Abstract: A platform stabilization system utilizing a small free running gyro, gimballed to the platform, as the reference element. Optical means are used to generate error signals in a torque free subsystem for sensing misalignment between the reference gyro and the platform. A system of magnetic rods and surrounding electrical solenoid coils are used to initially position the reference gyro. The reference gyro to platform gimbals are located within the structure of a second gimbal system mounting the platform to a pedestal mount. The close spacing of the axes from the platform yields a minimum swept volume of the pedestal in operation. Torque motors located in the pedestal are coupled to the platform gimbal by means of flexible cables. The motors are controlled by amplified signals from the optical error sensor signals. The result of this design is an extremely compact, high speed, low mass, low cost, stabilized platform system.

Abstract: A mirror or other target-sight element in a military vehicle is subject to oticeable vibration or dislocation relative to inertial space as the vehicle moves over rough terrain. To prevent such vibration or dislocation the mirror is driven by a torque motor that is controlled by a gyroscope that mechanically senses these mirror dislocations. The demodulated gyroscope output signal is amplified and applied to the torque motor, which thereby makes the correct repositionment of the mirror to keep the reflected image in a generally stable position in spite of terrain disturbances. The present invention contemplates a second gyroscope also responsive to vehicle pitch movements. The demodulated output signal of this second gyroscope is applied to a zero cross over detector, which produces a square wave output signal substantially in phase with the signal from the first gyroscope.

Abstract: A protective cover system for use in connection with guiding paths of machine tools including a plurality of overlapping cover plates telescopically moved into and out of each other while each cover plate at its front end face rests on the guiding path and at the rear end rests on the next segmental cover plate.

Relative movement between the cylinder and the pertaining cam segment is brought about by fork-shaped rods linked with the arms of said fork-shaped rods to the front end faces of the cover plates.

Abstract: A control lever assembly for controlled reciprocation of an operating member which may be a Bowden cable for regulating the flow rate of a pump supplying a hydraulic motor in a hydrostatic transmission. In addition to the usual pivotally mounted control lever, an intermediate lever is pivotally connected between the control lever and the operating member. The intermediate lever is received in a sleeve member which is pivotally mounted about a fixed axis spaced from the fixed axis about which the control lever pivots. The sensitivity of the control lever assembly is thus made smoother and more gradual proximate to the neutral or dead center position of the assembly.

Abstract: Gyroscope instrumentation for providing stabilization of the direction of a ine-of-sight of more than 45.degree. about one or more axes is described utilizing a two axes optical system. An inner gimbal supports a gyro rotor and a first mirror diagonal with a clearance window to admit light. The gyro rotor keeps the first mirror aligned in a fixed direction relative to an inner gimbal axis. The inner gimbal is supported by an outer gimbal. The outer gimbal has a second mirror mounted on it. The gyro rotor keeps the second mirror aligned with the outer gimbal axis. The net effect is that the optical axis at the input has a fixed orientation in space and the optical axis at the output axis has a fixed orientation relative to a platform on which the system is mounted.

Abstract: A remote control apparatus for varying engine speeds includes a housing and a reversible constant-speed electric motor mounted on the housing, the motor being adapted to drive a pulley at a substantially lower rotational speed through speed reducing gears disposed in the housing. A pair of stops are adjustably mounted on opposite sides of the pulley for stopping the motor upon contact with a pendulum member after a predetermined rotation of the pulley in either direction. A chain attached at one end to the pulley is attachable at its other end to a spring-biased throttle rod of an engine or the like, the chain being wound around the pulley upon rotation of the motor to exert a pull upon the throttle rod and increase the speed of the engine. Rotation of the pulley sufficiently to cause a stop to actuate the pendulum member causes the motor to stop, thereby maintaining the engine speed at a predetermined maximum.

Abstract: A flowmeter and a function generator which may be employed separately or as an integral part of the flowmeter. A differential pressure unit (DPU) is connected to a pipeline on opposite sides of an orifice plate therein. The DPU produces an input shaft rotation directly proportional to the differential pressure. A linkage mechanism is then moved by the input shaft. The air relay produces an outlet air pressure which is substantially a curvilinear function (square root, for example) of the input shaft rotation. The curvilinear function is generated by the use of the linkage mechanism which includes plural fulcrums. These fulcrums are fixed to the air relay output shaft. A lever supported usually on each fulcrum in succession rocks on each successive fulcrum.
