Patent number: 4181103Abstract: A monitor connected to an automotive engine, suitably monitoring pulses in the ignition system thereof electronically, and a flyball-type governor connected to the final drive train of an automotive engine transmission driven thereby, respectively operate switches for independently causing an engine-throttle-closing fixed-rate drive to run in throttle-closing direction to override the manual throttle control whenever the engine exceeds a predetermined engine speed or the vehicle approaches or exceeds a predetermined vehicle speed. Whenever both engine and vehicle are below their respective predetermined speeds and the vehicle speed is neither constant nor accelerating in the aforementioned approach range, the unoperated switches cause the throttle drive to run in throttle-opening direction to allow, but not to cause, full-throttle operation, which may be achieved by operating the manual throttle control to open the throttle to obtain full power.Type: GrantFiled: May 6, 1977Date of Patent: January 1, 1980Assignee: Sturdy Truck Equipment, Inc.Inventor: Harry D.

Patent number: 4178871Abstract: A control system for hydrofoil craft is one in which control surfaces are moved automatically in response to signals derived from the motion of the craft to stabilize and control the craft. In such systems, a potentially dangerous condition can occur in case of a failure or malfunction in the roll control system. In order to prevent such conditions, two redundant roll sensing devices are provided which normally generate identical signals to actuate the control surfaces to stabilize the rolling motion. In case of a failure or malfunction, the signals provided by the two sensing devices become different. When this occurs, all normal control signals to the control surfaces are terminated; and secondary feedback loops act to position all control surfaces to smoothly land the craft.Type: GrantFiled: January 23, 1974Date of Patent: December 18, 1979Assignee: The Boeing CompanyInventor: Irving A.

Patent number: 4176814Abstract: An apparatus for correcting the terminal portion of the ballistic trajectory of a projectile. The projectile is initially fired at a target in a manner to cause the projectile to rotate in flight. At least one detector is mounted on a front surface of the rotating projectile to rotate with the projectile and scan the target area in a spiral pattern. A laser beam is directed to hit the target and a reflected portion of the beam energizes the scanning detector. The energized detector transmits an ignition signal to activate a trajectory correction motor and an associated nozzle having a plug that is weakened in response to the signal. The activated motor operates during the terminal portion of the trajectory to generate a thrust pulse that is passed through the nozzle having the weakened plug. The thrust pulse is directed by the nozzle to correct the trajectory of the projectile.Type: GrantFiled: March 11, 1977Date of Patent: December 4, 1979Assignee: AB BoforsInventors: Kjell A.

Patent number: 4160417Abstract: The system of the present invention basically consists of a detector unit unted in each bomb or airborne weapon and operable upon interception of a signal emitted by an aircraft-mounted source. The required signal for arming is present only in a well defined zone below the aircraft and only in response to pilot command during weapon release. The signal consists of an unmodulated beam of high-energy photons (gamma rays) emitted by a radioisotope source on the aircraft. The weapon must fall well below the aircraft to see the signal. Geiger-Mueller tubes are used for radiation detectors and the resulting signal is processed to initiate the arming or fusing sequence. Power for the operation of the detector and associated electronics is transferred through the metallic covering of the weapon by means of a split-core transformer at the time of release.Type: GrantFiled: April 29, 1969Date of Patent: July 10, 1979Assignee: The United States of America as represented by the Secretary of the NavyInventor: Ronald J.
