Abstract: Method and apparatus for driving the motion system of a flight trainer to simulate aircraft buffeting which method and apparatus avoids the resonant frequency of the motion systems hydraulic actuators by using a "Linear Tracking Band-Stop Filter". Band-stop filter circuitry is combined with linear tracking band pass filter circuitry to provide the linear tracking band-stop filter. This circuit receives command signals intended for the servoamplifier used to drive a hydraulic actuator. The band-stop filter eliminates or substantially attenuates those frequencies contained in the command signal which would cause resonance of the hydraulic actuator. It has been discovered that the resonance frequency of the hydraulic actuator varies as a function of the extension of the actuator, and therefore in this invention the center frequency of the band-stop filter tracks the resonant frequency of the actuator such that a much smaller band of frequencies is eliminated.

Abstract: For powder filling of cables, in a fluidized powder bed, it has been proposed to pass the cable core through the bed in a substantially closed condition. There is a limit to the number of conductors a core can have for effective filling.

The opening member is freely ridable on the cable core and has a hole for each unit. The opener is held against a support member and an air bearing formed between the two members. Air is also usually fed to the holes in the opener member through which the core units pass to prevent flow of powder out from the bed. The opening member can be positioned in the fluidized bed or outside immediately prior to passage of the cable core through the bed. The units are each in a substantially closed condition in the bed and the units close to a single core also in the bed.
