Abstract: ABSTRACT OF THE DISCLOSURE Clock pulses representative of the velocity error between desired and actual train speeds drive an advance train line (ATL) register to count up or down, in accordance with the sign of the error, between zero and a selected maximum count position.  The existing total count is continuously applied to a D/A converter to provide a stepped analog signal which drives an advance train line channel to vary the propulsion effort of the train, car by car, to the next adjacent level, increasing or decreasing per the direction of the counting action.  Attain-ment of either count limit by the ATL register generate, through logic circuitry, a clock pulse to drive the associated propulsion train line (PTL) encoder in the same direction to the opposite count limit during generation of the PTL clock pulse, to continue the stepped variation of the propulsion level in the same direction.  The previously achieved full ATL propulsion level is meanwhile held until the PTL encoder shifts to the equivalent base condition.  All ATL counting action is inhibited by various saturated conditions within the PTL encoder.

Abstract: Modular Motor Abstract of the Disclosure A small motor assembly is shown which requires little, if any, hand work for assembly.  A terminal assembly is associated with the magnetic frame and held in place by the field coils.  The terminations of the field coils are connected to selected terminals of the terminal assembly.  An end bracket which supports an end bearing for the armature and brush holders is secured to the ter-minal assembly to provide a complete motor assembly.  The brush holder is secured to the end bracket by a plurality of protuber-ances which mate with slots in the end bracket.  The brush holder has formed thereon a projection which makes connection with a pre-determined terminal on the terminal assembly when the end bracket is secured to the terminal assembly.  The brush holder may be se-cured to the end bracket in a plurality of positions thereby caus-ing its projection to make a connection with different predetermined terminals on the terminal assembly.  The particular selected po-sition for securing the brush holder to the end bracket and the consequent change of terminal contacted by the projection from the brush holder can influence the direction of rotation of the arma-ture.  The brush and brush spring may be assembled in the brush holder after the end bracket is secured to the terminal assembly.          The brush and spring may be captured in the brush holder by bend-ing an end wall into position after the brush and spring are assembled in the brush holder.  At an appropriate time, wires for connection to a power source may be inserted into appropriate ter-minals of the terminal assembly.

Abstract: Abstract of the Disclosure A method and apparatus for pulling a strand of intestine from a convoluted intestine, such as removed from an animal, and for removing the ruffle fat from the intestine by severing, is disclosed herein.  The leading end of the con-voluted intestine is initially separated from the remaining bulk of convoluted intestine for insertion into the pulling apparatus which includes a work surface inclined downwardly from an entrance end to an exit end.  Between the exit end and the entrance end are a pair of opposed gripping belts, each mounted parallel to the work surface and defining a path be-tween them along which the intestine strand may travel as it is compressively engaged on each side by the belts.  As the belts are driven, the remaining bulk of convoluted intestine is restrained and the belts progressively pull the strand of intestine away from the convoluted bulk.  Ahead of the gripping belts at the entrance end of the apparatus is a circular knife blade which is mounted in a plane parallel to the work surface and at an elevation above the work surface that permits a strand of intestine to be pulled beneath it while the ruffle fat attached to the upper circumferential portion of the strand is held against, and above, the circular cutting knife to sever the ruffle fat from the strand.  The circular knife and one gripping belt are each movable away from (1) an engaging posi-tion adjacent the strand pull path to (2) a clearance position spaced from the path- to enable the leading end of the intestine to be manually placed in the path.  Pivotally mounted above the work surface at the exit end of the apparatus is a baffle plate movable by positioning means into the discharge trajectory of the intestine strand to deflect the intestine strand so as to control the trajectory and disposition of the strand as it passes from the exit end of the apparatus.

Abstract: POWER STEERING GEAR WITH SHORT   PISTON AND FLUID BEARINGS                     ABSTRACT OF THE DISCLOSURE         An integral power steering gear with a valve in the piston is provided having a short piston and cylinder to conserve space and weight.  The input shaft is mounted on a bearing carried by an inwardly projecting annular portion on the bearing cap.  The projecting portion mates with a recess in the end of the piston when the piston is moved to the full extreme in that direction.  The valve guide pin has been relocated at the input shaft end of the valve where maximum support of the valve is realized and improved reversibility of the valve under all conditions is gained. In the bearing cap, both a high pressure seal and a low pressure weather seal are provided.  An insert ring between the two seals serves as backup to the high pressure seal.          In an alternative embodiment, the insert ring may be tapered toward the inside of the gear to allow use of a thin wiper-type seal.  Lubricating grooves in the piston adjacent the output rack provide fluidized bearings to counteract the force of the fluid bearing provided on the top of the piston at the pressurized input slot.  Dual feed passageways extend-ing to opposite ends of the piston have connecting ports drilled from opposite sides of the piston to add further lubrication, but also prevent cross-bleeding between the ports.

Abstract: HIGHWAY CROSSING SYSTEM WITH IMPROVED          RING SUSTAIN FEATURE                  Abstract of the Disclosure A highway crossing warning system includes a motion detector transmitter and receiver respectively coupled to the track rails adjacent the highway crossing for detect-ing motion of an approaching train.  Wrap-around approach sections initiate operation of the highway crossing warn-ing, but once motion is detected, the motion detector can serve to inhibit the highway crossing warning, after a predetermined delay, if motion indication ceases.  To in-crease the effectiveness of the motion detection, the motion detector transmitter impresses a modulated carrier onto the track rails, wherein the modulation is phase locked to the carrier.  The receiver, tuned to the carrier frequency, detects the modulation, and then determines from the level of demodulated signal whether or not approaching motion is detected.  The transmitter employs solid state circuits switched between saturated and off conditions to prevent circuit component failures from masking approach motion.  The ring sustain time period is arranged to provide a minimum constant warning time re-gardless of variations in train movement, so long as train velocity is maintained above a predetermined threshold within a predetermined distance from the crossing.
