Title: High speed missile inertial reference optical support and re-initialising system - derives alignment error estimates from comparison of outputs of video camera sensors of reference points located on launcher with values from guidance system
Inventor: HARTMANN ULRICH DIPL ING DR
IPC: G01C21/16
Filed: 1992-07-17
Abstract: Sensors mounted on the missile body detect reference points with known coordinates. The missile body's orientation is derived from the sensor signals and compared with that produced by the inertial reference system. Alignment errors estimated from the results of this comparison are used to re-initialise the inertial reference system. The missile body can be fired from a weapon launcher on which the reference points are arranged. In this case the sensors view in the opposite direction to the flight direction. For an unpowered guided weapon system, the guided weapon forms the reference points and a sensor views in the flight direction and responds to the reference points on the weapon. ADVANTAGE - Ensures highly accurate alignment of inertial reference system nd hence targeting reliability.

Patent DE-4236081-A1 (DE)
Inventor: BEHL ERHARD KONRAD
IPC: B29C33/38
Filed: 1992-10-26
Abstract: The method proposed for manufacturing moulded articles from cellular plastic is designed so that production of the mouldings requires little vacuum and steam and the mouldings have a very low moisture content. This is achieved by using a mould whose cavity walls are made of poorly heat-conducting material or have a suitable low-conducting coating. The mould cavity is evacuated, the expandable granulated material is fed under pressure into the evacuated mould and, when the cavity is filled, steam passed into the evacuated mould. The steam is switched off and the mould cavity again evacuated, the vacuum thus produced being maintained during the stabilization phase. After the stabilization phase, the mould is opened and the moulding ejected using pressure.
