Title: Missile guidance roll reference - is obtained from earth's magnetic field using three detector coils and launcher magnetometer
Inventor: CLAUSIN PIERRE
IPC: G05D1/08
Filed: 1975-08-04
Abstract: The automatic guidance system for a projectile, missile or aircraft obtaining a roll reference from the earths magnetic field. A detector coil, field gradient detector coil and a pitch detector coil are located in the rear of a missile. Pitch signals received from the detector coil (1) are eliminated and a detector determines only the roll signal. A magnetometer on the launcher provides a correction signal determined by the vertical axis and earths field. This data is stored and given a constant phase shift to produce the roll reference signal. A detector connected to an inhibitor prevents this in presence of a non uniform field.

Title: Surface coating of copper alloys - where surface of alpha phase workpiece is converted to beta phase by diffusion heat treatment
Inventor: EBERHARDT
IPC: B23K35/00
Filed: 1975-08-14
Abstract: An adherent coating is applied to a metal part, esp. a part made of an alloy existing in two phases, e.g. the alpha and beta phase. The novelty is the clamping together of one part made of the alpha phase and one part made of the beta phase, followed by heating so one phase is transformed into the other phase for a predetermined depth at which a new interface is established free from oxides or fragile intermetallic cpds. The pref. parts are Cu-Zn brass, heated 1 day at 700 degrees C to obtain a surface coating 1-2mm. deep, esp. where one part contains 30% Zn and the other 50% Zn. The process is used industrially to obtain hard surface coatings e.g. of beta brass on an alpha brass substratef or to obtain coatings with anti-corrosion properties or weld ability. It avoids the formation of brittle cpds. on the interface between coating and substrate.
