  • Patent number: 5654024
    Abstract: Apparatus and methods are disclosed for removing palm hearts from the tapered and "meristem" sections of cut lengths of stalks of palm, each of which had included a large "meristem" section joined to a smaller diameter top section by an intermediate tapered section, and had a palm heart that runs the length of the stalk as a core member inside an intermediate layer that is surrounded by a thorny outer bark layer. After removel of the smaller diameter section from the remainder of the stalk, the remaining tapered and "meristem" sections are caused to be retentively positioned in coring means by which, backed by means for retaining the work piece in position, a coring knife moves substantially coaxially to the piece from one of its ends to core out and remove the palmheart core from the remainder of the work piece. Embodiments include such means per se and methods for carrying out the foregoing processes.

  • Patent number: 5454300
    Abstract: Apparatus and methods are disclosed for removing palm hearts from cut lengths of stalks of palm each of which includes a large "meristem" section that is joined to a smaller diameter top section by an intermediate tapered section, and has a palm heart that runs the length of the stalk as a core member inside an intermediate layer that is surrounded by a thorny outer bark layer. Each such stalk is caused to move longitudinally through bark removal means for slitting the outer bark layer of its smaller diameter section and removing the bark from the remainder of the stalk. The smaller section, after having been severed from the rest of the stalk, is caused to move longitudinally through intermediate layer removal means for slitting and removing the intermediate layer from the underlying palm heart. Embodiments include each such means per se and acting cooperatively with the other, and methods for carrying out the foregoing processes.

  • Patent number: 4260483
    Abstract: In accordance with the present invention, methods and machinery are provided for automatically inspecting shaped, lined closures and rejecting those which fail to meet pre-established criteria for shape and seal. Specifically, shaped closures having concave interior portions and resilient sealing liners are supplied to an inspection station comprising one or more female inspection nests for receiving individual closures and one or more respective male inspection heads for insertion into the concave portions of respective closures. The inspection heads are provided with exterior shapes approximating the interiors of ideal closures so that penetration into the closure indicates the conformity of the closure to the ideal. Preferably, the inspection head is connected to a source of pressurized fluid for testing both the depth of penetration and the adequacy of the sealing ring.
