Abstract: A railroad frog has either a cast or rail-built point, resting on a baseplate which is fastened to ties. A pair of heel rails are attached to the point, to the ties and to traffic rails. A pair of movable wing rails extend from the toe of the frog to a location adjacent the point of the frog. At the frog point an open wing rail forms a flangeway with the point, while the other, closed wing rail cooperates with the point to form a continuous tread surface through the frog. The wing rails are alternately thrown between the open and closed positions by an actuator. A series of stops define the open wing rail position and act to hold down the open wing rail. The wing rails have hinges which allow them to move. The wing rails have a full rail base at the hinges. Adaptor plates allow use of the frog on concrete ties.

Abstract: A simplified and reliable apparatus for positioning rail cars at a loading or unloading station is disclosed. A rail car movement carriage traverses carriage guide rails anchored to cross-ties between the rail car rails. The carriage includes an onboard hydraulic system in which a single power cylinder activates crossed pivotally connected rail car axle engaging arms in a precision mode. The carriage also mounts a transverse support arm on one end of which is carried a limit switch and limit switch actuator which responds to contact with the flanges of rail car wheels during reverse travel of the carriage to count wheels and thereby establish a proper starting point for the forward movement of the carriage and activation of the car axle engaging arms. The other end of the carriage mounted cross arm is attached to a foldable feed tray which receives and stabilizes an electrical cable supplying power to a motor and valve of the hydraulic system on the carriage.

Abstract: An apparatus including a source for producing a concentrated light beam, such as a laser, a background spaced from the source against which the light beam is directed, and a transport arrangement for moving translucent bodies, such as French cut potatoes, through the light beam. Another light source illuminates the background independently of the concentrated light beam. A receiver receives light reflected from the background and from translucent bodies moving through the light beam, as well as from the independent light source illuminating the background. The receiver produces an output signal which changes when an impurity enters the concentrated light beam, and this changed signal is used to operate a device which removes the impurity from the remainder of the translucent bodies. The light beam may be scanned across a plurality of rows of moving bodies by directing the beam at a rapidly rotating multifaceted mirror.

Abstract: An arrangement for fastening rails to sleepers includes guide plates (10) disposed to the sides of each rail and elastic clips (20), which may be pressed onto the respective guide plate (10) and onto the foot of the rail by means of bolts (30) anchored in the sleepers, the guide plates (10) having on their upper side in the installed position a rib (13) extending parallel to the rail, on which a part (21) of the elastic clip may be brought to seat as a boundary for the stress path.In order that the guide plates (10), when made also from plastics, may safely carry without damage the forces exercised by the clips (20), even when there has been an excessive torque on the bolts (30), each rib (13) of the guide plate (10) has a reinforcement (14) in the seating region of the clip (20).

Abstract: A railway car underframe includes a center sill having a central section and opposite end sections. The sill includes spaced vertical walls, and upper and lower walls which are slotted in registry the length of the central section, and which form in cross section a spaced I-beam construction. The construction provides a sill having high torsional flexibility which is necessary to accommodate the railway car to track conditions tending to derail the car when single axle suspensions with two wheels are utilized. The sill also includes a separator in the form of a channel which includes flanges at its sides which are secured to the vertical walls of the sill. The separator extends substantially the length of the slots and is effective to resist lateral forces tending to buckle or permanently deform the sill during operation, while not adversely affecting the high torsional flexibility which is required in the sill structure.

Abstract: Motion is imparted to a car (12) by a cable (10) that runs along the length of a guideway (14) in sheaves (22). To accommodate directional changes in the guideway (14), the sheaves (22) are oriented in a range of configurations, including orientations (22C, 22D) above the cable (10). A guiderail (30) is located high on a side of the guideway (14) and imparts guidance to the car (12) via a rail follower (38) on the car. A cable clamp (54) attaches the car (12) to the cable (10) and displaces the cable (10) a large amount from the sheaves (22) to avoid impingement of the clamp (54) and sheaves (22). The cable clamp (54) is disposed so as to occupy the area defined by the rail follower (38). Cable supports (56,56), disposed forward and rearward of the cable clamp (54) displace the cable (10) by a small amount from the sheaves (22) and replace the cable (10) onto the sheaves (22). The cable supports (56,56) are disposed so as to occupy the area defined by the cable as displaced (55) by the cable clamp (54).
