Abstract: The invention provides contact lens packages in which removal of the lens is facilitated by providing a means for elevating the lens when the package is opened.

Abstract: The present invention relates to a one-step fastening device, a process for creating a fastener utilizing such a device, and the end fastener produced thereby. In this regard, the invention uses an outer, hollow fastener material that can be partially compressed under tension at designated areas (i.e., a compression member) and an inner activation or tensioning member. The compression of the outer fastener material occurs at one or more flexible areas or compression features specifically located on the longitudinal axis of the material. As a result, the outer compression member is capable of being distorted or bent under tension to produce a predetermined configuration. The device described herein has the ability to form specific and controllable fasteners of designated shapes and configurations. Methods for fastening, snaring, gripping, cutting, and manipulating material using the device in a confined space are also provided.

Abstract: A contact lens package has a body with a lens receptacle therein covered by a hinged lid. The lid is offset on the body such that a ledge is formed by the base and an overhang by the lid. The ledge has a plurality of upstanding lugs that insert into mating receptacles formed in the overhang of an adjacent contact lens package, permitting the ganging of packages together for functional and aesthetic reasons.

Abstract: An ophthalmic lens package comprises a shell having an internal cavity accessible through an opening in the shell and a drainage member that divides the internal chamber into an upper chamber and a lower chamber. The drainage member is permeable to aqueous liquids and is arranged to allow drainage of liquid from the upper chamber to the lower chamber. This arrangement of the ophthalmic lens package allows the consumer to retrieve the lens from the upper chamber without handling any significant amount of saline solution.

Abstract: A medical pump, for use with a cassette having a pumping chamber, includes a pumping element with a piston slider assembly which intermittently pressurizes the pumping chamber during a pumping cycle and has a piston head connected to a main body with a single pressure sensor positioned therebetween. A camshaft is associated with the pumping element, an inlet control element, and an outlet control element for closing the pumping chamber to flow when the pumping chamber is pressurized. A processing unit receives pressure and position data from the pressure sensor and a position sensor associated with the pumping element, and processes this data to determine the operating condition of the pump. The operating conditions determined include: blocked fluid flow, no fluid in the line, no cassette associated with the pump, proper pump priming, or proper valve sealing.

Abstract: A string trimmer head and head assembly include a plurality of arms which connect the head to a hub member. One or more flails are captured between the head and the hub member and extend outwardly into a cutting plane.

Abstract: A method and apparatus for applying granules to a coated asphalt sheet to form at high production speeds with shingles a variegated pattern having uniform pattern edges. Granules of a first color are applied to spaced first areas on a continuously moving tacky asphaltic strip, such as a hot asphalt coated organic or glass fiber mat. Hot asphalt or another adhesive is applied to at least a portion of one or both of the leading and trailing edges of the first areas to provide predetermined uniform edges to tacky second areas between the spaced first areas. Granules of a second color are then deposited on the second areas. The granule coated strip is then cut into shingles. The method may be used to create multiple pattern areas with two or more different colored granules or granule blends.

Abstract: Plastic-film zipper bags having tubular plastic end stops bonded to the plastic zipper to seal the ends of the zipper and to provide stops to retain a slider on the zipper are disclosed. Also disclosed is a method of installing the tubular plastic end stops on the zipper.

Abstract: A plastic reclosable fastener with slider particularly suited for plastic bags and the like wherein the reclosable fastener is provided with structure located below the interlocking elements of the fastener which when engaged by the slider controls the opening and closing of the interlocking elements of the fastener.

Abstract: A method of assembling a multi-part plastic slider as a unit with a plastic reclosable fastener on plastic-film bags is disclosed. The multi-part plastic slider includes a support member with a separator finger depending therefrom and two sidewalls joined to the support members by sliding joints on the opposite edges of the support member so that the support member and sidewalls may be partially assembled into a unit which unit is then assembled with the zipper by sliding movement of the sidewalls axially on the sliding joints on the opposite edges of the support member to bring the slider into fully assembled condition.

Abstract: A container for transporting laboratory-type animals comprises a base and a lid, wherein the base and the lid when assembled define a volume for receiving one or more laboratory animals therewithin. The base includes a flange for contacting the lid, wherein the lid is removably attached to the flange of the base with removable stitching.

Abstract: A plastic reclosable fastener with slider for opening and closing the reclosable fastener on plastic-film bags and the like is disclosed. The plastic reclosable fastener and slider include a provision for restraining the slider in closed position and thereby maintaining the male and female elements of the fastener in interlocking relation to avoid inadvertent opening of the elements of the fastener when the slider reaches the fully closed position at the end of its travel along the fastener. The ends of the flanges of the fastener that are created by the slider-restraining notch are provided with diverging structure to facilitate re-entry of the slider separator structure between the flanges when the slider is moved toward the opposite end of the fastener to open the male and female elements of the fastener.
