Abstract:
A missile system in which a missile is guided in a predetermined trajectoryrom launch or shortly thereafter in yaw by proportional navigation and in pitch first by a pitch programmer until said missile reaches a predetermined angle between a line of sight of a seeker of the missile and a centerline of the missile, then in pitch by a time optimal controller to direct the missile at a predetermined angle toward a target and finally by proportional navigation in pitch of the missile to the target.
Abstract:
In a missile system, a simple way to guide a missile in a predetermined tectory from launch to the impacting with a target for optimum warhead penetration of armor by a guided missile. Initially, the missile is guided in yaw by proportional navigation. Subsequently it is guided in pitch first by a pitch programmer until the missile reaches a predetermined gimbal angle between a line of sight of a seeker of the missile and a centerline of the missile, then in pitch by a pseudo-time-optimal closed loop controller to direct the missile pitch attitude at a predetermined rate toward a target until said missile reaches another predetermined gimbal angle, and finally by proportional navigation in pitch of the missile to the target.
Abstract:
A feedback PDM encoder and method is presented which permits utilization ofneumatic pulse duration modulation (PDM) actuators with potentiometer position pickoffs in a digital autopilot loop. The actuator is directly driven by a signal derived in the digital autopilot which is in the pulse duration modulation (PDM) format. This signal is derived within the autopilot digital computer using conventional digital techniques. Analog feedback from the potentiometer which indicates angular excursion of the actuator is formatted into a PDM format. This method yields all signals necessary to operate the actuator in a closed loop missile control system.
Abstract:
Apparatus and method of anti-armor missile trajectory shaping for optimum rhead penetration of armor by a guided missile. The guidance system utilizes a terminal homing guidance unit in conjunction with a programmed control signal through the missile's autopilot to cause the missile to cruise at low altitudes and then dive onto the armor target. The terminal dive angle can be selected dependent upon the target's armor characteristics.
Abstract:
A bracket for mounting components in a housing in which a first set of two legs extend from and substantially perpendicular to one surface of a plate and a second set of at least two legs extend from and perpendicular to the opposite surface of the plate. The bracket is connectable to the floor of the housing to support a first component at a predetermined height in said housing and is reversible to support a component of a greater height than the first component.
Abstract:
A method of treating polycystic kidney disease in a subject comprises administering to the subject an effective amount of a compound represented by Structural Formula (1): or a pharmaceutically acceptable salt thereof.
Abstract:
Method of treating autoimmune conditions are disclosed comprising administering to a mammalian subject IL-12 or an IL-12 antagonist. In certain preferred embodiments the autoimmune condition is one which is promoted by an increase in levels of IFN-γ or TNF-α. Suitable conditions for treatment include multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, autoimmune pulmonary inflammation, Guillain-Barre syndrome, autoimmune thyroiditis, insulin dependent diabetes melitis and autoimmune inflammatory eye disease.

Abstract:
A missile using fluidic sensors for determination of net aerodynamic forcend moment on the missile. The force and moment thus determined are processed and summed by fluidic amplifiers and integrators to provide control signals for fluidic thrusters or other steerers for the missile. The sensors are diametrically opposed pairs of pressure taps located axially and circumferentially in the missile skin. Net aerodynamic force on the missile is taken as the algebraic sum from all the sensors in a linear fluidic summer, and net aerodynamic moment is taken from the proportional sum of the sensors in accordance with their position along the axis of the missile. This proportional sum is made in a fluidic vortex summer.
