Abstract: The Dragless Flight Control System for Flying Objects utilizes paired fins that are mounted to rotate in opposite directions. When no lift is desired during the object's flight, the fins are completely retracted into their housings that are recessed into the body of the object. This minimizes the drag. The fins are set to a maximum no-stall angle relative to the body axis of the flying object. To provide lift and other flight controls, such as roll and yaw, the fins are selectively exposed outside the exterior skin of the flying object by being rotated on their axes, the two fins in a pair always being rotated in opposite directions. Varying the amount of exposed area of the counter-rotating fins can generate lift effect that is proportional to the exposed area and similar to that produced by the current, permanently-extended standard rotational fins.

Abstract: The Rotational Canted-Joint Missile (RCJM) Control System utilizes a single or multiple body joints that rotate in planes that are not perpendicular to the missile body axis. The result is the deflection of a portion of the missile body for flight control purposes. The canted interface plane between any two adjacent movable sections of the missile body and a joint at the interface plane that allows one of the sections to be rotated by a pre-determined angle with respect to the other section comprise a rotational plane mechanism that offers an inclined bearing plane with a large mechanical advantage over typical “brute force” ball joint methods.

Abstract: The Magnetostrictive Missile Guidance System pivots the missile nosecone about a multi-directional joint on the missile axis to produce aerodynamic control forces for missile flight path control. The nosecone is driven by magnetostrictive materials in conjunction with displacement amplification devices. The determination of the nosecone deflection angle necessary to achieve any change in the flight path is made by a sensing device that produces position signals and a guidance computer that produces the desired flight path command signals. The sensing device senses the current position of the nosecone and this position signal is compared with the command signal by the computer to yield an error signal, which is indicative of the difference between the two input signals. Then appropriate magnetic field is applied to the magnetostrictive materials to cause them to grow in length and deflect the nosecone until the error signal is eliminated and flight path is changed.

Abstract: An oil pressure transducer with an improved composite base portion for mounting the transducer to a vehicle engine or the like to receive pressurized oil. The composite base has a skeletal component with a particularly effective configuration to permit sealing with an encircling molded elastomeric portion. In this manner, a highly leak resistant transducer base is produced having a metal portion for convenient threading into a threaded aperture of a vehicle engine and having an elastomeric portion adapted for ready attachment to a remaining portion of the transducer.

Abstract: An improved electronic oil pressure transducer with a circuit board supporting a power transistor and with a metal heat sink attached to the transducer so that a portion thereof extends through an aperture in the transducer housing and into intimate contact with the power transistor to transfer heat from the transistor to the atmosphere.

Abstract: A transducer for sensing fluid pressure including an enclosure forming housing, a cup-shaped rubber-like mount having an end wall and an annular side wall for supporting a pressure sensing electronic chip against the inner end wall surface of the mount. The chip is supported against the end wall in covering relation to a small opening in the end wall which connects one side of the chip with atmospheric pressure. A layer of non-hardening sealant gel extending between the inner side wall surface completely covers the chip and transmits fluid pressure to a second surface of the chip but inhibits fluid contact and leakage past the chip.

Abstract: A liquid fluid level sensor responds to differential pressure forces exerted on a diaphragm as produced by exposure of liquid fluid to one side and of atmosphere to the other side. An arched resistance card is movable with the diaphragm to engage the mid-portion of a metal spring which progressively overlies greater portions of the card as the diaphragm moves thereby changing the resistance of a circuit including the card and the spring.

Abstract: A vehicle fuel tank with a fuel level sensor is disclosed including a housing rotatably supporting a molded crank arm and a pivotal float rod attached thereto. The crank arm has a bore for insertion of one end of the crank arm and an apertured metal insert molded therein for providing a gripping interference fit between the inserted rod and the crank arm.

Abstract: A combination fuel delivery, pick-up and fuel level sensor of the type including conduits at least one of which is formed in a helix configuration so as to locate and bias the inlet closely adjacent the fuel tank bottom irrespective of differences in the depth dimension of associated fuel tanks.
