Abstract: A rail seat which includes a) a rail tie b) a pair of rail fastening support shoulders mounted on said rail tie so that a rail can be held to the tie between said shoulders each shoulder having a a rail face and side portions on each side of said rail face extending away from the rail c) a rail pad adapted to lie on said tie between said shoulders which has a pair of projections extending parallel to the tie along side each side portion of each shoulder. The rail seat is adapted to be used with a deep post insulator and incorporates a rib on the support shoulder extending from each side portion against which a face of the rail pad projections abut to locate the pad in position to accommodate the post of the insulator. The rail pad projections are proportioned to prevent the pad from moving out of position under the creep load conditions present when rail cars pass over the rail seat.

Abstract: There is provided a method for non-scanning multi-pixel ranging of a scene, comprising the steps of providing a single detector/receiver associated with a time-delay arrangement, producing a time-arrival distribution of pulse echoes of at least part of a remote scene in a defined ranging plane, receiving said distribution as produced on the ranging plane and conveying it, echo pulse by echo pulse through a plurality of echo pulse conveying means to the single detector/receiver, while introducing a time delay, whereby the echo pulses arrive at the single detector/receiver in a sequential order, and using an electronic logic to reconstruct the time-arrival distribution from the time-delayed echo pulses received by the detector/receiver. Systems for ranging of a scene are also provided.

Abstract: According to the present invention, a hinge device which may be mounted with one action without fixing and mounting the hinge device with any other discrete part and is superior in mounting work, in which a cam portion 4 is provided within a mounting case body 3 in a rotation preventing manner, the cam portion 4 is provided slidably movably within the mounting case body 4 against an engagement biasing spring 5 provided within the mounting case body 3, a cam engagement portion 6 for engaging with the cam portion 4 by the engagement biasing spring 5 is provided in confrontation with the cam portion 4, the cam engagement portion 4 or a mounting portion provided in the cam engagement portion 6 is provided projectingly on one side of the mounting case body 3, the mounting case body 3 is provided in a fixed condition to the first member 1, the cam engagement portion 6 or the mounting portion provided in the cam engagement portion 6 is provided in a fixed condition to the second member 2, when the second member 2 is

Abstract: Helical wind rotor, comprising at least two blades (1) which, as observed in cross section, are of substantially equivalent shape and curved, and are located parallel with the rotational axis (o) and so that the blades (1) are arranged most suitably at equal intervals with respect to the rotation angle of a cylindrical co-ordinate system (o, z). In order to bring about helical form of the wind rotor, the blade cross sections (sp) are arranged to revolve in the longitudinal direction (z) of the wind rotor. The blade cross section (sp) belonging to the wind rotor is arranged substantially different from the shape of semicircle, so as to enable manufacturing of the blade of a substantially planar blank. The invention also relates to a method for manufacturing a wind rotor of the above presented type.
