    摘要: A diesel-electric locomotive transition programmer includes a digital axle speed transducer and digital solid state logic isolated from transients in the environment of a moving locomotive. A signal representing the speed of a traction motor, sensed by the transducer, is filtered. Digital components of the filtered signal are counted over a fixed time interval. The value of the count is decoded to selectively actuate relays which isolate the solid state circuitry from transients. Relay outputs drive locomotive transition relays to appropriately energize the shunt windings of locomotive traction motors.

    摘要: A control system is disclosed permitting the control of a plurality of power traction units in railroad service from a single one of such units as the master control unit. Both indicator and command signaling are provided between the various units by means of inductive couplers mounted in the vicinity of the mechanical unit couplers. Frequency shift keying and redundant signal encoding are employed to provide a high degree of reliability with protection against failure and errors.

    摘要: A compact, air-damped accelerometer useful for aerospace applications is disclosed having a seismic mass limited to rectilinear motion along a predetermined sensing axis by symmetrical cantilever spring suspensions coupled to each end of the mass. Each cantilever suspension includes a pair of springs each having connected inner and outer ring portions. During imposition of accelerations transverse to the sensing axis, the inner portion of one spring and the outer portion of the other spring are subjected to compressive loads that are equal and opposite and therefore cancel so that no deflection error is introduced. The remaining ring portions of the springs are subjected to equal and opposite tensile loads the effects of which therefore also cancel.

    摘要: A rate table apparatus is disclosed in which the turntable is supported by a substantially frictionless, self-centering hydrostatic liquid bearing including concentric shaft and spindle members defining thrust bearing means for reacting to axial loads and radial bearing means for reacting to journal loads, the bearing means being contiguous and in compact spatial relation. Both bearing means share common liquid supply and return conduit systems.
