Abstract
1, 247, 127. Depth gauge. C. ALINARI. March 18, 1970 [March 20, 1969], No.13105/70. Heading G1L. A depth gauge comprises a pointer 6 moved across a scale 7 by a mechanism 5 controlled by the movements of an elastically deformable metal disc 3 with its edge resting freely upon an annular seat 2 in a casing 1, the whole being enclosed with in a sealed outer case 9 having a transparent window 10 for viewing the scale and a flexible easily deformable wall 8 placed over and in contact with the disc 3 to transmit to the disc an ambient pressure corresponding to the depth to be measured. Preferably the disc is of spring steel. The interior space 12 of the gauge may be evacuated to eliminate the effect of temperature. Outer case 9 may be provided with means for attaching the gauge to a wrist.
