In addition, a mammalian iris may be dilated by inserting the at least partially dehydrated iris dilator described above into a position radially inwardly from the iris where, in the presence of bodily or surgical fluids, the dilator hydrates and expands to engage and dilate the iris. An apparatus for deforming the dilator to facilitate insertion in use includes top and bottom surfaces which engage top and bottom sides of the dilator, respectively, at least one depression member for forming a depressed area on an edge of the dilator and at least one retainer member for retaining a non-depressed area on the edge of the dilator.

  • Patent number: 5427723
    Abstract: A distinctive method for contouring a fibrous web includes the steps of (a) providing a fibrous web which defines an interconnected series of appointed article segments along a length dimension of said web, and (b) conveying said web at a selected speed along an appointed machine direction. The method also includes the step of (c) removing predetermined quantities of fibers from selected regions of said fibrous web with a moving, outer peripheral scarfing surface, which is movable along a selected movement direction. The scarfing surface is constructed to provide each of the article segments with a selected contoured basis weight which varies along the length dimension of said segment in a selected correspondence with a predetermined scarfing pattern. The scarfing pattern is provided by the outer peripheral scarfing surface and is variably patterned along the movement direction of the scarfing surface.

  • Patent number: 5403532
    Abstract: A process for the production of a gasket is described, in which at least on one side and at least on all bearing points in the use case a three-dimensional sealing surface complimentary to the deflection of the surfaces to be sealed is permanently shaped prior to assembly, as well as a tool for performing the process. An assembly pattern is produced in such a way that a plastically deformable material is fixed between the surfaces to be sealed. A negative copy or form of the assembly pattern is produced on the circumferential surface and the gasket is produced accompanied by the rolling of the stamping roller.

  • Patent number: 5314324
    Abstract: The present invention generally relates to a device which can form a lid for a cup. This apparatus is for thermoforming a plastic sheet of material into a plurality of production sheets. Each sheet has a partible port section, which has integrity against passage of fluid, yet which is partible under mechanical pressure so as to open and allow the passage of fluids. The lid structure with a breakaway port is formed by an apparatus including an oven for heating the production piece, mold assembly that has a mold formed as a female cavity with a plurality of grooves formed around the cavity surface and a pressure box assembly that has an open position and a closed position. The breakaway port in the lid structure is formed as a female cavity with accordion-like grooves therearound which expand to engage the outside of the straw. This eliminates escape of the fluid through the breakaway port when the straw is inserted.

    Abstract: A method of manufacturing molding members, for instance for automobiles, wherein an elongate shaped body is prepared from synthetic resin material either by an extrusion process, or by an injection process and is subjected to a controlled heating so as to soften the interior resin material while preserving the hardness of the outer surface portion. A cutter blade is advanced into the shaped body while it is subjected to the controlled heating, whereby the outer surface portion is urged and deformed inwardly to form a smooth end surface in continuous connection with remaining outer surface of the molding member.

  • Patent number: 4698227
    Abstract: In the production of ceramic plates, the wet uncured extruded clay substrate is cut into plate shaped pieces by vertically reciprocating punching knives disposed about at least a portion of a plate shaped area. A pressure plate is mounted within the punching knives and vertically movable against spring forces therewithin so as to maintain downward pressure against the substrate material during the plate cutting operation. Chamfered plate edges are formed by special chamfering knives adjustably mounted at the edge of the pressure plate. The chamfering knives depend from the pressure plate and extend outwardly into contact with and inside wall surface of the punching knives so as to avoid undesirable burrs at the plate edge and also to permit convenient adjustment of the chamfering knives to compensate for wear.

  • Patent number: 4469476
    Abstract: Wafers are produced by guiding a sheet of bread having friable outer crusts and a relatively soft center through wafer forming apparatus. The apparatus includes a pair of rolls, one of said rolls, i.e., a cutting roll having one or more wafer forming recesses or cavities therein and the other roll being a pressure roll which operates in rolling engagement with the cutting roll. As the sheet of bread is introduced into the nip formed between the two rolls the pressure roll acts to press the bread into the cavity or cavities on the cutting roll and into engagement with the edges of the cavity or cavities to cut wafers from the sheet of bread. Each cavity is configured to have a bottom surface which rises as a gradually tapering wall to a cutting edge which is coterminious with the surface of the cutting roll.
