Scientific & Projections Ltd
Can you help David Read in his quest for information?
My main objective in contacting this STC New Southgate website is to find out :-
I have interesting evidence that in the early 1900s, Scientific & Projections
Ltd were active in researching the field of acoustics and audio transducers.
This was a time when all sorts of strange ideas were being applied to
microphone concepts. An extract from research in this field mentions
Scientific & Projections Ltd as the abstract below shows and
this must have been long before Western Electric UK Ltd (later
Standard Telephones and Cables) became involved with the company.
Before developing the electric amplifier and the loudspeaker, experiments included direct friction drive and compressed air systems - so called Strong Tone Machines such as the Fortophone, Toncyclop or Gigantophon. The enterprise Scientific & Projections' (London) experimented with a Flamephone, at which the gas supply for the burner was modulated by a membrane of the pick-up".
Here are a couple of images of the sort of clock that carried Scientific & Projections Ltd's name:
These clock movements were made for Scientific & Projections by H. Williamson Ltd to a very high standard. They incorporated a chain fuzee to provide constant force to the escapement and used a quite exceptional pendulum based on Gardner's patent for mercurial compensation. See attached images.
It is a puzzle what these clocks were made for. The clock's wheel train carries a bevel gear that must have driven a transmission rod to some sort of equipment external to the clock. My guess would be a chart recorder or inking chronograph. In any event these clocks clearly drove a scientific instrument of some sort rather than being a plain timekeeper.
It is unlikely however that these attached images will trigger
any memories amongst post war STC people because these clock
movements were made for Scientific & Projections
before 1930. Nevertheless, any scrap of memory or knowledge concerning Scientific & Projections
Ltd and also how STC came to be linked to this company would be of great help
