  • Patent number: 4213359
    Abstract: The shaped block in the path of the fluid from the nozzle of a high pressure fluid jet to be located below the material to be cut or slit by a jet including, preferably, a curvo-linear passage or bore through the block having an entry port aligned with the nozzle for receiving and directing the flow of fluid from the jet after it has slit the material and preventing the fluid from returning to or splashing upon the material after it has entered the passage and a replaceable slug for insertion into the block in the area where the high pressure fluid impinges as it enters the passage.

  • Patent number: 4181240
    Abstract: A flexible dispenser for dispensing the top sheet of flexible material from a sheaf or pile of flexible materials such as paper, comprising an anchor for anchoring the dispenser, for example, in the form of a flange to be interposed between the top edge of a sheaf of paper and the front wall of a receptacle containing such paper, and a flexible or partially flexible relatively elongate dispensing member as such dispenser extending over the top sheet of paper and provided near its bottom edge with friction gripping substance on the top and bottom surfaces whereby when the dispensing member is moved rearwardly away from the point of ultimate emission of the paper, it will bow into a convex configuration causing the top sheet of paper to assume a similar configuration causing it to lift away from the remainder of the material in the sheaf and become available to be grasped for removal from the receptacle.
