    Abstract: A member oscillates on a face and another member pivots on a bed of the first member. Passages are provided through the members to lead a lubrication fluid under pressure into a fluid pocket between the mentioned face and one of the members. The fluid pressure in the pocket carries a major portion of the load of one of the members on the face. The oscillation of the members has one stroke under higher load and one under less load. The pivotal movement of the other member controls the flow of fluid through the passages to provide high pressure in the fluid pocket at the stroke under higher load and lower pressure in the pocket at the stroke under less load. The arrangement is especially suitable to be provided on pistons and piston shoes of radial piston machines. But it can also serve to carry load on other members of machines or vehicles, wherein at least two movements are taking place and a source of supply of fluid under pressure is available.

  • Patent number: 4926756
    Abstract: This invention applies the linkage connected between the interaxle yokes of a truck and a railroad vehicle car body so as to create radially steered alignment of wheelsets on circular curves without reference to the truck frame. Forces exchanged between the wheelsets and the car body are essentially longitudinal and no significant lateral forces are created on the truck frame or car body from the steering action. The steering linkage utilizes the longitudinal component of relative motion of a point on the car body with reference to the vehicle truck to cause relative pivotal movement of the interaxle yokes thereby guiding the wheelsets to a radial alignment. Radial alignment is achieved by suitable proportioning of the links of the mechanism.

  • Patent number: 4926775
    Abstract: A cleaning apparatus for use under water, particularly for cleaning vertical surfaces which are fouled by marine organisms. One or more nozzles (19a-c) for spraying water at high pressure at a surface to be cleaned are arranged on a rotary disc-shaped unit (14)where the rotation axis is intended to be generally perpendicular to the surface which is to be cleaned. The nozzles are obliquely located in a circular plane so that the rotating unit (14) can rotate. Beyond the periphery of the rotating unit (14) there is a casing (12) which forms an annular chamber (13) with an outlet which is at least partly directed away from the surface which is to be cleaned. The annular chamber (13) is formed from two generally cylindrical or truncated conical casing units (20, 30) which are positioned at a radial distance from each other with their internal ends concentric with respect to the nozzle holder (11).

  • Patent number: 4926779
    Abstract: The marine anchor has two symmetrical flukes, each one of them fitted with a pair of symmetrical ledges. Between the flukes, a shank is capable of pivoting around a transverse shaft that joins the two flukes, so as to form, relative to the shaft, a fore arm and a rear arm. The free end of the rear arm carries transverse stop-pins. An oblong aperture is provided in the shank, for the passage of a shaft that joins the flukes. The stop-pins come into abutment against the ledges of the flukes when the shaft is in the rear part of the aperture. The stop-pins are released from the ledges when the shaft is in the fore part of the aperture. The aperture has the general shape of a truncated triangle, the axis of symmetry of which is one and the same with the longitudinal axis of the shank, the long base of the truncated triangle being in the fore. Under normal conditions, elastic or breakable lug pieces limit the movements of the stop-pins when they are released from the ledges.
