John Trinkaus. John W. Trinkaus (July 17, 1925 – November 11, 2017) was an American business consultant, management and behavior researcher, and engineer. In 2003, Trinkaus was awarded the Ig Nobel Prize in literature for "meticulously collecting data and publishing more than 80 detailed academic reports about things that annoyed him." As a result, his work received mainstream media coverage, with stories appearing in The New York Times, Newsweek, and other media.

Life and career 
John W. Trinkaus served in the United States Army Air Forces in World War II. After the war, he studied electrical engineering at New York University and subsequently worked as an engineer for Bendix Aviation, Curtis Wright Corporation, and Sperry Rand before embarking on an academic career. In 1961, Trinkaus obtained a Master's degree in engineering management from Baruch College, City University of New York, followed in 1976 by a doctorate in management from New York University.

Trinkaus taught in the Zicklin School of Business at Baruch College in New York, eventually becoming Professor of Management and Dean, and was a Visiting Distinguished Professor at St. John's University. His research interests included executive education, the history of management thought, and observation of various social practices. In addition to his academic work, Trinkaus also consulted for the Ford Foundation, the Small Business Administration, and the Interracial Council for Business Opportunity. Trinkaus was particularly active in promoting and facilitating minority startups and studied the contribution of African Americans to the history of American management and management thought.

Trinkaus had three children with his wife Irene. He died on November 11, 2017, in New Hyde Park, NY, aged 92.

Ig Nobel prize 
In 2003, Trinkaus was awarded the Ig Nobel Prize in literature for "meticulously collecting data and publishing more than 80 detailed academic reports about things that annoyed him." This included, among numerous other things, studies about:

 The number of items people bring to express lines at supermarkets
 How often drivers come to a complete stop at stop signs
 The average wait time to see a doctor at their office
 Taste preferences for brussels sprouts
 How many people pay for the candles in churches
 How many people wear baseball caps with the bill facing backwards

Many of Trinkaus's published articles are terse reports based on observation and counting the occurrence of things. The majority of his articles have been published in two journals, both founded by Robert B. Ammons: Perceptual and Motor Skills and Psychological Reports. He replicated the same studies in different years and generally found that bad habits are getting more widespread with time. Trinkaus's research earned him recognition in the media, including becoming the subject of stories by NPR, The New York Times, Newsweek, and New Scientist.

Sandstone branch railway. The Sandstone branch railway (also known as the Black Range railway) was a branch railway line between Mount Magnet and Sandstone in the Mid West region of Western Australia.

History 
It was built in 1910, and closed in 1949; it was lifted in 1950.

The Mt. Magnet-Black Range Railway Act 1907, assented to on 20 December 1907, authorised the construction of the railway line, while the Railway (Mt.Magnet-Black Range) Discontinuance Act 1948, assented to on 21 January 1949, permitted its discontinuation. More specifically, the act permitted the removal of the line to be used for the construction or maintenance of other railway lines in the state, or to be sold by the ministry of railways.

Route 
It was connected to the Mullewa – Meekatharra railway at Mount Magnet.

Locations on line 
 Mount Magnet –   (from Perth)
 Warrambu – 
 Mount Ford – 
 Paynesville  
 Intersection with No 1 Rabbit Proof Fence at 
 Anketell –  
 Jundoo –  
 Sandstone – 

An interactive map of the Sandstone line is available at OpenStreetMap.

Proposed link to Leonora 
Prior to and after construction, there were suggestions of connecting to the railway line at Leonora, approximately  south east of Sandstone. Such a connection would have created a loop line linking the Northern Railway with the Eastern Goldfields Railway.  The proposal was not successful.

Reputation of branch line
The railway was considered by the railway commissioner of the time in the mid-1930s to be the worst railway in Western Australia.
 
Post-Second World War austerity issues were given as part of reason for closing in 1948 due to shortage of  rails for the required repairs to remain open.

Legacy
The Sandstone railway goods shed built in 1910 was considered to be of heritage significance, having survived long after closing of the line. The Sandstone railway station and the station master's house have been demolished but the goods sheet remains on the Shire of Sandstone heritage list, which also includes a railway tank stand and a railway dam at Sandstone.

At Mount Magnet, the railway station and platform, railway dam, railway bridge and the railway workers houses are on the Shire of Mount Magnet heritage list.

APRS Calling. APRS Calling is a manual procedure for calling stations on the Automatic Packet Reporting System (APRS) to initiate communications on another frequency, or possibly by other means. It is inspired by Digital Selective Calling, a part of the Global Maritime Distress Safety System. It also builds on existing digital procedures inherited from morse code and radioteletype operation. ITU Q codes are used in conjunction with APRS text messages to implement APRS calling. APRS calling is intended to complement monitoring voice calling frequencies.

Procedure
The calling station sends a QSX signal to the station or group they wish to reach using an APRS text message. The QSX should include the necessary information for contact, possibly including frequency and mode.
Once the called station or stations are ready to communicate on the specified channel, they answer using a QSX text message on APRS.
The stations shift communications to the arranged channel.

