  • Patent number: 4473279
    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.

  • Patent number: 4464840
    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.

  • Patent number: 4461422
    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.

  • Patent number: 4458911
    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.

  • Patent number: 4457238
    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.

  • Patent number: 4455033
    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.
