Samples of crystals used in the development of ASDIC transducers, 1917-1918
Samples of crystals, probably quartz piezoelectric crystals, used by Canadian physicist Albert B. Wood in the development of transducers for ASDIC, a prototype active sound detection system later known as SONAR, developed by the British Admiralty and Royal Navy in 1917. This was a key part of research into the hydrophone, a method of underwater detection to combat the German U-boat threat during the First World War. These crystals were associated with the work of Albert B. Wood at the Admiralty Research Laboratory at Teddington, London. The ASDIC hydrophone consisted of an electronic sound transmitter and receiver housed in a metal dome beneath the ship's hull or sometimes towed behind the ship. High-frequency beams - audible 'pings' - were sent out and bounced back when they hit a submarine. The time that passed before an echo was received showed the range of the submarine. The pitch of the echo revealed if it was approaching or moving away. A highly trained operator was required to use the equipment effectively.

Hansen's Writing Ball, also known as Malling-Hansen Writing Ball
Printing & Writing
Malling Hansen Writing Ball, patented in 1865, of about 1875, a typewriter with keys radiating to a common printing point. The Malling Hansen “writing ball” displayed all the significant refinements of writing machines introduced 40-50 years later: automatic carriage return and line spacing, a space bar, a bell to signal the end of the line, provision for carbon paper copies, a ribbon reverse and — most significant of all — visible writing by raising the typing mechanism. The main component of the writing ball is a hemisphere of 54 spring-loaded and engraved alpha-numeric typebars supported on three nickel plated columns with set-screw adjustment and geared mechanism. Each of the fifty-four typebars is aligned at a different angle, yet all converge on the paper at a common point.
