    摘要: A method and apparatus for a production tubing safety valve having a rotatable ball closure means for shutting in a well at a subsurface location which is operable in response to fluid pressure in an annular area between the production tubing and the well casing. The valve mounts means for sealing the annular area adjacent the valve wherein the differential pressure urging established across said seal communicated to the valve effects operation thereof and means for mounting the valve with the well casing for supporting the valve in the well. The safety valve may be releasably locked in the open position when a directional pressure is communicated thereto through the production tubing.

    摘要: Cored and peeled pineapples, split or halved axially into half spheroids, are fed through segmenting, slicing and usually also recoring operations in the form of a column of end-to-end half spheroids lying flat face down on supporting means having a longitudinal guiding rib slidably engaged by the aligned longitudinal grooves formed by the initial coring operation. Positive feeding of the half spheroids to and through the slicing and recoring operations is provided by a scroll feeder near the head of the column having lateral engagement with the leading half spheroids which have been segmented except for a small amount of unsegmented material immediately adjacent to the core hole, prior to reaching the scroll. The advancing head of the column leaving the scroll is sliced transversely at intervals which provide partially segmented slices of the desired thickness. The advancing head of the column is then recored producing the desired chunks by severing the segments from the ring of material adjacent to the core hole which held the pieces together through the slicing operation.

    摘要: A drilling tool connected in a drilling string includes a pressure responsive rotatable ball valve for enabling drilling fluid flow down the bore of a drill string which automatically rotates closed for blocking flow through the bore of the drill string when incipient pressure conditions indicate the direction of flow through the bore may be reversed. Means for releasably locking the ball in the open position in response to a preselected directional pressure to enable the running of other tools and the like through the bore of the drilling string are provided. The drilling tool may be employed for controlling an undesired flowing stream of fluid from the bore of the drilling string by stabbing the tool to connect with the drilling string utilizing a stabbing member which is removed after connecting to enable the ball valve to rotate closed to control the flowing stream.
