This Edison Ediphone voice recording electronic business machine is manufactured to suit a small office and is light enough to carry between work and home for use outside normal business hours. It is a dictation machine, also called by the competitor’s brand name ‘Dictaphone’, and is used for recording spoken words that would later be transcribed and typewritten. A wax cylinder would be installed onto the machine’s drum and the Reproducer on the machine would be lowered onto the cylinder. The user would speak a message into a microphone and the reproducer would then convert the sounds to scribed marks on the cylinder. Later, the cylinder could be played and the Reproducer would enable the sound to be amplified through an attached speaker. This machine is currently without its power cord, microphone and speaker horn. Thomas A. Edison extended the technology of the telegraph to his phonograph machine, invented in the late 19th century. It could record and play back sounds of music and voice on a manually operated mechanical machine that used wax cylinders to store the sound. He envisaged the way this technology could be an asset in the office, and he was right! However, most of his phonograph machines were used for entertainment, some for playing lessons, and some for-teaching languages. In 1916 Edison introduced the Ediphone, which grew in popularity after the First World War and into the late 1920s until flat round records replaced the wax cylinders. This Edison Ediphone is significant for improving the way business administration was carried out in the early 20th century, freeing up precious time for professionals and administrative personnel. It was the forerunner of audio tapes and digital technology. The Ediphone enabled letters to be dictated when the time and place suited and reduced the time professionals needed to spend with their secretaries. Secretaries were able to type the letters as they played the recording and they could replay the message if necessary.Voice recorder; a dictation machine; desktop model Edison Ediphone. The electronic machine is in a medal case with remnants of the original grey colour. It has a rectangular base with an A4-sized footprint and a domed hood that retracts halfway into the back of the base. The corners of the base have metal reinforcing, and a short metal bar is on the front centre edge of the lid and the base. A long metal drum is mounted inside the machine. A round device called a ‘reproducer’ is mounted above the drum. There is a folding handle on the left front of the machine and an angled stand with paper guides in front of the drum. A rear cover has the maker’s name stamped on it. An electrical socket with eight pins is recessed beside the cover.

Invented by a member of the Abbott family of Bendigo, scalebuoys came in various sizes and had a variety of uses such as the mining industry to prevent scale build up in boilers, automotive for car radiators and domestic for water purification. Its essential part is a sealed glass bulb containing a small amount of mercury and a combination of gases.This particular variety was made to be connected to a water tap with a screw attachment and a small outlet pipe. Scalebuoy sent to Alan Cowling from work colleague, Pat Curran in Tasmania. Pat Curran was working as the CEO of a retirement village and found the scalebuoys in the equipment there. Noting the Bendigo manufacturing logo, he decided to send it to Alan. The original owner of the scalebuoys is unknown.sciences, instruments - general, scalebuoy

First available in ScubaPro’s catalogue in 1966, the ScubaPro Automatic Decompression Meter was a break through in diving technology and a forerunner to the modern dive computer. The meter attempted to calculate nitrogen absorption based on dive time and depth. This was done mechanically instead of electronically, and without the benefit of any actual computing. The Automatic Decompression Meter was introduced just a year after ScubaPro’s most successful product – the ScubaPro Jet Fins – which still remain popular today. Used by divers since 1966The ScubaPro Automatic Decompression Meter 1966 in original box Automatic Decompression Meter Number 4323 made in Italydiving, decompression meter, scubapro

The cylindrical cardboard container with lid formerly contained a ventometer, a small simple tool for measuring wind speed. It consisted of a clear tube containing a small diaphragm which had a hole in the bottom for wind to enter. Once the wind entered the tube it pushed up the diaphragm, indicating the rate of velocity. Ventometers were common devices that have since been replaced by more sophisticated measuring equipment, such as digital air speed meters. Further information on this particular example, including perhaps the name of the manufacturer, may survive on the container but this has not been recorded. The small simple tool for measuring wind speed pre-dates the electronic devices at Gabo Island.Tubed shaped cardboard container with lid to house instrument for measuring.

A small booklet issued by the Australian Post Office to explain the use of post codes 1967. It outlines how to use a postcode, advice for businesses to ensure their correct use and a list of all the postcodes allocated throughout Australia at that time. Two other booklets are updated lists of postcodes.non-fictionThe use of postcodes was introduced in Australia on Saturday, 1 July 1967 by the Postmaster General's department. They are used to more efficiently sort and route mail within AUstralia. In July 1967, the first edition of the Postcode Booklet was distributed free by mail to every Australian household and business address. A total of 4.5 million booklets were distributed, as well as a postcard identifying the recipient’s own postcode. Originally the four digit postcodes were developed for electronic mail handling equipment at the former Redfern Mail Exchange in Sydney. This was extended to cover all locations in Australia and continues to grow as new residential areas are developed.australian mail services, australia post, postcodes

This is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.
