106637 106637 2014.0018.001 Spacecraft model Yellow-bronze coloured spherical mass [possibly mahogany wood with synthetic coating] has multiple "nodes" protruding from coffered panelled surface; mounted by means of silver metal post to round dark wood base. Cavorite Sphere   Unknown Philippines   Manila 2014       1 Yellow-bronze coloured spherical mass [possibly mahogany wood with synthetic coating] has multiple "nodes" protruding from coffered panelled surface; mounted by means of silver metal post to round dark wood base; black synthetic pads on underside of base. Representative model of imaginary and futuristic (for 1901 that is) spacecraft and demonstrates the creativity in early thoughts about space travel and exploration. There is no Canadian context as such but H.G. Wells¬í book First Men in the Moon (1901) and the movie by the same title (1964) will be familiar to some Canadians. [Ref. 1] Small scale replica of three-dimensional object created for display purposes. The model has no real technical significance as it is constructed of wood but is representative of imaginary technology and the ways in which people have conceived of flight and spaceflight before it became a reality.

Unknown     1900 1950 between   1 Reddish black wooden mallet with red synthetic stamp with embossed print. Paper label covered in clear synthetic. Taken from acquisition proposal Reference 1: Through the Bithell story we see the cohesiveness of Montreal¬ís English-speaking enclaves at the turn of the 20th century. Joseph Bithell¬ís first store was located on Beaver Hall Hill at the outer edge of the ¬ìSquare Mile ¬î the home of Montreal¬ís Anglophone elite who headed many of Canada¬ís major businesses and institutions. His clientele most likely included many of the area¬ís residents who as Margaret Westley notes preferred to ¬ìshop at stores owned and operated by fellow Scots and Englishmen¬î and who¬ís favourite past time included horse riding horse driving polo and frequenting the Montreal Hunt Club. The relocation of their various businesses across the city also reflected this cohesion as they tended to set up their shops in or in close proximity to these Anglophone enclaves. The story tells us about Montreal at a time when it was the industrial and commercial centre of Canada and from the perspective of skilled tradesmen who worked in what was quickly becoming a dying trade. The adoption of the automobile redefined personal transportation as its increasing popularity began reducing the need for horses and buggies and consequently the need for saddle and harness makers. In this way the Bithells were part of an important aspect of Canada¬ís economical social and cultural history. Used to imprint the words embossed on the stamp on another surface. Taken from acquisition proposal Reference 1: In the 1850s many industries started to transition from craft production to small-scale manufacturing to mechanized industry which saw the use of heavy costly machinery rather than smaller hand tools. At this time Montreal¬ís leather industry was starting to grow exponentially and by the 1890s the Montreal market for leather goods was considered one of the largest in Canada dominated largely by shoe production. At this time the leather industry consisted of different modes of production that co-existed. The most predominant were artisanal production ¬ìputting-out¬î where men and women did stitching work from home and factory production. Leather production in artisanal shops such as those in Montreal¬ís tanning district of Saint Henri started to give way to ¬ìputting out¬î by the 1850s. In the shoe industry both ¬ìputting out¬î and artisanal shoemaking were in decline by the 1870s replaced by factory or mechanized production. Montreal had dominated Canadian saddle production in particular with an estimated 23 mostly small and artisanal saddle manufacturers in 1871. The situation changed very little in 1881 as the industry was described as being ¬ìstocked with workman.¬î Gregory Kealey notes that harness and saddle making were less affected by mechanization than other trades such as shoemaking which could explain the relative success of the trade at this time. Saddlery and harness making were also considered prestigious trades compared to other forms of leather work because of the time required to learn and master the trade. By the 1920s Montreal had begun to loose its status as a preeminent manufacturing centre in Quebec and Canada. Saddle making also began to die off and most of what was left of the industry was centred in Ontario. Nonetheless by the end of the Second World War the leather industry along with food clothing textile wood and tobacco made up 54.2 per cent of Quebec¬ís industrial labour force and 48.6 percent of the total value of ind… Industrial Technology Tools & equipment-trades Harness & saddle maker Industrial Technology Tools & equipment-trades Leather worker       wood;synthetic;paper 8.1 5.7 2.6       http://source.techno-science.ca/artifacts-artefacts/images/2010.0704.001.aa.cs.png http://source.techno-science.ca/artifacts-artefacts/images/2010.0704.001.aa.cs.thumb.png

