Patent GB-713134-A (GB)
Abstract: 713,134. Indicating-apparatus. BENDIX AVIATION CORPORATION. May 27, 1952 [June 15, 1951], No. 13454/52. Class 106 (4) A dial instrument for indicating variations in either senses from a null value comprises a fixed dial 9, having a pair of arcuate cut-outs 11, 12, a pair of indices associated with the cut-outs, a movable dial 16 mounted behind the fixed dial, and associated with it, an arcuate scale on the movable dial viewable through the cut-outs with the ends of the scale coinciding with the indices when the movable dial is at null position, and means for rotating the movable dial in either direction for viewing the associated scale through only one or the other of the cut-outs. The invention is shown applied to an instrument 5 for transmitting to a control system small increments of angles in either direction from a fixed reference. A fixed dial 9 has three arcuate cut-outs 10, 11 and 12 with a scale 13 round the inner edge of the first and reference lines 14, 15 at the outer and inner edges of the other two respectively. An inner dial 16 rotatable behind the dial 9 has a scale 17 registering. with the cut outs 11, 12 with indicia " 0 " to " 180 " round the inner side of the Scale 17 visible only through the cut out 11 and indicia " 180 " to "0" round the outer side visible only through the cut out 12. An outer dial 18 movable behind the dial 9 has three equi-spaced reference lines forming a scale 19 adapted to register with the cut out 10 to be read against the scale 13. The required angle is set by a knob which through chains of gearing drives the dials 18 and 16 at different speeds in the ratio of 24:1 thus enabling a course reading from the scale 17 to be combined with a fine reading of the scale 13 to provide an accurate indication of the angle set on one side or the other of the zero position. The dial 9 is mounted on a ring secured to posts carried by a base, the dials 16, 18 are secured to concentric shafts connected for rotation by gearing at different ratios of angular speed.

Title: Ultrasonic Apparatus for Locating Interfaces in Media
IPC: G01S15/32
Filed: 1980-02-15
Abstract: Apparatus to detect and/or locate an inhomogeneity in a medium comprises a transducer (1) to transmit frequency-modulated ultrasonic energy through the medium and a transducer (3) to receive reflected energy. The transducers are connected to a phase-locked loop (11, 12) which maintains a required relationship between the phase of the transmitted modulation and the phase of the received modulation by adjustment of the modulation frequency. The modulation frequency adjustment is kept within predetermined upper and lower frequency limits so that the loop can lock only on to received ultrasonic energy which has travelled a distance within a predetermined region in the medium. The energy may be scanned across the region to produce a profile of the inhomogeneity, such as tissue (40) at a certain depth within a limb (42). The invention may also be used to detect the level of water or sediment (37) at the bottom of an oil tank. <IMAGE>
