  • Patent number: 4431147
    Abstract: A steerable artillery projectile utilizing electro-optical circuitry to home on a laser designated target where the rear end of the projectile is displaceably coupled to the front end thereof which contains the electro-optical circuitry and munitions is disclosed. The displaceably coupled rear end of the projectile has a plurality of compartments equispaced around its longitudinal axis and each compartment has a gas cartridge which can be activated by the electro-optical circuitry. In flight, a selected gas cartridge may be discharged by the electro-optical circuitry causing the longitudinal axis of the rear end of the projectile to momentarily move out of line with the longitudinal axis of the front end of the projectile resulting in a modification of the flight path of the projectile to home on the laser designated target.

  • Patent number: 4413949
    Abstract: A turbine blade for a gas turbine engine has a hollow aerofoil and a root. A first insert for the distribution of cooling air in the aerofoil is inserted thereinto through an opening in the root but due to the relatively high camber of the blade the insert is such that it has to be displaced laterally after insertion. A second insert, also inserted through the opening, is provided to secure the first insert in position and to guide the cooling air from the opening to the first insert.

  • Patent number: 4407180
    Abstract: The present load lock secures loads, such as containers, or weapons, such bombs, to an aircraft thereby using a single or multiple point suspension system while simultaneously clawing or clamping the load to prevent it from undesired movements. The clawing or clamping is accomplished by the same centrally located mechanism which is operated manually or by an electric drive, whereby operation in one direction results in clawing while operation in the opposite direction results in clamping. In both instances the force causing the clamping or clawing is adjustable as a biasing force. The suspension of the load is accomplished by a power operated hook reaching into an eye of the load. The arming or fuzing of a weapon held in the lock is accomplished by a mechanism arranged laterally in the lock housing for easy access.

  • Patent number: 4395935
    Abstract: An improved receiver assembly adapted for use in a weapon that fires cartridges fed into the same from an ammunition belt having metal links. The assembly includes a trunnion block having a surface and two oppositely disposed sides. The surface is delimited on two opposed sides thereof by retaining means formed along said edges of the trunnion block. A wear plate is adapted to removably overlie the surface, and absorbs contact from the metal links. The wear plate is planar, being made of hardened spring metal, preferably steel, type AlSl C 1045, hardened to R.sub.c 48-52. Two opposed edges of the wear plate have fastening means, preferably in the form of C-shaped flanges. These resiliently grip the retaining means to coact therewith in securing the wear plate to the trunnion block. A manually manipulatable tongue is formed on one of the flanges of the wear plate to facilitate placement and removal of the same.
