| 41 | Railcar brake structure | US09122577 | 1998-07-24 | US06216604B1 | 2001-04-17 | James W. Forbes; Richard C. Haight |
| An articulated railcar has several well car units for carrying shipping containers, highways trailers, or a combination of the two. The well car units permit the nose of a highway trailer to overhang the articulated connection between two adjacent cars. A brake valve is located in a relief formed in the main bolster of one of the articulated units, out of the way of the overhanging trailer. Each well car unit has a side beam having a roll formed top chord reinforced by a top chord plate, a downwardly extending web, and a lower sill formed of a thick angle. The service, or auxiliary, and emergency brake reservoirs are mounted in a saddle bag configuration to the outside face of the webs of the opposite side beams of the articulated unit, tucked underneath the reinforced roll formed top chord. | ||||||

| This disclosure relates to a control system for suppressing wheel squealing noises produced by an activated frictional type of fluid pressure operated railroad car retarder. A microphonic transducer is disposed in the immediate vicinity of the car retarder for picking up and converting the sound wave pressures into alternating current signals. A band-pass filter network is arranged to pass a select band of frequencies of the alternating current signals. A diode rectifier converts the passed alternating current signals into a d.c. voltage. An integrating circuit produces an output signal which is substantially the time integral of the d.c. input voltage. An operational amplifier compares the output signal of the integrating circuit with an input reference signal and produces an output signal when the output signal is greater than the input reference signal. The output signal drives a power amplifier for causing the energization of an electromagnetic exhaust valve which deactivates the car retarder.
