  • Composite biomaterial including anisometric calcium phosphate reinforcement particles and related methods
    Patent number: 7758882
    Abstract: Composite biomaterials (e.g., for use as orthopedic implants), as well as methods of preparing composite biomaterials, are disclosed. The composite biomaterial includes a matrix (e.g., a continuous phase) comprising a thermoplastic, a calcium phosphate composition that is curable in vivo, or combinations thereof. The composite biomaterial also includes an isometric calcium phosphate reinforcement particles which are dispersed within the matrix.
    Type: Grant

  • Multi-mode missile seeker with adjunct sensor blocking an electronically scanned radio frequency aperture using an off-boresight direction finding process
    Patent number: 5486831
    Abstract: A multi-mode seeker which comprises a stationary antenna and electronic circuitry responsive to signals received by the antenna to cause the antenna to scan a field of view determined by the signals received by the antenna. The seeker has a nose region positioned at the forward portion thereof and an adjunct sensor disposed in the nose region ahead of the antenna. The electronic circuitry includes circuitry for performing a Sum/Delta monopulse processing technique on the signals received by the antenna the Sum/Delta monopulse processing including calculating each of a standard Sum signal, Delta-Azimuth signal and Delta-Elevation signal. The seeker has a boresight axis, the center of the field of view being off boresight, in general. The seeker has a field of regard, the field of regard having plural sectors, each of the sectors having separate predefined compensation.

  • Internal combustion engine
    Patent number: 3930471
    Abstract: A torch ignition engine of reduced complexity and including novel arrangements of the cylinder heads and manifolds. Specific features of a preferred embodiment include auxiliary ignition chambers formed by cup shaped inserts retained in place by the spark plugs, auxiliary intake valves actuated directly by tappets mounted on the spring seats of the main intake valves, and auxiliary induction passages extending internally of the intake manifold, cylinder heads and exhaust manifolds where they extend in heat exchange relation with various exhaust gas passages.
