  • Publication number: 20180181209
    Abstract: A proximity sensor including a housing, light emitters mounted in the housing for projecting light out of the housing along a detection plane, light detectors mounted in the housing for detecting amounts of light entering the housing along the detection plane, whereby for each emitter-detector pair (E, D), when an object is located at a target position p(E, D) in the detection plane, corresponding to the pair (E, D), then the light emitted by emitter E is scattered by the object and is expected to be maximally detected by detector D, and a processor to synchronously activate emitter-detector pairs, to read the detected amounts of light from the detectors, and to calculate a location of the object in the detection plane from the detected amounts of light, in accordance with a detection-location relationship that relates detections from emitter-detector pairs to object locations between neighboring target positions in the detection plane.

  • Patent number: 8840159
    Abstract: A container yoke for lifting of at least one container, including a base frame, two travelling beams, which are telescopically displaceable in the base frame and on whose outer end portions are arranged transverse beams provided with locking members, so called twist locks, for engagement in, and locking to, the corner boxes of a container. The container yoke includes cables arranged to displace a respective travelling beam into the desired position in the frame of the container yoke. The cables, for displacement of a travelling beam, are simultaneously reeled up and unreeled with the aid of one and the same cable drum. Two cable drums of the container yoke are driven by a common actuator, and the cables are fastened in the end portion of a respective travelling beam via spring-loaded cable tensioners.

  • Patent number: 6425322
    Abstract: The present invention is for a log made from wastes from forestry and the like material. The invention also is for means and method for the production of such log. The log comprises a sheath which surrounds the compressed forestry wastes of the log. A log according to the invention is produced by that forestry wastes is compressed. The goods are fed to a delimited space which corresponds to the outer shape of the log. In this space the goods are rotated around the lengthwise axis of the log to be during compression after which a holding, moisture releasing sheath is applied during rotation. In the compriming engine the log is formed inside the space which is defined by the compression rolls and the side walls including their movable side wall parts.

  • Patent number: 4795203
    Abstract: A container and trailer-handling combination yoke having lifting arms mounted at the opposite ends of two transversely extending, longitudinally spaced yokes interconnected by a telescopically extensible frame, are mounted for pivoting between respective generally vertical, operating positions and generally horizontal elevated positions. The arms are mounted to the respective yoke ends via respective intermediate members which are themselves pivotally mounted to the yokes about respective generally horizontal, longitudinally extending axes, so that the elevated arms may be swung inboard to storage positions lying transversely inboard of the respective ends of the yokes. Preferably, hydraulic double cylinders are used for swinging-up the lifting arms.

  • Patent number: 4315124
    Abstract: An inductive billet heating apparatus in an inductive heating furnace for billets of rectangular section uses a plurality of paired heater modules having a flat shape. The billets are fed by a plurality of paired roller elements and each heater module in each pair of heater modules is suspended from respective ones of the paired roller elements on opposite sides of the billet such that a substantially constant distance from the opposite surfaces of the billets to the respective heater modules is independent of the thickness and/or straightness of the billets. At least some of the heater modules may be mounted to be rotatable in a plane parallel to the respective surfaces of the billets. The heater modules may be series-connected in pairs and the paired heater modules either series-connected or parallel-connected in groups.