United States of America New york Williamsville 1971   circa   2 brown stained and coated wood casing/ white and black keys/ charcoal coloured synthetic control panels with black synthetic and brushed metal control knobs/ blue red white black synthetic switches/ brown power cord Part of a collection of electronic equipment for musical composition performance and recording owned and used by Canadian Paul Hoffert composer musician author researcher entrepreneur and arts administrator. American born he came to Canada as a child and his career has encompassed many areas of the Canadian music business including working as a jazz pianist CBC music director and performer educator manufacturer of stereo equipment music producer and film composer. In the late 1960s he worked for a short time as a researcher in Hugh LeCaine's electronic music lab at NRC where he wrote a computer program for music analysis and developed a solid-body electric violin. In 1968 Hoffert and rock drummer Skip Prokop formed the very successful jazz-rock band Lighthouse (1969-1974 1982 1993-present) which earned one platinum record and four gold records and received three Juno awards between 1971 and 1973 In 1977 Hoffert received a Canadian Film Award (later known as a Genie) for best original musical score for the movie "Outrageous!". He also headed the Academy of Canadian Cinema and Television the Guild of Canadian Film and Television Composers and the Ontario Council for the Art. In 1995 he was inducted into the Canadian Rock and Roll Hall of Fame. In 2009 he was appointed a Member of the Order of Canada. An instrument which makes musical tones by electronic synthesis and plays these tones by means of a keyboard. The Hoffert collection consists of approximately 25 pieces of electronic equipment for musical composition performance and recording. These range from iconic keyboard instruments of the 1970s to a variety of digital devices from the 1980s to computer software from the early 1990s. These were used either for stage performances especially during his years in the jazz rock band Lighthouse or for work in his home studio. The Minimoog Model D has been called the first synthesizer ever to become a "classic." (Pinch & Trocco p. 214) One of the first portable keyboard synthesizers the Model D was the only Minimoog put into production. Before 1970 synthesizers were generally massive modular devices in which musicians programmed a huge range of sounds by using patch cords to connect the various modules (e.g. oscillators amplifiers filters envelope generators) that generated and modified the electrical signal that drove the loudspeaker(s). These were essentially studio instruments ill-suited to live performance and the itinerant life of a touring musician. Hugh LeCaine's Electronic Sackbut (1948) had been a more promising attempt at a performance instrument but efforts to commercialize an updated prototype of the Electronic Sackbut in 1970-71 failed. Though not nearly as versatile as the "monster Moogs" of the late 1960s the Minimoog incorporated a number of modules in a single cabinet which the musician controlled with knobs switches and wheels to make adjustments to the sound output in real time. By the time the Minimoog was introduced in 1971 the Moog brand name had already been lent a great deal of cachet by such recordings as Wendy Carlos' "Switched-On Bach" (1968) and Emerson Lake & Palmer's "Lucky Man" (1970). The Minimoog offered a compact affordable means of emulating some of that distinct Moog sound and it quickly became an icon of the 1970s progressive rock and jazz rock scenes. During its production life between 1970 and 1981 over 12 000 were made. Among the musicians who used Minimoogs were… Communications Music Electronic             wood;synthetic;metal;wood 71.8 43 14.5       http://source.techno-science.ca/artifacts-artefacts/images/2005.0095.001.aa.cs.png http://source.techno-science.ca/artifacts-artefacts/images/2005.0095.001.aa.cs.thumb.png

Before 1949 the Standard Cool White was called 4500 Degrees White to designate colour temperature in degrees Kelvin of a theoretical thermal radiator whose colour is an approximate visual match to the fluorescent lamp.

The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the Canada Science and Technology Museum in 1992 A device used to provide illumination by means of an electric current which excites mercury vapor in a glass tube producing short-wave ultraviolet light that then creates fluorescence producing visible light. Slimline lamp bulbs were first designed in 1945 to add to the elegance of fluorescent lighting systems and eliminate the preheat requirement. Slimline bulbs were instant-start type that required no starter switches and lowered the cost of maintenance. To allow for an instant start the lamp bulb contained a loose overwind of fine (0.7 mil.) tungsten wire added to a coil of modified dimensions. The overwind performed a double function. First it reduced sputtering time by rapidly reaching the emitting temperature when the arc first struck; and second it acted as a 'basket' to hold a large quantity of emission material tightly. When the first lamps of this design were manufactured they were affected by end discolouration. This problem was resolved in 1947 by using a cathode shield made of nickel or iron.
