Abstract: There is disclosed a trolley which runs along unfastened rails of a track, in which each rail is positioned between a respective one of two pairs of housings on each sleeper, the trolley moving from sleeper to sleeper in order to complete permanent fastening of the rails to the sleepers. The trolley has a pair of rail-clip driving apparatus on each side, one associated with each rail, of which each comprise a pair of magazines for storing e-shaped clips, and a clip driver for each magazine which drives a lowermost clip in a stack of clips in the magazine into a sleeper housing. Each apparatus includes a longitudinally displaceable support tube on which the magazines are mounted, the tube moving one way or the other depending upon which magazine first comes into cooperation with its respective housing in order to bring the other magazine into cooperation with its housing.

Abstract: A device for cleaning transparent plates mounted in the detecting sections of a color sorting apparatus adapted to sort granular materials such as rice according to their colors. The device has a guide rail extended in parallel with each transparent plate, a cleaning plate assembly having a wiper making a close contact with the surface of the transparent plate and movably mounted on the guide rail, and means for reciprocatingly driving the cleaning plate assembly along the guide rail. The driving means may incorporate a reversible motor fixed to the cleaning plate assembly and a roller drivingly connected to the shaft of the motor and adapted to roll on the guide rail. As the driving means operates, the wiper of the cleaning plate assembly wipes off the contaminants on the surface of the transparent plate to clean the latter, thereby to ensure stable sorting operation of the apparatus.

The clip retainer includes a clip receiving bore in which one end of the clip is received. The clip retainer may be adjusted relative to the shoulder to adjust vertically the position of the clip receiving bore relative to the bed. Intermeshing teeth are provided between the shoulder and the clip retainer to lock the retainer to the shoulder in the required position.

Abstract: An anchoring device for use in anchoring a railway rail-fastening clip to a foundation for a railway rail has a head part, which anchors the clip and is to lie above the foundation, and a tail part which is to lie in the foundation and is in the form of a single vertical rod. At least one vane, to resist turning of the device about its vertical axis, has its upper extremity joined to the bottom of the head part and has one of its sides joined to the upper portion of the tail part, the vane having a vertical length and a horizontal width greater than its horizontal thickness. At least one projection, below the vane or vanes, projects laterally from the tail part and has a horizontal or nearly horizontal top, the projection or projections serving to resist vertical forces tending to pull the anchoring device vertically upwardly out of the foundation.

Abstract: A color sorting apparatus has a chute from which grains come out in the form of a linear flux, a photoelectric detection device surrounding the flux and including light sources, light-receiving units each having a lens barrel having a filter unit and adapted to receive the light reflected by or transmitted through the flux of grains, and a jet nozzle which provides a jet of air in accordance with the signal from the light receiving units thereby to blow unwanted grains of different colors away from the flux, so that the desired grains and unwanted grains are separated from each other according to their colors. The filter unit consists of a plurality of filters carried by a plate member which is movably mounted on the lens barrel.

Abstract: Apparatus for measuring the thickness of a workpiece (34) at a plurality of predetermined points separated one from another along a predetermined measurement line. A caliper has first and second opposed jaws (20, 22) mounted on a support (19), which is biased to maintain the first jaw (20) in contact with a first surface of the workpiece. The second jaw is biased relative to the support to maintain the second jaw in contact with a second, opposite, surface of the workpiece. A transducer (24a) is controlled by the second jaw to produce an output signal representative of workpiece thickness. The workpiece is mounted for relative movement between the workpiece and the caliper so that the predetermined measurement line passes between the jaws of the caliper. The output signal is sampled as the predetermined points pass between the jaws of the caliper, and the sample signals are processed to provide thickness measurements at the predetermined points.

Abstract: A railway spike consists of a bar folded to form first and second legs. Proceeding upwardly from the nose, formed by the two ends of the bar, firstly there is a first portion in which the legs are straight and parallel, then a second portion in which they diverge, then a third portion in which they converge, then a fourth portion in which they diverge again and finally a fifth portion which includes the uppermost part of the spike. When the first leg is on the left, no part of the fourth or fifth portion of the spike is further to the left than is the leftmost part of the first leg in the second and third portions. The spike may pass through a hole in a baseplate on which a rail stands, a resilient clip having a portion which bears downwardly on a flange at the bottom of the rail and having a further portion which presses upwardly on a flat surface at the bottom of the plate.

Abstract: A centering mechanism for maintaining a tunnel structure equidistant from the two parts of an articulated vehicle. The mechanism includes a base plate pivoted to the tunnel structure and having a pair of vertical pins spaced apart on the base plate. Each of the pins accommodates a pair of levers which have toothed portions meshing with tooth portions on aligned levers on the other pin. The levers are connected in pairs to the adjacent chassis member by links so that upon movement of the chassis members about a horizontal axis, equal and opposite rotation of the links occurs to keep the tunnel centered.

Abstract: A railway truck assembly adapted to produce steering of the wheel axles radially to a curve to reduce wear and noise and characterized by a pivot connection between the bolster and the truck frame elements which; in cooperation with direct transmission of the load to the truck frame through the opposite ends of the bolster, allows to use a relatively thinner and centrally non-bulging bolster. Thus, more space is made available between the central portion of the bolster and the top of the rails; which space is advantageously used to install some equipment such as for instance a linear induction motor or LIM.

Abstract: A method of controlling a digital actuator which controls the fuel injection pump for the internal combustion engine. In the control method for minimizing the difference between the reference command value and the resultant controlled value in response to the reference command value, the command signal is issued in such a way that the time interval from a command signal which has been issued based on the difference and the subsequent command signal is longer than a predetermined period.

Abstract: An articulated vehicle includes a pivotal connection to permit movement between the chassis portions about a vertical and a horizontal axis. To reduce lateral deflection between the chassis portions a torque transmitting linkage is mounted at roof level and comprises a pivoted link mounted on a vertical pin on one of the chassis members. A pair of lateral links extend from the pivoted link to the other of the chassis members. The lateral links are generally parallel and prevent pivotal movement of the pivoted link upon a lateral force being applied to one of the chassis members.
