill hull design was developed into the US1 single-handed catboat in 1974.

Production
Originally intended to be amateur-constructed from four sheets of plywood, the boat was also commercially manufactured from fiberglass. The design was built by Johannsen Boat Works, Lockley Newport Boats and Advance Sailboat Corp. in the United States, but it is now out of production. A total of 5700 examples of the type have been completed.

Design

The Windmill is a recreational sailboat, built predominantly of plywood or fiberglass in the form of a double hull with a foam core, resulting in an unsinkable boat. It has a fractional sloop rig with aluminum spars. The boat and is sailed only with a jib and mainsail, no spinnaker and no trapeze. The hull has a rounded plumb stem, a conventional transom, a transom-hung rudder controlled by a tiller and a retractable daggerboard. It displaces ,

The boat has a draft of  with the daggerboard extended and  with it retracted, allowing beaching or ground transportation on a trailer or car roof rack.

For sailing the design is equipped with jib and mainsail windows for visibility. It also has an internal 2:1 mechanical advantage outhaul, a 4:1 boom vang controlled by the boat's skipper and a 4:1 Cunningham. The boat has adjustable jib fairleads and a mainsheet traveler, plus an Elvstrom bailer.

The design has a Portsmouth Yardstick racing average handicap of 90.2 and is normally raced with a crew of two sailors.

Operational history
In a 1994 review Richard Sherwood wrote, "the Windmill is a high-performance sloop that can be built from plans or from a kit, or purchased complete. She is very light and planes quickly. Class rules are strict, and neither spinnakers nor trapezes are allowed. With a double hull and closed-cell foam, the boat is unsinkable. This type of construction also results in a very rigid boat."

The boat is supported by an active class club, the Windmill Class Association.

Caproni Vizzola F.5. The Caproni Vizzola F.5 was an Italian fighter aircraft that was built by Caproni. It was a single-seat, low-wing cantilever monoplane with retractable landing gear.

Development

The F.5 was developed in parallel with the Caproni Vizzola F.4, with which it shared a common airframe. Design began in late 1937 by a team led by F. Fabrizi. The aircraft had a welded steel-tube fuselage and wooden wings; the fuselage was covered with flush-riveted duralumin, while the wing had a stressed plywood skin. The F.5 (standing for Fabrizi 5) had a two-row 14-cylinder Fiat A.74 R.C. 38 radial engine, unlike its cousin the F.4, which Fabrizi and his design team intended to be powered by a water-cooled engine. The F.4 project was not pursued immediately because the Italian Air Ministry held its proposed engine in disfavor, but development of the F.5 continued.

The F.5 prototype first flew on 19 February 1939. The aircraft displayed very high maneuverability during official testing, prompting an order for both a second prototype and 12 preproduction models. The last of the preproduction aircraft was selected for use as a prototype in a renewed F.4 program, but the rest of the F.5 order was delivered to the Regia Aeronautica (Italian Royal Air Force).

No F.5 production models were built as Caproni decided to produce the more developed Caproni Vizzola F.6M fighter instead.

Operational history

The Regia Aeronautica assigned the 11 preproduction F.5 fighters to the 300° Squadriglia, 51° Stormo for operational use. By 1942, they were serving as night fighters in the 167° Gruppo.

The F.5 was offered to foreign customers. It has been said that the Aeroplani Caproni subsidiary in Peru acquired the license rights for local manufacture, but no F.5s were ever built in Peru.
