Patent EP-0259079-A2 (EP)
Inventor: HUGHES JOHN THOMAS
IPC: F16L59/05
Filed: 1987-08-24
Abstract: A method of moulding shaped articles of microporous thermal insulation material comprises providing a mould which is dimensioned so as to be smaller by a predetermined amount than the corresponding dimensions of the desired shaped article and charging a predetermined amount of an intimate mixture of a microporous thermal insulation material (15) into the mould. The intimate mixture is compacted within the mould by means of a die (16) which is urged towards the base of the mould within an area defined by side walls (13) of the mould. Subsequently at least a part of the side walls of the mould are removed while the compacted intimate mixture remains under compression due to the urging of the die towards the base of the mould and then the die is released so as to allow the compacted intimate mixture to expand freely.

Abstract: A system for retracting a pilot into an ejection seat during either normal flight or an emergency ejection procedure. A pair of haulback straps (14, 16) are wound on a haulback reel (12) that is rotatably driven by a gas-powered motor (24). The motor receives pressurized gas from the aircraft's bleed air during normal flight and from a pyrotechnic cool gas generator during an ejection. The rate of gas flow to the motor is controlled by a servovalve (50). The actual rotational velocity of the haulback reel is measured by a tachometer (40) and compared to a desired haulback velocity profile. A control signal that is proportional to the difference between the actual haulback velocity and the desired haulback velocity is applied to the servovalve (50) so that the desired haulback velocity is achieved. The desired haulback velocity may vary as a function of time from the start of an ejection procedure. The system also includes an acceleration sensor (64) for actuating a haulback reel locking mechanism when excessive g-loads are sensed, a reel lock (28) actuated if the haulback straps (14, 16) unwind from the haulback reel at an excessive rate, and a spring-loaded winding mechanism (42) to apply a relatively small winding torque to the haulback reel (12) to prevent any slack from developing in the haulback straps (14, 16).
