As shown in Fig. 1, the tilt-detector comprises a pair of thin tungsten or platinum resistance wires 3, 4, resiliently supported in V formation by the common terminal 7 and the side supports 5, 6, carried by the base 2. The wires 3, 4 are enclosed in an envelope 10, filled with helium, neon, argon, krypton, xenon, or nitrogen, which may be at a pressure of one atmosphere. The base 2 may be attached by a bayonet joint to a socket 18 which is provided with three spring plates 23 to engage conductors 8 leading to the three terminals 5, 6, 7. Fig. 9 shows a modified arrangement of wires and envelope. In a further modification, the wires are mounted in separate envelopes which may be plugged into a common support at the appropriate angle. When used to control a gyro vertical 32, Fig. 4, a detector 1 is secured by the grub-screw 26, Fig. 1, to a fore-and-aft trunnion 30 of the gimbal 28, and a second detector 1a is secured to a trunnion 34 which supports the rotor casing for rotation about a transverse axis in the gimbal 28. The resistances in detector 1 are connected in a Wheatstone bridge which controls, through an amplifier and either a relay and direct current torque motor, 68, 76, or a two-phase torque motor (see Group XXXV), the application of correcting torques about the transverse axis 33, 34. The detector 1a similarly controls the application of correcting torques about the fore-and-aft axis 29, 30. In a modification the gyroscope 32 is dispensed with and replaced by a shaft which carries a detector responsive to tilting about a transverse axis and controlling a motor for restoring the shaft about the transverse axis. A second detector responsive to tilting about the fore- and-aft axis is carried by a fore-and-aft trunnion of the gimbal in which the shaft is mounted and controls a motor for restoring the gimbal about the fore-and-aft axis. A horizon bar may be fixed to the shaft and read in conjunction with a disc secured to the gimbal. The detector may be used for maintaining the rotor axis of a directional gyroscope horizontal. Specification 604,557 is referred to.
