Book - Book - Exercise, E J Barker: Footscray Technical School Diploma Course; Exercise Books for 1942, 1943, 1944
... diploma of electrical engineering... in Electrical Engineering and Mechanical Engineering - three year course... in Electrical Engineering and Mechanical Engineering - three year course ...Collection of exercise books used by E J (Jack) Barker when he attended Footscray Technical School. He studied Diplomas in Electrical Engineering and Mechanical Engineering - three year course - 1942-1944. Prior to this he had attended Williamstown North State School then Williamstown High School. He changed to Footscray Technical School as he was less interested in the academic subjects and more interested in technical subjects. He chose Engineering as it gave access to Diploma Courses and tertiary studies. This enabled him to enter the University of Melbourne and do a Bachelor in Mechanical Engineering - 1945, 1946, and 1947. In 1948 he did a Diploma in Education at Melbourne University. From this path he was able to follow a career in teaching and his first appointment was at the School of Mines in Ballarat, (SMB) 1949. He became the first Vice Principal of SMB in 1960 and then Principal in 1964 to 1976. From 1976 to his retirement in 1987, he was the Foundation Director of Ballarat College of Advanced Education (BCAE). The Library building at Mount Helen Campus is named after him.Lined and Graph exercise books. 1942 - 12 books 1943 - 11 books 1944 - 14 booksBooks labeled with subject name. e j barker, jack barker, footscray technical school, melbourne university, williamstown north state school, williamstown high school, engineering, diploma of mechanical engineering, diploma of electrical engineering, school of mines ballarat, smb, diploma in education, vice principal, principal, foundation director, ballarat college of advanced education, bcae, bachelor of mechanical engineering, library, mount helen campus -

Case leather
... tag riveted onto the top lid "ELECTRICAL ENGINEERING SECTION... parameters are set so that if there is an electrical fault ...This case was used between 1950 and 1980's. As part of the Occupation, Health and Safety requirements, equipment used to monitor the performance of electricity producing generators, regularly, hand held testers were used to check the insulation and the "earth" pin were up the the required operational levels. As the generators and their ancillary monitoring equipment was spread over a large area and cumbersome to service small hand held devices were required. These had to always be safe for the user to operate. A selected range of high quality meters were recalibrated every two years in the Meter and Calibration Laboratory at Yarraville(near Melbourne)This leather case contains a meter which is very significant to The Kiewa Hydro Electricity Scheme because it was an integral part of maintaining the electricity producing water driven generators of the power stations. The reason why this meter was so essential is that provided the safety check on equipment used to monitor each Hydro Generator that they were complying within the grid network parameters. Grid parameters are set so that if there is an electrical fault on the system, that fault can be attended to with a very small change in the output stability of each generator. It is essential that the voltage of the network remain within the set limits. Generators are at Dartmouth, Mackay, Clover, West Kiewa, Yarrawonga, Cain Curran and three Power Stations in the Thornton area.This carry case is made from leather hide and cloth covered cardboard insert. The front side has a lockable English made suitcase fitting. It has a broken carry strap (leather) travelling from top and through leather strap holders both sides and on the bottom of the case.
