serves to reduce oscillations. It is reported that this design compass

years, there has been a consolidation of British instrument makers and
the firm of Henry Browne & Son has changed hands a number of
times. At last count, it became part of Lilley &

this aim an hour glass. The traverse board featured hence the

Via a magnetic needle
remote-controlled model submarines
Helmut Huhn and Heinrich Kistenich have developed a batch of
remote-controlled model submarines steered by means of a compass
needle. The inventors placed a cheap pocket compass' magnetic needle
inside a voltmeter's coil frame rotated by means of a remote-controlled
servo-motor to set the ship's course. The needle's rotation is limited
by two lateral stops. Located above the needle's north end, an LED
casts its shadow onto two phototransistors (s. pics below). As long as
the latters receive a differential amount of light they activate the
ship's propellers until the hull is on course and the needle exactly
between the phototransistors.