Example
All APRS transmissions include the call sign programmed into the APRS unit. The text message doesn't necessarily require the station identification commonly seen in voice, CW or RTTY exchanges, so long as the programmed call sign is valid.

This example shows N6BRK announcing a net on 147.480 MHz to the NALCO APRS group. When ready to communicate on the coordinated frequency, KJ6VVJ responds with an acknowledgment to the QSX. If the operating mode isn't obvious in context of the frequency, the initiating stations QSX should specify what it is.

HMAS Marlean. HMAS Marlean (Q20) was a channel patrol boat commissioned into and operated by the Royal Australian Navy (RAN) during World War II. She was one of thirteen similar vessels, known to Sydney siders as the 'Hollywood Fleet'.

Prior to the War, she was a private vessel built by J. Williams & Sons laid down in 1938 and launched in 1939. she was  in length which had been increased by 10 feet to . Her beam was . Keel and frames were of spotted gum with huon pine planking. She was powered by two six cylinder Gray marine engines each of 105 hp. She was arranged to sleep eight persons in three double and two single berth cabins and included a deck saloon, dining saloon, toilet, shower room, and an annex galley at the aft end of the dining salon which included a built in refrigerator.

She was requisitioned and later commissioned by the RAN on 30 November 1941. Marlean was armed with .303 Vickers machine guns fore and aft and depth charge racks on the stern.

During the Battle of Sydney Harbour on 31 May and 1 June 1942, following the first explosions, Marlean proceeded to the western end of the boom net to assist the protection of the harbour.  Following the Battle of Sydney Harbour (often referred to as the attack on Sydney Harbour), HMAS Marlean continued patrol duties at Sydney, Port Kembla, and Newcastle.

On 14 April 1944, the command of Marlean was transferred to the Naval Auxiliary Patrol (NAP) unit of the RAN.

Marlean was awarded a Battle Honour for her wartime service, "Darwin 1942", yet there is no record of her arriving at Darwin or serving in Darwin. It appears the transfer did not occur, because on 27 April 1942, just twelve weeks after the first Japanese bombing raid on Darwin, it is documented that Marlean (together with Steady Hour) returned to Sydney Harbour from patrol duties at Port Kembla and all three vessels – Marlean, Nereus and Winbah, were at anchor in Sydney Harbour on 31 May 1942.

Fate
Marlean was consumed by fire and the explosion of a depth charge at Obelisk Bay, Sydney Harbour on 12 November 1944.

Vizastar. Vizastar was the first integrated software package for the Commodore 64 home computer. At the time of its introduction it was the only package for the C64 with features comparable to Lotus 1-2-3, including spreadsheet, database and graphics components. It had the ability to split or merge files between the database and spreadsheet components and could split the screen into up to nine windows.

To alleviate the C64's somewhat limited memory capacity when running complex software, Vizastar included a ROM cartridge that provided an additional 4K RAM and also served as a form of copy protection. This allowed the program to remain compatible with third-party floppy disk drives for the C64, such as the Indus GT and MSD Super Disk, unlike many copy protected packages. Commodore serial printers were supported, as were RS-232 and Centronics printers with the appropriate interface.

The spreadsheet had a maximum size of 1000 rows by 64 columns, or 64,000 cells, but because only about 10k of memory was left available after the program was loaded, not all the cells could be used. The additional cells provided flexibility in the dimensions of the spreadsheet. The spreadsheet module had a macro feature that could execute a series of commands at once.

The database had a capacity of 1200 fields, which could each hold 124 characters. In order to keep down the programs memory requirements, it was necessary to export a database to the spreadsheet module in order to sort it.

It was later ported to the Commodore 128.

Reception
Commodore Microcomputers stated that "Vizastar packs so much muscle into the 64 that it is hard to believe you're running it on a 64K machine". The reviewer approved of the software's speed, "excellent documentation", and use of windows to show multiple portions of a document. He concluded, "I ... could find no major weaknesses. It seems to be a 64 application program beyond reproach ... Vizastar is an all-star!" Compute!'s Gazette said "There's nothing quite like Vizastar 128 for the Commodore 128 ... Each application, if available separately, would be a good solid program". The magazine concluded that it was "a gem of a program", and "as close as it comes" to Lotus 1-2-3 for the 128. Info said of Vizastar 128, "Despite minor quirks this is a powerhouse program with few of the compromises normally associated with integrated programs". The magazine added that if the company could combine it with Vizawrite Classic, "it would become the Commodore 128 Appleworks".

Conveyor pulley. A conveyor pulley is a mechanical device used to change the direction of the belt in a conveyor system, to drive the belt, and to tension the belt.  Modern pulleys are made of rolled shells with flexible end disks and locking assemblies. Early pulley engineering was developed in Australia by Josef Sitzwohl in 1948 and later by Helmuth Lange and Walter Schmoltzi in Germany.

Components
Pulleys are made up of several components including the shell, end disk, hub, shaft and locking assembly. The end disk and hub may be one piece. The locking assembly may also be replaced with a hub and bushing on lower tension pulleys. The shell is also referred to as the rim in some parts of the world.

The pulley shaft is typically sized following CEMA B105.1 in the Americas or AS 1403 in Australia.
