Abstract: Systems and methods for automatically delivering a dose of pharmaceutical liquid to an animal includes electronic control to automatically obtain dose information for the animal, electronic control to deliver a volume of pharmaceutical liquid to the animal in response to the dose information; and automatically recording a detailed audit trail of the liquid delivery to the animal. The dose information may be a function of a stored value of at least one physical parameter of the animal. The detailed audit trail may include, for example, information about the amount of liquid actually delivered to the animal, specifying the time of delivery, whether there were any problems with the delivery, and if so, information about such.

Abstract: A torquer system for a gyro device that has a spherically shaped rotor divided into upper and lower hemispheres. The rotor of the gyro is mounted on a gas bearing over a spherically shaped stator and supports an optical assembly positioned parallel to the spin axis of the gyro. The torquer is positioned on the base of the gyro beneath the lower hemisphere of the rotor so as to permit the maximum angular freedom of the rotor and optical assembly. The torquer comprises four pole pieces separated 90.degree. from each other. Each torquer has two pole faces and coils located between pole faces. The coils contain separate windings for bias and control of the torquer. A current flow through the windings of the torquers causes magnetic flux lines emanating from the pole faces to pass through magnetically permeable material affixed to the lower hemisphere of the gyro rotor closing the magnetic circuit.

Abstract: In an accelerometer in which a proof mass is disposed in a damping fluid and acts against said fluid through a flow path controlled by the groove length of a helix disposed on a bellows, a low resistance flow path is provided connecting the areas above and below the helix to prevent movement of the proof mass due to fluid displacement caused by rapid temperature changes.

Abstract: A gyro seeker which may be employed and housed in the nose section of a cannon launched missile. The gyro seeker functions in a dual mode in that it detects either laser designated targets or targets emitting infrared radiation. Structurally, the gyro seeker comprises a spherically shaped gyro element hydrostatically supported on a gas bearing surface within a spherical cavity of a spherically shaped platform. The gyro in turn supports optical and detector/cryostat assemblies for tracking and detecting desired targets. The platform is similarly hydrostatically supported on gas bearings within the housing. The platform is restrained on the base of the missile by a trapeze mechanism which limits the platform to two-degrees-of-freedom. Means are provided for torquing both the gyro and the platform. Additional means are provided to allow the gyro seeker to withstand the high induced acceleration forces of cannon launching.
