Caproni Sauro-1. The Caproni Sauro-1 (), or Caproni Tricap, was a light, single-engine cantilever monoplane, seating two in tandem, built in Italy in the early 1930s for touring.  Despite good performance and favourable test reports, only one was built.

Design and development

The Caproni Sauro-1 was not a Caproni design, but was built by them to a design from Emmanuele Trigona, leading to the alternative name Tricap (Trigone Caproni).  It was an aerodynamically clean cantilever monoplane with a low inverted gull wing. The wing was thick with a wide chord at the root, tapering both in plan and in thickness along the span to rounded wing tips.  Structurally the Sauro was a mixture of wood and chrome steel frames, covered with plywood and fabric.  On the wings the plywood was stress bearing.  Camber changing gear linked the neutral position of the ailerons and the angle of incidence of the tailplane; the ailerons maintained their normal opposing deflections for lateral control.  The fixed, conventional undercarriage took advantage of the inverted gull wing by placing the main legs at the lowest points of the wings, keeping the legs short and the track wide.  Shallow, full chord fairings enclosed the legs and part of the mainwheels, which had rubber shock absorbers and brakes.

The Sauro was powered by a 97 kW (130 hp) Farina T-58 radial engine within a domed cowling that left its five cylinders individually exposed.  Behind the engine the fuselage was ovoidal in cross-section and tapered only slowly to the tail.  It had a chrome steel frame, covered with plywood and fabric.  The two tandem cockpits, the forward one over the wing and the other just behind its trailing edge, had long headrest deckings behind them that extended to the tail. The cockpits were equipped with dual controls; those of the forward position could be disconnected in flight. Both seats had room for a parachute. The tail surfaces were conventional, steel-framed and covered with a mixture of aluminium and fabric, with the tapered tailplane set at mid-fuselage with an angular fin and rudder above.  The rudder ended above the fuselage, angled to allow for elevator movement.  A steel shod, rubber-sprung tailskid was mounted at the end of the fuselage.

The Sauro was built at Caproni's main Taliedo works, then tested at Guidonia Montecelio under military markings.  The aircraft was judged a success, with good performance and handling, but there was no development or production.  Trigona carried over some features of the Sauro into a fighter design but this was abandoned in 1943.

Carstairs House Tramway. The Carstairs House Tramway operated between Carstairs railway station and Carstairs House between 1888 and 1895.

History

The tramway was built by Joseph Monteith who owned Carstairs House. The construction engineers were Anderson and Munro, Electrical Engineers, 136 Bothwell Street, Glasgow.

Its purpose was to provide transport for his family and guests to and from Carstairs railway station. He pioneered the use of hydroelectric power, and constructed a power station to provide electricity for the house and tramway.

The system was described in the Leeds Times of Saturday 18 May 1889 as follows:

Closure

Electric services probably ceased around 1895 and then the line was operated for goods traffic using horse power for a few more years. The remains of the tramway were sold in the 1930s.

Israel Railways JT 42BW. The JT 42BW is a class of four axle Bo'Bo' diesel electric locomotives manufactured by Alstom's (previously by Vossloh and now by Stadler.) Meinfesa plant in Spain for Israel Railways (IR). The locomotives were the primary passenger locomotive unit used by IR through the 2000s.

Description

The locomotives are of the Prima type, produced at Alstom's plant in Valencia, Spain in collaboration with GM-EMD; the locomotives use EMD traction equipment and an EMD 710 engine. They were acquired to provide additional passenger services created as a result of investment in the 1990s which included the re-opening of several lines to passenger traffic. The locomotives are used to propel push-pull trains - a typical formation (2009) uses one locomotive, five double deck coaches, and a double deck driving trailer; the vehicles were the main passenger locomotive of IR, and half of its locomotive fleet (2007).

The locomotives were ordered in several batches between 1996 and 2006, the second batch of ten units allowed the 6 axle JT 42CW freight locomotives to return to their intended duties after they were transferred to passenger work due to lack of locomotives.

Two units, numbers 739 and 741 were rebuilt after being involved in accidents at Ahuzam and Beit Yehoshua.

In 2011 IR ordered 24 four axle Bo'Bo' Euro 3000 AC locomotives from Alstom Valencia successor company Vossloh España; these locomotives inherit some design features from the JT 42BW, including the use of an EMD 710 engine, though unlike the JT 42BW the locomotives use AC motors controlled by IGBT electronics.

Aeroméxico Flight 230. Aeroméxico Flight 230 experienced a hard landing at Chihuahua International Airport on July 27, 1981. Thirty-two people were killed when the McDonnell Douglas DC-9-32 jet aircraft was heavily damaged by impact with the ground and fire on approach in high winds.

Aircraft involved 
The aircraft involved was a McDonnell Douglas DC-9-32, registered as XA-DEN with MSN 47621/729. At the time of the crash, it was 7 years old.

Accident sequence 

The flight was uneventful until landing at Chihuahua. There were isolated cumulonimbus clouds with strong squalls and showers during approach and landing. Upon touchdown, the aircraft bounced once and struck the ground; the aircraft then slid off the runway, broke up and caught on fire. Thirty-four passengers and crew were able to flee the wreckage; the smoke and fire caused the deaths of those that remained trapped.

Gable CAD. Gable CAD, or Gable 4D Series, was a British architectural computer-aided design package initially developed in the early 1980s.

