Abstract: An assembly designed to eliminate or attenuate undesirable noises generated by conventional disc brake assemblies when the mounting members for such assemblies become worn with usage. A bias member under compression is disposed in sandwiched relation between a pair of retainer members, one of which is fixedly secured to the fork portion of a motorcycle, and the other of which is fixedly secured to the housing for the braking unit. Thus, the bias member urges such caliper forwardly at all times. Such forward pressure causes the brake caliper mounting pins to seat firmly against the bore formed by the pin guides which are a part of the bracket upon which the caliper is mounted. Although the diameter of such bore will continue to increase attendant operation of the motorcycle, the operation of the compressed bias member will continually accommodate the increased tolerances between the bore and the caliper mounting pins.

Abstract: A reticle brightness control circuit means in a night vision image intenser in which the circuit means utilizes screen current intensity to provide a proportionate amount of current through a reticle light-emitting diode (LED) for controlling the brightness level therefrom as projected on the cathode. When the object image input brightness impinging on the cathode is less than an automatic brightness control limiting level, the screen current limiting level and the reticle LED brightness are directly controlled by the screen current. However, when the object image input brightness goes about the screen current limiting level, the brightness level of the reticle LED is further increased by a decreased feedback voltage from the microchannel plate power supply oscillator (MCP OSC) circuit which provides proportionately more current through the reticle LED wherein the brightness of the reticle image remains commensurate with the input image brightness under all input light levels.

Abstract: A low frequency gain limiting circuit for an AC coupled video processing tem wherein if the low frequency portion of video signals exceed a certain level, the low frequency pedestal is clipped and fed directly to a summing amplifier while simultaneously the low frequency pedestal is differentially compared in a differential amplifier with the original video signals and the resulting short pedestal with the high frequency detail remaining thereon is passed through a high pass filter before application of the high frequency detail only at a second input to the summing amplifier. The addition of the high frequency detail back onto the low frequency pedestal within the summing amplifier provides the gain limited video signal. A video signal comprising low frequency pedestals with amplitudes within the certain level are fed directly through the summing amplifier but no signal will be present at the output of the differential amplifier since both signals cancel.
