A method for handling product enclosures each containing a product and having a through opening. A five panel fiberboard folder is provided that includes first, second, third, fourth and fifth elongate panels each having opposite longitudinally extending sides, one longitudinally extending side of the fourth panel being joined to one longitudinally extending side of the third panel, and the longitudinally extending side of the fourth panel opposite the third panel being joined to one longitudinally extending side of the fifth panel. The fifth panel has a plurality of through cuts between its major surfaces each defining a hook portion of the fifth panel projecting toward a first end of the fifth panel, and the five panel folder has perforations affording separation of the fourth panel from between the third and fifth panels. The product enclosures containing the products are engaged with the hook portions of the fifth panel by inserting the hook portions through the openings in the product enclosures so that the product enclosures are supported along one major surface of the fifth panel. The folder is folded between the sides of the panels so that the first, second, third, and fourth elongate side panels form a longitudinally extending cavity having a rectangular cross section and the major surface of the fifth panel opposite the product enclosures is positioned along one major surface of the first panel within the cavity. The folded folder containing the product enclosures is moved to a different location. The fourth panel is separated from between the third and fifth panels, and the fifth panel and the product enclosures thereon are removed from within the cavity. The fifth panel can have a through aperture adjacent its first end from which it can be hung to display the products in the product enclosures.
摘要:
Two strip materials from which portions may be severed and used together as a releasably engageable fastener. Each strip material comprises a bonding layer in which are embedded a plurality of U-shaped monofilaments. Each U-shaped monofilament includes two headed stem portions adapted to engage the headed stem portions of the other strip material, and the monofilaments are rectangularly arrayed, and spaced to provide a number of headed stem portions per unit length that are different from and not a multiple of or evenly divisible by the number of headed stem portions per unit length on the other strip material in any direction so that upon engagement the rows of headed stem portions of one strip material cannot readily slip between the rows of headed stem portions on the other.
摘要:
A system is used for determining efficacy of a sterilization cycle. A biological sterility indicator exhibits fluorescence in response to biological activity which is indicative of bacterial growth in the biological sterility indicator. The biological sterility indicator is exposed to the sterilization cycle and is placed in a fluorescence reading apparatus. The fluorescence from the biological sterility indicator is read to obtain a first fluorescence reading. The fluorescence from the biological sterility indicator is re-read to obtain a second fluorescence reading. The efficacy of the sterilization cycle is determined based on the first and second fluorescence readings.
摘要:
A medical assembly, such as an artificial heart assembly, adapted to be implanted within a living subject is composed of an implantable data communications interface adapted to receive an encoded data signal from a data communications interface located outside the subject at a position remote from the medical assembly. The encoded data signal is transmitted in a plurality of periodic signal bursts, which are transmitted at a first frequency to represent a first data value and a second frequency to represent of second data value. Each of the bursts comprises a plurality of signal transitions having a third frequency greater than both the first and second frequencies.

A coated abrasive having a backing and an abrasive layer coated on the first major of the backing, wherein a cross-section of the abrasive layer normal to the thickness and at a center point of the thickness has a total cross-sectional area of abrasive agglomerates which is substantially the same as that at a point along the thickness which is 75% of a distance the same as that at a point and the contact side; a coated abrasive article having a bond system with a Knoop hardness number of at least 70; a coated abrasive article comprising abrasive agglomerates in the shape of a truncated four-sided pyramid; a method of making the coated abrasive article; and a method of abrading a hard workpiece using a coated abrasive article.
摘要:
A binding assembly including (1) a plurality of support strips; (2) layers of pressure sensitive adhesive (which could be repositionable, removable or permanent pressure sensitive adhesive) along front surfaces of the support strips; and (3) layers of release material on a rear surfaces of the support strips. The support strips are adhered together to form a support strip stack with inner edges of the support strips in alignment, with the layers of pressure sensitive adhesive on the support strips adhered to the layers of release material on adjacent support strips, and with the front surfaces of the support strips uppermost in the support strip stack. The binding assembly further includes binding means along the inner edges of the support strips that affords separation of the support strips and revolving of the support strips relative to each other around axes generally parallel to their inner edges. Only tension applied through a paper sheet adhered along the full length of the layer of pressure sensitive adhesive on the uppermost one of the support strips adhered in the support strip stack can be used to separate that one support strip from an adjacent support strip adhered to the layer of release material on the front surface of that one support strip and cause revolving of that one support strip away from the support strip from which that one support strip was separated.
摘要:
An electromagnetic device having a ferromagnetic core having first and second legs and a third leg wherein opposed pole faces define a gap. A source of latching flux retains an armature in contact with one of either of the pole faces. A primary coil and a secondary coil are coupled in tandem to the first leg of the ferromagnetic core. The second leg is saturable under the cumulative flux created in the first leg when the secondary coil allows only a unidirectional flux flow in the first leg. The saturation of the second leg transfers a portion of the operating flux from the second leg to the gap operably moving the armature mounted therein.