History
Gable CAD was developed at the University of Sheffield in the mid-1980s under the leadership of Professor Bryan Lawson. It was spun out into Gable CAD Systems Limited (incorporated in 1984) and retained links with the university until its demise in 1996 when a court order was made for compulsory winding up.

An early building information modeling application, Gable CAD was an advanced 2D and 3D design package with different modules, and was operated via a Windows-style interface and mouse running on UNIX. It was possible to create detailed 3D models and then generate 2D drawings or rendered visualisations from the data.

The assets of the company were acquired by Auxer in 1997 and aimed to complete the conversion of Gable CAD to Windows NT but this does not appear to have ever been released.

Para-Ski XS. The Para-Ski XS is a Canadian powered parachute that was designed and produced by Para-Ski of Mascouche, Quebec. The aircraft was supplied as a completed aircraft or as component kits for amateur construction.

Design and development
The aircraft was designed to be an all-terrain vehicle, capable of operating cross-country on wheels, skis, floats and flying under a canopy. As such it incorporates some design features that are unusual on powered parachutes. It features a custom made Para-Ski parachute-style high-wing, two-seats-in-tandem accommodation, quadracycle landing gear and a single  Rotax 582 engine in pusher configuration. To allow land and water operations the propeller has a rudder behind it, in the manner of an airboat, for steering via a set of handlebars. For surface operations the parachute is stowed in a specially designed compartment under the rear seat and the handlebars steer the wheels or the float-fitted water rudders. In flight the XS is steered either by the rudders, by foot pedals that actuate the canopy brakes, creating roll and yaw, or by a combination of both.

The aircraft is made from welded aluminum with the axles made from steel. It includes a fairing to provide protection for the occupants and a shield to keep water and stones out of the propeller during land and water operations. The aircraft is capable of taking off from water, provided the wing can be laid out on the shoreline without getting wet. The wing is a high-performance design that allows a fast cruising speed for a powered parachute of .

In 1998 the XS design was altered to allow it to also optionally mount a hang glider-style wing, transforming it into an ultralight trike and allowing faster cruising speeds than the parachute wing permits.

SS Conister. SS Conister (I) No. 145470 – the first vessel in the company's history to bear the name – was a coastal cargo vessel which was purchased by the Isle of Man Steam Packet Company from Cheviot Coasters Ltd, in 1932.

Construction & dimensions
Conister was built by the Goole Shipbuilding Company, Goole, in 1921, and originally named Abington. Her engines were supplied by C. and D. Holmes Ltd of Hull. Her construction costs are not recorded. She was a single-hatch coaster which had a length of 145'; beam 24'1"; depth 10'9" with a tonnage of .
Her machinery was aft, and she had two masts forward of the funnel.

Service life
Originally named Abington, she entered service with Cheviot Coasters Ltd. in November 1921, operating from Newcastle-upon-Tyne. She was bought by the Isle of Man Steam Packet Company in January 1932 for £5,500, (equivalent to £ in ) when her name was changed to Conister.

Conister was engaged in general cargo work and was frequently to be seen in Ramsey, unloading goods from Liverpool, before sailing on to Douglas.

Conister was the last coal-fired ship in the company's fleet and the last using reciprocating triple-expansion engines. During the Second World War, Conister was kept busy maintaining the lifeline to the Island.
On 27 October 1940 Conister was severely damaged by a bomb during an air attack.

Disposal
With the impending introduction into service of her successor , Conister was put up for sale. On 26 January 1965 she was sold to Arnott Young & Co., Glasgow, and was taken under tow to Dalmuir by the tug Campaigner for scrapping.

Conister was the last single-hatch steamer, regularly working in the Irish Sea.

SIMPL. Synchronous Interprocess Messaging Project for LINUX (SIMPL) is a free and open-source project that allows QNX-style synchronous message passing by adding a Linux library using user space techniques like shared memory and Unix pipes to implement SendMssg/ReceiveMssg/ReplyMssg inter-process messaging mechanisms.

Mechanism
A client thread sending a message is BLOCKED (the process thread execution is temporarily suspended) until the server thread sends a received message acknowledgement, processes the message, and executes a reply. When the server thread replies the client thread becomes READY (unblocked). The server thread typically loops, waiting to receive a message from a client thread.

Blocking synchronizes the client thread execution, blocking it and implicitly schedules the server thread to be scheduled for execution without requiring explicit process control work by the kernel to determine which thread to run next as with other forms of IPC.

The send and receive operations are blocking and synchronous, reply doesn't block, the client thread is already blocked waiting for the reply and no additional synchronization is required. The server thread replies to the client and continues running while the kernel and/or networking code asynchronously passes the reply data to the client thread and marks it READY for execution.

Advantages of synchronized message passing
Synchronized Message Passing has the following advantages:

 Simple coding model simplifies the task of partitioning a complex system and aids in testing
 Inherent thread synchronization coordinates the execution of communicating programs
 No data buffering is required
 Simplification of network interactions - threads can be in different programs on different machines

Limitations
SIMPL does not appear to be thread safe.

Similar projects
There is one other QNX-inspired synchronous message passing projects available for Linux. SRR IPC (for Send/Receive/Reply) by Sam Roberts and Andrew Thomas of  Cogent Real-Time Systems, Inc. which is related to the SIMPL project and adds a QNX-compatible API layer. SRR is a loadable kernel module designed to be QNX API compatible to facilitate porting of code.
